2017-06-14drm: introduce sync objects (v4)Dave Airlie2-0/+15
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.

2017-06-05drm/bridge: Refactor out the panel wrapper from the lvds-encoder bridge.Eric Anholt1-0/+6
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.

2017-05-08drm/pl111: Initial drm/kms driver for pl111Tom Cooksey2-0/+7
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.

2017-04-04drm: document drm_ioctl.[hc]Daniel Vetter2-50/+14
Also unify/merge with the existing stuff. I was a bit torn where to put this, but in the end I decided to put all the ioctl/sysfs/debugfs stuff into drm-uapi.rst. That means we have a bit a split with the other uapi related stuff used internally, like drm_file.[hc], but I think overall this makes more sense. If it's too confusing we can always add more cross-links to make it more discoverable. But the auto-sprinkling of links kernel-doc already does seems sufficient. Also for prettier docs and more cross-links, switch the internal defines over to an enum, as usual. v2: Update kerneldoc fro drm_compat_ioctl too (caught by 0day), plus a bit more drive-by polish. v3: Fix typo, spotted by xerpi on irc (Sergi). v4: Add missing space in comment (Neil).

SCDC is a mechanism defined in the HDMI 2.0 specification that allows the source and sink devices to communicate.

First overview text (if there is any), then headers (since generally you want to start out with the data structures), then all the other stuff with functions.

2017-03-14drm/doc: Document drm_file.[hc]Daniel Vetter2-49/+7
Well, mostly drm_file.h, and clean up all related things: - I didnt' figure out the difference between preclose and postclose. The existing explanation in drm-internals.rst didn't convince me, since it's also really outdated - we clean up pending DRM events in the core nowadays. I put a FIXME in for the future. - Another FIXME is to have a macro for default fops. - Lots of links all around, main areas are to tie the overview in drm_file.c more into the callbacks in struct drm_device, and the other is to link render/primary node code to the right sections in drm-uapi.rst. - Also moved the open/close stuff to drm_drv.h from drm-internals.rst, seems like the better place for that information. Since that section was rather outdated this amounted to full-on rewrite. A big missing piece here is some overview graph, but I think better to wait with that one until drm_device and drm_driver are also fully documented. v2: Nits from Sean.

For consistency with other reference counting APIs in the kernel, add drm_gem_object_get() and drm_gem_object_put(), as well as an unlocked variant of the latter, to reference count GEM buffer objects. Compatibility aliases are added to keep existing code working. To help speed up the transition, all the instances of the old functions in the DRM core are already replaced in this commit.
