This change adds a efi/run script inspired by the one in x86. This
script will setup a folder with the test compiled as an EFI app and a
startup.nsh script. The script launches QEMU providing an image with
EDKII and the path to the folder with the test which is executed
automatically.
For example:
$> ./arm/efi/run ./arm/selftest.efi setup smp=2 mem=256
This should be
./arm/efi/run ./arm/selftest.efi -append "setup smp=2 mem=256" -smp 2 -m 256
Indeed, I will update the commit message.
but I can't get any tests to run through ./arm/efi/run. All of them
immediately die with a DABT_EL1. I can get the tests to run (and pass) by
manually booting into UEFI with the FAT partition pointing at the parent
directory
I suppose the DABT_EL1 is happening after the test has started and not while
the UEFI interactive shell starts?
The countdown completes and the startup script runs (I can add an echo to
check it). So it must be the test that fails.
$QEMU -nodefaults -machine virt -accel tcg -cpu cortex-a57 \
-device pci-testdev -display none -serial stdio \
-bios /usr/share/edk2/aarch64/QEMU_EFI.silent.fd \
-drive file.dir=efi-tests/,file.driver=vvfat,file.rw=on,format=raw,if=virtio
Do you hit the DABT_EL1 if you let it automatically start using the
startup.nsh prepared by the ./arm/efi/run script? Meaning change the above
command if you provided -drive file.dir=efi-tests/timer instead:
$QEMU -nodefaults -machine virt -accel tcg -cpu cortex-a57 \
-device pci-testdev -display none -serial stdio \
-bios /usr/share/edk2/aarch64/QEMU_EFI.silent.fd \
-drive file.dir=efi
tests/timer,file.driver=vvfat,file.rw=on,format=raw,if=virtio
Yes, this is what ./arm/efi/run does, and it doesn't help to use the
command line directly.
Thanks for reviewing this!
Nikos
and then, for example for the timer test, doing
fs0:
cd timer
timer.efi
This actually doesn't work. I was actually doing
fs0:
cd timer
ls
timer.efi
and, believe it or not, without the 'ls' I get the dabt, with the 'ls' the
test runs and passes. Adding an 'ls' to the startup script doesn't help
the automatic execution though.
Which versions of QEMU and edk2 are you using? And what file system do you
have the efi-tests directory on?
I am using the QEMU_EFI.fd image that comes with Ubuntu 20.04.6
(0~20191122.bd85bf54-2ubuntu3.4)
https://packages.ubuntu.com/focal-updates/qemu-efi-aarch64
and I've tried two different versions of QEMU
$> qemu-system-aarch64 --version
QEMU emulator version 4.2.1 (Debian 1:4.2-3ubuntu6.24)
Copyright (c) 2003-2019 Fabrice Bellard and the QEMU Project developers
$> ../qemu/build/qemu-system-aarch64 --version
QEMU emulator version 7.0.0 (v7.0.0-dirty)
Copyright (c) 2003-2022 Fabrice Bellard and the QEMU Project developers
efi-tests is on ext4
I am happy to have a closer look if you help me reproduce your environment.
Thanks,
Nikos
