4941f35b48 drm/i915: Make sure CCS YUV semiplanar format checks work
For CCS formats, the current DRM core check for YUV semiplanar formats
doesn't work; use an i915 specific function for that.

v2: Fix checkpatch warnings.

931cd348bb drm/i915: Skip rotated offset adjustment for unsupported modifiers
During framebuffer creation, we pre-compute offsets for 90/270 plane
rotation. However, only Y and Yf modifiers support 90/270 rotation. So,
skip the calculations for other modifiers.

To keep the gem buffer size check still working for tiled planes, factor
out the logic needed for rotation setup and skip only this part for
tiled planes other than Y/Yf.

v2: Add a bounds check WARN for the rotation info array.
v3: Keep the gem buffer size check working for tiled planes.

71df86f0fb drm/i915/tgl: Make sure FBs have a correct CCS plane stride
The CCS plane stride must be fixed on TGL, as it's not configurable for
the display. Instead the HW has a hardwired logic to determine it from
the main plane stride. Make sure userspace passes in the correct stride.

b3e57bccd6 drm/i915/tgl: Gen-12 render decompression
Gen-12 display decompression operates on Y-tiled compressed main surface.
The CCS is linear and has 4 bits of metadata for each main surface cache
line pair, a size ratio of 1:256. Gen-12 display decompression is
incompatible with buffers compressed by earlier GPUs, so make use of a new
modifier to identify gen-12 compression. Another notable change is that
render decompression is supported on all planes except cursor and on all
pipes. Start by adding render decompression support for [A,X]BGR888 pixel
formats.

v2: Fix checkpatch warnings (Lucas)
v3:
Rebase, disable color clear, styling changes and modify
intel_tile_width_bytes and intel_tile_height to handle linear CCS
v4:
- Use format block descriptors and the i915 specific func to get the
  subsampling for each color plane.
- Use helpers to convert between CCS and main planes.
v5:
- Fix subsampling returned by intel_fb_plane_get_subsampling() for
  the CCS plane of the first plane.
v6:
- Rebased on v2 of patch 4.
v7:
- Fix plane dimensions during FB check.

e7af909457 drm/i915: Add helpers to select correct ccs/aux planes
Using helpers instead of open coding this to select a CCS plane for a
main plane makes the code cleaner and less error-prone when the location
of CCS plane can be different based on the format (packed vs. YUV
semiplanar). The same applies to selecting an AUX plane which can be a
UV plane (for an uncompressed YUV semiplanar format), or a CCS plane.

773b4b5435 drm/i915: Move stuff from haswell_crtc_disable() into encoder .post_disable()
Move all of haswell_crtc_disable() into the encoder
.post_disable() hooks. Now we're left with just
calling the .disable() and .post_disable() hooks
back to back.

I chose to move the code into the .post_disable() hook instead
of the .disable() hook as most of the sequence is currently
implemented in the .post_disable() hook.

We should collapse it all down to just one hook and then the
encoders can drive the modeset sequence fully. But that may
need some further refactoring as we currently call the
ddi .post_disable() hook from mst code and we can't just
replace that with a call to the ddi .disable() hook.

Should also follow up with similar treatment for the enable
sequence but let's start here where it's easier.

b104e8b200 drm/i915: Pass cpu transcoder to assert_pipe()
In order to eliminate intel_pipe_to_cpu_transcoder() (and its
crtc->config usage) let's pass the cpu transcoder to
assert_pipe() so we don't have to do the pipe->cpu transcoder
lookup on HSW+.

On VLV/CHV this can get called during eDP init, which
happens before crtc->config->cpu_transcoder is even
populated. So currently we're always reading PIPECONF(A)
there even if we're trying to check the state of some
other pipe.

On glk+ the hardware gets confused if we disable FBC while
it's recompressing and we perform a plane update during the
same frame. The result is that top of the screen gets corrupted.

We can avoid that by giving the hardware enough time to finish
the FBC disable before we touch the plane registers. Ie. we need
an extra vblank wait after FBC disable.

8b1c78e06e drm/i915: Avoid calling i915_gem_object_unbind holding object lock
In the extreme case, we may wish to wait on an rcu-barrier to reap stale
vm to purge the last of the object bindings. However, we are not allowed
to use rcu_barrier() beneath the dma_resv (i.e. object) lock and do not
take lightly the prospect of unlocking a mutex deep in the bowels of the
routine. i915_gem_object_unbind() itself does not need the object lock,
and it turns out the callers do not need to the unbind as part of a
locked sequence around set-cache-level, so rearrange the code to avoid
taking the object lock in the callers.

ad45719101 drm/i915/display: Refactor intel_commit_modeset_disables()
Commit 9c722e17c1 ("drm/i915: Disable pipes in reverse order")
reverted the order that pipes gets disabled because of TGL
master/slave relationship between transcoders in MST mode.

But as stated in a comment in skl_commit_modeset_enables() the
enabling order is not always crescent, possibly causing previously
selected slave transcoder being enabled before master so another
approach will be needed to select a transcoder to master in MST mode.
It will be similar to the approach taken in port sync.

But instead of implement something like
intel_trans_port_sync_modeset_disables() to MST lets simply it and
iterate over all pipes 2 times, the first one disabling any slave and
then disabling everything else.
The MST bits will be added in another patch.

v2:
Not using crtc->active as it is deprecated

v3:
Removing is_trans_port_sync_mode() check, just check for
is_trans_port_sync_master() is enough

v4:
Adding and using is_trans_port_sync_slave(), otherwise non-port sync
pipes will be disabled in the first loop, what is not wrong but is
not what patch description promises

Assuming intel_crtc_arm_fifo_underrun() only gets called when
there's no pending plane updates we can utilize it on gen2 by
checking the active_planes bitmask so that we only re-enable
underrun reporting if some planes are active.
i915_fifo_underrun_reset_write() seems to have the necessary

7181f5c586 drm/i915: Clean up the gen2 "no planes -> underrun" workaround
We have the active_planes bitmask now so use it to properly
determine when some planes are visible for the gen2 underrun
workaround.

This let's us almost eliminate intel_post_enable_primary().
The manual underrun checks we can simply move into
intel_atomic_commit_tail() since they loop over all the pipes
already. No point in repeating the checks multiple times when
there are multiple pipes in the commit.

Change the calling convention to just pass the state+crtc and

We'll also do a quick s/if (old_primary_state)/if (new_primary_state)/
so that we'll be able to eliminate old_primary_state later. This
is fine since we always have either both old and new state or neither.

cc7a4cffea drm/i915: Fix frame start delay programming
Currently we're blindly poking at the frame start delay bits
in PIPECONF when trying to sanitize the hardware state. Those
bits decided to move elsewhere on HSW, so on many platforms
we're not doing anything at all here. Also we're forgetting
about the PCH transcoder entirely.

Add all the bit definitions for the various homes these bits
have had throughout the years, and reset them all to zero.

However I'm not entirely sure this is a safe thing to do. If
not I guess we'd want full readout+statecheck for this stuff.
For now let's stick to the current logic and hope for the
best.

f77021372e drm/i915: Preload LUTs if the hw isn't currently using them
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.

This causes explosions on any machine that boots up with pipes

1f594b209f drm/i915: Remove special case slave handling during hw programming, v3.
Now that we split plane_state which I didn't want to do yet, we can
program the slave plane without requiring the master plane.

On ivb fp16 scanout is slightly busted. The output from the plane will
have 1/4 the expected value. For the primary plane we would have to
use the pipe gamma or pipe csc to correct that which would affect all
the other planes as well, hence we simply choose not to expose fp16
on the ivb primary plane. On hsw the primary plane got fixed.

On gmch platforms I observed that the plane width must be below 2k
pixels with fp16 or else we get a corrupted image. This limitation
does not seem to be documented in bspec. I verified the exact limit
using the chv pipe B primary plane since it has windowing capability.
The stride limits are unaffected by fp16.

bb6ae9e653 drm/i915: Allow planes to declare their minimum acceptable cdclk
Various pixel formats and plane scaling impose additional constraints
on the cdclk frequency. Provide a new plane->min_cdclk() hook that
will be used to compute the minimum acceptable cdclk frequency for
each plane.

Annoyingly on some platforms the numer of active planes affects
this calculation so we must also toss in more planes into the
state when the number of active planes changes.

The sequence of state computation must also be changed:
1. check_plane() (updates plane's visibility etc.)
2. figure out if more planes now require update min_cdclk
   computaion
3. calculate the new min cdclk for each plane in the state
4. if the minimum of any plane now exceeds the current
   logical cdclk we recompute the cdclk
4. during cdclk computation take the planes' min_cdclk into
   accoutn
5. follow the normal cdclk programming to change the
   cdclk frequency. This may now require a modeset (except
   on bxt/glk in some cases), which either succeeds or
   fails depending on whether userspace has given
   us permission to perform a modeset or not.

1d5a95b5c9 drm/i915: Rework global state locking
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.

8f4b1068e7 drm/i915: Check some transcoder timing minimum limits
On ILK+ the documented min hdisplay is 64, min hblank is 32, and min
vblank is 5. On earlier platforms min hblank is also 32, and min
vblank is 3. Make sure the mode satisfies those limits.

There are further limits for HDMI and pfit use cases, but we'll check
for those in a more specific location.

993254292b drm/i915: Refactor timestamping constants update
Once we do the hw vs. uapi split we can no longer use
drm_atomic_helper_calc_timestamping_constants() as it'll
consult the uapi state instead of the hw state.

So let's just update the vblank timestamping constants whenever
we update the scanline offset. We use both to convert the hw
scanline count to something which matches the software timing
values.

First I thought to put these into intel_crtc_vblank_on() but
we may want to get the scanline counter value before that (eg.
from some early tracepoints), so let's stick to updating them
a bit earlier than intel_crtc_vblank_on().

0c06fa1560 drm/i915/dp: Add support of BT.2020 Colorimetry to DP MSA
When BT.2020 Colorimetry output is used for DP, we should program BT.2020
Colorimetry to MSA and VSC SDP. In order to handle colorspace of
drm_connector_state, it moves a calling of intel_ddi_set_pipe_settings()
function into intel_ddi_pre_enable_dp(). And it also rename
intel_ddi_set_pipe_settings() to intel_ddi_set_dp_msa().

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
Color Encoding Format and Content Color Gamut] while sending
BT.2020 Colorimetry signals we should program MSA MISC1 fields which
indicate VSC SDP for the Pixel Encoding/Colorimetry Format.

v2: Remove useless parentheses
v3: Addressed review comments from Ville
    - In order to checking output format and output colorspace on
      intel_dp_needs_vsc_sdp(), it passes entire intel_crtc_state struct
      value.
    - Remove a pointless variable.
v9: Addressed review comments from Ville
    - Remove a duplicated output color space from intel_crtc_state.
    - In order to handle colorspace of drm_connector_state, it moves a
      calling of intel_ddi_set_pipe_settings() function into
      intel_ddi_pre_enable_dp().

bdacf0871f drm/i915/tgl: Do modeset to enable and configure DC3CO exitline
DC3CO enabling B.Specs sequence requires to enable end configure
exit scanlines to TRANS_EXITLINE register, programming this register
has to be part of modeset sequence as this can't be change when
transcoder or port is enabled.
When system boots with only eDP panel there may not be real
modeset as BIOS has already programmed the necessary registers,
therefore it needs to force a modeset to enable and configure
DC3CO exitline.

v1: Computing dc3co_exitline crtc state from a DP encoder
    compute config. [Imre]
    Enabling and disabling DC3CO PSR2 transcoder exitline from
    encoder pre_enable and post_disable hooks. [Imre]
    Computing dc3co_exitline instead of has_dc3co_exitline bool. [Imre]
v2: Code refactoring for symmetry and to avoid exported function. [Imre]

    or it is not PSR2 capable in dc3co exitline compute_config. [Imre]

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.

2850748ef8 drm/i915: Pull i915_vma_pin under the vm->mutex
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.

ed06efb801 drm/i915/dp: Fix dsc bpp calculations, v5.
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.

Changes since v2:
- Handle fec_enable in intel_link_compute_m_n, so only data M/N is adjusted. (Ville)
- Fix initial hardware readout for FEC. (Ville)

2d20411e25 drm/i915: Don't advertise modes that exceed the max plane size
Modern platforms allow the transcoders hdisplay/vdisplay to exceed the
planes' max resolution. This has the nasty implication that modes on the
connectors' mode list may not be usable when the user asks for a
fullscreen plane. Seeing as that is the most common use case it seems
prudent to filter out modes that don't allow for fullscreen planes to
be enabled.

Let's do that in the connetor .mode_valid() hook so that normally
such modes are kept hidden but the user is still able to forcibly
specify such a mode if they know they don't need fullscreen planes.

This is in line with ealier policies regarding certain clock limits.
The idea is to prevent the casual user from encountering a mode that
would fail under typical conditions, but allow the expert user to
force things if they so wish.

Maybe in the future we should consider automagically using two
planes when one can't cover the entire screen? Wouldn't be a
great match for the current uapi with explicit planes though,
but I guess no worse than using two pipes (which we apparently
have to in the future anyway). Either that or we'd have to
teach userspace to do it for us.

bed34ef544 drm/i915: Bump skl+ max plane width to 5k for linear/x-tiled
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.

ef404bc659 drm/i915: stop conflating HAS_DISPLAY() and disabled display
Stop setting ->pipe_mask to zero when display is disabled, allowing us
to have different code paths for not actually having display hardware,
and having display hardware disabled. This lets us develop those two
avenues independently.

There are no functional changes for when there is no display. However,
all uses of for_each_pipe() and for_each_pipe_masked() will start
running for the disabled display case. Put one of the more significant
ones behind checks for INTEL_DISPLAY_ENABLED(), otherwise the cases
should not be hit with disabled display, or they seem benign. Fingers
crossed.

All in all, this might not be the ideal solution. In fact we may have
had something along the lines of this in the past, but we ended up
conflating the two cases. Possibly even by recommendation by yours
truly; I did not dare dig up that part of the history. But the perfect
