wandboard quad c1 etnaviv

duperray commented 8 years ago

Hi,

etnaviv driver on 4.5 branch use to work very well on debian stretch, however I tested 4.6 and 4.7, the driver loads but a simple cursor is blinking on the upper left of the screen.

by the way, I had to append -armmp to version.sh because dpkg refused to install the build package if the flavor was wrong.

Thank you so much for providing theses easy to use build scripts.

Cheers

Pierre

hi @duperray

yeah i've fallen behind on my imx etnaviv testing. (v4.5.x was when i was testing it the most)

Double check that you are using:

https://github.com/austriancoder/libdrm

and the newest mesa branch:

https://github.com/etnaviv/mesa/tree/12.0_etnaviv

as i know debian stretch had a newer version of libdrm come down.

Hi,

I was completely wrong,

the stretch debian kernel work perfectly well, I'm using console + xorg there (4.6.3) and your patched 4.7 branch kernel work also very well. Sorry for the noise... I don't know what happened!@#%

for the record, I have libdrm 2.4.68 on debian stretch.

for mesa, I did not test anything (11.2.2 available). As soon as 12.0 will be packaged for stretch, I will try acceleration. But wait a minute, there is no 3d games for arm? does it?

anyway, thank you very much to take time for you last reply.

Cheers,

Pierre PS: you probably own many wandboard but if I can test on debian (as you seems to use ubuntu) for you or just help in anyway in "basic" testing just ask :)

Hi, the packaged kernel can't install on debian, because uboot need the dtbs to be in /usr/lib/linux-image-${uname -r}/ Another point is that dpkg refuse to install the package if you don't provide the correct flavor `-armmp' in the package name (easy workaround is to put BUILD="-armmp" in version.sh). thank you so much for your work

Cheers Pierre

@duperray not sure what your complaining about, if you use debian's u-boot and flash-kernel packages you will have issues with my repo..

Either use the "netinstall" i provide

https://github.com/RobertCNelson/netinstall

or the step by step directions here:

https://eewiki.net/display/linuxonarm/Wandboard

Or you can just wait till Stretch+1 when debian integrates all of this. ;)

Hey robert, I'm not complaining ;) Thanks for the links, I did not realize I had to use a customized netinstall for your armv7-multiplatform repo. I only installed with the jessie installer thru the serial link and later upgraded to stretch. I tested a few of your kernels the 4.5 was a good one for me because it provided video. unfortunately, after switching to the stock debian 4.8 kernel, video broke again. So I tested (I have a wandboard quad rev1c) your 4.8.x, same pb, tryied the 4.9.x, same pb, now using your 4.10.x and TADA, video again :) the only thing is, I have to dpkg -x the builded .deb linux image and manually copy the dtbs in /usr/lib see https://packages.debian.org/stretch/armhf/linux-image-4.8.0-2-armmp/filelist (the official stretch 4.8 kernel put *.dtb in /usr/lib/linux-image-`uname -r') or uboot during installation of the kernel complain about this (uboot, not me ;) How heavily did you change the netinstall? it's completely different project from the debian netinstall? Regards,

Pierre

So the netinstall is just a wrapper around debian's debian-installer..

It provides its own u-boot
provides a mainline kernel (with patches for enablement of devices not support by debian yet)
preseed file with a generic default partition layout
adds repos.rcn-ee.net
neuter's flash-kernel

flash-kernel: this is the pain, unless your board is supported by debian, flash-kernel goes out of it's way to do things "it" want's to do.. So we override the flash-kernel database, this let's us "just" install the linux-image*.deb, and allow a grub inspired script setup the vmlinuz/dtbs in the correct location in the boot directory.

flash-kernel: it's what is forcing "armmp"..

flash-kernel: https://sources.debian.net/src/flash-kernel/3.73/db/all.db/#L1381

Machine: Wandboard i.MX6 Quad Board
Kernel-Flavors: armmp
DTB-Id: imx6q-wandboard.dtb
Boot-Script-Path: /boot/boot.scr
U-Boot-Script-Name: bootscr.wandboard
Required-Packages: u-boot-tools

Now look what we patch in: https://github.com/RobertCNelson/netinstall/blob/master/lib/flash_kernel/all.db#L2460

Machine: Wandboard i.MX6 Quad Board
Method: generic

and here's our linux-image post install:

https://github.com/RobertCNelson/netinstall/blob/master/lib/shared/zz-uenv_txt

in the most generic case, it just updates uname_r in /boot/uEnv.txt, so U-Boot knows what vmlinuz/dtb to load..

Robert, Thx for the explanation, I have a long way to go but I think I will follow your advice and wipe out my mmc and give a go to your netinstall. Hopefully after some learning I could do more useful comments and testing on the wandboard. Thanks again for your time.
