2018-07-05drm: mali-dp: Add RGB writeback formats for DP550/DP650Brian Starkey
Add a layer bit for the SE memory-write, and add it to the pixel format matrix for DP550/DP650. Signed-off-by: Brian Starkey <brian.starkey@arm.com> [rebased and fixed conflicts] Signed-off-by: Mihail Atanassov <mihail.atanassov@arm.com> Signed-off-by: Liviu Dudau <liviu.dudau@arm.com>
2018-07-05drm: mali-dp: Add support for writeback on DP550/DP650Liviu Dudau
Mali-DP display processors are able to write the composition result to a memory buffer via the SE. Add entry points in the HAL for enabling/disabling this feature, and implement support for it on DP650 and DP550. DP500 acts differently and so is omitted from this change.

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.

2018-07-03locking: Implement an algorithm choice for Wound-Wait mutexesThomas Hellstrom
The current Wound-Wait mutex algorithm is actually not Wound-Wait but Wait-Die. Implement also Wound-Wait as a per-ww-class choice. Wound-Wait is, contrary to Wait-Die a preemptive algorithm and is known to generate fewer backoffs. Testing reveals that this is true if the number of simultaneous contending transactions is small. As the number of simultaneous contending threads increases, Wait-Wound becomes inferior to Wait-Die in terms of elapsed time. Possibly due to the larger number of held locks of sleeping transactions. Update documentation and callers.

2018-07-03drm: add missing ctx argument to plane transitional helpersRussell King
In commits: 34a2ab5e0689 ("drm: Add acquire ctx parameter to ->update_plane") 1931529448bc ("drm: Add acquire ctx parameter to ->plane_disable") a pointer to a drm_modeset_acquire_ctx structure was added as an argument to the method prototypes. The transitional helpers are supposed to be directly plugged in as implementations of these methods, but doing so generates a warning. Add the missing argument. A number of buggy users were added for drm_plane_helper_disable() which need to be fixed up for this change, which we do by passing a NULL ctx argument.

2018-07-02dma-fence: Allow wait_any_timeout for all fencesDaniel Vetter
When this was introduced in commit a519435a96597d8cd96123246fea4ae5a6c90b02 Author: Christian König <christian.koenig@amd.com> Date: Tue Oct 20 16:34:16 2015 +0200 dma-buf/fence: add fence_wait_any_timeout function v2 there was a restriction added that this only works if the dma-fence uses the dma_fence_default_wait hook. Which works for amdgpu, which is the only caller. Well, until you share some buffers with e.g. i915, then you get an -EINVAL. But there's really no reason for this, because all drivers must support callbacks. The special ->wait hook is only as an optimization; if the driver needs to create a worker thread for an active callback, then it can avoid to do that if it knows that there's a process context available already. So ->wait is just an optimization, just using the logic in dma_fence_default_wait() should work for all drivers. Let's remove this restriction.

2018-07-02dma-fence: Make ->enable_signaling optionalDaniel Vetter
Many drivers have a trivial implementation for ->enable_signaling. Let's make it optional by assuming that signalling is already available when the callback isn't present. v2: Don't do the trick to set the ENABLE_SIGNAL_BIT unconditionally, it results in an expensive spinlock take for everyone. Instead just check if the callback is present. Suggested by Maarten. Also move misplaced kerneldoc hunk to the right patch.

2018-07-01drm/pl111: Support Nomadik LCDC variantLinus Walleij
The Nomadik has a variant of the PL110 known as "Color LCD Controller" LCDC. This variant has the same bit ordering as the DRM subsystem (in difference from the other variants) and adds a few bits for the control of 5551, 565 etc in the control register. Notably it also adds a packed RGB888 24BPP mode. We add support by detecting this variant and also adding a small plug-in that will mux the LCDC out if the ASIC happens to be muxed to the other graphics controller (they are mutually exclusive).
