KGDB_ARCH_HANDLE_EXC(9) KGDB Internals KGDB_ARCH_HANDLE_EXC(9) NAME
kgdb_arch_handle_exception - Handle architecture specific GDB packets. SYNOPSIS
int kgdb_arch_handle_exception(int vector, int signo, int err_code, char * remcom_in_buffer, char * remcom_out_buffer, struct pt_regs * regs); ARGUMENTS
vector The error vector of the exception that happened. signo The signal number of the exception that happened. err_code The error code of the exception that happened. remcom_in_buffer The buffer of the packet we have read. remcom_out_buffer The buffer of BUFMAX bytes to write a packet into. regs The struct pt_regs of the current process. DESCRIPTION
This function MUST handle the 'c' and 's' command packets, as well packets to set / remove a hardware breakpoint, if used. If there are additional packets which the hardware needs to handle, they are handled here. The code should return -1 if it wants to process more packets, and a 0 or 1 if it wants to exit from the kgdb callback. AUTHORS
