Red Hat Bugzilla – Bug 416141
Last modified: 2008-09-18 09:06:39 EDT
The idle=poll kernel parameter causes the kernel to use a polling loop rather
than hypercall down to block. This is useful to profile the amount of sleep
cycles when using xenoprof. Upstream since 3.1.0.
Created attachment 281661 [details]
idle=poll feature straight from xen-unstable
Partner AMD would like this. It adds a boot option useful for profiling but does
not effect normal operation when the boot option is not used.
You can download this test kernel from http://people.redhat.com/dzickus/el5
The patch has been found to cause bug 437252. We're going to yank it. I
recommend to WONTFIX this bug.
Changing state to reflect the removal of the patch.
Closed as won't fix, based on reporter/assignee's comment #6.
