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.
