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 īcī and īsī 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.
