linux/drivers/gpu/drm/msm, branch v3.19

Merge branch 'msm-fixes-3.19' of git://people.freedesktop.org/~robclark/linux into drm-fixes

2014-12-22T22:21:54Z

A few msm fixes for 3.19: * hdmi regulators fix * hdmi fix for spurious HPD interrupts * fix for sync atomic update after async update (which could show up with a setcrtc following a pageflip) * couple little Coccinelle cleanups * 'msm-fixes-3.19' of git://people.freedesktop.org/~robclark/linux: drm/msm/hdmi: rework HDMI IRQ handler drm/msm/hdmi: enable regulators before clocks to avoid warnings drm/msm/mdp5: update irqs on crtc<->encoder link change drm/msm: block incoming update on pending updates drm/msm: Deletion of unnecessary checks before the function call "release_firmware" drm/msm: Deletion of unnecessary checks before two function calls

drm/msm/hdmi: rework HDMI IRQ handler

2014-12-18T19:32:15Z

Disable the HPD interrupt when acking it, to avoid spurious interrupt. Signed-off-by: Jilai Wang

drm/msm/hdmi: enable regulators before clocks to avoid warnings

2014-12-18T19:32:15Z

HPD regulators need to be enabled before clocks, otherwise clock driver will report warning. Signed-off-by: Jilai Wang

drm/msm/mdp5: update irqs on crtc<->encoder link change

2014-12-18T19:32:14Z

If crtc <-> encoder linkage changes, we could end up with the CRTC listening for the wrong error or vsync irqs. Generally this problem would correct itself relatively quickly, since we update the global irqmask after dispatching irqs, but to be sure let the CRTC trigger update_irq(). Signed-off-by: Rob Clark

drm/msm: block incoming update on pending updates

2014-12-18T19:32:14Z

We can't have multiple updates pending on a given CRTC, and we don't want a sync update to race w/ an async update that preceeded it. So keep track of which CRTCs have updates in flight, and block later updates that would conflict. Signed-off-by: Rob Clark

drm/msm: Deletion of unnecessary checks before the function call "release_firmware"

2014-12-17T15:59:49Z

The release_firmware() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Reviewed-by: Thierry Reding Signed-off-by: Rob Clark

drm/msm: Deletion of unnecessary checks before two function calls

2014-12-17T15:59:49Z

The functions framebuffer_release() and vunmap() perform also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Reviewed-by: Thierry Reding Signed-off-by: Rob Clark

Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux

2014-12-15T23:52:01Z

Pull drm updates from Dave Airlie: "Highlights: - AMD KFD driver merge This is the AMD HSA interface for exposing a lowlevel interface for GPGPU use. They have an open source userspace built on top of this interface, and the code looks as good as it was going to get out of tree. - Initial atomic modesetting work The need for an atomic modesetting interface to allow userspace to try and send a complete set of modesetting state to the driver has arisen, and been suffering from neglect this past year. No more, the start of the common code and changes for msm driver to use it are in this tree. Ongoing work to get the userspace ioctl finished and the code clean will probably wait until next kernel. - DisplayID 1.3 and tiled monitor exposed to userspace. Tiled monitor property is now exposed for userspace to make use of. - Rockchip drm driver merged. - imx gpu driver moved out of staging Other stuff: - core: panel - MIPI DSI + new panels. expose suggested x/y properties for virtual GPUs - i915: Initial Skylake (SKL) support gen3/4 reset work start of dri1/ums removal infoframe tracking fixes for lots of things. - nouveau: tegra k1 voltage support GM204 modesetting support GT21x memory reclocking work - radeon: CI dpm fixes GPUVM improvements Initial DPM fan control - rcar-du: HDMI support added removed some support for old boards slave encoder driver for Analog Devices adv7511 - exynos: Exynos4415 SoC support - msm: a4xx gpu support atomic helper conversion - tegra: iommu support universal plane support ganged-mode DSI support - sti: HDMI i2c improvements - vmwgfx: some late fixes. - qxl: use suggested x/y properties" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (969 commits) drm: sti: fix module compilation issue drm/i915: save/restore GMBUS freq across suspend/resume on gen4 drm: sti: correctly cleanup CRTC and planes drm: sti: add HQVDP plane drm: sti: add cursor plane drm: sti: enable auxiliary CRTC drm: sti: fix delay in VTG programming drm: sti: prepare sti_tvout to support auxiliary crtc drm: sti: use drm_crtc_vblank_{on/off} instead of drm_vblank_{on/off} drm: sti: fix hdmi avi infoframe drm: sti: remove event lock while disabling vblank drm: sti: simplify gdp code drm: sti: clear all mixer control drm: sti: remove gpio for HDMI hot plug detection drm: sti: allow to change hdmi ddc i2c adapter drm/doc: Document drm_add_modes_noedid() usage drm/i915: Remove '& 0xffff' from the mask given to WA_REG() drm/i915: Invert the mask and val arguments in wa_add() and WA_REG() drm: Zero out DRM object memory upon cleanup drm/i915/bdw: Fix the write setting up the WIZ hashing mode ...

drm/plane: Pass old state to ->atomic_update()

2014-11-25T12:27:58Z

In most situations it will be useful to have the old state passed to the ->atomic_update() callback. For example if a plane is being disabled the new state's .crtc field will be NULL, but some drivers may rely on this field to program the CRTCs registers. v2: rename variable to old_plane_state and remove redundant comment as suggested by Daniel Vetter, remove an Exynos hunk that doesn't apply to drm-next and add a hunk for pending MSM mdp5 changes Reviewed-by: Daniel Vetter Signed-off-by: Thierry Reding Signed-off-by: Daniel Vetter
