drm/amdkfd: drop IOMMUv2 support

2023-08-11T18:47:25Z

Now that we use the dGPU path for all APUs, drop the IOMMUv2 support. v2: drop the now unused queue manager functions for gfx7/8 APUs Reviewed-by: Felix Kuehling Acked-by: Christian König Tested-by: Mike Lothian Signed-off-by: Alex Deucher

drm/amdkfd: Define config HSA_AMD_P2P to support peer-to-peer

2022-06-08T15:40:12Z

Extend current kernel config requirements of amdgpu by adding config HSA_AMD_P2P. Enabling HSA_AMD_P2P is REQUIRED to support peer-to-peer communication between AMD GPU devices over PCIe bus Signed-off-by: Ramesh Errabolu Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Add CONFIG_HSA_AMD_SVM

2021-04-21T01:50:35Z

Control whether to build SVM support into amdgpu with a Kconfig option. This makes it easier to disable it in production kernels if this new feature causes problems in production environments. Use "depends on" instead of "select" for DEVICE_PRIVATE, as is recommended for visible options. Reviewed-by: Philip Yang Signed-off-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: register HMM device private zone

2021-04-21T01:47:54Z

Register vram memory as MEMORY_DEVICE_PRIVATE type resource, to allocate vram backing pages for page migration. Signed-off-by: Philip Yang Reviewed-by: Felix Kuehling Signed-off-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Enable userptr support when KFD is enabled

2021-01-21T14:55:16Z

ROCm user mode depends on userptr support. Without it, KFD is basically useless. Make sure HSA_AMD selects the same options as DRM_AMDGPU_USERPTR to avoid broken configurations where userptr gets enabled but its dependencies are disabled.
