a61cf3883c drm/i915/fbc: Introduce intel_fbc_set_false_color()
Pull the direct FBC register frobbing out from the debugfs code
into the fbc code. Also add a vfunc for this so we don't need
extra platforms checks.

fed98c16f1 drm/i915/display: Wait PSR2 get out of deep sleep to update pipe
Alderlake-P was getting 'max time under evasion' messages when PSR2
is enabled, this is due PIPE_SCANLINE/PIPEDSL returning 0 over a
period of time longer than VBLANK_EVASION_TIME_US.

For PSR1 we had the same issue so intel_psr_wait_for_idle() was
implemented to wait for PSR1 to get into idle state but nothing was
done for PSR2.

For PSR2 we can't only wait for idle state as PSR2 tends to keep
into sleep state(ready to send selective updates).
Waiting for any state below deep sleep proved to be effective in
avoiding the evasion messages and also not wasted a lot of time.

v2:
- dropping the additional wait_for loops, only the _wait_for_atomic()
is necessary
- waiting for states below EDP_PSR2_STATUS_STATE_DEEP_SLEEP

v3:
- dropping intel_wait_for_condition_atomic() function

Add a function for checking source MST support. Drop intel_dp->can_mst
and use intel_dp->mst_mgr.cbs to indicate the same. It's the single
point of truth without additional state variables. In code, "source
support" is also self-documenting as opposed to the vague "can mst".

a6922f4a01 drm/i915/xelpd: Add XE_LPD power wells
Aside from the hardware-managed PG0, XE_LPD has power wells 1-2 and
A-D.  These power wells should be enabled/disabled according to the
following dependency tree (enable top to bottom, disable bottom to top):

               PG0
                |
             --PG1--
            /       \

                 /   |   \
               PGB  PGC  PGD

PWR_WELL_CTL follows the general ICL/TGL design and places PG A-D in the
bits that would have been PG 6-9 under the old scheme.

PWR_WELL_CTL_{DDI,AUX}'s bit indexing for DDI's A-C and TC1 is the same
as TGL, but DDI-D is placed at index 7 (bits 14 & 15).

70bfb30743 drm/i915/display: Eliminate IS_GEN9_{BC,LP}
Now that we've eliminated INTEL_GEN(), IS_GEN_RANGE(), etc. from the
display code, we should also kill off our use of the IS_GEN9_* macros
too.  We'll do the conversion manually this time instead of using
Coccinelle since the most logical substitution can depend heavily on the
code context, and sometimes we can keep the code simpler if we make
additional adjustments such as swapping the order of if/else arms.

2b5a4562ed drm/i915/display: Simplify GLK display version tests
GLK has always been a bit of a special case since it reports INTEL_GEN()
as 9, but has version 10 display IP.  Now we can properly represent the
display version as 10 and simplify the display generation tests
throughout the display code.

Aside from manually adding the version to the glk_info structure, the
rest of this patch is generated with a Coccinelle semantic patch.  Note
that we also need to switch any code that matches gen10 today but *not*
GLK to be CNL-specific:

d0f1bfc615 drm/i915: Use pipes instead crtc indices in PLL state tracking
All the other places we have use pipes instead of crtc indices
when tracking resource usage. Life is easier when we do it
the same way always, so switch the dpll mgr to using pipes as
well. Looks like it was actually mixing these up in some cases
so it would not even have worked correctly except when the
device has a contiguous set of pipes starting from pipe A.
Granted, that is the typical case but supposedly it may not
always hold on modern hw.

And this moves and renames the i915_psr structure of drm_i915_private's to

ef79d62b5c drm/i915: Encapsulate dbuf state handling harder
In order to make the dbuf state computation less fragile
let's make it stand on its own feet by not requiring someone
to peek into a crystall ball ahead of time to figure out
which pipes need to be added to the state under which potential
future conditions. Instead we compute each piece of the state
as we go along, and if any fallout occurs that affects more than
the current set of pipes we add the affected pipes to the state
naturally.

That requires that we track a few extra thigns in the global
dbuf state: dbuf slices for each pipe, and the weight each
pipe has when distributing the same set of slice(s) between
multiple pipes. Easy enough.

We do need to follow a somewhat careful sequence of computations
though as there are several steps involved in cooking up the dbuf
state. Thoguh we could avoid some of that by computing more things
on demand instead of relying on earlier step of the algorithm to
have filled it out. I think the end result is still reasonable
as the entire sequence is pretty much consolidated into a single
function instead of being spread around all over.

The rough sequence is this:
1. calculate active_pipes
2. calculate dbuf slices for every pipe
3. calculate total enabled slices
4. calculate new dbuf weights for any crtc in the state
5. calculate new ddb entry for every pipe based on the sets of
   slices and weights, and add any affected crtc to the state
6. calculate new plane ddb entries for all crtcs in the state,
   and add any affected plane to the state so that we'll perform
   the requisite hw reprogramming

And as a nice bonus we get to throw dev_priv->wm.distrust_bios_wm
out the window.

v2: Keep crtc_state->wm.skl.ddb

829270e455 drm/i915/display: Record the plane update times for debugging
Since we try and estimate how long we require to update the registers to
perform a plane update, it is of vital importance that we measure the
distribution of plane updates to better guide our estimate. If we
underestimate how long it takes to perform the plane update, we may
slip into the next scanout frame causing a tear. If we overestimate, we
may unnecessarily delay the update to the next frame, causing visible
jitter.

Replace the warning that we exceed some arbitrary threshold for the
vblank update with a histogram for debugfs.

v2: Add a per-crtc debugfs entry so that the information is easier to
extract when testing individual CRTC, and so that it can be reset before
a test.

v3: Flip the graph on its side; creates space to label the time axis.

5bcc95ca38 drm/i915/dg1: Update DMC_DEBUG register
Update the DMC_DEBUG_DC5 register to its new location and do not try
reading the DC6 counter since DG1 doesn't support DC6.

v2: Use IS_DGFX() instead of IS_DG1(). Even if not having DC6 is not
directly related to DGFX, the register move to a new location is. So in
future, if there is one supporting DC6, it would just need to add the
other register rather than fixing the case of a wrong register being
read (Matt)

42f2562ca1 drm/dp: Pimp drm_dp_downstream_max_bpc()
Deal with more cases in drm_dp_downstream_max_bpc():
- DPCD 1.0 -> assume 8bpc for non-DP
- DPCD 1.1+ DP (or DP++ with DP sink) -> allow anything
- DPCD 1.1+ TMDS -> check the caps, assume 8bpc if the value is crap
- anything else -> assume 8bpc

v2: Use Returns: for kdoc (Lyude)

6e43e276b8 drm/i915: Initial implementation of PSR2 selective fetch
All GEN12 platforms supports PSR2 selective fetch but not all GEN12
platforms supports PSR2 hardware tracking(aka RKL).

This feature consists in software programming registers with the
damaged area of each plane this way hardware will only fetch from
memory those areas and sent the PSR2 selective update blocks to panel,
saving even more power.

But as initial step it is only enabling the full frame fetch at
every flip, the actual selective fetch part will come in a future
patch.

Also this is only handling the page flip side, it is still completely
missing frontbuffer modifications, that is why the
enable_psr2_sel_fetch parameter was added.

v3:
- calling intel_psr2_sel_fetch_update() during the atomic check phase
