https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D229764 --- Comment #1 from Andriy Gapon <avg@FreeBSD.org> --- First, ARC does not have any parallel or magic mechanism to wire memory. It uses uma(9) and those allocations go through the normal / common memory wir= ing mechanism. Second, vm.max_wired only affects memory wiring from userland (e.g. mlock(2) calls). It cannot deny kernel memory allocations. There is a different mechanism to stall kernel memory allocations (M_WAITOK) when the physical memory gets low. So, I am not sure if this proposal makes much sense. --=20 You are receiving this mail because: You are the assignee for the bug.=
