It was commited as part of https://bugzilla.yoctoproject.org/show_bug.cgi?id=12301
for kernels < 4.15, as of now oldest builder kernel we have is 4.15 on
ubuntu 18.04 so we should not require this workaround. Moreover, this
fixes an smp problem with qemux86 where no matter what -smp <x> option
is used, qemu always starts with single core.

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

do_testimage[depends] += "swtpm-native:do_populate_sysroot"
* startup commands for swtpm daemon, note that swtpm

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

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

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:

Instead of changing the script environment to affect the child

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

/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

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.

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.

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

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.

RNG passthru has been enabled on all qemu machines but its being added
to each one of them, with this patch its turned into QB variables which
defaults to host passthru, yet it can be overridden if needed via
machine or config metadata if needed.

We have an issue where qemu is being starved of resources on our autobuilders.
We can't raise its priority without special capacilties, therefore add a hook
which if present can allow this to happen using an executable
"~/runqemu-renice".
