Phoronix: A Fresh Kernel Spin For Those Wanting To Use RX Vega On Linux Or AMDGPU DC

For those running Ubuntu/Debian and wanting a kernel with the very latest AMDGPU DRM support along with the very bleeding edge DC display code patches, I've done a fresh spin today in preparation for my latest RadeonSI/RADV Vega benchmarking...

Do you think you can provide kernel headers?

Are you asking out of personal interest? If so, happy to upload them for you. Right now that system is running some tests but as soon as that current round of benchmarking finishes up, can get them uploaded.

Oh, never mind... I was just asking in case somebody has DKMS modules and wants to use your kernel permanently...

This doesn't actually work with Freesync right? Freesync only works if the usermode driver supports it but only the AMDGPU-PRO usermode driver supports it, and that only works properly with AMDGPU-PRO kernel modules?

Freesync support is broken apparently, and has been for quite a while.

I'd like em.
I'm running Vega and I'm impressed and I'll try your new kernel
In fact the Open source driver seems to be better than the Windows driver for the desktop environment specifically....

Current issues:
GPU have locked itself in a higher clock state once.
Artifacts are seen when starting 3d applications semi to full-screen.
Artifacts was observed on all logo's in Deus Ex MD + in game, Jensen became a smurf.
short term artifacts on steam menu's when howering quickly between them..

but it's not any stable release I'm on but I'm a month into vega on Linux and I'm impressed!

Is there a debian specific way to use make-kpkg directly and build a true debian kernel based on this source?

Seriously? Are we that naive not to include a separate deb for the header files?

[Michael]

Still testing... Encountering many Vega hangs not sure yet if related to the kernel code or recent Mesa changes since my last Vega tests.

For the M-Bab kernel I recently had to revert to the 4.12 (with amd-staging-4.12 DC) kernel because several users reported stability issues with the 4.13 (based on amd-staging-drm-next) kernel: https://github.com/M-Bab/linux-kerne...commits/master

For the people missing the header package: It is included in my repo mentioned above.
