KGDB_ARCH_HANDLE_EXC(9)             Kernel Debugger 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.
