2023-06-09drm/amdgpu: Move initialization of xcp before kfdLijo Lazar
After partition switch, fill all relevant xcp information before kfd starts initialization. Signed-off-by: Lijo Lazar <lijo.lazar@amd.com> Reviewed-by: Le Ma <le.ma@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2023-06-09drm/amdgpu: Add callback to fill xcp memory idLijo Lazar
Add callback in xcp interface to fill xcp memory id information. Memory id is used to identify the range/partition of an XCP from the available memory partitions in device. Also, fill the id information. Signed-off-by: Lijo Lazar <lijo.lazar@amd.com> Reviewed-by: Le Ma <le.ma@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2023-06-09drm/amdgpu: Use transient mode during xcp switchLijo Lazar
During partition switch, keep the state as transient mode. Fetch the latest state if switch fails. Signed-off-by: Lijo Lazar <lijo.lazar@amd.com> Reviewed-by: Hawking Zhang <Hawking.Zhang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2023-06-09drm/amdgpu: Add flags for partition mode queryLijo Lazar
It's not required to take lock on all cases while querying partition mode. Querying partition mode during KFD init process doesn't need to take a lock. Init process after a switch will already be happening under lock. Control the behaviour by adding flags to xcp_query_partition_mode.

2023-06-09drm/amdgpu: Add initial version of XCP routinesLijo Lazar
Within a device, an accelerator core partition can be constituted with different IP instances. These partitions are spatial in nature. Number of partitions which can exist at the same time depends on the 'partition mode'. Add a manager entity which is responsible for switching between different partition modes and maintaining partitions. It is also responsible for suspend/resume of different partitions.
