From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We want to get rid of plane->fb/crtc on atomic drivers. Stop
looking at them.

v2: Catch the plane->crtc case too

[PATCH 10/13] drm/atmel-hlcdc: Stop using plane->fb

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We want to get rid of plane->fb on atomic drivers. Stop looking at it.

Daniel pointed out that the drm_framebuffer_put() in the plane cleanup
indicates that the driver doesn't shut things down cleanly. To do
that we should be able to just call drm_atomic_helper_shutdown(). Not
really sure the current cleanup sequence is actually sane, but whatever.

v2: Replace the drm_framebuffer_put() with
    drm_atomic_helper_shutdown() (Daniel)

[PATCH 11/13] drm/omapdrm: Nuke omap_framebuffer_get_next_connector()

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

omap_framebuffer_get_next_connector() uses plane->fb which we want to
deprecate for atomic drivers. As omap_framebuffer_get_next_connector()
is unused just nuke the entire function.

[PATCH 12/13] drm: Stop updating plane->crtc/fb/old_fb on atomic drivers

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Stop playing around with plane->crtc/fb/old_fb with atomic
drivers. Make life a lot simpler when we don't have to do the
magic old_fb vs. fb dance around plane updates. That way we
can't risk plane->fb getting out of sync with plane->state->fb
and we're less likely to leak any refcounts as well.

fwiw, here's how I review these:

First load a quickfix list using the following grep line:

Ggrep '\(plane\|primary\|cursor\)\S*\(fb\|crtc\)' -- drivers/gpu/drm/

But that includes the plenty of hits that do use state structs. So then I
filter for stuff without a preceeding state using vim's regexes:

\(plane\|primary\|cursor\)\(\S*state\S*\)\@!\S*\(->\|\.\)\(fb\|crtc\)

I'm feeling really bad about all this :-)

Cheers, Daniel

There's a bunch more hits I have:

- 2x a coment with "Both crtc and plane->crtc" in intel_atomic_plane.c.
  Probably best to just nuke those.

- One comment in intel_crtc_active, just needs to be switched to
  crtc->primary->state->fb to match the code.

It looks like you caught all the functional bits at least.

With the above fixed, this is.

More bad news, I found more places:

- arcpgu in arc_pgu_crtc_atomic_disable(), no idea what exactly that one
  tries to achieve.

- vmwgfx, especially vmwgfx_set_config_internal(). vmwgfx folks still owe
  me a conversion of their driver to the fbdev helpers :-/

But slowly getting there I think.

Cheers, Daniel

I think this can go in before the previous patch.

[PATCH v2 05/13] drm/i915: Stop updating plane->fb/crtc

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We want to get rid of plane->fb/crtc on atomic drivers. Stop setting
them.

v2: Fix up the comment in intel_crtc_active() and
    nuke the rest of the stale comments (Daniel)

I tried to remove it just a week ago, but Sebastian said that it's used
by a unmerged series about DSI command mode displays, so I dropped the
patch.

In the unmerged series, it's used by omap_framebuffer_dirty() ([PATCHv3
3/8] drm/omap: add support for manually updated displays). So we have a
framebuffer, and we want to know which crtcs need to be flushed.

You can't do that in atomic drivers.

You need to take appropriate locks and do the full ->state->fb deref.
Also, there's a gazillion of copies for generic framebuffer_dirty
implementations floating around, pleas try to coordinate with those.

Ok. In that case we need to refresh the manual update series to do
things differently. For this patch:
