drm/amdgpu: user pages array memory leak fix

2019-10-17T21:12:34Z

user_pages array should always be freed after validation regardless if user pages are changed after bo is created because with HMM change parse bo always allocate user pages array to get user pages for userptr bo. v2: remove unused local variable and amend commit v3: add back get user pages in gem_userptr_ioctl, to detect application bug where an userptr VMA is not ananymous memory and reject it.

drm/amdgpu: prevent memory leaks in AMDGPU_CS ioctl

2019-08-22T03:18:38Z

Error out if the AMDGPU_CS ioctl is called with multiple SYNCOBJ_OUT and/or TIMELINE_SIGNAL chunks, since otherwise the last chunk wins while the allocated array as well as the reference counts of sync objects are leaked.

drm/amdgpu: Prepare for hmm_range_register API change (v2)

2019-07-08T18:55:00Z

An upcoming change in the hmm_range_register API requires passing in a pointer to an hmm_mirror instead of mm_struct. To access the hmm_mirror we need pass bo instead of ttm to amdgpu_ttm_tt_get_user_pages because mirror is part of amdgpu_mn structure, which is accessible from bo. v2: fix building without CONFIG_HMM_MIRROR (Arnd) Signed-off-by: Philip Yang Signed-off-by: Felix Kuehling Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher
