Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
Since we try and estimate how long we require to update the registers to
perform a plane update, it is of vital importance that we measure the
distribution of plane updates to better guide our estimate. If we
underestimate how long it takes to perform the plane update, we may
slip into the next scanout frame causing a tear. If we overestimate, we
may unnecessarily delay the update to the next frame, causing visible
jitter.
Replace the warning that we exceed some arbitrary threshold for the
vblank update with a histogram for debugfs.
v2: Add a per-crtc debugfs entry so that the information is easier to
extract when testing individual CRTC, and so that it can be reset before
a test.
v3: Flip the graph on its side; creates space to label the time axis.

For DG1 we have a little of mix up wrt to DDI/port names and indexes.
Bspec refers to the ports as DDIA, DDIB, DDI USBC1 and DDI USBC2
(besides the DDIA, DDIB, DDIC, DDID), but the previous naming is the
most unambiguous one. This means that for any register on Display Engine
we should use the index of A, B, D and E. However in some places this is
not true:
- VBT: uses C and D and have to be mapped to D/E
- IO/Combo: uses C and D, but we already differentiate those when
we created the phy vs port distinction.
This additional mapping for VBT and phy are already covered in previous
patches, so now we can initialize all the DDIs as A, B, D and E.
v2: Squash previous patch enabling just ports A and B since most of the
pumbling code is already merged now

EDID can declare the maximum supported bpc up to 16,
and apparently there are displays that do so. Currently
we assume 12 bpc is tha max. Fix the assumption and
toss in a MISSING_CASE() for any other value we don't
expect to see.
This fixes modesets with a display with EDID max bpc > 12.
Previously any modeset would just silently fail on platforms
that didn't otherwise limit this via the max_bpc property.
In particular we don't add the max_bpc property to HDMI
ports on gmch platforms, and thus we would see the raw
max_bpc coming from the EDID.
I suppose we could already adjust this to also allow 16bpc,
but seeing as no current platform supports that there is

When using bigjoiner userspace is only controlling the "master"
plane, so use its uapi state for the "slave" plane as well.
hw.crtc needs a bit of magic since we don't want to copy that from
the uapi state (as it points to the wrong pipe for the "slave
" plane). Instead we pass the right crtc in explicitly but only
assign it when the uapi state indicates the plane to be logically
enabled (ie. uapi.crtc != NULL).

This way ideally everything will be tear free, and updates are

Integer scaling (IS) is a nearest-neighbor upscaling technique that
simply scales up the existing pixels by an integer
(i.e., whole number) multiplier.Nearest-neighbor (NN) interpolation
works by filling in the missing color values in the upscaled image
with that of the coordinate-mapped nearest source pixel value.
Both IS and NN preserve the clarity of the original image. Integer
scaling is particularly useful for pixel art games that rely on
sharp, blocky images to deliver their distinctive look.
Introduce functions to configure the scaler filter coefficients to
enable nearest-neighbor filtering.

Currently we call .hpd_irq_setup() directly just before display
resume, and follow it with another call via intel_hpd_init()
just afterwards. Assuming the hpd pins are marked as enabled
during the open-coded call these two things do exactly the
same thing (ie. enable HPD interrupts). Which even makes sense
since we definitely need working HPD interrupts for MST sideband
during the display resume.
So let's nuke the open-coded call and move the intel_hpd_init()
call earlier. However we need to leave the poll_init_work stuff
behind after the display resume as that will trigger display
detection while we're resuming. We don't want that trampling over
the display resume process. To make this a bit more symmetric
we turn this into a intel_hpd_poll_{enable,disable}() pair.
So we end up with the following transformation:
intel_hpd_poll_init() -> intel_hpd_poll_enable()
lone intel_hpd_init() -> intel_hpd_init()+intel_hpd_poll_disable()
.hpd_irq_setup()+resume+intel_hpd_init() -> intel_hpd_init()+resume+intel_hpd_poll_disable()
If we really would like to prevent all *long* HPD processing during
display resume we'd need some kind of software mechanism to simply
ignore all long HPDs. Currently we appear to have that just for
fbdev via ifbdev->hpd_suspended. Since we aren't exploding left and
right all the time I guess that's mostly sufficient.
For a bit of history on this, we first got a mechanism to block
hotplug processing during suspend in commit 15239099d7 ("drm/i915:
enable irqs earlier when resuming") on account of moving the irq enable
earlier. This then got removed in commit 50c3dc970a ("drm/fb-helper:
Fix hpd vs. initial config races") because the fdev initial config
got pushed to a later point. The second ad-hoc hpd_irq_setup() for
resume was added in commit 0e32b39cee ("drm/i915: add DP 1.2 MST
support (v0.7)") to be able to do MST sideband during the resume.
And finally we got a partial resurrection of the hpd blocking
mechanism in commit e8a8fedd57 ("drm/i915: Block fbdev HPD
processing during suspend"), but this time it only prevent fbdev
from handling hpd while resuming.

Currently we leave the cache_level of the initial fb obj
set to NONE. This means on eLLC machines the first pin_to_display()
will try to switch it to WT which requires a vma unbind+bind.
If that happens during the fbdev initialization rcu does not
seem operational which causes the unbind to get stuck. To
most appearances this looks like a dead machine on boot.
Avoid the unbind by already marking the object cache_level
as WT when creating it. We still do an excplicit ggtt pin
which will rewrite the PTEs anyway, so they will match whatever

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.

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.

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.

wouldnt have the udpated vblank counter yet. This will lead to a state

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.

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.

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

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)

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.

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).

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.

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.

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.

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.

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.

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)

RKL only has five universal planes, plus a cursor. Since the
bottom-most universal plane is considered the primary plane, set the
number of sprites available on this platform to 4.
In general, the plane capabilities of the remaining planes stay the same
as TGL. However the NV12 Y-plane support moves down to the new top two
planes and now only the bottom three planes can be used for NV12 UV.

Encapsulate the dbuf state more by moving the pre/post
plane functions out from intel_display.c. We stick them
into intel_pm.c since that's where the rest of the code
lives for now.
Eventually we should add a new file for this stuff at which

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.

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().

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).

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.

We have to write quite a few registers when programming the
pipe scaler. Let's use intel_de_write_fw() for these to reduce
the lockdep overhead a bit. All plane registers (including plane
scaler) already do this.
We already had a few accidental intel_de_write_fw() in there.

This patch pushes out the computation of master and slave

This ensures that the assigned master slave crtcs have exact same

Add an optional secondary encoder state compute hook. This gets
called after the normak .compute_config() has been called for
all the encoders in the state. Thus in the new hook we can rely
on all derived state populated by .compute_config() to be already
set up. Should be useful for MST and port sync master/slave
transcoder selection.

Split intel_modeset_driver_remove() to two, the part with working irqs
