Description Dave Jones 2005-06-23 22:31:39 EDT
We already went through fixing this for FC3, now we have a new variant of this
breakage.

(22:25:48:root@nwo:~)# ll /dev/cpu*
crw-rw----  1 root root 203, 0 Jun 20 04:07 /dev/cpu0
crw-rw----  1 root root 203, 1 Jun 20 04:07 /dev/cpu1
crw-rw----  1 root root 203, 2 Jun 20 04:07 /dev/cpu2
crw-rw----  1 root root 203, 3 Jun 20 04:07 /dev/cpu3

These should be /dev/cpu/N/cpuid
where N is 0 -> 3

Likewise, there should be msr nodes in /dev/cpu/N/

For some reason, I have no /dev/cpu dir at all.

Why does this keep breaking ?
Comment 1 Dave Jones 2005-09-05 01:20:05 EDT
fwiw, rawhide now has this braindamage too. Though a slightly different variant.
It now has symlinks from /dev/cpuN to /dev/cpu/N/cpu
Those symlinks are unnecessary. /dev/cpu/N/cpuid should be the only nodes that
exist.
Comment 2 Dave Jones 2005-11-05 00:22:19 EST
rawhide now seems fixed, fc4 still borken.
Comment 3 Dave Jones 2005-11-13 00:29:37 EST
actually, I take that back.
Rawhide has /dev/cpu/0/cpu  which should be /dev/cpu/0/cpuid

FC4 still has the useless /dev/cpuN symlinks, and similar 'cpu' instead of
'cpuid' breakage.

This breaks x86info, and any other package relying on these nodes being in the
right place.
