drm/amdgpu: Implement a new 64bit sequence memory driver

2023-11-17T14:29:53Z

Developed a new driver which allocates a 64bit memory on each request in sequence order. At the moment, user queue fence memory is the main consumer of this seq64 driver. v2: Worked on review comments from Christian for the following modifications - Move driver name from "semaphore" to "seq64" - Remove unnecessary PT/PD mapping - Move enable_mes check into init/fini functions. v3: Worked on review comments from Christian - drop enable_mes check - use DECLARE_BITMAP for bit array - added kerneldoc for seq64 v4: Worked on review comments from Christian - Rename amdgpu_seq64_get name with amdgpu_seq64_alloc v5: Worked on review comments from Christian - Fix seq64 lockdep warning - move fpriv->seq64_va check into amdgpu_seq64_unmap() - make the function amdgpu_seq64_unmap() return as void. - reserve the buffers as not interruptible. v6: port to drm_exec (Alex) v7: disable for now (Arun) Signed-off-by: Arunpravin Paneer Selvam Reviewed-by: Christian König Signed-off-by: Alex Deucher
