Linux ARM SMP kernel for qemu -- jiffies not updated

thanks for your answers,

[it seems that] the problem was actually related to the version of
Qemu, v0.12.5 never triggered the jiffies update, as described below
for the record, whereas v0.13 is okay !

thanks,

Kevin

jiffies are not updated, and the kernel never goes any further ...
(the second CPU is waiting for an interrup --WFI-- before starting)

do you know if it's feasible to compile a Linux kernel to be run by a
Qemu SMP ARM machine? after so many hours of tries, I can say that any
version of the kernel, any Qemu machine would be okay, provided that
the SMP capability is set, and the kernel boots !

Try the kernel from latest git, QEMU from latest git, and the attached
.config.

The .config is just realview_smp-defconfig with:
?- PB11 and ARMv6 disabled
?- PBX A9 and ARMv7 enabled
?- CONFIG_REALVIEW_HIGH_PHYS_OFFSET disabled

Initramfs support is also enabled. ?You can boot it with this line (you'll
need an initramfs or initrd to get to userspace):

qemu-system-arm -kernel arch/arm/boot/uImage -nographic \
? ? ? ? ? ? ? ?-append "earlyprintk console=ttyAMA0 mem=128M debug" \
? ? ? ? ? ? ? ?-M realview-pbx-a9 -m 128M -initrd ~/kernel/root -smp 2
