Hi All,
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 irq264 in interface em0, I did this:
# cpuset -l 3 -x 264
Even doing this, the em0 continues migrating to other CPUafter a short
period of time.
You see it happenwith top -PSH.
Tested on more than one system with FreeBSD 10-STABLE.
FreeBSD xxxx.xxxxx.xxx.xx 10.0-STABLE FreeBSD 10.0-STABLE #9 r267034:

Cheers,
