drm/virtio: Use the drm_driver.dumb_destroy default

2017-08-16T18:20:00+00:00

virtio_gpu_mode_dumb_destroy() is the same as drm_gem_dumb_destroy()
which is the drm_driver.dumb_destroy default, so no need to set it.

Make these structures const as they are only passed to the function
drm_fb_helper_prepare and the corresponding argument is of type const.

drm: Nuke drm_atomic_helper_connector_dpms

2017-08-08T12:48:48+00:00

It's dead code, the core handles all this directly now.

The only special case is nouveau and tda988x which used one function
for both legacy modeset code and -nv50 atomic world instead of 2
vtables. But amounts to exactly the same.

v2: Rebase over the panel/brideg refactorings in stm/ltdc.

drm: Plumb modifiers through plane init

2017-08-01T16:50:06+00:00

This is the plumbing for supporting fb modifiers on planes. Modifiers
have already been introduced to some extent, but this series will extend
this to allow querying modifiers per plane. Based on this, the client to
enable optimal modifications for framebuffers.

This patch simply allows the DRM drivers to initialize their list of
supported modifiers upon initializing the plane.

v2: A minor addition from Daniel

v3:
* Updated commit message
* s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu)
* Remove some excess newlines (Liviu)
* Update comment for > 64 modifiers (Liviu)

v4: Minor comment adjustments (Liviu)

v5: Some new platforms added due to rebase

v6: Add some missed plane inits (or maybe they're new - who knows at
this point) (Daniel)

drm/: Drop fbdev info flags

2017-07-26T11:22:40+00:00

- FBINFO_CAN_FORCE_OUTPUT has been a lie ever since we nerfed&removed
  the entire panic handling code in our fbdev emulation. We might
  restore kms panic output, but not through the bazillion of legacy
  code layers called fbdev/fbcon, there's just no way to make that
  work safely.

- With the module check change FBINFO_DEFAULT is always 0, so can be
  removed too.

That removes another change to cargo-cult stuff in kms drivers, yay!

drm: Convert atomic drivers from CRTC .disable() to .atomic_disable()

2017-06-30T12:53:15+00:00

The CRTC .disable() helper operation is deprecated for atomic drivers,
the new .atomic_disable() helper operation being preferred. Convert all
atomic drivers to .atomic_disable() to avoid cargo-cult use of
.disable() in new drivers.

drm: Add old state pointer to CRTC .enable() helper function

2017-06-30T12:53:14+00:00

The old state is useful for drivers that need to perform operations at
enable time that depend on the transition between the old and new
states.

While at it, rename the operation to .atomic_enable() to be consistent
with .atomic_disable(), as the .enable() operation is used by atomic
helpers only.

drm: Remove drm_device->virtdev

2017-05-29T18:57:25+00:00

This is a leftover from the drm_bus days, where we've had a
bus-specific device type for every bus type in drm_device. Except for
pci (which we can't remove because dri1 drivers) this is all gone. And
the virt driver also doesn't really need it, dev_to_virtio works
perfectly fine.
