drm: define drm_compat_ioctl NULL on CONFIG_COMPAT=n and reduce #ifdefs

2016-11-02T15:33:47Z

If we define drm_compat_ioctl NULL on CONFIG_COMPAT=n, we don't have to check for the config everywhere. Reviewed-by: Patrik Jakobsson Signed-off-by: Jani Nikula Signed-off-by: Sean Paul Link: http://patchwork.freedesktop.org/patch/msgid/1478014844-27454-1-git-send-email-jani.nikula@intel.com

drm: Add reference counting to drm_atomic_state

2016-10-17T06:19:57Z

drm_atomic_state has a complicated single owner model that tracks the single reference from allocation through to destruction on another thread - or perhaps on a local error path. We can simplify this tracking by using reference counting (at a cost of a few more atomics). This is even more beneficial when the lifetime of the state becomes more convoluted than being passed to a single worker thread for the commit. v2: Double check !intel atomic_commit functions for missing gets v3: Update kerneldocs Signed-off-by: Chris Wilson Cc: Daniel Vetter Cc: dri-devel@lists.freedesktop.org Reviewed-by: Eric Engestrom Reviewed-by: Sean Paul Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/20161014121833.439-27-chris@chris-wilson.co.uk

drm: Don't swallow error codes in drm_dev_alloc()

2016-09-22T11:03:48Z

There are many reasons other than ENOMEM that drm_dev_init() can fail. Return ERR_PTR rather than NULL to be able to distinguish these in the caller. Signed-off-by: Tom Gundersen Signed-off-by: Sean Paul Link: http://patchwork.freedesktop.org/patch/msgid/20160921145919.13754-2-teg@jklm.no

drm/atomic-helper: Add NO_DISABLE_AFTER_MODESET flag support for plane commit

2016-08-29T09:29:37Z

Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter of the helper drm_atomic_helper_commit_planes() if the relevant display controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes when the CRTC is disabled. The helper would skip the ->atomic_disable call for a plane if the CRTC of the old plane state needs a modesetting operation. Of course, the drivers need to disable the planes in their CRTC disable callbacks since no one else would do that.

Merge tag 'drm/tegra/for-4.8-rc1' of git://anongit.freedesktop.org/tegra/linux into drm-next

2016-07-16T01:23:50Z

drm/tegra: Changes for v4.8-rc1 This set of changes contains a bunch of cleanups to the host1x driver as well as the addition of a pin controller for DPAUX, which is required by boards to configure the DPAUX pads in AUX mode (for DisplayPort) or I2C mode (for HDMI and DDC). Included is also a bit of rework of the SOR driver in preparation to add DisplayPort support as well as some refactoring and cleanup. Finally, all output drivers are converted to runtime PM, which greatly simplifies the handling of clocks and resets. * tag 'drm/tegra/for-4.8-rc1' of git://anongit.freedesktop.org/tegra/linux: (35 commits) drm/tegra: sor: Reject HDMI 2.0 modes drm/tegra: sor: Prepare for generic PM domain support drm/tegra: dsi: Prepare for generic PM domain support drm/tegra: sor: Make XBAR configurable per SoC drm/tegra: sor: Use sor1_src clock to set parent for HDMI dt-bindings: display: tegra: Add source clock for SOR drm/tegra: sor: Implement sor1_brick clock drm/tegra: sor: Implement runtime PM drm/tegra: hdmi: Implement runtime PM drm/tegra: dsi: Implement runtime PM drm/tegra: dc: Implement runtime PM drm/tegra: hdmi: Enable audio over HDMI drm/tegra: sor: Do not support deep color modes drm/tegra: sor: Extract tegra_sor_mode_set() drm/tegra: sor: Split out tegra_sor_apply_config() drm/tegra: sor: Rename tegra_sor_calc_config() drm/tegra: sor: Factor out tegra_sor_set_parent_clock() drm/tegra: dpaux: Add pinctrl support dt-bindings: Add bindings for Tegra DPAUX pinctrl driver drm/tegra: Prepare DPAUX for supporting generic PM domains ...

drm/tegra: dc: Implement runtime PM

2016-07-04T09:35:46Z

Use runtime PM to clock-gate, assert reset and powergate the display controller. This ties in nicely with atomic DPMS in that a runtime PM reference is taken before a pipe is enabled and dropped after it has been shut down. To make sure this works, make sure to only ever update planes on active CRTCs, otherwise register accesses to a clock-gated and reset CRTC will hang the CPU. Signed-off-by: Thierry Reding

drm/atomic-helper: Massage swap_state signature somewhat

2016-06-10T14:52:12Z

- dev is redundant, we have state->atomic - add stall parameter, which must be set when swapping needs to stall for preceeding commits to stop looking at ->state pointers. Currently all drivers need this to be, just prep work for a glorious future. v2: Rebased on top of commit e7cf0963f816fa44190caaf51aeffaa614c340c6 Author: Gerd Hoffmann Date: Tue May 31 08:50:47 2016 +0200 virtio-gpu: add atomic_commit function Cc: Gerd Hoffmann Reviewed-by: Maarten Lankhorst Cc: Maarten Lankhorst Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1465509992-19284-1-git-send-email-daniel.vetter@ffwll.ch Link: http://patchwork.freedesktop.org/patch/msgid/1465388359-8070-2-git-send-email-daniel.vetter@ffwll.ch

drm: Nuke ->vblank_disable_allowed

2016-05-20T21:03:31Z

This was added in commit 0a3e67a4caac273a3bfc4ced3da364830b1ab241 Author: Jesse Barnes Date: Tue Sep 30 12:14:26 2008 -0700 drm: Rework vblank-wait handling to allow interrupt reduction. to stay backwards-compatible with old UMS code that didn't even tell the kernel when it did a modeset, so that the kernel could save/restore vblank counters. At worst this means vblanks will be somewhat funky on a setup that very likely no one still runs. So let's just nuke it. Plan B would be to set it unconditionally in drm_vblank_init for kms drivers, instead of in each driver separately. So if this patch breaks anything please only restore the hunks in drmP.h and drm_irq.c, plus add a check for DRIVER_MODESET in drm_vblank_init. Stumbled over this in a discussion on irc with Chris.
