^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 2) Mode Setting Helper Functions
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3) =============================
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 4)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 5) The DRM subsystem aims for a strong separation between core code and helper
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6) libraries. Core code takes care of general setup and teardown and decoding
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) userspace requests to kernel internal objects. Everything else is handled by a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) large set of helper libraries, which can be combined freely to pick and choose
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) for each driver what fits, and avoid shared code where special behaviour is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) needed.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) This distinction between core code and helpers is especially strong in the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) modesetting code, where there's a shared userspace ABI for all drivers. This is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) in contrast to the render side, where pretty much everything (with very few
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) exceptions) can be considered optional helper code.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) There are a few areas these helpers can grouped into:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) * Helpers to implement modesetting. The important ones here are the atomic
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) helpers. Old drivers still often use the legacy CRTC helpers. They both share
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) the same set of common helper vtables. For really simple drivers (anything
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) that would have been a great fit in the deprecated fbdev subsystem) there's
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) also the simple display pipe helpers.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) * There's a big pile of helpers for handling outputs. First the generic bridge
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) helpers for handling encoder and transcoder IP blocks. Second the panel helpers
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) for handling panel-related information and logic. Plus then a big set of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) helpers for the various sink standards (DisplayPort, HDMI, MIPI DSI). Finally
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) there's also generic helpers for handling output probing, and for dealing with
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) EDIDs.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) * The last group of helpers concerns itself with the frontend side of a display
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) pipeline: Planes, handling rectangles for visibility checking and scissoring,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) flip queues and assorted bits.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 344) Strictly speaking this is not a DRM helper library but generally useable
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 345) by any driver interfacing with HDMI outputs like v4l or alsa drivers.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 346) But it nicely fits into the overall topic of mode setting helper
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 347) libraries and hence is also included here.
