2016-05-08drm: msm: remove unused variableArnd Bergmann1-1/+0
A recent cleanup removed the only user of the 'kms' variable in msm_preclose(), causing a harmless compiler warning: drivers/gpu/drm/msm/msm_drv.c: In function 'msm_preclose': drivers/gpu/drm/msm/msm_drv.c:468:18: error: unused variable 'kms' [-Werror=unused-variable] This removes the variable as well.

2016-05-08drm/msm: fix ->last_fence() after recoverRob Clark1-2/+2
It is no longer true that we discard all in-flight submits on recover (these days we only discard the first one that hung). After the first re-submitted batch completes it would overwrite the fence with a correct value, but there would be a window of time which showed all re-submitted batches as already complete.

2016-05-08drm/msm: remove fence_cbsRob Clark6-107/+47
This was only used for atomic commit these days. So instead just give atomic it's own work-queue where we can do a block on each bo in turn. Simplifies things a whole bunch and makes the 'struct fence' conversion easier. Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-05-08drm/msm: introduce msm_fence_contextRob Clark9-78/+108

2016-05-08drm/msm: split locking and pinning BO'sRob Clark2-31/+40
Split up locking and pinning buffers in the submit path. This is needed because we'll want to insert fencing in between the two steps. This makes things end up looking more similar to etnaviv submit code (which was originally modelled on the msm code but has already added 'struct fence' support).

Add an indirect object operations call to allow distinct implementations of the mmap operation based on the type of the object.

2016-05-05drm/fsl-dcu: use bus_flags for pixel clock polarityStefan Agner3-3/+9
The drivers current default configuration drives the pixel data on rising edge of the pixel clock. However, most display sample data on rising edge... This leads to color shift artefacts visible especially at edges. This patch changes the relevant defines to be useful and actually set the bits, and changes pixel clock polarity to drive the pixel data on falling edge by default. The patch also adds an explicit pixel clock polarity flag to the display introduced with the driver (NEC WQVGA "nec,nl4827hc19-05b") using the new bus_flags field to retain the initial behavior.

2016-05-05drm/radeon: fix DP link training issue with second 4K monitorArindam Nath1-1/+1
There is an issue observed when we hotplug a second DP 4K monitor to the system. Sometimes, the link training fails for the second monitor after HPD interrupt generation. The issue happens when some queued or deferred transactions are already present on the AUX channel when we initiate a new transcation to (say) get DPCD or during link training. We set AUX_IGNORE_HPD_DISCON bit in the AUX_CONTROL register so that we can ignore any such deferred transactions when a new AUX transaction is initiated.

2016-05-05drm/core: Do not preserve framebuffer on rmfb, v4.Maarten Lankhorst1-7/+56
It turns out that preserving framebuffers after the rmfb call breaks vmwgfx userspace. This was originally introduced because it was thought nobody relied on the behavior, but unfortunately it seems there are exceptions. drm_framebuffer_remove may fail with -EINTR now, so a straight revert is impossible. There is no way to remove the framebuffer from the lists and active planes without introducing a race because of the different locking requirements. Instead call drm_framebuffer_remove from a workqueue, which is unaffected by signals. Changes since v1: - Add comment. Changes since v2: - Add fastpath for refcount = 1. (danvet) Changes since v3: - Rebased. - Restore lastclose framebuffer removal too. Cc: stable@vger.kernel.org #v4.4+ Fixes: 13803132818c ("drm/core: Preserve the framebuffer after removing it.")
