drm/amdkfd: Fix UBSAN shift-out-of-bounds warning

2022-10-24T07:58:20Z

[ Upstream commit b292cafe2dd02d96a07147e4b160927e8399d5cc ] This was fixed in initialize_cpsch before, but not in initialize_nocpsch. Factor sdma bitmap initialization into a helper function to apply the correct implementation in both cases without duplicating it. v2: Added a range check Reported-by: Ellis Michael Signed-off-by: Felix Kuehling Reviewed-by: Graham Sider Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

drm/amdkfd: Handle restart of kfd_ioctl_wait_events

2022-09-05T08:31:32Z

[ Upstream commit bea9a56afbc4b5a41ea579b8b0dc5e189b439504 ] When kfd_ioctl_wait_events needs to restart due to a signal, we need to update the timeout to account for the time already elapsed. We also need to undo auto_reset of events that have signaled already, so that the restarted ioctl will be able to count those signals again. This fixes infinite hangs when kfd_ioctl_wait_events is interrupted by a signal.

drm/amdkfd: Fix partial migration bugs

2022-06-03T20:43:22Z

Migration range from system memory to VRAM, if system page can not be locked or unmapped, we do partial migration and leave some pages in system memory. Several bugs found to copy pages and update GPU mapping for this situation: 1. copy to vram should use migrate->npage which is total pages of range as npages, not migrate->cpages which is number of pages can be migrated. 2. After partial copy, set VRAM res cursor as j + 1, j is number of system pages copied plus 1 page to skip copy. 3. copy to ram, should collect all continuous VRAM pages and copy together. 4. Call amdgpu_vm_update_range, should pass in offset as bytes, not as number of pages. Signed-off-by: Philip Yang Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org
