      x86 cleanup · d9957a8b
      blueswir1 authored 
      Remove some unnecessary includes, add needed includes, move prototypes to
cpu.h to suppress missing prototype warnings.

Remove unused functions and prototypes (cpu_x86_flush_tlb, cpu_lock,
cpu_unlock, restore_native_fp_state, save_native_fp_state).

Make some functions and data static (f15rk, parity_table, rclw_table,
rclb_table, raise_interrupt, fpu_raise_exception), they are not used
outside op_helper.c anymore.

Make some x86_64 and user only code conditional to avoid warnings.

Document where each function is implemented in cpu.h and exec.h.

      Add KVM support to QEMU · 7ba1e619
      aliguori authored 
      This patch adds very basic KVM support.  KVM is a kernel module for Linux that
allows userspace programs to make use of hardware virtualization support.  It
current supports x86 hardware virtualization using Intel VT-x or AMD-V.  It
also supports IA64 VT-i, PPC 440, and S390.

This patch only implements the bare minimum support to get a guest booting.  It
has very little impact the rest of QEMU and attempts to integrate nicely with
the rest of QEMU.

Even though this implementation is basic, it is significantly faster than TCG.
Booting and shutting down a Linux guest:

w/TCG:  1:32.36 elapsed  84% CPU

w/KVM:  0:31.14 elapsed  59% CPU

Right now, KVM is disabled by default and must be explicitly enabled with
 -enable-kvm.  We can enable it by default later when we have had better
testing.

      Split CPUID from op_helper · 6fd805e1
      aliguori authored 
      KVM needs to call CPUID from outside of the TCG code.  This patch
splits out the CPUID logic into a separate helper that both the op
helper and KVM can call.

      target-i386: Add Core Duo Definition · 45fd08ef
      aurel32 authored 
      This patch adds a CPU definition for the Core Duo CPU. I tried to
resemble the original as closely as possible and document what features
are missing still. This patch enables the use of a recent CPU definition
on 32 bit platforms.

It also fixes two issues that went along the line:

- invalid xlevel in core2duo spec
  While looking though the CPUIDs again, I found that xlevel is actually 8.

- non-PSE36 support
  The CoreDuo CPUID does not expose the PSE36 capability, but CPUID
0x80000008 is tied to 36 bits. This broke Windows XP installation for
me, so I just set it to 32 bits width when PSE36 is not available. The
original CPU also exposes 32 bit width in CPUID 0x80000008.

      My core2duo patch introduced a vague statement of "missing features" in · 558fa836
      pbrook authored 
      the CPUID specification. This patch addresses this by specifying exactly 
what is missing.
While going along the missing CPUID entries I also stumbled across 
invalid and missing CPUID #defines while comparing them to the Intel 
Documentation. This patch also addresses these. I found them too minor 
to split them up in a separate patch.

Furthermore I looked through CPUID functions > 5 and realized that it 
should be safe to bump the level to 10. I tried booting Linux with that 
and it worked fine.
