77 * FUNCTION: Sets a hardware breakpoint
79 * i = breakpoint to set (0 to 3)
80 * addr = linear address to break on
81 * type = Type of access to break on
82 * len = length of the variable to watch
84 * The variable to watch must be aligned to its length (i.e. a dword
85 * breakpoint must be aligned to a dword boundary)
87 * A fatal exception will be generated on the access to the variable.
88 * It is (at the moment) only really useful for catching undefined
89 * pointers if you know the variable effected but not the buggy
92 * FIXME: Extend to call out to kernel debugger on breakpoint
93 * Add support for I/O breakpoints
94 * REFERENCES: See the i386 programmer manual for more details
