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
