cd6b1674d6 docs: Fix botched rST conversion of 'submitting-a-patch.rst'
I completely botched up the merged[0] rST conversion of this document by
accidentally dropping entire hunks (!) of text. :-(  I made it very hard
for reviewers to spot it, as the omitted text was buried deep in the
document.  To fix my hatchet job, I reconverted the "SubmitAPatch"
wiki[1] page from scratch and replaced the existing rST with it, while
making sure I incorporated previous feedback.

In summary, in this reconverted edition:

- I did a careful (to the extent my eyes allowed) para-by-para
  comparison of the wiki and the rST to make sure I didn't omit
  anything accidentally.

- I made sure to work in the cosmetic feedback[2] that Thomas Huth
  pointed out in the merged (and botched) edition:

   - fix the hyperlinks in "Split up long patches"

   - replace ".". with "does not end with a dot" (in "Write a meaningful
     commit message" section)

   - replace "---" with ``---`` so that it doesn't render as an em-dash
     (there were two other occurrences; I fixed those too)

- Use "QEMU" spelling consistently in prose usage

- Add a consistent "refer to git-config" link where appropriate

Thanks to Thomas Huth and Alex Bennée for noticing it on IRC.  And sorry
for my sloppiness.

319e89cdc3 escc: update the R_SPEC register SPEC_ALLSENT bit when writing to W_TXCTRL1
The ESCC datasheet states that SPEC_ALLSENT is always set in sync mode and set
in async mode once all characters have cleared the transmitter. Since writes to
SERIAL_DATA use a synchronous chardev API, the guest can never see the state when
transmission is in progress so it is possible to set SPEC_ALLSENT in the
R_SPEC register unconditionally.

This fixes a hang when using the Sun PROM as it attempts to enumerate the
onboard serial devices, and a similar hang in OpenBSD SPARC32 where in both cases
the boot process will not proceed until SPEC_ALLSENT has been set after writing
to W_TXCTRL1.

c29cd47e82 escc: always set STATUS_TXEMPTY in R_STATUS on device reset
The "Transmit Interrupts and Transmit Buffer Empty Bit" section of the ESCC
datasheet states the following about the STATUS_TXEMPTY bit: "After a hardware
reset (including a hardware reset by software), or a channel reset, this bit
is set to 1".

Update escc_reset() to set the STATUS_TXEMPTY bit in the R_STATUS register
on device reset as described which fixes a regression whereby the Sun PROM
checks this bit early on startup and gets stuck in an infinite loop if it is
not set.

fbab8cc24d meson.build: Support ncurses on MacOS and OpenBSD
MacOS provides header files for curses 5.7 with support
for wide characters, but requires _XOPEN_SOURCE_EXTENDED=1
to activate that.

By default those old header files are used even if there
is a newer Homebrew installation of ncurses 6.2 available.

Change also the old macro definition of NCURSES_WIDECHAR
and set it to 1 like it is done in newer versions of
curses.h when _XOPEN_SOURCE_EXTENDED=1 is defined.

OpenBSD has the same version of ncurses and needs the same fix.

Add property for requesting AMD SEV measured kernel launch

 - The 'sev-guest' object gains a boolean 'kernel-hashes' property
   which must be enabled to request a measured kernel launch.

a0190bf150 target/i386/sev: Fail when invalid hashes table area detected
Commit cff03145ed ("sev/i386: Introduce sev_add_kernel_loader_hashes
for measured linux boot", 2021-09-30) introduced measured direct boot
with -kernel, using an OVMF-designated hashes table which QEMU fills.

However, no checks are performed on the validity of the hashes area
designated by OVMF.  Specifically, if OVMF publishes the
SEV_HASH_TABLE_RV_GUID entry but it is filled with zeroes, this will
cause QEMU to write the hashes entries over the first page of the
guest's memory (GPA 0).

Add validity checks to the published area.  If the hashes table area's
base address is zero, or its size is too small to fit the aligned hashes
table, display an error and stop the guest launch.  In such case, the
following error will be displayed:

    qemu-system-x86_64: SEV: guest firmware hashes table area is invalid (base=0x0 size=0x0)

9dbe0c93f0 target/i386/sev: Add kernel hashes only if sev-guest.kernel-hashes=on
Commit cff03145ed ("sev/i386: Introduce sev_add_kernel_loader_hashes
for measured linux boot", 2021-09-30) introduced measured direct boot
with -kernel, using an OVMF-designated hashes table which QEMU fills.

However, if OVMF doesn't designate such an area, QEMU would completely
abort the VM launch.  This breaks launching with -kernel using older
OVMF images which don't publish the SEV_HASH_TABLE_RV_GUID.

Fix that so QEMU will only look for the hashes table if the sev-guest
kernel-hashes option is set to on.  Otherwise, QEMU won't look for the
designated area in OVMF and won't fill that area.

To enable addition of kernel hashes, launch the guest with:

    -object sev-guest,...,kernel-hashes=on

d06f3bf922 gitlab-ci/cirrus: Increase timeout to 80 minutes
The jobs on Cirrus-CI sometimes get delayed quite a bit, waiting to
be scheduled, so while the build test itself finishes within 60 minutes,
the total run time of the jobs can be longer due to this waiting time.
Thus let's increase the timeout on the gitlab side a little bit, so
that these jobs are not marked as failing just because of the delay.

This reverts commit ca89d15f8e.

There is already an entry for this kind of messages earlier in the
ERROR_RULE_LIST - when I added this patch, I just got fooled by
the other errors that occur due to a race between QMP connection
and QEMU terminating early (which still spit out the 'No bus found'
messages in their backtrace), but these other problems have now
fortunately been tackled by John Snow, so we certainly don't need
this duplicated entry here anymore.

c398a241ec scripts/device-crash-test: hide tracebacks for QMP connect errors
Generally, the traceback for a connection failure is uninteresting and
all we need to know is that the connection attempt failed.

Reduce the verbosity in these cases, except when debugging.

76f86e78b2 scripts/device-crash-test: don't emit AQMP connection errors to stdout
These errors are expected, so they shouldn't clog up terminal output. In
the event that they're *not* expected, we'll be seeing an awful lot more
output concerning the nature of the failure.

47b43acd57 scripts/device-crash-test: simplify Exception handling
We don't need to handle KeyboardInterruptError specifically; we can
instead tighten the scope of the broad Exception handlers to only catch
"Exception", which has the effect of allowing all BaseException classes
that do not inherit from Exception to be raised through.

KeyboardInterruptError and a few other important ones are
BaseExceptions, so this does the same thing with less code.

25de7f5012 python/aqmp: fix ConnectError string method
When ConnectError is used to wrap an Exception that was initialized
without an error message, we are treated to a traceback with a rubbish
line like this:

... ConnectError: Failed to establish session:

Correct this to use the name of an exception as a fallback message:

... ConnectError: Failed to establish session: EOFError

Better!

f26bd6ff21 python/aqmp: Fix disconnect during capabilities negotiation
If we receive ConnectionResetError (ECONNRESET) while attempting to
perform capabilities negotiation -- prior to the establishment of the
async reader/writer tasks -- the disconnect function is not aware that
we are in an error pathway.

As a result, when attempting to close the StreamWriter, we'll see the
same ConnectionResetError that caused us to initiate a disconnect in the
first place, which will cause the disconnect task itself to fail, which
emits a CRITICAL logging event.

I still don't know if there's a smarter way to check to see if an
exception received at this point is "the same" exception as the one that
caused the initial disconnect, but for now the problem can be avoided by
improving the error pathway detection in the exit path.
