2018-08-16drm/amdgpu: Use kvmalloc for allocating UVD/VCE/VCN BO backup memoryMichel Dänzer
The allocated size can be (at least?) as large as megabytes, and there's no need for it to be physically contiguous. May avoid spurious failures to initialize / suspend the corresponding block while there's memory pressure.

2018-08-13drm/amd/display: Guard against null crtc in CRC IRQNicholas Kazlauskas
[Why] A null pointer deference can occur if crtc is null in amdgpu_dm_crtc_handle_crc_irq. This can happen if get_crtc_by_otg_inst returns NULL during dm_crtc_high_irq, leading to a hang in some IGT test cases. [How] Check that CRTC is non-null before accessing its fields.

Extend the timeout for recovering vram bos from shadows on sr-iov to cover the worst case scenario for timeslices and VFs Under runtime, the wait fence time could be quite long when other VFs are in exclusive mode. For example, for 4 VF, every VF's exclusive timeout time is set to 3s, then the worst case is 9s. If the VF number is more than 4,then the worst case time will be longer. The 8s is the test data, with setting to 8s, it will pass the TDR test for 1000 times.

2018-08-06drm/scheduler: fix timeout worker setup for out of order job completionsLucas Stach
drm_sched_job_finish() is a work item scheduled for each finished job on a unbound system workqueue. This means the workers can execute out of order with regard to the real hardware job completions. If this happens queueing a timeout worker for the first job on the ring mirror list is wrong, as this may be a job which has already finished executing. Fix this by reorganizing the code to always queue the worker for the next job on the list, if this job hasn't finished yet. This is robust against a potential reordering of the finish workers. Also move out the timeout worker cancelling, so that we don't need to take the job list lock twice. As a small optimization list_del is used to remove the job from the ring mirror list, as there is no need to reinit the list head in the job we are about to free.

gvt_pin_guest_page extracted some of the gvt_dma_map_page functionality: commit 79e542f5af79 ("drm/i915/kvmgt: Support setting dma map for huge pages") And yet, part of it was reintroduced in: commit 39b4cbadb9a9 ("drm/i915/kvmgt: Check the pfn got from vfio_pin_pages") Causing kvmgt part to no longer build. Let's remove it.

2018-08-06drm/i915/lpe: Mark LPE audio runtime pm as "no callbacks"Chris Wilson
The LPE audio is a child device of i915, it is powered up and down alongside the igfx and presents no independent runtime interface. This aptly fulfils the description of a "No-Callback" Device, so mark it thus.

2018-08-06Revert "drm/i915/icl: WaEnableFloatBlendOptimization"Mika Kuoppala
The register for 0xe420 is unable to hold any value, including this bit. The documentation is also mixed between having a register bit for toggle and having a state command setup for it. Apparently the register toggle is deprecated. Remove the register toggle as evidence shows it's futile. The thing remaining is an apology and humble request for Mesa folks to resurrect their state setup for this as they were on right track from start. This reverts commit 0bf059f3532bb39c52d917142206a8554fc2f1c5.
