The Winstar wf40eswaa6mnn0 panel is a square 4.0" TFT LCD with a
resolution of 480x480 pixels.
This panel is driven by the Sitronix ST7701 controller and uses a MIPI
DSI interface. The settings are based on the panel's datasheet and the
init sequence provided by Winstar.
It was tested on a Verdin iMX8MP from Toradex with a Carrier Board
providing a MIPI DSI interface.

`vc4_hdmi_audio_init` calls `devm_snd_dmaengine_pcm_register` which may
return EPROBE_DEFER. Calling `drm_connector_hdmi_audio_init` adds a
child device. The driver model docs[1] state that adding a child device
prior to returning EPROBE_DEFER may result in an infinite loop.

If we have a newer dtb than kernel, we could end up in a situation where
the GPU device is present in the dtb, but not in the drivers device
table. We don't want this to prevent the display from probing. So

The files generated by gen_header.py capture the source path to the

based on where and when the kernel was built as the full path is
captured.
Since all of the files that this tool is run on is under the drivers

drivers. Additionally it prints <stripped> instead of the date.

Calling this packet is necessary when we switch contexts because there
are various pieces of state used by userspace to synchronize between BR
and BV that are persistent across submits and we need to make sure that
they are in a "safe" state when switching contexts. Otherwise a
userspace submission in one context could cause another context to
function incorrectly and hang, effectively a denial of service (although
without leaking data). This was missed during initial a7xx bringup.

When things go wrong, the GPU is capable of quickly generating millions
of faulting translation requests per second. When that happens, in the
stall-on-fault model each access will stall until it wins the race to
signal the fault and then the RESUME register is written. This slows
processing page faults to a crawl as the GPU can generate faults much
faster than the CPU can acknowledge them. It also means that all
available resources in the SMMU are saturated waiting for the stalled
transactions, so that other transactions such as transactions generated
by the GMU, which shares translation resources with the GPU, cannot
proceed. This causes a GMU watchdog timeout, which leads to a failed
reset because GX cannot collapse when there is a transaction pending and
a permanently hung GPU.
On older platforms with qcom,smmu-v2, it seems that when one transaction
is stalled subsequent faulting transactions are terminated, which avoids
this problem, but the MMU-500 follows the spec here.
To work around these problems, disable stall-on-fault as soon as we get a
page fault until a cooldown period after pagefaults stop. This allows
the GMU some guaranteed time to continue working. We only use
stall-on-fault to halt the GPU while we collect a devcoredump and we
always terminate the transaction afterward, so it's fine to miss some
subsequent page faults. We also keep it disabled so long as the current
devcoredump hasn't been deleted, because in that case we likely won't
capture another one if there's a fault.
After this commit HFI messages still occasionally time out, because the
crashdump handler doesn't run fast enough to let the GMU resume, but the
driver seems to recover from it. This will probably go away after the
HFI timeout is increased.

On old Intel platforms, the size of the GSM (i.e., the stolen memory
that holds the GGTT page table entries) could vary, so the driver needed
to read the actual size from the PCI config space. However from Xe_HP
onward, the GSM is now always guaranteed to be exactly 8MB (which
translates to a 4GB GGTT address space); this is always true regardless
of what the platform's much larger PPGTT address space is.
The bspec doesn't document the PCI config space as being a valid way to
query the size of the GSM after Xe_LP platforms, although so far it
still seems to be giving us proper values for Xe_HP, Xe2, and Xe3.
However we suspect that the config space will stop providing correct
values on some upcoming platforms, so we should stop relying on it.
Instead just use the hardcoded 8MB value as documented elsewhere in the
bspec.

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.

Driver unconditionally saves current state on first init in
dsi_pll_10nm_init(), but does not save the VCO rate, only some of the
divider registers. The state is then restored during probe/enable via
msm_dsi_phy_enable() -> msm_dsi_phy_pll_restore_state() ->
dsi_10nm_pll_restore_state().
Restoring calls dsi_pll_10nm_vco_set_rate() with
pll_10nm->vco_current_rate=0, which basically overwrites existing rate of
VCO and messes with clock hierarchy, by setting frequency to 0 to clock
tree. This makes anyway little sense - VCO rate was not saved, so
should not be restored.
If PLL was not configured configure it to minimum rate to avoid glitches
and configuring entire in clock hierarchy to 0 Hz.

that it is only supported on DPU 5.0.0 onwards which includes SC7180 on
DPU revision 6.2. However, this patch missed that the description
structure for SC7180 is also reused for SDM845 (because of identical
io_start address) which is only DPU 4.0.0, leading to a wrongly enbled
widebus feature and corruption on that platform.
Create a separate msm_dp_desc_sdm845 structure for this SoC compatible,
with the wide_bus_supported flag turned off.

The GuC compatibility version that we read from the CSS header in
native/PF and the GuC VF version that we get when a VF handshakes with
the GuC are the same version number, so we should store it into the same
structure. This makes all the checks based on the compatibility version
automatically work for VFs without having to copy the value over.
For completion, also copy the wanted version and set the path to a known
string to indicate that the FW is PF-loaded. This way all the info will
be coherent when dumped from debugfs.
v2: several code cleanups and style changes (Michal), rebase on
bootstrap changes.
v3: s/min/wanted/, clarify that handshake must happen before we can get
the VF versions (Michal)

Instead of using a VF-specific type, we can use the common uc_fw_version
structure. This also means that we can use the available macros to
compare ABI versions.
While at it, exit early from the bootstrap if this is not the first time
we're doing it and the version hasn't changed, so we don't end up
logging it multiple times.

Currently we perform the bootstrap for the primary GT early on during
device init, while the media GT bootstrap happens when we try and fetch
the hwconfig table. For consistency, move the bootstrap of the media GT
happen at the same time as the primary GT, so that all the subsequent
code can rely on both GTs being in the same state.
v2: Also drop config query from min_guc_load since we now do it
early (Michal)

The VF ABI version has a branch field, so to store it inside the
uc_fw_version we need to add a new branch variable to the latter.
Existing code needs to be updated to handle the fact that we have the
new field.
v2: split out to its own patch (Michal)
