drm/amdkfd: Add metadata ring buffer for compute

2026-01-05T21:59:56+00:00

Add support for separate ring-buffer for metadata packets when using compute queues. Userspace application allocate the metadata ring-buffer and the queue ring-buffer with a single allocation.

amdkfd: Bump ABI to indicate presence of Trap handler support for expert scheduling

2025-12-08T19:23:21+00:00

commit 0f0c8a6983db ("drm/amdkfd: Trap handler support for expert scheduling mode") introduced support for a trap handler when expert scheduling mode. However userspace needs to know whether or not a trap handler support is present. Bump the KFD IOCTL API so that userspace can key off this to decide.

amdkfd: introduce new ioctl AMDKFD_IOC_CREATE_PROCESS

2025-12-08T19:19:34+00:00

This commit implemetns a new ioctl AMDKFD_IOC_CREATE_PROCESS that creates a new secondary kfd_progress on the FD. To keep backward compatibility, userspace programs need to invoke this ioctl explicitly on a FD to create a secondary kfd_process which replacing its primary kfd_process. This commit bumps ioctl minor version. Signed-off-by: Zhu Lingshan Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher
