drm: Introduce plane and CRTC scaling filter properties

2020-10-21T09:19:54+00:00

Introduce per-plane and per-CRTC scaling filter properties to allow
userspace to select the driver's default scaling filter or
Nearest-neighbor(NN) filter for upscaling operations on CRTC and
plane.

Drivers can set up this property for a plane by calling
drm_plane_create_scaling_filter() and for a CRTC by calling
drm_crtc_create_scaling_filter().

NN filter works by filling in the missing color values in the upscaled
image with that of the coordinate-mapped nearest source pixel value.

NN filter for integer multiple scaling can be particularly useful for
for pixel art games that rely on sharp, blocky images to deliver their
distinctive look.

changes since: v6:
* Move property doc to existing "Standard CRTC Properties" and
  "Plane Composition Properties" doc comments (Simon)
changes since v3:
* Refactor code, add new function for common code (Ville)
changes since v2:
* Create per-plane and per-CRTC scaling filter property (Ville)
changes since v1:
* None
changes since RFC:
* Add separate properties for plane and CRTC (Ville)

drm/modeset-lock: Take the modeset BKL for legacy drivers

2020-08-17T17:41:50+00:00

This fell off in the conversion in

commit 9bcaa3fe58ab7559e71df798bcff6e0795158695

    drm: Replace drm_modeset_lock/unlock_all with DRM_MODESET_LOCK_ALL_* helpers

but it's caught by the drm_warn_on_modeset_not_all_locked() that the
legacy modeset code uses. Since this is the bkl and it's unclear
what's all protected, play it safe and grab it again for legacy
drivers.

Unfortunately this means we need to sprinkle a few more #includes
around.

Also we need to add the drm_device as a parameter to the _END macro.

Finally remove the mute_lock() from setcrtc, since that's now done by
the macro.

drm: no need to check return value of debugfs_create functions

2019-06-13T14:39:16+00:00

When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

Because there is no need to check these functions, a number of local
functions can be made to return void to simplify things as nothing can
fail.

drm/lease: Make sure implicit planes are leased

2019-04-24T09:30:32+00:00

If userspace doesn't enable universal planes, then we automatically
add the primary and cursor planes. But for universal userspace there's
no such check (and maybe we only want to give the lessee one plane,
maybe not even the primary one), hence we need to check for the
implied plane.

v2: don't forget setcrtc ioctl.

v3: Still allow disabling of the crtc in SETCRTC.

drm: Move the legacy kms disable_all helper to crtc helpers

2019-01-11T21:54:29+00:00

It's not a core function, and the matching atomic functions are also
not in the core. Plus the suspend/resume helper is also already there.

Needs a tiny bit of open-coding, but less midlayer beats that I think.

v2: Rebase onto ast (which gained a new user).
