2019-08-02drm/amdgpu: Mark KFD VRAM allocations for wipe on releaseFelix Kuehling
Memory used by KFD applications can contain sensitive information that should not be leaked to other processes. The current approach to prevent leaks is to clear VRAM at allocation time. This is not effective because memory can be reused in other ways without being cleared. Synchronously clearing memory on the allocation path also carries a significant performance penalty. Stop clearing memory at allocation time. Instead mark the memory for wipe on release.

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 <Philip.Yang@amd.com> Signed-off-by: Felix Kuehling <Felix.Kuehling@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
