Merge drm/drm-next into drm-misc-next

2019-10-03T14:38:50+00:00

We haven't done any backmerge for a while due to the merge window, and it
starts to become an issue for komeda. Let's bring 5.4-rc1 in.

drm/atomic: Rename crtc_state->pageflip_flags to async_flip

2019-09-18T16:43:36+00:00

It's the only flag anyone actually cares about. Plus if we're unlucky,
the atomic ioctl might need a different flag for async flips. So
better to abstract this away from the uapi a bit.

drm: Stop including drm_bridge.h from drm_crtc.h

2019-08-28T20:11:03+00:00

We are about to add a drm_bridge_state that inherits from
drm_private_state which is defined in drm_atomic.h. Problem is,
drm_atomic.h includes drm_crtc.h which in turn includes drm_bridge.h,
leading to "drm_private_state has incomplete type" error.

Let's force all users of the drm_bridge API to explicitly include
drm_bridge.h.

drm/crc-debugfs: Add notes about CRC<->commit interactions

2019-08-06T17:27:53+00:00

CRC generation can be impacted by commits coming from userspace, and
enabling CRC generation may itself trigger a commit. Add notes about
this to the kerneldoc.

Changes since v1:
 - Clarified that anything that would disable CRCs counts as a full
   modeset, and so userspace needs to reconfigure after full modesets

Changes since v2:
 - Add these notes
 - Rebase onto drm-misc-next (trivial conflict in comment)

drm: Add helpers to kick off self refresh mode in drivers

2019-06-13T18:31:10+00:00

This patch adds a new drm helper library to help drivers implement
self refresh. Drivers choosing to use it will register crtcs and
will receive callbacks when it's time to enter or exit self refresh
mode.

In its current form, it has a timer which will trigger after a
driver-specified amount of inactivity. When the timer triggers, the
helpers will submit a new atomic commit to shut the refreshing pipe
off. On the next atomic commit, the drm core will revert the self
refresh state and bring everything back up to be actively driven.

From the driver's perspective, this works like a regular disable/enable
cycle. The driver need only check the 'self_refresh_active' state in
crtc_state. It should initiate self refresh mode on the panel and enter
an off or low-power state.

Changes in v2:
- s/psr/self_refresh/ (Daniel)
- integrated the psr exit into the commit that wakes it up (Jose/Daniel)
- made the psr state per-crtc (Jose/Daniel)
Changes in v3:
- Remove the self_refresh_(active|changed) from connector state (Daniel)
- Simplify loop in drm_self_refresh_helper_alter_state (Daniel)
- Improve self_refresh_aware comment (Daniel)
- s/self_refresh_state/self_refresh_data/ (Daniel)
Changes in v4:
- Move docbook location below panel (Daniel)
- Improve docbook with references and more detailed explanation (Daniel)
- Instead of register/unregister, use init/cleanup (Daniel)
Changes in v5:
- Resolved conflict in drm_atomic_helper.c #include block
- Resolved conflict in rst with HDCP helper docs
Changes in v6:
- Fix include ordering, clean up forward declarations (Sam)

drm: drm_crtc.h self-contained

2019-06-10T20:30:24+00:00

While removing drmP.h from drm/radeon a few files ended
up including drm_crtc.h as the first file.
This failed build due to a missing dependency in drm_crtc.h.

Add the missing include file.

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).
