AMD Readies More Graphics Driver Improvements For Linux 6.15

Last week AMD sent out a big batch of new graphics driver code for Linux 6.15 including new GPU support, OEM i2c support for RGB lighting and other features, and other updates. Another round of AMDGPU/AMDKFD feature code targeting the upcoming Linux 6.15 merge window was sent out on Friday.

Ahead of the Linux 6.15 merge window opening up in late March, yesterday another round of AMDGPU/AMDKFD updates were sent out for DRM-Next.

This week’s batch of AMD kernel graphics driver code includes more work on the IP/per-block enumeration of AMD GPUs, suspend and resume fixes for aging GCN 1.0/1.1 hardware, SDMA engine reset support on SDMA 4.4.2 IP, JPEG 5.0.1 engine reset support, Panel Self Refresh (PSR) fixes, Embedded DisplayPort (eDP) fixes, AMDKFD compute driver can now handle cooperative launch on GFX12/RDNA4 GPUs, and other updates.

The highlights include:

amdgpu:
– Prevent KFD from being evicted when a exported BO is released
– Finish ip block transition for IP blocks
– Suspend and resume dpm fixes for SI/CIK
– Initial SDMA engine reset support for SDMA 4.4.2
– Documentation updates
– JPEG fixes
– SMU 13.0.12 updates
– Fix for runtime PM on DELL G5 SE
– MAINTAINERS updates
