STRUCT KGDB_ARCH(9) Kernel Debugger Internals STRUCT KGDB_ARCH(9)NAME
struct_kgdb_arch - Describe architecture specific values.
SYNOPSIS
struct kgdb_arch {
unsigned char gdb_bpt_instr[BREAK_INSTR_SIZE];
unsigned long flags;
int (* set_breakpoint) (unsigned long, char *);
int (* remove_breakpoint) (unsigned long, char *);
int (* set_hw_breakpoint) (unsigned long, int, enum kgdb_bptype);
int (* remove_hw_breakpoint) (unsigned long, int, enum kgdb_bptype);
void (* disable_hw_break) (struct pt_regs *regs);
void (* remove_all_hw_break) (void);
void (* correct_hw_break) (void);
void (* enable_nmi) (bool on);
};
MEMBERS
gdb_bpt_instr[BREAK_INSTR_SIZE]
The instruction to trigger a breakpoint.
flags
Flags for the breakpoint, currently just KGDB_HW_BREAKPOINT.
set_breakpoint
Allow an architecture to specify how to set a software breakpoint.
remove_breakpoint
Allow an architecture to specify how to remove a software breakpoint.
set_hw_breakpoint
Allow an architecture to specify how to set a hardware breakpoint.
remove_hw_breakpoint
Allow an architecture to specify how to remove a hardware breakpoint.
disable_hw_break
Allow an architecture to specify how to disable hardware breakpoints for a single cpu.
remove_all_hw_break
Allow an architecture to specify how to remove all hardware breakpoints.
correct_hw_break
Allow an architecture to specify how to correct the hardware debug registers.
enable_nmi
Manage NMI-triggered entry to KGDB

Any one tried puting breakpoint while debugging a core file? I have been using a gdb for running it.. But unsuccessful to put a breakpoint before executing it. Any sugestion or tool for doing it would be welcomed..
Thanks :) (0 Replies)
helo i have asked in exam what that what is the base type of
enum
options are given bewlo
(1) long int
(2) short int
(3) signed int
(4) unsigned int
can u tell me what is the exact answer from the above option

Hi, all:
I am using the KGDB to debug my own network driver on linux. But I suspect if my KGDB work nomally. When I set a breakpoint at "do_one_initcall" function, the kernel function that will call my driver module, and continue to reach there, the "step" command of GDB cannot enter into my... (3 Replies)
