Abstract the fb pin/unpin stuff under a new 'fb_pin' parent
interface. The interface is fairly low level so that the i915/xe
side doesn't need access to any display specific data structures.
There are perhaps some needless extra layers on the i915/xe side
afterwards, but we can clean those out later. There are also some
rough corners left in the initial fb code, but I'll be following
up with a separate series to fix/clean up that whole thing.
Ville Syrjälä (16):
drm/i915: Introduce intel_parent_fb_pin_get_map()
drm/i915: Move intel_fb_pin_params to the parent interface
drm/i915: Move the i915_dpt_offset()==0 assert
drm/i915: Reorganize intel_plane_pin_fb() a bit
drm/i915: Introduce i915_fb_pin_dpt_(un)pin()
drm/i915: Introduce i915_fb_pin_ggtt_(un)pin()
drm/xe: Move the FORCE_WC assert into __xe_pin_fb_vma()
drm/xe: Kill the fbdev vma reuse hack
drm/xe: Reorganize intel_plane_pin_fb() a bit
drm/xe: Introduce xe_fb_pin_dpt_(un)pin()
drm/xe: Introduce xe_fb_pin_ggtt_(un)pin()
drm/xe: Restructure reuse_vma()
drm/i915: Introduce the main fb_pin parent interface
drm/i915/fbdev: Use intel_parent_fb_pin_ggtt_(un)pin()
drm/xe: Use xe_fb_pin_ggtt_pin() for the initial FB pin
drm/i915: Consolidate the intel_plane_(un)pin_fb() implementations

Introduce the "fb_pin" parent interface, as the first trivial step
move the *_get_map() stuff there.
The whole "fb_pin" as an interface might not really make sense,
and perhaps this (and other stuff) should just be collected into
some kind of "bo" interface. But let's go with "fb_pin" for now
to match where things are implemented, and possibly restructure
it later.

strut intel_fb_pin_params will be an important part of the fb_pin
interface, so move the definition to the parent interface file.
Or maybe we should have a separate header for this kind of stuff
since the users of the parent interface will need the struct
definition but not the parent interface vfunc struct definitions?

Move the i915_dpt_offset() check into the lower level
intel_fb_pin_to_dpt() function. Clears out some of the unnecessary
junk from the higher level code, making it easier to introduce
the new fb_pin parent interface.

Move most of the plane state stuff out from the inner parts
of intel_plane_pin_fb(). The plan is to take those inner parts and
abstract them into the new fb_pin parent interface, and we don't
want any plane_state stuff there.

No need to bother the higher level pinning code with the
FORCE_WC assert. Move it into the lower level function.

This fbdev vma reuse hacks is a massive layering violation. It
really does not belong in the fb pinning code. And it's in the
way of properly abstracting this stuff, so kill it.

Move most of the plane state stuff out from the inner parts
of intel_plane_pin_fb(). The plan is to take those inner parts and
abstract them into the new fb_pin parent interface, and we don't
want any plane_state stuff there.

Restructure reuse_vma() into a form that doesn't need the plane
state structs, and rename the result to xe_fb_pin_reuse_vma().
This will become the new fb_pin parent interface.

Introduce the main part of the new fb_pin parent interface:
- intel_parent_fb_pin_ggtt_(un)pin()
- intel_parent_fb_pin_dpt_(un)pin()
- intel_parent_fb_pin_reuse_vma()

To: intel-gfx; +Cc: intel-xe
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
Replace the intel_fb_pin_to_ggtt() and intel_fb_unpin_vma() with the
new abstract parent interface (intel_parent_fb_pin_ggtt_(un)pin()).
xe no longer needs intel_fb_unpin_vma(), and in i915 it now
becomes and internal function to i915_fb_pin.

Use xe_fb_pin_ggtt_pin() instead of intel_fb_pin_to_ggtt() for
the initial FB pin. We want to get rid of intel_fb_pin_to_ggtt()
and just use the new fb_pin parent interface.
This still isn't quite the final solution since we bypass the
actual parent interface and call the implementation directly.
But sorting that out will require more cleanup to the initial
FB code.

Currently i915 and each implement their own versions of
intel_plane_(un)pin(). Now that we have the fb_pin parent
interface we can consolidate this to a single implementation.
The result is a mixture of the i915 and xe implementations.
The reuse_vma() hack comes from xe (and i915 doesn't implement
that part of the parent interface, and the pin_params are
taken from i915 since the platforms supported by i915 need
more things.

commit 5b6d72673d7f106cfb3c6d560569d252ad5e900a
Author: Ville Syrjälä <ville.syrjala@linux.intel.com>

drm/i915: Consolidate the intel_plane_(un)pin_fb() implementations
Currently i915 and each implement their own versions of
intel_plane_(un)pin(). Now that we have the fb_pin parent
interface we can consolidate this to a single implementation.
The result is a mixture of the i915 and xe implementations.
The reuse_vma() hack comes from xe (and i915 doesn't implement
that part of the parent interface, and the pin_params are
taken from i915 since the platforms supported by i915 need
more things.

Yeah, another hard one. I've tried to keep the interface definition
clear of other type definitions, and in particular to use types that are
readily available in generic drm headers. Or opaque pointers.
I think let's see how bad it gets. We're bound to need a few structs
specific to this interface, like struct intel_fb_pin_params. If it's
just a few structs, and they don't need to include the world for their
definition, let's just keep them here. But if it starts to look like
there'll be plenty, and they need a bunch of dependencies, let's split
them out. It's not a big deal to do that later.

However xe had something different here.
Basically fb->min_alignment is initialized to intel_fb_min_alignment(),
which does call plane->min_alignment() for all planes, and works it out
from there.
Could or should we have switched xe to use fb->min_alignment here as an
intermediate step? It kind of sticks out as a change in this patch.
