Members

unsigned char gdb_bpt_instr

The instruction to trigger a breakpoint.

unsigned long flags

Flags for the breakpoint, currently just KGDB_HW_BREAKPOINT.

int (*)(unsigned long, char *) set_breakpoint

Allow an architecture to specify how to set a software breakpoint.

int (*)(unsigned long, char *) remove_breakpoint

Allow an architecture to specify how to remove a software breakpoint.

int (*)(unsigned long, int, enum kgdb_bptype) set_hw_breakpoint

Allow an architecture to specify how to set a hardware breakpoint.

int (*)(unsigned long, int, enum kgdb_bptype) remove_hw_breakpoint

Allow an architecture to specify how to remove a hardware breakpoint.

void (*)(struct pt_regs *regs) disable_hw_break

Allow an architecture to specify how to disable hardware breakpoints for a single cpu.

void (*)(void) remove_all_hw_break

Allow an architecture to specify how to remove all hardware breakpoints.

void (*)(void) correct_hw_break

Allow an architecture to specify how to correct the hardware debug registers.

void (*)(bool on) enable_nmi

Manage NMI-triggered entry to KGDB
