Hrm. This means that your kernel headers in /usr/include/linux are too old. Can
you try and find out which kernel version they are from please
Yes, kernel headers version is 2.6.32. For the time being, I copied some of the
header files from kvm/arch/powerpc/include/asm/ to kernel headers and qemu
build was successful.
Thanks a lot.
Awesome! I'm eager to hear how well it works for you :)
I collected some performance stats using kvm_stat. To get more
information about exit counts of individual instructions, I configured
CFLAGS_emulate.o with DDEBUG flag.
Now, I can see output of "pr_debug("Emulating opcode %d / %d\n",
get_op(inst), get_xop(inst));" instruction in kernel logs.
I have two queries:
1. The count of "Emulating opcode...." statement in /var/log/kern.log (3
million) is coming out to be much less than emulated_inst_exits (22
million) using kvm_stat.
2. How to configure makefiles to get output of printk statements inside
kvm/arch/powerpc/kvm/trace.h
Also, every time I start kvm, I get this error "KVM: Couldn't find level
irq capability. Expect the VM to stall at times". After some time, the
VM just hangs. I traced this output to qemu/target-ppc/kvm.c Is there
any way to avoid it.
Thanks,
