To allocate additional space for the dynamic cu masks. Confirmed with the hw team that we only need 1 dword for the mask. The mask is the same for each SE so you only need 1 dword. Reviewed-by:

Add 2 debugfs files, one that contains the VBIOS version, and one that contains the VBIOS itself. These won't change after initialization, so we can add the VBIOS version when we parse the atombios information. This ensures that we can find out the VBIOS version, even when the dmesg buffer fills up, and makes it easier to associate which VBIOS version is for which GPU on mGPU configurations. Set the size to 20 characters in case of some weird VBIOS version that exceeds the expected 17 character format (3-8-3\0). The VBIOS dump also allows for easy debugging v2: Move to debugfs, clarify commit message, add VBIOS dump file Signed-off-by: -

Also exports two functions that vendor drivers can call to trace DMA mappings. This is meant to help translate IOMMU mappings of bus addresses back to physical pages. Used by the umr amdgpu debugger for instance. Signed-off-by:

Check memory allocation failure and return -ENOMEM in such a case. 'num_post_dep_syncobjs' still has to be set to 0 before the test in order to have it initialized if 'amdgpu_cs_parser_fini()' is called to free resources. The calling graph would be, in such a case! failure in amdgpu_cs_process_syncobj_out_dep() ---> error code returned by amdgpu_cs_dependencies() --> amdgpu_cs_parser_fini() is called Reviewed-by:Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by:

KIQ doesn't really use the GPU scheduler. The base drivers generally use the KIQ ring directly rather than submitting IBs. However, amdgpu_sched_hw_submission (which defaults to 2) limits the number of outstanding fences to 2. KFD uses the KIQ for TLB flushes and the 2 fence limit hurts performance when there are several KFD processes running. v2: move some expressions to one line change KIQ sched_hw_submission to at least 16 v3: bump to 256 Reviewed-by: -

Set the shadow flag on the shadow and not the parent, always bind shadow BOs during allocation instead of manually, use the reservation_object wrappers to grab the lock. This fixes a couple of issues with binding the shadow BOs as well as correctly evicting them when memory becomes tight. Signed-off-by:
