<lordlod> PietreLinux: you probably need to target a board, rather than a chip. Different systems have the power, video etc. connected in different ways
<lordlod> PietreLinux: Having a look at the way armbian pulls it together will probably help you a lot, it basically does what you are after https://github.com/igorpecovnik/lib
<PietreLinux> I talk to igor occasionally, it is good person, but I do not mean that, I'm talking about an operating system for tablet,
<PietreLinux> for allwinner tablet
<PietreLinux> kernel sunxi not optimiced for tablet, only optimized for a dev board
<PietreLinux> led,sata,ethernet, very modifications in the kernel for run kernel in tablet
<PietreLinux> kernel sunxi only for dev board

<wens> PietreLinux: its just a bunch of volunteers, not affiliated with allwinner
<PietreLinux> I will make tablets running ubuntu desktop, touch, camera, accelerometer, everything, and I will launch a tablet with that system, but I need people to help me in the decision-making process
perr has quit [Ping timeout: 250 seconds]
<PietreLinux> you have created this, I am morally bound to say
<miasma> how do you create the tablets? do you design the hardware
<PietreLinux> hardware and is designed by our friends allwinner us we put another software
<PietreLinux> not android
<PietreLinux> only Linux compiled with libc
<miasma> i see
<miasma> doesn't sound too bad, but there might be some issues with graphics and open source drivers
<miasma> for instance i think these guys disabled the onchip gpu https://www.crowdsupply.com/eoma68/micro-desktop
<miasma> our friends at allwinner & arm holdings don't want people to use their hardware

<PietreLinux> Although for reasons I do not know you are a very closed community, only in English and with the knowledge and drabs, my amigps of Brazil, Indonesia, India, France, Peru, Argentina, Mexico, would like a tablet with linux inside, no matter if the great sound does not work or that you can not see video in 4K
<PietreLinux> the dev board are fine, but were designed to test apps on android, we now have the opportunity to create tablets with linux

<plaes> wens: don't you want to use SUN4I_CODEC_ADC_ACTL_UNKxxx for those?
<beeble> assuming your kernel config has gadget configured via configfs on CONFIG_USB_CONFIGFS
<wens> plaes: it doesn't really help
<plaes> then you can later grep for _UNK stuff
<wens> beeble: nah, mine is fixed function
<wens> beeble: and it works fine on the a23 :/
<wens> but gives "VBUS_ERROR in a_wait_vrise (80, <SessEnd), retry #3, port1 00080108" on the A31

<oliv3r> olimex has released a new lime2 board revision with a changed PHY. They changed the troublesome RTL8211CL with an RTL8211E. Obviously we want a single u-boot for all lime2 boards, as it would get quickly to confusing
<oliv3r> the problem is, the 8211E on the lime2 needs TX_DELAY=2 rathr then TX_DELAY=0, which is used on all other lime2's
<oliv3r> is there some generic way to fix this?
<oliv3r> my first (noteably wrong) method would be to do check a board.c for lime2, and if the PHY is rtl8211e set TX_DELAY=2
<oliv3r> I think the quick fix may be to just always use Tx_delay, which reduces the performance slightly on older boards ...
<oliv3r> hm we do already have board/sunxi/gmac.c where this delay is set ...
<oliv3r> so it's not a PHY thing, but a configuration of the PHY on the MAC side
whaf has joined #linux-sunxi

IgorPec has quit [Quit: Nettalk6 - www.ntalk.de]
<apritzel> oliv3r: isn't the TX delay in the DT?
<apritzel> oliv3r: anyway a slight decrease in network performance sounds feasible for U-Boot
<wens> apritzel: bad design decision :(
<apritzel> wens: ah, that's the GMAC

<oliv3r> apritzel: i don't think the kernel fully reinits the mac
<oliv3r> hence why we do it in u-boot
<oliv3r> i on' tknow how big the inpact is yet however
<wens> oliv3r: the delay settings is in the clock controller, not the gmac
<mripard> apritzel: having it in the DT wouldn't change anything, it would just move the problem
tkaiser has quit [Ping timeout: 260 seconds]
<oliv3r> inu= u-boot?
<apritzel> mripard: sure, I was just wondering if a separate DT would solve this magically
<oliv3r> wens: i see it applied in boards/sunxi/gmac
<mripard> wens: do you know if some autodetection of the delay could work ?
<wens> oliv3r: i meant the registers
<wens> mripard: if you put the phy into loopback, then maybe?
jski has joined #linux-sunxi
kaspter has joined #linux-sunxi
<oliv3r> sounds reasonable, send data out the mac, over the rgmii, loop it in the mac, and it goes back; devide by /2 profit
<oliv3r> but currently, we have an tx delay, not an rx delay, though i guess that doesn't matter over the wire, we never know when something arrives, ina loopback setup it might matter; then again, these traces generally are parallel
<oliv3r> wens: ah indeed, ccm->gmac_clk; so it's the mac clock stuff; do we change that from the u-boot init in linux atm?
<wens> linux doesn't touch it

<jski> build a production friendly minimal system with basic functionality. in the past have always just built u-boot, kernel and used gentoo but was considering other distro's
<buZz> jski: just stick to buildroot , no need to hipster up
<buZz> buildroot2 is now also coming around
<jski> I can't see the point either
<buZz> re: yocto
tkaiser has joined #linux-sunxi
<buZz> i bet your new dev just doesnt know what's around
<plaes> or debian
<jski> I use arch on pc but will have problems with systemd if on not mainline kernel
<buZz> i use devuan
<buZz> cause i dont like poetering
<jski> gentoo has always been good in the past because I can rebuild all the source so very useful in the future
<jski> either that or I have to make our own repo for full system upgrades
<plaes> jski: why do you need mainline for?
<buZz> :D
<buZz> emerge -E world, daily
<jski> don't need.. just need :P
<jski> have used gentoo on our production boards for years now and has been handy just rebuilding in an arm chroot, should work on 3.4 kernel...
<beeble> yocto isn't that bad but no real reason to switch if you have already another build system in-house
<jski> I guess there is no need to strip the system down to busybox size these days when we have so much storage on embedded devices
<jski> a minimal rootfs plus packaged minus man pages is good enough
<beeble> busybox is nice for having a single binary. makes building a initramfs for examples easy
<Wizzup> we do the same with gentoo @ work
<Wizzup> but we stripped a bit more than just manpages
<Wizzup> jski: do you make thosw images into a squashfs?
<jski> same gone down to this sorta size https://bpaste.net/show/1de7cb3dd70b
<jski> no ext4
JohnDoe_71Rus has quit [Quit: Miranda IM! Smaller, Faster, Easier. http://miranda-im.org]
<Wizzup> jski: right, we do this and store it on sd cards, and from there the gentoo systems do binpkg updates
<Wizzup> probleem is that sd cards are flaky, and all systems are distributed/remote
<Wizzup> so I'm planning to generate a minroot and squashfs that, and just send new squashfs'es
<jski> I have rootfs on eMMC and data storage on microSD
<jski> cortex A8 with kernel 3.0.8 running gentoo armv7l
<Wizzup> how do you update?
<Wizzup> btw on mobile,but later I'm interested to share experiences :)
<jski> the same rootfs now running on my a20 with kernel 4.8.1

<jski> https://wiki.gentoo.org/wiki/Orange_Pi_PC/Quick_Start suggests to used the armv7a_hardfp on the Orange Pi PC
<NiteHawk> i was about to ask, what's missing when using armv7a?
gianMOD has quit [Ping timeout: 260 seconds]
<tkaiser> jski: That's crazy, Gentoo users still fry their H3 boards relying on overvolted overclocker settings.
<jski> oh I see armv8 only adds optional 64bit
<jski> is they why they still have arm64 in experimental? :P
<jski> that why* :/
<apritzel> jski: both 64-bit and 32-bit are optional in ARMv8 ;-)
<apritzel> of course not both at the same time
<jski> yes did not realise that :)
gianMOD has joined #linux-sunxi
<apritzel> but you can have an implementation that only runs AArch64 (Cavium) or only AArch32 (Cortex-A32), while many do both (Cortex-A53, for instance)

<ssvb> either way, gentoo is mostly all about the userland, and one is free to use any kernel with it :-)
<ssvb> and the systemd cancer is still optional there
<jski> yes
<jski> prefered until it is mainline stable
tkaiser has quit [Ping timeout: 244 seconds]
<jski> ssvb: orange pi running stable?
<jski> have ordered the pi pc plus and plus 2
<ssvb> it depends on what you are running on it
<jski> web server and mysql
apritzel has joined #linux-sunxi
<ssvb> btw, the Orange Pi PC is a 32-bit board, it does not support aarch64
<lamer14781880248> jski: Plus 2 is the worst choice, way too expensive, less IO bandwidth and ultra slow USB-to-SATA bridge. Plus 2E is the far better choice.
<ssvb> there will be probably Allwinner H5 based Orange Pi boards soon, and they will be 64-bit
<lamer14781880248> ssvb: Orange Pi PC 2 with H5 will start to sell soon.

<jski> tkaiser: how slow?
<tkaiser> jski: GL830 is ultra slow, 15 MB/s sequential write, 30 MB/s sequential read, no UASP and also good for data corruption.

<tkaiser> apritzel: Yeah, realized it only after uploading :)
<nove> ssvb, about yesterday qemu + tracing, this is what was done http://dl.linux-sunxi.org/users/nove/dtv.png, but i am also in agreement in the question of time as it would be much more useful if the tracing was from real hardware
<tkaiser> jski: If you look forward I would try to get my hands on a R40 device, the only one known today is called 'Banana Pi M2 Ultra'. R40 is more or less a H3 but lacking the 3rd USB host port and replacing it with native SATA.

<tkaiser> ssvb: No idea, at least on OPi Zero it's optional (not populated) ATM. PC 2 sales should start soon and then we'll know.
<tkaiser> nikre: Are you refering to R40?
<nikre> the new opi 64bit
<KotCzarny> 64bit is overrated
<tkaiser> nikre: You mean H5? Given that's more ore less a H3 with different CPU cores performance should be the same as with H3 now.
<nikre> what is the catch about it? 10bit 4k?
<tkaiser> nikre: It's deca-core!!1!11!! Since deca-core Mali450. Also it's said to have better video decoding support and other stuff I don't care about.
<tkaiser> Sorry, hexa-core Mali450
<KotCzarny> mali 450 should be at least +50 better than mali 400, right?
<ssvb> tkaiser: A53 is a little bit faster than A7 though
<apritzel> KotCzarny: 50 more GPL violations, probably
<tkaiser> ssvb: Sure, but this won't affect USB disk access :)
<KotCzarny> ssvb: how git is little bit? in rough percent
<KotCzarny> s/git/big/
<ssvb> tkaiser: yeah, and we have some good chances to use the hikey mali blobs from http://malideveloper.arm.com/resources/drivers/arm-mali-utgard-gpu-user-space-drivers on it :-)
<ssvb> KotCzarny: depends on your software, for example NEON is twice wider in A53 and you may get twice more performance per MHz on some workloads
<KotCzarny> ssvb, is it theoretical or did you check it?
<ssvb> KotCzarny: for the other workloads the performance will be roughly the same per MHz
<ssvb> KotCzarny: yes, A53 is much faster for software rendered 2D graphics, unless you are limited by the memory bandwidth
<ssvb> KotCzarny: and yeah, memory bandwidth is never good enough for 2D graphics
<tkaiser> KotCzarny: Two benchmark numbers comparing H3 and H5 (assuming it's the same CPU-wise as A64): https://github.com/longsleep/build-pine64-image/pull/3#issuecomment-196267397
<KotCzarny> not bad
<KotCzarny> i wonder how much faster arm cores will have to get to make firefox run comfortably
<ssvb> tkaiser: thanks! linpack is a nice example of a 2x neon performance advantage
<KotCzarny> umkay, time to get back to my lovely bpi-r1
<tkaiser> KotCzarny: if you calculate prime numbers for a living (as does sysbench --cpu) then H5/A64 is 15 times faster than H3.
<KotCzarny> anyone doing computations for a living wouldnt use arm
<KotCzarny> not yet
<tkaiser> KotCzarny: Firefox is a database hammering your storage. Get ODROID-C2 with super fast eMMC and it flies.
<KotCzarny> tkaiser, i shall try moving .profile to tmpfs and check
<KotCzarny> for me even opening new window is a bit painful on h3
<KotCzarny> which is a pity, because comparably (per watt used) system (thinkpad x40/x60) is much snappier
<tkaiser> KotCzarny: Simply browse and run iotop. It's just insane. You have to tweak Firefox or Chromium settings regarding IO when running from SD cards.

<AneoX> Hi! Iam trying to boot A20 from emmc, but sunxi_mmc driver in mainline u-boot fails, anyone can help?
<AneoX> Some info http://lists.denx.de/pipermail/u-boot/2016-November/271760.html http://lists.denx.de/pipermail/u-boot/2016-November/271818.html Replace emmc to sd card works like a charm, but with emmc not success((((

<apritzel> AneoX: which kernel? mainline or 3.ancient Allwinner?
The_Loko has quit [Remote host closed the connection]
<AneoX> apritzel: with any, problem in u-boot, not in kernel
<apritzel> I was just wondering about the MMC driver in the kernel which worked
gianMOD has joined #linux-sunxi
<apritzel> it would be a different story if it was only the BSP driver
jstein_ has joined #linux-sunxi
<apritzel> in fact I have the opposite problem: works in U-Boot, fails in the kernel
<AneoX> Boot kernel from sd on sdc0 lines, sunxi-kernel init emmc on sdc2 well, in 4 bit mode

<apritzel> AneoX: can you check the actual clock rate in the kernel?
<apritzel> /sys/kernel/debug/clk/clk_summary
<AneoX> in cat /sys/kernel/debug/mmc0/ios: clock:..52000000 Hz timing spec:.1 (mmc high-speed)
<apritzel> AneoX: and you are sure it's SDC2? The two A20 boards with eMMC support in U-Boot use SDC3, apparently
<apritzel> maybe there is something hardcoded to that port for the A20?
Mr__Anderson has joined #linux-sunxi
<AneoX> i have no success with sdc3 lines, dont know why. Just switch to sdc2, and it works
<apritzel> so you are connected to PC6 - PC11? Just wanted to check
<AneoX> yes
<apritzel> the kernel reads the info from the device tree, but U-Boot has this hardcoded
<apritzel> so I was wondering if anyone ever tried an eMMC on SDC2 on an A20
<AneoX> i use sunxi kernel with script.bin, my mainline u-boot not working with emmc, it fails to switch 4-bit mode and fails to read data
<AneoX> which u-boot can boot from emmc on A20?
<apritzel> Apparently mainline U-Boot should support eMMC boot on two Olimex boards
<apritzel> but they use SDC3
<AneoX> i have SD on sdc0, emmc on sdc2. If boot from SD, kernel well work with both flash.But if tries to boot from emmc, u-boot fails. I gave tried emmc on sdc0 and sdc2, not success. U-boot works if i try SD on sdc0 or sdc2, both works

<AneoX> Tried on 3 boards, A20-marsboard, Cubieboard2 and my custom
* apritzel wonders if U-Boot sets up the right clocks
<AneoX> u-boot seems set 52000000 Hz, but fails to switch to 4-bit width bus and read data. If boot to u-biit from sd, mmc list shows both cards, sd and emmc. mmc info shows correct values for emmc, but mmc part fails on emmc and works on sd. U-boot return mmc_load_image_raw_sector: mmc block read error when tried to boot from emmc
<apritzel> mmh, the clocks seem to be right
<apritzel> so have you tried the latest mainline kernel? 4.9-rc1
<apritzel> or -rc3
<apritzel> there were some MMC changes in that release for the A20
<AneoX> no, i have not problem with kernel, mine works well if u-boot boot kernel)
<AneoX> do you tried to boot from emmc on a20?
<apritzel> AneoX: I don't have an A20 board with eMMC
<AneoX> (
<apritzel> only A64
<apritzel> so you changed the .fex file for the sunxi kernel?
<AneoX> seems like this bug in u-boot on sun7i driver
<apritzel> I was wondering if this was just a config issue in U-Boot
<AneoX> in fex i have just [mmc2_para] sdc_used = 1
<AneoX> i cant find this issue in U-Boot for a month(

<apritzel> AneoX: do you have a clue which voltage the kernel uses?
Mr__Anderson has quit [Remote host closed the connection]
<AneoX> vdd:..7 (1.65 - 1.95 V)
<apritzel> AneoX: oh, so it's a 1.8V eMMC?
<apritzel> U-Boot hardcodes the voltage to 3.3 V
<AneoX> no, emmc powered by 3.3v
<AneoX> vdd:..7 (1.65 - 1.95 V) it from /sys/kernel/debug/mmc0/ios
<AneoX> dont know which voltage in u-boot
<apritzel> which looks like the kernel negotiates 1.8V with the eMMC
<apritzel> also shouldn't it be .../mmc2/ios
<apritzel> ?
<AneoX> kernel give emmc higher priority, looks like
<apritzel> can you dump the whole file? for both interfaces?
<AneoX> cat /sys/kernel/debug/mmc0/ios clock:..52000000 Hz vdd:..7 (1.65 - 1.95 V) bus mode:.2 (push-pull) chip select:.0 (don't care) power mode:.2 (on) bus width:.2 (4 bits) timing spec:.1 (mmc high-speed)

<apritzel> and see what that tells you about the configuration
lerc has joined #linux-sunxi
<apritzel> AneoX: I think it's worth to chase this voltage setting in U-Boot
<apritzel> the eMMC works on the A64 in U-Boot, but my eMMC reports "vdd: 21 (3.3 ~ 3.4 V)"
<apritzel> which matches U-Boot's config
<AneoX> A20-OLinuXino-Lime_defconfig
<AneoX> i use
