To work correctly -dump-vmstate and vmstate-static-checker.py need to
dump all the supported vmstates.
But as some devices can be modules, they are not loaded at startup and not
dumped. Fix that by loading all available modules before dumping the
machine vmstate.

vnc_server_cut_text_caps() is not guaranteed to be called only once.
If it called twice, we finally call notifier_list_add() twice with same
element. Which leads to loopback QLIST. So, on next
notifier_list_notify() we'll loop forever and QEMU stuck.
So, let's only register new notifier if it's not yet registered.
Note, that similar check is used in vdagent_chr_recv_caps() (before
call qemu_clipboard_peer_register()), and also before
qemu_clipboard_peer_unregister() call in vdagent_disconnect() and in
vnc_disconnect_finish().

The dmabuf often becomes invalid right after unblocking pipeline
and graphic_hw_gl_flushed in case a new scanout blob is submitted
because the dmabuf associated with the current guest scanout is
freed after swapping.
So both graphic_hw_gl_block and graphic_hw_gl_flushed should be
executed after closing fence_fd for the current dmabuf.

Configuring a drive with "if=none" is meant for creation of a backend
only, it should not get automatically assigned to a device frontend.
Use "if=pflash" for the One-Time-Programmable device instead (like
it is e.g. also done for the efuse device in hw/arm/xlnx-zcu102.c).
Since the old way of configuring the device has already been published
with the previous QEMU versions, we cannot remove this immediately, but
have to deprecate it and support it for at least two more releases.

escc: update the R_SPEC register SPEC_ALLSENT bit when writing to W_TXCTRL1
escc: always set STATUS_TXEMPTY in R_STATUS on device reset
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
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.

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.

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.

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)

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

Introduce new boolean 'kernel-hashes' option on the sev-guest object.
It will be used to to decide whether to add the hashes of
kernel/initrd/cmdline to SEV guest memory when booting with -kernel.
The default value is 'off'.

hostwin is allocated and added to hostwin_list in vfio_host_win_add, but
it is only deleted from hostwin_list in vfio_host_win_del, which causes
a memory leak. Also, freeing all elements in hostwin_list is missing in
vfio_disconnect_container.

The subsection is not closed by a NULL marker so this can trigger
a segfault when the pmu vmstate is saved.

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.
