VKMS driver would be useful for testing, or for running X (or similar) on headless machines and be able to still use the GPU.

2018-07-04drm/i915/gtt: Pull global wc page stash under its own lockingChris Wilson
Currently, the wc-stash used for providing flushed WC pages ready for constructing the page directories is assumed to be protected by the struct_mutex. However, we want to remove this global lock and so must install a replacement global lock for accessing the global wc-stash (the per-vm stash continues to be guarded by the vm). We need to push ahead on this patch due to an oversight in hastily removing the struct_mutex guard around the igt_ppgtt_alloc selftest. No matter, it will prove very useful (i.e. will be required) in the near future. v2: Restore the onstack stash so that we can drop the vm->mutex in future across the allocation. v3: Restore the lost pagevec_init of the onstack allocation, and repaint function names. v4: Reorder init so that we don't try and use i915_address_space before it is ininitialised.

2018-07-04drm/i915: Fix pre-ILK error interrupt ackVille Syrjälä
Adjust the EIR clearing to cope with the edge triggered IIR on i965/g4x. To guarantee an edge in the ISR master error bit we temporarily mask everything in EMR. As some of the EIR bits can't even be directly cleared we also borrow a trick from i915_clear_error_registers() and permanently mask any bit that remains high. No real thought given to how we might unmask them again once the cause for the error has been clered. I suppose on pre-g4x GPU reset will reinitialize EMR from scratch.

Unfortunately we can't borrow the PIPESTAT trick and toggle the enable bits in PORT_HOTPLUG_EN as that act itself generates hotplug interrupts.

2018-07-03drm/i915/selftests: Release the struct_mutex to free the objectsChris Wilson
live_gtt is a very slow test to run, simply because it tries to allocate and use as much as the 48b address space as possibly can and in the process will try to own all of the system memory. This leads to resource exhaustion and CPU starvation; the latter impacts us when the NMI watchdog declares a task hung due to a mutex contention with ourselves. This we can prevent by releasing the struct_mutex and forcing our i915/rcu workers to run, and in particular flushing the freed object worker that is the cause for concern.

2018-07-03drm/vmwgfx: Fix atomic mode set checkSinclair Yeh
vmw_kms_atomic_check_modeset() is currently checking config using the legacy state, which is updated after a commit has happened. This means vmw_kms_atomic_check_modeset() will reject an invalid config on the next update rather than the current one. Fix this by using the new states for config checking Signed-off-by: Sinclair Yeh <syeh@vmware.com> Reviewed-by: Deepak Rawat <drawat@vmware.com> Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com>
2018-07-03drm/vmwgfx: Use blocking buffer object reserves when evicting resourcesThomas Hellstrom
Previously when evicting resources we were unconditionally calling ttm_eu_reserve_buffers with a NULL ww acquire context. That meant all buffer object reserves were done using trylock semantics. That makes sense when evicting during resource validation, because then there already are a number of buffers reserved and using waiting locks would cause lockdep errors. That's not the case when unconditionally evicting all resources as part of driver takedown or hibernation, so in that code path, make sure we have a ww acquire context to get waiting lock buffer object reserve semantics.

2018-07-03drm/vmwgfx: Optimize the buffer object swap_notify callback somewhat.Thomas Hellstrom
Only try to unmap cached maps when the buffer is moved into or out from vram. Otherwise the underlying pages stay the same. Also when unbinding resources from MOBs about to move, make sure we're really moving out of MOB memory.

2018-07-03drm/vmwgfx: Move buffer object related code to vmwgfx_bo.cThomas Hellstrom
It makes more sense to have all the buffer object related code in a single file rather than splitting it up between the resource code and buffer object pinning utilities. Place all buffer object related code in vmwgfx_bo.c. Fix up headers and export resource functionality when needed in the buffer object code.

2018-07-03drm/vmwgfx: Replace vmw_dma_buffer with vmw_buffer_objectThomas Hellstrom
Initially vmware buffer objects were only used as DMA buffers, so the name DMA buffer was a natural one. However, currently they are used also as dumb buffers and MOBs backing guest backed objects so renaming them to buffer objects is logical. Particularly since there is a dmabuf subsystem in the kernel where a dma buffer means something completely different. This also renames user-space api structures and IOCTL names correspondingly, but the old names remain defined for now and the ABI hasn't changed. There are a couple of minor style changes to make checkpatch happy.
