drm/amdgpu: Attach exclusive fence to prime exported bo's. (v5)

2016-11-26T08:54:52Z

commit 8e94a46c1770884166b31adc99eba7da65a446a7 upstream. External clients which import our bo's wait only for exclusive dmabuf-fences, not on shared ones, ditto for bo's which we import from external providers and write to. Therefore attach exclusive fences on prime shared buffers if our exported buffer gets imported by an external client, or if we import a buffer from an external exporter. See discussion in thread: https://lists.freedesktop.org/archives/dri-devel/2016-October/122370.html Prime export tested on Intel iGPU + AMD Tonga dGPU as DRI3/Present Prime render offload, and with the Tonga standalone as primary gpu. v2: Add a wait for all shared fences before prime export, as suggested by Christian Koenig. v3: - Mark buffer prime_exported in amdgpu_gem_prime_pin, so we only use the exclusive fence when exporting a bo to external clients like a separate iGPU, but not when exporting/importing from/to ourselves as part of regular DRI3 fd passing. - Propagate failure of reservation_object_wait_rcu back to caller. v4: - Switch to a prime_shared_count counter instead of a flag, which gets in/decremented on prime_pin/unpin, so we can switch back to shared fences if all clients detach from our exported bo. - Also switch to exclusive fence for prime imported bo's. v5: - Drop lret, instead use int ret -> long ret, as proposed by Christian.

drm/amdgpu: Change GART offset to 64-bit

2016-09-07T06:32:42Z

commit cab0b8d50e9bbef62c04067072c953433a87a9ff upstream. The GART aperture size can be bigger than 4GB. Therefore the offset used in amdgpu_gart_bind and amdgpu_gart_unbind must be 64-bit.

drm/amdgpu: fix issue with overlapping userptrs

commit cc1de6e800c253172334f8774c419dc64401cd2e upstream. Otherwise we could try to evict overlapping userptr BOs in get_user_pages(), leading to a possible circular locking dependency. Signed-off-by: Christian König Acked-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/amdgpu: fix user fence handling

2015-12-16T22:48:59Z

This fixes a random corruption under memory pressure. We need to fence the BO for the user fence as well, otherwise it might be swapped out and the GPU could write the fence value to an undesired location.
