Move all of the tune files found in conf/machine/include into their
respective architecture directories in that same location. All
references to these will need to be updated. So, change the relevant
ones for this tree in this commit as well.
For the ARM tunes, nest them one further into armv8a, armv8m, etc. and
rename some to make them uniform with the rest of the tunes.

Add a new runqemu field for VGA devices. Currently, these are being set
in QB_OPT_APPEND, which can make them difficult to override if importing
the config file into another one.

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.

Major update after v4.2.
Changes:
- os_find_datadir() was changed after the v4.2 release
causing v5.0 to not find the bios and not boot the
image. Fix is sent to upstream qemu.
See: qemu/find_datadir.patch
- v5.0 binary had host contamination for dynamically linked
libraries, "--extra-ldflags='${LDFLAGS}'" in EXTRA_OECONF
resolved the issue
- bluetooth code was removed: qemu.git$ git show 1d4ffe8dc7
hence removed PACKAGECONFIG[bluez]
- -show-cursor qemu option is now deprecated, updated
scripts/runqemu to use updated option instead
- added PACKAGECONFIG definitions
- added qemu-ptest to conf/distro/include/ptest-packagelists.inc
- increased support for ARM architecture, cpu and board
- removed patches merged upstream and refreshed
existing ones
Testing:
Build core-image-minimal against the machines in
openembedded-core/meta/conf/machine and succesfully
booted with qemu v5.0
Ran qemu-ptest on x86-64 and arm64 with identical results:
PASS: 1166
SKIP: 0
FAIL: 0

This is what the upstream recommends nowadays:
https://www.kraxel.org/blog/2014/10/qemu-using-cirrus-considered-harmful/
I have verified that both X and weston continue to boot and look
right; however xorg.conf file needs to be removed as it is cirrus
specific and doesn't work and isn't needed with std vga.

This helps in booting weston images ( core-image-weston ) with fbdev
backend, without this westons initialization of fbdev backend fails
because it does not get correct frame buffer settings and exits
pre-maturely

This is the qemu default since qemu 2.2, is generally supported better,
and is recommended by upstream. It also has already been in use for arm/risc
and ovmf.

'-vga virtio' emulated hardware remains in use when virgl is enabled via a runqemu override.
Also, adjust the error whitelist, as there is a number of new messages
coming from the drivers that are not actual errors.

There was a discussion about what amount of RAM is appropriate for a
default; the outcome was that for now it is still 256M. Some qemu machine
definitions have however set this to 512M so for the sake of
treating all architectures fairly, they are reset back to 256M.
Also runqemu is adjusted to use 256M if QB_MEM is not set at all.

Just adding `-device virtio-rng-pci' to the QEMU invocation will
add the device with a default host backend. As of QEMU 1.3+,
the default backend is to use the host's /dev/random as a
source of entropy. [1]
When the entropy pool is empty, reads from /dev/random will
block until additional environmental noise is gathered. [2]
For Yocto, if call runqemu frequently, it will consume lots
of host's /dev/random, and kernel finish crng init in guest get
more and more slowly.
Here are 4 times runqemu boot test:
[ 3.464432] random: crng init done
[ 20.874030] random: crng init done
[ 23.583589] random: crng init done
[ 23.858945] random: crng init done
Modify entropy source to /dev/urandom device on the host which
returns random bytes using a pseudorandom number generator seeded
from the entropy pool. Reads from this device do not block and
kernel finish crng init in guest will not delay.
Of course, the side effect is obviously, we lost the quality of
randomness, but the modification is only on runqemu script
rather than real embedded device, and it benefits oeqa efficiency
in which many cases call runqemu especially multiple oeqa builds
on one host.
After apply the fix:
[ 3.364670] random: crng init done
[ 4.619061] random: crng init done
[ 3.403897] random: crng init done
[ 3.450717] random: crng init done

Replace the deprecated '-usbdevice' option with '-device usb-xx' option.
This would fix runqemu boot error like below.
'-usbdevice' is deprecated, please use '-device usb-...' instead

Bring across the comment that was in runqemu regarding why the
virtio-rng-pci device was needed. This comment is added to each location
where the virtio-rng-pci device is added.

Not all QEMU machines (outside of those available in OE-Core) are
capable of using the virtio-rng-pci device due to various machine models
not having a pci/virtio bus. This makes it such that the use of the
'-device virtio-rng-pci' flag to QEMU is machine specific.
This patch removes the general addition of the flag to all runqemu
targets and adds the flag into the QB_OPT_APPEND for all the qemu*
machines in OE-Core that support its use (which is all of them).
