Subject: [PATCH 001/131] drm/i915/dp: Fix determining SST/MST mode during MTP
 TU state computation

Determining the SST/MST mode during state computation must be done based
on the output type stored in the CRTC state, which in turn is set once
based on the modeset connector's SST vs. MST type and will not change as
long as the connector is using the CRTC. OTOH the MST mode indicated by
the given connector's intel_dp::is_mst flag can change independently of
the above output type, based on what sink is at any moment plugged to
the connector.

Fix the state computation accordingly.

Right or wrong, HAS_GMCH() has become a display only thing. The last
three users outside of display are in irq code. Reorder the if ladders
to stop using HAS_GMCH().

Subject: [PATCH 003/131] drm/i915/dp_mst: Use the correct connector while
 computing the link BPP limit on MST

Atm, on an MST link in DSC mode
intel_dp_compute_config_link_bpp_limits() calculates the maximum link
bpp limit using the MST root connector's DSC capabilities. That's not
correct in general: the decompression could be performed by a branch
device downstream of the root branch device or the sink itself.

Fix the above by passing to intel_dp_compute_config_link_bpp_limits()
the actual connector being modeset, containing the correct DSC
capabilities.

Subject: [PATCH 005/131] drm/i915/dp_mst: Validate compressed bpp vs. platform
 restrictions

Atm TGL supports only a fixed set of valid DSC compressed bpps
(6,8,10,12,15), but this is not taken into account while looking for a
bpp in the minimum..maximum compressed bpp range.

This happened to work only by chance since atm from the above min..max
range it's always the maximum bpp that is selected, which is one of the
above valid bpps (see mst_stream_dsc_compute_link_config() ->
intel_dp_dsc_nearest_valid_bpp()). Before selecting a bpp however, the
bpp's BW requirement should be checked wrt. to the MST total link BW;
after doing that - in a follow-up change - the validity of any bpp in
the min..max range must be ensured before the bpp is selected, do that
here.

Subject: [PATCH 006/131] drm/i915/dp_mst: Update the total link slot count
 early

A follow up change will check a selected bpp's BW requirement in
intel_dp_mtp_tu_compute_config(), however that requires the total link
slot count to be up-to-date. The latter in turn depends on the channel
encoding and hence the link rate used, so it can be set after the
link rate used is selected.

This also allows simplifying mst_stream_update_slots(), do that as well,
moving the function definition before its use.

Subject: [PATCH 007/131] drm/i915/dp_mst: Check BW limit on the local MST link
 early

Check the BW requirement of a selected compressed bpp against the total
MST link BW early. This didn't cause a problem, since all the BW limits
within the MST topology are checked during the later MST topology BW
check. However it doesn't make sense to defer the total link BW check,
since for resolving a BW limit issue due to this later also (a) requires
selecting a pipe to reduce its bpp, ending up reducing the bpp for
another pipe, which is not ideal (b) requires recomputing the state for
all CRTC/stream's in the topology which may slow down the commit
considerably (especially when using fractional bpps).

Based on the above, check a stream bpp's BW requirement against the MST
link's total BW early.

Ideally drm_dp_atomic_find_time_slots() should check internally the
corresponding PBN/TU slot BW against the total link BW, returning an
error if the check fails, however that change would also affect other
drivers, so leaving this for a follow-up.

v2: Rephrase description of pipe selection/bpp reduction in commit
    message. (Ankit)

Subject: [PATCH 008/131] drm/i915/dp_mst: Simplify computing the min/max
 compressed bpp limits

Adjusting the compressed bpp range min/max limits in
intel_dp_dsc_nearest_valid_bpp() is unnecessary:

- The source/sink min/max values are enforced already by the
  link_config_limits::min_bpp_x16/max_bpp_x16 values computed early in
  intel_dp_compute_config_link_bpp_limits().
- The fixed set of valid bpps are enforced already - for all bpps in the
  min .. max range by intel_dp_dsc_valid_compressed_bpp() called from
  intel_dp_mtp_tu_compute_config().

The only thing needed is limiting max compressed bpp below the
uncompressed pipe bpp, do that one thing only instead of calling
intel_dp_dsc_nearest_valid_bpp().

Subject: [PATCH 009/131] drm/i915/dp: Limit max link bpp properly to a
 fractional value on SST

The maximum link bpp - determined by the link BW for instance - can be
fractional, handle this properly during computing the link bpp on SST.

This keeps the pipe joiner specific maximum link bpp as a rounded-down
integer value still, changing that to a fractional value is left for
later.

v2: Align the min/max bpp value to the bpp step.

Subject: [PATCH 010/131] drm/i915/dp_mst: Add support for fractional
 compressed link bpps on MST

Add support for a fractional compressed link bpp on an MST link. Leave
the actual enabling of fractional bpps to a follow-up change.

While at it add an assert before the bpp loop, that the min and max bpps
are aligned to the bpp step. This should hold regardless of the non-DSC/DSC
or MST/UHBR-SST modes.

This keeps the mode validation and DSC->DPT BW specific maximum link
bpps as rounded-down integer values still, changing those to a
fractional value is left for later, add here TODO comments for them.

v2:
- Align the min/max bpp value to the bpp step.
- Assert that the min/max bpp values are aligned to the bpp step.

Subject: [PATCH 013/131] drm/i915: Add support for forcing the link bpp on a
 connector

Add support for forcing the link bpp on a connector via a connector
debugfs entry. During reducing link bpps due to a link BW limit, keep
bpps close to their forced value.

Add the debugfs entry to all relevant connectors: all DP connectors and
on an FDI link CRT/SDVO/LVDS/HDMI connectors.

v2:
- Move adding the debugfs entries to this patch.
- Rename i915_force_link_bpp to intel_force_link_bpp. (Jani)
- Select the relevant connectors via platform checks. (Jani)
- Use for_each_new_intel_connector_in_state(). (Jani)
- Fix 64 bit division vs. 32 bit build when converting str to q4. (lkp)
- Avoid division and addition overflow when converting str to q4.

v3:
- Add TODO: to make the non-DSC min bpp value connector specific. (Ankit)

Subject: [PATCH 014/131] drm/i915/dp_mst: Enable fractional link bpps on MST
 if the bpp is forced

Enable using a fractional (compressed) link bpp on MST links, if this is
supported and the link bpp is forced. Fractional link bpps will be
enabled by default as a follow-up change after testing this
functionality within a set of commonly used MST monitors and docks/hubs
which support it.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rewrite the VLV IOSF SB unit specific helpers in terms of the new
generic read/write functions. They become even simpler than they were.

The DPIO get/put helpers need to get/put both DPIO units.

v2: get/put both DPIO units

 functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We'll want to relocate the unit specific functions to display, making
them inaccessible to i915 core. As there aren't that many users in i915
core, we can just convert them to the generic VLV IOSF SB read/write
functions.

v2: Use BIT(unit) for get/put

Subject: [PATCH 019/131] drm/i915: move VLV IOSF SB unit specific helpers
 under display
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Now that all the VLV IOSF SB unit specific helper users are under
display, relocate the helpers themselves under display as
well. Resurrect the vlv_sideband.[ch] name for this. Make everything
except DPIO helpers static inlines, as their implementations are
trivial.

All of this considerably simplifies the xe compat header.

v2: Rebase

From bd4d1856f5fe427ad20d54c57bd0f2724f7be47e Mon Sep 17 00:00:00 2001
From: Jani Nikula <jani.nikula@intel.com>
Date: Mon, 12 May 2025 17:56:57 +0300
Subject: [PATCH 020/131] drm/i915: convert VLV IOSF SB interface to struct
 drm_device
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With users both in i915 core and display, struct drm_device is the
common denominator for the VLV IOSF SB users. Also use drm_device for
the helpers on the display side to keep the static inlines as simple as
possible.

We can drop a number of dependencies on i915_drv.h with this.

Subject: [PATCH 024/131] drm/i915/alpm: Stop writing ALPM registers when PSR
 is enabled
MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

Currently we are seeing these on PTL:

xe 0000:00:02.0: [drm] *ERROR* Timeout waiting for DDI BUF A to get active

These seem to be caused by writing ALPM registers while Panel Replay is
enabled.

Fix this by writing ALPM registers only when Panel Replay is about to be
enabled.

v4: improve comment on intel_psr_panel_replay_enable_sink call
v3: enable/disable ALPM from PSR code

 intel_display_conversion.h
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

All the PPS register users have been converted to struct
intel_display. The backward compat conversion to struct drm_i915_private
is no longer needed. Drop it, along with the include, and convert the
dev_priv macro parameter names to display while at it.

Subject: [PATCH 034/131] drm/{i915,xe}: convert i915 and xe display members
 into pointers

As the first step towards making struct intel_display an opaque pointer
in i915 and xe drivers, convert the struct drm_i915_private and struct
xe_device display members into pointers.

Initially, add temporary struct intel_display __display members, and
point display at it to avoid dynamic allocation. In the future, we can
drop this, and switch to dynamic allocation.

The conversion is done simply with sed:

sed -i 's/&\([a-zA-Z0-9_>.-]*\)\(dev_priv\|i915\|xe\)->display\([^.]\)/\1\2->display\3/g' \
    $(git ls-files -- drivers/gpu/drm/i915 drivers/gpu/drm/xe)

sed -i 's/\(dev_priv\|i915\|xe\)->display\./\1->display->/g' \
    $(git ls-files -- drivers/gpu/drm/i915 drivers/gpu/drm/xe)

With a couple of manual tweaks on top.

v2: Initialize i915->display also in selftest mock_gem_device()

Subject: [PATCH 035/131] drm/i915/dmc: Drop PIPEDMC faults from the fault mask
 on LNL+
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On LNL+ PIPEDMC faults are reported via PIPEDMC interrupts
instead of the direct DE_PIPE_* reporting used on earlier
platforms. Drop the relevant bits from the fault mask.

The bits are tied to zero on LNL, so there is no danger of
spurious fault interrupts even with an incorrect mask.

Subject: [PATCH 036/131] drm/i915/dmc: Hook up PIPEDMC interrupts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Hook up PIPEDMC interrupts. We'll need these for:
- flip queue signalling
- GTT/ATS faults on LNL+
- unclaimed register access errors (supposedly that is what
  the error interrupt indicated according to Windows code).

On LNL+ we get a new level of interrupts registers PIPEDMC_INTERRUPT*.
On earlier platforms we only have the INT_VECTOR field in the
PIPEDMC_STATUS registers, whose values are defined by the firmware.

For now we'll enable the interrupts on LNL+ only. For earlier platforms
it's not clear that there is any use for these interrupts, and some
ADL machines have exhibited spurious DE_PIPE interrupts with the
PIPEDMC interrupts unmasked/enabled. We can revisit enabling these
for earlier platforms in the future.

For some unknown reason LNL pipe B triggers the error interrupt
during the first DC state transition (subsequent transitions are
maybe OK?). No clear idea what's going on here yet, so keep the
error interrupt disabled for now.

Similar to DSB interrupt registers, the unused bits in
PIPEDMC_INTERRUPT* seem to act like randomg r/w bits (instead
of being hardwired to 0 like one would expect), and so we'll try
to avoid setting them so that we don't mistake them for real
interrupts.

v2: Only enable/unmask for LNL+
    Keep the flip queue interrupt masked off for now since
    we don't have a use for it yet
v3: Also keep the error interrupt masked off for now due to
    LNL pipe B triggering it

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We have two copies of the code to generate the "disable this event"
value for the DMC_EVT_CTL registers. Extract to a helper.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move is_dmc_evt_ctl_reg() to a slightly earlier position in the file
so that we can reuse it in the pkgc workaround code. Also move
is_dmc_evt_htp_reg() just to keep the two together.

Extract the helper to determine if the mmio reg+data are the
event handler register (DMC_EVT_CTL) for a specific event.
We'll have another use for this for runtime event handler
enable/disable.

Instead of hardcoding the event handler indices (for runtime
event handler enable/disable) we can simply look for the handler
with the appropriate event type. This isolates us from the firmware
details a bit better.

Subject: [PATCH 042/131] drm/i915/dsi: Enforce pipeline flush with DSI HS
 transfer

With all of the boundary conditions when streaming the commands B2B in our
validation (part of the reason we added the flush),  the Flush effectively
serializes the transmission of each command enqueued within the command
dispatcher to one per V. Blank line which simplifies the behavior of the
High Speed Arbitration.

So, unless we absolutely have to burst these to the Sink, we should be
using the Pipeline Flush bit to serialize the commands.

Subject: [PATCH 044/131] drm/i915/vrr: Program EMP_AS_SDP_TL for DP AS SDP
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The register EMP_AS_SDP_TL (MTL) was introduced for configuring the
double buffering point and transmission line for all
HDMI2.1 Extended Metadata Packets (VT-EMP for VRR, CVT-EMP for DSC etc).
This was also intended to be configured for DP to HDMI2.1 PCON to
support VRR.

From BMG and LNL+ onwards, this register was extended to Display Port
Adaptive Sync SDP to have a common register to configure double
buffering point and transmission line for both HDMI EMPs and DP VRR related
packets.

Currently, we do not support VRR for either native HDMI or via PCON.
However we need to configure this for DP SDP case. As per the spec,
program the register to set Vsync start as the double buffering point
for DP AS SDP.

v2:
-Make the helper more readable. (Jani)
-Add more information in commit message and comment.

Rename intel_dpll to intel_dpll_global so that intel_shared_dpll
can be renamed to intel_dpll in an effort to move away from the shared
naming convention.
Also intel_dpll according to it's comment tracks global dpll rather
than individual hence making more sense this gets changed.

starting MTL dpll's are not shared among PHYs.

Subject: [PATCH 047/131] drm/i915/dpll: Rename intel_shared_dpll_state

Rename intel_shared_dpll_state to just intel_dpll_state since it may
not necessarily store share dpll state info specially since
DISPLAY_VER >= 14 PLL's are not shared.
Also change the name of variables which may have been associated as
a shared_dpll.

Subject: [PATCH 049/131] drm/i915/dpll: Rename intel_shared_dpll_funcs

Rename intel_shared_dpll_funcs to intel_dpll_funcs
since it needs to represent both shared and individual
dplls.

--v2
-Change intel_global_dpll to intel_dpll_global to be more
in line with the naming standard where the name should
start with the file name [Jani]

--v3
-Drop shared and global altogether [Jani]

--v4
-Keep declarations sorted [Jani]

Subject: [PATCH 050/131] drm/i915/dpll: Rename intel_shared_dpll

Rename intel_shared_dpll to intel_dpll to represent both
shared and individual dplls. Since from MTL each PHY has it's
own PLL making the shared PLL naming a little outdated. In an
effort to make this framework accepting of future changes this
needs to be done.

--v2
-Use intel_dpll_global to make sure names start with the filename
[Jani/Ville]
-Explain the need of this rename [Jani]

--v3
-Just keep it intel_dpll [Jani]

--v4
-Fix comment [Jani]
-Use just num_dpll and dplls [Jani]

Subject: [PATCH 051/131] drm/i915/dpll: Move away from using shared dpll

Rename functions to move away from using shared dpll in the dpll
framework as much as possible since dpll may not always be shared.

--v2
-Use intel_dpll_global instead of global_dpll [Jani]

--v3
-Just use intel_dpll [Jani]

--v4
-Drop the global from comments [Jani]

Subject: [PATCH 052/131] drm/i915/dpll: Rename crtc_get_shared_dpll

Rename crtc_get_shared_dpll to take into the individual PLL framework
which came in at DISPLAY_VER >= 14.
Also having shared dpll stuff also in intel_dpll.c is just confusing.

--v2
-Change naming to dpll_global to keep consistency with rest of the
naming

--v3
-Just use intel_dpll [Jani]

--v4
-Modify commit message [Jani]

Subject: [PATCH 059/131] drm/i915/dp_mst: Work around Thunderbolt sink
 disconnect after SINK_COUNT_ESI read

Due to a problem in the iTBT DP-in adapter's firmware the sink on a TBT
link may get disconnected inadvertently if the SINK_COUNT_ESI and the
DP_LINK_SERVICE_IRQ_VECTOR_ESI0 registers are read in a single AUX
transaction. Work around the issue by reading these registers in
separate transactions.

The issue affects MTL+ platforms and will be fixed in the DP-in adapter
firmware, however releasing that firmware fix may take some time and is
not guaranteed to be available for all systems. Based on this apply the
workaround on affected platforms.

See HSD #13013007775.

Subject: [PATCH 064/131] drm/xe/display: move xe->display initialization to
 xe_display_probe()

The future goal is to have intel_display_device_probe() create struct
intel_display. As the first step, postpone xe->display initialization
right before that call. This is the same location as in i915.

There's a subtle functional change here: xe->display will now be
initialized only if xe->info.probe_display.

The xe_display_create() function becomes empty, and can be removed. Move
its documentation to xe_display_probe()

xe_display_driver_probe_defer() and xe_display_driver_set_hooks() get
called before either struct xe_device or struct intel_display

Subject: [PATCH 066/131] drm/xe/display: use xe->display to decide whether to
 do anything

Since we only initialize xe->display when xe->info.probe_display, we can
use !xe->display to bail out early. This seems cleaner and more accurate
than relying on xe->info.probe_display, since xe->display may indeed be
NULL.

Subject: [PATCH 067/131] drm/i915/dp: Fix the enabling/disabling of audio SDP
 splitting

Adjust the enabling/disabling steps of the DP audio SDP splitting
according to a recent Bspec update. This moves the enabling to the audio
codec enable sequence after the transcoder is enabled and disables SDP
splitting explicitly during the audio disable sequence.

Bspec requires waiting for a vblank event after the transcoder is
enabled and before SDP splitting is enabled. There is no need for an
explicit wait for this, since after the transcoder is enabled this
vblank event is guaranteed to have happened via a flip done wait (see
intel_atomic_commit_tail() -> drm_atomic_helper_wait_for_flip_done()).

The bspec update is for LNL+ only, but the HW team clarified that this
has been always the intended sequence on all platforms and bspec will be
updated everywhere accordingly.

The way SDP splitting was originally enabled matched the version of
bspec at that time. Adding here the Fixes: line still, since this
change fixes a FIFO underrun on PTL during output enabling when DSC is
enabled.

Bspec: 49283, 68943
Fixes: 8853750dbad8 ("drm/i915: Enable SDP split for DP2.0")

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add support for the new GOSUB DSB instruction (available on ptl+),
which instructs the DSB to jump to a different buffer, execute
the commands there, and then return execution to the next
instruction in the original buffer.

There are a few alignment related workarounds that need to
be dealt with when emitting GOSUB instruction.

v2: Right shift head and tail pointer passed to gosub command (chaitanya)
v3: Add macro for right shifting head/tail pointers (Animesh)
v4: Fix typo in commit message (Uma)
    Add comments explaining why right shifting htp is needed (Animesh)

A DSB buffer which will be used for GOSUB execution does not need
the DEWAKE mechanism but still need to be 64 bit aligned. Add helper
to finish preparation of a dsb buffer to be executed with GOSUB
instruction.

v2: Add a cacheline of noops at the end of GOSUB buffer (Ville)

With double buffer gamma registers in the mix, we need not wait for
vblank to execute gamma writes through dsb. Before we implement
that s/dsb_color_vblank/dsb_color.

Subject: [PATCH 076/131] drm/i915/display: use GOSUB to program double
 buffered LUT registers

With addition of double buffered GAMMA registers in PTL, we can now
program them in the active region. Use GOSUB instruction of DSB to
program them.

It is done in the following steps:
	1. intel_color_prepare_commit()
		- If the platform supports, prepare a dsb instance (dsb_color)
		  hooked to DSB0.
		- Add all the register write instructions to dsb_color through
		  the load_lut() hook
                - Do not add the vrr_send_push() logic to the buffer as it
		  should be taken care by dsb_commit instance of DSB0
                - Finish preparation of the buffer by aligning it to 64 bit

	2. intel_atomic_dsb_finish()
		- Add the gosub instruction into the dsb_commit instance of DSB0
		  using intel_dsb_gosub()
		- If needed, add the vrr_send_push() logic to dsb_commit after it

v2: Refactor code to simplify commit completion flow.
    Add some helpers along the way (Ville)
v3: s/doubled/double and add display to commit message prefix (Uma)

Subject: [PATCH 077/131] drm/i915: Program DB LUT registers before vblank

Double Buffered LUT registers can be programmed in the active region.
This patch implements the MMIO path for it. Program the registers after
evading vblank. The HW latches on to the registers after delayed vblank.
It takes around 1024 cdclk cycles(~one scanline) for this.

Following assumptions have been made while making this change

 - Current vblank evasion time is sufficient for programming
   the LUT registers.
 - Current guardband calculation would be sufficient for the HW
   to latch on to the new values

v2: move loading LUTs to commit_pipe_post_planes() since a vblank
    evasion failure for this is probably less drastic than
    for plane programming. (Ville)

Subject: [PATCH 081/131] drm/i915: stop including display/intel_display_{core,
 limits}.h from i915_drv.h

Make i915->display pointer opaque to most of core i915 driver. Lots of
places now need explicit include of intel_display_core.h, or a more
specific header.

With this dependency broken, changes in display should cause radically
less recompilation of i915.

Subject: [PATCH 082/131] drm/xe: stop including intel_display_{core, device}.h
 from xe_device_types.h

Make xe->display pointer opaque to most of core xe driver. A few places
now need explicit include of intel_display_core.h.

With this dependency broken, changes in display should cause radically
less recompilation of xe.

Subject: [PATCH 083/131] drm/i915: Indicate which pipe lied about its
 interrupts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Indicate which pipe signalled the spurious DE PIPE interrupt.
Might help with debugging a bit if we know where the interrupt
is supposedly coming from.

Subject: [PATCH 090/131] drm/i915/alpm: Add new interface to check if AUXLess
 ALPM is used
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

we need to know if AUXLess ALPM is used when preparing for link
training. Add new interface for this and use it in existing code where
possible.

v2: remove kerneldoc comment

Subject: [PATCH 097/131] drm/i915/display: Fix u32 overflow in SNPS PHY HDMI
 PLL setup

When configuring the HDMI PLL, calculations use DIV_ROUND_UP_ULL and
DIV_ROUND_DOWN_ULL macros, which internally rely on do_div. However, do_div
expects a 32-bit (u32) divisor, and at higher data rates, the divisor can
exceed this limit. This leads to incorrect division results and
ultimately misconfigured PLL values.
This fix replaces do_div calls with  div64_base64 calls where diviser
can exceed u32 limit.

Subject: [PATCH 102/131] drm/i915: add out_value to
 intel_wait_for_register_fw() and intel_de_wait_fw()

Future users of intel_de_wait_fw() need the final value. Just return it
for everyone using intel_wait_for_register_fw() and intel_de_wait_fw()
to avoid adding or using another set of specialized functions. There
aren't that many users for these anyway.

Subject: [PATCH 103/131] drm/i915/sbi: convert to intel_de_*()

Convert SBI to use the intel_de_*() interface. This allows us to drop
the dependency in i915_drv.h while at it.

The fast timeout for the status wait drops from 100 us to 2 us on i915,
but that should be of no consequence. The slow timeout remains the same.

Subject: [PATCH 105/131] drm/i915/sbi: clean up SBI register macro definitions
 and usage

Use REG_BIT() and friends for defining the register macros. Switch GVT
to use the same macros, and drop its own copies.

Subject: [PATCH 107/131] drm/i915/dram: add accessor for struct dram_info and
 use it

Add a function to get the (const) pointer to struct dram_info, and use
that to obtain the pointer instead of poking at i915->dram_info
directly.

Figure out the struct dram_info pointer in one place, and pass that
around to be filled in, instead of all places poking at i915->dram_info
directly.

Subject: [PATCH 110/131] drm/i915/dram: add return value and handling to
 intel_dram_detect()

We'll want to start returning errors from intel_dram_detect(). As the
first step, add the return value and error handling, even if we still
only return 0.

Do no functional changes, but leave a comment about whether we should
bail out on dram detection failures.

Subject: [PATCH 112/131] drm/i915/dkl: return if tc_port is invalid in
 dkl_phy_set_hip_idx()

In dkl_phy_set_hip_idx(), we may try to shift a value negatively,
whose behavior is undefined.  This can happen because we define
TC_PORT_NONE to -1, so theoretically tc_port could be -1.  We will
then use tc_port to shift to the correct address of the specified
port, but if it's negative, anything can happen.

If this happens or tc_port exceeds I915_MAX_TC_PORTS, it's safer to
return with a warning than risk an invalid write.

Subject: [PATCH 114/131] drm/i915: use drm_modeset_lock_assert_held() in
 intel_connector_get_pipe()

In the intel_connector_get_pipe() function, we check if
connection_mutex is held and generate our own WARN_ON if that's the
case.  Instead of generating a non-standard warning for a mutex issue,
we should use the standard lockdep framework.

Change the function to use drm_modeset_lock_assert_held() instead.

Subject: [PATCH 115/131] drm/i915: split out display register macros to a
 separate file
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is a scripted split of the display related register macros from
i915_reg.h to display/intel_display_regs.h. As a starting point, move
all the macros that are only used in display code (or GVT). If there are
users in core i915 code or soc/, or no users anywhere, keep the macros
in i915_reg.h. This is done in groups of macros separated by blank
lines, moving the comments along with the groups.

Some manually picked macro groups are kept/moved regardless of the
heuristics above.

This is obviously a very crude approach. It's not perfect. But there are
4.2k lines in i915_reg.h, and its refactoring has ground to a halt. This
is the big hammer that splits the file to two, and enables further
cleanup.

We cannot yet use xe->display to determine whether display hardware
has been successfully probed/initialized or not. This is because
xe->display would not be set to NULL even with GPUs with no display
capabilities (e.g, GMD_ID_DISPLAY = 0). However, this might change
in the future as Xe and i915 code is unified to deal with no display
cases.

Therefore, for now we have to continue to rely on xe->info.probe_display
(which would be set to false with display-less GPUs) to decide
whether to invoke any display related functions or not.

Subject: [PATCH 119/131] drm/dp: Change AUX DPCD probe address from DPCD_REV
 to LANE0_1_STATUS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reading DPCD registers has side-effects in general. In particular
accessing registers outside of the link training register range
(0x102-0x106, 0x202-0x207, 0x200c-0x200f, 0x2216) is explicitly
forbidden by the DP v2.1 Standard, see

3.6.5.1 DPTX AUX Transaction Handling Mandates
3.6.7.4 128b/132b DP Link Layer LTTPR Link Training Mandates

Based on my tests, accessing the DPCD_REV register during the link
training of an UHBR TBT DP tunnel sink leads to link training failures.

Solve the above by using the DP_LANE0_1_STATUS (0x202) register for the
DPCD register access quirk.

Subject: [PATCH 120/131] drm/edid: Define the quirks in an enum list

An enum list is better suited to define a quirk list, do that. This
makes looking up a quirk more robust and also allows for separating
quirks internal to the EDID parser and global quirks which can be
queried outside of the EDID parser (added as a follow-up).

Subject: [PATCH 121/131] drm/edid: Add support for quirks visible to DRM core
 and drivers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add support for EDID based quirks which can be queried outside of the
EDID parser iteself by DRM core and drivers. There are at least two such
quirks applicable to all drivers: the DPCD register access probe quirk
and the 128b/132b DPRX Lane Count Conversion quirk (see 3.5.2.16.3 in
the v2.1a DP Standard). The latter quirk applies to panels with specific
EDID panel names, support for defining a quirk this way will be added as
a follow-up.

v2: Reset global_quirks in drm_reset_display_info().
v3: (Jani)
- Use one list for both the global and internal quirks.
- Drop change for panel name specific quirks.
- Add comment about the way quirks should be queried.

Subject: [PATCH 122/131] drm/dp: Add an EDID quirk for the DPCD register
 access probe
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reading DPCD registers has side-effects and some of these can cause a
problem for instance during link training. Based on this it's better to
avoid the probing quirk done before each DPCD register read, limiting
this to the monitor which requires it. Add an EDID quirk for this. Leave
the quirk enabled by default, allowing it to be disabled after the
monitor is detected.

v2: Fix lockdep wrt. drm_dp_aux::hw_mutex when calling
    drm_dp_dpcd_set_probe_quirk() with a dependent lock already held.
v3: Add a helper for determining if DPCD probing is needed. (Jani)
v4:
- s/drm_dp_dpcd_set_probe_quirk/drm_dp_dpcd_set_probe (Jani)
- Fix documentation of drm_dp_dpcd_set_probe().
- Add comment at the end of internal quirk entries.

Subject: [PATCH 123/131] drm/i915/dp: Disable the AUX DPCD probe quirk if it's
 not required
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reading DPCD registers has side-effects and some of these can cause a
problem for instance during link training. Based on this it's better to
avoid the probing quirk done before each DPCD register read, limiting
this to the monitor which requires it. The only known problematic
monitor is an external SST sink, so keep the quirk disabled always for
eDP and MST sinks. Reenable the quirk after a hotplug event and after
resuming from a power state without hotplug support, until the
subsequent EDID based detection.

v2: Add a helper for determining the need/setting the probing. (Jani)

MIME-Version: 1.0

Windows code seems to do some dodgy looking +/-1 adjustments
to some of the vertical timings. Not sure if that's correct
or not, but let's at least cross check some of the values
we got from the hardware to double check whether the GOP
did the same or not.

Subject: [PATCH 126/131] drm/i915/dsb: Use intel_dsb_ins_align() in
 intel_dsb_align_tail()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If the free_post is not QW aligned we don't have to memset the
extra DW needed to make it so, as the only way that can happen
is via intel_dsb_reg_write_indexed() which already makes sure
the next DW is zeroed.

Not a big deal, but this is more consistent how all the other
stuff operates that puts instructions into the DSB buffer, and
we'll get a few more of those soon.

Pull the magic 20 usec DSB execution deadline into

for the non-arming register write section. For the non-arming
part we'll just throw in a random 80 usec for now so the total
is 100usec. The total exec time will be needed by the upcoming

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since the introduction of DSB chaining we no longer need the
DEwake tricks in intel_dsb_commit().

I also need to relocate the DSB_PMCTRL* writes out of
intel_dsb_finish() (due to the flip queue DMC vs. DSB register
corruption issues), and it'll be a bit more straightforward if
I don't have to worry about the non-chained DSB path anymore.

Subject: [PATCH 130/131] drm/i915/dsb: Move the DSB_PMCTRL* reset out of
 intel_dsb_finish()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When using the flip queue, due to the DMC vs. DSB register corruption
problem, we must not issue any register writes from the DSB after
unhalting the DMC. Currently we are doing just that by trying to
restore DSB_PMCTRL* back to a sane state from intel_dsb_finish().

Since the only place left that pokes at DSB_PMCTRL* is intel_dsb_chain()
we can just do DSB_PMCTRL_2/DSB_FORCE_DEWAKE reset in the same place.

The DSB_PMCTRL reset is trickier since we'd have to do it from the
chained DSB itself. But based on my earlier testing
DSB_PMCTRL/DSB_ENABLE_DEWAKE doesn't actually do anything if the DSB
isn't actually enabled, so we can omit the reset to keep things a bit
simpler. We do need to reset DSB_PMCTRL/DSB_ENABLE_DEWAKE before
tarting the DSB however, in case it was left enabled from a previous
use.

Subject: [PATCH 131/131] drm/i915/dsb: Disable the GOSUB interrupt
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Current DSB hardware is apparently a bit borked and likes to signal
spurious GOSUB errors. We already have most for the workarounds for
this in place, but the last part is simply not enabling the corresponding
interrupt.

While at it polish up the w/a comments with the w/a number,
and consistently take the short blurp from the w/a page.
