Hi,
  I am trying to install kvm on ppc64 system (imac G5). I have built
kernel with kvm module. When I try to install qemu, I am getting this
error

$ ./configure --enable-kvm --target-list="ppc-softmmu"

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?

< 2.6.33. Lacking build-time KVM_CAP check? Or is such a kernel too old
anyway? Then catch it during configure and point the user to... well...
there is no kvm-kmod with kernel header updates for PowerPC. Hmm... ;)

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.

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,

The kernel log ring buffer is probably faster filled than read :).

Better don't make them printks - just use the tracing framework. I'd write up a small howto here myself, but I'm pretty much on the jump to my plane for vacation. Avi, could you please guide him a bit on how to get data out of tracepoints?

This means exactly what it means. There are two possible causes:

1) Your kernel is too old and doesn't support the capability
2) Qemu was compiled with kernel headers that don't know the capability yet

If it's 2, just copy some of the kvm*.h files from your kernel source over to /usr/include/linux or /usr/include/asm-powerpc and fix them up to compile (remove __user).

Thanks for the quick reply :)
I have added some more trace parameters in the tracing framework and 
currently, it is working fine.
1. Add new field in "struct kvm_vcpu_stat" (kvm_host.h)
2. Add corresponding entry in "struct kvm_stats_debugfs_item 
debugfs_entries[]" (book3s.c)
3. Increment or Decrement that field where ever necessary.

I can see stats for the new parameter in kvm_stat output. I guess, this 
approach is okay.

Those aren't tracepoints; they're deprecated debug statistics.

For tracepoints, see

   include/trace/events/kvm.h (general kvm tracepoints)
   arch/powerpc/kvm/trace.h (ppc specific tracepoints)
   arch/powerpc/kvm/book3s_mmu_hpte.c (examples of use, look for
