From: Marco Felsch <m.felsch@pengutronix.de>
This adds the support for the barebox bootloader to oe-core. The recipe
is inspired by meta-ptx [1] but is a major rework of the one found there.
Barebox comes with a wide range of supported architectures and follows
the concepts of Linux in various aspects like the driver model, the
shell, or the virtual file system.
This not only eases porting Linux drivers but also makes barebox a
developer-friendly and feature-rich bootloader alternative [2].
For barebox (like for the kernel or other bootloaders) it is quite
likely that people will not just build the original recipe but need to
adapt it, point to custom repositories, apply patch stacks,
COMPATIBLE_MACHINE etc. They may also choose to have different recipe
names for different variants.
Having only a single .bb file and requiring to copy or .bbappend it is
inconvenient and results in unnecessary code duplication. Therefore, the
base support for building barebox is encapsulated in barebox.bbclass
(like kernel.bbclass for the kernel).
Adds barebox to maintainers.inc but excludes it from the maintainers
check since with the current check mechanism barebox would be skipped
(and making the check fail) due to not being the PREFERRED_PROVIDER for
virtual/bootloader.

Add initial support to build the barebox tools for the host and the
target.
Some of the tools are generic barebox utilities (like 'bareboximd' for
image meta data inspection or 'bareboxenv' for accessing the barebox
environment) some are SoC family-specific specific utilities (like
'imx-usb-loader' or 'omap3-usb-loader').

These are set in the barebox recipe rather in the corresponding machines
(where they would belong otherwise) to keep the impact of barebox to
oe-core minimal for now.
"multi_v7_defconfig" is used for qemuarm since this is the default
barebox armv7 config that just enables all supported platforms.
"multi_v8_defconfig" is used for qemuarm64 sine this is the default
barebox armv8 config that just enables all supported platforms.
"efi_defconfig" is used for qemux86-64 which is the primary platform
where barebox will not be the first stage bootloader but an EFI payload.
Since these changes make barebox a provider for virtual/bootloader,
explicitly default to u-boot in the corresponding MACHINE configs to not
unnecessarily surprise users.

From: Enrico Jorns <ejo@pengutronix.de>
If we talk to terminals that like colors, we need to ignore the vt100
escape sequences when matching strings.
An unprocessed barebox console prompt would e.g. look like:
ESC[1;32mbarebox@ESC[1;36mARM QEMU virt64:/ESC[0m
where we cannot match for something like "barebox@ARM QEMU virt64:/".
The same applies to colored Linux terminal output of course.
The "\x1b\[" from the regex catches the standard start of ANSI escape
sequence while the rest catches the actual command code executed.

This allows defining non-standard patterns from QEMU tests just as they
are already supported by the testimage.bbclass.
Will allow testing non-Linux shells in QEMU, too (e.g. a U-Boot shell or
another bootloader shell).

This looked better in testing, thanks. There was:
https://valkyrie.yoctoproject.org/#/builders/23/builds/168/steps/14/logs/stdio
which is from oe-selftest on an ARM server though :/

Thank you for the test log!
I'll try to figure out why it works in my test setup but doesn't in the autobuilder..
Not sure if I'll have the chance to reproduce it on an ARM host.
Barebox doesn't seem to boot at all (or output is missing) and U-Boot got stuck.
U-Boot log in the failed test says

I tried reproducing the breakage on a Librecomputer Alta (Cortex-A73/A53) with Debian 12
for arm64, but without success. Details below.
I applied this series on top of commit

My successful run looks identical to yours. barebox start up is also
successful and uneventful.
Note that barebox' XHCI driver doesn't have PCI support unlike U-Boot, so
if the same issue is affecting both barebox and U-Boot breakage in CI,
it might not be USB emulation related as barebox doesn't do any
USB on that platform...
Is `selftest -r uboot -v -v -v -K` close enough to what the CI server runs
or should I try something else to reproduce this?
Thanks,
Ahmad

That should have worked. "selftest -r barebox" should also fail.
The config used on the autobuilder for that can be seen here:
https://valkyrie.yoctoproject.org/#/builders/23/builds/168/steps/13/logs/stdio
in case the MACHINE value in particular makes a difference.

I am building for MACHINE = "qemuarm64" already, but something else catches
my eye: QEMU_USE_KVM = 'True'
I wasn't aware that I need to manually set this. I do this now and it fails
for other reasons: qemu-system-aarch64: KVM does not support GICv3 emulation
I'll look into how to resolve this and maybe I am lucky and can reproduce
this issue, once KVM is enabled.
Can you share what SoC is used for the ARM CI server? I assume it doesn't
run into this problem, because it has a GIC >= v3. Mine is a GIC-400,
which apparently only implements GICv2.

Ahmad

Good news: I managed to reproduce this issue and write a few lines long reproducer
that I sent in a bug report to the KVM/QEMU development mailing lists:
https://lore.kernel.org/all/89f184d6-5b61-4c77-9f3b-c0a8f6a75d60@pengutronix.de/
I will look after any fixes that may result.
As far as this series here is concerned, both barebox and U-Boot function correctly
with KVM disabled, so could we just disable KVM for only the U-Boot/barebox runqemu tests
to unblock merge of this series?
Some more info on my debugging below.
I managed to reproduce by enabling KVM and changing:
-QB_CPU_KVM = "-cpu host -machine gic-version=3"
+QB_CPU_KVM = "-cpu host -machine virt"
and by disabling migration across the big-little cluster with
taskset -a --cpu-list 2-5
I even got a U-Boot crash register dump:
Flash: 64 MiB

Removing -enable-kvm makes the issue disappear. barebox also reaches
the shell normally when -enable-kvm is omitted.
Given that I am more familiar with barebox (and the stack traces there
actually walk the stack and contain symbols if the data abort happens
after the vector table is installed), I debugged the issue there and
narrowed it down to a specific encoding of the LDR instruction operating
on an MMIO peripheral.
More information about that in the bug report linked above.

TL;DR: Turns out this is not a bug, but a known quirk of KVM and software that
wishes to run under KVM needs to adapt the instructions it uses to access MMIO
regions accordingly.
For barebox, I sent a series adding KVM compatibility here:
https://lore.kernel.org/barebox/20241009060511.4121157-1-a.fatoum@pengutronix.de
For U-Boot, I reported the issue here:
https://lore.kernel.org/u-boot/2211f9f0-cd7d-4b55-860d-a34c04877e7b@pengutronix.de

I am more certain now that we should disable KVM for bootloader testing.
Full system tests with Linux are much more demanding, so KVM absolutely
makes sense there.
In the bootloader however, normal emulation should suffice, especially when
their upstream isn't KVM-compatible yet anyway.
Cheers,
Ahmad
