1b38cf6b03 drm/nouveau/kms/nv50-: Lookup current encoder/crtc from atomic state
Despite being an atomic driver, nouveau has a lot of leftover code that
relies on retrieving information regarding the new atomic state from
members of drm_encoder and drm_crtc. The first field being used,
drm_encoder.crtc, is deprecated for atomic drivers. The second field being
used is drm_crtc.state, which is only really sensible to use outside of an
atomic modeset.

So, add some helpers to lookup the current crtc for a given outp from the
atomic state. Then, convert most of the code in dispnv50/disp.c to use said
new helper, along with the relevant DRM atomic helpers for retrieving the
new encoder/crtc combinations for a new atomic state.

Note that we don't get rid of the nouveau_encoder.crtc field entirely for
three reasons:

- Legacy modesetting for pre-nv50 still uses it
- It doesn't cause any locking issues
- We need it for the HDA callbacks, as grabbing atomic modesetting locks in
  those would be a mess.

f60f8705fc drm/nouveau/kms/nv50-: s/armh/asyh/ in nv50_msto_atomic_enable()
I have a strange dejavu feeling that I tried to submit a patch for this in
the past, but that it was rejected. I can't remember though, but I'm
further convinced this patch is the right thing to do anyway.

We label the to-be-committed head state in nv50_msto_atomic_enable() as
armh. Normally armh implies a state which is currently armed in hardware.
nv50_msto_atomic_enable() is called _after_ drm_atomic_swap_state()
however, but before the commit tail ends, which means that said state is
not actually armed on hardware.

As well - take note that this is the same convention followed in all of the
other atomic_enable() callbacks.

So, let's correct this to asyh.

f575f2bdb6 drm/nouveau/kms/nv50-: Remove (nv_encoder->crtc) checks in ->disable callbacks
Noticed these in both the disable (which we'll be getting rid of in a
moment) and the atomic disable callbacks: both callback types check whether
or not there's actually a CRTC assigned to the given encoder. However, as
->atomic_disable and ->disable will never be called without a CRTC assigned
to the given encoder there's no point in this check. So just remove it.

f2fcb0692d drm/nouveau/fifo/tu102: Turing channel preemption fix
Previous hardware allowed a MMU fault to be generated by software to
trigger a context switch for engine recovery. Turing has the capability
to preempt all work from a specific runlist processor and removed the
registers currently used for triggering MMU faults. Attempting to access
these non-existent registers results in further errors, so use the
runlist preemption register instead.

b59c27cab2 drm/i915: Fix the MST PBN divider calculation
Atm the driver will calculate a wrong MST timeslots/MTP (aka time unit)
value for MST streams if the link parameters (link rate or lane count)
are limited in a way independent of the sink capabilities (reported by
DPCD).

One example of such a limitation is when a MUX between the sink and
source connects only a limited number of lanes to the display and
connects the rest of the lanes to other peripherals (USB).

Another issue is that atm MST core calculates the divider based on the
backwards compatible DPCD (at address 0x0000) vs. the extended
capability info (at address 0x2200). This can result in leaving some
part of the MST BW unused (For instance in case of the WD19TB dock).

Fix the above two issues by calculating the PBN divider value based on
the rate and lane count link parameters that the driver uses for all
other computation.

The HDCP 1.4 spec does not require the QUERY_STREAM_ENCRYPTION_STATUS
check, it was always a nice-to-have. After deploying this across various
devices, we've determined that some MST bridge chips do not properly
support this call for HDCP 1.4 (namely Synaptics and Realtek).

I had considered creating a quirk for this, but I think it's more
prudent to just disable the check entirely since I don't have an idea
how widespread support is.

fed3875720 drm/i915/display: Prevent double YUV range correction on HDR planes
Prevent the ICL HDR plane pipeline from performing YUV color range
correction twice when the input is in limited range. This is done by
removing the limited-range code from icl_program_input_csc().

Before this patch the following could happen: user space gives us a YUV
buffer in limited range; per the pipeline in [1], the plane would first
go through a "YUV Range correct" stage that expands the range; the plane
would then go through the "Input CSC" stage which would also expand the
range because icl_program_input_csc() would use a matrix and an offset
that assume limited-range input; this would ultimately cause dark and
light colors to appear darker and lighter than they should respectively.

This is an issue because if a buffer switches between being scanned out
and being composited with the GPU, the user will see a color difference.
If this switching happens quickly and frequently, the user will perceive
this as a flickering.

ef79d62b5c drm/i915: Encapsulate dbuf state handling harder
In order to make the dbuf state computation less fragile
let's make it stand on its own feet by not requiring someone
to peek into a crystall ball ahead of time to figure out
which pipes need to be added to the state under which potential
future conditions. Instead we compute each piece of the state
as we go along, and if any fallout occurs that affects more than
the current set of pipes we add the affected pipes to the state
naturally.

That requires that we track a few extra thigns in the global
dbuf state: dbuf slices for each pipe, and the weight each
pipe has when distributing the same set of slice(s) between
multiple pipes. Easy enough.

We do need to follow a somewhat careful sequence of computations
though as there are several steps involved in cooking up the dbuf
state. Thoguh we could avoid some of that by computing more things
on demand instead of relying on earlier step of the algorithm to
have filled it out. I think the end result is still reasonable
as the entire sequence is pretty much consolidated into a single
function instead of being spread around all over.

The rough sequence is this:
1. calculate active_pipes
2. calculate dbuf slices for every pipe
3. calculate total enabled slices
4. calculate new dbuf weights for any crtc in the state
5. calculate new ddb entry for every pipe based on the sets of
   slices and weights, and add any affected crtc to the state
6. calculate new plane ddb entries for all crtcs in the state,
   and add any affected plane to the state so that we'll perform
   the requisite hw reprogramming

And as a nice bonus we get to throw dev_priv->wm.distrust_bios_wm
out the window.

47a1495510 drm/i915: Add pipe ddb entries into the dbuf state
The dbuf state will be where we collect all the inter-pipe dbuf
allocation stuff. Start by adding the actual per-pipe ddb entries
there.

Originally the plan was to move them there outright, but that no longer
works as we're no longer guaranteed to have a dbuf state when it comes
time to sanity check the ddb overlaps in skl_commit_modeset_enables().
I think when I wrote this originally we did the watermark/ddb
calculation last, and so we couldn't have any crtcs in the state w/o
also having the dbuf state. But that has since changed and we do the
watermark/ddb calculation much earlier, and thus it is now possible
to commit crtcs w/o a dbuf state. So we keep another copy of the
information in the crtc state.

7a2ec4a0a5 drm/i915: Fix vblank timestamps with VRR
To get sensible vblank timestamping behaviour we need to feed
the vmax based timings to the vblank code, otherwise it'll chop
off the scanline counter when it exceeds the minumum vtotal.

Additionally with VRR we have three cases to consider when we
generate the vblank timestamp:
1) we are in vertical active
  -> nothing special needs to be done, just return the current
     scanout position and the core will calculate the timestamp
     corresponding to the past time when the current vertical
     active started
2) we are in vertical blank and no push has been sent
  -> the hardware will keep extending the vblank presumably
     to its maximum length, so we make the timestmap match the
     expected time when the max length vblank will end. Since
     the timings used for this are now based on vmax nothing
     special actually needs to be done
3) we are in vblank and a push has been sent so the vblank is
   about to terminate
  -> presumably we want the timestmap to accurately reflect
     when the vblank will terminate, so we use the sampled
     frame timestamp vs. current timestamp to guesstimate
     how far along the vblank exit we are, and then we
     adjust the reported scanout position accordingly so
     that the core will see that the vblank is close to
     ending.

efa18405ba drm/amd/display: Fix HDMI deep color output for DCE 6-11.
This fixes corrupted display output in HDMI deep color
10/12 bpc mode at least as observed on AMD Mullins, DCE-8.3.

It will hopefully also provide fixes for other DCE's up to
DCE-11, assuming those will need similar fixes, but i could
not test that for HDMI due to lack of suitable hw, so viewer
discretion is advised.

dce110_stream_encoder_hdmi_set_stream_attribute() is used for
HDMI setup on all DCE's and is missing color_depth assignment.

dce110_program_pix_clk() is used for pixel clock setup on HDMI
for DCE 6-11, and is missing color_depth assignment.

Additionally some of the underlying Atombios specific encoder
and pixelclock setup functions are missing code which is in
the classic amdgpu kms modesetting path and the in the radeon
kms driver for DCE6/DCE8.

encoder_control_digx_v3() - Was missing setup code wrt. amdgpu
and radeon kms classic drivers. Added here, but untested due to
lack of suitable test hw.

encoder_control_digx_v4() - Added missing setup code.
Successfully tested on AMD mullins / DCE-8.3 with HDMI deep color
output at 10 bpc and 12 bpc.

Note that encoder_control_digx_v5() has proper setup code in place
and is used, e.g., by DCE-11.2, but this code wasn't used for deep
color setup due to the missing cntl.color_depth setup in the calling
function for HDMI.

set_pixel_clock_v5() - Missing setup code wrt. classic amdgpu/radeon
kms. Added here, but untested due to lack of hw.

set_pixel_clock_v6() - Missing setup code added. Successfully tested
on AMD mullins DCE-8.3. This fixes corrupted display output at HDMI
deep color output with 10 bpc or 12 bpc.

1916866dfa drm/amd/display: Fix 10/12 bpc setup in DCE output bit depth reduction.
In set_clamp(), the comments and definitions for the COLOR_DEPTH_101010
and COLOR_DEPTH_121212 cases directly contradict the code comment which
explains how this should work, whereas the COLOR_DEPTH_888 case
is consistent with the code comments. Comment says the bitmask should
be chosen to align to the top-most 10 or 12 MSB's on a 14 bit bus, but
the implementation contradicts that: 10 bit case sets a mask for 12 bpc
clamping, whereas 12 bit case sets a mask for 14 bpc clamping.

Note that during my limited testing on DCE-8.3 (HDMI deep color)
and DCE-11.2 (DP deep color), this didn't have any obvious ill
effects, neither did fixing it change anything obvious for the
better, so this fix may be inconsequential on DCE, and just
reduce the confusion of innocent bystanders when reading the code
and trying to investigate problems with 10 bpc+ output.

d1e2775e9b drm/i915/tgl: Add Clear Color support for TGL Render Decompression
Render Decompression is supported with Y-Tiled main surface. The CCS is
linear and has 4 bits of data for each main surface cache line pair, a
ratio of 1:256. Additional Clear Color information is passed from the
user-space through an offset in the GEM BO. Add a new modifier to identify
and parse new Clear Color information and extend Gen12 render decompression
functionality to the newly added modifier.

v2: Fix has_alpha flag for modifiers, omit CC modifier during initial
    plane config(Matt). Fix Lookup error.
v3: Fix the panic while running kms_cube
v4: Add alignment check and reuse the comments for ge12_ccs_formats(Matt)
v5: Fix typos and wrap comments(Matt)
v6:
- Use format block descriptors to get the subsampling calculations for
  the CCS surface right.
- Use helpers to convert between main and CCS surfaces.
- Prevent coordinate checks for the CC surface.
- Simplify reading CC value from surface map, add description of CC val
  layout.
- Remove redundant ccval variable from skl_program_plane().
v7:
- Move the CC value readout after syncing against any GPU write on the
  FB obj (Nanley, Chris)
- Make sure the CC value readout works on platforms w/o struct pages
  (dGFX) and other non-coherent platforms wrt. CPU reads (none atm).
  (Chris)
v8:
- Rebase on the function param order change of
  i915_gem_object_read_from_page().
- Clarify code comment on the clear color value format and the required
  FB obj pinning/syncing by the caller.
- Remove redundant variables in
  intel_atomic_prepare_plane_clear_colors().
v9:
- Fix s/sizeof(&ccval)/sizeof(ccval)/ typo.

5fbc2c2bfa drm/i915/gem: Add a helper to read data from a GEM object page
Add a simple helper to read data with the CPU from the page of a GEM
object. Do the read either via a kmap if the object has struct pages
or an iomap otherwise. This is needed by the next patch, reading a u64
value from the object (w/o requiring the obj to be mapped to the GPU).

Suggested by Chris.

v2 (Chris):
- Sanitize the type and order of func params.
- Avoid consts requiring too many casts.
- Use BUG_ON instead of WARN_ON, simplify the conditions.
- Fix __iomem sparse errors.
- Leave locking/syncing/pinning up to the caller, require only that the
  caller has pinned the object pages.
- Check for iomem backing store before reading via an iomap.
v3:
- Fix offset passed to io_mapping_map_wc() missing a mem.region.start
  delta. (Chris, Matthew)

fe7d52bcca drm/i915/dp: Don't use DPCD backlights that need PWM enable/disable
We haven't yet implemented support for backlights that need to be
enabled/disabled via PWM instead of AUX, which means we'll break things if
we enable DPCD backlight control on these machines. Luckily though since
most of these machines work fine just using the plain PWM backlight
controls anyway, there shouldn't be any issue with just leaving DPCD
backlight controls disabled in such situations.

This should fix the issues with PWM being left on that were being observed
on fi-bdw-samus.

a089301d8d drm/msm/dp: fix build after dp quirk helper change
Commit 7c553f8b5a ("drm/dp: Revert "drm/dp: Introduce EDID-based
quirks"") removed drm_dp_get_edid_quirks() and changed the signature of
drm_dp_has_quirk() while they were still being used in msm. Fix the
breakage. Functionally, removing the EDID-based quirks has no impact on
msm.

[The above commit was merged to drm-intel-next; make two wrongs a right
by merging this fix through drm-intel-next as well.]

In the shrinker, we protect framebuffers from light reclaim as we

low latency requirements). We can apply the same logic to the GGTT
eviction and defer framebuffers to the second pass only used if the
caller is desperate enough to wait for space to become available.
In most cases, the caller will use a smaller partial vma instead of
trying to force the object into the GGTT if doing so will cause other

singlethreaded suspend, no one will observe the imposed latency and we
can opt for the faster wbinvd to clear all objects in a single hit.

There is a module parameter for controlling what GuC/HuC features are
enabled. Setting to -1 means 'use the default'. However, the default
was not well defined, out of date and needs to be different across
platforms.

The default is now to disable both GuC and HuC on legacy platforms
where legacy means TGL/RKL and anything prior to Gen12. For new
platforms, the default is to load HuC but not enable GuC submission
as that has not landed yet.

e7004ea4f5 drm/i915/gt: Close race between enable_breadcrumbs and cancel_breadcrumbs
If we enable_breadcrumbs for a request while that request is being
removed from HW; we may see that the request is active as we take the
ce->signal_lock and proceed to attach the request to ce->signals.
However, during unsubmission after marking the request as inactive, we
see that the request has not yet been added to ce->signals and so skip
the removal. Pull the check during cancel_breadcrumbs under the same
spinlock as enabling so that we the two tests are consistent in
enable/cancel.

Otherwise, we may insert a request onto ce->signals that we expect should
not be there:

  intel_context_remove_breadcrumbs:488 GEM_BUG_ON(!__i915_request_is_complete(rq))

While updating, we can note that we are always called with
irqs-disabled, due to the engine->active.lock being held at the single
caller, and so remove the irqsave/restore making it symmetric to
enable_breadcrumbs.

7c553f8b5a drm/dp: Revert "drm/dp: Introduce EDID-based quirks"
This reverts commit 0883ce8146. Originally
these quirks were added because of the issues with using the eDP
backlight interfaces on certain laptop panels, which made it impossible
to properly probe for DPCD backlight support without having a whitelist
for panels that we know have working VESA backlight control interfaces
over DPCD. As well, it should be noted it was impossible to use the
normal sink OUI for recognizing these panels as none of them actually
filled out their OUIs, hence needing to resort to checking EDIDs.

At the time we weren't really sure why certain panels had issues with
DPCD backlight controls, but we eventually figured out that there was a
second interface that these problematic laptop panels actually did work
with and advertise properly: Intel's proprietary backlight interface for
HDR panels. So far the testing we've done hasn't brought any panels to
light that advertise this interface and don't support it properly, which
means we finally have a real solution to this problem.

As a result, we now have no need for the force DPCD backlight quirk, and
furthermore this also removes the need for any kind of EDID quirk
checking in DRM. So, let's just revert it for now since we were the only
driver using this.

2227816e64 drm/i915/dp: Allow forcing specific interfaces through enable_dpcd_backlight
Since we now support controlling panel backlights through DPCD using
both the standard VESA interface, and Intel's proprietary HDR backlight
interface, we should allow the user to be able to explicitly choose
between one or the other in the event that we're wrong about panels
reliably reporting support for the Intel HDR interface.

So, this commit adds support for this by introducing two new
enable_dpcd_backlight options: 2 which forces i915 to only probe for the
VESA interface, and 3 which forces i915 to only probe for the Intel
backlight interface (might be useful if we find panels in the wild that
report the VESA interface in their VBT, but actually only support the
Intel backlight interface).

4a8d79901d drm/i915/dp: Enable Intel's HDR backlight interface (only SDR for now)
So-recently a bunch of laptops on the market have started using DPCD
backlight controls instead of the traditional DDI backlight controls.
Originally we thought we had this handled by adding VESA backlight
control support to i915, but the story ended up being a lot more
complicated then that.

Simply put-there's two main backlight interfaces Intel can see in the
wild. Intel's proprietary HDR backlight interface, and the standard VESA
backlight interface. Note that many panels have been observed to report
support for both backlight interfaces, but testing has shown far more
panels work with the Intel HDR backlight interface at the moment.
Additionally, the VBT appears to be capable of reporting support for the
VESA backlight interface but not the Intel HDR interface which needs to
be probed by setting the right magic OUI.

On top of that however, there's also actually two different variants of
the Intel HDR backlight interface. The first uses the AUX channel for
controlling the brightness of the screen in both SDR and HDR mode, and
the second only uses the AUX channel for setting the brightness level in
HDR mode - relying on PWM for setting the brightness level in SDR mode.

For the time being we've been using EDIDs to maintain a list of quirks
for panels that safely do support the VESA backlight interface. Adding
support for Intel's HDR backlight interface in addition however, should
finally allow us to auto-detect eDP backlight controls properly so long
as we probe like so:

* If the panel's VBT reports VESA backlight support, assume it really
  does support it
* If the panel's VBT reports DDI backlight controls:
  * First probe for Intel's HDR backlight interface
  * If that fails, probe for VESA's backlight interface
  * If that fails, assume no DPCD backlight control
* If the panel's VBT reports any other backlight type: just assume it
  doesn't have DPCD backlight controls

Changes since v4:
* Fix checkpatch issues
Changes since v3:
* Stop using drm_device and use drm_i915_private instead
* Don't forget to return from intel_dp_aux_hdr_get_backlight() if we fail
  to read the current backlight mode from the DPCD
* s/uint8_t/u8/
* Remove unneeded parenthesis in intel_dp_aux_hdr_enable_backlight()
* Use drm_dbg_kms() in intel_dp_aux_init_backlight_funcs()

a575c00e5b drm/i915: Keep track of pwm-related backlight hooks separately
Currently, every different type of backlight hook that i915 supports is
pretty straight forward - you have a backlight, probably through PWM
(but maybe DPCD), with a single set of platform-specific hooks that are
used for controlling it.

HDR backlights, in particular VESA and Intel's HDR backlight
implementations, can end up being more complicated. With Intel's
proprietary interface, HDR backlight controls always run through the
DPCD. When the backlight is in SDR backlight mode however, the driver
may need to bypass the TCON and control the backlight directly through
PWM.

So, in order to support this we'll need to split our backlight callbacks
into two groups: a set of high-level backlight control callbacks in
intel_panel, and an additional set of pwm-specific backlight control
callbacks. This also implies a functional changes for how these
callbacks are used:

* We now keep track of two separate backlight level ranges, one for the
  high-level backlight, and one for the pwm backlight range
* We also keep track of backlight enablement and PWM backlight
  enablement separately
* Since the currently set backlight level might not be the same as the
  currently programmed PWM backlight level, we stop setting
  panel->backlight.level with the currently programmed PWM backlight
  level in panel->backlight.pwm_funcs->setup(). Instead, we rely
  on the higher level backlight control functions to retrieve the
  current PWM backlight level (in this case, intel_pwm_get_backlight()).
  Note that there are still a few PWM backlight setup callbacks that
  do actually need to retrieve the current PWM backlight level, although
  we no longer save this value in panel->backlight.level like before.

Additionally, we drop the call to lpt_get_backlight() in
lpt_setup_backlight(), and avoid unconditionally writing the PWM value that
we get from it and only write it back if we're in CPU mode, and switching
to PCH mode. The reason for this is because in the original codepath for
this, it was expected that the intel_panel_bl_funcs->setup() hook would be
responsible for fetching the initial backlight level. On lpt systems, the
only time we could ever be in PCH backlight mode is during the initial
driver load - meaning that outside of the setup() hook, lpt_get_backlight()
will always be the callback used for retrieving the current backlight
level. After this patch we still need to fetch and write-back the PCH
backlight value if we're switching from CPU mode to PCH, but because
intel_pwm_setup_backlight() will retrieve the backlight level after setup()
using the get() hook, which always ends up being lpt_get_backlight(). Thus
- an additional call to lpt_get_backlight() in lpt_setup_backlight() is
made redundant.

v9:
* Drop the intel_panel_invert_pwm_level() call in lpt_setup_backlight()
* Remove leftover detritus from lpt_setup_backlight()
v8:
* Go back to getting initial brightness level with
  intel_pwm_get_backlight(), the other fix we had was definitely wrong.
v7:
* Use panel->backlight.pwm_funcs->get() to get the backlight level in
  intel_pwm_setup_backlight(), lest we upset lockdep
* Rebase
* Rename intel_panel_sanitize_pwm_level() to intel_panel_invert_pwm_level()
v6:
* Make sure to grab connection_mutex before calling
  intel_pwm_get_backlight() in intel_pwm_setup_backlight()
v5:
* Fix indenting warnings from checkpatch
v4:
* Fix commit message
* Remove outdated comment in intel_panel.c
* Rename pwm_(min|max) to pwm_level_(min|max)
* Use intel_pwm_get_backlight() in intel_pwm_setup_backlight() instead of
  indirection
* Don't move intel_dp_aux_init_bcklight_funcs() call to bottom of
  intel_panel_init_backlight_funcs() quite yet
v3:
* Reuse intel_panel_bl_funcs() for pwm_funcs
* Explain why we drop lpt_get_backlight()

68fd1faa92 drm/i915: Reuse the async_flip() hook for the async flip disable w/a
On some platforms we need to trigger an extra async flip with
the async flip bit disabled, and then wait for the next vblank
until the async flip bit off state will actually latch.

Currently the w/a is just open coded for skl+ universal planes.
Instead of doing that lets reuse the .async_flip() hook for this
purpose since it needs to write the exact same set of registers.
In order to do this we'll just have the caller pass in the state
of the async flip bit explicitly.
