https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D221029 --- Comment #75 from Mark Millard <markmi@dsl-only.net> --- (In reply to Mark Millard from comment #74) I got a lang/ghc build that completed on the Ryzen: # pkg search ghc ghc-8.0.2_1 Compiler for the functional language Haskell This used as a context: sysctl kern.sched.balance=3D0 sysctl kern.sched.steal_idle=3D0 So I'm starting the test of a build attempt in a context with: sysctl kern.sched.balance=3D1 sysctl kern.sched.steal_idle=3D0 also for: PARALLEL_JOBS=3D1 ALLOW_MAKE_JOBS=3Dno and ALLOW_MAKE_JOBS_PACKAGES not having a match for lang/ghc Not that as the system has only general/basic background activities besides the build that: kern.sched.balance=3D1 vs. kern.sched.balance=3D0 likely makes little difference in my context for this test: no need to migrate to a less busy thread. As stands this new build is well past where the combination: sysctl kern.sched.balance=3D1 sysctl kern.sched.steal_idle=3D1 was getting. I'd not be surprise if it completes unless something forces a HW-thread migration to a less busy hw thread (or should I write "core"?). --=20 You are receiving this mail because: You are the assignee for the bug.=
