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¶
int vector
The error vector of the exception that happened.
int signo
The signal number of the exception that happened.
int err_code
The error code of the exception that happened.
char * remcom_in_buffer
The buffer of the packet we have read.
char * remcom_out_buffer
The buffer of BUFMAX bytes to write a packet
into.
struct pt_regs * 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.
