2021-09-05utils: Add a dump_framebuffer() methodHEADmasterLaurent Pinchart
Add a new method to write the contents of a framebuffer to a file descriptor. This can be used to capture frames from writeback connectors. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2021-09-05card: Add support for writeback connectorsLaurent Pinchart
Enable enumeration of writeback connectors if both libdrm and the device support it. The new Card::has_writeback() method report if the card support writeback connectors. Existing code that expect all connectors to model an output may be confused by the sudden availability of new connectors. To handle this issue, - add a KMSXX_DISABLE_WRITEBACK_CONNECTORS environment variable to disable enumeration of writeback connectors, similarly to universal planes ; and - ignore writeback connectors where no specific connector is requested (Card::get_first_connected_connector(), ResourceManager::reserve_connector() if no connector name is specified, and applications that use all connected outputs).

2020-05-15resmgr: add release() methodsMatt Hoosier
This makes the ResourceManager class much more functional for uses where the set of resources used to scan out a scene changes from frame to frame. The atomic modesetting API discipline requires a brute-force search to find a compatible pairing of planes/etc, and being able to reserve bits incrementally is much simpler than throwing out the entire resourcemanager and make a new one each time a resource reserved in a tentative attempt to probe its compatibility with an test-mode atomic commit, turns out not to pan out.

2019-09-16videodevice: handle NV12 <-> NM12 translationBenoit Parrot
V4L2 and DRM differ in their interpretation of YUV420::NV12 V4L2 NV12 is a Y and UV co-located planes in a single plane buffer. DRM NV12 is a Y and UV planes presented as dual plane buffer, which is known as NM12 in V4L2. Since here we have hybrid DRM/V4L2 user space helper functions we need to translate DRM::NV12 to V4L2:NM12 pixel format back and forth to keep the data view consistent.

2017-10-03Rework framebuffer classesTomi Valkeinen
Drop (I)MappedFramebuffer, as it doesn't really provide any value, and have most of the methods be present in IFramebuffer with default exception throwing implementation. This gives us simpler way to use the framebuffers, as almost always we can just use a pointer to IFramebuffer.
