drm: Extract drm_mode_config.[hc]
And shuffle the kernel-doc structure a bit since drm_crtc.[hc] now only contains CRTC-related functions and structures. v2: - rebase onto drm-misc - don't forget to move drm_mode_config_cleanup. - move 2 internal decls under the right heading (Chris) Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>

|
||||||
* This can be shared PLLs, shared lanes, overall memory bandwidth,
|
|
||||||
* display fifo space (where shared between planes or maybe even
|
|
||||||
* CRTCs).
|
|
||||||
*
|
|
||||||
* - Checking that virtualized resources exported to userspace are not
|
|
||||||
* oversubscribed. For various reasons it can make sense to expose
|
|
||||||
* more planes, crtcs or encoders than which are physically there. One
|
|
||||||
* example is dual-pipe operations (which generally should be hidden
|
|
||||||
* from userspace if when lockstepped in hardware, exposed otherwise),
|
|
||||||
* where a plane might need 1 hardware plane (if it's just on one
|
|
||||||
* pipe), 2 hardware planes (when it spans both pipes) or maybe even
|
|
||||||
* shared a hardware plane with a 2nd plane (if there's a compatible
|
|
||||||
* plane requested on the area handled by the other pipe).
|
|
||||||
*
|
|
||||||
* - Check that any transitional state is possible and that if
|
|
||||||
* requested, the update can indeed be done in the vblank period
|
|
||||||
* without temporarily disabling some functions.
|
|
||||||
*
|
|
||||||
* - Check any other constraints the driver or hardware might have.
|
|
||||||
*
|
|
||||||
* - This callback also needs to correctly fill out the &drm_crtc_state
|
|
||||||
* in this update to make sure that drm_atomic_crtc_needs_modeset()
|
|
||||||
* reflects the nature of the possible update and returns true if and
|
|
||||||
* only if the update cannot be applied without tearing within one
|
|
||||||
* vblank on that CRTC. The core uses that information to reject
|
|
||||||
* updates which require a full modeset (i.e. blanking the screen, or
|
|
||||||
* at least pausing updates for a substantial amount of time) if
|
|
||||||
* userspace has disallowed that in its request.
|
|
||||||
*
|
|
||||||
* - The driver also does not need to repeat basic input validation
|
|
||||||
* like done for the corresponding legacy entry points. The core does
|
|
||||||
* that before calling this hook.

* This is the only hook to validate an atomic modeset update. This

|
* or driver doesn't support. This includes but is of course not limited
|
||||||
|
* to:
|
||||||
|
*
|
||||||
|
* - Checking that the modes, framebuffers, scaling and placement
|
||||||
|
* requirements and so on are within the limits of the hardware.
|
||||||
|
*
|
||||||
|
* - Checking that any hidden shared resources are not oversubscribed.
|
||||||
|
* This can be shared PLLs, shared lanes, overall memory bandwidth,
|
||||||
|
* display fifo space (where shared between planes or maybe even
|
||||||
|
* CRTCs).
|
||||||
|
*
|
||||||
|
* - Checking that virtualized resources exported to userspace are not
|
||||||
|
* oversubscribed. For various reasons it can make sense to expose
|
||||||
|
* more planes, crtcs or encoders than which are physically there. One
|
||||||
|
* example is dual-pipe operations (which generally should be hidden
|
||||||
|
* from userspace if when lockstepped in hardware, exposed otherwise),
|
||||||
|
* where a plane might need 1 hardware plane (if it's just on one
|
||||||
|
* pipe), 2 hardware planes (when it spans both pipes) or maybe even
|
||||||
|
* shared a hardware plane with a 2nd plane (if there's a compatible
|
||||||
|
* plane requested on the area handled by the other pipe).
|
||||||
|
*
|
||||||
|
* - Check that any transitional state is possible and that if
|
||||||
|
* requested, the update can indeed be done in the vblank period
|
||||||
|
* without temporarily disabling some functions.
|
||||||
|
*
|
||||||
|
* - Check any other constraints the driver or hardware might have.
|
||||||
|
*
|
||||||
|
* - This callback also needs to correctly fill out the &drm_crtc_state
|
||||||
|
* in this update to make sure that drm_atomic_crtc_needs_modeset()
|
||||||
|
* reflects the nature of the possible update and returns true if and
|
||||||
|
* only if the update cannot be applied without tearing within one
|
||||||
|
* vblank on that CRTC. The core uses that information to reject
|
||||||
|
* updates which require a full modeset (i.e. blanking the screen, or
|
||||||
|
* at least pausing updates for a substantial amount of time) if
|
||||||
|
* userspace has disallowed that in its request.
|
||||||
|
*
|
||||||
|
* - The driver also does not need to repeat basic input validation
|
||||||
|
* like done for the corresponding legacy entry points. The core does
|
||||||
|
* that before calling this hook.
|
||||||
|
