2025-05-16drm/amdgpu: Use compatible NPS mode infoLijo Lazar
Compatible NPS modes for a partition mode are exposed through xcp_config interface. To determine if a compute partition mode is valid, check if the current NPS mode is part of compatible NPS modes.

2024-08-20drm/amdgpu/gfx_v9_4_3: Apply Isolation Enforcement to GFX & Compute ringsSrinivasan Shanmugam
This commit applies isolation enforcement to the GFX and Compute rings in the gfx_v9_4_3 module. The commit sets `amdgpu_gfx_enforce_isolation_ring_begin_use` and `amdgpu_gfx_enforce_isolation_ring_end_use` as the functions to be called when a ring begins and ends its use, respectively. `amdgpu_gfx_enforce_isolation_ring_begin_use` is called when a ring begins its use. This function cancels any scheduled `enforce_isolation_work` and, if necessary, signals the Kernel Fusion Driver (KFD) to stop the runqueue. `amdgpu_gfx_enforce_isolation_ring_end_use` is called when a ring ends its use. This function schedules `enforce_isolation_work` to be run after a delay. These functions are part of the Enforce Isolation Handler, which enforces shader isolation on AMD GPUs to prevent data leakage between different processes. The commit also includes a check for the type of the ring. If the type of the ring is `AMDGPU_RING_TYPE_COMPUTE`, the `xcp_id` of the `enforce_isolation` structure in the `gfx` structure of the `amdgpu_device` is set to the `xcp_id` of the ring. This ensures that the correct `xcp_id` is used when enforcing isolation on compute rings. The `xcp_id` is an identifier for an XCP partition, and different rings can be associated with different XCP partitions.
