AMDGPU Changes Readied For Linux 6.13: Runtime Repartitioning, Many Fixes

A big batch of AMDGPU/AMDKFD kernel graphics and compute driver updates were mailed in for DRM-Next ahead of the upcoming Linux 6.13 kernel cycle.

A bunch of "new stuff" was submitted by AMD for their Radeon and Instinct updates destined for the Linux 6.13 kernel. Among the changes are adding SDMA queue reset support in the event of problems, initial runtime repartitioning support with a focus on compute workloads, brightness control updates, better handling multiple instances of an IP block, and a lot of fixes/updates pertaining to recent and upcoming hardware support.

This morning's AMDGPU pull request sums up this batch of Linux 6.13 changes as:

amdgpu:
- SDMA queue reset support
- SMU 13.0.6 updates
- Add debugfs interface to help limit jpeg queue scheduling for testing
- JPEG 4.0.3 updates
- Initial runtime repartitioning support
- GFX9 fixes
- Misc code cleanups
- Rework IP structures to better handle multiple instances of an IP
- DML updates
- DSC fixes
- HDR fixes
- Brightness control updates
- Runtime pm cleanup
- DMCUB fixes
- DCN 3.5 updates
- Struct drm_edid cleanup
- Fetch EDID from _DDC if available
- Ring noop optimizations

- 3DLUT fixes
- DCN 4.x fixes
- SMU 13.x fixes
- Fixes for set_soft_freq_range()
- ACPI fixes
- SMU 14.x updates
