Add intel_modeset_pipes_in_mask_early() to modeset a provided set of
pipes, used in a follow-up patch.
As opposed to intel_modeset_all_pipes() which modesets only the active
pipes - others don't requiring programming the HW - modeset all enabled
pipes in intel_modeset_pipes_in_mask_early() which may need to recompute
their state even if they are not active (that is in the DPMS off state).
While at it add DocBook descriptions for the two exported functions.
v2:
- Add a flag controlling if active planes are force updated as well.
- Add DockBook descriptions.
v3:
- For clarity use _early/_late suffixes for the exported functions
instead of the update_active_planes parameter. (Ville)
v4:
- In intel_modeset_pipes_in_mask_early() update only the crtc
flags relevant to the early phase. (Ville)
- Rename intel_modeset_all_pipes() in a separate patch.

Limit the output link bpp in DSC mode to the link_config_limits
link.min_bpp_x16 .. max_bpp_x16 range the same way it's done in non-DSC
mode. Atm this doesn't make a difference, the link bpp range being
0 .. max pipe bpp, but a follow-up patch will need a way to reduce max
link bpp below its current value.
v2:
- Add to_bpp_int_roundup() instead of open coding it. (Jani)

In non-DSC mode the link bpp can be set in 2*3 bpp steps in the pipe bpp
range, while in DSC mode it can be set in 1/16 bpp steps to any value
up to the maximum pipe bpp. Update the limits accordingly in both modes
to prepare for a follow-up patch which may need to reduce the max link
bpp value and starts to check the link bpp limits in DSC mode as well.
While at it add more detail to the link limit debug print and print it
also for DSC mode.
v2:
- Add to_bpp_frac_dec() instead of open coding it. (Jani)
v3: (Ville)
- Add BPP_X16_FMT / BPP_X16_ARG.
- Add TODO: comment about initializing the DSC link bpp limits earlier.

Computing the non-DSC mode link config is redundant once it's determined
that DSC will be needed, so skip computing it. In a follow-up patch this
simplifies setting the link limits which are dependent on the DSC vs.
non-DSC mode.
While at it sanitize the debug print about the MST DSC fallback path,
making it similar to the SST DSC one.

A follow-up patch will need to limit the output link bpp both in the
non-DSC and DSC configuration, so track the pipe and link bpp limits
separately in the link_config_limits struct.
Use .4 fixed point format for link bpp matching the 1/16 bpp granularity
in DSC mode and for now keep this limit matching the pipe bpp limit.
v2: (Jani)
- Add to_bpp_int(), to_bpp_x16() helpers instead of opencoding them.

Normally we could be in a deep PkgC state all the way up to the
point when DSB starts its execution at the transcoders undelayed
vblank. The DSB will then have to wait for the hardware to
wake up before it can execute anything. This will waste a huge
chunk of the vblank time just waiting, and risks the DSB execution
spilling into the vertical active period. That will be very bad,
especially when programming the LUTs as the anti-collision logic
will cause DSB to corrupt LUT writes during vertical active.
To avoid these problems we can instruct the DSB to pre-wake the
display engine on a specific scanline so that everything will
be 100% ready to go when we hit the transcoder's undelayed vblank.
One annoyance is that the scanline is specified as just that,
a single scanline. So if we happen to start the DSB execution
after passing said scanline no DEwake will happen and we may drop
back into some PkgC state before reaching the transcoder's undelayed
vblank. To prevent that we'll use the "force DEwake" bit to manually
force the display engine to stay awake. We'll then have to clear
the force bit again after the DSB is done (the force bit remains
effective even when the DSB is otherwise disabled).

We want to start the DSB execution from the transcoder's undelayed
vblank, so in order to guarantee atomicity with the all the other
mmio register writes we need to evade both vblanks.
Note that currently we don't add any vblank delay, so this is
effectively a nop. But in the future when we start to program
double buffered registers from the DSB we'll need to delay the
pipe's vblank to provide the register programming "window2"
for the DSB.

Loading LUTs with the DSB outside of vblank doesn't really
work due to the palette anti-collision logic. Apparently the
DSB register writes don't get stalled like CPU mmio writes
do and instead we end up corrupting the LUT entries. Disabling
the anti-collision logic would allow us to successfully load
the LUT outside of vblank, but presumably that risks the LUT
reads from the scanout (temporarily) getting corrupted data
from the LUT instead.
The anti-collision logic isn't active during vblank so that
is when we can successfully load the LUT with the DSB. That is
what we want to do anyway to avoid tearing.

Commit ade8a0f59844 ("drm/i915: Make all GPU resets atomic") added a
preempt disable section over the hardware reset callback to prepare the
driver for being able to reset from atomic contexts.
In retrospect I can see that the work item at a time was about removing
the struct mutex from the reset path. Code base also briefly entertained
the idea of doing the reset under stop_machine in order to serialize
userspace mmap and temporary glitch in the fence registers (see
eb8d0f5af4ec ("drm/i915: Remove GPU reset dependence on struct_mutex"),
but that never materialized and was soon removed in 2caffbf11762
("drm/i915: Revoke mmaps and prevent access to fence registers across
reset") and replaced with a SRCU based solution.
As such, as far as I can see, today we still have a requirement that
resets must not sleep (invoked from submission tasklets), but no need to
support invoking them from a truly atomic context.
Given that the preemption section is problematic on RT kernels, since the
uncore lock becomes a sleeping lock and so is invalid in such section,
lets try and remove it. Potential downside is that our short waits on GPU
to complete the reset may get extended if CPU scheduling interferes, but
in practice that probably isn't a deal breaker.
In terms of mechanics, since the preemption disabled block is being
removed we just need to replace a few of the wait_for_atomic macros into
busy looping versions which will work (and not complain) when called from
non-atomic sections.

`strncpy` is deprecated for use on NUL-terminated destination strings [1].
We should prefer more robust and less ambiguous string interfaces.
Since `chan->base.name` is expected to be NUL-terminated, a suitable
replacement is `strscpy` [2] due to the fact that it guarantees
NUL-termination on the destination buffer without also unnecessarily
NUL-padding (since `chan` is kzalloc'd already).

During the suspend process dc_set_power_state() will use kzalloc
to allocate memory, but this potentially fails with memory pressure.
If it fails, the suspend should be aborted.

dc->caps.color.mpc.gamut_remap says there is a post-blending color block
for gamut remap matrix for DCN3 HW family and newer versions. However,
those drivers still follow DCN10 programming that remap stream
gamut_remap_matrix to DPP (pre-blending).
To enable pre-blending and post-blending gamut_remap matrix supports at
the same time, set stream gamut_remap to MPC and plane gamut_remap to
DPP for DCN families that support both.
It was tested using IGT KMS color tests for DRM CRTC CTM property and it
preserves test results.

To disable AGP, the start needs to be set to a higher
value than the end. Set a default disable value for
the AGP aperture and allow the IP specific GMC code
to enable it selectively be calling amdgpu_gmc_agp_location().

The BOT register needs to be larger than the TOP register
for this to be properly disabled. The lower 22 bits
of the BOT address are always 0 and the lower 22 bits of
the TOP register are always 1 so you need to make
the upper bits of BOT larger than the upper bits of BOT.

[why]
The current ODM change detection only compares first two ODM slices.
If there are 4 ODM slices and the change is within the last two slices, the
logic fails to detect ODM change and cause us to skip ODM programming
unexpectedly.
[how]
Add a is ODM topology changed resource interface to check any ODM
topology changes with a more generic method.

[why]
There is a corner use case where the same plane pointer can be added into
dc state twice. In addition to plane state pointer check we also need to match
primary pipe before identifying the same plane.

[why]
acquire_free_pipe_as_secondary_opp_head function pointer is not
assigned. This causes ODM mode to be disabled after enabling
windowed MPO ODM capability on DCN321.
[how]
assign the correct function to the function pointer.
