0bcbcba782 drm/i915/display: Program PSR2 selective fetch registers
Another step towards PSR2 selective fetch, here programming plane
selective fetch registers and MAN_TRK_CTL enabling selective fetch but
for now it is fetching the whole area of the planes.
The damaged area calculation will come as next and final step.

v2:
- removed warn on when no plane is visible in state
- removed calculations using plane damaged area in
intel_psr2_program_plane_sel_fetch()

v3:
- do not shift 16 positions the plane dst coordinates, only src is
shifted

v4:
- only setting PLANE_SEL_FETCH_CTL_ENABLE and MCURSOR_MODE in
PLANE_SEL_FETCH_CTL

v5:
- not masking bits for cursor

a007138e89 drm/i915: Skip aux plane stuff when there is no aux plane
when the hardware isn't going to use the aux plane there's no
real point in dealing with the relevant hardware restrictions.
So let's just skip all that when not necessary.

We can now also remove the offset=~0xfff behaviour for unused
color planes. Let's just zero out everyting so as to not leave
stale garbage behind to confuse people debugging the code.

v2: Explicitly set AUX_DIST to zero when there is no aux plane

79148ce4b2 drm/i915: Set all unused color plane offsets to ~0xfff again
When the number of potential color planes grew to 4 we stopped
setting all unused color plane offsets to ~0xfff. The code
still tries to do this, but actually does nothing since the
loop limits are bogus.

skl_check_main_surface() actually depends on this ~0xfff
behaviour as it will make sure to move the main surface
offset below the aux surface offset because the hardware
AUX_DIST must be a non-negative value [1], and for simplicity
it doesn't bother checking if the AUX plane is actually
needed or not. So currently it may end up shuffling the
main surface around based on some stale leftover AUX offset.

The skl+ plane code also just blindly calculates the AUX_DIST
whether or not the AUX plane is actually needed by the hw or
not, and that too will now potentially use some stale AUX
surface offset in the calculation. Would seem nicer to
guarantee a consistent non-negative AUX_DIST always.

So bring back the original ~0xfff offset behaviour for
unused color planes. Though it doesn't seem super likely
that this inconsistency would cause any real issues.

f9e76a6e68 drm/i915: Add an encoder hook to sanitize its state during init/resume
Atm, if a full modeset is performed during the initial modeset the link
training will happen with uninitialized max DP rate and lane count. Make
sure the corresponding encoder state is initialized by adding an encoder
hook called during driver init and system resume.

A better alternative would be to store all states in the CRTC state and
make this state available for the link re-training code. Also instead of
the DPCD read in the hook there should be really a proper sink HW
readout in place. Both of these require a bigger rework, so for now opting
for this minimal fix to make at least full initial modesets work.

The patch is based on
https://patchwork.freedesktop.org/patch/101473/?series=10354&rev=3

v2: (Ville)
- s/sanitize_state/sync_state/
- No point in calling the hook when CRTC is disabled, remove the call.
- No point in calling the hook for MST, remove it.

v3: Check only DPCD_REV to avoid clobbering intel_dp->dpcd. (Ville)

* DSI support for sm8150/sm8250
* Support for per-process GPU pagetables (finally!) for a6xx.
  There are still some iommu/arm-smmu changes required to
  enable, without which it will fallback to the current single
  pgtable state.  The first part (ie. what doesn't depend on
  drm side patches) is queued up for v5.10[1].
* DisplayPort support.  Userspace DP compliance tool support
  is already merged in IGT[2]

ef80c1a1d2 drm/i915: Fix state checker hw.active/hw.enable readout
Previously intel_dump_pipe_config() used to dump the full crtc state
whether or not the crtc was logically enabled or not. As that meant
occasionally dumping confusing stale garbage I changed it to
check whether the crtc is logically enabled or not. However I did
not realize that the state checker readout code does not
populate crtc_state.hw.{active,enabled}. Hence the state checker
dump would only give us a full dump of the sw state but not the hw
state. Fix that by populating those bits of the hw state as well.

33267703df drm/i915/dsi: Enable software vblank counter
In case of DSI cmd mode, we get hw vblank counter updated after the TE
comes in, if we try to read the hw vblank counter in te handler we
wouldnt have the udpated vblank counter yet. This will lead to a state
where we would send the vblank event to the user space in the next te,
though the frame update would have completed in the first TE duration
itself. Hence switch to using software timestamp based vblank counter.

b81dddb909 drm/i915: Reduce INTEL_DISPLAY_ENABLED to just treat outputs as disconnected
Since the display hardware is all there even when INTEL_DISPLAY_ENABLED
return false we have to be capable of shutting it down cleanly so
as to not anger the hw. To that end let's reduce the effect of
!INTEL_DISPLAY_ENABLE to just treating all outputs as disconnected.
Should prevent anyone from automagically enabling any of them, while
still allowing us to cleanly shut them down.

da27bd41d0 drm/i915: Reduce INTEL_DISPLAY_ENABLED to just removing the outputs
Having a mode where the display hardware is present but we try
to pretend it isn't just leads to massive headaches when trying
to reason what the fallout might be from skipping some random
bits of programming.

Let's just neuter INTEL_DISPLAY_ENABLED so that we treat the
hardware as fully present, except we just don't register any
outputs. That's still rather sketchy if the outputs are already
enabled when the driver is loaded. I think the simplest solution
would be to probe everything as normal and just return
disconnected" from all .detect() hooks. That would avoid anything
automagically enabling those outputs, but the driver could then
shut things down using the normal codepaths.

0c4c801b31 drm/i915: fix regression leading to display audio probe failure on GLK
In commit 4f0b4352bd ("drm/i915: Extract cdclk requirements checking

intel_modeset_checks(), was reversed. This broke the mechanism to
immediately force a new CDCLK minimum, and lead to driver probe
errors for display audio on GLK platform with 5.9-rc1 kernel. Fix
the issue by moving intel_modeset_checks() call later.

[vsyrjala: It also broke the ability of planes to bump up the cdclk
and thus could lead to underruns when eg. flipping from 32bpp to
64bpp framebuffer. To be clear, we still compute the new cdclk
correctly but fail to actually program it to the hardware due to
intel_set_cdclk_{pre,post}_plane_update() not getting called on
account of state->modeset==false.]

6e43e276b8 drm/i915: Initial implementation of PSR2 selective fetch
All GEN12 platforms supports PSR2 selective fetch but not all GEN12
platforms supports PSR2 hardware tracking(aka RKL).

This feature consists in software programming registers with the
damaged area of each plane this way hardware will only fetch from
memory those areas and sent the PSR2 selective update blocks to panel,
saving even more power.

But as initial step it is only enabling the full frame fetch at
every flip, the actual selective fetch part will come in a future
patch.

Also this is only handling the page flip side, it is still completely
missing frontbuffer modifications, that is why the
enable_psr2_sel_fetch parameter was added.

v3:
- calling intel_psr2_sel_fetch_update() during the atomic check phase

ddff9a602e drm/i915/rkl: Handle HTI
If HTI (also sometimes called HDPORT) is enabled at startup, it may be
using some of the PHYs and DPLLs making them unavailable for general
usage.  Let's read out the HDPORT_STATE register and avoid making use of
resources that HTI is already using.

v2:
 - Fix minor checkpatch warnings

v3:
 - Just readout HDPORT_STATE register once during init and then parse it
   later as needed.
 - Add a 'has_hti' device info flag to track whether we should readout
   HDPORT_STATE or not.  We can skip the platform/flag tests later since
   the hti_state in dev_priv will remain 0 for platforms it does not
   apply to.
 - Move PLL masking into icl_get_combo_phy_dpll() since at the moment
   RKL is the only platform that has HTI.  (Jose)

90f8ed85c6 drm/i915/sdvo: Implement limited color range for SDVO HDMI properly
The SDVO/HDMI port register limited color range bit can only be used
with TMDS encoding and not SDVO encoding, ie. to be used only when
using the port as a HDMI port as opposed to a SDVO port. The SDVO
spec does have a note that some GMCHs might allow that, but gen4
bspec vehemently disagrees. I suppose on ILK+ it might work since
the color range handling is on the CPU side rather than on the PCH
side, so there is no clear linkage between the TMDS vs. SDVO
encoding and color range. Alas, I have no hardware to test that
theory.

To implement limited color range support for SDVO->HDMI we need to
ask the SDVO device to do the range compression. Do so, but first
check if the device even supports the colorimetry selection.

ddf08d320d drm/i915/fbc: Enable fbc on i865
Unlike all the other pre-snb desktop platforms i865 actually
supports FBC. Let's enable it.

Quote from the spec:
"DevSDG provides the same Run-Length Encoded Frame Buffer
 Compression (RLEFBC) function as exists in DevMGM."

As i865 only has the one pipe we want to skip massaging the
plane<->pipe assignment aimed at getting FBC+LVDS working on
the mobile platforms.

5331889b5f drm/i915/fbc: Fix fence_y_offset handling
The current fence_y_offset calculation is broken. I think it more or
less used to do the right thing, but then I changed the plane code
to put the final x/y source offsets back into the src rectangle so
now it's just subtraacting the same value from itself. The code would
never have worked if we allowed the framebuffer to have a non-zero
offset.

Let's do this in a better way by just calculating the fence_y_offset
from the final plane surface offset. Note that we don't align the
plane surface address to fence rows so with horizontal panning there's
often a horizontal offset from the fence start to the surface address
as well. We have no way to tell the hardware about that so we just
ignore it. Based on some quick tests the invlidation still happens
correctly. I presume due to the invalidation nuking at least the full
line (or a segment of multiple lines).

4003dac180 drm/i915: Clamp linetime wm to <64usec
The linetime watermark is a 9 bit value, which gives us
a maximum linetime of just below 64 usec. If the linetime
exceeds that value we currently just discard the high bits
and program the rest into the register, which angers the
state checker.

To avoid that let's just clamp the value to the max. I believe
it should be perfectly fine to program a smaller linetime wm
than strictly required, just means the hardware may fetch data
sooner than strictly needed. We are further reassured by the
fact that with DRRS the spec tells us to program the smaller
of the two linetimes corresponding to the two refresh rates.

8a25c4be58 drm/i915/params: switch to device specific parameters
Start using device specific parameters instead of module parameters for
most things. The module parameters become the immutable initial values
for i915 parameters. The device specific parameters in i915->params
start life as a copy of i915_modparams. Any later changes are only
reflected in the debugfs.

The stragglers are:

* i915.force_probe and i915.modeset. Needed before dev_priv is
  available. This is fine because the parameters are read-only and never
  modified.

* i915.verbose_state_checks. Passing dev_priv to I915_STATE_WARN and
  I915_STATE_WARN_ON would result in massive and ugly churn. This is
  handled by not exposing the parameter via debugfs, and leaving the
  parameter writable in sysfs. This may be fixed up in follow-up work.

* i915.inject_probe_failure. Only makes sense in terms of the module,
  not the device. This is handled by not exposing the parameter via
  debugfs.

af157b7611 drm/i915: Stop using mode->private_flags
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.

cd19154608 drm/i915: Adjust CDCLK accordingly to our DBuf bw needs
According to BSpec max BW per slice is calculated using formula
Max BW = CDCLK * 64. Currently when calculating min CDCLK we
account only per plane requirements, however in order to avoid
FIFO underruns we need to estimate accumulated BW consumed by
all planes(ddb entries basically) residing on that particular
DBuf slice. This will allow us to put CDCLK lower and save power
when we don't need that much bandwidth or gain additional
performance once plane consumption grows.

v2: - Fix long line warning
    - Limited new DBuf bw checks to only gens >= 11

v3: - Lets track used Dbuf bw per slice and per crtc in bw state
      (or may be in DBuf state in future), that way we don't need
      to have all crtcs in state and those only if we detect if
      are actually going to change cdclk, just same way as we
      do with other stuff, i.e intel_atomic_serialize_global_state
      and co. Just as per Ville's paradigm.
    - Made dbuf bw calculation procedure look nicer by introducing
      for_each_dbuf_slice_in_mask - we often will now need to iterate
      slices using mask.
    - According to experimental results CDCLK * 64 accounts for
      overall bandwidth across all dbufs, not per dbuf.

v4: - Fixed missing const(Ville)
    - Removed spurious whitespaces(Ville)
    - Fixed local variable init(reduced scope where not needed)
    - Added some comments about data rate for planar formats
    - Changed struct intel_crtc_bw to intel_dbuf_bw
    - Moved dbuf bw calculation to intel_compute_min_cdclk(Ville)

v5: - Removed unneeded macro

v6: - Prevent too frequent CDCLK switching back and forth:
      Always switch to higher CDCLK when needed to prevent bandwidth
      issues, however don't switch to lower CDCLK earlier than once
      in 30 minutes in order to prevent constant modeset blinking.
      We could of course not switch back at all, however this is
      bad from power consumption point of view.

v7: - Fixed to track cdclk using bw_state, modeset will be now
      triggered only when CDCLK change is really needed.

v8: - Lock global state if bw_state->min_cdclk is changed.
    - Try getting bw_state only if there are crtcs in the commit
      (need to have read-locked global state)

v9: - Do not do Dbuf bw check for gens < 9 - triggers WARN
      as ddb_size is 0.

v10: - Lock global state for older gens as well.

v11: - Define new bw_calc_min_cdclk hook, instead of using
       a condition(Manasi Navare)

v12: - Fixed rebase conflict

v13: - Added spaces after declarations to make checkpatch happy.

4f0b4352bd drm/i915: Extract cdclk requirements checking to separate function
In Gen11+ whenever we might exceed DBuf bandwidth we might need to
recalculate CDCLK which DBuf bandwidth is scaled with.
Total Dbuf bw used might change based on particular plane needs.

Thus to calculate if cdclk needs to be changed it is not enough
anymore to check plane configuration and plane min cdclk, per DBuf
bw can be calculated only after wm/ddb calculation is done and
all required planes are added into the state. In order to keep
all min_cdclk related checks in one place let's extract it into
separate function, checking and modifying any_ms.

c93b9b2c79 drm/i915: Decouple cdclk calculation from modeset checks
We need to calculate cdclk after watermarks/ddb has been calculated
as with recent hw CDCLK needs to be adjusted accordingly to DBuf
requirements, which is not possible with current code organization.

Setting CDCLK according to DBuf BW requirements and not just rejecting
if it doesn't satisfy BW requirements, will allow us to save power when
it is possible and gain additional bandwidth when it's needed - i.e
boosting both our power management and perfomance capabilities.

This patch is preparation for that, first we now extract modeset
calculation from modeset checks, in order to call it after wm/ddb
has been calculated.

v2: - Extract only intel_modeset_calc_cdclk from intel_modeset_checks
      (Ville Syrjälä)

v3: - Clear plls after intel_modeset_calc_cdclk

In general, the plane capabilities of the remaining planes stay the same

planes and now only the bottom three planes can be used for NV12 UV.

5e9e0a3a3b drm/i915: Fix max cursor size for i915g/gm
Apparently the 128x128 and 256x256 ARGB cursor modes were
only added on LPT/CST.

While the display section of bspec isn't super clear on the
subject, it does highlight these two modes in a different
color, has a few changlog entries indicating the 256x256 mode
was added for a LPT DCN, and that the 128x128 mode was also
added later (though no DCN/platform note there).

The "device dependencies" bspec section does list the 256x256x32
as a new feature for LPT/CST, and goes on to mention that current
hw only has the 64x64x32 mode (which reinforces the notion that
the 128x128 mode was also added at the same time).

Testing on actual hardware confirms all of this. CI shows all
the 128x128 and 256x256 tests failing on GDG, and my ALV
definitely doesn't like them.

So we shall limit GDG/ALV to 64x64 only. And while at it
let's adjust the mobile gen2 case to list the two platforms
explicitly so that the if-ladder looks reasonably uniform.

c5a01ec757 drm/i915: Fix skl+ non-scaled pfit modes
Fix skl_update_scaler_crtc() to deal with different scaling
modes correctly. The current implementation assumes
DRM_MODE_SCALE_FULLSCREEN. Fortunately we don't expose any
border properties currently so the code does actually end
up doing the right thing (assigning a scaler for pfit).
The code does need to be fixed before any borders are
exposed.

Also we have redundant calls to skl_update_scaler_crtc() in
dp/hdmi .compute_config() which can be nuked. They were anyway
called before we had even computed the pfit state so were
basically nonsense. The real call we need to keep is in
intel_crtc_atomic_check().

ede9771d7f drm/i915: Pass atomic state to encoder hooks
We're going to want access to the atomic state for iterating
the slave crtcs when enabling the port sync master crtc. Pass
the atomic state all the way down.

The alternative would be yet another encoder hook which we'll
have to call after all the normal modeset stuff is done. Not
really a fan of yet another hook just for this.

Note that during readout state sanitation we are now going
to pass NULL as the atomic state since we don't have one.

we first do the modeset part for every pipe and then do
the plane/etc. updates. Let's follow that apporach for

cb1824bb1e drm/i915: Fix crtc nv12 etc. plane bitmasks for DPMS off
We only consider crtc_state->enable when initially calculating plane
visibility. Later on we try to override the plane's state to invisible
if the crtc is in DPMS off state (crtc_state->active==false).
Unfortunately the code doing that only updates the plane_state.visible
flag and the crtc_state.active_planes bimask, but forgets to update
some of the other plane bitmasks stored in the crtc_state. Namely
crtc_state.nv12_planes is left set up based on the original visibility
check which makes icl_check_nv12_planes() pick a slave plane for the
flagged plane in the bitmask. Later on we hit the watermark code
which sees a plane with a slave assigned and it then makes the
logical assumption that the master plane must itself be visible.
Since the master's plane_state.visible flag was already cleared
we get a WARN.

Fix the problem by clearing all the plane bitmasks for DPMS off.
This is more or less the wrong approach and instead we should
calculate all the plane related state purely based crtc_state->enable
(to guarantee that the subsequent DPMS on can't fail). However in
the past we definitely had some roadblocks to making that happen.
Not sure how many are left these days, but let's stick to the current
approach since it's a much simpler fix to the immediate problem
(the WARN).

v2: Keep the visible=false, it's important (Rodrigo)

2713eb41a1 drm/i915: Distribute switch variables for initialization
Variables declared in a switch statement before any case statements
cannot be automatically initialized with compiler instrumentation (as
they are not part of any execution flow). With GCC's proposed automatic
stack variable initialization feature, this triggers a warning (and they
don't get initialized). Clang's automatic stack variable initialization
(via CONFIG_INIT_STACK_ALL=y) doesn't throw a warning, but it also
doesn't initialize such variables[1]. Note that these warnings (or silent
skipping) happen before the dead-store elimination optimization phase,
so even when the automatic initializations are later elided in favor of
direct initializations, the warnings remain.

To avoid these problems, move such variables into the "case" where
they're used or lift them up into the main function body.

0f8839f5f3 drm/i915: Force state->modeset=true when distrust_bios_wm==true
Currently when we load the driver we set distrust_bios_wm=true, which
will cause active_pipe_changes to get flagged even when we're not
toggling any pipes on/off. The reason being that we want to fully
redistribute the dbuf among the active pipes and ignore whatever
state the firmware left behind.

Unfortunately when the code flags active_pipe_changes it doesn't
set state->modeset to true, which means the hardware dbuf state
won't actually get updated. Hence the hardware and software
states go out of sync, which can result in planes trying to use a
disabled dbuf slice. Suprisingly that only seems to corrupt the
display rather than making the whole display engine keel over.

Let's fix this for now by flagging state->modeset whenever
distrust_bios_wm is set.

Eventually we'll likely want to rip out all of this mess and
introduce proper statye tracking for dbuf. But that requires
more work. Toss in a FIXME to that effect.

We lack full state readout of DSC config, which may lead to DSC enable
using a config that's all zeros, failing spectacularly. Force full
modeset and thus compute config at probe to get a sane state, until we
implement DSC state readout. Any fastset that did appear to work with
DSC at probe, worked by coincidence. [1] is an example of a change that

40d427931d drm/i915: Don't use uninitialized 'ret'
Accidentally removed the 'ret=0' initialization, and thus
we're potentially looking at some stack garbage here.

The whole 'ret = do_stuff; if (!ret) do_other_stuff;' pattern
confuses my brain so let's replace it with the standard
immediate return thing.

c631cc8f11 drm/i915: Make a copy of the ggtt view for slave plane
intel_prepare_plane_fb() will always pin plane_state->hw.fb whenever
it is present. We copy that from the master plane to the slave plane,
but we fail to copy the corresponding ggtt view. Thus when it comes time
to pin the slave plane's fb we use some stale ggtt view left over from
the last time the plane was used as a non-slave plane. If that previous
use involved 90/270 degree rotation or remapping we'll try to shuffle
the pages of the new fb around accordingingly. However the new
fb may be backed by a bo with less pages than what the ggtt view
rotation/remapped info requires, and so we we trip a GEM_BUG().

Steps to reproduce on icl:
1. plane 1: whatever
   plane 6: largish !NV12 fb + 90 degree rotation
2. plane 1: smallish NV12 fb
   plane 6: make invisible so it gets slaved to plane 1
3. GEM_BUG()

0887aa8744 drm/i915: Fix post-fastset modeset check for port sync
The post-fastset "does anyone still need a full modeset?" for
port sync looks busted. The outer loop bails out of a full modeset
is still needed by the current crtc, and then we skip forcing
a full modeset on the related crtcs. That's totally the opposite
of what we want.

The MST path has the logic mostly the other way around so it
looks correct. To fix the port sync case let's follow the MST
logic for both. So, if the current crtc already needs a modeset
we do nothing. otherwise we check if any of the related crtcs
needs a modeset, and if so we force a full modeset for the
current crtc.

And while at let's change the else if to a plain if to so
we don't have needless coupling between the MST and port sync
checks.

0f0f9aeee3 drm/i915: Manipulate DBuf slices properly
Start manipulating DBuf slices as a mask,
but not as a total number, as current approach
doesn't give us full control on all combinations
of slices, which we might need(like enabling S2
only can't enabled by setting enabled_slices=1).

Removed wrong code from intel_get_ddb_size as
it doesn't match to BSpec. For now still just
use DBuf slice until proper algorithm is implemented.

Other minor code refactoring to get prepared
for major DBuf assignment changes landed:
- As now enabled slices contain a mask
  we still need some value which should
  reflect how much DBuf slices are supported
  by the platform, now device info contains
  num_supported_dbuf_slices.
- Removed unneeded assertion as we are now
  manipulating slices in a more proper way.

v2: Start using enabled_slices in dev_priv

v3: "enabled_slices" is now "enabled_dbuf_slices_mask",
    as this now sits in dev_priv independently.

v4: - Fixed debug print formatting to hex(Matt Roper)
    - Optimized dbuf slice updates to be used only
      if slice union is different from current conf(Matt Roper)
    - Fixed some functions to be static(Matt Roper)
    - Created a parameterized version for DBUF_CTL to
      simplify DBuf programming cycle(Matt Roper)
    - Removed unrequred field from GEN10_FEATURES(Matt Roper)

v5: - Removed redundant programming dbuf slices helper(Ville Syrjälä)
    - Started to use parameterized loop for hw readout to get slices
      (Ville Syrjälä)
    - Added back assertion checking amount of DBUF slices enabled
      after DC states 5/6 transition, also added new assertion
      as starting from ICL DMC seems to restore the last DBuf
      power state set, rather than power up all dbuf slices
      as assertion was previously expecting(Ville Syrjälä)

v6: - Now using enum for DBuf slices in this patch (Ville Syrjälä)
    - Removed gen11_assert_dbuf_enabled and put gen9_assert_dbuf_enabled
      back, as we really need to have a single unified assert here
      however currently enabling always slice 1 is enforced by BSpec,
      so we will have to OR enabled slices mask with 1 in order
      to be consistent with BSpec, that way we can unify that
      assertion and against the actual state from the driver, but
      not some hardcoded value.(concluded with Ville)
    - Remove parameterized DBUF_CTL version, to extract it to another
      patch.(Ville Syrjälä)
v7:
    - Removed unneeded hardcoded return value for older gens from
      intel_enabled_dbuf_slices_mask - this now is handled in a
      unified manner since device info anyway returns max dbuf slices
      as 1 for older platforms(Matthew Roper)
    - Now using INTEL_INFO(dev_priv)->num_supported_dbuf_slices instead
      of intel_dbuf_max_slices function as it is trivial(Matthew Roper)

v8: - Fixed icl_dbuf_disable to disable all dbufs still(Ville Syrjälä)

v9: - Renamed _DBUF_CTL_S to DBUF_CTL_S(Ville Syrjälä)
    - Now using power_domain mutex to protect from race condition, which
      can occur because intel_dbuf_slices_update might be running in
      parallel to gen9_dc_off_power_well_enable being called from
      intel_dp_detect for instance, which causes assertion triggered by
      race condition, as gen9_assert_dbuf_enabled might preempt this
      when registers were already updated, while dev_priv was not.

0ef1905ecf drm/i915: Introduce better global state handling
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.

6dcde04706 drm/i915: Move linetime wms into the crtc state
The linetime watermarks really have very little in common with the
plane watermarks. It looks to be cleaner to simply track them in
the crtc_state and program them from the normal modeset/fastset
paths.

The only dark cloud comes from the fact that the register is
still supposedly single buffered. So in theory it might still
need some form of two stage programming. Note that even though
HSW/BDWhave two stage programming we never computed any special
intermediate values for the linetime watermarks, and on SKL+
we don't even have the two stage stuff plugged in since everything
else is double buffered. So let's assume it's all fine and
continue doing what we've been doing.

Actually on HSW/BDW the value should not even change without
a full modeset since it doesn't account for pfit downscaling.
Thus only fastboot might be affected. But on SKL+ the pfit
scaling factor is take into consideration so the value may
change during any fastset.

As a bonus we'll plug this thing into the state
checker/dump now.

v2: Rebase due to bigjoiner prep
v2: Only compute ips linetime for IPS capable pipes.
    Bspec says the register values is ignored for other
    pipes, but in fact it can't even be written so the
    state checker becomes unhappy if we don't compute
    it as zero.

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

d1b2828af0 drm/i915: Fix modeset locks in sanitize_watermarks()
We've added more internal things that use modeset locks and
thus we need to be prepared for intel_atomic_check() grabbing
more locks than what our initial drm_modeset_lock_all_ctx()
took. So we're missing the backoff handling here.

Also drm_atomic_helper_duplicate_state() works against us
by clearing state->acquire_ctx in anticipation of
drm_atomic_helper_commit_duplicated_state() being used to
commit the state.

We could probably just reset acquire_ctx back, but instead
let's just rewrite the whole thing without using either of
those "helpers". There's also no need to add any connectors
to the state here since we just want the new watermarks
which don't depend on connectors.

cb724911f4 drm/i915: Fix inconsistance between pfit.enable and scaler freeing
Despite that during hw readout we seem to have scalers assigned
to pipes, then call atomic_setup_scalers, at the commit stage in
skl_update_scaler there is a check, that if we have fb src and
dest of same size, we stage freeing of that scaler.

However we don't update pfit.enabled flag then, which makes
the state inconsistent, which in turn triggers a WARN_ON
in skl_pfit_enable, because we have pfit enabled,
but no assigned scaler.

To me this looks weird that we kind of do the decision
to use or not use the scaler at skl_update_scaler stage
but not in intel_atomic_setup_scalers, moreover
not updating the whole state consistently.

This fix is to not free the scaler if we have pfit.enabled
flag set, so that the state is now consistent
and the warnings are gone.

v2: - Put pfit.enable check into crtc specific place

c5c772cf8d drm/i915/dc3co: Avoid full modeset when EXITLINE needs to be changed
A recent change in BSpec allow us to change EXTLINE while transcoder
is enabled so this allow us to change it even when doing the first
fastset after taking over previous hardware state set by BIOS.
BIOS don't enable PSR, so if sink supports PSR it will be enabled on
the first fastset, so moving the EXTLINE compute and set to PSR flows
allow us to simplfy a bunch of code.

This will save a lot of time in all the IGT tests that uses CRC, as
when PSR2 is enabled CRCs are not generated, so we switch to PSR1, so
the previous code would compute dc3co_exitline=0 causing a full
modeset that would shutdown pipe, enable and train link.

v2: only programming EXTLINE when DC3CO is enabled

58fa1760d0 drm/i915: Balance prepare_fb/cleanup_fb
intel_prepare_plane_fb() bails early if there is no fb (or rather
no obj, which is the same thing). intel_cleanup_plane_fb() does not.
This means the steps performed by intel_cleanup_plane_fb() aren't
balanced with with what was done intel_prepare_plane_fb() if there
is no fb for the plane. These hooks get called for every plane in
the state regardless of whether they have an fb or not.

Add a matching null obj check to intel_cleanup_plane_fb() to restore
the balance.

Note that intel_cleanup_plane_fb() has sufficient protections
already in place that the imbalance doesn't cause any real problems.
But having things be in balance seems nicer anyway, and might help
avoid some surprises in the future.

plane->state will point to the uapi state which we generally don't

Also it sets a bad example as using plane->state during commit_tail()

fff13e63a1 drm/i915: Clear most of crtc state when disabling the crtc
Currently we don't call intel_crtc_prepare_cleared_state() for crtcs
that are going to be entirely disabled (uapi.enable==false). That
means such crtcs will leave stale junk lying around in their states
and we have to sprinkle hw.enable checks all over before we can
look at the states. Let's change that a bit so that we aways do
the state clearing, even for fully disabled crtcs.

Note that we still keep some parts of the old state (see
intel_crtc_prepare_cleared_state() for the details) so probably
can't trust things 100% when hw.enable==false. But at least there's
less chance now that we end up looking at stale junk.

d0eed1545f drm/i915: Fix post-fastset modeset check for port sync
The post-fastset "does anyone still need a full modeset?" for
port sync looks busted. The outer loop bails out of a full modeset
is still needed by the current crtc, and then we skip forcing
a full modeset on the related crtcs. That's totally the opposite
of what we want.

The MST path has the logic mostly the other way around so it
looks correct. To fix the port sync case let's follow the MST
logic for both. So, if the current crtc already needs a modeset
we do nothing. otherwise we check if any of the related crtcs
needs a modeset, and if so we force a full modeset for the
current crtc.

And while at let's change the else if to a plain if to so
we don't have needless coupling between the MST and port sync
checks.

103605e0d1 drm/i915: Make a copy of the ggtt view for slave plane
intel_prepare_plane_fb() will always pin plane_state->hw.fb whenever
it is present. We copy that from the master plane to the slave plane,
but we fail to copy the corresponding ggtt view. Thus when it comes time
to pin the slave plane's fb we use some stale ggtt view left over from
the last time the plane was used as a non-slave plane. If that previous
use involved 90/270 degree rotation or remapping we'll try to shuffle
the pages of the new fb around accordingingly. However the new
fb may be backed by a bo with less pages than what the ggtt view
rotation/remapped info requires, and so we we trip a GEM_BUG().

Steps to reproduce on icl:
1. plane 1: whatever
   plane 6: largish !NV12 fb + 90 degree rotation
2. plane 1: smallish NV12 fb
   plane 6: make invisible so it gets slaved to plane 1

05a8e45136 drm/i915/display: Use external dependency loop for port sync
This loop was added directly to intel_atomic_check() to be used by
all other features that have external pipe dependencies, so using it
and removing intel_atomic_check_synced_crtcs().

After this changes is_trans_port_sync_master() it not used anywhere,
so removing it.

2dfbf9d287 drm/i915/tgl: Gen-12 display can decompress surfaces compressed by the media engine
Detect the modifier corresponding to media compression to enable
display decompression for YUV and xRGB packed formats. A new modifier is
added so that the driver can distinguish between media and render
compressed buffers. Unlike render decompression, plane 6 and  plane 7 do not
support media decompression.

v2: Fix checkpatch warnings on code style (Lucas)

From DK:
Separate modifier array for planes that cannot decompress media (Ville)

v3: Support planar formats
v4: Switch plane order
v5:
- Use format block descriptors to get CCS subsampling calculation right
  everywhere.
- Extend the plane state normal view array to accommodate 4 color planes.
- Use helpers to convert between main and CCS planes.
v6: Add missing packed YUV formats to the MC format list. (Yang)
v7: Align UV planes to tile-row size.

d156135e6a drm/i915/tgl: Make sure a semiplanar UV plane is tile row size aligned
Currently the GGTT offset of a UV plane in a semiplanar YUV FB is tile
size (4kB) aligned. I noticed, that enforcing only this alignment leads
oddly to random memory corruptions on TGL while scanning out Y-tiled
FBs. This issue can be easily reproduced with a UV plane offset that is
not aligned to the plane's tile row size.

Some experiments showed the correct alignment to be tile row size
indeed. This also makes sense, since the de-tiling fence created for the
object - with its own stride and so "left" and "right" edge - applies to
all the planes in the FB, so each tile row of all planes should be tile
row aligned.

In fact BSpec requires this alignment since SKL. On SKL we may enforce
this due to the AUX plane x,y coords check, but on ICL and TGL we don't.
For now enforce this only on TGL; I can follow up with any necessary
change for ICL after more tests.

BSpec requires a stricter alignment for linear UV planes too (kind of a
tile row alignment), but it's unclear whether that's really needed
(couldn't be explained with the de-tiling fence as above) and enforcing
that could break existing user space; so avoid that too for now until
more tests.

v2:
- Clarify the commit log wrt. the address space the alignment applies to.
  (Chris)

7361bdb26c drm/i915: Add support for non-power-of-2 FB plane alignment
At least one framebuffer plane on TGL - the UV plane of YUV semiplanar
FBs - requires a non-power-of-2 alignment, so add support for this. This
new alignment restriction applies only to an offset within an FB, so the
GEM buffer itself containing the FB must still be power-of-2 aligned.
Add a check for this (in practice plane 0, since the plane 0 offset must
be 0).

v2:
- Fix WARN check for alignment=0.
v3:
- Return error for alignment programming bugs. (Chris)

a603f5bd16 drm/i915/dp: Make sure all tiled connectors get added to the state with full modeset
In case of tiled displays, all the tiles are linke dto each other
for transcoder port sync. So in intel_atomic_check() we need to make
sure that we add all the tiles to the modeset and if one of the
tiles needs a full modeset then mark all other tiles for a full modeset.

We also need to force modeset for all synced crtcs after fastset check.

v6:

* Add FIXME for a corner case where tile info might vanish (Matt)
v5:
* Rebase
v4:

659f14158f drm/i915/display: Always enables MST master pipe first
Due to DDB overlaps the pipe enabling sequence is not always crescent.
As the previous patch selects the smallest pipe/transcoder in the MST
stream to be master and it needs to be enabled first, this changes
were needed to guarantee that.

So first lets enable all pipes that do not need a fullmodeset as
those don't have any external dependency and those are the ones that
can overlap with each other.

Then on the second loop it will enable all the pipes that needs a
modeset and don't depends on other pipes like MST master
pipe/transcoder.

Then finally all the pipes that needs a modeset and have dependency
on other pipes, that at this point are alread enabled.

v3: rebased

v4:
- added check for modeset_pipes too to decide if is necessary for a
wait a vblank
- added DDB allocation overlap check for pipes that needs a modeset

6671c367a9 drm/i915/tgl: Select master transcoder for MST stream
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

v4:

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:

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.

Remove the pointless vfunc detour for hsw_fdi_link_train()
and just call it directly. Also pass the encoder in so we
can nuke the silly encoder loop within.

979e94c1d6 drm/i915: Introduce intel_crtc_state_reset()
We have a few places where we want to reset a crtc state to its
default values. Let's add a helper for that. We'll need the new
__drm_atomic_helper_crtc_state_reset() helper for this to allow
us to just reset the state itself without clobbering the
crtc->state pointer.

And while at it let's zero out the whole thing, except a few
choice member which we'll mark as "invalid". And thanks to this
we can now nuke intel_crtc_init_scalers().

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

cfdd174798 drm/i915: Make intel_crtc_arm_fifo_underrun() functional on gen2
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
hw_done/flip_done waits in place.

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.

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.

Make sure we have a crtc before probing its primary plane's

Not sure if we shouldn't disable dumb buffer support entirely

1e460bf9ea drm/i915: Frob the correct crtc state in intel_crtc_disable_noatomic()
The uapi vs. hw state split introduced a bug in
intel_crtc_disable_noatomic() where it's now frobbing an already
freed temp crtc state instead of adjusting the crtc state we
are really left with. Fix that by making a cleaner separation
beteen the two.

This causes explosions on any machine that boots up with pipes
already running but not hooked up to any encoder (typical
behaviour for gen2-4 VBIOS).

Splitting plane state is easier than splitting crtc_state,

We copy the state after we did all the modeset handling, but fortunately
i915 seems to be split correctly and nothing during modeset looks
at plane_state.

f9d9fece29 drm/i915/display: Mark conn as initialised by iterator
smatch complains about
drivers/gpu/drm/i915//display/intel_display.c:14403 intel_set_dp_tp_ctl_normal() error: uninitialized symbol 'conn'.
because it has no way to determine that the loop must have an entry.
Tell the static analysers to ignore the local, it will always be set.

3e7abf8141 drm/i915: Extract GT render power state management
i915_irq.c is large. One reason for this is that has a large chunk of
the GT render power management stashed away in it. Extract that logic
out of i915_irq.c and intel_pm.c and put it under one roof.

Based on a patch by Chris Wilson.

dd5279c714 drm/i915: Fix PCH reference clock for FDI on HSW/BDW
The change to skip the PCH reference initialization during fastboot
did end up breaking FDI. To fix that let's try to do the PCH reference
init whenever we're disabling a DPLL that was using said reference
previously.
