Title:
qemu-system-arm hangs on SIGUSR1 on OS X 10.8.2
Status in QEMU:
New
Bug description:
I built the latest version of QEMU
commit b4ae3cfa57b8c1bdbbd7b7d420971e9171203ade
Date: Mon Oct 1 12:34:37 2012 +1000
My system is:
Darwin localhost 12.2.0 Darwin Kernel Version 12.2.0: Sat Aug 25 00:48:52 PDT
2012; root:xnu-2050.18.24~1/RELEASE_X86_64 x86_64
localhost:qemu oliverks$ gcc -v
Using built-in specs.
Target: i686-apple-darwin11
Configured with:
/private/var/tmp/llvmgcc42/llvmgcc42-2336.11~28/src/configure
--disable-checking --enable-werror

--target=i686-apple-darwin11 --with-gxx-include-dir=/usr/include/c++/4.2.1
Thread model: posix
gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)
Shortly after start up I freeze. I am running the command line
./arm-softmmu/qemu-system-arm -M lm3s811evb -kernel
../FreeRTOSV7.2.0/FreeRTOS/Demo/CORTEX_LM3S811_GCC/gcc/RTOSDemo.axf
The hang appears to occur due to this signal being sent
static void qemu_tcg_init_cpu_signals(void)
{
sigset_t set;
struct sigaction sigact;
memset(&sigact, 0, sizeof(sigact));
sigact.sa_handler = cpu_signal;
sigaction(SIG_IPI, &sigact, NULL); // <-- Signal that hangs system
sigemptyset(&set);
sigaddset(&set, SIG_IPI);
pthread_sigmask(SIG_UNBLOCK, &set, NULL);
}
