Subject: [RFC PATCH v0 0/5] PPC: KVM: pseries: Asynchronous page fault
Date: Thu, 05 Aug 2021 07:36:34 +0000 [thread overview]
Message-ID: <20210805072439.501481-1-bharata@linux.ibm.com> (raw)
Hi,
This series adds asynchronous page fault support for pseries guests
and enables the support for the same in powerpc KVM. This is an
early RFC with details and multiple TODOs listed in patch descriptions.
This patch needs supporting enablement in QEMU too which will be
posted separately.
Bharata B Rao (5):
powerpc: Define Expropriation interrupt bit to VPA byte offset 0xB9
KVM: PPC: Add support for KVM_REQ_ESN_EXIT
KVM: PPC: Book3S: Enable setting SRR1 flags for DSI
KVM: PPC: BOOK3S HV: Async PF support
pseries: Asynchronous page fault support
