target-xxx: Use fprintf_function (format checking)

fprintf_function uses format checking with GCC_FMT_ATTR.

Format errors were fixed in
  • target-i386/helper.c
  • target-mips/translate.c

Fix cpu_exit for tcp_cpu_exec

If a cpu_exit request is pending, ensure that we leave the CPU loop
quickly. For this purpose, keep the global exit_request pending until
we are about to leave tcg_cpu_exec. Also, immediately break out of the
SMP loop if the request is set, do not run till the end of the chain....

Fix qemu_wait_io_event processing in io-thread mode

When checking for I/O events in the tcg CPU loop, make sure that we
call qemu_wait_io_event_common for all CPUs, not only the current one.
Otherwise pause_all_vcpus may lock up or run_on_cpu requests may starve....

Rename tcg_cpu_exec and tcg_has_work

These functions are also used for kvm under !CONFIG_IOTHREAD, having
'tcg' in their name is just misleading.

Rework debug exception processing for gdb use

Guest debugging is currently broken under CONFIG_IOTHREAD. The reason is
inconsistent or even lacking signaling the debug events from the source
VCPU to the main loop and the gdbstub.

This patch addresses the issue by pushing this signaling into a...

make SIG_IPI to tcg vcpu thread reliable

Store tcg loop exit request on a global variable, and transfer it to

This makes exit request signal from robust. Drop the timedlock hack.
