drm: Split out drm_probe_helper.h

2019-01-24T12:20:42+00:00

Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.

To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.

v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.

v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.

This will also conflict with ongoing drmP.h cleanup by others I
expect.

v3: Rebase on top of atomic bochs.

v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
  other places (all suggested from Laurent adopted unchanged).
- sort alphabetically

v5: Actually try to sort them, and while at it, sort all the ones I
touch.

v6: Rebase onto i915 changes.

v7: Rebase once more.

drm/arcpgu: prepare for drmP.h removal from drm_modeset_helper.h

2019-01-24T12:06:54+00:00

The use of drmP.h is discouraged and removal of it from
drm_modeset_helper.h caused arcgpu to fail to build.

This patch introduce the necessary fixes to prepare for the
drmP.h removal from drm_modeset_helper.h.
List of include files sorted alphabetically.

Build tested on arm x86 and arm allmodconfig.

drm/arc: do not rely on drmP.h from drm_gem_cma_helper.h

2019-01-09T21:48:51+00:00

drmP.h was the only header file in the past and a lot
of files rely on that drmP.h defines everything.
The goal is to one day to delete drmP.h and
as a step towards this it will no longer be included in the
headers files in include/drm/

To prepare arc/ for this add dependencies that
othwewise was pulled in by drmP.h from drm_gem_cma_helper.h

drm/arc: Use drm_fbdev_generic_setup()

2018-11-01T14:23:21+00:00

The CMA helper is already using the drm_fb_helper_generic_probe part of
the generic fbdev emulation. This patch makes full use of the generic
fbdev emulation by using its drm_client callbacks. This means that
drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are
now handled by the emulation code. Additionally fbdev unregister happens
automatically on drm_dev_unregister().

The drm_fbdev_generic_setup() call is put after drm_dev_register() in the
driver. This is done to highlight the fact that fbdev emulation is an
internal client that makes use of the driver, it is not part of the
driver as such. If fbdev setup fails, an error is printed, but the driver
succeeds probing.

drm/arcpgu: Use drm_atomic_helper_shutdown

2018-10-05T16:04:09+00:00

drm_plane_helper_disable is a non-atomic drivers only function, and
will blow up (since no one passes the locking context it needs).

Atomic drivers which want to quiescent their hw on unload should
use drm_atomic_helper_shutdown() instead.

drm: add missing ctx argument to plane transitional helpers

2018-07-03T07:30:19+00:00

In commits:
34a2ab5e0689 ("drm: Add acquire ctx parameter to ->update_plane")
1931529448bc ("drm: Add acquire ctx parameter to ->plane_disable")

a pointer to a drm_modeset_acquire_ctx structure was added as an
argument to the method prototypes.  The transitional helpers are
supposed to be directly plugged in as implementations of these
methods, but doing so generates a warning.  Add the missing
argument.

A number of buggy users were added for drm_plane_helper_disable()
which need to be fixed up for this change, which we do by passing
a NULL ctx argument.
