<deasy> arokux2, it's from rhombus?
<deasy> so it's probably one
* deasy go in bed watch his movie and sleep
<deasy> good night people
<arokux2> night
<Turl> arokux2: according to hno, not yet
<arokux2> Turl, not yet? until release?
<Turl> arokux2: having a look at your patches, do you need style nitpicking or are you going to go through the details on a later date?
<Turl> arokux2: I dunno when, but it's not OSHW yet
<arokux2> Turl, not sure, I have no experience on what is better. comment on what is crucial to change in the first place maybe, then i'll do v2
<Turl> arokux2: I think your code editor has some weird notion of tab length
<arokux2> Turl, hm.. does it matter, tabs are not expanded
<arokux2> ?
<Turl> arokux2: well, it results on misindented code
<Turl> arokux2: 'git show' your first commit and you'll see it on the line wrapping of of_property_read_string_index and on the line wrapping on the dt clock names
<steev> mkdir -p lib/modules
<steev> rm -rf lib/modules/
<steev> wat?
<arokux2> steev, :)
<steev> i think that rm -rf is supposed to be cd
<steev> under setting up the rootfs
<arokux2> steev, fix our wiki :)
<arokux2> steev, yes, I'm aware of it
<steev> arokux2: i don't know what is being done there
<Turl> arokux2: + * FIXME: Should the credits be given to the original pile of code? <- yes, if you started from it
<arokux2> Turl, ah, there are extra spaces.. my bad.
<steev> yep, always
<Turl> arokux2: +/* FIXME: Remove this crap once everything works! */ <- needs fixing too
<Turl> arokux2: I think your editor is configured with tabs=4 spaces
<arokux2> Turl, maybe best you comment on ML?
<arokux2> Turl, no those spaces were added by hand or smth
<steev> more likely your editor expands tabs to spaces
<Turl> arokux2: I'm having a really quick look at it, I'll probably have a second look later and reply on ML
<arokux2> steev, no.
<steev> arokux2: there's a script to fix it either way
<Turl> steev: no, it's like it got a lot of extra tabs
<arokux2> Turl, "Remove this crap": will vanish once it passes all the reviews and gets testing..
<steev> oh
<Turl> arokux2: ok
<arokux2> Turl, ok, then feel free to drop you comments here
<arokux2> Turl, thanks a lot.
<steev> arokux2: the comment should be dropped if it's being worked on
<steev> cleanfile? i think is the script
<arokux2> Turl, does you mele run mainline?
<Turl> arokux2: dev_err(&pdev->dev, "failed to get I/O memory\n"); <- don't print needless messages, the kernel already does
<Turl> arokux2: no, it runs 3.4 as I need USB and a place to keep the rootfs
<steev> is this on the linux arm mailing list?
<Turl> steev: linux-sunxi on googlegroups
<steev> oh
FDCX_ has quit [Ping timeout: 256 seconds]
<arokux2> Turl, "don't print needless messages, the kernel already does": in this case it does not.
<Turl> arokux2: hm, well I take that back, it's not a kalloc :P
<Turl> yeah sorry
<Turl> noticed a bit too late
<arokux2> Turl, ok :)
<arokux2> Turl, no prob
Olaff has joined #linux-sunxi
<arokux2> Turl, so you'll have USB for Mele. where do you keep your rootfs?
<Turl> arokux2: mmc
<Turl> "fail1" could probably be just "fail" as there's just 1 of it
<Turl> +/* this is enabled by default, of not it should be
<Turl> + * enabled in U-Boot ---> hci_port_configure
<Turl> what is "this"? :)
<arokux2> Turl, hci_port_configure. yes this is weird comment. I wanted to change it actually but forgot :)
<Turl> arokux2: all those bits you use on sunxi_usb_passby could probably be #define's with proper names
Olaff has quit [Read error: Operation timed out]
<arokux2> Turl, ok
<arokux2> Turl, 8Gb USB Stick cost the same as 8Gb MMC, but we cannot boot from USB just now.
<Turl> yeah
<Turl> usb_phy_write is pretty unintelligible
Olaff has joined #linux-sunxi
<deasy> why these port are called mmc?
<deasy> yes yes i don't sleep :p
<Turl> deasy: multimediacard
<arokux2> Turl, do you mean readability? or why it is done the way it is done?
<deasy> there are little different with sd?
<deasy> difference*
<Turl> arokux2: I mean readability, yes; a lot of magic constants and stuff
<deasy> ow ow ow
<deasy> maybe it means mmc like compatible with several kind of memory card
<arokux2> Turl, I'm falling asleep, so leaving now. just send you comments here I'll see them tomorrow. thanks a lot.
<deasy> gn arokux2
<arokux2> deasy, gn
<Turl> night arokux2
<Turl> deasy: MMC and SD are two standards
<Turl> deasy: read the MultiMediaCard and Secure Digital wikipedia pages
<deasy> i know it
<deasy> i have in the past a nokia 6600 who use a mmc
<deasy> but how we can put sdcard on mmc on a10?
<deasy> i read it tomorow :)
<Turl> yes, you can use SD cards
<Turl> in fact most boards have microSD slots on them
<deasy> yes as my cubieboard

<TheViking> Would it be appropriate to add information about f2fs on the linux-sunxi wiki?
<oliv3r> TheViking: why?
<oliv3r> TheViking: you can put a link to wikipedia or or wherver the information lives, but having random info on random topics would just be duplication would it not?
<TheViking> oliv3r: The cubieboards (and others) use SD cards for storage. F2FS would ideally improve SD card life and performance. The linux-sunxi kernel is only 3.4 and the earliest version of the mainstream linux kernel with F2FS is 3.8...
<oliv3r> TheViking: that's what i'm saying you can put a little bit like what you said up there (which kinda is moot, since its not even in our kernel, and our mainline work doesn't have mmc driver yet) with a link to the f2fs sites
<oliv3r> but much more would be overdone
<TheViking> oliv3r: My keyboard is acting up. Hold on please...
n01 has quit [Quit: Lost terminal]
<oliv3r> TheViking: hehe, sure
n01 has joined #linux-sunxi
<TheViking> oliv3r: There is a f2fs backport project here:
hipboi has joined #linux-sunxi
<TheViking> oliv3r: As you can see, it is void of linux 3.4 patchsets...
<TheViking> oliv3r: According to this issue ticket: A user by the name 01micko found a solution to adding f2fs to 3.4 via the patches on the repo...
<TheViking> oliv3r: I have tested that on the current linux-sunxi 3.4 and currently have 3 days uptime. No visible issues so far. ( I use it as my rootfs on an sd card )
<oliv3r> hehe, well if you port the patch back and make it work in our 3.4; good!
<oliv3r> until then i'd keep the noise on the wiki to a minimum
<oliv3r> but hey, it's an open wiki, you can write whatever you want :)
<oliv3r> i just shared my opinion as you asked for it :)
mcbrick has quit [Remote host closed the connection]
<TheViking> oliv3r: If you are suggesting I try and port f2fs for linux-sunxi's repo, I have never done anything significant with git or anything developer related for that matter.

<TheViking> Like I need another account online :-P (GitHub)
<diego71> TheViking: But you don't really need a github account. You can clone on your pc, and make patch from there
<TheViking> How would I submit it to be merged into the linux-sunxi kernel?
<diego71> You can send your patch on the mailing list
<oliv3r> TheViking: git send-email
<oliv3r> or git format-patch
<oliv3r> ideally you'd metnion the commit hash(es) that needed to be cherry picked from upstream; and then a (small) patch to make it all work

<rellla> no window manager here, i have to start everything from console. how do i tell mplayer to use X? mplayer is telling me, that file is played but i don't see anything. too far away i used X the last time ...
<mnemoc> wingrime: please paste me the subjects in /q so I can take a look and merge after leaving work
<rellla> wingrime: no cubie here atm, but sth. like "-vo output missing" is popping up
<mnemoc> rellla: export DISPLAY=:0.0 should do the trick
<oliv3r> rellla: export DISPLAY
<oliv3r> crap
<oliv3r> i'm to slow
<wingrime> mnemoc: first time V4 in linux sunxi?
<wingrime> rellla: they right
<mnemoc> wingrime: the cedarx unification was also v4 iirc
<steev> how to get rid of the stupid android loglevel garbage when running linux? it makes it extremely hard to read boot up
<mnemoc> build a not-android kernel...
<steev> i removed all of android from the config
<rellla> mnemoc: uahh. i'll try that, since everything with libvdpau-sunxi and xf86-video-sunxifb seemed to be right. mali test prog also don't show up ;) do i need ssvb's module for doing the mplayer test?
<steev> i also removed the "loglevel=${logleve}" from the setargs command, and loglevel isn't set in my boot.scr
<steev> loglevel*
<wingrime> mnemoc: with cedar I still have no clear decide
<rellla> oliv3r: de->de is way too fast :p

<mnemoc> ok
<oliv3r> rellla: hmm?

<mnemoc> but maybe adding an option to disable it might be a good idea
<oliv3r> mnemoc: link
<mnemoc> youtube -> charbax
<mnemoc> Tsvetan forwarded it on G+ too
<steev> cnxsoft ?
<steev> easier to find his videos
<mnemoc> charbax = armdevices

<mnemoc> got confused
<wingrime> mnemoc: me too
<wingrime> mnemoc: facepalm
<wingrime> mnemoc: ok, then wait ssvb for decision
<oliv3r> charbax is sometimes a bit of a douche
<oliv3r> lol
<oliv3r> but i do enjoy watching the vids
<oliv3r> sorta
<mnemoc> charbax interviews are better than no interviews :p
<ssvb> wingrime: what decision? (I don't follow your chat)
<Tsvetan> oliv3r at least he present news :)
<oliv3r> Tsvetan: exactly, I did say I enjoyed watching :)
<wingrime> ssvb: leave cache w/o in a20 kerenl
<oliv3r> as he brings cool stuff
<oliv3r> badly reported news is still news :)
<Tsvetan> when I saw this video I asked Allwinner for A23 datasheet and they said we do not have yet :))) but Eva says the chips will be in production in October
<ssvb> wingrime: with cedar it would be nice for someone to 1) actually provide some benchmarks showing how slower it gets without cache 2) try writecombine mapping
<zumbi> Tsvetan: what's A23?
<Tsvetan> kinda reminds me Olimex we released imx233-NANO and next day people start asking where is the user manual which we didnt start :)))
<zumbi> Tsvetan: is A23 using SGX?
<Tsvetan> A23 is A20 but in TQFP package as A13
<Tsvetan> lower cost A20
<zumbi> nicee
<wingrime> Tsvetan: as expected
<zumbi> Tsvetan: btw, do you know if rockchip chips are available too?
<buZz> Tsvetan: A23 probably lacks sata?
<Tsvetan> zumbi - sure they are, Rk3188 is all around in TV boxes etc
<wingrime> mnemoc: so, than cedarx merge patch should stay for a while
<Tsvetan> buZz probably same as A13 - LCD and USB hosts

<oliv3r> Tsvetan: yeah they make chips and drivers without user manuals
<arokux> hi guys
<ykchavan> buZz, I am curious to know why you mentioned ' keep in mind berryboot is not a recommended boot image for A10 devices' in wiki.
<buZz> because its made for raspberry pi
<ykchavan> I see
<arokux> steev, still fighting with log messages? I know the cure.
<steev> arokux: i'm all ears
<steev> i figured it is because of LOGLEVEL=7 in the kernel
<rm> ykchavan, because it uses some sort of its own weird system for loading the kernel
<rm> and people fail to update their kernel following the usual sunxi howtos, then waste everyone's time trying to get help why
<steev> still waiting on the compile, since we like to enable everything and the kitchen sink
<rm> only a long time later it turns out they used berryboot
<rm> nuke that crap from orbit
<oliv3r> a23 is dualcore A13, probably sun8i
* mnemoc hopes for another sun7i
<mnemoc> they are running out of numbers
<oliv3r> how so?
<ykchavan> thanks for information rm.
<oliv3r> numbers kinda go into invinity
<wens> mnemoc: they can always go for 2 digits
<oliv3r> sun10i
<oliv3r> sun9i probably will be a31 followup
<oliv3r> so sun10i shoudl be sun47i brother
<arokux> steev, in kenel hacking turn of low level debugging
<oliv3r> what's the a23 allwinner video's title?
<oliv3r> as user/Charbax has many videos
<oliv3r> ohhh found it
<oliv3r> duh
<steev> arokux: er, interesting
<oliv3r> 2 days ago
<steev> arokux: are there a bunch of printk's hidden behind DEBUG_LL or something? you shouldn't have to turn off DEBUG_LL to get rid of duplicate messages
<arokux> steev, patches are welcome. I said I know the cure.. :)
<steev> arokux: i am talking the messages like <6> blah
<steev> not ALL the messages
<arokux> steev, those will be not all messages. the problem is when DEBUG_LL is on the messages get duplicated
<arokux> steev, to avoid duplication you need to disable "Kernel low-level debugging functions (read help!)"
<steev> arokux: yeah that's DEBUG_LL
<steev> i'll see if i can find some time for it on friday
<steev> later today i have to do amd64 stuff, and then tomorrow i promised someone i'd look into an issue with Kali on the ODROID-XU
<arokux> thanks steev no worries.

<shineworld> Ok, for actual AllWinner 4.2.2 android partitions I watch either original nand boot and what in xxxx.rc and all other android files which have some relation with /dev/...
<shineworld> the partitions table is changed than 4.0.4 and what declared in linux-sunxi wiki pages
<shineworld> a new env/databk are entered
<shineworld> I guess my new table is right, at least comparing any thing with xxx.rc files

notmart has joined #linux-sunxi
<shineworld> I need a CB2 working Android on SD fastly ...
<shineworld> the 11 partiotions question is because the /dev/sdc4 is an extended partion (id=5) You know primary are only 4 so first 3 are real, 4 is extended which implement the rest
<shineworld> this is the right way to have required 10 real partitions on SD
<shineworld> 3 real, 1 extended which inlcude remaining 7
<shineworld> About private: private compare in boot list but NEVER in android files ... so I've removed it
<JohnDoe_71Rus> shineworld: but at the boot, they 11 real with private
_enrico_ has joined #linux-sunxi
<shineworld> have you tried to add that ? and boot ?
<JohnDoe_71Rus> yes. my logs in mail with 12 partitions
<shineworld> try a "grep -lir "private" . in android root files to see if someone use it
<shineworld> I can be wrong in my analysis :)

<arokux> soldoKyn, sorry ssvb and libv are the people working on this.
<arokux> soldoKyn, I can only point you to:
<TheViking> Shineworld: "...MM memory managemnt (kernel panic) throw by some zygote internal operation..." I built an android 4.2 image for a no-name rockchip tablet a while back and had something very similar like this. Compiling with thumbcode disabled seemed to fix/get around the problem (--disable-thumb2 flag IIRC)
<shineworld> TheViking, how to change this setting ?
<oliv3r> arokux: i'm not sure if mainline folk will be happy to take a patch without a real name
<arokux> oliv3r, wingrime read a P.S. please :p
<soldoKyn> arokux: ok, thank you!
<TheViking> Shineworld: My build environment was on a VM to keep things tidy, but I no longer have that VM. I don't remember, I'm sorry.
<shineworld> I'm using a VM too (my host is a MAC)
<soldoKyn> ssvb: libv: can I turn the question to you?
tzafrir_laptop has joined #linux-sunxi
<shineworld> ... download of sdk require 23H... so slow server
<TheViking> Shineworld: Maybe adding "-disable-thumb2" to the CFlags?
<shineworld> I will tray this evening at home ... thank you for precious suggestion
<TheViking> shineworld: Thumb2 is a pretty useful optimization for android's JVM. I couldn't figure out why it broke stuff.
<arokux> is Charbax a noob or he's just playing one
<shineworld> some weeks ago someone suggested me a maillist with a patch but was too complicate for me to act it
<TheViking> act it?
<shineworld> do apply correctly
<shineworld> *to

<oliv3r> i'm just curious at this point
<oliv3r> i compiled a new 3.11 kernel for my server the other day, and idsabled pci-platform for usb
<oliv3r> and all of a sudden, my USB 1.1 devices stopt working
<oliv3r> only USB 2.0 devices worked
<oliv3r> due to the missing usb 1.1 controller
<oliv3r> so you say you tested keyboards, mouse and stick; which means usb 1.1 and 2.0 devicese (unless the usb stick is 1.1 too :p)
<oliv3r> well it IS backwards compatible
<arokux> oliv3r, yes, the mouse and the keyboard I have worked :)
<oliv3r> in other words, on a PC, you need USB 1.1 (ohci) drivers for 1.1 devicse, EHCI driver ONLY does 2.0
<oliv3r> so your patch makes it _sound_ that it's *only* EHCI
<arokux> oliv3r, usb stick is 2.0 i think..
<oliv3r> but i don't know how it works with this aw device of course
<arokux> oliv3r, yes, commit messages say explicitly *only* EHCI support.
<arokux> oliv3r, you are welcome to test it, just say what your device is i'll add dt bindings and you can easily test.
<oliv3r> cb2 and olimexino :)
<arokux> oliv3r, olimexino - which one?
<oliv3r> so (i'll ready your patch in a mminute) do both drivers? or does the hardware do both simultaniously?
<oliv3r> a20
<oliv3r> cb1 i have too :)
<oliv3r> but don't worry
<oliv3r> i'll add the devicetree nodes :)
<arokux> oliv3r, that would be cool, but can take some time, however mele dt is a good basis.
<arokux> oliv3r, "so (i'll ready your patch in a mminute) do both drivers? or does the hardware do both simultaniously?" I do not get the question.
<arokux> oliv3r, so you have? A20-OLinuXino-MICRO
<soldoKyn> ssvb: libv: for completeness: that's my Xorg.log and I'm using a Debian (from olimex) with a kernel compiled from sunxi 3.4 branch and with graphics driver compiled from (libdri2 compiled from git repo listed there and mesa-egl dir moved like listed in "common pitfalls") thanks!
<shineworld> TheViking, what I get is "kernel BUG at include/linux/mm.h:791" during zygote execution
shineworld has quit [Quit: Sto andando via]
<oliv3r> arokux: from what I understand, and my experience on x86; if you want USB support you need OHCI and EHCI drivers
<oliv3r> I know usb 2.0 is backwards compatible with 1.1 devices
<oliv3r> but you still need an OCHI driver to have this backwards compatibility
<oliv3r> if you compile ECHI without OCHI, you only have 2.0 devices working (storage etc)
<arokux> oliv3r, I see. maybe it is needed for ARM SoCs too. but having EHCI only works so I thought I'm fine
<oliv3r> but you can't use a mouse, as it requires 1.1
<oliv3r> now you say you used a keyboard + mouse; which worked, so thats strange
<oliv3r> what does lsusb say? USB 2.0 hub and USB 1.1 hub is what you need to see
<oliv3r> if you only see USB 2.0 hub; you don't have USB 1.1 support afaik
<arokux> oliv3r, hm.. well cat /dev/input mouse has output some noise, I've considered it working :)
<arokux> oliv3r, so I will do more thorough testing
<oliv3r> lol
<oliv3r> yeah lsusb should give you a lot interesting information as well, also /sys/*/usb/* something gives info

<oliv3r> arokux: basically, I don't know how OCHI and EHCI work together on arm, or how it works with the AW code
<arokux> oliv3r, have I done smth wrong?
<oliv3r> btw, i only see your 0/4 mail, where's 1/4 - 4/4?
<oliv3r> arokux: i'm just reading alexey's review, where he says 'FET gate to usb'
<arokux> oliv3r, yes. Turl have seen them
<oliv3r> maybe it's ower on the list :)
<arokux> oliv3r, I haven't understood the FET bit, have no idea what it is, will look into it.
<libv> soldoKyn: what application are you running?
<arokux> oliv3r, then click on subject
<arokux> oliv3r, wrong link
<soldoKyn> libv: the test from sunxi-mali git...
<libv> soldoKyn: did you run gdb on it
<soldoKyn> libv: I'm doing it right now...
ykchavan has quit [Quit: Leaving]
<ssvb> soldoKyn: do you have the right permissions for /dev/mali and /dev/ump (correct ownership, and you user in the 'video' group)?
<libv> would that really cause a segfault?
<ssvb> don't know, but the first line of the log implies that there is something wrong with DRI2
rz2k has joined #linux-sunxi
<ssvb> also he got EGL Vendor: "Mesa Project", that's not the mali binary driver
atiti has joined #linux-sunxi
<libv> ah, right, explains the dri stuff, seems that binary drivers wasn't followed
<ssvb> soldoKyn: you can try to run ldd for and to see what is really used in your system
<libv> this is probably still there: /usr/lib/arm-linux-gnueabihf/mesa-egl
<oliv3r> arokux: the FET bit is basically 1 gpio to enable/disable power; e.g. a regulator, if you look at the ahci patch (or the hackberry emac) both use a 'fet switch' to enable power too
<arokux> oliv3r, have you seen my code? I use regulator_enable stuff
gnufan has quit [Ping timeout: 245 seconds]
<soldoKyn> ssvb: libv: uhm...I think I've broken something trying to build glmark for a performance test (I had to install some packages with apt and maybe some of them were just from mesa). I tried ldd command with this result:
<ssvb> soldoKyn: do you also have /usr/lib/ ?
<libv> a20?
<libv> so you're running r3p2-01-rel2
<ssvb> soldoKyn: it is possible that your version of debian has reshuffled the shared libraries placement and the "common pitfalls" section needs to address this
<ssvb> libv: not yet, sunxi-3.4 kernel is still using r3p0 mali module
<libv> ah, ok
<soldoKyn> ssvb: yes, I've got that "chain": ->, ->, ->
<ssvb> soldoKyn: looks right, now you need to move mesa out of the way
<ssvb> soldoKyn: ldd for your gles application can reveal which libraries are going to be used
<wingrime> arokux: about FET
<soldoKyn> libv: excuse me is -> (not GL!!!)
<arokux> wingrime, it would be best if you show me some example
<wingrime> arokux: some vendors use FET transistor like key that enable or disable usb
<libv> soldoKyn: ok then :)
<wingrime> arokux: port
<wingrime> arokux: you have trun some gpios to 1 for enable usb host
<arokux> wingrime, ok, so how that applies for sunxi? I need to put a GPIO to out and let it output "1" so that the VBUS is powered. it is not for enabling of the usb host.
<arokux> hipboi, you have even more spam on
<wingrime> arokux: check some board schenematics
<wingrime> arokux: mars bord have this keys as I remeber
<arokux> wingrime, I do not understand what are you trying to tell me. USB EHCI works as is.

<arokux> wingrime, ah, ok. well, I do not have the hardware :p so patches are welcome. tonight I'll add bindings for the cb2 and olinuxino a20 so ppl can test.
rz2k has joined #linux-sunxi
<oliv3r> arokux: no i haven't, i only see 0/4 (the cover letter)
<arokux> oliv3r, so wingrime is talking about something else as you see.
<oliv3r> i should see it :)
<oliv3r> but i haen't found it yet
<oliv3r> still need to read some mails
<ssvb> soldoKyn: btw, after you get mali binary drivers working, the performance is not going to be great in your setup, but it can be improved significantly with some tweaks
<arokux> oliv3r, I've given a link to gmane... please give further comments after actually looking at the code :p
<oliv3r> arokux: lol yeah if i have some more time
<arokux> oliv3r, no worries. just comment on the code :)
<soldoKyn> ssvb: libv: I confirm that was mesa the problem. removing some mesa packages used for building glmark leads to a working mali binary driver! thank you so much!!
<soldoKyn> ssvb: where I can get these tweaks?
<oliv3r> wingrime: while still backreading, the regulator framework should take care of the FET
<panda84kde> soldoKyn: ssvb: are you referring to line 284 of Xorg.0.log or even something else?

<oliv3r> that's a big fat nono
<oliv3r> your list of includes looks awefully shor
<arokux> oliv3r, this is how it should be done, however.
<oliv3r> including a C file?
<arokux> oliv3r, yes.
<oliv3r> O.o
<arokux> oliv3r, check out ehci-hcd.c
<oliv3r> i am :)
<arokux> oliv3r, "your list of includes looks awefully shor" mm.. could be, forgot to clean it
<wingrime> arokux: sort includes list in alphabet order
<arokux> wingrime, is there a requirement like this??
<oliv3r> but as far as I know, you should never, ever include a C file :)
<libv> oliv3r: depends
<libv> oliv3r: i sometimes do that for big tables
<arokux> oliv3r, from every rule there is an exception...
<oliv3r> libv: exceptions prove the rule :)
<oliv3r> arokux: I see, oh that's fugly :(
<wingrime> libv: if you have time you can review my new patches, still no comments
<oliv3r> wingrime: which ones?
<wingrime> oliv3r: for disp
<arokux> oliv3r, patches against mainline usb subsystem are welcome, I think :p
<wingrime> oliv3r: delay replace patches, cos/sin table divide . tvenc regs
<oliv3r> wingrime: ah ok i replied to some of those; and libv did reply to some of them too?
<oliv3r> wingrime: the cos/sin table devision sounds sensible i suppose
<oliv3r> tvenc regs you never replied wether we really need _REG suffic
<oliv3r> suffix*
<oliv3r> arokux: yeah I guess it would require some cleanup; cause right now it's very ugly :)
<wingrime> oliv3r: _REG suff for somethins make it mainline
<oliv3r> arokux: i think OHCI did get cleaned up recently
<oliv3r> wingrime: mainline suggest adding _REG to register defines?
<oliv3r> lemme se some of maxime's patches
<wingrime> oliv3r: no, but I think SUNXI_TVENC_ names space may include not only regs
<oliv3r> he actaully renamed _REG registers and dropped it i think
<oliv3r> wingrime: personally, I think the rename is good; but _REG is a little too much

<wingrime> oliv3r: than send ACK, I will contine tvenc hacking
<arokux> oliv3r, have you read the comment to that function?
<oliv3r> arokux: i'd rename all USB to USB0 and USB1, as that's logical; I know the datasheet uses USB1 and USB2 for host, as it names USB0 for gadget, but in the host driver itself, it should be just what it is imo, USB0 and USB1
<arokux> oliv3r, mainline ohci uses the same "include C file" scheme.
<oliv3r> arokux: yeah that's why i said 'omg that's fugly' :)
<arokux> oliv3r, but then you said: <oliv3r> arokux: i think OHCI did get cleaned up recently
<oliv3r> arokux: and your comment wasn't very clear on what the crap was :)
<oliv3r> arokux: well i saw the seperation between platform and PCI seperation for OCHI, so SOMETHING was done ther e;)
<arokux> oliv3r, I would like you to post your comments in e-mail reply to my patches, this is much more effective. and we can keep track of the issues.
<oliv3r> arokux: make sure you tripple check that writeb actually works as expected. I know for sid, the registers are read-aligned on 32 bit boundries so you _have_ read 32 bits at a time
<oliv3r> arokux: i don't have them (yet?)
<arokux> oliv3r, re: writeb: ok.
<Amnience> what's the speed of the USB0 port when using it as a host?
<arokux> oliv3r, ok, I think you'll get them.. or use gmane to reply. irc isn't appropriate place for comments like this.
<Amnience> I'm getting 24MB/s download and only 12MB/s upload
<oliv3r> arokux: ew magic values! :p 'magnitute' :p
<oliv3r> Amnience: USB ethernet?
<Amnience> no, removable storage device
<arokux> Amnience, tell me how to measure it and I will
<Amnience> i.e. USB HDD
<oliv3r> Amnience: that doesn't sound too bad
<oliv3r> Amnience: did you try the regular host port?
<arokux> Amnience, your USB HDD can be a bottleneck too...
<Amnience> erm dd if=/dev/zero of=/mnt/disk/test.img bs=16k count=8192
<Amnience> regular host ports work fine
<Amnience> 24/24 both ways with dd
<oliv3r> Amnience: it's quite possible that the OTG port is slower, are you using 3.4 kernel?
<Amnience> I was copying a 100MB file ftom tmpfs to disk and back
<Amnience> 3.4.61
<oliv3r> Amnience: did you flush your cashes inbetween?
<oliv3r> Amnience: well the mUSB is probably better; but that's only in mainline
<Amnience> I copied a different file
<Amnience> bottom line is this USB0 only uploads 12MB/s from device to HDD.

atiti has quit [Remote host closed the connection]
<Amnience> Question. Could it be the USB cable?
atiti has joined #linux-sunxi
<Amnience> I got this USB mini B to host A from ebay
<Amnience> I use it to interface with a sata HDD dock via another USB A to B cable
<Amnience> When I plug in the cable from ebay into cubieboard
<Amnience> I notice some dmesg output
<Amnience> like a host driver being loaded or something along those lines
<Amnience> doesn't happen when I plug a normal USB A to mini-B cable
<oliv3r> could be a ton of things, but I would personally be not supprised at all, if OTG is slower
<ssvb> panda84kde: yes line 284 of Xorg.0.log at is definitely a performance problem
<ssvb> soldoKyn: setting fb0_framebuffer_num >= 3 in the fex file is one tweak
<Amnience> I'm going to try to rule out the cable by making my own cable with no hidden circuitry
<Amnience> then again I was wondering... I saw there are some options for OTG support in the kernel config
<ssvb> soldoKyn: but also the r3p0 mali drivers can use only one PP core instead of two in Mali400 MP2, and the mali clock frequency is set a bit too low right now
<Amnience> and I saw some options to configure USB0 in the FEX file
<Amnience> do you think changing the fex options to host only along with the kernel will help?
<oliv3r> Amnience: i don't think we use the musb driver in 3.4 yet; so that driver is qualitivly poor to begin with; i wouldn't invest too much time there
<oliv3r> Amnience: fex options probably only influence poweron GPIO etc
<rm> <Amnience> bottom line is this USB0 only uploads 12MB/s from device to HDD.
<rm> that's correct
<rm> cable is unrelated
<rm> the OTG port is speed-limited and some devices (like webcams) may not work in it at all
<Amnience> is there a way to use it host-only without the limits?
<Amnience> yeah, couldn't get an external usb sound card to work on it.
<rm> says: "This is a hardware limitation which we
<rm> will likely not be able to work around."
<rm> so maybe we can't
<Amnience> hmm, well that's good to know so that I won't waste time on pointless things
<arokux> rm, is this hardware limitation?
<rm> hansg say so
<Amnience> though why is the speed limited only in one direction?
<oliv3r> hardware error
<oliv3r> :p
<oliv3r> design mistake :)
<Amnience> :-/
<tgaz> is there a list of known issues with usb0 somewhere?
<Turl> maybe it has no DMA implemented
<Turl> the driver is pretty crappy after all
<oliv3r> with the mbus driver, it might be worth investigating
<Turl> oliv3r: does your ahci driver work btw? :p
<oliv3r> Turl: well i still need to add the dt
<oliv3r> need your clocks
<oliv3r> and lots of time to actually test it

<oliv3r> what i'm curious about, some drivers have been allwinnerified (fex)
<oliv3r> but what if I don' thave the onboard version, but an external USB stick :)
<atsampson> if you have an offboard rtl8192, then you plug it in, udev loads the module and it powers up the internal one too ;)
<ssvb> merbanan: as a matter of fact, not all the neon code in FFmpeg is perfect
<oliv3r> atsampson: doesn't the fex check for usb_para or some shit?
<merbanan> Lengths supported by the transform: Internally, the functions utilize a radix-4 decimation in frequency(DIF) algorithm and the size of the FFT supported are of the lengths [16, 64, 256, 1024].
<merbanan> not impressed
<arokux> oliv3r, the people including me tend to agree that the _defconfigs should be for all: tablets and boards. also it should include modules for the hardware that is supplied by EOMs - wifi modules etc.
<oliv3r> if I hack on it, and i build my own kernel; I know how to do make menuconfig and idsable what i don't want
<oliv3r> joe user, who just wants to compile his kernel because its cool; wants a working _defconfig
<oliv3r> distro builder, could run a custom kernel config, but most of the time would rely on the joe user config anyway
<arokux> oliv3r, sunxi_defconfig should not include support for all sound cards out there, do you agree?

<popolon> at least for efficient math function, between auto-vectorization and perhaps more optimized one ???
<ssvb> well, another similar library (liboil) did not seem to have much real success
<atsampson> if you look at what hansg's done for the fedora kernel, he's split the config up into multiple chunks...
<atsampson> you could have a "sun4i generic" config chunk and an "all USB devices" separate one?
<arokux> sun4i generic - is what we want to have in sun4i_defconfig
<arokux> at least me, hno wingrime and steev :)
<oliv3r> arokux: of course; my A10 device doesn't have a 3'5mm jack, so i can't connect it to my stereo, but I do have an USB sound card
<oliv3r> arokux: just some random use case
<oliv3r> arokux: but i can give you a few more :)
<oliv3r> there's no reason to limit the amount of modules users have available
<arokux> oliv3r, well for me that is not a problem as modules won't blow up the kernel image. however me and I think most ppl here have no idea what USB sound cards should modules be built for. some of them are not used anymore. also, you cannot see *all* the use cases ppl will have. the other way i.e. including the most probable hardware support seems to be more reasonable. it is not a distro config after all.
ganbold_ has joined #linux-sunxi
<oliv3r> exactly, you don't know what users will want or need
<arokux> oliv3r, so? should we build a distro-like config?
<arokux> how come EOMA68-A20 isn't open source hardware???
<buZz> why should it be?
Mithrian has joined #linux-sunxi
<arokux> buZz, mm.. it should't I just thought it is, because the community is backing it so much
<buZz> the community is backing using proper power supplies, still, not many power supplies are open source hardware ;)
<arokux> buZz, I meant irc, mailing lists and stuff
<buZz> yes
<buZz> i know what community means
<popolon> didn't know liboil, that's used by MLT
<popolon> and so gstreamer
<arokux> oliv3r, it will then be called "distro-config", we however want to come up with sunXi_defconfig
<oliv3r> arokux: yes, but USB opens a load of options for drivers
<oliv3r> since every user can pickup any USB device and just plug it in
<oliv3r> why would you NOT wanna put it in? you even said so yourself, it only takes some extra initial compile time, and it's only a little bit of filesystem space for the modules
<oliv3r> it doesn't really get in the way
<arokux> oliv3r, you are 100% right and I agree.
<arokux> oliv3r, so maybe we just build everything that depends on USB? or how should we proceed?
<oliv3r> yeah i'd think so, any usb driver should be M
<oliv3r> for the rest, there aren't as high as a requirement
<arokux> oliv3r, following your logic we should build support for all major filesystems too.
<oliv3r> i suppose so yes :)
<oliv3r> but only ext4 as Y for now
<arokux> oliv3r, why should be any fs be built as Y?
<oliv3r> arokux: so you can boot your kernel?
<tgaz> with ramdisk, that isn't really needed, right?
<arokux> oliv3r, why not as module in initramfs?
<oliv3r> but i don't want an initramfs! :p
<oliv3r> but FS is probably a lesser issue
<oliv3r> most users don't randomly plug in a special fs
<oliv3r> it'll be either fat, or ext most of the time, if not nearly always
<oliv3r> but yeah, in theory, all modules
<oliv3r> but then the debate goes hardware vs other features, a fs isn't a hardware driver I guess :)
<oliv3r> but athat's up for debate yeah
<oliv3r> arokux: but yeah there is a line that needs to be drawn somewhere of course
<arokux> oliv3r, well either it is a distro-like config or a more minimal config.. :) you want it to be distro like. it is ok for me.the only problem I see is to predict what devices will be connected to the boards.
<oliv3r> well we can't include every possible driver, tehre's GPIO drivers that we can't anticipate, but USB, we can anticipate that anything is game, since it's just plug and play
<oliv3r> also, GPIO drivers are board specific really, you don't really plug that normally into a STB or tablet

<ZetaNeta> afaik A13 is pincomaptible with A10?
<oliv3r> ZetaNeta: no
<oliv3r> A13 -> A23; A10 - > A20
<ZetaNeta> Well, i remember there were 2 allwinners which are
<ZetaNeta> oh.....
<ZetaNeta> 4 allwinners :D
<libv> 5 actually, but the 5th is the uncle we do not like to talk about :p
<ZetaNeta> Can you atleast call the name?
<oliv3r> A31 and A31s
<libv> well, due to lifestyle choices, that uncle contracted a rather nasty disease
<oliv3r> the uncles retarded problem
<specing> PowerVR?
<oliv3r> brother!
<libv> specing: sssh!
<ZetaNeta> I am doing a list of "unique retarded features" i am going to implement in my ARM book
<arokux> does this PowerVR have at least good performance?
<libv> arokux: perhaps, but as with things powervr, it might be even harder to get at
<libv> this performance
<oliv3r> arokux: who cares :)
<oliv3r> don't count on linux binaries; android only if your really lucky
<arokux> oliv3r, you seem to be very biased. users who buy tablets care.
<oliv3r> ZetaNeta: EOMA68-A20 netbook :)
<Montjoie> Does someone have a working .config for linux-sunxi kernel sources for Cubieboard2 (A20)
<oliv3r> arokux: PowerVR is closed source propriatary crap
<specing> arokux: doubt it
<oliv3r> arokux: if you are 'okay' with that, then your choices are weird :)
<specing> arokux: if they did, they would buy Intel tablts
<oliv3r> specing: or samsung tablets :p
<ZetaNeta> oliv3r, EOMA68 is the one of the greatest inventions ever
<ZetaNeta> in arm industry
<specing> oliv3r: samsung has good chips underneath?
<oliv3r> specing: if your lucky and get an exynos
<specing> My friend is always bitching about the thing being a clusterfuck
<oliv3r> exynos isn't really bad is it?
<specing> its still ARM
<oliv3r> specing: hehe, yeah i know team-hacksung and replicant aren't tooo happy with samsung/exynos
<ZetaNeta> oliv3r, Is allwinner any open? Can i write that it is, or not for the glory of satan (strikethrough) for marketing purposes?
<arokux> specing, well price vs perf
<oliv3r> ZetaNeta: a10, A13, a20 and a23 could be considerd 100% open
<oliv3r> ZetaNeta: after we're done RE-ing stuff :p
<specing> oliv3r: lmao @team-hacksung
<ZetaNeta> :DDDDD
<oliv3r> ZetaNeta: like lima and cedarX
<specing> arokux: think about all the time you waste hacking on ARMs
<oliv3r> a31 has powerVR, which is a huge problem :)
<oliv3r> also, always remember, libv said, powerVR is the biggest utter crap of GPU's :)
<specing> arokux: if I looked at the difference between an ARM tablet that I bought and an Intel one, its only 200$, and if I look at how much my time is worth hacking those (and I still haven't made them work), it would be 0.1$ / hour at best
<arokux> specing, and? i'm not a "tablet user" I love to hack. but i'm not biased. for hacking I'd pick Mali, for my brother that plays 3D game i'd buy PowerVR
<libv> and, like robclark, libv is still in therapy for having been exposed to pvr
<oliv3r> libv: lol
<specing> hhahaha
<oliv3r> arokux: some people actually do care about open source and it being out in the world
<oliv3r> arokux: and powervr is probably the worst choice in that regard
<arokux> oliv3r, well you must know I do, but there are lines that should be drawn.
<oliv3r> arokux: so hell yeah i'm biased, as I care about OSS, from that warm and fuzzy inside place
<oliv3r> arokux: annhilate all propriatery users? :D
<deasy> i confirm than powervr is crap
<deasy> even their proprietary driver is a crap
<deasy> they are even not able to do performance in 2d
<deasy> (in my experience)
<arokux> oliv3r, i'm sacrificing a lot, but you sacrifice everything..
<mripard> arokux: where did you send it to?
<Turl> mripard: linux-sunxi
<oliv3r> arokux: if I have to; yeah
<merbanan> libv: is the actual hardware crap also, or only their software ?
<oliv3r> merbanan: libv worked on the actual drivers while working for ... I forgot, i think nokia
<deasy> merbanan, i think than both is crap
<deasy> as they are even themself not able to do a good driver for their hard
<deasy> (by good driver i mean decent performance at least in 2d)
<deasy> are*
<deasy> but if people want to reverse powervr , do it
<deasy> all thing reversed and open are good
gnufan has quit [Ping timeout: 264 seconds]
<deasy> and maybe someone in this world is able at least to do better 2d perf than the owner himself...
<oliv3r> Turl: where are the ahb_gates numbers defined?
<oliv3r> Turl: i bet it's not related to bit numbers :)
<arokux> deasy, why do you think powervr is bad?
<deasy> arokux, because i have get one in the past...
<Turl> oliv3r: they are, read the fine binding documents :)
<deasy> and even old igp intel as 915(or something like it) are better in 2d
<oliv3r> Turl: i was looking at the wrong kernel dir so couldn't find them :p
<deasy> (far better)
<oliv3r> Turl: hmm, do we even know ahci muxes? is it even mux or something that's just always tehre'
<deasy> their driver give the sensation to be slower than vesa rendering...
<oliv3r> Turl: looks like they are dedicated pins!
<deasy> <=== poulsbo user
<deasy> all poulsbo user can say than powervr is crap
<arokux> deasy, and now you nave a Mali thingy and see it is better?
<deasy> i have not hdmi screen :)
<arokux> mripard, ?
<deasy> when i get one i can say you it
<Turl> oliv3r: let me check the wiki :p
<deasy> but the fact than powervr is against open driver as nvidia is not encouraging for buy their crap
<arokux> oliv3r, I just try to be more pragmatic you know. that is all. i see it the same way Torlvalds saw it while using BitKeeper
<oliv3r> yeah T20, T21, U20 and U21 aren't defined on the wiki; i checked he olimexino schematic for those
<oliv3r> arokux: yeah and torvalds got flamed for that plenty :) and he corrected his ways :)
<oliv3r> and its no secret that torvalds isn't really a HUGE oss enthousiast :)
<arokux> oliv3r, not because of flames ;)
<oliv3r> arokux: think more like RMS
<deasy> oliv3r, links! or it not happens
<arokux> oliv3r, how do you think programmers will earn there livings by doing everything open source?!
<deasy> oh no sorry
<deasy> misunderstand
<oliv3r> arokux: i'm sure all these kernel devs must be dirt poor by now
<deasy> it's ok
<Turl> oliv3r: maybe mripard recalls, he wrote all of pinctrl :)
<oliv3r> Turl: i think it's fixed pins
<oliv3r> Turl: like usb etc
<Turl> oliv3r: yeah, poor people with chromebook pixels :)
<oliv3r> arokux: you CAN make money using OSS; personally I think oss is the only proper future :)
<oliv3r> but i also think knowldge should be available to anyone willing to learn
<arokux> oliv3r, why you do not do it then? :p
<oliv3r> an education should not be something only the rich can afford
<oliv3r> arokux: look at mripard ; how do you think he earns his living?
<oliv3r> arokux: because i'm still a student :)
<arokux> oliv3r, not everything can be open source -- this is my point.
<oliv3r> arokux: yes it can :)
<deasy> of course it can
<arokux> oliv3r, how can something exactly like Photoshop, AutoCAD etc. be open source?
<deasy> and for an hacker...everything MUST be open...
<oliv3r> arokux: ask the gimp developers
<deasy> except if he like challenge :D
<oliv3r> deasy: also when you want security, it has to be
<arokux> oliv3r, gimp != photoshop
<oliv3r> propriatery software is by default insecure
<deasy> i know oliv3r
<oliv3r> arokux: that's all momentum
<oliv3r> arokux: hollywood uses gimp for their movies
<deasy> arokux, how? open source that's all
<oliv3r> arokux: well they forked it to filmgimp which is now ... i forgot tis name, but still opensource
<deasy> it's not as it hard thing to do
<oliv3r> arokux: REAL software, opensource OR closed, gets licensed b use
<oliv3r> arokux: e.g. a company using your product has to take a license for using it
<oliv3r> arokux: look at red-hat, you have to pay big money to use red-hat inside a company
<arokux> you simply cannot provide this kind of support and documentation quality. take a look at Matlab, for example
<deasy> in multimedia the better exemple of piece of software is Blender
<oliv3r> arokux: take a look at red-hat linux
<deasy> Blender is used in France for do LOT of publicity
<deasy> you can't imagine how much
<oliv3r> if you have a good product, you make companies buy a license to use your prodcut, it can sitll be fully open source
<oliv3r> worst case, dual license, GPL + commercial license
<deasy> or buy support ;)
<arokux> oliv3r, how is red hat open source and I still need to pay for its use? cannot i just build it from source and use it?
<oliv3r> arokux: you can, but you can't ask red-hat for support
<deasy> most case is buy for support
<oliv3r> arokux: but if you, as a use want that, you use cent-os :)
<oliv3r> arokux: but how do you think red-hat became a billion dollar company?
<deasy> arokux, you can, centos is rhel open
<deasy> the sources are available
<deasy> just you have no support
<oliv3r> but as a company, you woul dnever run cent-os
<deasy> when you paid redhat, you get support
<oliv3r> you want to be able to call red-hat and say 'look, i have this problem, fix it'
<arokux> oliv3r, by offering support - that one I know. but they've used software that was developed prior to their existence
<oliv3r> but I don't know the rhel/centos licensing
<deasy> oliv3r, an internet provider here use centos for hosting ;)
<oliv3r> they could very well state 'cooporate users have to pay licensing fee's
<arokux> oliv3r, do you think the could start from scratch with oss?
<deasy> if you don't need support, as you have your internal techies
<oliv3r> deasy: exactly
<oliv3r> arokux: just dual license your prodcut, say 'GPL for private use, for commercial uses inquire by email'
<oliv3r> arokux: IF a company decides to use it anyway, they are just as illegally using your software, as if they would download photoshop
<oliv3r> which is illegal aswell
<Turl> arokux: have a look at asterisk
<deasy> my sentence was wrong
<deasy> CentOS is a build of sources RHEL
<ZetaNeta> How aprox is the price for A31? And how different they are from A31s?
<deasy> oliv3r, most part of rhel is under GPL
<arokux> ZetaNeta, check olimex website, look for components on the left
<ZetaNeta> tnx
<mripard> arokux: seriously, since when linux-sunxi has become the proper mailing list to send mainline patches? Not even CCing the actual maintainers and mailing lists
<Turl> ZetaNeta: and remember than buying direct from china/in bulk is cheaper :p look at aliexpress
<mripard> you will *never* get a patch merged that way.
<Turl> mripard: I think he was just looking for a pre-review to clean up any big issues
<Turl> considering the TODOs and FIXMEs
<mripard> oliv3r: I don't really recall wether the USB pins are muxed or not
<mripard> I think there is at least some of them iirc, but I'm not definitive
<arokux> mripard, yes, Turl is right, if you say it is wrong, then I'll resend.
<mripard> Turl: arokux: well, either the patches are ready to be mainlined, or there not. If they are, then send them to the proper people. If there not, don't claim it is then.
<Turl> mripard: I don't recall anyone claiming so
<ZetaNeta> oliv3r, Would you pay for a "cheaper than EEE PC" netbook, that have 2 motherboards with "Quick Switch" stuff?
<ZetaNeta> I mean, 2 EOMA's in a netbook
<Turl> ZetaNeta: I recall someone doing that
<Turl> they added an arm board inside a notebook and had kind of a switching mechanism
<arokux> mripard, they are ready from my point of view. next is mailing list. I've thought ours ML will be a good pre-mainline mailing list check
<mripard> Turl: well, I don't see anywhere in its mail or IRC ping a mention that it's not usable/has some drawbacks
<ZetaNeta> Turl, You mean the IBM?
<arokux> mripard, do not be angry plz, I'll fix things ppl told me sofar and will post patches to proper mainline lists.
<ZetaNeta> When they done "Dual CPU" thing. That allowed you quickly switch to a lightweight less battery intensive linux
<arokux> mripard, and next patches will go to mainline lists too.
docice has quit [Quit: docice]
<arokux> mripard, or do you want to give me some comment before I sent patches to mainline lists?
<mripard> arokux: I'm not angry at you specifically, it's just a pattern that arose recently, and you're just the last example of it.
<deasy> arokux, thank you for code :p
<arokux> mripard, yes, I remember you complaining. I should say I'm a bit too shy to send to mainline lists directly :)
<mripard> arokux: and since you're the only one that really has a clue about what you've been doing
<deasy> you are shy to get a flame :p
<mripard> the only in depth and meaningful review you'll get will be by the USB maintainers
<deasy> Linus is goind to eat you hehehe
<deasy> going*
<mripard> deasy: honestly, this is just a tale to frighten young kernel developpers before they get to sleep
<arokux> mripard, ok, patches will be at the proper mailing lists tonight.
<mripard> arokux: other than that, wingrime's right, use your real name
<mripard> make it through
<Turl> ZetaNeta: no, I mean some dude that made like an arm board you put inside a certain kind of notebook and made it bootable from that small board or normal computer
<arokux> mripard, there was P.S. - I was going to.
<ZetaNeta> Turl, Canonical?
<mripard> and give a reference to the name of the patch serie you're using
<mripard> arokux: PS?
<Turl> ZetaNeta: no, it was not corporate
<Turl> ZetaNeta: can't find it now
<arokux> mripard, post scriptum in my e-mail.
<mripard> ah, right, sorry then :)
<ZetaNeta> Turl,Artem Kyznecov?
<arokux> mripard, no problem, nobody noticed it :D
<Turl> ZetaNeta: looks like a cracker? dunno :p
<Turl> ZetaNeta: found it!

<ZetaNeta> Exept, they have done it built in :D

<arokux> tgaz, what are those numbers p15?

<soldoKyn> ssvb: after the 2 tweaks (fb0_framebuffer_num, sunxi_fb_mem_reserve) now my Xorg.log seems ok . The results from glmark2 are (a 800x600 window session and a 1280x720 fullscreen one). Are this results as expected or maybe too low (your results on Mele A2000 much higher)?
<soldoKyn> Also I noticed from glmark2 log some errors...also these are expected or I might have done something wrong?
<libv> mapbuffer is an implementation thing
<libv> vertex texture fetch is a hw thing, it is not manadatory by the spec
<libv> the mapbuffer issue should disappear with the free driver, at one point
<libv> the other is never going to get fixed
<ZetaNeta> arokux, Does it have nand on it? Or SD card is the only memory?
<arokux> ZetaNeta, i'm not its designer, lkcl_ is.
<ZetaNeta> :D
<soldoKyn> libv: ok thanks! do you think that my glmark2 results are good?
<arokux> ZetaNeta, so when should we expect the netbook?
<ZetaNeta> arokux, Step 1: Get 2000 euros, which i should get in the end of the year
<ZetaNeta> Step 2: Invest into a 3d printer
<ZetaNeta> Step 3: Finish the design of the netbook
<ZetaNeta> With all the cool features
<arokux> ZetaNeta, why not use online 3D printing service, just to check your idea works. for mass production you can then buy a 3D printer.
<ZetaNeta> Step 4: Realize that this is out of expected price for netbook.
<ZetaNeta> Step 5: Remove half of the features
<ZetaNeta> So.... You probably understood
<ZetaNeta> "It will take a while"
<ssvb> soldoKyn: it gets synchronized with monitor vertical refresh, you can change option "SwapbuffersWait" to "false" in /etc/X11/xorg.conf to run at full speed
FDCX_ has joined #linux-sunxi
<ssvb> soldoKyn: though it's a bit strange that some of the tests are showing FPS as 53 or 55, they all should normally be close to 60
<arokux> ZetaNeta, do you have some design already?
<ZetaNeta> arokux, I got a long long list of ideas to implement
<ZetaNeta> i wonder if its easy to have a Win8 on arm
<ZetaNeta> Becouse if it will support windows. Sells will be much higher
<ZetaNeta> If it will support winCE/win8
<ZetaNeta> Also, i think about doing a kickstarter thing. Becouse there are quite a bunch of guys who "Reinvent LiveUSB drives", and actualy get money there.
<ZetaNeta> And that may "make my dreams come true", and allow me to order "more details", thus making the device cheaper to produce
<ZetaNeta> + A flow of customers!
<ZetaNeta> + Unspent money.......
<ssvb> libv, soldoKyn: nice, running strings on the new mali x11 blobs seems to shows some use of DRI2SwapInterval, which means that probably benchmark programs can be made to run fast even without xorg.conf tweaks
<libv> ssvb: me no likey
<libv> i got the horse spinning btw
<ssvb> older r3p0 mali blobs did not have any references to DRI2SwapInterval
<ZetaNeta> arokux, How do you think, how long a "x86 laptop" sized battery will keep the arm
<ZetaNeta> day, 2? Month?
<arokux> ZetaNeta, just do some calculation
* ZetaNeta can.....

<ssvb> soldoKyn: btw, what kind of x11 desktop environment are you using?
<ssvb> soldoKyn: I'm just afraid that the 53 fps problem might be caused by compositing
ganbold__ has quit [Remote host closed the connection]
<ssvb> soldoKyn: or the xorg config might be actually in /usr/share/X11/xorg.conf.d
<arokux> how is this neat command called that looks for maintainers for the patch?
<soldoKyn> ssvb: with swapbufferswait set to false the results are closer to yours on a10/a13... 113 for 800x600 window and 73 in 1280x720 fullscreen and like mentioned in your readme file some individual test run with more than 200 fps...
<soldoKyn> ssvb: I'm using xfce4 with openbox...
<soldoKyn> ssvb: where I can get the memory clock freq? from dmesg?
<ssvb> soldoKyn: the results look ok for r3p0 mali drivers, r3p2-01rel2 drivers are going to be faster

<soldoKyn> ssvb: I'm happy that the glmark2 performance are good although limited by memory speed!! Thank you for you precious suggestions and for the time spent!
<soldoKyn> libv: thank you too!!
<arokux> Turl, thanks a lot! do you think saying "Based on sunxi-ehci.c" is enough? ppl would ask themselves where this sunxi-ehci.c is... maybe Based should be really omitted?
<ssvb> soldoKyn: there is one more thing to check, you can try "performance" cpufreq govornor instead of "ondemand" (with the gpu benchmark, the cpu is used only sporadically and probably sits on a low clock frequency)
<Turl> arokux: yeah, you can omit that I suppose
<mripard> arokux: I usually just say "Based on code " and the allwinner copyrightt
<ssvb> soldoKyn: this may potentially improve the glmark score a bit
<mripard> it's enough

<arokux> thanks mripard
<sioxs> hi everyone! just got a Android A10-20 v4.2.2 with sun7i ARM7 and have a few issues I can't seem to solve any help would be appreciated setting up the box
<sioxs> it seems the device has group permissions set and I can't figure out how to add the xbmc user to the media_rw group
<buZz> edit /etc/group ?
<sioxs> any device that gets attached can be read but not written to how do i change this behavior?
<sioxs> there is no /etc/group file in this box
<buZz> well then no clue
<sioxs> is it lust a matter of adding the file and adding the content?
<buZz> no!
<buZz> are you even running linux?
<sioxs> I'm not familiar with this platform but know linux somewhat
<sioxs> yes the Android is a linux kernel v 3.3
<buZz> ahhh android
<buZz> i think the /etc folder is in /system somewhere
<buZz> not 100% sure
<buZz> and usually you are not allowed to write to it
<buZz> also, adding users to groups shouldnt be needed on android
<sioxs> a teminal only uses sh but busybox is installed and chown or the like doesn't write the changes as the permissions are set ----rwxr-x
<Mithrian> Anyone having trouble with USB0 in host mode after reboot?
<Mithrian> Seems like it won't detect the device
<Mithrian> you have to remove it and replug it
<sioxs> I looked in the system folder there is a link to the root dir but no group file and i can;t find where the permissions are set for users
<sioxs> yes
<sioxs> tried almost everything including reformatting no luck
<sioxs> every device gets mounted with uid=1000 gid=1023
<techn_> ssvb: It works atleast 340Mhz .. I left there yesterday.. since I was wondering why I got only 1700 points on antutu
<techn_> ssvb: so there might be other things wrong
<sioxs> but users are set uid=1000 gid=1015
<techn_> (mbus??)
<sioxs> ?
<ssvb> techn_: interesting, is it a worse score than with lower mali clock speed?
<techn_> ssvb: I havent benchmarked that yet
<techn_> I'll try to get highest clock first
<ssvb> techn_: the slower speed is actually one of the possible symptoms of gpu failures (the picture freezes for a while, and you get "Mali PP: Hard reset of core Mali_PP0" in dmesg)
<sioxs> buZz I have root access but it still doesn't let me have write access to mounted devices - is there a way to simply add the user to the group?
<sioxs> I know but when things arn't working ssh or installing a terminal usually can solve the problem
<buZz> i have never ever fixed a problem on android with doing anything in terminal
<buZz> nor is this #android-sunxi

<oliv3r> did you know about that?
<libv> upstream adheres to it
<oliv3r> libv: linus disagrees with it :)
<Turl> oliv3r: it is kind of soft, but don't go over 80 on all lines :)
<oliv3r> it should be 80 limit, 90 softlimit, 100 hard limit
<libv> oliv3r: but he is just the tip of the iceberg

<wingrime> libv: better see my patches and I contine hacking tvenc

<wingrime> oliv3r: I have no idea how connect it
Mithrian has joined #linux-sunxi
<wingrime> oliv3r: begin make new kms driver?
<arokux2> mripard, if I select "Kernel low-level debugging functions" the kernel will hang after "Starting kernel...." no matter which sunXi UART I pick 0 or 1.
<oliv3r> wingrime: a LOT of work; but VERY needed
<techn_> ssvb: 456MHz crashed
<oliv3r> video driver probably requires more then 1 person to work on
<wingrime> oliv3r: yes
<oliv3r> wingrime: i did like your video out u-boot proposoal
<wingrime> oliv3r: but I alread see many people who want do sata
<oliv3r> yeah because it's very easy
<wingrime> oliv3r: but no one display driver
<wingrime> oliv3r: but I need wait Turl
<oliv3r> axp might be easier then disp
<wingrime> oliv3r: not sure
<wingrime> oliv3r: gpio, leds, adc, irq contr, regulator driver,
<wingrime> oliv3r: input driver
<oliv3r> we should make a list on wiki, based on memory map
<oliv3r> and then make a priotization order
<oliv3r> tv-decoder has the advantage that its' input
<oliv3r> adc is interesting, we have the LRADC on ML right now
<Turl> nobody wants to do dma? :)
<wingrime> Turl: I can, but without users it useless
<wingrime> Turl: we furstly must have some testable dma users, than do
<oliv3r> Turl: DMA is being done by matt
<oliv3r> i agree with alexsey here
<oliv3r> er wingrime
<oliv3r> have drivers that also work in pio mode; then add dma mode
<ssvb> techn_: hmm, 456MHz is a really high clock speed for mali (A10 and A20 already crashed at 416MHz for me)
<wingrime> oliv3r: firslty we must have pio users , than do dma
<wingrime> oliv3r: can you try make color-full table with legend
<wingrime> oliv3r: about SoC patrts we support in mainline and linux-sunxi
<wingrime> oliv3r: like radeon matrix
<ssvb> techn_: looks like 381MHz might be indeed the realistic clock frequency limit for A13, at least A13 does not seem to be worse than A10/A20, thanks for testing
<Turl> oliv3r: we have emac :)
<wingrime> ssvb: how can you explain diferent clock max with same techprocess?
<Turl> wingrime: luck, not all chips are created equal
<techn_> ssvb: 432Mhz was ok.. but there is no great performance difference between 180Mhz -> 432Mhz :(
<wingrime> Turl: no, cpu have 1080 Ghz normaly
<wingrime> why mali can not?
<wingrime> err
<wingrime> MHz
<Turl> wingrime: heat design?
<wingrime> Turl: no
<oliv3r> Turl: maxime said emac needs a cleanup!
<oliv3r> and we need GMAC!
<oliv3r> wingrime: GEMAC
<wingrime> Turl: i think only about conveer longness
<ssvb> wingrime: I'm not trying to explain anything, I'm collecting data right now to make conclusions later :)
<wingrime> ssvb: thats depend on IC
<ssvb> wingrime: somebody decided that it was a good idea to run mali at 180mhz in a13, I just want to confirm that the chip really can work at a much higher clock frequency
<wingrime> ssvb: marketing
<ssvb> techn_: maybe the memory is way too slow and is becoming the bottleneck, or maybe your benchmark is not a pure gpu test
TheViking has quit [Ping timeout: 250 seconds]
<wingrime> ssvb: a13 cheaper than a10, so a13 must not interfere with more expensive a10, thats means it must be slower
<techn_> that gives boost from 1600points to 1800points
<wingrime> ssvb: if you make a13 too powerfull, you never sell a10
<ssvb> wingrime: I find it hard to believe, most likely it was decided that the low resolution screens do not need fast mali and decided to save battery by running mali at the lower speed
<jelly-home> wingrime: or dissipation numbers
<techn_> ssvb: yes.. tablet runs hotter when clock is higher :p
<jelly-home> imagine that!
<techn_> ssvb: is there clock throlling in r3p2 driver?
<techn_> or does it work
<rz2k> techn_: we dont have mali_utilization_handler implemented
<ssvb> techn_: the odroid sources have some sort of dvfs for mali
<rz2k> mali can report utilization status to function, which should scale freq. accordingly
<techn_> rz2k: nice :)
mcbrick has joined #linux-sunxi
<wingrime> ssvb: most problematic I think, aw use old 55nm still but rockchip use 28nm
<wingrime> ssvb: overheat and , bad tablet battery time
<rz2k> have no idea if we can do that on sunxi, switching pll on the go. exynos has a dedicated video PLL (called VPLL :p) for this purposes
<ssvb> rz2k: switching pll dividers is no good?
<wingrime> hipboi: AW still contine use 55nm ?
<arokux2> oliv3r, are you up to test usb host now? ;)
<ssvb> rz2k: a20 has a dedicated extra pll for mali, but unfortunately not the earlier sunxi chips
<wingrime> ssvb: aw enginers mosly correct use single pll for mali and cedar
<oliv3r> arokux2: my boards are packed up at this moment
<rz2k> needs test, that was all I wanted to say. our clk code might not be ready for this sort of switching right in the middle of something.
<arokux2> oliv3r, so then later tonight?
<wingrime> ssvb: if you want save chip space
<ssvb> rz2k: actually I was a bit horrified when I looked at the allwinner pll frequency switching code, each pll multiplier is implemented as a bitfield and they are updated separately!
rz2k has quit [Read error: Connection reset by peer]
rz2k has joined #linux-sunxi
<ssvb> why on earth could not they just do a proper atomic update of the whole 32-bit pll configuration register in one go?
<rz2k> its allwinner

<wingrime> jemk: do you readed that?
<boycottg00gle> ssvb: ha - thanks! will try

<arokux2> mripard, mm.. not sure. should I?

<Turl> ZetaNeta: you can use kexecboot I guess
<Turl> or Petitboot
<ZetaNeta> Greyish background, icons of availible OS. Thats apple stuff
<jemk> wingrime: the strange vdpauinfo is normal, i didn't implement the query functions yet, so he gets uninitialized random garbage.
<Turl> ZetaNeta: check those two out then

<ZetaNeta> Like order to make them in china?
<ZetaNeta> Because i suddenly choose in the side of china power, instead of "at home" 3d printing
<arokux2> ZetaNeta, I'm sorry, but you really spam here. (check out and ask further questions in #arm-netbook
<arokux2> Turl, can you test usb host for me now/later tonight?

<Turl> ZetaNeta: I doubt you'd even start covering factory tooling with that amount
<Turl> arokux2: on a CB2 I can
<arokux2> Turl, is PLL6 added on A20?
<ZetaNeta> Turl, Well.... What about 2000?
<arokux2> ZetaNeta, do not spam plz
<ZetaNeta> arokux2, Who says about spam?
<arokux2> ZetaNeta, do you have allwinner based board?
<ZetaNeta> Yes
<Turl> arokux2: yes
<ZetaNeta> 2 of em
<arokux2> ZetaNeta, which one?
<ZetaNeta> inet9something
<ZetaNeta> and another which i need to figure out
<arokux2> ZetaNeta, what? what is that?
<ZetaNeta> inet97f-ii
<Turl> ZetaNeta: dunno, ask in the other channel better :p but even if you don't consider tooling it'd be a 20 device run
<ZetaNeta> and another is a A13 based one.
<ZetaNeta> Turl, Ok.

<Turl> arokux2: what do you want me to test?
<arokux2> Turl, usb host, but wait, i'll add bindings to a20 first.....
<Turl> ok
<Turl> arokux2: add bindings for all of them except A31
<arokux2> Turl, all of them = dtsi?
<Turl> arokux2: there's part of the binding on the dtsi, yes, and the muxing goes on the board dts
<arokux2> Turl, so you tell me I should add ehci bindings to all dtsi and all dts for all except of A31 based?
<Turl> arokux2: if they have usb ports, sure :)
<Turl> if they don't, don't :)
<oliv3r> ZetaNeta: the whole problem with touchscreen, well the i2c ones, is that you need many drivers to support all; all need to be matching the display etc, touchscreen, while nice, is hard to support that early in the boot stage. with keys it should be doable
<arokux2> Turl, ok, i'll add to A20 only, i do not know the other hardware really.
<deasy> arokux2, yes
<arokux2> deasy, do you want to help by testing things?
<deasy> maybe :p
<ZetaNeta> oliv3r, ok
<arokux2> deasy, you have cb2, right?

<arokux2> deasy, ok, you don't see to be enthusiastic enough )
<deasy> seems*
<deasy> i'm a bit tired
<deasy> say what to do and i do it

<arokux2> deasy, sorry, it is a long list of things. I've thought you did it once.
<deasy> tomorrow :p
<deasy> i need to sleep
<deasy> prepare it
<Turl> arokux2: ping? :p
<arokux2> Turl, yes
<deasy> oh oh :o sound of mice
<deasy> mouse*
<Turl> arokux2: ETA for node added? :P
<arokux2> Turl, no idea, maybe not tonight even, I've decided to do thorough testing by myself first, but smth wrong with my rootfs......
<Turl> arokux2: ah, ok then :)
<arokux2> Turl, I cannot login into alip rootfs, do you know what can be the problem?
<Turl> dunno, what pw have you tried?
<arokux2> Turl, seems like it creates login on another console...
<Turl> arokux2: you can always boot passing init=/bin/sh and skip all the things
<arokux2> Turl, it worked but bash behaves ugly.. no arrow keys and backspace
<deasy> gn
deasy has quit [Quit: Nom d'un quark, c'est Edmonton !]
<arokux2> Turl, any idea what could be the problem: ?
<Turl> bad inittab?
<arokux2> Turl, any other headless rootfs you can recommend? buildroot works but most of the command are stripped off. there is not libusb -v, for example.
