Bug ID: 190785
Summary: cpu affinity not work in FreeBSD 10-STABLE
Product: Base System
Version: 10.0-STABLE
Hardware: Any
OS: Any
Status: Needs Triage
Severity: Affects Many People
Priority: ---
Component: bin
Assignee: freebsd-bugs@FreeBSD.org
Reporter: gon...@bsdinfo.com.br
Hi,
Recently noticed the following:
# devinfo -rv
em0 pnpinfo vendor=0x8086 device=0x105e subvendor=0x8086
subdevice=0x135e class=0x020000 at slot=0 function=0
Interrupt request lines:
264
pcib1 I/O port window:
0x4020-0x403f
pcib1 memory window:
0xc1240000-0xc125ffff
0xc1260000-0xc127ffff
After discovering the irq 264 in interface em0, I did this:
# cpuset -l 3 -x 264
Even doing this, the em0 continues migrating to other CPU after a short
period of time.
You see it happen with: top -PSH.
Tested on more than one system with FreeBSD 10-STABLE.
