As per the IA32 processor manual, the accessed bit is set to 1 in the
processor state after reset. qemu pc cpu_reset code was missing this
accessed bit setting.

That way the interpretation of rmode.active becomes more clear with
unrestricted guest code.

Hi Avi,
I find that the qemu processor reset state is not per the IA32
processor specifications. (Sections 8.1.1 of

In qemu-kvm.git in file target-i386/helper.c in function cpu_reset the

Instead of changing all the checks like this, you can make rmode.active

Unrestricted guest features is introduced in Westmere processor.
Westmere is next to nehalem. And all the following processors will
support it. Westmere would be the 1st processor being built on the 32nm
process.

Attached is the patch for the bugfix1, as we discussed in the earlier

For cpuid leaf 0xb the bits 8-15 in ECX register define the end of
counting leaf.
The previous code was using bits 0-7 for this purpose, which is a bug.

I do find that ioctl in the kvm kernel module code. and the qemu code
