drm: introduce sync objects (v4)

2017-06-14T02:10:22+00:00

Sync objects are new toplevel drm object, that contain a pointer to a fence. This fence can be updated via command submission ioctls via drivers. There is also a generic wait obj API modelled on the vulkan wait API (with code modelled on some amdgpu code). These objects can be converted to an opaque fd that can be passes between processes. v2: rename reference/unreference to put/get (Chris) fix leaked reference (David Zhou) drop mutex in favour of cmpxchg (Chris) v3: cleanups from danvet, rebase on drm_fops rename check fd_flags is 0 in ioctls. v4: export find/free, change replace fence to take a syncobj. In order to support lookup first, replace later semantics which seem in the end to be cleaner. Reviewed-by: Sean Paul Reviewed-by: Chris Wilson Signed-off-by: Dave Airlie

drm/bridge: Refactor out the panel wrapper from the lvds-encoder bridge.

2017-06-05T08:30:40+00:00

Many DRM drivers have common code to make a stub connector implementation that wraps a drm_panel. By wrapping the panel in a DRM bridge, all of the connector code (including calls during encoder enable/disable) goes away. v2: Fix build with CONFIG_DRM=m, drop "dev" argument that should just be the panel's dev, move kerneldoc up a level and document _remove(). v3: Fix another breakage with CONFIG_DRM=m, fix breakage with CONFIG_OF=n, move protos under CONFIG_DRM_PANEL_BRIDGE, wrap a line.

drm: Extract drm_vblank.[hc]

drm_irq.c contains both the irq helper library (optional) and the vblank support (optional, but part of the modeset uapi, and doesn't require the use of the irq helpers at all. Split this up for more clarity of the scope of the individual bits. v2: Move misplaced hunks to this patch (Stefan).

drm/pl111: Initial drm/kms driver for pl111

2017-05-08T19:24:06+00:00

This is a modesetting driver for the pl111 CLCD display controller found on various ARM platforms such as the Versatile Express. The driver has only been tested on the bcm911360_entphn platform so far, with PRIME-based buffer sharing between vc4 and clcd. It reuses the existing devicetree binding, while not using quite as many of its properties as the fbdev driver does (those are left for future work). v2: Nearly complete rewrite by anholt, cutting 2/3 of the code thanks to DRM core's excellent new helpers. v3: Don't match pl110 any more, don't attach if we don't have a DRM panel, use DRM_GEM_CMA_FOPS, update MAINTAINERS, use the simple display helper, use drm_gem_cma_dumb_create (same as our wrapper). v4: Change the driver's .name to not clash with fbdev in sysfs, drop platform alias, drop redundant "drm" in DRM driver name, hook up .prepare_fb to the CMA helper so that DMA fences should work. v5: Move register definitions inside the driver directory, fix build in COMPILE_TEST and !AMBA mode. v6: Drop TIM2_CLKSEL for now to be consistent with existing DT bindings, switch back to external register definitions.

SCDC is a mechanism defined in the HDMI 2.0 specification that allows the source and sink devices to communicate. This commit introduces helpers to access the SCDC and provides the symbolic names for the various registers defined in the specification. V2: Rebase. V3: Added R-B from Jose.
