| message |
Add a simple spinning mutex for ddb. Unlike mutex(9), this lock keeps on spinning even if `db_active' or `panicstr' has been set. The new mutex also disables IPIs in the critical section. OK mpi@ patrick@ |

| message |
Use the debugger mutex for `ddb_mp_mutex'. This should prevent a race that could leave `ddb_mp_mutex' locked if one CPU incremented `db_active' while another CPU was in the critical section. When the race hit, the debugger was unable to resume execution or switch between CPUs. Race analyzed by patrick@ OK mpi@ patrick@ |
