2016-07-13drm: Resurrect atomic rmfb codeDaniel Vetter
This was somehow lost between v3 and the merged version in Maarten's patch merged as: commit f2d580b9a8149735cbc4b59c4a8df60173658140 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.

2016-07-12drm/imx: store internal bus configuration in crtc statePhilipp Zabel
The internal bus configuration is imx-drm specific crtc state. Store it in imx_crtc_state and let the encoder atomic_check callbacks determine bus_flags, bus_format and the sync pins, possibly taking into account the mode and the connector display info. The custom imx_drm_encoder structure can be replaced again with drm_encoder. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>

2016-07-12drm/imx: atomic phase 3 step 2: Legacy callback fixupsLiu Ying
Now that we can use atomic configurations, all the legacy callbacks of CRTCs, encoders and connectors can be switched to the atomic version. For the imx-ldb driver, there is a clock parent setting mismatch bewteen ->enable and ->disable after the switch, so a fixup is added. For the imx-tve driver, since the encoder's callback ->dpms is replaced by ->disable, we need to move the setting for the IPU_CLK_EN bit(in register TVE_COM_CONF_REG) from ->enable/->disable to ->mode_set, otherwise, the relevant CRTC cannot be disabled correctly with a warning on DC stop timeout.

2016-07-12drm/bridge: dw-hdmi: Remove the legacy drm_connector_funcs structureLiu Ying
There is no one using the legacy drm_connector_funcs structure since the imx-drm has been converted to atomic, so we may remove it. Signed-off-by: Liu Ying <gnuiyl@gmail.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2016-07-12drm/imx: atomic phase 3 step 1: Use atomic configurationLiu Ying
Replacing drm_crtc_helper_set_config() by drm_atomic_helper_set_config() and converting the suspend/resume operations to atomic make us be able to use atomic configurations. All of these allow us to remove the crtc_funcs->mode_set callback as it is no longer used. Also, change the plane_funcs->update/disable_plane callbacks from the transitional version to the atomic version. Furthermore, switching to the pure atomic version of set_config callback means that we may implement CRTC/plane atomic checks by using the new CRTC/plane states instead of the legacy ones and we may remove the private ipu_crtc->enabled state which was left there for the transitional atomic helpers in phase 1. Page flip is also switched to the atomic version. Last, the legacy function drm_helper_disable_unused_functions() is removed from ->load in order not to confuse the atomic driver.

2016-07-12drm/imx: Remove encoders' ->prepare callbacksLiu Ying
The main task of imx encoders' ->prepare callbacks is to set bus_format, bus_flags, di_vsync_pin and di_hsync_pin. We may create a structure named imx_encoder to cache them. The atomic encoder callback ->disable may replace ->prepare later, so let's remove ->prepare.

2016-07-12drm/imx: atomic phase 1: Use transitional atomic CRTC and plane helpersLiu Ying
Use the drm_plane_helper_update/disable() and drm_helper_crtc_mode_set() transitional atomic helpers. The crtc->mode_set_nofb callback is added so that the primary plane is no longer tied to the CRTC. Check/update logics are separated to make sure crtc->mode_set_nofb and plane->atomic_update are always successful. Also, some necessary logics are tweaked for a smooth transition.

2016-07-12gpu: ipu-v3: ipu-dmfc: Use static DMFC FIFO allocation mechanismLiu Ying
For all video modes we support currently, we always get 2 slots for a plane by using the current existing dynamic DMFC FIFO allocation mechanism. So, let's change to use the static one to simplify the code. This also makes it easier to implement the atomic mode setting as we don't need to handle allocation failure cases then.

2016-07-12drm: Restore double clflush on the last partial cachelineChris Wilson
This effectively reverts commit afcd950cafea6e27b739fe7772cbbeed37d05b8b 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: afcd950cafea6 (drm: Avoid the double clflush on the last cache...)

2016-07-12drm/qxl: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar
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.

2016-07-12drm: Unexport drm_connector_register_all()Chris Wilson
This has now been removed from all drivers as it is performed centrally as a part of device registration for modesetting drivers. With the last user gone, we can unexport it from the DRM module.

2016-07-12drm/exynos: make fbdev support really optionalTobias Jakobi
Currently enabling Exynos DRM support automatically pulls in lots of fbdev dependencies. However these deps are unnecessary since DRM core already enables them when needed.

2016-07-12drm: Only handle _DRM_VBLANK_NEXTONMISS onceMichel Dänzer
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: Michel Dänzer <michel.daenzer@amd.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1466755187-29418-1-git-send-email-michel@daenzer.net
2016-07-12drm/vgem: Enable dmabuf interface for exportChris Wilson
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: Chris Wilson <chris@chris-wilson.co.uk> Cc: Sean Paul <seanpaul@chromium.org> Cc: Zach Reizner <zachr@google.com> Acked-by: Zach Reizner <zachr@google.com> Reviewed-by: Matthew Auld <matthew.auld@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1468242488-1505-3-git-send-email-chris@chris-wilson.co.uk
