163e3bcbca drm/amd/display: fix initial bounding box values for dcn3.02
[Why]
Initial bounding box values are updated in dcn30_update_bw_bounding_box
 but they use dcn3_0_soc and dcn3_0_ip instead of dcn3_02_soc and
 dcn3_02_ip

[How]
Add dcn302_update_bw_bounding_box and
 dcn302_get_optimal_dcfclk_fclk_for_uclk so it uses
 dcn3_02_soc and dcn3_02_ip.
Use sr_exit_time_us, sr_enter_plus_exit_time_us,
 from dcn30 on dcn302 to fix flicker on eDP.

43c7887313 drm/amd/display: implement support for DID2.0 dsc passthrough
[Why]
Some panels contain active converters (e.g. DP to MIPI) which only support
restricted DSC configurations.  DID2.0 adds support for such displays to
explicitly define per timing BPP restrictions on DSC.  Ignoring these
restrictions leads to blackscreen.

[How]
Add parsing in DID2.0 parser to get this bpp info.
Add support in DSC module to constraint target bpp based

4fa6a75128 drm/amd/display: fix calculation for the pwl backlight curve

The PWL backlight curve is used by the firmware to convert between
brightness and linear PWM value.
Driver has a backlight LUT, but the firmware holds a PWL curve and
interpolates between points.

The calculations are incorrect leading to slightly off backlight values
being programmed.

fa2a3786c4 drm/amd/display: reuse current context instead of recreating one
[Why]
Currently we discard the current context and recreate it. The current
context is what is applied to the HW so we should be re-using this
rather than creating a new context.

Recreating the context can lead to mismatch between new context and the
current context

For example: gsl groups get changed when we create a new context this
can cause issues in a multi display config (with flip immediate) because
we don't align the existing gsl groups in the new and current context.
If we reuse the current context the gsl group assignment stays the same.

[How]
Instead of discarding the current context, we instead just copy the
current state and add/remove planes and streams.

aec1d8703e drm/amdgpu/pm: Account for extra separator characters in sysfs interface
Currently, the the input to the pp_od_clk_voltage sysfs interface has
two adjacent separator characters, i.e. "\n\0", then we try to parse an
argument out of the empty string, whereas we really should just ignore
this case, and treat any number of adjacent separators as one separator
for arguments.

We do this here by simply skipping the argument parsing for all
empy-string arguments.

An example test case would be `echo 's  1 900' > pp_od_clk_voltage`
(note the two spaces after the 's'.

This also solves the issue where the written string ends with both a
newline, and a nul-terminator, '\n\0', as is the case for `echo 's 1
900' > pp_od_clk_voltage` since the recent rebase.

Got lost during code rebase/merge. No need to port this to other
branches.

3b7bbb3619 drm/i915/dp: Prevent setting the LTTPR LT mode if no LTTPRs are detected
Atm, the driver programs explicitly the default transparent link
training mode (0x55) to DP_PHY_REPEATER_MODE even if no LTTPRs are
detected.

This conforms to the spec (3.6.6.1):
"DP upstream devices that do not enable the Non-transparent mode of
 LTTPRs shall program the PHY_REPEATER_MODE register (DPCD Address
 F0003h) to 55h (default) prior to link training"

however writing the default value to this DPCD register seems to cause
occasional link training errors at least for a DELL WD19TB TBT dock, when
no LTTPRs are detected.

Writing to DP_PHY_REPEATER_MODE will also cause an unnecessary timeout
on systems without any LTTPR.

To fix the above two issues let's assume that setting the default mode
is redundant when no LTTPRs are detected. Keep the existing behavior and
program the default mode if more than 8 LTTPRs are detected or in case
the read from DP_PHY_REPEATER_CNT returns an invalid value.

6ede6b0616 drm/i915: Implement async flips for vlv/chv
Add support for async flips on vlv/chv. Unlike all the other
platforms vlv/chv do not use the async flip bit in DSPCNTR and
instead we select between async vs. sync flips based on the
surface address register. The normal DSPSURF generates sync
flips DSPADDR_VLV generates async flips. And as usual the
interrupt bits are different from the other platforms.

cda195f13a drm/i915: Implement async flips for bdw
Implement async flip support for BDW. The implementation is
similar to the skl+ code. And just like skl/bxt/glk bdw also
needs the disable w/a, thus we need to plumb the desired state
of the async flip all the way down to i9xx_plane_ctl_crtc().

According to the spec we do need to bump the surface alignment
to 256KiB for this. Async flips require an X-tiled buffer so
we don't have to worry about linear.

cb80705549 drm/i915: Limit plane stride to below TILEOFF.x limit
Limit pre-skl plane stride to below 4k or 8k pixels (depending on
the platform). We do this in order guarantee that TILEOFF/OFFSET.x
does not get too big.

Currently this is not a problem as we align SURF to 4k, and so
TILEOFF/OFFSET only have to deal with a single tile's worth of
pixels. But for async flips we're going to have to bump SURF
alignment to 256k, and thus we can no longer guarantee
TILEOFF/OFFSET.x will stay within acceptable bounds. We can avoid
this by borrowing a trick from the skl+ code and limit the max
plane stride to whatever value we can fit into TILEOFF/OFFSET.x.

The slight downside is that we may end up doing GTT remapping in
a few more cases where previously we did not have to. But since
that will only happen with huge buffers I'm not really concerned
about it.

5d0c938ec9 drm/i915/gen11+: Only load DRAM information from pcode
Up to now we were reading some DRAM information from MCHBAR register
and from pcode what is already not good but some GEN12(TGL-H and ADL-S)
platforms have MCHBAR DRAM information in different offsets.

This was notified to HW team that decided that the best alternative is
always apply the 16gb_dimm watermark adjustment for GEN12+ platforms
and read the remaning DRAM information needed to other display
programming from pcode.

So here moving the DRAM pcode function to intel_dram.c, removing
the duplicated fields from intel_qgv_info, setting and using
information from dram_info.

v2:
- bring back num_points to intel_qgv_info as num_qgv_point can be
overwritten in icl_get_qgv_points()
- add gen12_get_dram_info() and simplify gen11_get_dram_info()

Attempting to use such a connector with mutter leads to a crash of mutter

it's state, but without grabbing any of the appropriate modesetting locks
to do so.

That being said however: trying to grab modesetting locks in our audio
callbacks would be very painful due to the potential for locking inversion
between HDA and DRM. So, let's instead just copy what i915 does again - add
our own audio lock to protect audio related state, and store each audio
enabled connector in each nouveau_encoder struct so that we don't need to
check any atomic states.

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.

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.

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.

860cc26a01 drm/amdgpu: Add RLC_PG_DELAY_3 for Vangogh
Driver should enable the CGPG feature for RLC in safe mode to
prevent any misalignment or conflict in middle of any power
feature entry/exit sequence.
Achieved by setting RLC_PG_CNTL.GFX_POWER_GATING_ENABLE = 0x1,
and RLC_PG_DELAY_3.CGCG_ACTIVE_BEFORE_CGPG to the desired CGPG
hysteresis value in refclk count.

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.]

a2dd2ff50c drm/i915/gt: Skip over completed active execlists, again
Now that we are careful to always force-restore contexts upon rewinding
(where necessary), we can restore our optimisation to skip over
completed active execlists when dequeuing.
