Pull drm updates from Dave Airlie: "This seems to have been a comparatively quieter merge window, I assume due to holidays etc. The "biggest" change is AMD header cleanups, which merge/remove a bunch of them. The AMD gpu scheduler is now being made generic with the etnaviv driver wanting to reuse the code, hopefully other drivers can go in the same direction. Otherwise it's the usual lots of stuff in i915/amdgpu, not so much stuff elsewhere. Core: - Add .last_close and .output_poll_changed helpers to reduce driver footprints - Fix plane clipping - Improved debug printing support - Add panel orientation property - Update edid derived properties at edid setting - Reduction in fbdev driver footprint - Move amdgpu scheduler into core for other drivers to use. i915: - Selftest and IGT improvements - Fast boot prep work on IPS, pipe config - HW workarounds for Cannonlake, Geminilake - Cannonlake clock and HDMI2.0 fixes - GPU cache invalidation and context switch improvements - Display planes cleanup - New PMU interface for perf queries - New firmware support for KBL/SKL - Geminilake HW workaround for perforamce - Coffeelake stolen memory improvements - GPU reset robustness work - Cannonlake horizontal plane flipping - GVT work amdgpu/radeon: - RV and Vega header file cleanups (lots of lines gone!) - TTM operation context support - 48-bit GPUVM support for Vega/RV - ECC support for Vega - Resizeable BAR support - Multi-display sync support - Enable swapout for reserved BOs during allocation - S3 fixes on Raven - GPU reset cleanup and fixes - 2+1 level GPU page table amdkfd: - GFX7/8 SDMA user queues support - Hardware scheduling for multiple processes - dGPU prep work rcar: - Added R8A7743/5 support - System suspend/resume support sun4i: - Multi-plane support for YUV formats - A83T and LVDS support msm: - Devfreq support for GPU tegra: - Prep work for adding Tegra186 support - Tegra186 HDMI support - HDMI2.0 and zpos support by using generic helpers tilcdc: - Misc fixes omapdrm: - Support memory bandwidth limits - DSI command mode panel cleanups - DMM error handling exynos: - drop the old IPP subdriver. etnaviv: - Occlusion query fixes - Job handling fixes - Prep work for hooking in gpu scheduler armada: - Move closer to atomic modesetting - Allow disabling primary plane if overlay is full screen imx: - Format modifier support - Add tile prefetch to PRE - Runtime PM support for PRG ast: - fix LUT loading" * tag 'drm-for-v4.16' of git://people.freedesktop.org/~airlied/linux: (1471 commits) drm/ast: Load lut in crtc_commit drm: Check for lessee in DROP_MASTER ioctl drm: fix gpu scheduler link order drm/amd/display: Demote error print to debug print when ATOM impl missing dma-buf: fix reservation_object_wait_timeout_rcu once more v2 drm/amdgpu: Avoid leaking PM domain on driver unbind (v2) drm/amd/amdgpu: Add Polaris version check drm/amdgpu: Reenable manual GPU reset from sysfs drm/amdgpu: disable MMHUB power gating on raven drm/ttm: Don't unreserve swapped BOs that were previously reserved drm/ttm: Don't add swapped BOs to swap-LRU list drm/amdgpu: only check for ECC on Vega10 drm/amd/powerplay: Fix smu_table_entry.handle type drm/ttm: add VADDR_FLAG_UPDATED_COUNT to correctly update dma_page global count drm: Fix PANEL_ORIENTATION_QUIRKS breaking the Kconfig DRM menuconfig drm/radeon: fill in rb backend map on evergreen/ni. drm/amdgpu/gfx9: fix ngg enablement to clear gds reserved memory (v2) drm/ttm: only free pages rather than update global memory count together drm/amdgpu: fix CPU based VM updates drm/amdgpu: fix typo in amdgpu_vce_validate_bo ...
When saving BOs in the hang state we skip one entry of the
kernel_state->bo[] array, thus leaving it to NULL. This leads to a NULL
pointer dereference when, later in this function, we iterate over all
BOs to check their ->madv state.

If the frame samples from a render target that was just written, its
cache flush during the binning step may have occurred before the
previous frame's RCL was completed. Flush the texture caches again
before starting each RCL job to make sure that the sampling of the
previous RCL's output is correct.

Linux 4.15-rc8 Daniel requested this for so the intel CI won't fall over on drm-next so often.
We were calling enable_irq on bind, where it was already enabled previously
by the IRQ helper. Additionally, dev->irq is not set correctly until after
postinstall and so was always zero here, triggering a warning in 4.15.
Fix both by moving the enable to the power management resume path, where we
know there was a previous disable invocation during suspend.

Use drm_fb_cma_fbdev_init() and drm_fb_cma_fbdev_fini() which relies on the fact that drm_device holds a pointer to the drm_fb_helper structure. This means that the driver doesn't have to keep track of that. Also use the drm_fb_helper functions directly.

With CONFIG_REFCOUNT_FULL enabled, refcount_inc() complains when it's
passed a refcount object that has its counter set to 0. In this driver,
this is a valid use case since we want to increment ->usecnt only when
the BO object starts to be used by real HW components and this is
definitely not the case when the BO is created.
Fix the problem by using refcount_inc_not_zero() instead of
refcount_inc() and fallback to refcount_set(1) when
refcount_inc_not_zero() returns false. Note that this 2-steps operation
is not racy here because the whole section is protected by a mutex
which guarantees that the counter does not change between the
refcount_inc_not_zero() and refcount_set() calls.
