00:45 <totopr> hi all

00:46 <totopr> may I ask for support about boot from SDCard on RK3188 ?

00:50 <totopr> i flashed the image http://dl.radxa.com/rock/images/android/radxa_rock_android_kitkat_r2_140911_sdcard.zip on the SD card with sudo dd if=radxa_rock_xxxx_sdcard.img of=/dev/sdx but the tablet just ignored the sdcard and did a normal boot

00:51 <totopr> that image is shipped as sd-bootable

00:51 <totopr> anyone?

09:45 <aep> hi. any idea how to get rk29_wdt working? i.e. watchdog

09:45 <aep> its compiled in, but .probe never gets called for me

09:45 <aep> that thing https://github.com/linux-rockchip/linux-rockchip/blob/mirror/stable-3.0/drivers/watchdog/rk29_wdt.c

10:16 paulk-collins has joined #linux-rockchip

10:34 <naobsd> aep: do you have a entry like this? https://github.com/linux-rockchip/linux-rockchip/blob/mirror/stable-3.0/arch/arm/mach-rk29/board-rk29sdk.c#L1885

10:35 <aep> naobsd: nope. that explains alot

10:35 <aep> let me try adding that

11:03 JohnDoe_71Rus has quit [Quit: KVIrc 4.2.0 Equilibrium http://www.kvirc.net/]

11:31 <aep> naobsd: i dont have any rk29_device*. maybe this is the wrong driver? it's an rk3288

11:33 <aep> actually not even any platform_device

11:34 <aep> and i dont have /mach-rk29 but /mach-rockchip

11:37 <aep> instead the driver calls platform_driver_register

11:43 <aep> apparantly you need to platform_device_register too? i have no idea how this is supposed to work

11:48 <aep> there's a matching thing with interrupts in rk3288.dtsi , i just dont understand how to piece them together

12:29 unfalse has joined #linux-rockchip

12:29 <naobsd> aep: what you mentioned is rk29_wdt.c in stable-3.0 kernel. unless you give right information, no one gives right answer.

12:30 <unfalse> hello

12:30 <unfalse> i had a miniPC UG007b on a Mali 400. i have installed Debian 7.8 on it, but it don't have a video driver.

12:31 <unfalse> can anybody help me to build and install Lima driver? Or any other normal video driver?

12:31 <aep> naobsd: ah yeah. i have no idea which kernel i got. it's a vendor drop

12:31 <aep> let me figure that out first

12:34 <aep> the closest one i could find is https://bitbucket.org/T-Firefly/firefly-rk3288-kernel/

12:34 <aep> its android 3.10

12:35 <aep> https://bitbucket.org/T-Firefly/firefly-rk3288-kernel/src/e5d1ccebdd1f414c691589afa61197e9757702be/arch/arm/boot/dts/rk3288.dtsi?at=master&fileviewer=file-view-default#rk3288.dtsi-206

12:35 <aep> watchdog irq stuff is set here, i think its correct

12:36 <aep> i just dont understand how it fits the driver here: https://bitbucket.org/T-Firefly/firefly-rk3288-kernel/src/e5d1ccebdd1f414c691589afa61197e9757702be/drivers/watchdog/rk29_wdt.c?at=master&fileviewer=file-view-default

12:37 <aep> i think this is the platform init https://bitbucket.org/T-Firefly/firefly-rk3288-kernel/src/e5d1ccebdd1f414c691589afa61197e9757702be/arch/arm/mach-rockchip/rk3288.c?at=master&fileviewer=file-view-default

12:37 <aep> it says 'Flattened Device Tree', so no idea if the dtsi applies now or not

12:38 <unfalse> the problem only is video acceleration not working

12:39 <aep> unfalse: do you have a /dev/mali ?

12:40 <unfalse> aep: no

12:40 <aep> then that's step1. try to figure out how to install the mali kernel driver in your distro

12:40 <aep> it's a module.

12:40 <aep> probably dkms?

12:41 <unfalse> aep: cat /sys/class/display/*HDMI/mode

12:41 <unfalse> aep: 1920x1080p-60

12:41 <naobsd> aep: try to add 'watchdog { status = "okay"; };' in your .dts

12:41 <unfalse> aep: youtube is working as a slideshow

12:41 <aep> naobsd: ah! thanks. gonne try

12:41 <aep> unfalse: get the mali driver first. nothing to do with resolution

12:42 <unfalse> aep: ok

12:42 <naobsd> mali is _3D GPU_, it doesn't give "video acceleration" at all

12:43 <naobsd> mali is not framebuffer device, and is not HDMI controller.

12:44 <aep> hm i always thought some accell feature depend on a working gl driver? dunno

12:45 <aep> will probably help getting it working anyway

12:48 <sjoerd> It depends on what you're accelerating :)

12:48 <sjoerd> 3d rendering will get quite a bit more accelerated if you use the 3d gpu

12:49 <aep> nah like youtube probably uses the new media thingy in chrome which probably uses gl

12:49 <aep> which probably sucks with the software rasterer

12:54 <sjoerd> chrome does accelrated compositing using GL yes

12:54 <aep> looks like it's not as much as i though tho, i just checked

12:55 <aep> should work fine even with zero gl

12:56 <unfalse> aep: one dude adviced me to use debootstrap and build a driver with it using this instructions http://linux-sunxi.org/Mali_binary_driver

12:57 <aep> i have no idea about debian, sorry. but yeah that wiki is really good

12:57 <aep> not sure how much applies for rockchip, but it worked for me on sunxi

12:57 <unfalse> aep: I started to do it, but got an error. For now I don't remember it exactly.

12:59 <unfalse> aep: i think if i give it another try and post a questions here, maybe i proceed further

13:00 <unfalse> aep: *will proceed

13:00 <aep> yeah

13:01 <aep> naobsd: that wasnt it

13:01 <aep> .probe is still not called although init is

13:05 <aep> i wonder if i should disable CONFIG_OF

13:07 ganbold has joined #linux-rockchip

13:11 <aep> the hdmi driver seems structured exactly the same way. just platform_driver_register and then an entry in dtsi that is status: disabled

13:20 <naobsd> aep: check dts too

13:20 <aep> yeah, i think i misunderstood how dts works

13:20 <aep> getting there

13:20 <aep> is there a reason you said watchdog {} instead of &watchdog{} ?

13:20 <aep> that seems to be how the other stuff works

13:21 <naobsd> ah

13:22 <naobsd> just a typo, probably

13:22 <naobsd> please use right form

13:23 <aep> cool thx

13:28 <naobsd> aep: btw which board are you using?

13:29 <aep> naobsd: ugoos ut3s

13:32 <naobsd> aep: ugoos offers source code?

13:32 <aep> it was quite a battle to get it

13:32 <aep> if you want anything out of it i can probably send it

13:32 <naobsd> :)

13:33 ckeepax has joined #linux-rockchip

13:33 <aep> its absurdly broken of course

13:34 <naobsd> I don't have that board so there is no strong reason to get source code for it

13:34 <naobsd> (I sometimes collect such a thing just for collection...)

13:35 <naobsd> it might be useful for mainlining if there is special hack outside of dts ;)

13:35 <aep> i could probably get my customer to send you one just for helping me fix it :D

13:36 <naobsd> currently I only accept something to hack _with spare time_ ;)

13:37 <naobsd> everytime I wish spare time is included in the box I ordered

13:38 <aep> heh

13:39 <naobsd> btw why do you need watchdog?

13:39 <naobsd> I'm not sure it really works even if it can be enabled

13:40 <aep> because the thing is so broken that it hangs often

13:40 <aep> would rather have it reboot

13:40 <aep> you think it won't work?

13:41 <naobsd> no idea, I just feel something strange because it's disabled

13:41 <aep> yeah

13:41 <aep> i'm pretty sure its random tho

13:42 <aep> the amount of code that made no sense in this thing is amazing

13:44 <naobsd> I checked kernel tree in lollipop sdk, but it's disabled :(

13:45 dlezcano has quit [Ping timeout: 240 seconds]

13:46 dlezcano has joined #linux-rockchip

13:47 <naobsd> aep: then, "&watchdog {}" works?

13:47 <aep> no. but i think i broke something

13:47 <aep> still trying

13:47 <aep> android stuff is quite a nuisance

13:49 <naobsd> lately I don't try Android on RK so much... mainly for hardware health check ;)

13:50 <aep> i fix android middleware for a living. usually the kernel just works, except when china. meh

13:50 <naobsd> one of RK3288 board is 24/7 online at home with mainline u-boot/linux ;)

13:52 <aep> yeah that didnt help

13:52 <aep> http://npaste.de/p/GESl

13:53 <naobsd> aep: oh sorry. I guess it's not ready in RK 3.10 kernel tree... :(

13:54 <aep> going to try copying exactly what hdmi does

13:55 <aep> pretty sure its a device tree thing, since .probe never gets called

13:56 <naobsd> if ugoos kernel source is old, you may try more recent kernel from firefly or linux-rockchip.org mirror. it might be stable... (but I cannot promise updated source is stable)

16:44 <aep> any idea where they put that stuff?

16:44 <aep> probably loaded from the bootloader

16:46 <aep> its definatly loaded by uboot on this box. i just dont know from where. or how to change it

17:00 tlwoerner has quit [Quit: Leaving]

17:10 <aep> aha, its in resource.img

22:45 <totopr> hi all

22:46 <totopr> may I ask a question?

22:54 <naobsd> aep: there should be RK official resource_tool on top directory in kernel source tree

22:56 <naobsd> aep: resource.img can be included in boot.img(and resource.img). if your boot.img has 2nd image, it should be resource.img. loader try to use resource.img in boot.img 1st, and if it doesn't exist, loader try to use resource.img flashed in resource partition.
