AUX power wells sometimes need additional handling besides just
programming the specific power well registers:
* Type-C PHY's also require additional Type-C register programming
* ICL combo PHY's require additional workarounds
* TGL & EHL combo PHY's can be treated like any other power well
Today we have dedicated aux ops for the ICL combo PHY and Type-C cases.
This works fine, but means that when a new platform shows up with
identical general power well handling, but different types of PHYs on
its outputs, we have to define an entire new power well table for that
platform and can't just re-use the table from the earlier platform -- as
an example, see ehl_power_wells[], which is a subset of
icl_power_wells[], *except* that we need to specify different AUX ops
for the third display.
If we instead create a single set of top-level aux ops that will check
the PHY type and then dispatch to the appropriate handlers, we can get
more reuse out of our power well definitions. This allows us to
immediately eliminate ehl_power_wells[] and simply reuse the ICL table;
if future platforms follow the same general power well assignments as
either ICL or TGL, we'll be able to re-use those tables in the same way.
Note that I've only changed ICL+ platforms over to using the new icl_aux
ops; at this point it's unlikely that we'll have any new platforms that
re-use gen9 or earlier power well configurations.
v2:
- ICL_AUX_PW_TO_PHY() won't return the proper PHY for TBT AUX power
wells. But we know those wells will only used on Type-C outputs
anyway, so we can just check is is_tc_tbt flag in the condition.

igt_ppgtt_pin_update() invokes i915_gem_context_get_vm_rcu(), which
returns a reference of the i915_address_space object to "vm" with
increased refcount.
When igt_ppgtt_pin_update() returns, "vm" becomes invalid, so the
refcount should be decreased to keep refcount balanced.
The reference counting issue happens in two exception handling paths of
igt_ppgtt_pin_update(). When i915_gem_object_create_internal() returns
IS_ERR, the refcnt increased by i915_gem_context_get_vm_rcu() is not
decreased, causing a refcnt leak.
Fix this issue by jumping to "out_vm" label when
i915_gem_object_create_internal() returns IS_ERR.

We shouldn't try to do link retraining from the short hpd handler.
We can't take any modeset locks there so this is racy as hell.
Push the whole thing into the hotplug work like we do with SST.
We'll just have to adjust the SST retraining code to deal with
the MST encoders and multiple pipes.
TODO: I have a feeling we should just rip this all out and
do a full modeset instead. Stuff like port sync and the tgl+
MST master transcoder stuff maybe doesn't work well if we
try to retrain without following the proper modeset sequence.
So far haven't done any actual tests to confirm that though.

Right now dp.regs.dp_tp_ctl/status are only set during the encoder
pre_enable() hook, what is causing all reads and writes to those
registers to go to offset 0x0 before pre_enable() is executed.
So if i915 takes the BIOS state and don't do a modeset any following
link retraing will fail.
In the case that i915 needs to do a modeset, the DDI disable sequence
will write to a wrong register not disabling DP 'Transport Enable' in
DP_TP_CTL, making a HDMI modeset in the same port/transcoder to
not light up the monitor.
So here for GENs older than 12, that have those registers fixed at
port offset range it is loading at encoder/port init while for GEN12
it will keep setting it at encoder pre_enable() and during HW state
readout.

This is required for legacy/static TC ports as IOM is not aware of

Just request PCODE to exit TCCOLD is not enough as it could enter
again before driver makes use of the port, to prevent it BSpec states
that aux powerwell should be held.
So here embedding the TC cold exit sequence into ICL aux enable,
it will enable aux and then request TC cold to exit.
The TC cold block(exit and aux hold) and unblock was added to some
exported TC functions for the others and to access PHY registers,
callers should enable and keep aux powerwell enabled during access.

when idle, we set the minimum frequency just in case there is some
residual current. Since the power curve should be a physical
relationship, if we find no power saving it's likely that we've broken

For certain DP VDSC bpp settings, hblank asserts before hblank_early,
leading to a bad audio state. Driver need to program "hblank early
enable" and "samples per line" parameters in AUDIO_CONFIG_BE
register.
This is Display Audio WA #1406928334 for 4k+VDSC usecase
applicable on DP encoders. Implemented the same.
v2: Fixed build failures on 32bit machine.
v3: Dropped u64, added helpers for sample room calculation,
other general comments as per Jani Nikula's feedback.
Also fixed connector type check (spotted by Anshuman)
v4: Addressed Jani Nikula and Kai's review comments.
v5: Addressed Anshuman's review comment and used crtc_* variable
to get timings.
v6: Dropped a redundant initialization.

Software is not expected to populate engine context except when using
restore inhibit bit or golden state to initialize it for the first time.
Therefore, if a newly submitted guest context is the same as the last
shadowed one, no need to populate its engine context from guest again.
Currently using lrca + ring_context_gpa to identify whether two guest
contexts are the same.
The reason of why context id is not included as an identifier is that
i915 recently changed the code and context id is only unique for a
context when OA is enabled. And when OA is on, context id is generated
based on lrca. Therefore, in that case, if two contexts are of the same
lrca, they have identical context ids as well.
(This patch also works with old guest kernel like 4.20.)
for guest context, if its ggtt entry is modified after last context
shadowing, it is also deemed as not the same context as last shadowed one.
v7:
-removed local variable "valid". use the one in s->last_ctx diretly
v6:
-change type of lrca of last ctx to be u32. as currently it's all
protected by vgpu lock (Kevin Tian)
-reset valid of last ctx to false once it needs to be repopulated before
population completes successfully (Kevin Tian)
v5:
-merge all 3 patches into one patch (Zhenyu Wang)
v4:
- split the series into 3 patches.
- don't turn on optimization until last patch in this series (Kevin Tian)
- define lrca to be atomic in this patch rather than update its type in
the second patch (Kevin Tian)
v3: updated commit message to describe engine context and context id
clearly (Kevin Tian)

platforms.
An initial version of state save and restore of AUD_FREQ_CNTRL register
was added for subset of platforms in commit 87c1694533
("drm/i915: save AUD_FREQ_CNTRL state at audio domain suspend"). The state
save has proven to work well and it is needed in newer platforms, so needs
to be extended. Although the logic is not in practise needed on GEN9/10
systems, follow the hardware specification and apply state and restore on
all gen9+ platforms.

Analogix_dp driver acquires all its resources in the ->bind() callback,
what is a bit against the component driver based approach, where the
driver initialization is split into a probe(), where all resources are
gathered, and a bind(), where all objects are created and a compound
driver is initialized.
Extract all the resource related operations to analogix_dp_probe() and
analogix_dp_remove(), then call them before/after registration of the
device components from the main Exynos DP and Rockchip DP drivers. Also
move the plat_data initialization to the probe() to make it available for
the analogix_dp_probe() function.
This fixes the multiple calls to the bind() of the DRM compound driver
when the DP PHY driver is not yet loaded/probed:

required binutils version to 2.21").
I confirmed the code in $(call as-instr,...) can be assembled by the
binutils 2.21 assembler and also by LLVM integrated assembler.

In cases where a clock table is malformed such that fclk entries have
frequencies but not voltages listed, we don't catch the error and set
clocks to 0 instead of using hardcoded values as we should.

[Why]
In some usecases, like tiled display, the stream and plane configuration
can be setup in a way where the caller expects DAL to perform the
clipping, eg:
P0:
src_rect(0, 0, w, h)
dst_rect(0, 0, w, h)
P1:
src_rect(w, 0, w, h)
dst_rect(0, 0, w, h)
Cursor is enabled on both streams with the same position.
This can result in double cursor on tiled display, even though this
behavior is technically correct from the DC interface point of view.
We need a mechanism to control this dynamically.
[How]
This is something that should live in the DM layer based on detection
of the specified configuration but it's not something that we really
have enough information to deal with today.
Add a flag to the cursor position state that specifies whether we
want DC to do the translation or not and make it opt-in and let
the DM decide when to do it.

[Why]
If a plane isn't being actively enabled or disabled then DC won't
always recalculate scaling rects and ratios for the primary plane.
This results in only a partial or corrupted rect being displayed on
the screen instead of scaling to fit the screen.
[How]
Add back the logic to recalculate the scaling rects into
dc_commit_updates_for_stream since this is the expected place to
do it in DC.
This was previously removed a few years ago to fix an underscan issue
but underscan is still functional now with this change - and it should
be, since this is only updating to the latest plane state getting passed
in.

For medium updates that change nothing but the source rect position

We're missing the check for the position update bit that was there in
the DCN10 hardware sequencer.
[How]
Check the position bit along with the scaling bit like we were doing
with DCN20.
We shouldn't actually hit a case where context != current_state in

[Why]
Cursor pos is correctly adjusted from DC side for source rect offset
on DCN ASIC, but only on the overlay.
This is because DM places offsets the cursor for primary planes only
to workaround missing code in DCE for the adjustment we're now correctly
doing in DC for DCN ASIC.
[How]
Drop the adjustment for source rect from the DM side of things and put
the code where it actually belongs - in DC on the pipe level.
This matches what we do for DCN now.

[Why]
Cursor is drawn as part of the framebuffer for a plane on AMD hardware.
The cursor position on the framebuffer does not change even if the
source rect viewport for the cursor does. This causes the cursor to be
clipped.
The following IGT tests fail as a result of this issue:
- kms_plane_cursor@pipe-*-viewport-size-*
[How]
Offset cursor position by plane source rect viewport. If the viewport
is unscaled then the cursor is now correctly positioned on any
plane - primary or overlay.
There is still a hardware limitation for dealing with the cursor size
being incorrectly scaled but that's not something we can address.
Add some documentation explaining some of this in the code while we're
at it.

If we find ourselves waiting on a MI_SEMAPHORE_WAIT, either within the
user batch or in our own preamble, the engine raises a
GT_WAIT_ON_SEMAPHORE interrupt. We can unmask that interrupt and so
respond to a semaphore wait by yielding the timeslice, if we have
another context to yield to!
The only real complication is that the interrupt is only generated for
the start of the semaphore wait, and is asynchronous to our
process_csb() -- that is, we may not have registered the timeslice before
we see the interrupt. To ensure we don't miss a potential semaphore
blocking forward progress (e.g. selftests/live_timeslice_preempt) we mark
the interrupt and apply it to the next timeslice regardless of whether it
was active at the time.
v2: We use semaphores in preempt-to-busy, within the timeslicing
implementation itself! Ergo, when we do insert a preemption due to an
expired timeslice, the new context may start with the missed semaphore
flagged by the retired context and be yielded, ad infinitum. To avoid
this, read the context id at the time of the semaphore interrupt and
only yield if that context is still active.

"nouveau 0000:01:00.0: can't change power state from D3cold to D0 (config

followed by backtraces of kernel crashes or timeouts within nouveau.

instead of addresses chosen by the core mm code. If start is greater than

svmm->unmanaged.limit which is greater than svmm->unmanaged.start and the
start = max_t(u64, start, svmm->unmanaged.limit) will change nothing.

If we want to percolate information back from the HW, up through the GEM
context, we need to wait until the intel_context is scheduled out for
the last time. This is handled by the retirement of the intel_context's
barrier, i.e. by listening to the pulse after the notional unpin. So
wait until the intel_context is finally retired before releasing the
engine, so that we can inspect the final context state and pass it on.
