2023-09-26drm/amdgpu: Restore partition mode after resetLijo Lazar1-0/+1
On a full device reset, PSP FW gets unloaded. Hence restore the partition mode by placing a new request.

2023-07-18drm/amdgpu: use a macro to define no xcp partition caseGuchun Chen1-0/+2
~0 as no xcp partition is used in several places, so improve its definition by a macro for code consistency.

2023-06-09drm/amdkfd: Fix memory reporting on GFX 9.4.3Mukul Joshi1-0/+5
This patch fixes memory reporting on the GFX 9.4.3 APU and dGPU by reporting available memory on a per partition basis. If its an APU, available and used memory calculations take into account system and TTM memory. v2: squash in fix ("drm/amdkfd: Fix array out of bound warning") squash in fix ("drm/amdgpu: Update memory reporting for GFX9.4.3") Signed-off-by: Mukul Joshi <mukul.joshi@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2023-06-09drm/amdgpu: Add flags for partition mode queryLijo Lazar1-1/+4
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 Lazar1-0/+107
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.
