drm/amdkfd: Store xcp partition id to amdgpu bo

2023-06-09T14:36:38+00:00

For memory accounting per compute partition and export drm amdgpu bo and then import to KFD, we need the xcp id to account the memory usage or find the KFD node of the original amdgpu bo to create the KFD bo on the correct adev KFD node. Set xcp_id_plus1 of amdgpu_bo_param to create bo and store xcp_id to amddgpu bo. Add helper macro to get the mem_id from adev and xcp_id. v2: squash in fix ("drm/amdgpu: Fix BO creation failure on GFX 9.4.3 dGPU") Signed-off-by: Philip Yang Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Add memory partition mem_id to amdgpu_bo

2023-06-09T14:00:00+00:00

Add mem_id_plus1 parameter to amdgpu_gem_object_create and pass it to amdgpu_bo_create. For dGPU mode allocation, mem_id is used by VRAM manager to get the memory partition fpfn, lpfn from xcp manager. For APU native mode allocation, mem_id is used to get NUMA node id from xcp manager, then pass to TTM as numa pool id to alloc memory from the specific NUMA node. mem_id -1 means for entire VRAM or any NUMA nodes.

drm/amdgpu: Introduce GEM object functions

2020-09-25T07:19:42+00:00

GEM object functions deprecate several similar callback interfaces in struct drm_driver. This patch replaces the per-driver callbacks with per-instance callbacks in amdgpu. The only exception is gem_prime_mmap, which is non-trivial to convert. v3: * remove amdgpu_object.c from patch (Christian) v2: * move object-function instance to amdgpu_gem.c (Christian) * set callbacks in amdgpu_gem_object_create() (Christian) Signed-off-by: Thomas Zimmermann Reviewed-by: Christian König Link: https://patchwork.freedesktop.org/patch/msgid/20200923102159.24084-2-tzimmermann@suse.de

drm/amdgpu: cleanup mtype mapping

2019-09-16T14:59:21+00:00

Unify how we map the UAPI flags to the PTE hardware flags for a mapping. Only the MTYPE is actually ASIC dependent, all other flags should be copied over 1 to 1 and ASIC differences are handled later on. Signed-off-by: Christian König Signed-off-by: Alex Deucher

We are getting a dma-buf implementation completely separate from drm prime, so rename the files now and cleanup the code a bit. No functional change. Signed-off-by: Christian König Acked-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdkfd: Add DMABuf import functionality

2018-12-07T23:13:54+00:00

This is used for interoperability between ROCm compute and graphics APIs. It allows importing graphics driver BOs into the ROCm SVM address space for zero-copy GPU access. The API is split into two steps (query and import) to allow user mode to manage the virtual address space allocation for the imported buffer.
