Had attached the patch as a binary stream by mistake (default for my mail client). Not sure if thats acceptable for the Xen list. Fixed it. -Amitabha On 1/1/07, Amitabha Roy <amitabha.roy@xxxxxxxxx> wrote: Hi The attached patch implements the idle=poll option in the kernel when running on Xen. This causes the kernel to use a polling loop rather than hypercall down to block. I have found this useful to profile the amount of sleep cycles when using xenoprof, there may be other uses.
