Jan Kiszka 14dcc3e2ac kvm: Fix eflags corruption in kvm mode
This should explain a lot of the weird breakages of upstream KVM we've
seen recently (actually we should have seen it much earlier):

Stop translating eflags into TCG format when in kvm mode as we never
translate it back and rather sync this broken state into the kernel.

Since b567b38 (target-arm: remove T0 and T1, 2009-10-16) the only global
register that is used is AREG0, so the complexity of hostregs_helper.h
is unused.  Use regular assignments and a compiler optimization barrier.

Because Qemu currently requires a TCG target to exist and there are quite some

This is required to make tcg happy. The emulation target itself won't work

Blue Swirl 72cf2d4f0e Fix sys-queue.h conflict for good
Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc923584,
f40d753718,
96555a96d7 and

Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.

Nathan Froyd 0b5c1ce846 cleanup cpu-exec.c, part 0/N: consolidate handle_cpu_signal
handle_cpu_signal is very nearly copy-paste code for each target, with a
few minor variations.  This patch sets up appropriate defaults for a
generic handle_cpu_signal and provides overrides for particular targets
that did things differently.  Fixing things like the persistent (XXX:
use sigsetjmp) should now become somewhat easier.

Previous comments on this patch suggest that the "activate soft MMU for
this block" comments refer to defunct functionality.  I have removed
such blocks for the appropriate targets in this patch.

Anthony Liguori 4a1418e07b Unbreak large mem support by removing kqemu
kqemu introduces a number of restrictions on the i386 target.  The worst is that
it prevents large memory from working in the default build.

Furthermore, kqemu is fundamentally flawed in a number of ways.  It relies on
the TSC as a time source which will not be reliable on a multiple processor
system in userspace.  Since most modern processors are multicore, this severely
limits the utility of kqemu.

kvm is a viable alternative for people looking to accelerate qemu and has the
benefit of being supported by the upstream Linux kernel.  If someone can
implement work arounds to remove the restrictions introduced by kqemu, I'm
happy to avoid and/or revert this patch.

N.B. kqemu will still function in the 0.11 series but this patch removes it from
the 0.12 series.

Paul, please Ack or Nack this patch.

Gleb Natapov b09ea7d55c Handle init/sipi in a main cpu exec loop. (v2)
This should fix compilation problem in case of CONFIG_USER_ONLY.

Currently INIT/SIPI is handled in the context of CPU that sends IPI.
This patch changes this to handle them like all other events in a main
cpu exec loop. When KVM will gain thread per vcpu capability it will
be much more clear to handle those event by cpu thread itself and not
modify one cpu's state from the context of the other.

aurel32 be214e6c05 Fix race condition on access to env->interrupt_request
env->interrupt_request is accessed as the bit level from both main code
and signal handler, making a race condition possible even on CISC CPU.
This causes freeze of QEMU under high load when running the dyntick
clock.

The patch below move the bit corresponding to CPU_INTERRUPT_EXIT in a
separate variable, declared as volatile sig_atomic_t, so it should be
work even on RISC CPU.

We may want to move the cpu_interrupt(env, CPU_INTERRUPT_EXIT) case in
its own function and get rid of CPU_INTERRUPT_EXIT. That can be done
later, I wanted to keep the patch short for easier review.

pbrook 9a3ea65402 When -icount is used and a TB is recompiled due to an IO access
shortly after an IRQ has been raised, env->exception_index will still be set 
to EXCP_IRQ when cpu_io_recompile calls cpu_resume_from_signal.
This causes qemu to repeat the IRQ trap, with disasterous consequences.

I suspect this "works" most of the time because linux tends to drop back to
svc mode before doing actual IRQ processing, and be fairly
tolerant of spurious IRQ traps.

aurel32 d40c54d641 target-i386: SVM: acknowledge interrupt only after it is taken
SVM specifies that the V_IRQ mask is only to be removed, if the
interrupt that is to be delivered actually is delivered.

As of the SVM rewrite, this mask is always unmasked when the main cpu
loop is processed, leaving a corner case where calling the interrupt
handler causes a #PF. In that case (booting Linux / starting gfxboot)
the current implementation tells the VMM the interrupt is taken, even
though it is not.

This patch modifies the VIRQ unmasking to occur after do_interrupt,
making gfxboot work again.

aliguori becfc39041 KVM: simplify kvm_cpu_exec hook
We don't need to use cpu_loop_exit() because we never use the 
condition codes so everything can be folded into a single case.

malc e1638bd858 Fix interrupt exclusion via SSTEP_NOIRQ
Commit #5620 revealed an issue of the SSTEP_NOIRQ masking that was
applied on all interrupt sources (including internal ones) when single
stepping through the guest. Due to that commit, we now ended up in an
infinite loop when CPU_INTERRUPT_EXIT was pending on SSTEP resume. That
was due to #5620 eating all TBs while CPU_INTERRUPT_EXIT is pending, but
SSTEP_NOIRQ preventing CPU_INTERRUPT_EXIT to be processed.

What SSTEP_NOIRQ should actually do is to block the delivery of all
external, guest visible interrupts. With the fix below applied, single
stepping now works again.

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.

malc 55e8b85e48 Add safety net against potential infinite loop
cpu_interrupt might be called while translating the TB, but before it
is linked into a potentially infinite loop and becomes env->current_tb.

Currently this can (and does) cause huge problems only when using
dyntick clock, with other (periodic) clocks host_alarm_handler will
eventually be executed resulting in a call to cpu_interrupt which will
reset the recursion of running TB and the damage is "only" latency.

j_mayer 4710357290 New model for PowerPC CPU hardware interrupt events:
move all PowerPC specific code into target-ppc/helper.c to avoid polluting
the common code in cpu-exec.c. This makes implementation of new features
(ie embedded PowerPC timers, critical interrupts, ...) easier.
This also avoid hardcoding the IRQ callback in the OpenPIC controller,
making it more easily reusable and allowing cascading.
