--- Comment #8 from Andriy Gapon <a...@freebsd.org> --- (In reply to Conrad Meyer from comment #7) I don't know epoch(9) / ck_epoch implementation details, but given the constraints[*] of interrupt handling, I think that it could be an overkill. I mean, it probably has some overhead that's avoidable. And for that latency sensitive code it could matter. [*] The interrupt handler list can be iterated only by a single thread / context at a time. Also, we reduce modifications to a single thread at a time using a mutex. Performance of adding and removing interrupt handlers is not critical. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
