Hi...
I have a little problem with microcode_ctl and udev.
Mandrake 10.1 Cooker has switched fully to udev, and microcode_ctl fails
to open the 'microcode' device.
It looks like udev creates /dev/microcode, but microcode_ctl looks for
/dev/cpu/microcode.
Which is the right location ?
Versions:
werewolf:~# rpm -q udev microcode_ctl
udev-030-10mdk
microcode_ctl-1.08-1mdk
TIA

/dev/cpu/microcode according to the LANANA registration table

I solved this with a rule in rules.d:
KERNEL="microcode", NAME="cpu/microcode"
But where is the default ? Kernel or userspace ? And why is it not created
in the right place ?
TIA
