https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D221953 Bug ID: 221953 Summary: cam iosched: Limit the quanta default to hz if it's below 200 Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Keywords: patch Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: fk@fabiankeil.de Flags: mfc-stable11? Created attachment 185945 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D185945&action= =3Dedit cam iosched: Limit the quanta default to hz if it's below 200 The attached patch limits the quanta default to hz if it's below 200 Previously the quanta default was always 200 while hz defaults to 100 when running in a vm. The cam_iosched_ticker() can't be scheduled more than once per tick and some of the limiters depend on quanta matching the number of calls per second to enforce the proper limits.
