2018-07-05drm/vkms: Introduce basic VKMS driverHaneen Mohammed5-0/+169
This patch introduces Virtual Kernel Mode-Setting (VKMS) driver. It creates a very basic kms driver with 1 crtc/encoder/connector/plane. VKMS driver would be useful for testing, or for running X (or similar) on headless machines and be able to still use the GPU. Thus it enables a virtual display without the need for hardware display capability.

2018-07-05drm/etnaviv: bring back progress check in job timeout handlerLucas Stach2-0/+27
When the hangcheck handler was replaced by the DRM scheduler timeout handling we dropped the forward progress check, as this might allow clients to hog the GPU for a long time with a big job. It turns out that even reasonably well behaved clients like the Armada Xorg driver occasionally trip over the 500ms timeout. Bring back the forward progress check to get rid of the userspace regression. We would still like to fix userspace to submit smaller batches if possible, but that is for another day.

2018-07-05drm/udl: fix display corruption of the last lineMikulas Patocka2-5/+11
The displaylink hardware has such a peculiarity that it doesn't render a command until next command is received. This produces occasional corruption, such as when setting 22x11 font on the console, only the first line of the cursor will be blinking if the cursor is located at some specific columns. When we end up with a repeating pixel, the driver has a bug that it leaves one uninitialized byte after the command (and this byte is enough to flush the command and render it - thus it fixes the screen corruption), however whe we end up with a non-repeating pixel, there is no byte appended and this results in temporary screen corruption. This patch fixes the screen corruption by always appending a byte 0xAF at the end of URB. It also removes the uninitialized byte.

2018-07-04drm/i915/gtt: Pull global wc page stash under its own lockingChris Wilson7-85/+143
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.

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.

2018-07-03drm/i915/selftests: Release the struct_mutex to free the objectsChris Wilson1-0/+23
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.

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.

2018-07-03drm/i915: Try GGTT mmapping whole object as partialChris Wilson2-12/+18
If the whole object is already pinned by HW for use as scanout, we will fail to move it to the mappable region and so must resort to using a partial VMA covering the whole object.
