daed3e4439 drm/i915/perf: implement active wait for noa configurations
NOA configuration take some amount of time to apply. That amount of
time depends on the size of the GT. There is no documented time for
this. For example, past experimentations with powergating
configuration changes seem to indicate a 60~70us delay. We go with
500us as default for now which should be over the required amount of
time (according to HW architects).

7d423af9bf drm/i915: Implement a better i945gm vblank irq vs. C-states workaround
The current "disable C3+" workaround for the delayed vblank
irqs on i945gm no longer works. I'm not sure what changed, but
now I need to also disable C2. I also got my hands on a i915gm
machine that suffers from the same issue.

After some furious poking of registers I managed to find a
better workaround: The "Do not Turn off Core Render Clock in C
states" bit. With that I no longer have to disable any C-states,
and as a nice bonus the power cost is only ~1/4 of the
"disable C3+" method (which mind you doesn't even work anymore,
and so would have an even higher power cost if we made it work
by also disabling C2).

So let's throw out all the cpuidle/qos crap and just toggle
the magic bit as needed. And we extend the workaround to cover
i915gm as well.

84af764918 drm/i915/color: Extract icl_read_luts()
For icl+, have hw read out to create hw blob of gamma
lut values. icl+ platforms supports multi segmented gamma
mode by default, add hw lut creation for this mode.

This will be used to validate gamma programming using dsb
(display state buffer) which is a tgl specific feature.

Major change done-removal of readouts of coarse and fine segments
because PAL_PREC_DATA register isn't giving propoer values.
State checker limited only to "fine segment"

v2: -readout code for multisegmented gamma has to come
     up with some intermediate entries that aren't preserved
     in hardware (Jani N)
    -linear interpolation (Ville)
    -moved common code to check gamma_enable to specific funcs,
     since icl doesn't support that
v3: -use u16 instead of __u16 [Jani N]
    -used single lut [Jani N]
    -improved and more readable for loops [Jani N]
    -read values directly to actual locations and then fill gaps [Jani N]
    -moved cleaning to patch 1 [Jani N]
    -renamed icl_read_lut_multi_seg() to icl_read_lut_multi_segment to
     make it similar to icl_load_luts()
    -renamed icl_compute_interpolated_gamma_blob() to
     icl_compute_interpolated_gamma_lut_values() more sensible, I guess

some duplicated resources/paths. Although DSS behave similarly to 2
subslices, instead of splitting this and presenting userspace with bits
not directly representative of hardware resources, present userspace
with a subslice_mask made up of DSS bits instead.

d1844606fd drm/i915: Add PIPECONF YCbCr 4:4:4 programming for ILK-IVB
On ILK-IVB the pipe colorspace is configured via PIPECONF
(as opposed to PIPEMISC in BDW+). Let's configure+readout
that stuff correctly.

Enabling YCbCr 4:4:4 output will now be a simple matter of
setting crtc_state->output_format appropriately in the encoder
.compute_config(). However, when we do that we must be
aware of the fact that YCbCr DP output doesn't seem to work
on ILK (resulting image is totally garbled), but on SNB+
it works fine. However HDMI YCbCr output does work correctly
even on ILK.

af28cc4c28 drm/i915: Set up ILK/SNB csc unit properly for YCbCr output
Prepare the pipe csc for YCbCr output on ilk/snb. The main difference
to IVB+ is the lack of explicit post offsets, and instead we must
configure the CSC info RGB->YUV mode (which takes care of offsetting
Cb/Cr properly) and enable the "black screen offset" bit to add the
required offset to Y.

And while at it throw some comments around the bit defines to
document which platforms have which bits.

4444df6e20 drm/i915/tgl: move DP_TP_* to transcoder
Gen 12 onwards moves the DP_TP_* registers to be transcoder-based rather
than port-based. This adds the new register addresses and changes all
the callers to use the register saved in intel_dp->regs.*. This is
filled out when preparing to enable the port so we take into account if
we should use the transcoder or the port.

v2: reimplement by stashing the registers we want to access under
intel_dp->reg. Now they are initialized when enabling the port.
Ville suggested to store the transcoder to be used exclusively
by TGL+. After implementing I thought just storing the register directly
made it cleaner.

8241cfbe67 drm/i915/tgl: Access the right register when handling PSR interruptions

registers moved to each transcoder offset. The bits for the registers
are defined without an offset per transcoder as right now we have one
register per transcoder. So add a fake "trans_shift" when calculating
the bits offsets: it will be 0 for gen12+ and psr.transcoder otherwise.

2f3b87124b drm/i915/psr: Only handle interruptions of the transcoder in use
It was enabling and checking PSR interruptions in every transcoder
while it should keep the interruptions on the non-used transcoders
masked.

While doing this it gives us trouble on Tiger Lake if we are
reading/writing to registers of disabled transcoders since from gen12
onwards the registers are relative to the transcoder. Instead of forcing
them ON to access those registers, just avoid the accesses as they are
not needed.

v2 (Lucas):
  - Explain why we can't keep accessing all transcoders
  - Remove TODO about extending the irq handling to multiple instances:
    when/if implementing multiple instances it's pretty clear by the
    singleton psr that it needs to be extended
  - Fix intel_psr_debug_set() calling psr_irq_control() with
    psr.transcoder not set yet (from Imre). Now we only set the debug
    register right away if psr is already enabled. Otherwise we just
    record the value to be set when enabling the source.
  - Do not depend on the value of TRANSCODER_A. Just be relative to it
    (from Imre)
  - handle psr error last so we don't schedule the work before handling
    the other flags

v3:
  - Adding a warning about setting reserverd bits on EDP_PSR_IMR

385ba629aa drm/i915: Allow /2 CD2X divider on gen11+
The bspec has just recently been updated with new cdclk values that
require the use of a /2 CD2X divider rather than a /1 divider.  Once we
add the divider selection logic to ICL+ cdclk programming, we have
pretty much the same logic we were already using on CNL, so it's simpler
to drop icl_set_cdclk() completely and reuse cnl_set_cdclk() on gen11+
platforms as well.

v2:
 - Using ICL_CDCLK_CD2X_PIPE_NONE + BXT_CDCLK_CD2X_PIPE(pipe) for TGL is
   correct, but looks really confusing.  Add some TGL_ macros that alias
   these to avoid confusion.  (Ville)
 - Use DIV_ROUND_CLOSEST rather than / when applying the divider. (Ville)

4ab4fa1032 drm/i915/psr: Make PSR registers relative to transcoders
PSR registers are a mess, some have the full address while others just
have the additional offset from psr_mmio_base.

For BDW+ psr_mmio_base is nothing more than TRANSCODER_EDP_OFFSET +
0x800 and using it makes more difficult for people with an PSR
register address or PSR register name from from BSpec as i915 also
don't match the BSpec names.
For HSW psr_mmio_base is _DDI_BUF_CTL_A + 0x800 and PSR registers are
only available in DDIA.

Other reason to make relative to transcoder is that since BDW every
transcoder have PSR registers, so in theory it should be possible to
have PSR enabled in a non-eDP transcoder.

So for BDW+ we can use _TRANS2() to get the register offset of any
PSR register in any transcoder while for HSW we have _HSW_PSR_ADJ
that will calculate the register offset for the single PSR instance,
noting that we are already guarded about trying to enable PSR in other
port than DDIA on HSW by the 'if (dig_port->base.port != PORT_A)' in
intel_psr_compute_config(), this check should only be valid for HSW
and will be changed in future.
PSR2 registers and PSR_EVENT was added after Haswell so that is why
_PSR_ADJ() is not used in some macros.

The only registers that can not be relative to transcoder are
PSR_IMR and PSR_IIR that are not relative to anything, so keeping it
hardcoded. That changed for TGL but it will be handled in another
patch.

Also removing BDW_EDP_PSR_BASE from GVT because it is not used as it
is the only PSR register that GVT have.

v5:
- Macros changed to be more explicit about HSW (Dhinakaran)
- Squashed with the patch that added the tran parameter to the
macros (Dhinakaran)

v6:
- Checking for interruption errors after module reload in the
transcoder that will be used (Dhinakaran)
- Using lowercase to the registers offsets

v7:
- Removing IS_HASWELL() from registers macros(Jani)

b41e63d881 drm/i915/tgl: Updated Private PAT programming
Gen12 removes the target-cache and age fields from the private PAT
because MOCS now have the capability to set these itself. Only memory-type
field should be programmed in the ppat, the reminded bits are reserved.

Since now there are only 4 possible combinations, we could set only 4
PPAT and leave the reminded 4 as UC, but I left them as WB as we used
to have before.

Also these registers have been relocated to the 0x4800-0x481c range.
