Hello,
I'd like to help a bit with GHC work on OpenBSD and would like to give it a try
to port GHC to ARMv8. GHC is a beast so I assume I'll need machine/emulator
with 4GB RAM at least. I'm curious what you guys are using for running all those
ARMv8 packages builders and for your own porting efforts?
so far I see following options:
- qemu-system-aarch64 running on OpenBSD/amd64. I've verified qemu distributed
with 6.2-current
is well capable of running Ubuntu cloud image 16.04 for ARMv8. The question
is, has anybody
here tested that or get OpenBSD/arm64 running on Qemu? The advantage of this
solution is flexibility
qemu is quite a bit slower than real hardware and more painful.
Using U-Boot with a recently proposed but not committed qemu_arm64
target is limited in that virtio devices can't be booted off. Using an
EDK2 OVMF image works better but only if using a QEMU_EFI.fd older than
the prebuilt binaries linaro now provides otherwise there is no console
output after the kernel loads.
Hi all,
This thread caught my attention as I have been doing some experimenting
with ARM virtualization recently - we (Traverse) have a ARM64 board
(NXP/Freescale LS1043 / 4xA53) [1] that runs Linux and I have built a
small distro[2] to host arm64 VM's.
I've had good success with Linux VM's and some success with FreeBSD (i.e
needed older EDK2, and issues with emulated PCIe devices)
OpenBSD does boot under a virtual environment (using the older EDK2 like
FBSD), but the segfaults noted on both the emulated and ThunderX
environments also occur here.
If anyone would like me to try something to debug it, let me know.
The qemu command line used is roughly:
qemu-system-aarch64 --enable-kvm -m 512 -cpu host -M virt,gic_version=2
-smp 1 -mem-path /tmp/hugetlbfs -bios QEMU_EFI_bsd.fd -drive
if=none,file=openbsd.qcow2,id=hd0 -device virtio-blk-device,drive=hd0
