de572e881b drm/i915/display/adlp: Allow PSR2 to be enabled
With all the recent fixes PSR2 is properly working in Alderlake-P but
due to some issues that don't have software workarounds it will not be
supported in display steppings older than B0.

Even with this patch PSR2 will no be enabled by default in ADL-P, it
still requires enable_psr2_sel_fetch to be set to true, what some
of our tests does.

1163649a04 drm/i915/display/adlp: Optimize PSR2 power-savings in corner cases
The Wa_14014971508 is required to fix scanout when a feature that i915
do not support is enabled and this feature is not planned to be enabled
for adlp.

Keeping this workaround enabled can badly hurt power-savings when
a full frame fetch is required(see psr2_sel_fetch_plane_state_supported()
and psr2_sel_fetch_pipe_state_supported()).

Here a example that could badly hurt power-savings, userspace does
a page flip to a rotated plane, so CONTINUOS_FULL_FRAME set.
But then for a whole 30 seconds nothing in the screen requires updates
but because CONTINUOS_FULL_FRAME is set, it will not go into DC5/DC6.

Reverting Wa_14014971508 fixes that, as only a single frame will be
sent and then display can go to DC5/DC6 for those 30 seconds of
idleness.

ef39826c12 drm/i915/display: Fix glitches when moving cursor with PSR2 selective fetch enabled
Legacy cursor APIs are handled by intel_legacy_cursor_update(), that
calls drm_atomic_helper_update_plane() when going through the
slow/atomic path to update cursor, what was the case for PSR2
selective fetch.

drm_atomic_helper_update_plane() sets
drm_atomic_state->legacy_cursor_update to true when updating the
cursor plane, to allow several cursor updates to happen within the
same frame, as userspace does that.
If drivers waited for a vblank increment at the end of every cursor
movement that would cause a visible lag in the cursor.

But this optimization do not properly work with PSR2 selective fetch
dirt area calculation, for example if within a single frame the cursor
had 3 moves the final dirt area programmed to PSR2_MAN_TRK_CTL would
be based in the second movement as old state and third movement as new
state, not updating the area where cursor was in the first state.

So here switching back to the fast path approach in
intel_legacy_cursor_update() and handling cursor movements as
frontbuffer rendering(psr_force_hw_tracking_exit()), that is not the
most optimal for power-savings but is the solution that we have until
mailbox style updates is implemented.

Also removing the cursor workaround as not it is properly undestand
the issue and is know that it will never cover all the cases.

34ac6b651f drm/i915/display: Handle frontbuffer rendering when PSR2 selective fetch is enabled
When PSR2 selective fetch is enabled writes to CURSURFLIVE alone do
not causes the panel to be updated when doing frontbuffer rendering.

From what I was able to figure from experiments the writes to
CURSURFLIVE takes PSR2 from deep sleep but panel is not updated
because PSR2_MAN_TRK_CTL has no start and end region set.

As we don't have the dirt area from current flush and invalidate API
and even if we did userspace could do several draws to frontbuffer and
we would need a way to append all the damaged areas of all the draws
that need to be part of next frame.

So here only programing PSR2_MAN_TRK_CTL to do a single full frame
fetch.

It is a safe approach as if scanout is in the visible area
the single full frame will only be visible for hardware in the next
frame because of the double buffering, and if scanout is in vblank
area it will be draw in the current frame.

No need to disable PSR and wait a few miliseconds to enable it again.

5da579cff3 drm/i915/display: Drop unnecessary frontbuffer flushes
This unnecessary flushes are hurting power-savings are it causes
features like PSR, FBC and DRRS to disable it self to handle
frontbuffer rendering, below some explanation of why each removed
call is not necessary.

The flush in intel_prepare_plane_fb() is not required as framebuffer
will be flipped and power-saving features do the proper flip handling
in hardware.

intel_find_initial_plane_obj() flush is not required because it is
only executed during driver load and at this point the power-saving
features are not even enabled.

And the last one intelfb_create(), is also not required as at this
point the fbdev was just allocated, userspace will draw on
it what will trigger frontbuffer invalidates and flushes later on.

ac220f5f75 drm/i915/display/psr: Handle plane and pipe restrictions at every page flip
PSR2 selective is not supported over rotated and scaled planes.
We had the rotation check in intel_psr2_sel_fetch_config_valid()
but that code path is only execute when a modeset is needed and
those plane parameters can change without a modeset.

Pipe selective fetch restrictions are also needed, it could be added
in intel_psr_compute_config() but pippe scaling is computed after
it is executed, so leaving as is for now.
There is no much loss in this approach as it would cause selective
fetch to not enabled as for alderlake-P and newer will cause it to
switch to PSR1 that will have the same power-savings as do full pipe
fetch.

Also need to check those restricions in the second
for_each_oldnew_intel_plane_in_state() loop because the state could
only have a plane that is not affected by those restricitons but
the damaged area intersect with planes that has those restrictions,
so a full pipe fetch is required.

v2:
- also handling pipe restrictions

1e9ae61d17 drm/i915: Clear leftover DP vswing/preemphasis values before modeset
Currently we clear the leftover vswing/preemphasis values only
at the start of link training. That means the initial vswing
programming performed during modeset is going to use stale values
left over from the previous link training sequence, and then at
the start of link training we're going to reset the levels back
to 0. Seems much better to make sure we start with level 0 from
the get go.

Additionally if LTTPRs are present the leftover vswing/preemphasis
values are those of the last link in the chain, so not the values
that our PHY is even using after a successful link training sequence.

So let's make sure everything is cleared up before we start
programming anything.

We can conveniently cross check the bitmask for invalid

One slight change in behaviour is that we no longer read out
the AONOFF->force_pfit.pfit bit for all the enabled "panel

be illegal so no big loss. Also the AONOFF selection should
only ever be used on HSW, which only has the EDP transcoder

2709abc8d1 drm/i915/fbc: Allow FBC with Yf tiling
FBC+Yf tiling seems to work just fine, and unlike with linear
the hardware does appear to correctly calculate the CFB stride
with using the override stride on both cfl and glk. So no need
for any additional tweaks.

Stop using HBR2/3 support as a proxy for TPS3/4 support.
The two are no longer 1:1 in the hardware, arguably they
never were due to HSW ULX which does support TPS3 while
being limited to HBR1.

In more recent times GLK gained support for TPS4 while
being limited to HBR2. And on CNL+ some ports support
HBR3 while others are limited to HBR2, but all ports

When using a panel with a fixed mode we don't change the refresh
rate of the display. Reject any user requested mode which doesn't
match that fixed refresh rate.

Unfortunately when Xorg sees the scaling_mode property on the

we have to give it some extra latitude so that we don't start to
reject all of it.

Let's introduce a compute_config() helper for fixed mode panels.
For now all it does is the fixed_mode->adjusted_mode copy.

Note that with sDVO we have to ask the external encoder chip

to adjusted_mode copy done by intel_panel_compute_config() is
redundant, but we still want to use it to do other checks for us

intel_sdvo_get_preferred_input_mode() overwrites adjusted_mode

00fc3787d2 drm/i915: Reject modes that don't match fixed_mode vrefresh
When using a fixed mode we won't change the refresh rate ever.
So filter out all modes that don't match the fixed_mode's refresh
rate.

I'm going to declare the "rounded to nearest Hz refresh
rates must match" approach good enough for now.

Note that we could start supporting multiple refresh rates
with panels that can do it, but that would mean replacing
the single fixed mode concept with a list of fixed modes.
Then we could look for the closest match to the user's
requested refresh rate and use that. But all of that would
be a fair bit of work so we'll leave it for later.

This changes the behaviour to match what we do for eDP, ie.

sized modes which will be handled by the panel fitter just
as before. The difference is that we can no longer report

The PHY ownership release->AUX PW disable steps during a modeset
disable->PHY disconnect sequence can hang the system if the PHY
disconnect happens after disabling the PHY's PLL. The spec doesn't
require a specific order for these two steps, so this issue is still

3e0abc7661 drm/i915/tc: Fix TypeC PHY connect/disconnect logic on ADL-P
So far TC-cold was blocked only for the duration of TypeC mode resets.
The DP-alt and legacy modes require TC-cold to be blocked also whenever
the port is in use (AUX transfers, enable modeset), and this was ensured
by the held PHY ownership flag. On ADL-P this doesn't work, since the
PHY ownership flag is in a register backed by the PW#2 power well.
Whenever this power well is disabled the ownership flag is cleared by
the HW under the driver.

The only way to cleanly release and re-acquire the PHY ownership flag
and also allow for power saving (by disabling the display power wells
and reaching DC5/6 states) is to hold the TC-cold blocking power domains
while the PHY is connected and disconnect/reconnect the PHY on-demand
around AUX transfers and modeset enable/disables. Let's do that,
disconnecting a PHY with a 1 sec delay after it becomes idle. For
consistency do this on all platforms and TypeC modes.

8e8289a00e drm/i915/tc: Avoid using legacy AUX PW in TBT mode
For the ADL-P TBT mode the spec doesn't require blocking TC-cold by
using the legacy AUX power domain. To avoid the timeouts that this would
cause during PHY disconnect/reconnect sequences (which will be more
frequent after a follow-up change) use the TC_COLD_OFF power domain in
TBT mode on all platforms. On TGL this power domain blocks TC-cold via a
PUNIT command, while on other platforms the domain just takes a runtime
PM reference.

If the HPD live status indicates that the port mode needs to be reset
- for instance after switching from TBT to a DP-alt sink - still take
the AUX domain, since the IOM firmware handshake requires this.

09bbdd8730 drm/i915/fbc: Allow higher compression limits on FBC1
On FBC1 we can specify an arbitrary cfb stride. The hw will
simply throw away any compressed line that would exceed the
specified limit and keep using the uncompressed data instead.
Thus we can allow arbitrary compression limits.

The one thing we have to keep in mind though is that the cfb
stride is specified in units of 32B (gen2) or 64B (gen3+).
Fortunately X-tile is already 128B (gen2) or 512B (gen3+) wide
so as long as we limit outselves to the same 4x compression
limit that FBC2 has we are guaranteed to have a sufficiently
aligned cfb stride.

to just do it on everything.

Also the hardware no longer seems to misclaculate the CFB stride

linear unless the stride is misaligned.

bdc1a2d2a3 drm/i915/fbc: Rework cfb stride/size calculations
The code to calculate the cfb stride/size is a bit of mess.
The cfb size is getting calculated based purely on the plane
stride and plane height. That doesn't account for extra
alignment we want for the cfb stride. The gen9 override
stride OTOH is just calculated based on the plane width, and
it does try to make things more aligned but any extra alignment
added there is not considered in the cfb size calculations.
So not at all convinced this is working as intended. Additionally
the compression limit handling is split between the cfb allocation
code and g4x_dpfc_ctl_limit() (for the 16bpp case), which is just
confusing.

Let's streamline the whole thing:
- Start with the plane stride, convert that into cfb stride (cfb is
  always 4 bytes per pixel). All the calculations will assume 1:1
  compression limit since that will give us the max values, and we
  don't yet know how much stolen memory we will be able to allocate
- Align the cfb stride to 512 bytes on modern platforms. This guarantees
  the 4 line segment will be 512 byte aligned regardles of the final
  compression limit we choose later. The 512 byte alignment for the
  segment is required by at least some of the platforms, and just doing
  it always seems like the easiest option
- Figure out if we need to use the override stride or not. For X-tiled
  it's never needed since the plane stride is already 512 byte aligned,
  for Y-tiled it will be needed if the plane stride is not a multiple
  of 512 bytes, and for linear it's apparently always needed because the
  hardware miscalculates the cfb stride as PLANE_STRIDE*512 instead of
  the PLANE_STRIDE*64 that it use with linear.
- The cfb size will be calculated based on the aligned cfb stride to
  guarantee we actually reserved enough stolen memory and the FBC hw
  won't end up scribbling over whatever else is allocated in stolen
- The compression limit handling we just do fully in the cfb allocation
  code to make things less confusing

v2: Write the min cfb segment stride calculation in a more
    explicit way to make it clear what is going on
v3: Remeber to update fbc->limit when changing to 16bpp

9ce5884e51 drm/i915/display: Only keep PSR enabled if there is active planes
PSR always had a requirement to only be enabled if there is active
planes but not following that never caused any issues.
But that changes in Alderlake-P, leaving PSR enabled without
active planes causes transcoder/port underruns.

Similar behavior was fixed during the pipe disable sequence by
commit 84030adb9e ("drm/i915/display: Disable audio, DRRS and PSR before planes").

intel_dp_compute_psr_vsc_sdp() had to move from
intel_psr_enable_locked() to intel_psr_compute_config() because we
need to be able to disable/enable PSR from atomic states without
connector and encoder state.

of the power-of-two sized stride and the 2MB surface offset alignment

We can only remap the tiles on the main surface, not the tiles on the

the POT size padded main surface stride (by programming the AUX

requires that either the main surface stride is 8 tiles or that the
stride is 16 tiles aligned (= 64 kbytes, the area mapped by one AUX
PTE).

aad24cc4bd drm/i915: Use tile block based dimensions for CCS origin x, y check
The tile size for all surface types is 4 kbyte (or 2 kbyte on old
platforms), with the exception of the TGL/ADL CCS surface where the tile
size is 64 bytes. To be able to remap CCS FBs the CCS surface tile needs
to be defined as 4 kbyte as well (the granularity of GTT pages in a
remapped view).

The only place using the dimension of the 64 byte CCS area is the initial
check for the main vs. CCS plane origin coordinate match. To prepare for
adding support for remapping CCS FBs let's call the 64 byte CCS area a
'tile block' and add a helper to retrieve the dimensions for it.

Wa_14014971508 is still in pending status in BSpec but by
the time this is reviewed and ready to be merged it will be finalized.

af7ea1e22a drm/i915/display/psr: Use drm damage helpers to calculate plane damaged area
drm_atomic_helper_damage_iter_init() + drm_atomic_for_each_plane_damage()
returns the full plane area in case no damaged area was set by
userspace or it was discarted by driver.

This is important to fix the rendering of userspace applications that
does frontbuffer rendering and notify driver about dirty areas but do
not set any dirty clips.

With this we don't need to worry about to check and mark the whole
area as damaged in page flips.

Another important change here is the move of
drm_atomic_add_affected_planes() call, it needs to called late
otherwise the area of all the planes would be added to pipe_clip and
not saving power.

8c66081b0b drm/i915: s/pipe/transcoder/ when dealing with PIPECONF/TRANSCONF
PIPECONF becamse TRANSCONF when HSW introduced the EDP transcoder.
Bigjoiner is making life even more confusing by introducing
a N:1 relationship between pipes and transcoders. In that case
we only enable/configure the transcoder corresponding to the
master pipe. Let's do some renames to make it clear we're dealing
with the transcoder rather than pipe when it comes to
PIPECONF/TRANSCONF.

I decided to leave the _cpu_ part out from the function/macro
names since the PCH transcoder related stuff already has a
_pch_ in their name. So shouldn't be possible to confuse them.

Users reported that after commit 2bbd6dba84 ("drm/i915: Try to use

failure"), the screen starts to have wobbly effect.

Commit a5c936add6 ("drm/i915/dp: Use slow and wide link training for
everything") doesn't help either, that means the affected eDP 1.2 panels
only work with max params.

So use max params for panels < eDP 1.4 as Windows does to solve the
issue.

 - Do the eDP rev check in intel_edp_init_dpcd()

v2:

After DPRX link training, intel_dp_link_train_phy() did not

i915 driver would not run into link train fallback function.
And no hotplug uevent would be received by user space application.

4e79e12f5b drm/i915/dp: Add support for out-of-bound hotplug events
On some Cherry Trail devices, DisplayPort over Type-C is supported through
a USB-PD microcontroller (e.g. a fusb302) + a mux to switch the superspeed
datalines between USB-3 and DP (e.g. a pi3usb30532). The kernel in this
case does the PD/alt-mode negotiation itself, rather then everything being
handled in firmware.

So the kernel itself picks an alt-mode, tells the Type-C "dongle" to switch
to DP mode and sets the mux accordingly. In this setup the HPD pin is not
connected, so the i915 driver needs to respond to a software event and scan
the DP port for changes manually.

This commit adds support for this. Together with the recent addition of
DP alt-mode support to the Type-C subsystem this makes DP over Type-C
work on these devices.

a481d0e80e drm/i915: Associate ACPI connector nodes with connector entries (v2)
On Intel platforms we know that the ACPI connector device
node order will follow the order the driver (i915) decides.
The decision is made using the custom Intel ACPI OpRegion
(intel_opregion.c), though the driver does not actually know
that the values it sends to ACPI there are used for
associating a device node for the connectors, and assigning
address for them.

In reality that custom Intel ACPI OpRegion actually violates
ACPI specification (we supply dynamic information to objects
that are defined static, for example _ADR), however, it
makes assigning correct connector node for a connector entry
straightforward (it's one-on-one mapping).

Changes in v2 (Hans de goede):
- Take a reference on the fwnode which we assign to the connector,
  for ACPI nodes this is a no-op but in the future we may see
  software-fwnodes assigned to connectors which are ref-counted.

3e31d05743 drm/i915/hdcp: reuse rx_info for mst stream type1 capability check
On some MST docking stations, rx_info can only be read after
RepeaterAuth_Send_ReceiverID_List and the RxStatus READY bit is set
otherwise the read will return -EIO.

This behavior causes the mst stream type1 capability test to fail to
read rx_info and determine if the topology supports type1 and fallback
to type0.

To fix this, check for type1 capability when we receive rx_info within
the AKE flow when we read RepeaterAuth_Send_ReceiverID_List instead
of an explicit read just for type1 capability checking.

This does require moving where we set stream_types to after
hdcp2_authenticate_sink() when we get rx_info but this occurs before we
do hdcp2_propagate_stream_management_info.

Also, legacy HDCP 2.0/2.1 are not type 1 capable either so check for
that as well.

Changes since v5:
 - rename intel_set_stream_types() to intel_hdcp_prepare_streams()
   (Anshuman)

Changes since v4:
 - move topology_type1_capable to intel_digital_port and rename it as
   hdcp_mst_type1_capable (Anshuman)
 - make a helper function intel_set_stream_types() to set stream types
   in hdcp2_authenticate_and_encrypt() (Anshuman)
 - break on failure to set stream types and retry instead of returning
 - remove no longer used declaration for streams_type1_capable()

Changes since v2:
 - Remove no longer used variables in _intel_hdcp2_enable()

0f317ebb5f drm/i915/hdcp: read RxInfo once when reading RepeaterAuth_Send_ReceiverID_List
When reading RepeaterAuth_Send_ReceiverID_List, RxInfo is read by itself
once to retrieve the DEVICE_COUNT to calculate the size of the
ReceiverID list then read a second time as a part of reading ReceiverID
list.

On some MST docking stations, RxInfo can only be read after the RxStatus
READY bit is set otherwise the read will return -EIO. The spec states that
the READY bit should be cleared as soon as RxInfo has been read.

In this case, the first RxInfo read succeeds but after the READY bit is
cleared, the second read fails.

Fix it by reading RxInfo once and storing it before reading the rest of
RepeaterAuth_Send_ReceiverID_List once we know the size.

Modify get_receiver_id_list_size() to read and store RxInfo in the
message buffer and also parse DEVICE_COUNT so we know the size of
RepeaterAuth_Send_ReceiverID_List.

Afterwards, retrieve the rest of the message at the offset for
seq_num_V.

Changes in v5:
- Don't change the offset define for Send_ReceiverID_List
  When reading, update message offset to account for RxInfo being read

Changes in v4:
- rebase and edit commit message

Changes in v3:
- remove comment

Changes in v2:
- remove unnecessary moving of drm_i915_private from patch 1

58cfa3297a drm/i915/hdcp: update cp_irq_count_cached in intel_dp_hdcp2_read_msg()
Update cp_irq_count_cached when reading messages rather than when
writing a message to make sure the value is up to date and not
stale from a previously handled CP_IRQ.

AKE flow  doesn't always respond to a read with a ACK write msg.
E.g. AKE_Send_Pairing_Info will "timeout" because we received
a CP_IRQ for reading AKE_Send_H_Prime but no write occurred between that
and reading AKE_Send_Pairing_Info so cp_irq_count_cached is stale
causing the wait to return right away rather than waiting for a new
CP_IRQ.

So far, DCS backlight driver hardcode (0xFF) for max brightness level.
MIPI DCS spec allow max 0xFFFF for set_display_brightness (51h) command.
And VBT brightness precision bits can support 8 ~ 16 bits.

We should set correct precision bits in VBT that meet panel's request.
Driver can refer to this setting then configure max brightness level
in DCS backlight driver properly.

v2: modify variable name brightness_precision_bits instead of
    max_brightness_level.
v3: fix checkpatch warning.

6fd5a7c92e drm/i915/dp: Fix eDP max rate for display 11+
intel_dp_set_source_rates() calls intel_dp_is_edp(), which is unsafe to
use before intel_encoder->type is set. This causes incorrect max source
rate to be used for display 11+. On EHL and JSL, HBR3 is used instead of
HBR2, and on the other affected platforms, HBR2 is used instead of HBR3.

Move intel_dp_set_source_rates() to after intel_encoder->type is
set. Add comment to intel_dp_is_edp() describing unsafe usages. Cleanup
intel_dp_init_connector() while at it.

Note: The same change was originally added as commit 680c45c767
("drm/i915/dp: Correctly advertise HBR3 for GEN11+"), but later reverted
due to issues in CI in commit d391301960 ("Revert "drm/i915/dp:
Correctly advertise HBR3 for GEN11+"").

Pull drm updates from Dave Airlie:
 "Highlights:

   - i915 has seen a lot of refactoring and uAPI cleanups due to a
     change in the upstream direction going forward

     This has all been audited with known userspace, but there may be
     some pitfalls that were missed.

   - i915 now uses common TTM to enable discrete memory on DG1/2 GPUs

   - i915 enables Jasper and Elkhart Lake by default and has preliminary
     XeHP/DG2 support

   - amdgpu adds support for Cyan Skillfish

   - lots of implicit fencing rules documented and fixed up in drivers

   - msm now uses the core scheduler

   - the irq midlayer has been removed for non-legacy drivers

   - the sysfb code now works on more than x86.

  Otherwise the usual smattering of stuff everywhere, panels, bridges,
  refactorings.

Commit a5c936add6 ("drm/i915/dp: Use slow and wide link training for

only work with max params.

So use max params for panels < eDP 1.4 as Windows does to solve the

So let's keep the nuke, and just extend it backwards to cover
all the platforms by doing it a bit higher up.

abd9d66a05 drm/i915/display: Fix the 12 BPC bits for PIPE_MISC reg
Till DISPLAY12 the PIPE_MISC bits 5-7 are used to set the
Dithering BPC, with valid values of 6, 8, 10 BPC.
For ADLP+ these bits are used to set the PORT OUTPUT BPC, with valid
values of: 6, 8, 10, 12 BPC, and need to be programmed whether
dithering is enabled or not.

This patch:
-corrects the bits 5-7 for PIPE MISC register for 12 BPC.
-renames the bits and mask to have generic names for these bits for
dithering bpc and port output bpc.

v3: Added a note for MIPI DSI which uses the PIPE_MISC for readout
for pipe_bpp. (Uma Shankar)

v2: Added 'display' to the subject and fixes tag. (Uma Shankar)

UAPI Changes:

- Add I915_MMAP_OFFSET_FIXED

  On devices with local memory `I915_MMAP_OFFSET_FIXED` is the only valid
  type. On devices without local memory, this caching mode is invalid.

  As caching mode when specifying `I915_MMAP_OFFSET_FIXED`, WC or WB will
  be used, depending on the object placement on creation. WB will be used
  when the object can only exist in system memory, WC otherwise.

  Userspace: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11888

- Reinstate the mmap ioctl for (already released) integrated Gen12 platforms

  Rationale: Otherwise media driver breaks eg. for ADL-P. Long term goal is
  still to sunset the IOCTL even for integrated and require using mmap_offset.

- Reject caching/set_domain IOCTLs on discrete

  Expected to become immutable property of the BO

- Disallow changing context parameters after first use on Gen12 and earlier
- Require setting context parameters at creation on platforms after Gen12

  Rationale (for both): Allow less dynamic changes to the context to simplify
  the implementation and avoid user shooting theirselves in the foot.

- Drop I915_CONTEXT_PARAM_RINGSIZE

  Userspace PR for compute-driver has not been merged

- Drop I915_CONTEXT_PARAM_NO_ZEROMAP

  Userspace PR for libdrm / Beignet was never landed

- Drop CONTEXT_CLONE API

  Userspace PR for Mesa was never landed

- Drop getparam support for I915_CONTEXT_PARAM_ENGINES

  Only existed for symmetry wrt. setparam, never used.

- Disallow bonding of virtual engines

  Drop the prep work, no hardware has been released needing it.

- (Implicit) Disable gpu relocations

  Media userspace was the last userspace to still use them. They
  have converted so performance can be regained with an update.

70418a6871 drm/i915/display: Fix the 12 BPC bits for PIPE_MISC reg
Till DISPLAY12 the PIPE_MISC bits 5-7 are used to set the
Dithering BPC, with valid values of 6, 8, 10 BPC.
For ADLP+ these bits are used to set the PORT OUTPUT BPC, with valid
values of: 6, 8, 10, 12 BPC, and need to be programmed whether
dithering is enabled or not.

This patch:
-corrects the bits 5-7 for PIPE MISC register for 12 BPC.
-renames the bits and mask to have generic names for these bits for
dithering bpc and port output bpc.

v3: Added a note for MIPI DSI which uses the PIPE_MISC for readout
for pipe_bpp. (Uma Shankar)

v2: Added 'display' to the subject and fixes tag. (Uma Shankar)

233624e0d5 drm/i915: Apply CMTG clock disabling WA while DPLL0 is enabled
CI test results/further experiments show that the workaround added in

commit 573d7ce4f6 ("drm/i915/adlp: Add workaround to disable CMTG clock gating")

can be applied only while DPLL0 is enabled. If it's disabled the
TRANS_CMTG_CHICKEN register is not accessible. Accordingly move the WA
to DPLL0 HW state sanitization and enabling.

This fixes an issue where the WA won't get applied (and a WARN is thrown
due to an unexpected value in TRANS_CMTG_CHICKEN) if the driver is
loaded without DPLL0 being enabled: booting without BIOS enabling an
output with this PLL, or reloading the driver.

While at it also add a debug print for the unexpected register value.

DG1 and XE_PLD platforms has Audio MMIO/VERBS lies in PG0 power
well. Adjusting the power domain accordingly to
POWER_DOMAIN_AUDIO_MMIO for audio detection and
POWER_DOMAIN_AUDIO_PLAYBACK for audio playback.

While doing this it requires to use POWER_DOMAIN_AUDIO_MMIO
power domain instead of POWER_DOMAIN_AUDIO in crtc power domain mask
and POWER_DOMAIN_AUDIO_PLAYBACK with intel_display_power_{get, put}
to enable/disable display audio codec power.

It will save the power in use cases when DP/HDMI connectors
configured with PIPE_A without any audio playback.

v1: Changes since RFC

v2:
- Not allowe DC states when AUDIO_MMIO domain enabled. [Imre]

interception scheme to manage DP PHY settings (e.g. adjusting Swing/Pre-emphasis

573d7ce4f6 drm/i915/adlp: Add workaround to disable CMTG clock gating
The driver doesn't depend atm on the common mode timing generator
functionality (it would be used for some power saving feature and panel
timing synchronization), however DMC will corrupt the CMTG registers
across DC5 entry/exit sequences unless the CMTG clock gating is
disabled. This in turn can lead to at least the DPLL0/1 configuration
getting stuck at their last state, which means we can't reprogram them
to a new config.

Add the corresponding Bspec workaround to prevent the above.

v2: Fix checkpatch errors. (CI, Jose)

ba3b049f47 drm/i915/adl_p: Allow underrun recovery when possible
ADL_P requires that we disable underrun recovery when downscaling (or
using the scaler for YUV420 pipe output), using DSC, or using PSR2.
Otherwise we should be able to enable the underrun recovery.

On DG2 we need to keep underrun recovery disabled at all times, but the
chicken bit in PIPE_CHICKEN has an inverted meaning (it's an enable bit
instead of disable).

v2:
 - Reverse the condition (clear the disable bit when supported, set
   disable bit when not supported).

Not following it did not caused any problems up to Alderlake-P but
for this platform it causes underruns during the PSR2 disable

Specification don't mention that DRRS should be disabled before planes

192fbfb767 drm/i915: Implement PSF GV point support
PSF GV points are an additional factor that can limit the
bandwidth available to display, separate from the traditional
QGV points.  Whereas traditional QGV points represent possible
memory clock frequencies, PSF GV points reflect possible
frequencies of the memory fabric.

Switching between PSF GV points has the advantage of incurring
almost no memory access block time and thus does not need to be
accounted for in watermark calculations.

This patch adds support for those on top of regular QGV points.
Those are supposed to be used simultaneously, i.e we are always
at some QGV and some PSF GV point, based on the current video
mode requirements.
Bspec: 64631, 53998

v2: Seems that initial assumption made during ml conversation
    was wrong, PCode rejects any masks containing points beyond
    the ones returned, so even though BSpec says we have around
    8 points theoretically, we can mask/unmask only those which
    are returned, trying to manipulate those beyond causes a
    failure from PCode. So switched back to generating mask
    from 1 - num_qgv_points, where num_qgv_points is the actual
    amount of points, advertised by PCode.

v3: - Extended restricted qgv point mask to 0xf, as we have now
      3:2 bits for PSF GV points(Matt Roper)
    - Replaced val2 with NULL from PCode request, since its not being
      used(Matt Roper)
    - Replaced %d to 0x%x for better readability(thanks for spotting)

DG2 doesn't have a SAGV or QGV points that determine memory bandwidth.
Instead it has a constant amount of memory bandwidth available to
display that does not need to be reduced based on the number of active

For simplicity, we'll just modify driver initialization to create a
single dummy QGV point with the proper amount of memory bandwidth,
rather than trying to query the pcode for this information.

46b0d7091c drm/i915: Make display workaround upper bounds exclusive
Workarounds are documented in the bspec with an exclusive upper bound
(i.e., a "fixed" stepping that no longer needs the workaround).  This
makes our driver's use of an inclusive upper bound for stepping ranges
confusing; the differing notation between code and bspec makes it very
easy for mistakes to creep in.

Let's switch the upper bound of our IS_{GT,DISP}_STEP macros over to use
an exclusive upper bound like the bspec does.  This also has the benefit
of helping make sure workarounds are properly handled for new minor
steppings that show up (e.g., an A1 between the A0 and B0 we already
knew about) --- if the new intermediate stepping pulls in hardware fixes
early, there will be an update to the workaround definition which lets
us know we need to change our code.  If the new stepping does not pull a
hardware fix earlier, then the new stepping will already be captured
properly by the "[begin, fix)" range in the code.

We'll probably need to be extra vigilant in code review of new
workarounds for the near future to make sure developers notice the new
semantics of workaround bounds.  But we just migrated a bunch of our
platforms from the IS_REVID bounds over to IS_{GT,DISP}_STEP, so people
are already adjusting to the new macros and now is a good time to make
this change too.

8e55f99c51 drm/i915: Invoke another _DSM to enable MUX on HP Workstation laptops
On HP Fury G7 Workstations, graphics output is re-routed from Intel GFX
to discrete GFX after S3. This is not desirable, because userspace will
treat connected display as a new one, losing display settings.

The expected behavior is to let discrete GFX drives all external
displays.

The platform in question uses ACPI method \_SB.PCI0.HGME to enable MUX.
The method is inside the another _DSM, so add the _DSM and call it
accordingly.

I also tested some MUX-less and iGPU only laptops with that _DSM, no
regression was found.

v4:
 - Rebase.
 - Change the DSM name to avoid confusion.
 - Move the function call to intel_opregion.

v3:
 - Remove BXT from names.
 - Change the parameter type.
 - Fold the function into intel_modeset_init_hw().

v2:
 - Forward declare struct pci_dev.

a193477271 drm/i915/dsc: abstract helpers to get bigjoiner primary/secondary crtc
Add a single point of truth for figuring out the primary/secondary crtc
for bigjoiner instead of duplicating the magic pipe +/- 1 in multiple
places.

Also fix the pipe validity checks to properly take non-contiguous pipes
into account. The current checks may theoretically overflow
i915->pipe_to_crtc_mapping[pipe], albeit with a warning, due to fused
off pipes, as INTEL_NUM_PIPES() returns the actual number of pipes on
the platform, and the check is for INTEL_NUM_PIPES() == pipe + 1.

Prefer primary/secondary terminology going forward.

v2:
- Improved abstractions for pipe validity etc.

cdad39216a drm/i915: keep backlight_enable on until turn eDP display off
This workaround is specific for a particular panel on Google
chromebook project. When user space daemon enter idle state.
It request adjust brightness to 0, turn backlight_enable signal
off and keep eDP main link active.

On general LCD, this behavior might not be a problem.
But on this panel, its tcon would expect source to execute
full eDP power off sequence after drop backlight_enable signal.
Without eDP power off sequence. Even source try to turn
backlight_enable signal on and restore proper brightness level.
This panel is not able to light on again.

This WA ignored the request from user space daemon to disable
backlight_enable signal and keep it on always. When user space
request kernel to turn eDP display off, kernel driver still
can control backlight_enable signal properly. It would not
impact standard eDP power off sequence.

v2: 1. modify the quirk name and debug messages.
    2. unregister backlight.power callback for specific device.
v3: 1. modify debug output messages.
    2. use DMI_EXACT_MATCH instead of DMI_MATCH.

Add a single point of truth for figuring out the primary/secondary crtc
for bigjoiner instead of duplicating the magic pipe +/- 1 in multiple
places.

Also fix the pipe validity checks to properly take non-contiguous pipes
into account. The current checks may theoretically overflow
i915->pipe_to_crtc_mapping[pipe], albeit with a warning, due to fused
off pipes, as INTEL_NUM_PIPES() returns the actual number of pipes on
the platform, and the check is for INTEL_NUM_PIPES() == pipe + 1.

Prefer primary/secondary terminology going forward.

151ec347b0 drm/i915: Force a TypeC PHY disconnect during suspend/shutdown
Disconnect TypeC PHYs during system suspend and shutdown, even with the
corresponding TypeC sink still plugged to its connector, since leaving
the PHY connected causes havoc at least during system resume in the
presence of an Nvidia card.

Note that this will only make a difference in the TypeC DP alternate
mode, since in Thunderbolt alternate mode the PHY is never owned by the
display engine and there is no notion of PHY ownership in legacy mode
(the display engine being the only possible owner in that mode and the
TypeC subsystem not having anything to do with the port in that case).

544021e3f2 drm/i915/jsl: Add W/A 1409054076 for JSL
When pipe A is disabled and MIPI DSI is enabled on pipe B,
the AMT KVMR feature will incorrectly see pipe A as enabled.
Set 0x42080 bit 23=1 before enabling DSI on pipe B and leave
it set while DSI is enabled on pipe B. No impact to setting
it all the time.
