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