Spelling out _unlocked for each and every driver is a annoying. Especially if we consider how many drivers, do not know (or need to) about the horror stories involving struct_mutex. Just drop the suffix. It makes the API cleaner. Done via the following script: __from=drm_gem_object_put_unlocked __to=drm_gem_object_put for __file in $(git grep --name-only $__from); do sed -i "s/$__from/$__to/g" $__file; done Cc: Alex Deucher <alexander.deucher@amd.com> Cc: "Christian König" <christian.koenig@amd.com> Cc: "David (ChunMing) Zhou" <David1.Zhou@amd.com> Signed-off-by: NEmil Velikov <emil.velikov@collabora.com> Acked-by: NSam Ravnborg <sam@ravnborg.org> Acked-by: NThomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20200515095118.2743122-15-emil.l.velikov@gmail.com

This patch is a part of a series that extends kernel ABI to allow to pass tagged user pointers (with the top byte set to something else other than 0x00) as syscall arguments. In amdgpu_gem_userptr_ioctl() and amdgpu_amdkfd_gpuvm.c/init_user_pages() an MMU notifier is set up with a (tagged) userspace pointer. The untagged address should be used so that MMU notifiers for the untagged address get correctly matched up with the right BO. This patch untag user pointers in amdgpu_gem_userptr_ioctl() for the GEM case and in amdgpu_amdkfd_gpuvm_ alloc_memory_of_gpu() for the KFD case. This also makes sure that an untagged pointer is passed to amdgpu_ttm_tt_get_user_pages(), which uses it for vma lookups.

Use HMM helper function hmm_vma_fault() to get physical pages backing userptr and start CPU page table update track of those pages. Then use hmm_vma_range_done() to check if those pages are updated before amdgpu_cs_submit for gfx or before user queues are resumed for kfd. If userptr pages are updated, for gfx, amdgpu_cs_ioctl will restart from scratch, for kfd, restore worker is rescheduled to retry. HMM simplify the CPU page table concurrent update check, so remove guptasklock, mmu_invalidations, last_set_pages fields from amdgpu_ttm_tt struct.

The dumb_create API isn't intended for high performance rendering and it's more useful for userspace (ie. IGT) to have them precleared.
