We need to insert stuff between the plane and crtc .atomic_check()
drm_atomic_helper_check_planes() doesn't allow us to do that so
stop using it and hand roll the loops instead.

Function intel_dp_setup_hdr_metadata_infoframe_sdp handles Infoframe SDP
header and data block setup for HDR Static Metadata. It enables writing of
HDR metadata infoframe SDP to panel. Support for HDR video was introduced
in DisplayPort 1.4. It implements the CTA-861-G standard for transport of
static HDR metadata. The HDR Metadata will be provided by userspace
compositors, based on blending policies and passed to the driver through
a blob property.
Because each of GEN11 and prior GEN11 have different register size for
HDR Metadata Infoframe SDP packet, it adds and uses different register
size.
Setup Infoframe SDP header and data block in function
intel_dp_setup_hdr_metadata_infoframe_sdp for HDR Static Metadata as per
dp 1.4 spec and CTA-861-F spec.
As per DP 1.4 spec, 2.2.2.5 SDP Formats. It enables Dynamic Range and
Mastering Infoframe for HDR content, which is defined in CTA-861-F spec.
According to DP 1.4 spec and CEA-861-F spec Table 5, in order to transmit
static HDR metadata, we have to use Non-audio INFOFRAME SDP v1.3.

It attaches the colorspace connector property to a DisplayPort connector.
Based on colorspace change, modeset will be triggered to switch to a new
colorspace.
And in order to distinguish colorspace bwtween DP and HDMI connector, it
adds a handling of drm_mode_create_dp_colorspace_property() to
intel_attach_colorspace_property().
Based on colorspace property value create a VSC SDP packet with appropriate
colorspace. This would help to enable wider color gamut like BT2020 on a

As per DP 1.4a spec section 2.2.4 [MSA Data Transport]
The MSA data that the DP Source device transports for reproducing the main
video stream. Attribute data is sent once per frame during the main video
stream’s vertical blanking period.
In order to distinguish needed colorimetry for VSC SDP, it adds
intel_dp_needs_vsc_sdp function.
If the output colorspace requires vsc sdp or output format is YCbCr 4:2:0,
it uses MSA with VSC SDP.
As per DP 1.4a spec section 2.2.4.3 [MSA Field for Indication of

We have a src and dect rectangle, use it instead of relying on
the core drm properties.
Because the core by default clips the src/dst properties, after
the drm_atomic_helper_check_plane_state() we manually set the
unclipped src/dst rectangles. We still need the call for
visibility checks, but this way we are able to use the src/dst
rects in the check/commit code.
This removes the special case in the watermark code for cursor w/h.

Premature gamma lut prepration and loading which was getting
reflected in first modeset causing different colors on
screen during boot.
Issue: In BIOS, gamma is disabled by default. However, legacy read_luts()
was setting crtc_state->base.gamma_lut and gamma_lut was programmed
with junk values which led to visual artifacts (different
colored screens instead of usual black during boot).
Fix: Calling read_luts() only when gamma is enabled which will happen
after first modeset.
This fix is independent from the revert 1b8588741fdc ("Revert
"drm/i915/color: Extract icl_read_luts()"") and should fix different colors
on screen in legacy platforms too.
v2:
-Added gamma_enable checks inside read_luts() [Ville/Jani N]
-Corrected gamma enable check for CHV [Ville]
v3:
-Added check in ilk_read_luts() [Ville]
-Simplified gamma enable check for CHV [Ville]

DC3CO is useful power state, when DMC detects PSR2 idle frame
while an active video playback, playing 30fps video on 60hz panel
is the classic example of this use case.
B.Specs:49196 has a restriction to enable DC3CO only for Video Playback.
It will be worthy to enable DC3CO after completion of each pageflip
and switch back to DC5 when display is idle because driver doesn't
differentiate between video playback and a normal pageflip.
We will use Frontbuffer flush call tgl_dc3co_flush() to enable DC3CO
state only for ORIGIN_FLIP flush call, because DC3CO state has primarily
targeted for VPB use case. We are not interested here for frontbuffer
invalidates calls because that triggers PSR2 exit, which will
explicitly disable DC3CO.
DC5 and DC6 saves more power, but can't be entered during video
playback because there are not enough idle frames in a row to meet
most PSR2 panel deep sleep entry requirement typically 4 frames.
As PSR2 existing implementation is using minimum 6 idle frames for
deep sleep, it is safer to enable DC5/6 after 6 idle frames
(By scheduling a delayed work of 6 idle frames, once DC3CO has been
enabled after a pageflip).
After manually waiting for 6 idle frames DC5/6 will be enabled and
PSR2 deep sleep idle frames will be restored to 6 idle frames, at this
point DMC will triggers DC5/6 once PSR2 enters to deep sleep after
6 idle frames.
In future when we will enable S/W PSR2 tracking, we can change the
PSR2 required deep sleep idle frames to 1 so DMC can trigger the
DC5/6 immediately after S/W manual waiting of 6 idle frames get
complete.

The officially validated plane width limit is 4k on skl+, however
we already had people using 5k displays before we started to enforce
the limit. Also it seems Windows allows 5k resolutions as well
(though not sure if they do it with one plane or two).
According to hw folks 5k should work with the possible
exception of the following features:
- Ytile (already limited to 4k)
- FP16 (already limited to 4k)
- render compression (already limited to 4k)
- KVMR sprite and cursor (don't care)
- horizontal panning (need to verify this)
- pipe and plane scaling (need to verify this)
So apart from last two items on that list we are already
fine. We should really verify what happens with those last
two items but I don't have a 5k display on hand atm so it'll
have to wait.
In the meantime let's just bump the limit back up to 5k since
several users have already been using it without apparent issues.
At least we'll be no worse off than we were prior to lowering
the limits.

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.

Forgo the struct_mutex serialisation for i915_active, and interpose its
own mutex handling for active/retire.
This is a multi-layered sleight-of-hand. First, we had to ensure that no
active/retire callbacks accidentally inverted the mutex ordering rules,
nor assumed that they were themselves serialised by struct_mutex. More
challenging though, is the rule over updating elements of the active
rbtree. Instead of the whole i915_active now being serialised by
struct_mutex, allocations/rotations of the tree are serialised by the
i915_active.mutex and individual nodes are serialised by the caller
using the i915_timeline.mutex (we need to use nested spinlocks to
interact with the dma_fence callback lists).
The pain point here is that instead of a single mutex around execbuf, we
now have to take a mutex for active tracker (one for each vma, context,
etc) and a couple of spinlocks for each fence update. The improvement in
fine grained locking allowing for multiple concurrent clients
(eventually!) should be worth it in typical loads.
v2: Add some comments that barely elucidate anything :(

Replace the struct_mutex requirement for pinning the i915_vma with the
local vm->mutex instead. Note that the vm->mutex is tainted by the
shrinker (we require unbinding from inside fs-reclaim) and so we cannot
allocate while holding that mutex. Instead we have to preallocate
workers to do allocate and apply the PTE updates after we have we
reserved their slot in the drm_mm (using fences to order the PTE writes
with the GPU work and with later unbind).
In adding the asynchronous vma binding, one subtle requirement is to
avoid coupling the binding fence into the backing object->resv. That is
the asynchronous binding only applies to the vma timeline itself and not
to the pages as that is a more global timeline (the binding of one vma
does not need to be ordered with another vma, nor does the implicit GEM
fencing depend on a vma, only on writes to the backing store). Keeping
the vma binding distinct from the backing store timelines is verified by
a number of async gem_exec_fence and gem_exec_schedule tests. The way we
do this is quite simple, we keep the fence for the vma binding separate
and only wait on it as required, and never add it to the obj->resv
itself.
Another consequence in reducing the locking around the vma is the
destruction of the vma is no longer globally serialised by struct_mutex.
A natural solution would be to add a kref to i915_vma, but that requires
decoupling the reference cycles, possibly by introducing a new
i915_mm_pages object that is own by both obj->mm and vma->pages.
However, we have not taken that route due to the overshadowing lmem/ttm
discussions, and instead play a series of complicated games with
trylocks to (hopefully) ensure that only one destruction path is called!
v2: Add some commentary, and some helpers to reduce patch churn.

This reverts commit 4eaceea3a00f8e936a7f48dcd0c975a57f88930f.
Several userspace clients (modesetting ddx and mutter+wayland at least)
handle encoder.possible_crtcs incorrectly. What they essentially do is
the following:
possible_crtcs = ~0;
for_each_possible_encoder(connector)
possible_crtcs &= encoder->possible_crtcs;
Ie. they calculate the intersection of the possible_crtcs
for the connector when they really should be calculating the
union instead.
In our case each MST encoder now has just one unique bit set,
and so the intersection is always zero. The end result is that
MST connectors can't be lit up because no crtc can be found to
drive them.
I've submitted a fix for the modesetting ddx [1], and complained
on #wayland about mutter, so hopefully the situation will improve
in the future. In the meantime we have regression, and so must go
back to the old way of misconfiguring possible_crtcs in the kernel.

There was a integer wraparound when mode_clock became too high,
and we didn't correct for the FEC overhead factor when dividing,
with the calculations breaking at HBR3.
As a result our calculated bpp was way too high, and the link width
limitation never came into effect.
Print out the resulting bpp calcululations as a sanity check, just
in case we ever have to debug it later on again.
We also used the wrong factor for FEC. While bspec mentions 2.4%,
all the calculations use 1/0.972261, and the same ratio should be
applied to data M/N as well, so use it there when FEC is enabled.
This fixes the FIFO underrun we are seeing with FEC enabled.
