AMD continues preparing more kernel driver code for Linux 6.19. This week another round of AMDGPU kernel graphics driver updates were submitted to DRM-Next ahead of the early December merge window.
In addition to prior AMDGPU updates intended for Linux 6.19 like more GCN 1.0 era hardware work for the AMDGPU driver driven by Valve, this week’s round of AMDGPU and AMDKFD updates is mostly around bug fixes and other low-level work.
Enhancing the user mode queues “UserQ” support remains a frequent area of kernel driver work this year. AMDGPU UserQ work in this pull request includes hardware reset support. Plus there are clean-ups for the Heterogeneous Memory Management (HMM) code, updates to various IP blocks, continued suspend/resume enhancements, seemingly never-ending DisplayPort Multi-Stream Transport (DP MST) fixes, and other general fixes.
