This was somehow lost between v3 and the merged version in Maarten's patch merged as: commit f2d580b9 Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Date: Wed May 4 14:38:26 2016 +0200 drm/core: Do not preserve framebuffer on rmfb, v4. Actual code copied from Maarten's patch, but with the slight change to just use dev->mode_config.funcs->atomic_commit to decide whether to use the atomic path or not.

This effectively reverts commit afcd950c Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Jun 10 15:58:01 2015 +0100 drm: Avoid the double clflush on the last cache line in drm_clflush_virt_range() as we have observed issues with serialisation of the clflush operations on Baytrail+ Atoms with partial updates. Applying the double flush on the last cacheline forces that clflush to be ordered with respect to the previous clflush, and the mfence then protects against prefetches crossing the clflush boundary. The same issue can be demonstrated in userspace with igt/gem_exec_flush. Fixes: afcd950c (drm: Avoid the double clflush on the last cache...)

System workqueues have been able to handle high level of concurrency for a long time now and there's no reason to use dedicated workqueues just to gain concurrency. Since the workqueue in the QXL graphics device driver is involved in freeing and processing the release ring (workitem &qdev->gc_workqxl, maps to gc_work which calls qxl_garbage_collect) and is not being used on a memory reclaim path, dedicated gc_queue has been replaced with the use of system_wq. Unlike a dedicated per-cpu workqueue created with create_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantees unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference. flush_work() has been called in qxl_device_fini() to ensure that there are no pending tasks while disconnecting the driver.

Consolidate the _DRM_VBLANK_NEXTONMISS handling between drm_wait_vblank and drm_queue_vblank_event. This is a cleanup spotted while working on other changes. (The way it was previously handled could also theoretically result in drm_queue_vblank_event unnecessarily bumping vblwait->request.sequence, if the vblank counter happened to increment between the drm_vblank_count(_and_time) calls in each function, but that's unlikely) Signed-off-by:

Enable the standard GEM dma-buf interface provided by the DRM core, but only for exporting the VGEM object. This allows passing around the VGEM objects created from the dumb interface and using them as sources elsewhere. Creating a VGEM object for a foriegn handle is not supported. v2: With additional completeness. v3: Need to clear the CPU cache upon exporting the dma-addresses. v4: Use drm_gem_put_pages() as well. v5: Use drm_prime_pages_to_sg() Testcase: igt/vgem_basic/dmabuf-* Testcase: igt/prime_vgem Signed-off-by:

The vGEM mmap code has bitrotted slightly and now immediately BUGs. Since vGEM was last updated, there are new core GEM facilities to provide more common functions, so let's use those here. v2: drm_gem_free_mmap_offset() is performed from drm_gem_object_release() so we can remove the redundant call.
