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.
