From 3a93261f70c7b92f84fb211b66f1d4e66c0b3dce Mon Sep 17 00:00:00 2001 From: Ashish Kalra Date: Thu, 19 May 2011 08:54:28 -0500 Subject: powerpc: introduce the ePAPR embedded hypervisor vmpic driver The Freescale ePAPR reference hypervisor provides interrupt controller services via a hypercall interface, instead of emulating the MPIC controller. This is called the VMPIC. The ePAPR "virtual interrupt controller" provides interrupt controller services for external interrupts. External interrupts received by a partition can come from two sources: - Hardware interrupts - hardware interrupts come from external interrupt lines or on-chip I/O devices. - Virtual interrupts - virtual interrupts are generated by the hypervisor as part of some hypervisor service or hypervisor-created virtual device. Both types of interrupts are processed using the same programming model and same set of hypercalls.
