Any image that inherits qemuboot must also add image dependencies on
qemu-system-native and qemu-helper-native, otherwise the image won't
be able to be booted.
Currently this is done by conf/machine/include/qemu.inc, but not every
machine that uses qemuboot includes that file.
Move the EXTRA_IMAGEDEPENDS from qemu.inc into qemuboot.bbclass, so that
the dependencies don't have to be duplicated.

Python 3 interprets string literals as Unicode strings, and therefore
\s is treated as an escaped Unicode character which is not correct.
Declaring the RegEx pattern as a raw string instead of unicode is
required for Python 3.

Currently hard-float is dependency upon the special TUNE_CCARGS_MFPU which
contains custom -mfpu= values. However, newer 32-bit architectures like
cortex-r52 use 'simd' instead. There is no 'simd' entry for -mfpu=
according to the GCC manual, it's more or less automatic based on the
cpu settings.
Add this as an exception to the TUNE_CCARGS_FLOAT setting of hard or softfp.

Current include logic goes into generic arm v8/v9 architecture tunes and
adds corresponding -march option after synthesizing it from various tune
fragments, this is fine for a machine which is using armv8/armv9 based
tunes but cortex tunes are intentionally using -mcpu option based on
selected tune value. So when cortex based default tune is selected for a
machine, it will add both -mcpu and -march to the compiler commandline
which can result in invalid combinations for this pair in gcc's own
logic. This can then result in compiler warnings/errors reporting this
e.g.
aarch64-yoe-linux-gcc -mcpu=cortex-a72.cortex-a53 -march=armv8-a+crc+crypto -mbranch-protection=standard
...
cc1: error: switch '-mcpu=cortex-a72.cortex-a53' conflicts with '-march=armv8-a+crc+crypto' switch and resulted in options '+crc+crypto' being added [-Werror]
This is seen in lot of configure test results in glibc 2.39 and the
warning is promoted to errors by gcc in some of these checks especially
with gcc-14, the logs also show it as warning in other places in
configure checks.
mcpu option will compute relevant march implicitly as it specifies a cpu
implementation and this will be the right value to use, therefore do not
specify -march when -mcpu is already describing the cpu.

Fixes [YOCTO #12388]
QEMUs documentation does recommend to not use n270 and core2duo as
an argument to -cpu anymore. See also the QEMU documentation for this at
[0].
Update therefore the QEMU cpu option for the core2duo tune to Nehalam.
Tested it locally with QEMU and KVM.

As per the Arm ARM section A2.3.2, FEAT_CRC32 is mandatory in Armv8.1
onwards, so there's no need to have an explicit optional tune for it.
SVE (which was a choice here) and SVE2 (which was not) are both optional
with v9.0, but GCC's -march=armv9-a defaults to enabling both SVE and
SVE2 on the grounds that there are no implementations of Armv9 that
don't support SVE2. This means there's no point having an explicit sve
feature as it's enabled out of the box.

The modesetting driver works well in qemu, so install it by default. The
plain framebuffer has been buggy in recent 6.4 kernels, a sign that it's
not getting much testing. The Xorg modesetting driver that can use more
powerful virtualised hardware is much better.
We override the default XSERVER because we want to pull in the GLX
extension to exercise that.

In 5c6064 the qemuarm* machines gained vmalloc=256, because in testing
Bruce was seeing problems when the vmalloc area was too big for the
memory size of the machine (eg 256MB).
The intention was for the area to be very small, but 256 bytes is too
small and the kernel sets a minimal vmalloc area of 16MiB:
[ 0.000000] vmalloc area is too small, limiting to 16MiB
However, a 16MiB area is too small and results in pages of messages when
you try and use the system:
[ 242.822481] vmap allocation for size 4100096 failed: use vmalloc=<size> to increase size
There have been a number of changes since this commit, remove the
explicit vmalloc argument and use the default. I've tested that the
system still boots locally.

One or more of the libraries systemd depends on failed to load due to
unresolved symbols/functions. This was intermittent - with a failure
rate estimated between 5% and 30%.
After checking the code, this issue happens on gcc 12, kirkstone is using
gcc 11 works well, with both using the exact same v5.15.84 kernel commit.
There is a kernel fix from upstream [1], they changed the rsize / wsize
to a multiple of PAGE_SIZE, when we applied this patch, the qemuppc64's
default r/wsize went from 4096 to 524288.But the qemuppc64 doesn't have
its own linux-yocto kernel branch, so apply this change might cause
regression with other platforms which share branch with qemuppc64.
So, we added an extra option for nfs rootfs, and set the qemuppc64 default
r/w size to 524288 to line up with the kernel fix[1].
Yocto did a similar thing in the distant past[2] - prior to boot-arg
adjustments existing - by allowing a Kconfig to set the defaults on
nfsboot, in order to work around hardware limitations.

Effectively revert "qemux86-64: build for x86-64-v3 (2013 Haswell and later) rather than Core 2 from 2006"
(commit 6f2af1e5d1537b4d31e14946292bf58f0fd76fc9)
Much as I'd love us to use the latest tuning, we do have some autobuilder
hardware which isn't ready for this yet which breaks KVM and some qemu
user mode usage as there appear to be TCG bugs too. I suspect we're not
the only ones with such hardware.
Drop the tune back to core2-64, anyone can easily customise it
themselves if they need it. We can revisit this in a year or two
as we should be ready then. It has beena good test of the rest of the
support which all seems ready.
I'd have preferred to use corei7-64 but that causes
runqemu.RunqemuTests.test_boot_machine_iso to hang.
Leave the newer tune file inclusion so people can change tunes
more easily.

from 2006
This allows us to
- test those more recent instruction sets (AVX, AVX2, BMI1, BMI2, F16C, FMA, LZCNT, MOVBE, XSAVE)
- benefit from improved performance across the stack both in kvm-driven system emulation and when running
on real silicon.
For example, glibc:
https://www.phoronix.com/news/Glibc-strcasecmp-AVX2-EVEX
v4 level is adding AVX-512, which is far less established, particularly Intel has famously backtracked
from supporting it in Alder Lake/Raport Lake client CPUs and AMD has only implemented it in very recent Zen4 products:

LZCNT, MOVBE, XSAVE)
Qemu 7.2 finally allows us to move beyond building for original Core 2/Core i7 era hardware,
and this patch adds support for the newer generations. But first, a bit of
background:
Recently toolchains gained support for specifying x86-64 'levels' of
instruction set support; v3 corresponds to 2013-era Haswell CPUs
(and later), with AVX, AVX2 and a few other instructions that
were introduced in that generation. I believe this is preferrable
to picking a specific CPU model as the baseline.
Here's Phoronix's feature article that explains the feature and the available levels:
"Both LLVM Clang 12 and GCC 11 are ready to go in offering the new x86-64-v2, x86-64-v3, and x86-64-v4 targets.
These x86_64 micro-architecture feature levels have been about coming up with a few "classes" of Intel/AMD CPU processor support rather than continuing to rely on just the x86_64 baseline or targeting a
specific CPU family for optimizations. These new levels make it easier to raise the base requirements around Linux x86-64 whether it be for a Linux distribution or a particular software application where
the developer/ISV may be wanting to compile with greater instruction set extensions enabled in catering to more recent Intel/AMD CPUs."
https://www.phoronix.com/news/GCC-11-x86-64-Feature-Levels
Here's gcc docs for it:
https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html
And here's the formal specification (click on the pdf link):
https://gitlab.com/x86-psABIs/x86-64-ABI
The actual tune file was created by copying corei7 tunes and doing
search/replace on them. Qemu options were dropped as unnecessary.
32 bit tune was dropped as well, as there is no 32 bit only CPU
that also supports these new instructions; all of the v3 capable
chips are 64 bit.

Back in 0be64e54a0e6 ("qemux86: Allow higher tunes") we moved the
qemux86 machine to using the core-i7 tune file, for maximum flexibility
and to allow for enabling advanced processor features if desired or
required by various packagess, without changing the default tune. Do the
same now for qemux86-64.

OE-core previously carried patches to glibc that added optimized sqrt
implementations for various PowerPC chips. These were recently removed,
which now results in errors when compiling glibc with certian PowerPC
machine tunes:
checking sysdep dirs... configure: error: The 603e subspecies of powerpc is not supported.
Remove setting GLIBC_EXTRA_OECONF with parameters that are no longer
valid. Also remove a commented out setting of the variable that probably
isn't vaild anyway.

Add tune include for armv8.4a. This adds support only for bare armv8.4a
(and for crypto extension). There is no support for additional

These devices are historical, modern Linux will just use the USB
devices, and occasionally the init of these devices fails:
atkbd serio0: Failed to deactivate keyboard on isa0060/serio0
psmouse serio1: Failed to reset mouse on isa0060/serio1: -5
Explicitly add a USB keyboard to go with the USB tablet, and disable the
i8042 entirely.
