When specified it desigantes that the interrupt handler should not lock the vector with a spinlock when executing the installed interrupt handlers. This is necessary to allow the same interrupt vector to be handled in parallel on different CPUs. And it is required for the CPU halt to work synchronously when there is more than one AP CPU. Though the acquire_spinlock() should cause IPIs to be processed, only this fixed the SMP_MSG_FLAG_SYNC problem for me. Not locking is safe as long as it is guaranteed that no interrupt handler is registered or removed while the interrupt handler is running. We can guarantee this for the SMP interrupt handlers we install in arch_smp_init() as they are never uninstalled. Probably this flag should be made private though. Restored the SMP_MSG_FLAG_SYNC when entering the kernel debugger. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23838 a95241bf-73f2-0310-859d-f6bbb57e9c96 |
