[SOLVED] AMD radeon VCE support

I faced the good old bug radeon VCE init error (-110) for a long time. Yesterday, I sat down to do something about it. The solution that most people followed is to disable the VCE using options radeon vce=0 in the file /etc/modprobe.d/radeon.conf.

I also looked at the amdgpu driver page on Arch wiki. However, the process of being able to use that driver seems daunting. It seems to me that one needs to build/compile the kernel. Therefore, I don't want to pursue that path if there's no benefit in doing so.

Has anyone here used the amdgpu driver to get around the VCE error? If so, can you please explain the processes you followed?

My GPU:

VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Mars [Radeon HD 8670A/8670M/8750M]
	Subsystem: Hewlett-Packard Company Mars [Radeon HD 8670A/8670M/8750M]
	Kernel driver in use: radeon
	Kernel modules: radeon, amdgpu

Re: [SOLVED] AMD radeon VCE support

Where did you get the idea that you need to build your own kernel? Can you show that text? You might have misunderstood something about it.

Maybe I misunderstood what is written here! Especially this line:

When building or compiling a kernel, CONFIG_DRM_AMDGPU_SI=Y and/or CONFIG_DRM_AMDGPU_CIK=Y should be be set in the config.

Re: [SOLVED] AMD radeon VCE support

The line before that is:

The linux package enables AMDGPU support for cards of the Southern Islands (SI) and Sea Islands (CIK).

The line you quoted is for those building their own kernel.
Edit:
You need to set the module parameters for Sea Islands.

Re: [SOLVED] AMD radeon VCE support

Thanks. I was able to change the driver to amdgpu.
I changed my kernel parameters (/boot/syslinux/syslinux.cfg).

However, amdgpu doesn't provide VCE and UVD support for my GPU. So, I am gonna revert back to the radeon driver and hope that the VCE bug gets fixed.
