SR-IOV need to reserve a piece of shared VRAM at the exact place to exchange data betweem PF and VF. The start address and size of the shared mem are passed to guest through VBIOS structure VRAM_UsageByFirmware. VRAM_UsageByFirmware is a general feature in VBIOS, it indicates that VBIOS need to reserve a piece of memory on the VRAM. Because the mem address is specified. Reserve it early in amdgpu_ttm_init to make sure that it can monoplize the space. Signed-off-by:

Nicolai Hähnle authored
Highly concurrent Piglit runs can trigger a race condition where a pending SDMA job on a buffer object is never executed because the corresponding process is killed (perhaps due to a crash). Since the job's fences were never signaled, the buffer object was effectively leaked. Worse, the buffer was stuck wherever it happened to be at the time, possibly in VRAM. The symptom was user space processes stuck in interruptible waits with kernel stacks like: [<ffffffffbc5e6722>] dma_fence_default_wait+0x112/0x250 [<ffffffffbc5e6399>] dma_fence_wait_timeout+0x39/0xf0 [<ffffffffbc5e82d2>] reservation_object_wait_timeout_rcu+0x1c2/0x300 [<ffffffffc03ce56f>] ttm_bo_cleanup_refs_and_unlock+0xff/0x1a0 [ttm] [<ffffffffc03cf1ea>] ttm_mem_evict_first+0xba/0x1a0 [ttm] [<ffffffffc03cf611>] ttm_bo_mem_space+0x341/0x4c0 [ttm] [<ffffffffc03cfc54>] ttm_bo_validate+0xd4/0x150 [ttm] [<ffffffffc03cffbd>] ttm_bo_init_reserved+0x2ed/0x420 [ttm] [<ffffffffc042f523>] amdgpu_bo_create_restricted+0x1f3/0x470 [amdgpu] [<ffffffffc042f9fa>] amdgpu_bo_create+0xda/0x220 [amdgpu] [<ffffffffc04349ea>] amdgpu_gem_object_create+0xaa/0x140 [amdgpu] [<ffffffffc0434f97>] amdgpu_gem_create_ioctl+0x97/0x120 [amdgpu] [<ffffffffc037ddba>] drm_ioctl+0x1fa/0x480 [drm] [<ffffffffc041904f>] amdgpu_drm_ioctl+0x4f/0x90 [amdgpu] [<ffffffffbc23db33>] do_vfs_ioctl+0xa3/0x5f0 [<ffffffffbc23e0f9>] SyS_ioctl+0x79/0x90 [<ffffffffbc864ffb>] entry_SYSCALL_64_fastpath+0x1e/0xad [<ffffffffffffffff>] 0xffffffffffffffff Note: The correctness of this change depends on the earlier commit "drm/amd/sched: move adding finish callback to amd_sched_job_begin" v2: set an error on the finished fence Signed-off-by:Nicolai Hähnle <nicolai.haehnle@amd.com> Reviewed-by:
