idle=poll feature straight from xen-unstable none

Description Markus Armbruster 2007-12-07 21:38:13 UTC 
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.

Comment 2 Bill Burns 2007-12-10 13:17:18 UTC 
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.
Comment 4 Don Zickus 2008-01-21 17:30:02 UTC
