From 4ff37a83f19dab4e67299325ee22e98346eee857 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Christian=20K=C3=B6nig?= Date: Fri, 26 Feb 2016 16:18:26 +0100 Subject: drm/amdgpu: fix VM faults caused by vm_grab_id() v4 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The owner must be per ring as long as we don't support sharing VMIDs per process. Also move the assigned VMID and page directory address into the IB structure. v3: assign the VMID to all IBs, not just the first one. v4: use correct pointer for owner Signed-off-by: Christian König Reviewed-by: Chunming Zhou Acked-by: Alex Deucher Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/sdma_v2_4.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/gpu/drm/amd/amdgpu/sdma_v2_4.c') diff --git a/drivers/gpu/drm/amd/amdgpu/sdma_v2_4.c b/drivers/gpu/drm/amd/amdgpu/sdma_v2_4.c index 29ec986..dddb8d6 100644 --- a/drivers/gpu/drm/amd/amdgpu/sdma_v2_4.c +++ b/drivers/gpu/drm/amd/amdgpu/sdma_v2_4.c @@ -244,7 +244,7 @@ static void sdma_v2_4_ring_insert_nop(struct amdgpu_ring *ring, uint32_t count) static void sdma_v2_4_ring_emit_ib(struct amdgpu_ring *ring, struct amdgpu_ib *ib) { - u32 vmid = (ib->vm ? ib->vm->ids[ring->idx].id : 0) & 0xf; + u32 vmid = ib->vm_id & 0xf; u32 next_rptr = ring->wptr + 5; while ((next_rptr & 7) != 2) -- cgit v1.1
