Hi, GDB developpers:  In mulit-threading ,when a thread encounter a breadpoint, how  does the gdbserver find out  the thread encounting the breakpoint? Because many threads may encounter the same breakpoint.

In the case of Linux kernel it reports SIGTRAP for the specific task
(=thread).  waitpid returns PID (TID) of that thread.
