https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D229106 --- Comment #9 from Conrad Meyer <cem@freebsd.org> --- (In reply to Andriy Gapon from comment #8) Yes, performance of add/remove doesn't matter. But performance of intr_event_handle() matters very much, and adding a contested spin lock to = it seems like a bad idea. I suppose it only needs to be taken for shared interrupts, not MSI, so maybe the impact is not so bad. --=20 You are receiving this mail because: You are the assignee for the bug.=
