Subject: [PATCH v2 00/94] KVM: arm64: ARMv8.3/8.4 Nested Virtualization support
Date: Tue, 11 Feb 2020 17:48:04 +0000 [thread overview]
Message-ID: <20200211174938.27809-1-maz@kernel.org> (raw)
This is a major rework of the NV series that I posted over 6 months
ago[1], and a lot has changed since then:
- Early ARMv8.4-NV support
- ARMv8.4-TTL support in host and guest
- ARMv8.5-GTG support in host and guest
- Lots of comments addressed after the review
- Rebased on v5.6-rc1
- Way too many patches
In my defence, the whole of the NV code is still smaller that the
32bit KVM/arm code I'm about to remove, so I feel less bad inflicting
this on everyone! ;-)
From a functionality perspective, you can expect a L2 guest to work,
but don't even think of L3, as we only partially emulate the
ARMv8.{3,4}-NV extensions themselves. Same thing for vgic, debug, PMU,
as well as anything that would require a Stage-1 PTW. What we want to
achieve is that with NV disabled, there is no performance overhead and
no regression.
The series is roughly divided in 5 parts: exception handling, memory
virtualization, interrupts and timers for ARMv8.3, followed by the
ARMv8.4 support. There are of course some dependencies, but you'll
hopefully get the gist of it.
For the most courageous of you, I've put out a branch[2]. Of course,
you'll need some userspace. Andre maintains a hacked version of
kvmtool[3] that takes a --nested option, allowing the guest to be
started at EL2. You can run the whole stack in the Foundation
model. Don't be in a hurry ;-).
