Hello,
I'm testing KVM on a Core2 CPU. I'm running kernel 2.6.20-git (pulled
few hours ago), configured with SMP and PREEMPT.
I'm hitting 2 different warnings:
BUG: using smp_processor_id() in preemptible [00000001] code: kvm/7726
caller is vmx_create_vcpu+0x9/0x2f [kvm_intel]
[...]
vmx_create_vcpu calls alloc_vmcs which uses smp_processor_id() in
preemptible context and pass the result to alloc_vmcs_cpu(); at a later
point the function may be running on a different CPU (hence the result
of cpu_to_node may be meaningless).
Second one:
BUG: sleeping function called from invalid context at
/home/kronos/src/linux-2.6.git/mm/slab.c:3034
in_atomic():1, irqs_disabled():0
1 lock held by kvm/12706:
#0: (&vcpu->mutex){--..}, at: [<f1b68d02>] kvm_dev_ioctl+0x113/0xf97
[kvm]
[<b015c32a>] kmem_cache_alloc+0x1b/0x6f
[...]
There are patches for both (I think) flying around. They should land in
Linus' tree in a few days.
Thanks,
