drm/amdgpu: wait for moving fence after pinning

2021-06-22T13:29:03Z

We actually need to wait for the moving fence after pinning the BO to make sure that the pin is completed.

drm/amdgpu: remove amdgpu_vm_pt

drm/ttm: rename bo->mem and make it a pointer

2021-06-02T09:07:25Z

When we want to decouble resource management from buffer management we need to be able to handle resources separately. Add a resource pointer and rename bo->mem so that all code needs to change to access the pointer instead. No functional change.

drm/amdgpu: Implement mmap as GEM object function

2021-05-26T18:56:23Z

Moving the driver-specific mmap code into a GEM object function allows for using DRM helpers for various mmap callbacks. This change resolves several inconsistencies between regular mmap and prime-based mmap. The vm_ops field in vma is now set for all mmap'ed areas. Previously it way only set for regular mmap calls, prime-based mmap used TTM's default vm_ops. The function amdgpu_verify_access() is no longer being called and therefore removed by this patch. As a side effect, amdgpu_ttm_vm_ops and amdgpu_ttm_fault() are now implemented in amdgpu's GEM code. v4: * rebased v3: * rename mmap function to amdgpu_gem_object_mmap() (Christian) * remove unnecessary checks from mmap (Christian) v2: * rename amdgpu_ttm_vm_ops and amdgpu_ttm_fault() to amdgpu_gem_vm_ops and amdgpu_gem_fault() (Christian) * the check for kfd_bo has meanwhile been removed Signed-off-by: Thomas Zimmermann Reviewed-by: Christian König Link: https://patchwork.freedesktop.org/patch/msgid/20210525151055.8174-3-tzimmermann@suse.de

drm/amdgpu: Use iterator methods exposed by amdgpu_res_cursor.h in building SG_TABLE's for a VRAM BO

2021-04-15T20:32:44Z

Extend current implementation of SG_TABLE construction method to allow exportation of sub-buffers of a VRAM BO. This capability will enable logical partitioning of a VRAM BO into multiple non-overlapping sub-buffers. One example of this use case is to partition a VRAM BO into two sub-buffers, one for SRC and another for DST. Reviewed-by: Christian König Signed-off-by: Ramesh Errabolu Signed-off-by: Alex Deucher

drm/amdgpu: Set GTT_USWC flag to enable freesync v2

2021-03-24T03:01:42Z

This patch sets 'AMDGPU_GEM_CREATE_CPU_GTT_USWC' as input parameter flag, during object creation of an imported DMA buffer. In absence of this flag: 1. Function amdgpu_display_supported_domains() doesn't add AMDGPU_GEM_DOMAIN_GTT as supported domain. 2. Due to which, Function amdgpu_display_user_framebuffer_create() refuses to create framebuffer for imported DMA buffers. 3. Due to which, AddFB() IOCTL fails. 4. Due to which, amdgpu_present_check_flip() check fails in DDX 5. Due to which DDX driver doesn't allow flips (goes to blitting) 6. Due to which setting Freesync/VRR property fails for PRIME buffers. So, this patch finally enables Freesync with PRIME buffer offloading. v2 (chk): instead of just checking the flag we copy it over if the exporter is an amdgpu device as well.
