AMD Makes More Updates Around New Radeon GPU Driver Code In Linux 6.2

RADEON --
Following last week's batch of AMDGPU/AMDKFD changes slated for Linux 6.2, on Friday another round of feature patches were sent in for DRM-Next ahead of the Linux 6.2 cycle. There is continued work around new IP blocks presumably for RDNA3 and MI300 graphics while given the more modularized development approach with block-by-block enablement makes it harder to ascertain the current status.

With this week's "new stuff" for the AMDGPU kernel driver in Linux 6.2 there are updates around the SMU 13.x, DCN 3.1.4, and DCN 3.2.x IP blocks among other fixes/improvements for newer hardware. We'll see next month on Phoronix when the Radeon RX 7900 series launches how well the open-source driver support is at-launch with whether Linux 6.0~6.1 is already "good enough" for Linux gamers or whether Linux 6.2 Git may be needed for good support. AMD has been working on the RDNA3 graphics card enablement for several kernel cycles now while more changes continue to land.

This week's set of AMDGPU updates also has a GPUVM TLB race fix, panel self refresh (PSR) fixes, a Vega 10 fan fix, a BACO (Bus Active, Chip Off) fix for Beige Goby, a GFXOFF fix, SR-IOV updates, and a variety of other fixes and enhancements.

The full list of feature patches from AMD this week for their kernel graphics driver in Linux 6.2 can be found via this pull request. The Linux 6.2 merge window is opening up following the v6.1 kernel release in early to mid December, though soon the DRM-Next cutoff will occur for new material aiming for this next kernel cycle.
