Message-ID: <156334225841.840.12435363074113321111.malone@gac.canonical.com> (raw)

UPDATE: Kernel page handling seems to be related to the -smp 2
parameter. Any number > 1 leads to the paging error while omitting the
parameter lead to a running system (without KVM).

Title:
cpu_address_space_init fails with assertion
Status in QEMU:
Confirmed
Bug description:
qemu-system-arm does not start with version >= 2.6 and KVM enabled.
cpu_address_space_init: Assertion `asidx == 0 || !kvm_enabled()'
failed.
Hardware is Odroid XU4 with Exynos with 4.9.61+ Tested with Debian
Stretch (9) or Buster (10).
Without KVM it is running fine but slow. I'm operating Debian Jessie
with qemu 2.1 for a long time with KVM virtualization working
flawlessly. When I upgraded to Stretch I ran into the trouble
described before. I tried Debian Stretch and Buster with all Kernels
provided by the Board manufacturer (Hardkernel).
It seems to be related to the feature introduced in Version 2.6:
https://wiki.qemu.org/ChangeLog/2.6
- Support for a separate EL3 address space
KVM is enabled, so I assume the adress space index asidx to be causing
the assert to fail.
dmesg | grep -i KVM
[ 0.741714] kvm [1]: 8-bit VMID
[ 0.741721] kvm [1]: IDMAP page: 40201000
[ 0.741729] kvm [1]: HYP VA range: c0000000:ffffffff
[ 0.742543] kvm [1]: Hyp mode initialized successfully
[ 0.742600] kvm [1]: vgic-v2@10484000
[ 0.742924] kvm [1]: vgic interrupt IRQ16
[ 0.742943] kvm [1]: virtual timer IRQ60
Full command line is:
qemu-system-arm -M vexpress-a15 -smp 2 -m 512 -cpu host -enable-kvm -kernel vmlinuz -initrd initrd.gz -dtb vexpress-v2p-ca15-tc1.dtb -device virtio-blk-device,drive=inst-blk -drive file=PATHTOFILE,id=inst-blk,if=none,format=raw -append "vga=normal rw console=ttyAMA0" -nographic
Is there anything to do to understand, if this is a hardware related
failure or probably just a missing parameter?
Regards
Lutz
