sysfs cpu?/topology is empty in 2.6.25
Last modified: 2016-02-09 20:32:48 EST
An error in conditional compilation disabled /sys/devices/cpu/cpu*/topology/ in
the 2.6.25 kernel. This is a regression from Fedora 8.
Please consider carrying the upstream patch at
5c3a121d52b30a1e53cdaa802fa1965fcd243164 until the F9 kernel rebases to
2.6.26-rc2 or later. irqbalance, among other things, depends on the cpu topology
This is in 188.8.131.52, which the current cvs has updated to.
It'll be in an update soon.
wait a second..
/sys/devices/cpu never existed. it's always been /sys/devices/system/cpu
and looking on 2.6.25-14.fc9.x86_64 I see /sys/devices/system/cpu/cpu*/topology/
just fine. What's going on here?
ah, this only affected 32 bit. never mind.
my bad. I should have said "on 32bit". I did set the Hardware to x86
and I typoed the /sys/devices/system/cpu/cpu*/topology/
This is fixed in the current F9 kernel.
