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
