[Intel-gfx] [PATCH 01/17] drm/i915/fbc: Exract snb_fbc_program_fence()

[Ville Syrjala]

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

We have two identical copies of the snb+ system agent
CPU fence programming code. Extract into a helper.

Also there's no real point in insisting that we
program 0 into DPFC_CPU_FENCE_OFFSET when the fence is
disabled. So just always stick the computed Y offset there
whether or not the fence is actually used or not.

[Intel-gfx] [PATCH 03/17] drm/i915/fbc: Just use params->fence_y_offset always

[Ville Syrjala]

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

No need to tiptoe around programming DPFC_FENCE_YOFF with
params->fence_y_offset vs. 0. If the fence is not enabled
it doesn't even matter what we program here.

[Intel-gfx] [PATCH 05/17] drm/i915/fbc: Extract helpers to compute FBC control register values

[Ville Syrjala]

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

Declutter the *_fbc_activate() functions by pulling all the
control register value computations into helpers.

I left the enable bit in *_fbc_activate() in the hopes of maybe
using the helpers in the *_fbc_deactivate() paths as well instead
of the current rmw approach. That won't be possible at least
quite yet since we clobber the fbc->params before deactivating
FBC so we could end up changing some of the values live, which
given FBC's lack of/poor double buffering would likely not go
so well.

[Intel-gfx] [PATCH 07/17] drm/i915/fbc: Introduce .nuke() vfunc

[Ville Syrjala]

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

Eliminate yet another if-ladder by adding .nuke() vfunc.

We also rename all *_recompress() stuff to *_nuke() since
that's the terminology the spec uses. Also "recompress"
is a bit confusing by perhaps implying that this triggers
an immediate recompression. Depending on the hardware that
may definitely not be the case, and in general we don't
specifically know when the hardware decides to compress.
So all we do is "nuke" the current compressed framebuffer
and leave it up to the hardware to recompress later if it
so chooses.

[Intel-gfx] [PATCH 08/17] drm/i915/fbc: s/gen7/ivb/

[Ville Syrjala]

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

"gen7" in display code is not really sensible. We shall call
these things "ivb".

[Ville Syrjala]

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

Just use a same mask for ivb/hsw as for bdw+. The extra bit
in the bdw mask is mbz on ivb/hsw anyway so this is just
pointless complexity.

[Intel-gfx] [PATCH 12/17] drm/i915/fbc: Clean up all register defines

[Ville Syrjala]

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

The FBC register defines are a mess:
- namespace changes between DPFC_, FBC_, and some platform
  specific prefix at a whim
- ilk+ reuses most g4x bits but still has some separate bit
  defines elsewhere
- it's not clear from the defines that the bit defines are
  shared

So let's clean it up:
- both g4x and ilk register share the same defines now
- only defines which conflict have a _PLATFORM suffix, everyone
  else just gets comments to indicate which platforms do what
- namespace is consistent DPFC_ now
- SNB system agent fence registers also get a consistent namespace
- REG_BIT() & co. for everything

[Intel-gfx] [PATCH 13/17] drm/i915/fbc: Finish polishing FBC1 registers

[Ville Syrjala]

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

Switch all the FBC1 registers over to REG_BTT()/etc.
And while at it add a few more registers/bits that
escaped the net previously.

[Intel-gfx] [PATCH 14/17] drm/i915: Relocate FBC_LLC_READ_CTRL

[Ville Syrjala]

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

In the case of FBC_LLC_READ_CTRL the "FBC" stands for
frame buffer _caching_, not frame buffer compression.
Move the register definition out from the middle of the
frame buffer compression register definitions. Let's
just stick it somewhere with similar looking register
offsets.

And while at it switch it over to REG_BIT().

[Intel-gfx] [PATCH 16/17] drm/i915/fbc: Start passing around intel_fbc

[Ville Syrjala]

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

In preparation for multiple FBC instances start passing around
intel_fbc pointers rather than i915 pointers. And once there are
multiple of these we can't rely on container_of() to get back to
the i915, so we toss in a fbc->i915 pointer already.

[Intel-gfx] [PATCH 17/17] drm/1915/fbc: Replace plane->has_fbc with a pointer to the fbc instance

[Ville Syrjala]

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

With multiple fbc instances we need to find the right one for each
plane. Rather than going looking for the right instance every time
let's just replace the has_fbc boolean with a pointer that gets us
there straight away.
