Daniel Vetter fcd70cd36b drm: Split out drm_probe_helper.h
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.

Daniel Vetter a2b50babc7 drm/sti: Use drm_atomic_helper_shutdown
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.

The sti cleanup code seems supremely confused:
- In the load error path it calls drm_mode_config_cleanup before it
  stops various kms services like poll worker or fbdev emulation.
  That's going to oops.
- The actual unload code doesn't even bother with the cleanup and just
  leaks.

Try to fix this while at it.

Noralf Trønnes 0f26e5ce3e drm/sti: Use drm_fbdev_generic_setup()
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().

If drm_fbdev_generic_setup() fails, an error is printed by the function.

drm_fbdev_generic_setup() handles mode_config.num_connector being zero.
In that case it retries fbdev setup on the next .output_poll_changed.

Instead of re-implementing the drm_atomic_helper_check() locally with just

Note: the drm_atomic_helper_check() now includes

if (state->legacy_cursor_update)
	state->async_update = !drm_atomic_helper_async_check(drm, state);

which was added after the driver moved away from using it

Noralf Trønnes 53889c92fd drm/sti: Use drm_fb_cma_fbdev_init/fini()
Use drm_fb_cma_fbdev_init() and drm_fb_cma_fbdev_fini() which relies on
the fact that drm_device holds a pointer to the drm_fb_helper structure.
This means that the driver doesn't have to keep track of that.
Also use the drm_fb_helper functions directly.

Daniel Vetter d55f7e5d54 drm: Create DEFINE_DRM_GEM_CMA_FOPS and roll it out to drivers
Less code ftw.

This converts all drivers except the tinydrm helper module. That one
needs more work, since it gets the THIS_MODULE reference from
tinydrm.ko instead of the actual driver module like it should.
Probably needs a similar trick like I used here with generating the
entire struct with a macro.

Gabriel Krisman Bertazi e4563f6ba7 drm: Rely on mode_config data for fb_helper initialization
Instead of receiving the num_crts as a parameter, we can read it
directly from the mode_config structure.  I audited the drivers that
invoke this helper and I believe all of them initialize the mode_config
struct accordingly, prior to calling the fb_helper.

I used the following coccinelle hack to make this transformation, except
for the function headers and comment updates.  The first and second
rules are split because I couldn't find a way to remove the unused
temporary variables at the same time I removed the parameter.

Ville Syrjälä 38d868e41c drm: Don't force all planes to be added to the state due to zpos
We don't want all planes to be added to the state whenever a
plane with fixed zpos gets enabled/disabled. This is true
especially for eg. cursor planes on i915, as we want cursor
updates to go through w/o throttling. Same holds for drivers
that don't support zpos at all (i915 actually falls into this
category right now since we've not yet added zpos support).

Allow drivers more freedom by letting them deal with zpos
themselves instead of doing it in drm_atomic_helper_check_planes()
unconditionally. Let's just inline the required calls into all
the driver that currently depend on this.

v2: Inline the stuff into the drivers instead of adding another
    helper, document things better (Daniel)

Chris Wilson 0853695c3b drm: Add reference counting to drm_atomic_state
drm_atomic_state has a complicated single owner model that tracks the
single reference from allocation through to destruction on another
thread - or perhaps on a local error path. We can simplify this tracking
by using reference counting (at a cost of a few more atomics). This is
even more beneficial when the lifetime of the state becomes more
convoluted than being passed to a single worker thread for the commit.

Liu Ying 2b58e98d42 drm/atomic-helper: Add NO_DISABLE_AFTER_MODESET flag support for plane commit
Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter
of the helper drm_atomic_helper_commit_planes() if the relevant display
controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes
when the CRTC is disabled. The helper would skip the ->atomic_disable
call for a plane if the CRTC of the old plane state needs a modesetting
operation. Of course, the drivers need to disable the planes in their CRTC
disable callbacks since no one else would do that.

Shawn Guo e1f96ef46c drm: drop DRIVER_HAVE_IRQ flag for some drivers
Since commit 4984979b9b ("drm/irq: simplify irq checks in
drm_wait_vblank"), the drm driver feature flag DRIVER_HAVE_IRQ is only
required for drivers that have an IRQ handler managed by the DRM core.
Some drivers, armada, etnaviv, kirin and sti, set this flag without
.irq_handler setup in drm_driver.  These drivers manage IRQ handler
by themselves and the flag DRIVER_HAVE_IRQ makes no sense there.

Drop the flag for these drivers to avoid confusion.

Maxime Ripard 4314e19ef4 drm/fb_cma_helper: Remove implicit call to disable_unused_functions
The drm_fbdev_cma_init function always calls the
drm_helper_disable_unused_functions. Since it's part of the usual probe
process, all the drivers using that helper will end up having their encoder
and CRTC disable functions called at probe if their device has not been
reported as enabled.

This could be fixed by reading out from the registers the current state of
the device if it is enabled, but even that will not handle the case where
the device is actually disabled.

Moreover, the drivers using the atomic modesetting expect that their enable
and disable callback to be called when the device is already enabled or
disabled (respectively).

We can however fix this issue by moving the call to
drm_helper_disable_unused_functions out of drm_fbdev_cma_init and make the
drivers needing it (all the drivers calling drm_fbdev_cma_init and not
using the atomic modesetting) explicitly call it.
