aliguori 8c6c919e28 kvm-x86: Remove eflags conversion into emulator format (Jan Kiszka) 
It seems that the conversion of the kernel-delivered eflags state into
qemu's internal split representation was once needed in an older kvm
design (register read-back may have taken place from inside cpu_exec).
Today it is plain wrong and causes incorrect cpu state reporting (gdb,
monitor) and should also corrupt its saving (savevm, migration). Drop
the related lines.

aliguori f55761a0c4 x86: Issue reset on triple faults (Jan Kiszka) 
As discussed a few times on this list: A triple fault causes a system
reset on x86, and some guests make use of this (e.g. 386BSD). To keep
the chance of tracing unexpected resets, log them if CPU_LOG_RESET is
set.

aliguori eca1bdf415 Log reset events (Jan Kiszka) 
Original idea&code by Kevin Wolf, split-up in two patches and added more
archs.

This patch introduces a flag to log CPU resets. Useful for tracing
unexpected resets (such as those triggered by x86 triple faults).

aliguori 165d9b82eb MTRR support on x86 (Carl-Daniel Hailfinger) 
The current codebase ignores MTRR (Memory Type Range Register)
configuration writes and reads because Qemu does not implement caching.
All BIOS/firmware in know of for x86 do implement a mode called
Cache-as-RAM (CAR) which locks down the CPU cache lines and uses the CPU
cache like RAM before RAM is enabled. Qemu assumes RAM is accessible
from the start, but it would be nice to be able to run real
BIOS/firmware in Qemu. For that, we need CAR support and for CAR support
we have to support MTRRs.

This patch is a first step in that direction. MTRRs are MSRs supported
by all recent x86 CPUs, even old i586. Besides influencing cache, the
MTRRs can be written and read back, so discarding MTRR writes violates
the expectations of existing code out there.

An added benefit of this patch is that it fixes the following Linux
kernel error message present in recent kernels (provided the BIOS has
the recent MTRR patches applied):
 ------------[ cut here ]------------
WARNING: at arch/x86/kernel/cpu/mtrr/main.c:1500 mtrr_trim_uncached_memory+0x382/0x384()

This patch prepares the QEMU cpu_watchpoint/breakpoint API to allow the

First of all, it overcomes MAX_BREAKPOINTS/MAX_WATCHPOINTS by switching

This also allows to return a stable reference to the related objects,
required for later introduced x86 debug register support.

Breakpoints and watchpoints are stored with their full information set
and an additional flag field that makes them easily extensible for use
beyond pure guest debugging.

aliguori 7ba1e61953 Add KVM support to QEMU 
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.

splits out the CPUID logic into a separate helper that both the op

aurel32 e65bdffaf2 i386/SVM: return amount of ASIDs 
With SVM the TLB supports tagging to distinguish TLB entries from
different virtual CPUs. This tag is called an ASID. The amount of ASIDs is
given in EBX of the SVM-CPUID-leaf. Currently we return 0, which might
break hypervisors. Let's better return something >0 here, say 0x10.
Since we're flushing the complete TLB on every VM entry and exit we're not
making use of the ASID information anyways.

aurel32 45fd08effd target-i386: Add Core Duo Definition 
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.

pbrook 558fa8361b My core2duo patch introduced a vague statement of "missing features" in 
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.

aliguori c0a04f0e13 Fix up pxe boot (Glauber Costa) 
As discussed in
http://lists.gnu.org/archive/html/qemu-devel/2008-08/msg00667.html,
current pxe boot is broken for some use cases. The problem
goes away if we reduce the number of allowed bits in the address space
to 32 (which has the side effect of reducing guest max mem size to 4Gb).

After digging for a while, it turns out that it happens because pxelinux
tries to access address 0x10009e9a6, which does not fit a 32-bit address.
A closer look, however, reveals this access is totally valid: It's just
0x9e9a6 with an add carry.

To avoid this, this patch casts the address passed to the POPL macro to
a 32-bit value. This is also done, although just theorectically, for
PUSHL too.

aurel32 0ba5f006bb x86/x86-64 MMU PAE fixes 
This patch fixes MMU emulation in PAE mode for > 4GB physical addresses:
- a20_mask should have the correct size to not clear the high part of
  the addresses.
- PHYS_ADDR_MASK should not clear the high part of the addresses.
- pdpe, pde and pte could be located anywhere in memory on x86-64, but
  only in the first 4GB on x86, define their pointer to as target_ulong.
- pml4e_addr could be located anywhere in memory, define its pointer
  as uint64_t.
- paddr represents a physical address and thus should be of type
  target_phys_addr_t.

  and #ifdef TARGET_xxx in softmmu core functions.
Implement per target mmu modes definitions. As an example, add PowerPC

Optimize PowerPC case, precomputing mmu_idx when MSR register changes
  and using the same definition in code translation code.
