Summary: xf86-video-msm: make it work on htc-qsd8 devices
Product: Openembedded
Version: org.openembedded.dev
Platform: PC
OS/Version: Linux
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: Devices
AssignedTo: openembedded-commits at lists.openembedded.org
ReportedBy: lukas at htc-linux.org
Blocks: 5448
Project Website:
https://www.codeaurora.org/contribute/projects/xwinp/
Problem:
currently xf86-video-msm is only confirmed to compile on armv6-novfp htcdream
device. htcdream selects patches to remove the neon support and other stuff
from the driver that is actually designed for the cortex-a8 based qualcomm
qsd8xxxx.
Building for the htc-qsd8 htcleo machine in current org.openembedded.dev
revision it fails.
Recipe:
require xorg-driver-video.inc

It seems like it is missing some variables from the msm_fb driver inside the
kernel. Currently the recipe installs parts from it (include/linux/msm_mdp.h,
kgsl_drm.h) . I am not sure if it is taken from the right kernel source as
there are quite some different versions of both, xf86-video-msm and msm_fb
driver..
Maybe for the above error we just need to add an additional header file. I
searched for the missing defines in the current kernel branch for htcleo at
http://linuxtogo.org/cgi-bin/gitweb.cgi?p=groups/mobile-linux/kernel.git;a=shortlog;h=refs/heads/htc-msm-2.6.32
but could not find them.
I guess this means we need to
*pick a different/older version of the xf86-video-msm to match htcleo kernel or
*find correct kernel tree which has the missing defines and try putting the
headers and still use unmodified kernel on device or
*patch the kernel with matching msm_fb version
It might be a good approach to cleanly start over with the recipe for both
machines.
Different kernel versions for the qsd8 devices are available at
https://www.codeaurora.org/gitweb/quic/kernel/
Like I mentioned I have no clue which xf86-video-msm version matches which
drivers/video/msm version. I can't see where this is documented.
On a side note, I tried to compile xf86-video-msm manually outside of OE but it
did not compile. And I am very puzzled about the total lack of information on
kernel in the README
https://www.codeaurora.org/gitweb/quic/xwin/?p=xf86-video-msm.git;a=blob;f=README;h=c38a80e901d0ff033c39ac157cdfb80530b4830a;hb=refs/heads/chromium
As this a bit out of my league I will be happy about any comment.
Best regards,
Lukas
