<oliv3r> got a VERY positive mail from EVA! they will share the A23 user manual with the community
<oliv3r> and stuff will be requested by UPPER management, so lets see how that goes
<oliv3r> IMG they still use as it is more powerfull then mali (mali 400 sure)
<oliv3r> and they 'hope' powervr become more OS friendly (right)
<oliv3r> mripard: yeah If time permits, as am I; u-boot is 'small' enough to comprehend
<oliv3r> i've got a few fixes/patches that i'm working on; but ... time, time time time
<oliv3r> but lets hope I can get sunxi used here at my new job soon
<oliv3r> that means more support :D

<oliv3r> libv: well she did reveal, that she's not allowed to reveal yet, about new MALI based SoC
<oliv3r> which we kinda new
<oliv3r> libv: look at it this way, their high-end cores will be IMG (for now, until samsung shows them that the newer mali's kick ass)
<oliv3r> but the mid-low end range, what's most interesting to us anyway, will likly remain to be mali :)
<wens> plaes: yeah they did it faster than STi :p
<wens> oliv3r: did you ask for A80 optimus board?
<oliv3r> yeah said we'd be intrested as a community

<gzamboni> let me check here CaptHindsight , thnanks
<gzamboni> CaptHindsight, it seems to be much more complicated to control tho
<Montjoie> hello, can I control a fan with GPIO on a cubieboard ?
<mripard> Montjoie: usually, a PWM is more fit for that
<gzamboni> sup mripard, are you continuing the dma stuff ? i didnt have time yet to continue with the sun4i
<mripard> gzamboni: yeah, I'm still working on it
<mripard> I'm stuck with mem2dev transfers though...
<Montjoie> mripard, does cubieboard2 have a PWM, by GPIO I meant the external output pin
<gzamboni> Do you plan to unify the A10/A20 inside the same driver ?
<gzamboni> i saw you posted they have some similarities at the sunxi wiki
<gzamboni> Montjoie, cant you do pwm using a regular gpio by software ?
<gzamboni> i never used pwm on linux
<mripard> Montjoie: the PWM are exported on a few pins, I don't know wether they are usable or not on the cubie2
<mripard> gzamboni: unify what?
<Turl> I don't think a gpio would provide enough current to run a fan
<CaptHindsight> gzamboni: linuxcnc has kinematics for delta robots
<gzamboni> do you think we will be able to use the same driver to A31,A23,A10 and A20 ?
<mripard> gzamboni: for the DMA ? nope
<mripard> A31 is pretty different
<mripard> A23 has the same controller though
<mripard> but sun4i, sun5i, and sun7i should be able to have a common driver too
<wens> what's the difference between normal and dedicated DMA in A10/A20?
<CaptHindsight> Montjoie: depends on how the fan is connected to the cubie, the IO pins themselves don't drive much current if that what you mean
<gzamboni> CaptHindsight, never used linuxcnc, i read it some time ago, seems to be a good software
<Montjoie> I just see a sunxi-pwm driver, it seems to use the lcd output
<mripard> wens: as far as i understood, only one channel can be active at a time
<wens> Montjoie: there's a PWM controller, with PWM outputs muxed on some pins
<mripard> with dedicated DMA, you have all the 8 channels that are usable in parallel
<mripard> Montjoie: a very common use for PWM are backlights :)
<wens> mripard: so 8 channel dedicated DMA capable of dev2dev would be quite complicated hardware-wise
<CaptHindsight> gzamboni: we are using an FPGA with the A20 to control all types of cnc machines
<gzamboni> :) nice, i never played with FPGA, my brother is working with a project using a xilinx
<CaptHindsight> I'm surprised that there isn't a A20+FPGA board already. I'm tempted to float a deign around China
<CaptHindsight> gzamboni: linuxcnc controls it all
<CaptHindsight> deign/design
<gzamboni> i would buy one :)
<mripard> wens: yep, but the A31 has 16 channels, and only in "dedicated" mode
<mripard> so it seems doable :)

<gzamboni> CaptHindsight, is it a project you're on for a company ? are you selling out this cnc controller ?
<CaptHindsight> gzamboni: Linuxcnc + cubie + an FPGA expansion board, Mesa Electronics might sell the fpga board
<CaptHindsight> they make several already, in fact you could use any allwinner board with ethernet and use that to connect to an fpga for RT machine control
<gzamboni> whats the programming language for FPGAs ?
<CaptHindsight> the fpga vendors have their own tools for programming, but you can use RTL, VHDL or Verilog
<CaptHindsight> open cores has lots of GPL logic blocks and peripherals as well
<CaptHindsight> you can find stepper motor and servo controls in the open as well
<CaptHindsight> we're using SPI and some GPIO to connect the FPGA to the cubie2 right now
<CaptHindsight> I'm tempted to make a allwinner + fpga + motor driver board and let it be copied in China for $50, just to keep the price down
merbanan has joined #linux-sunxi
<CaptHindsight> gzamboni: https://tinyurl.com/m3kjjeb this with an A20 and FPGA could be $50
<gzamboni> what about cheap cnc machines =P what kind of cncs do you have ?
<CaptHindsight> gzamboni: http://imagebin.org/294446 you mean like this?
<gzamboni> this one should costs a fortune
hansg has joined #linux-sunxi
<CaptHindsight> you can find them on ebay and craigs for a few $K
<CaptHindsight> they usually just need a new controller
<CaptHindsight> a cnc machine builder doesn't care so much about allwinner + linuxcnc, but small appliances like 3d printers, routers and mills can benefit from lower BOM cost and smaller size
rz2k has quit [Remote host closed the connection]
<Turl> hey hansg :)
<CaptHindsight> and those were on old ARM9 single core SOC's
<CaptHindsight> the user interface had to be on a separate PC over ethernet
<CaptHindsight> we can play HD video or game and machine on an A20

bsdfox has quit [Ping timeout: 245 seconds]
<CaptHindsight> if allwinner added a servo PID block and a hardware stepper only buffers and drivers would be needed

<CaptHindsight> sorry, am3358 http://www.ti.com/product/am3358
<gzamboni> what is the motor control thing there is in the AW datasheet ?
<gzamboni> its the pwm ?
<CaptHindsight> what section of the manual?
<gzamboni> let me check
<CaptHindsight> the A20?
<gzamboni> A10 and A20
<gzamboni> i remember seeing it somewhere
<CaptHindsight> there is PWM but I'm wondering what you found
<gzamboni> i cant find it anymore, but i remember i did see something about in a drawing or something, but it should be like the GPS and other things they say they have but without any drivers.
<CaptHindsight> yeah, might be hidden in there
<CaptHindsight> if we knew where they get their ip blocks it wouldn't hurt
<CaptHindsight> gzamboni: if you find it, please post it
<CaptHindsight> maybe we can turn it on
<gzamboni> i can't even find anymore where i did see it
<CaptHindsight> mrnuke: is coreboot for A20 in the works? Thanks for the A10 port!
<CaptHindsight> gzamboni: some of the boards mention motor control like the http://www.merrii.com/en/detail.asp?id=149
<CaptHindsight> but I think they either are just cutting and pasting specs or refer to PWM
<CaptHindsight> or maybe the small vibration motors
mrnuke has quit [Ping timeout: 252 seconds]
<gzamboni> i think i saw a motor control mention but it was refering to the pwm
<gzamboni> but i supose it should exists small spi/i2c CIs for that, no ?

<paulk-collins> ok
<paulk-collins> any support from linux-sunxi for it?
<paulk-collins> I mean, by any luck, would it work by just building sun5i or so?
<nove> paulk-collins: the hardware blocks are similar to a31
<memleak> Is there a good reason to use arch/arm/boot/dts instead of Makefile.boot ? Makefile.boot is a lot easier to understand.
<paulk-collins> nove, mmh ok
<paulk-collins> so no-go for now
<ccaione> memleak: ???
<nove> nobody tried, so yes
<memleak> ccaione, ?
<nove> paulk-collins: also by the allwinner roadmap (has version numbers), A80 is also different
<Turl> memleak: what's Makefile.boot?
<ccaione> memleak: better if you read about dts :)
<paulk-collins> ok
<memleak> arch/arm/boot/dts is the new devicetree method that increases LoC footprint and complexity IMO
<memleak> ccaione, yeah maybe :P
<Turl> memleak: there's no more old style platforms accepted on linux
<Turl> you should read up on multiplatform and DT :)
<memleak> but there is no entry in dts for sun7i or sunxi..
<ccaione> memleak: look at mainline
<Turl> sun4/5/6/7i all there
<memleak> im talking about sunxi-3.4 branch
<Turl> memleak: 3.4 is based on allwinner's codebase
<Turl> using the old style
<memleak> in theory would it be possible to copypasta dts code from mainline into 3.4 branch?
<Turl> no
<memleak> ok.
<Turl> 3.4 uses allwinner's fex to configure stuff
<memleak> ah ok so fex is their drop in replacement for dts?
<Turl> kind of
<memleak> ok that makes a lot more sense thanks Turl
<Turl> so you get an idea of what fex looks like
<memleak> oh CPU frequency stuff goes there!?

Seppoz has joined #linux-sunxi
<memleak> dvfs_table... if i wanted the CPU to always run at 1 GHz at all times, can i set min_freq to max_freq with lv1_count at 5?
<memleak> the kernel configuration im using does not use CPU frequency scaling or power management (suspend, APM emulation, CPU idle, etc)
<memleak> and i would like my board to run at max speed all the time.
<memleak> cat /proc/cpuinfo not showing my the current CPU speed makes it difficult to verify it's current speed...
shineworld has left #linux-sunxi ["Leaving"]
<memleak> i'm using cubieboard2 for RT only anyway
<memleak> not concerned about power savings at all
<Turl> memleak: enable the performance governor and that's it
<Turl> you don't need to touch the fex
<Turl> or just disable the cpufreq system entirely
<memleak> disable cpufreq makes it run at full speed? i just couldn't verify this because cat /proc/cpuinfo does not tell me
<Turl> memleak: BogoMIPS should give you a rough idea
<memleak> heh!
<Turl> (yeah, they're bogus and you shouldn't rely on them)
<memleak> what exactly is broken in the first place does not allow MHz to hit /proc/cpuinfo?
<memleak> is it a kernel or fex bug?
<memleak> i'd like to fix that..
<Turl> memleak: no ARM system that I know of shows MHz on cpuinfo
<Turl> so it's not a bug, it's a feature :)
<memleak> ah...
<Turl> MIPS systems don't show them either
<memleak> now i feel really dumb
<Turl> there's no reason to feel that way
<memleak> how sure are you that disabling all cpu freq settings will make the CPU run at highest setting? i know some VIA boards that without performance governor, it will never hit highest frequency.
FDCX_ has joined #linux-sunxi
<Turl> memleak: well, if you don't touch it it'll run as fast as it was on uboot
<Turl> and I believe that's max freq
<memleak> oh ok!
<Turl> you can always just enable performance governor if you like it better :)
<lioka> memleak: cat /sys/devices/system/cpu/cpu?/cpufreq/cpuinfo_cur_freq
<Turl> lioka: he disabled cpufreq on purpose
<lioka> ah
<CaptHindsight> ok, so u-boot inits it at max freq and then fex starts to govern speed
<Turl> fex doesn't do anything, it's just a config file
<memleak> well Turl with your suggestion on BogoMIPS i guess i could compare the BogoMIPS with performance gov then without any CPU freq stepping in kernel and see the difference.
<Turl> memleak: that would be ok
<Turl> memleak: you could run some real benchmark too and compare results
Fusing has joined #linux-sunxi
<memleak> Unigine Heaven benchmark for Linux seems real enough
<memleak> thanks Turl for all the help!
<Turl> anytime
<Turl> but why would you run a gpu intensive benchmark to test a RTOS system?
<CaptHindsight> memory bus load
<Turl> interesting use
<CaptHindsight> or just use Stress
<CaptHindsight> all depends
<Turl> although I like tinymembench a lot
<CaptHindsight> on x86 the biggest hit we see to RT performance is starting up a browser and streaming flash
<CaptHindsight> large memory allocations tend to bump IRQ latency times
<CaptHindsight> thats with SMI, ACPI, APM and any speed stepping turned off
<CaptHindsight> ARM doesn't have the same train wrecks to deal with, but cpu freq changes based on cpu load is something you want off for max RT performance
<Turl> ah, so you run desktop workloads on RT systems
<Turl> I was thinking in embedded RT

<CaptHindsight> Turl: just for testing, the typical RT app is linuxcnc controlling a cnc machine
<Turl> memleak: the mali drivers from malidevelopers don't bring board configs as far as I recall

<randomblame> I have a big fat problem with working on this allwinner tablet - there is no boot to recovery via adb so if I mess up a boot.img or recovery.img I have to reboot to windows and reflash the tab via livesuit and it's taking for freaking ever
<randomblame> I miss fastboot so much
<Turl> randomblame: heh, on most you can boot to android recovery with a key
<Turl> or you know, you can boot a sd card and fix it :)
<randomblame> no key combo here
<randomblame> actually that's not a bad idea
<nove> randomblame: last i heard livesuit could create a usd card to flash the device
<Turl> you can even make a android recovery sd card if you like adb :p

<randomblame> guess I need to find a stack of kernel source that acatualy boots and change cmdline
<randomblame> I thought they added fastboot to uboot a long time ago

<Turl> randomblame: the allwinner uboot has fastboot
<Turl> but it was pretty broken when I tried
<randomblame> aw I'd probably need a serial rig to even talk to uboot on this thing anyhow
<randomblame> reboot recovery from shell doesn't work but adb reboot recovery from the computer does
<randomblame> that's a kernel issue isn't it?
<randomblame> if I could just fix that one problem I'd be able to work around most of my other issues
<Turl> randomblame: are you running reboot recovery as root?
<randomblame> tried both
<randomblame> this thing is running 3.4.39 and is sourceless I haven't managed to get a build of sunxi-3.4 to boot
<Turl> randomblame: from what I recall, you just needed to write stuff to the misc partition, you may be able to do it manually
sehraf has joined #linux-sunxi
<Turl> triple check the partition though

<randomblame> ooh
<randomblame> ty
<randomblame> yep /misc is not mounting

<randomblame> well it exists at least

<randomblame> strange that the a20 and a23 sdks don't have that setrecovery source
<randomblame> maybe it's unneeded? I modified it to match my devices partition layout and I'll try it at least

<Turl> randomblame: setrecovery is not from allwinner
<randomblame> makes sense
<randomblame> what does not make sense is their love of live suite and windows
<Turl> randomblame: it makes sense if you consider factories having to flash hundreds of freshly built tabs :)
<randomblame> every other vendor has figured it out somehow :D
<Turl> randomblame: they all do it that way
<randomblame> aha it looks like setrecovery worked
<randomblame> managed to reboot to bootloader - though fastboot seems to be disabled and it's just sitting there helpless
<randomblame> thanks turl now I can reboot to recovery from a bad boot.img
<randomblame> well mostly
<randomblame> long as I have shell
