Summary: [perfmon] perfmon(4) doesn't work on SMP systems
Product: Base System Reporter: larse <larse>
Component: i386Assignee: Remko Lodder <remko>
Status: Closed FIXED    
Severity: Affects Only Me    
Priority: Normal    
Version: 4.2-RELEASE   
Hardware: Any   
OS: Any   

Description larse 2001-02-09 02:00:01 UTC 
The perfmon(4) driver doesn't work on a kernel that has SMP enabled.
This should be documented in the man page (or better yet, fixed if
possible.)

How-To-Repeat: add this to GENERIC:

	options PERFMON
	options SMP
	options APIC_IO

make depend all install && reboot

run the perfmon example in /usr/share/examples/perfmon, it fails:

[root@hbo: /usr/share/examples/perfmon] ./perfmon 0
perfmon: open: /dev/perfmon: Device not configured

Hello, 

We are much further in time now, and we have a different 
SMP mechanism in place, can you tell me whether your problem 
still persists?

We cannot verify this anymore since the submitters email 
address does no longer exist. 

If anyone has feedback, step up and let me know, I will close 
the PR for now.
