Subject: [Qemu-devel] [PATCH 00/10] ppc/pnv: add XIVE support for KVM guests
Date: Sun, 30 Jun 2019 22:45:51 +0200 [thread overview]
Message-ID: <20190630204601.30574-1-clg@kaod.org> (raw)
Hello,
The QEMU PowerNV machine emulates a baremetal OpenPOWER system and
acts as an hypervisor (L0). Supporting emulation of KVM to run guests
(L1) requires a few more extensions, among which support for the XIVE
interrupt controller on POWER9 processor.
The following changes fix some parts of the XIVE model and provide
support for escalations and resend. This mechanism is used by KVM to
kick a vCPU when it is not dispatched on a HW thread.
A series from Suraj adding guest support in the Radix MMU model of the
QEMU PowerNV machine is still required and will be send later. The
whole patchset can be found under :
https://github.com/legoater/qemu/tree/powernv-4.1
Thanks,
C.
