[Intel-gfx] [RFC PATCH 0/8] drm/i915/display: refactor plane config + pin out

[Intel-gfx] [RFC PATCH 0/8] drm/i915/display: refactor plane config + pin out

[Dave Airlie]

This is another series in the refactor intel_display.c into more manageable
places.

This moves the initial plane config and all the fb pin/unpin code out.

It also refactors both a little to make the interfaces cleaner.

Dave.

[Intel-gfx] [PATCH 1/8] drm/i915/display: move plane prepare/cleanup to intel_atomic_plane.c

[Dave Airlie]

From: Dave Airlie <airlied@redhat.com>

Start to refactor more stuff out of intel_display.c. These fit
better in this file.

This moves the rps boosting code as well as this is the only user of it.

[Intel-gfx] [PATCH 2/8] drm/i915/display: move intel_plane_uses_fence to inline.

[Dave Airlie]

From: Dave Airlie <airlied@redhat.com>

Make future refactoring simpler, but also this function is pretty
trivial.

In general, I'm pretty much opposed to adding any new inline functions
without a clear performance rationale. I've been gradually moving such
inlines out of headers instead.

They make it harder to abstract stuff by requiring visibility to all the
guts they're accessing. I'm hoping to remove #include "i915_drv.h" from
this header too, reducing the header interdependencies and the
"everything needs everything" model.

BR,
Jani.

[Intel-gfx] [PATCH 3/8] drm/i915/display: refactor out initial plane config for crtcs

[Dave Airlie]

From: Dave Airlie <airlied@redhat.com>

This just pulls this out into a function so it can be moved to
another file easier.

[Intel-gfx] [PATCH 5/8] drm/i915/display: move pin/unpin fb/plane code to a new file.

[Dave Airlie]

From: Dave Airlie <airlied@redhat.com>

This just moves this code out of the i915_display.c into a new
standalone file.

I had a few nitpicks I commented on. Overall this looks good to me, but
I'd like Ville's input on the code movement at the high level, are the
split and files sane etc. I can do the detailed review after that.

Some of it feels a bit ad-hoc, but I don't really have a better
idea for splitting some of these right now. So might as well go
with this I guess. cscope will find the stuff for me in the end,
at least after I remember to have it reindex.

My main goal was separation of things that interface with gem into
separate files for now.

I'd like to formalise that interface a bit more if we can, it might
not bear fruit but I think it would be independently useful cleanup
anyways.

[Intel-gfx] [RFC PATCH 0/8] drm/i915/display: refactor plane config + pin out (v2)

[Dave Airlie]

This is another series in the refactor intel_display.c into more manageable
places.

This moves the initial plane config and all the fb pin/unpin code out.

It also refactors both a little to make the interfaces cleaner.

v2: just address the minor comments from Jani.

Jani, I think Ville doesn't mind the resulting layout.

Dave.

[Intel-gfx] [PATCH 4/8] drm/i915/display: refactor initial plane config to a separate file

[Dave Airlie]

From: Dave Airlie <airlied@redhat.com>

This moves this functionality out of intel_display.c to separate
self-contained file.
