what will be executed again in intel_update_crtc() over port sync

If it is really necessary at least it deserves a better name and a

needs to do a modeset.

implemented.
The MST disable sequence is basically the same for HSW, SKL, ICL and
TGL, with just minor changes for TGL.
With this last patch we finally fixed the hotplugs triggered by MST
sinks during the disable/enable sequence, those were causing source
to try to do a link training while it was not ready causing CPU pipe
FIFO underrrus on TGL.

Due to DDB overlaps the pipe enabling sequence is not always crescent.
As the previous patch selects the smallest pipe/transcoder in the MST
stream to be master and it needs to be enabled first, this changes
were needed to guarantee that.
So first lets enable all pipes that do not need a fullmodeset as
those don't have any external dependency and those are the ones that
can overlap with each other.
Then on the second loop it will enable all the pipes that needs a
modeset and don't depends on other pipes like MST master
pipe/transcoder.
Then finally all the pipes that needs a modeset and have dependency
on other pipes, that at this point are alread enabled.
v3: rebased
v4:
- added check for modeset_pipes too to decide if is necessary for a
wait a vblank
- added DDB allocation overlap check for pipes that needs a modeset

On TGL the blending of all the streams have moved from DDI to
transcoder, so now every transcoder working over the same MST port must
send its stream to a master transcoder and master will send to DDI
respecting the time slots.
So here adding all the CRTCs that shares the same MST stream if
needed and computing their state again, it will pick the lowest
pipe/transcoder among the ones in the same stream to be master.
Most of the time skl_commit_modeset_enables() enables pipes in a
crescent order but due DDB overlapping it might not happen, this
scenarios will be handled in the next patch.
v2:
- Using recently added intel_crtc_state_reset() to set
mst_master_transcoder to invalid transcoder for all non gen12 & MST
code paths
- Setting lowest pipe/transcoder as master, previously it was the
first one but setting a predictable one will help in future MST e
port sync integration
- Moving to intel type as much as we can
v3:
- Now intel_dp_mst_master_trans_compute() returns the MST master transcoder
- Replaced stdbool.h by linux/types.h
- Skip the connector being checked in
intel_dp_mst_atomic_master_trans_check()
- Using pipe instead of transcoder to compute MST master
v4:
- renamed connector_state to conn_state
v5:
- Improved the parameters of intel_dp_mst_master_trans_compute() to
simply code
- Added call drm_atomic_add_affected_planes() in
intel_dp_mst_atomic_master_trans_check() as helper could not do it

Gen-12 display decompression operates on Y-tiled compressed main surface.
The CCS is linear and has 4 bits of metadata for each main surface cache
line pair, a size ratio of 1:256. Gen-12 display decompression is
incompatible with buffers compressed by earlier GPUs, so make use of a new
modifier to identify gen-12 compression. Another notable change is that
render decompression is supported on all planes except cursor and on all

of CCS plane can be different based on the format (packed vs. YUV

Move all of haswell_crtc_disable() into the encoder
.post_disable() hooks. Now we're left with just
calling the .disable() and .post_disable() hooks
back to back.
I chose to move the code into the .post_disable() hook instead
of the .disable() hook as most of the sequence is currently
implemented in the .post_disable() hook.
We should collapse it all down to just one hook and then the
encoders can drive the modeset sequence fully. But that may
need some further refactoring as we currently call the
ddi .post_disable() hook from mst code and we can't just
replace that with a call to the ddi .disable() hook.
Should also follow up with similar treatment for the enable
sequence but let's start here where it's easier.

At least Bay Trail (BYT) and Cherry Trail (CHT) devices can use 1 of 2
different PWM controllers for controlling the LCD's backlight brightness.
Either the one integrated into the PMIC or the one integrated into the
SoC (the 1st LPSS PWM controller).
So far in the LPSS code on BYT we have skipped registering the LPSS PWM
controller "pwm_backlight" lookup entry when a Crystal Cove PMIC is
present, assuming that in this case the PMIC PWM controller will be used.
On CHT we have been relying on only 1 of the 2 PWM controllers being
enabled in the DSDT at the same time; and always registered the lookup.
So far this has been working, but the correct way to determine which PWM
controller needs to be used is by checking a bit in the VBT table and
recently I've learned about 2 different BYT devices:
Point of View MOBII TAB-P800W
Acer Switch 10 SW5-012
Which use a Crystal Cove PMIC, yet the LCD is connected to the SoC/LPSS
PWM controller (and the VBT correctly indicates this), so here our old
heuristics fail.
This commit fixes using the wrong PWM controller on these devices by
calling pwm_get() for the right PWM controller based on the
VBT dsi.config.pwm_blc bit.
Note this is part of a series which contains 2 other patches which renames
the PWM lookup for the 1st SoC/LPSS PWM from "pwm_backlight" to
"pwm_pmic_backlight" and the PWM lookup for the Crystal Cove PMIC PWM
from "pwm_backlight" to "pwm_pmic_backlight".

According to both the old acpi_igd_opregion_spec_0.pdf and the newer
skl_opregion_rev0p5.pdf opregion specification documents, if a driver
handles hotplug events itself, it should set the opregion CHPD field to
1 to indicate this and the firmware should respond to this by no longer
sending ACPI 0x00 notification events on e.g. lid-state changes.
Specifically skl_opregion_rev0p5.pdf states thid in the documentation of
the CHPD word: "Re-enumeration trigger logic in System BIOS MUST be
disabled for all the Operating Systems supporting Hot-Plug
(e.g., Windows* Longhorn and above)." Note the MUST in there.
We ignore these notifications, so this should not be a problem but many
recent DSTDs seem to all have the same copy-pasted bug in the GNOT() AML
function which is used to send these notifications. Windows likely does not
hit this bug as it presumably correcty sets CHPD to 1.
Here is an example of the broken GNOT() method:
Method (GNOT, 2, NotSerialized)
{
...
CEVT = Arg0
CSTS = 0x03
If (((CHPD == Zero) && (Arg1 == Zero)))
{
If (((OSYS > 0x07D0) || (OSYS < 0x07D6)))
{
Notify (PCI0, Arg1)
}
Else
{
Notify (GFX0, Arg1)
}
}
...
Notice that the condition for the If is always true I believe that the
|| like needs to be an &&, but there is nothing we can do about this and
in my own DSDT archive 55 of the 93 DSDTs have this issue.
When the if is true the notification gets send to the PCI root instead
of only to the GFX0 device. This causes Linux to re-enumerate PCI devices
whenever the LID opens / closes, leading to unexpected messages in dmesg:
Suspend through lid close:

And more importantly this re-enumeration races with suspend/resume causing
enumeration to not be complete when assert_isp_power_gated() from
drivers/gpu/drm/i915/display/intel_display_power.c runs. This causes
the !pci_dev_present(isp_ids) check in assert_isp_power_gated() to fail
making the condition for the WARN true, leading to:

This commit fixes the unwanted ACPI notification on the PCI root device
by setting CHPD to 1, so that the broken if condition in the AML never
gets checked as notifications of type 0x00 are disabled altogether.

Outputs C and D on EHL are combo PHY outputs and thus should not be
using the same TC AUX power well handlers as ICL. And even though
icl_combo_phy_aux_power_well_ops works okay for EHL/JSL combo PHYs none
of its special handling is actually necessary for this platform:
* EHL/JSL don't actually need to program PORT_CL_DW12
* Display WA #1178 does not apply to EHL/JSL
Thus we can simply drop back to using our standard "hsw-style" power

In order to eliminate intel_pipe_to_cpu_transcoder() (and its
crtc->config usage) let's pass the cpu transcoder to
assert_pipe() so we don't have to do the pipe->cpu transcoder
lookup on HSW+.
On VLV/CHV this can get called during eDP init, which
happens before crtc->config->cpu_transcoder is even
populated. So currently we're always reading PIPECONF(A)

Let's start to eliminate intel_pipe_to_cpu_transcoder() so that
we can get rid of one more crtc->config usage (which we will want
to nuke as well).
In the case of assert_fdi_tx() we know that we're never
dealing with the EDP transcoder so we can simply replace
this with a cast.

We don't want to use the FBC hardware render tracking so let's not

integrate this into the command submissing path as the register is
context saved, and if rendering happens via the ppgtt we'd have
to configure it with the ppgtt address instead of the ggtt address.
Easier to use software tracking instead.
Note that on pre-ilk we can't actually disable render tracking.
However we can't rely on it because it requires that DSPSURF to
match the render target address, and since we play tricks
with DSPSURF that may not be the case. Hence we shall rely on
software render tracking on all platforms.

Commit 9c722e17c1 ("drm/i915: Disable pipes in reverse order")
reverted the order that pipes gets disabled because of TGL
master/slave relationship between transcoders in MST mode.
But as stated in a comment in skl_commit_modeset_enables() the
enabling order is not always crescent, possibly causing previously
selected slave transcoder being enabled before master so another
approach will be needed to select a transcoder to master in MST mode.
It will be similar to the approach taken in port sync.
But instead of implement something like
intel_trans_port_sync_modeset_disables() to MST lets simply it and
iterate over all pipes 2 times, the first one disabling any slave and
then disabling everything else.
The MST bits will be added in another patch.
v2:
Not using crtc->active as it is deprecated
v3:
Removing is_trans_port_sync_mode() check, just check for
is_trans_port_sync_master() is enough
v4:
Adding and using is_trans_port_sync_slave(), otherwise non-port sync
pipes will be disabled in the first loop, what is not wrong but is
not what patch description promises

Assuming intel_crtc_arm_fifo_underrun() only gets called when
there's no pending plane updates we can utilize it on gen2 by
checking the active_planes bitmask so that we only re-enable
underrun reporting if some planes are active.
i915_fifo_underrun_reset_write() seems to have the necessary
hw_done/flip_done waits in place.

Let's just inline intel_pre_disable_primary_noatomic() into
intel_plane_disable_noatomic(). The CxSR disable we can do
regardless of which plane we're disabling, and while at it we can
make the gen2 underrun w/a accurate by consulting the active_planes
bitmask.

We have the active_planes bitmask now so use it to properly
determine when some planes are visible for the gen2 underrun
workaround.
This let's us almost eliminate intel_post_enable_primary().
The manual underrun checks we can simply move into
intel_atomic_commit_tail() since they loop over all the pipes
already. No point in repeating the checks multiple times when
there are multiple pipes in the commit.

Change the calling convention to just pass the state+crtc and
switch to intel_ types throughout.
We'll also do a quick s/if (old_primary_state)/if (new_primary_state)/
so that we'll be able to eliminate old_primary_state later. This
is fine since we always have either both old and new state or neither.
