The same parade TCON issue can potentially happen on Phoenix, and the same
PSR resilience changes have been ported into the DMUB firmware.
Don't allow running PSR-SU unless on the newer firmware.

A number of parade TCONs are causing system hangs when utilized with
older DMUB firmware and PSR-SU. Some changes have been introduced into
DMUB firmware to add resilience against these failures.
Don't allow running PSR-SU unless on the newer firmware.

The `DMUB_FW_VERSION` macro has a mistake in that the revision field
is off by one byte. The last byte is typically used for other purposes

[Why]
This display doesn't properly indicate link loss through DPCD bits such
as CR_DONE / CHANNEL_EQ_DONE / SYMBOL_LOCKED / INTERLANE_ALIGN_DONE,
which all remain set.
In addition, DPCD200Eh doesn't match the value of DPCD204h in all cases.
For these reasons, we can miss re-training the link, since we don't
properly detect link loss with this display.
[Why]
Add display-specific workaround to read DPCD204h, so that we can detect
link loss based on 128b132b-specific status bits in this register.

For GFX 9.4.3, interrupt handling needs to be updated for:
- Interrupt cookie will have a NodeId field. Each KFD
node needs to check the NodeId before processing the
interrupt.
- For CPX mode, there are additional checks of client ID
needed to process the interrupt.
- Add NodeId to the process drain interrupt.

Currently, it is possible for us to access memory that we shouldn't.
Since, we acquire (possibly dangling) pointers to dirty rectangles
before doing a bounds check to make sure we can actually accommodate the
number of dirty rectangles userspace has requested to fill. This issue
is especially evident if a compositor requests both MPO and damage clips
at the same time, in which case I have observed a soft-hang. So, to
avoid this issue, perform the bounds check before filling a single dirty
rectangle and WARN() about it, if it is ever attempted in
fill_dc_dirty_rect().

A number of users have reported that there are random hangs occurring
caused by PSR-SU specifically on panels that contain the parade 0803
TCON. Users have been able to work around the issue by disabling PSR
entirely.
To avoid these hangs, disable PSR-SU when this TCON is found.

For pid namespaces, struct pid uses a dynamically sized array member,
"numbers". This was implemented using the ancient 1-element fake
flexible array, which has been deprecated for decades.
Replace it with a C99 flexible array, refactor the array size
calculations to use struct_size(), and address elements via indexes.
Note that the static initializer (which defines a single element) works
as-is, and requires no special handling.
Without this, CONFIG_UBSAN_BOUNDS (and potentially
CONFIG_FORTIFY_SOURCE) will trigger bounds checks:

The main kdb command parser only handles CR (ASCII 13 AKA '\r') today,
but not LF (ASCII 10 AKA '\n'). That means that the kdb command parser
can handle terminals that send just CR or that send CR+LF but can't
handle terminals that send just LF.
The fact that kdb didn't handle LF in the command parser tripped up a
tool I tried to use with it. Specifically, I was trying to send a
command to my device to resume it from kdb using a ChromeOS tool like:
dut-control cpu_uart_cmd:"g"
That tool only terminates lines with LF, not CR+LF.
Arguably the ChromeOS tool should be fixed. After all, officially kdb
seems to be designed such that CR+LF is the official line ending
transmitted over the wire and that internally a line ending is just
'\n' (LF). Some evidence:
* uart_poll_put_char(), which is used by kdb, notices a '\n' and
converts it to '\r\n'.
* kdb functions specifically use '\r' to get a carriage return without
a newline. You can see this in the pager where kdb will write a '\r'
and then write over the pager prompt.
However, all that being said there's no real harm in accepting LF as a
command terminator in the kdb parser and doing so seems like it would
improve compatibility. After this, I'd expect that things would work
OK-ish with a remote terminal that used any of CR, CR+LF, or LF as a
line ending. Someone using CR as a line ending might get some ugliness
where kdb wasn't able to overwrite the last line, but basic commands
would work. Someone using just LF as a line ending would probably also
work OK.
A few other notes:
- It can be noted that "bash" running on an "agetty" handles LF as a
line termination with no complaints.
- Historically, kdb's "pager" actually handled either CR or LF fine. A
very quick inspection would make one think that kdb's pager actually
could have paged down two lines instead of one for anyone using
CR+LF, but this is generally avoided because of kdb_input_flush().
- Conceivably one could argue that some of this special case logic
belongs in uart_poll_get_char() since uart_poll_put_char() handles
the '\n' => '\r\n' conversion. I would argue that perhaps we should
eventually do the opposite and move the '\n' => '\r\n' out of
uart_poll_put_char(). Having that conversion at such a low level
could interfere if we ever want to transfer binary data. In
addition, if we truly made uart_poll_get_char() the inverse of
uart_poll_put_char() it would convert back to '\n' and (ironically)
kdb's parser currently only looks for '\r' to find the end of a
command.
