2012-10-31qemu-thread: add QemuSemaphorePaolo Bonzini1-0/+4
The new thread pool will use semaphores instead of condition variables, because QemuCond does not have qemu_cond_timedwait. (I also like it more this way). Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2011-12-15fix win32 buildPaolo Bonzini1-0/+3
On Windows, cpus.c needs access to the hThread. Add a Windows-specific function to grab it. This requires changing the CPU threads to joinable. There is no substantial change because the threads run in an infinite loop. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-12-12qemu-thread: implement joinable threads for Win32Paolo Bonzini1-2/+3
Rewrite the handshaking between qemu_thread_create and the win32_start_routine, so that the thread can be joined without races. Similar handshaking is done now between qemu_thread_exit and qemu_thread_join. This also simplifies how QemuThreads are initialized.

2011-03-13add win32 qemu-thread implementationPaolo Bonzini1-0/+21
For now, qemu_cond_timedwait and qemu_mutex_timedlock are left as POSIX-only functions. They can be removed later, once the patches that remove their uses are in. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
