drm/tegra: dc: Support rotation property

2018-05-18T19:56:21Z

Currently only the DRM_MODE_REFLECT_Y rotation is supported. The driver already supports reflection on the Y axis via a custom flag which is not very useful because it requires custom userspace. Add the standard rotation property that supports 0 degree rotation and Y axis reflection for primary and overlay planes to provide a better interface than the custom flag. v2: keep custom flag for ABI compatibility (Dmitry) Reviewed-by: Dmitry Osipenko Tested-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: plane: Implement zpos plane property for older Tegras

2018-05-17T12:08:44Z

Older Tegra's do not support plane's Z position handling in hardware, but the hardware provides knobs to implement it in software. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

Backmerge tag 'v4.16-rc7' into drm-next

Linux 4.16-rc7 This was requested by Daniel, and things were getting a bit hard to reconcile, most of the conflicts were trivial though.

Merge tag 'drm/tegra/for-4.17-rc1' of git://anongit.freedesktop.org/tegra/linux into drm-next

2018-03-21T04:04:38Z

drm/tegra: Changes for v4.17-rc1 This fixes mmap() for fbdev devices by providing a custom implementation based on the KMS variant. This is a fairly exotic case these days, hence why it is not flagged for stable. There is also support for dedicating one of the overlay planes to serve as a hardware cursor on older Tegra that did support hardware cursors but not RGBA formats for it. Planes will now also export the IN_FORMATS property by supporting the various block-linear tiling modifiers for RGBA pixel formats. Other than that, there's a bit of cleanup of DMA API abuse, use of the private object infrastructure for global state (rather than subclassing atomic state objects) and an implementation of ->{begin,end}_cpu_access callbacks for PRIME exported buffers, which allow users to perform cache maintenance on these buffers. * tag 'drm/tegra/for-4.17-rc1' of git://anongit.freedesktop.org/tegra/linux: drm/tegra: prime: Implement ->{begin,end}_cpu_access() drm/tegra: gem: Map pages via the DMA API drm/tegra: hub: Use private object for global state drm/tegra: fb: Properly support linear modifier drm/tegra: plane: Support format modifiers drm/tegra: dc: Dedicate overlay plane to cursor on older Tegra's drm/tegra: plane: Make tegra_plane_get_overlap_index() static drm/tegra: fb: Implement ->fb_mmap() callback drm/tegra: gem: Make __tegra_gem_mmap() available more widely drm/tegra: gem: Reshuffle declarations

drm/tegra: plane: Support format modifiers

2018-03-15T18:06:11Z

Pass the list of valid format modifiers to planes upon initialization and implement the ->format_mod_supported() callback so that userspace can query for the valid combinations of formats and modifiers. Signed-off-by: Thierry Reding

drm/tegra: plane: Correct legacy blending

2018-03-15T14:56:46Z

drm/tegra: plane: Fix RGB565 format on older Tegra

2018-03-15T10:33:47Z

The opaque/alpha format conversion code is currently only looking at XRGB formats because they have an equivalent ARGB format. The opaque format for RGB565 is RGB565 itself, much like the YUV formats map to themselves.

drm/tegra/dc: Use drm_mode_get_hv_timing() to populate plane clip rectangle

2018-01-23T15:58:56Z

Use drm_mode_get_hv_timing() to fill out the plane clip rectangle. No functional changes as the code already uses crtc_state->mode to populate the clip, which is also what drm_mode_get_hv_timing() uses. Once everyone agrees on this we can move the clip handling into drm_atomic_helper_check_plane_state(). v2: Rebase due to tegra_plane_state_add() relocating to plane.c Cc: Laurent Pinchart Cc: Thierry Reding Cc: linux-tegra@vger.kernel.org Signed-off-by: Ville Syrjälä Acked-by: Thierry Reding Reviewed-by: Thierry Reding Link: https://patchwork.freedesktop.org/patch/msgid/20171123190502.28449-13-ville.syrjala@linux.intel.com
