Hi, I'd like to use the perfc API to report counters not easily countable (such as the number of valid entries in a table. Counting it on the fly may be very costly). These hooks provide the basic infrastructure for that. (empty hooks added for ia64 and powerpc, x86 hooks call ptwr_eip_stat_XX). Tristan.
