2019-11-26drm/amdgpu: Optimize KFD page table reservationFelix Kuehling
Be less pessimistic about estimated page table use for KFD. Most allocations use 2MB pages and therefore need less VRAM for page tables. This allows more VRAM to be used for applications especially on large systems with many GPUs and hundreds of GB of system memory. Example: 8 GPUs with 32GB VRAM each + 256GB system memory = 512GB Old page table reservation per GPU: 1GB New page table reservation per GPU: 32MB Signed-off-by: Felix Kuehling <Felix.Kuehling@amd.com> Reviewed-by: xinhui pan <xinhui.pan@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

It may lose gpuvm invalidate acknowldege state across power-gating off cycle. To avoid this issue in gmc9/gmc10 invalidation, add semaphore acquire before invalidation and semaphore release after invalidation. After adding semaphore acquire before invalidation, the semaphore register become read-only if another process try to acquire semaphore. Then it will not be able to release this semaphore. Then it may cause deadlock problem. If this deadlock problem happens, it needs a semaphore firmware fix.
