v5: Rebase and improve the test. Please review again.
Patch dependencies:
This test depends on the qtest timer fix to run correctly.
http://lists.gnu.org/archive/html/qemu-devel/2015-01/msg01865.html
Also depends on the os check fix to run at all:
This adds scripts/qtest.py as a python library for qtest protocol.

QMP command block_set_io_throttle expects underscores in parameters
instead of dashes: {iops,bps}_{rd,wr,max}.
Add optional argument conv_keys (defaults to True, backward compatible),
it will be used in IO throttling test case.

This case utilizes qemu-io command aio_{read,write} -q to verify the
effectiveness of IO throttling options.
It's implemented by driving the vm timer from qtest protocol, so the
throttling timers are signaled with determinied time duration. Then we
verify the completed IO requests are within 10%
This will allow test case to run command in qtest protocol. It's
write-only for now.

This allows to put the dirty bitmap into a disabled state where no more
writes will be tracked.
It will be used before backup or writing to persistent file.

spinlock is only used in two cases:
* cpu-exec.c: to protect TranslationBlock
* mem_helper.c: for lock helper in target-i386 (which seems broken).
It's a pthread_mutex_t in user-mode so better using QemuMutex directly in this
case.
It allows as

This adds a lock to avoid multiple exclusive access at the same time in case of
TCG multithread.

This finally allows TCG to benefit from the iothread introduction: Drop
the global mutex while running pure TCG CPU code. Reacquire the lock
when entering MMIO or PIO emulation, or when leaving the TCG loop.
We have to revert a few optimization for the

This removes tcg_halt_cond global variable.
We need one QemuCond per virtual cpu for multithread TCG.

In order to have one TCGContext per thread and a single TBContext we have to

This removes exit_request global and adds a variable in CPUState for this.
Only the flag for the first cpu is used for the moment as we are still with one
TCG thread.

Hi everybody,
This is the start of our work on TCG multithread.
We send it for comment to be sure we are taking the right direction.
We already discussed the first patch but we keep it for simplicity.

This protects TBContext with tb_lock to make tb_* thread safe.
We can still have issue with tb_flush in case of multithread TCG:
An other CPU can be executing code during a flush.
This can be fixed later by making all other TCG thread exiting

Not all targets define a full set of suffix strings for the
NB_MMU_MODES that they have. In this situation, don't define any
helper functions for that mode, rather than defining helper functions
with no suffix at all. The MMU mode is still functional; it is merely
not directly accessible via
