Implement low refresh rate (LRR) where we change the vblank
length by hand as requested, but otherwise keep the timing
generator running in non-VRR mode (ie. fixed refresh rate).
The panel itself must support VRR for this to work, and
only TGL+ has the double buffred TRANS_VTOTAL.VTOTAL that
we need to make the switch properly. The double buffer
latching happens at the start of transcoders undelayed
vblank. The other thing that we change is
TRANS_VBLANK.VBLANK_END but the hardware entirely ignores
that in DP mode. But I decided to keep writing it anyway
just to avoid more special cases in readout/state check.
v2: Document that TRANS_VBLANK.VBLANK_END is ignored by
the hardware
v3: Reconcile with VRR fastset
Adjust update_lrr flag behaviour
Make sure timings stay within VRR range
v4: Fix up update_m_n vs. update_lrr rebase fail (Manasi)
Drop DOUBLE_BUFFER_VACTIVE define as it's not needed (Manasi)

Make the seamless_m_n flag more like the update_pipe fastset
flag, ie. the flag will only be set if we need to do the seamless
M/N update, and in all other cases the flag is cleared. Also
rename the flag to update_m_n to make it more clear it's similar
to update_pipe.
I believe special casing seamless_m_n like this makes sense
as it also affects eg. vblank evasion. We can potentially avoid
some vblank evasion tricks, simplify some checks, and hopefully
will help with the VRR vs. M/N mess.

If we have to force the hardware to go through a full modeset
due to eg. cdclk reprogramming, we need to preserve
crtc_state->inherited for all crtcs that have not otherwise
gone through the whole compute_config() stuff after connectors
have been detected.
Otherwise eg. cdclk induced modeset glk_force_audio_cdclk()
will clear the inherited flag, and thus the first real commit
coming from userspace later on will not be forced through
the full .compute_config() path and so eg. audio state may
not get properly recomputed.
But instead of adding all kinds of ad-hoc crtc_state->inherited
preservation hacks all over, let's change things so that we
only clear it for the crtcs directly included in userspace/client
initiated commits.
Should be far less fragile since now we just need to remember
to flag the internal commits, and not worry about where new
crtcs might get pulled in.

In newer hardware versions (i.e. display version >= 14), the second
scaler doesn't support vertical scaling.
The current implementation of the scaling limits is simplified and
only occurs when the planes are created, so we don't know which scaler
is being used.
In order to handle separate scaling limits for horizontal and vertical
scaling, and different limits per scaler, split the checks in two
phases. We first do a simple check during plane creation and use the
best-case scenario (because we don't know the scaler that may be used
at a later point) and then do a more specific check when the scalers
are actually being set up.

Add an extra remapping step between the logical state of the LUTs
(hw.(de)gamma_lut) as specified via uapi/bigjoiner copy vs.
the actual state of the LUTs programmed into the hardware.
With this we should be finally able finish the (de)gamma
readout/state checker support for the remaining platforms
(ilk-skl) where the same hardware LUT can be positioned
either before or after the pipe CSC unit. Where we position
it depends on factors such as presence of the logical degamma
LUT, RGB vs. YCbCr output, full vs. limited RGB quantization
range.
Without the extra remapping step the state readout doesn't
really know whether the LUT read from the hardware is the
degamma or gamma LUT, and so we is unable to accurately store
it into our crtc state. With the remapping step we know
exactly where to put it given the order of the LUT vs. CSC
in the hardware state.
Only the initial hw->uapi state readout done during driver
load/resume still has the problem of not really knowing
what to do with the LUT(s). But we can just assume 1:1
mapping there and let subsequent commits fix things up.
Another benefit is that we now have a place for purely
internal LUTs, without complicating the bigjoiner uapi->hw
copy logic. This should prove useful for streamlining
glk degamma LUT handling.

The current implementation of the async flip wm0/ddb optimization
does not work at all. The biggest problem is that we skip the
whole intel_pipe_update_{start,end}() dance and thus never actually
complete the commit that is trying to do the wm/ddb change.
To fix this we need to move the do_async_flip flag to the crtc
state since we handle commits per-pipe, not per-plane.
Also since all planes can now be included in the first/last
"async flip" (which gets converted to a sync flip to do the
wm/ddb mangling) we need to be more careful when checking if
the plane state is async flip comptatible. Only planes doing
the async flip should be checked and other planes are perfectly
fine not adhereing to any async flip related limitations.
However for subsequent commits which are actually going do the
async flip in hardware we want to make sure no other planes
are in the state. That should never happen assuming we did our
job correctly, so we'll toss in a WARN to make sure we catch
any bugs here.

Currently the bigjoiner state copy logic is kind of
a byzantine mess.
Clean it up to operate in the following manner during a full
modeset:
1) master uapi -> hw state copy
2) master hw -> slave hw state copy
And during a non-modeset update we do:
1) master uapi -> hw state light copy
2) master hw -> slave hw state light copy
I think that is now easier to reason about since we never do
any kind of master uapi -> slave hw state copy short circuit
that could happen previously.
Obviously this does now depend on the master uapi->hw copy
always happening before the master hw -> slave hw copy, but
that is guaranteed by the fact that we always add both crtcs
to the state early, the crtcs are registered in pipe
order (so the compute_config loop happens in pipe order),
and the hardware requires the master pipe has to be lower
than the slave pipe as well. And for good measure we shall
add a check+WARN for this before doing the bigjoiner crtc
assignment.

Several of our i915 header files, have been including i915_reg.h. This
means that any change to i915_reg.h will trigger a full rebuild of
pretty much every file of the driver, even those that don't have any
kind of register access. Let's delete the i915_reg.h include from all
headers and add an explicit include from the .c files that truly
need the register definitions; those that need a definition of
i915_reg_t for a function definition can get it from i915_reg_defs.h
instead.
We also remove two non-register #define's (VLV_DISPLAY_BASE and
GEN12_SFC_DONE_MAX) into i915_reg_defs.h to allow us to drop the
i915_reg.h include from a couple of headers.
There's probably a lot more header dependency optimization possible, but
the changes here roughly cut the number of files compiled after 'touch
i915_reg.h' in half --- a good first step.

While converting the rest of the driver to use GRAPHICS_VER() and
MEDIA_VER(), following what was done for display, some discussions went
back on what we did for display:
1) Why is the == comparison special that deserves a separate
macro instead of just getting the version and comparing directly
like is done for >, >=, <=?
2) IS_DISPLAY_RANGE() is weird in that it omits the "_VER" for
brevity. If we remove the current users of IS_DISPLAY_VER(), we
could actually repurpose it for a range check
With (1) there could be an advantage if we used gen_mask since multiple
conditionals be combined by the compiler in a single and instruction and
check the result. However a) INTEL_GEN() doesn't use the mask since it
would make the code bigger everywhere else and b) in the cases it made
sense, it also made sense to convert to the _RANGE() variant.
So here we repurpose IS_DISPLAY_VER() to work with a [ from, to ] range
like was the IS_DISPLAY_RANGE() and convert the current IS_DISPLAY_VER()
users to use == and != operators. Aside from the definition changes,
this was done by the following semantic patch:

Replace the use of mode->private_flags with a truly private bitmaks
in our own crtc state. We also need a copy in the crtc itself so the
vblank code can get at it. We already have scanline_offset in there
for a similar reason, as well as the vblank->hwmode which is assigned
via drm_calc_timestamping_constants(). Fortunately we now have a
nice place for doing the crtc_state->crtc copy in
intel_crtc_update_active_timings() which gets called both for
modesets and init/resume readout.
The one slightly iffy spot is the INHERITED flag which we want to
preserve until userspace/fb_helper does the first proper commit after
actually calling .detecti() on the connectors. Otherwise we don't have
the full sink capabilities (audio,infoframes,etc.) when .compute_config()
gets called and thus we will fail to enable those features when the
first userspace commit happens. The only internal commit we do prior to
that should be from intel_initial_commit() and there we can simply
preserve the INHERITED flag from the readout.

Pre-allocate command buffer in atomic_commit using intel_dsb_prepare
function which also includes pinning and map in cpu domain.
No functional change is dsb write/commit functions.
Now dsb get/put function is removed and ref-count mechanism is
not needed. Below dsb api added to do respective job mentioned
below.
intel_dsb_prepare - Allocate, pin and map the buffer.
intel_dsb_cleanup - Unpin and release the gem object.
RFC: Initial patch for design review.
v2: included _init() part in _prepare(). [Daniel, Ville]
v3: dsb_cleanup called after cleanup_planes. [Daniel]
v4: dsb structure is moved to intel_crtc_state from intel_crtc. [Maarten]
v5: dsb get/put/ref-count mechanism removed. [Maarten]
v6: Based on review feedback following changes are added,
- replaced intel_dsb structure by pointer in intel_crtc_state. [Maarten]
- passing intel_crtc_state to dsp-api to simplify the code. [Maarten]
- few dsb functions prototype modified to simplify code.
v7: added few cosmetic changes suggested by Jani and null check for
crtc_state in dsb_cleanup removed as suggested by Maarten.
v8: changed the function parameter to intel_crtc_state* of
ivb_load_lut_ext_max() from intel_crtc. [Maarten]

Let's convert cdclk_state to be a proper global state. That allows
us to use the regular atomic old vs. new state accessor, hopefully
making the code less confusing.
We do have to deal with a few more error cases in case the cdclk
state duplication fails. But so be it.

Our current global state handling is pretty ad-hoc. Let's try to
make it better by imitating the standard drm core private object
approach.
The reason why we don't want to directly use the private objects
is locking; Each private object has its own lock so if we
introduce any global private objects we get serialized by that
single lock across all pipes. The global state apporoach instead
uses a read/write lock type of approach where each individual
crtc lock counts as a read lock, and grabbing all the crtc locks
allows one write access.

Recent improvements in the state tracking in i915 caused PSR to not be
enabled when reusing firmware/BIOS modeset, this is due to all initial
commits returning ealier in intel_atomic_check() as needs_modeset()
is always false.
To fix that here forcing the state compute phase in CRTC that is
driving the eDP that supports PSR once. Enable or disable PSR do not
require a fullmodeset, so user will still experience glitch free boot
process plus the power savings that PSR brings.
It was tried to set mode_changed in intel_initial_commit() but at
this point the connectors are not registered causing a crash when
computing encoder state.
v2:
- removed function return
- change arguments to match intel_hdcp_atomic_check
v3:
- replaced drm includes in intel_psr.h by forward declaration(Jani)

On TGL the blending of all the streams have moved from DDI to
transcoder, so now every transcoder working over the same MST port must
send its stream to a master transcoder and master will send to DDI
respecting the time slots.
So here adding all the CRTCs that shares the same MST stream if
needed and computing their state again, it will pick the lowest
pipe/transcoder among the ones in the same stream to be master.
Most of the time skl_commit_modeset_enables() enables pipes in a
crescent order but due DDB overlapping it might not happen, this
scenarios will be handled in the next patch.
v2:
- Using recently added intel_crtc_state_reset() to set
mst_master_transcoder to invalid transcoder for all non gen12 & MST
code paths
- Setting lowest pipe/transcoder as master, previously it was the
first one but setting a predictable one will help in future MST e
port sync integration
- Moving to intel type as much as we can
v3:
- Now intel_dp_mst_master_trans_compute() returns the MST master transcoder
- Replaced stdbool.h by linux/types.h
- Skip the connector being checked in
intel_dp_mst_atomic_master_trans_check()
- Using pipe instead of transcoder to compute MST master
v4:
- renamed connector_state to conn_state
v5:
- Improved the parameters of intel_dp_mst_master_trans_compute() to
simply code
- Added call drm_atomic_add_affected_planes() in
intel_dp_mst_atomic_master_trans_check() as helper could not do it
for us
- Removed "if (ret)" left over from v3 changes
v6:
- handled ret == I915_MAX_PIPES case in compute

intel_connector_needs_modeset() will be used outside of
intel_display.c in a future patch so it would only be necessary to
remove the state and add the prototype to the header file.
But while at it, I simplified the arguments and moved it to a better
place intel_atomic.c.
No behavior changes intended here.
v3:
- removed digital from exported version of intel_connector_needs_modeset
- rollback connector to drm type
v4:
- Renamed new_connector_state to new_conn_state
- Going back to drm_connector_state in
intel_encoders_update_prepare/complete as we also have
intel_tv_connector_state

The LUTs are single buffered so in order to program them without
tearing we'd have to do it during vblank (actually to be 100%
effective it has to happen between start of vblank and frame start).
We have no proper mechanism for that at the moment so we just
defer loading them after the vblank waits have happened. That
is not quite sufficient (especially when committing multiple pipes
whose vblanks don't line up) so the LUT load will often leak into
the following frame causing tearing.
However in case the hardware wasn't previously using the LUT we
can preload it before setting the enable bit (which is double
buffered so won't tear). Let's determine if we can do such
preloading and make it happen. Slight variation between the
hardware requires some platforms specifics in the checks.
Hans is seeing ugly colored flash on VLV/CHV macchines (GPD win
and Asus T100HA) when the gamma LUT gets loaded for the first
time as the BIOS has left some junk in the LUT memory.

Now that we separated everything into uapi and hw, it's
time to make the split definitive. Remove the union and
make a copy of the hw state on modeset and fastset.
Color blobs are copied in crtc atomic_check(), right
before color management is checked.
Changes since v1:
- Copy all blobs immediately after drm_atomic_helper_check_modeset().
- Clear crtc_state->hw on disable, instead of using clear_intel_crtc_state().
Changes since v2:
- Use intel_crtc_free_hw_state + clear in intel_crtc_disable_noatomic().
- Make a intel_crtc_prepare_state() function that clears the crtc_state
and copies hw members.
- Remove setting uapi.adjusted_mode, we now have a direct call to
drm_calc_timestamping_constants().
Changes since v3:
- Rename prefix copy_hw_to_uapi_state() with intel_crtc.
- Copy color blobs to uapi as well.
- Add a intel_crtc_copy_uapi_to_hw_state_nomodeset() function for clarity.
Changes since v4:
- Copy hw.adjusted_mode back to uapi.adjusted_mode, to shut up
the call to drm_calc_timestamping_constants() in
drm_atomic_helper_update_legacy_modeset_state().
- Use drm_property_replace_blob (Ville).

So far we've sort of protected the global state under dev_priv with
the connection_mutex. I wan to change that so that we can change the
cdclk even for pure plane updates. To that end let's formalize the
protection of the global state to follow what I started with the cdclk
code already (though not entirely properly) such that any crtc mutex
will suffice as a read lock, and all crtcs mutexes act as the write
lock.
We'll also pimp intel_atomic_state_clear() to clear the entire global
state, so that we don't accidentally leak stale information between
the locking retries.
As a slight optimization we'll only lock the crtc mutexes to protect
the global state, however if and when we actually have to poke the
hw (eg. if the actual cdclk changes) we must serialize commits
across all crtcs so that a parallel nonblocking commit can't get
ahead of the cdclk reprogamming. We do that by adding all crtcs to
the state.
TODO: the old global state examined during commit may still
be a problem since it always looks at the _latest_ swapped state
in dev_priv. Need to add proper old/new state for that too I think.
