* drm/omap: print error instead of WARN() if plane setup failsTomi Valkeinen2016-11-021-1/+3
| | | | | | | | | | | | omap_plane_atomic_update() does WARN_ON() if dispc rejects the given plane config. Change that to dev_err() to lessen the possible spam. To fix this correctly, the plane setup needs much more work by creating a check function for dispc setup, so that we could reliably check the config in atomic_check, instead of only noticing the problem when programming dispc.

| | | | | | | | | | | | | | | | | | I sometimes see: [drm:drm_framebuffer_remove [drm]] *ERROR* failed to reset crtc ed2a6c00 when fb was deleted: -22 which comes from drm_framebuffer_remove() when it's disabling the crtc with zeroed drm_mode_set. The problem in omap_plane_atomic_check() is that it will use those zeroed fields to verify if the setup is correct. This patch makes omap_plane_atomic_check() return 0 if the crtc is disabled.

* drm: Add reference counting to drm_atomic_stateChris Wilson2016-10-171-1/+2
| | | | | | | | | | | | | | | | | | | | 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 <chris@chris-wilson.co.uk> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: dri-devel@lists.freedesktop.org Reviewed-by: Eric Engestrom <eric.engestrom@imgtec.com> Reviewed-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20161014121833.439-27-chris@chris-wilson.co.uk
* drm/atomic-helper: Add NO_DISABLE_AFTER_MODESET flag support for plane commitLiu Ying2016-08-291-1/+1
| | | | | | | | | | | | | | | | | | | | 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.

While developing and testing this patch things blew up in really interesting ways, and the code is rather confusing in naming things between the kernel code, ioctl #defines and libdrm. For the next brave dragon slayer, document all this madness properly in the userspace interface section of gpu.tmpl. v2: Make drm_dev_set_unique static and update kerneldoc. v3: Entire rewrite, plus document what's going on for posterity in the gpu docbook uapi section. v4: Drop accidental amdgpu hunk (Emil). v5: Drop accidental omapdrm vblank counter change (Emil). v6: Rebase on top of the sphinx conversion.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement gamma_lut atomic crtc properties, set crtc gamma size to 256 for all crtcs and use drm_atomic_helper_legacy_gamma_set() as gamma_set func. The tv-out crtc has 1024 element gamma table (with 10bit precision) in HW, but current Xorg server does not accept anything else but 256 elements so that is used for all CRTCs. The dss dispc API converts table of any length for HW and uses linear interpolation in the process. The default gamma table is restored if gamma_lut property is deleted.

The workaround sets up a minimal LCD setup with GFX plane and waits for one vertical sync irq before disabling the setup and continuing with the context restore. The physical outputs are gated during the operation. For details see: OMAP543x Multimedia Device Silicon Revision 2.0 Silicon Errata Literature Number: SWPZ037E Or some other relevant errata document for the DSS IP version.

DSS driver initializes the default gamma table at component bind time and holds a copy of all gamma tables in its internal data structure. Each call to dispc_mgr_set_gamma() updates the internal table and triggers write to the HW, if it is enabled. The tables are restored to HW in PM resume callback. The drivers internal data structure match the HW tables in size and in number of significant bits per color component. The dispc_mgr_set_gamma() converts the size of any given table for the internal data structure using linear interpolation. Default gamma table is restored if NULL is given in place of gamma lut. dispc_mgr_gamma_size() gives HW gamma table size for the channel and returns 0 if gamma table is not supported by the HW or the DSS driver.
