Hello Rebecca,
I am currently working with an evaluation board based on the E3825 chipset. To
evaluate the usage of yocto I have recently checked out your git branch for
valleyisland. So far the image is successfully booting into the core sato
image. Thanks for your great work.
At the moment I am working to support OpenGL in the XServer via mesa. And I
have a local fix for the accelerated graphics driver which is different to
yours in this patch.
It seems for me that the E38 Series uses the i965 mesa driver for 3D
acceleration. With the inclusion of ${XSERVER_IA32_I915} the i915_dri.so is
included in the rootfs. This leads to the following error message in Xorg.0.log:
...

With the inclusion of ${XSERVER_IA32_I965} the i965_dri.so is deployed in an
image. And the GL capabilities seems to be ok following the log in Xorg.0.log:
...

...
It seems to me that the E38 series is supported by the i965_dri.so file despite
that the kernel module for the drm/dri driver is called i915.ko. But maybe I am
missing some point here because I have not tested the OpenGL capabilities yet.
With kind regards

Betreff: [meta-intel] [PATCH 0/2] [Dylan] meta-valleyisland: update README and
machine conf file
From: Chang Rebecca Swee Fun <[email protected]>
Hi everyone,
In this patch series, I have changed the machine conf file to include
${XSERVER_IA32_I915} to the build. This is an urgent fix for meta-valleyisland
as the image built without the fix is using unaccelerated frame buffer driver
to do graphics rendering. The BSP should support i915 accelerated graphics
driver.
Besides, the README of meta-valleyisland has also updated with Yocto Project
Compliance note and HD Audio build note. Customers need to know that, in order
to get HD Audio working, they need to have gstreamer and ffmpeg plugins
installed. And these plugins are provided by adding "commercial" license flags
in local.conf.
Please pull this patch set into meta-intel Dylan branch.
Thanks.
Rebecca
