Signals are slow and do not exist on Win32. The previous patches have done most of the legwork to introduce memory barriers (some of them were even there already for the sake of Windows!) and we can now set the flags directly in the iothread. qemu_cpu_kick_thread is not used anymore on TCG, since the TCG thread is never outside usermode while the CPU is running (not halted). Instead run the content of the signal handler (now in qemu_cpu_kick_no_halt) directly. qemu_cpu_kick_no_halt is also used in qemu_mutex_lock_iothread to avoid the overhead of qemu_cond_broadcast.

This is already useful on Windows in order to remove tls.h, because accesses to current_cpu are done from a different thread on that platform.

This is unused. cpu_exit now is almost exclusively an internal function to the CPU execution loop. In a few patches, we'll change the remaining occurrences to qemu_cpu_kick, making it truly internal.

由 Paolo Bonzini 提交于
The i8257 DMA controller uses an idle bottom half, which by default does not cause the main loop to exit. Therefore, the DMA_schedule function is there to ensure that the CPU relinquishes the iothread mutex to the iothread. However, this is not enough since the iothread will call aio_compute_timeout() and go to sleep again. In the iothread world, forcing execution of the idle bottom half is much simpler, and only requires a call to qemu_notify_event(). Do it, removing the need for the "cpu_request_exit" pseudo-irq. The next patch will remove it. Reviewed-by: NRichard Henderson <rth@twiddle.net> Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

All tcg host architectures now support the guest base and as there is no real performance lost, it can be always enabled. Anyway, guest base use can be disabled lively by setting guest base to 0. CONFIG_USE_GUEST_BASE is defined as (USE_GUEST_BASE && USER_ONLY), it should have to be replaced by CONFIG_USER_ONLY in non CONFIG_USER_ONLY parts, but as some other parts are using !CONFIG_SOFTMMU I have chosen to use !CONFIG_SOFTMMU instead.

Move the muldiv64() function from qemu-common.h to host-utils.h. This puts it together with all the other arithmetic functions where we provide a version with __int128_t and a fallback without, and allows headers which need muldiv64() to avoid including qemu-common.h. We don't include host-utils from qemu-common.h, to avoid dragging more things into qemu-common.h than it already has; in practice everywhere that needs muldiv64() can get it via qemu/timer.h.

After commit 626cf8f4 (icount: set can_do_io outside TB execution, 2014-12-08), can_do_io is set to 1 if not executing code. It is no longer necessary to make this assumption in cpu_can_do_io. It is also possible to remove the use_icount test, simply by never setting cpu->can_do_io to 0 unless use_icount is true. With these changes cpu_can_do_io boils down to a read of cpu->can_do_io.
