Enable AMD GPU acceleration on Adnroid-x86 Release 8.1-rc2 source code

[Thella Shyam Kumar]

Hey All,

With the prebuilt image downloaded from Android-x86 8.1-rc2, software rendering is working.
But the release notes says GPU acceleration for Nvidia/Amd/Intel support is present.
This release contains Kernel4.18 LLVM70 Mesa18.2.

What changes I have to do if I want to make GPU acceleration working with the release code?

Regards,
Shyam

Hi Thella,

Please specify your HW and GPU, I recently tried the 8.1-rc2 codebase,

with libdrm 2.4.96 as one of the few changes and it worked for me with SI, Bonaire, Mullins, Tonga, Polaris

What happens if you start in Debug mode and issue the following command? Could you please provide /data/log.txt

modprobe amdgpu

exit

exit

I didn't try the source code with HW rendering yet.
Will try it out today with HWACCEL=1 in BoardConfig.mk

My platform is AMD Ryzen.

Regards,
Shyam

Hi Shyam,

Please clarify better your statements because if you say sw rendering is working,

followed by "what have to do to have it working with HW acceleration?"

the answer is boot iso in either Live CD, Live CD Debug mode or Install,

the HW acceleration is enabled by default.

In case you find any problem, please go straight to the point,

by providing test report (few lines of info) and, when possible, /data/log.txt collected in Debug mode.

Note HWACCEL=1 (which is default) should be set
in kernel cmdline at runtime. No effect to BoardConfig.mk.

My colleague told me Ryzen5 needs kernel 4.19,
while 8.1-rc2 is still using 4.18.
In 8.1-rc2 it just falls back to software rendering.
Your result seems to be consistent with him.

I think Mauro has some kernel 4.19 testing images
that you can try.

Tried 8.1-rc2 source code with 4.19.3 kernel and it is working.

Thank you Mouro and Chih-Wei.
