From cdd6ad3ac63d2fa320baefcf92a02a918375c30f Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Tue, 5 Mar 2019 05:30:01 -0500 Subject: KVM: polling: add architecture backend to disable polling There are cases where halt polling is unwanted. For example when running KVM on an over committed LPAR we rather want to give back the CPU to neighbour LPARs instead of polling. Let us provide a callback that allows architectures to disable polling.
