drm/amdgpu: implement TMZ accessor (v3)

2020-04-28T20:20:29Z

Implement an accessor of adev->tmz.enabled. Let not code around access it as "if (adev->tmz.enabled)" as the organization may change. Instead... Recruit "bool amdgpu_is_tmz(adev)" to return exactly this Boolean value. That is, this function is now an accessor of an already initialized and set adev and adev->tmz. Add "void amdgpu_gmc_tmz_set(adev)" to check and set adev->gmc.tmz_enabled at initialization time. After which one uses "bool amdgpu_is_tmz(adev)" to query whether adev supports TMZ. Also, remove circular header file include. v2: Remove amdgpu_tmz.[ch] as requested. v3: Move TMZ into GMC. Signed-off-by: Luben Tuikov Acked-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: fix modprobe failure of the secondary GPU when GDDR6 training enabled(V5)

2020-01-16T18:35:37Z

[why] In dual GPUs scenario, stolen_size is assigned to zero on the secondary GPU, since there is no pre-OS console using that memory. Then the bottom region of VRAM was allocated as GTT, unfortunately a small region of bottom VRAM was encroached by UMC firmware during GDDR6 BIST training, this cause page fault. [how] Forcing stolen_size to 3MB, then the bottom region of VRAM was allocated as stolen memory, GTT corruption avoid.

drm/amdgpu: initialize vm_inv_eng0_sem for gfxhub and mmhub

2019-11-22T19:55:19Z

SW must acquire/release one of the vm_invalidate_eng*_sem around the invalidation req/ack. Through this way,it can avoid losing invalidate acknowledge state across power-gating off cycle. To use vm_invalidate_eng*_sem, it needs to initialize vm_invalidate_eng*_sem firstly. Signed-off-by: changzhu Reviewed-by: Christian König Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org
