Important AMDGPU & AMDKFD Driver Improvements Readied For Linux 6.20~7.0
On Friday AMD sent out another set of AMDGPU kernel graphics driver and AMDKFD kernel compute driver patches for queuing in DRM-Next ahead of the upcoming Linux 6.20~7.0 kernel cycle kicking off in February.
Already queued in DRM-Next ahead of this next Linux kernel merge window is enabling new graphics IP for upcoming products, including an additional RDNA 3.5 target and preparing for the little-detailed GFX12.1 RDNA4-based hardware.
With this week's pull request, there are more updates to the SMU 15 system management code introduced in the prior code. Plus various SMU 14.x IP fixes too. There are also SR-IOV fixes, user queue "UserQ" fixes, reworking the SMU mailbox handling, MES micro-engine scheduler fixes, and other fixes to the AMDGPU driver.
One patch that is included in this week's pull worth highlighting once again is the AMD display patch to bump the HDMI clock to 340MHz where possible. That patch is for improving DP-HDMI dongles with the AMDGPU driver. The display code was previously limited to 165MHz and never updated to the HDMI 1.3 capable 340MHz spec. With this patch now going into the next kernel version, for those using DP-HDMI dongles it will help some configurations for driving higher resolution and/or higher refresh rates.
On the AMDKFD compute driver side, there is a memory leak fix and other fixes. Also standing out there are some fixes for systems with non-4K kernel page sizes. In particular, that should help out some ARM64 servers and the like with 64K page sizes while using Instinct or Radeon hardware.
The full list of AMDGPU/AMDKFD patches for the week heading toward Linux 6.20~7.0 can be found via this pull request.
