drm/amdgpu: Create version number for coredumps

2023-10-20T19:11:29Z

Even if there's nothing currently parsing amdgpu's coredump files, if we eventually have such tools they will be glad to find a version field to properly read the file. Create a version number to be displayed on top of coredump file, to be incremented when the file format or content get changed.

drm/amdgpu: Keep reset handlers shared

2023-08-30T18:57:54Z

Instead of maintaining a list per device, keep the reset handlers common per ASIC family. A pointer to the list of handlers is maintained in reset control. Signed-off-by: Lijo Lazar Reviewed-by: Le Ma Reviewed-by: Asad Kamal Tested-by: Asad Kamal Signed-off-by: Alex Deucher

drm/amdgpu: Fix ENOSYS means 'invalid syscall nr' in amdgpu_device.c

ENOSYS should be used for nonexistent syscalls only, replace ENOSYS with EOPNOTSUPP for reset handlers that are not implemented for respective ASIC.
