7def843a55 runqemu: Fix TypeError when command fails
The commands passed to subprocess are tuples which when passed to a %
format are treated as multiple format arguments instead of a single
argument to be coerced by "%s". This results in a TypeError being
raised with python claiming that not all arguments were consumed.

Fix this by wrapping the command tuple in a str() call, as is done for
the logging strings

44375eccf1 runqemu: direct mesa to use its own drivers, rather than ones provided by host distro
With mesa 23.0, it is not longer possible to use the host drivers, as
mesa upstream has added strict checks for matching builds between
drivers and libraries that load them.

Add a check and a hint to runqemu so that there is a helpful error when
there is no native/nativesdk opengl/virgl support.

0d1023673b runqemu: add QB_SETUP_CMD and QB_CLEANUP_CMD
These enable running custom shell setup and cleanup commands
before and after qemu. Enables machine configurations to for
example run qemu with swtpm to emulate TPM devices.

Example config with meta-tpm2 based swtpm in machine config:

 * image recipe depens on swtpm-native to get the native tools to PATH,
   same handling as qemu itself

do_testimage[depends] += "swtpm-native:do_populate_sysroot"

 * startup commands for swtpm daemon, note that swtpm
   socket file has 107 character limit and absolute paths to build environment
   will not work

QB_SETUP_CMD = " \
   test -d '${IMAGE_BASENAME}_swtpm' || ( mkdir -p '${IMAGE_BASENAME}_swtpm' && \
       swtpm_setup --tpmstate '${IMAGE_BASENAME}_swtpm' --tpm2 --pcr-banks sha256 ); \
   swtpm socket --tpmstate dir='${IMAGE_BASENAME}_swtpm' \
         --ctrl type=unixio,path='${IMAGE_BASENAME}_swtpm/swtpm-sock' \
         --log level=40 --tpm2 -t -d \
"

 * qemu startup command in machine config is configured enable swtpm device

QB_OPT_APPEND += "-chardev socket,id=chrtpm,path='${IMAGE_BASENAME}_swtpm/swtpm-sock' -tpmdev emulator,id=tpm0,chardev=chrtpm -device tpm-tis-device,tpmdev=tpm0"

 * in this case, swtpm daemon stops automatically with qemu machine, but
   QB_CLEANUP_CMD could be used to kill a specific process and wipe
   temporary files

Now runqemu and testimage.bbclass can be used with swtpm.

aa3cb188b8 runqemu: limit slirp host port forwarding to localhost 127.0.0.1
With default slirp port forwarding config qemu listens on TCP ports
2222 and 2323 on all IP addresses available on the build host. Most
use cases with runqemu only need it for localhost and it is not
safe to run qemu images with root login without password enabled
and listening on all available, possibly Internet reachable network
interfaces. Limit qemu port forwarding to localhost 127.0.0.1 IP
address. Now qemu machine SSH and telnet ports are only
reachable from the build host machine, not full Internet.

If qemu machine needs to be reachable from network, then it can
be enabled via local.conf or machine config variable QB_SLIRP_OPT:

QB_SLIRP_OPT = "-netdev user,id=net0,hostfwd=tcp::2222-:22"

8b2348a75e runqemu: Do not perturb script environment
Instead of changing the script environment to affect the child
processes, make a copy of the environment with modifications and pass
that to subprocess.

Specifically, when dri rendering is enabled, LD_PRELOAD was being passed
to all processes created by the script which resulted in other commands
(e.g. stty) exiting with a failure like:

 /bin/sh: symbol lookup error: sysroots-uninative/x86_64-linux/lib/librt.so.1: undefined symbol: __libc_unwind_link_get, version GLIBC_PRIVATE

Making a copy of the environment fixes this because the LD_PRELOAD is
now only passed to qemu itself.

0be2abfe7c runqemu: Allow auto detection of the correct graphics options
Running "runqemu qemux86 kvm" when qemu is configured for sdl and/or gtk
display output currently leads to a poor user experience with no cursor
and corrupted fonts in the gtk case. This is due to no options being
passed to qemu which leads to the loss of the font envirornment variable
and the show-cursor option.

If the user hasn't specified a display type, grep the output of
"qemu-system-xxx --help" for the display types and pick the "best"
which ensures our config is passed in. That resolves the gtk font issue
and the cursor issue with both sdl and gtk.

46a8566183 qemu: add a hint on how to enable CPU render nodes when a suitable GPU is absent
This is particularly useful for llvm-accelerated GL rendering from qemu guest to
an offscreen buffer (accessible over vnc or spice) using llvmpipe on the
host, rather than using unaccelerated swrast renderer in the guest.

This is the best that can be done in the absence of a host GPU with render node
support (such as old Matrox cards common in servers, or fully virtualized cloud
environments with no GPU at all).

Note: even though NVidia blob drivers do support render nodes, they do not
support gbm (yet?), and so rendering will fall back to llvmpipe as well even when
the system has a 3000 euro NVidia GPU. Cue Linus picture.

This will allow the use of a bios (e.g. U-Boot) in combination with
a WIC file (from which U-Boot loads the kernel).

a16d7d2ec6 runqemu: Remove potential lock races around tap device handling
The qemu tap device handling is potentially race ridden. We pass the
fd to the main qemu subprocess which is good as it means the lock is held
as long as the qemu process exists. This means we shouldn't unlock it
ourselves though, only close the file. We also can't delete the file
as we have no idea if qemu is still using it. We could try and obtain
an exclusive new lock, then the file would be safe to unlink but it
doesn't seem worth it.

Also fix the same issue in the port lock code.

d5eb86b3aa runqemu: Ensure we cleanup snapshot files after image run
We need to cleanup snapshot files if we make a copy of them to ensure
the tmpfs doesn't run out of space. There is already NFS code needing
this so make it a generic code path.

232cb7b055 oeqa/runqemu: Support RUNQEMU_TMPFS_DIR as a location to copy snapshot images to
We have a working theory that IO queues on the autobuilder are impacting
runtime testing under qemu, particularly async writes which inice does not
influence. We already pass the snapshot option to qemu which copies the
image and runs out of the copy. Add in the ability to copy the image to
a specificed location which can be a tmpfs. This means that writes to the
image would no longer be blocked by other writes to disk in the system.

Preliminary tests show that this does improve the qemu errors at the expense
of sometimes showing qemu startup timeouts as on a loaded system with a large
test image, it can take longer than 120s to copy the image to tmpfs. Having
a most consistent failure mode for loaded tests is probably desireable though.

16d1669ff9 runqemu: correct forcing of ttyS0
Some platforms do not use ttyS* for their serial consoles (e.g., qemuarm
and qemuarm64).  The hardcoding of this can cause issues.  Modify
runqemu to use the serial consoles defined in SERIAL_CONSOLES instead of
hardcoding.

acfa0e0dce runqemu: Add new option to disable vga emulation
When using nographic, explicitly disabling vga is needed some cases
since some qemu firmware (OpenFirmware ) defaults to std vga, and
when vga is enabled then it disables output to serial and redirects
that to vga which is by design, hwoever we expect the console output
to go to serial when using nographic, therefore its important to
disable vga with nographic especially on qemu based ppc platforms
