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

2016-11-26T08:54:52+00:00

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: fix DP mode validation

2016-11-15T06:46:40+00:00

commit c47b9e0944e483309d66c807d650ac8b8ceafb57 upstream. Switch the order of the loops to walk the rates on the top so we exhaust all DP 1.1 rate/lane combinations before trying DP 1.2 rate/lane combos. This avoids selecting rates that are supported by the monitor, but not the connector leading to valid modes getting rejected. bug: https://bugs.freedesktop.org/show_bug.cgi?id=95206 Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman
