Subject: [PATCH v3 00/66] KVM: arm64: ARMv8.3/8.4 Nested Virtualization support
Date: Thu, 10 Dec 2020 15:58:56 +0000 [thread overview]
Message-ID: <20201210160002.1407373-1-maz@kernel.org> (raw)
This is a rework of the NV series that I posted 10 months ago[1], as a
lot of the KVM code has changed since, and the series apply anymore
(not that anybody really cares as the the HW is, as usual, made of
unobtainium...).
From the previous version:
- Integration with the new page-table code
- New exception injection code
- No more messing with the nVHE code
- No AArch32!!!!
- Rebased on v5.10-rc4 + kvmarm/next for 5.11
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 ;-).
And to be clear: although Jintack and Christoffer have written tons of
the stuff originaly, I'm the one responsible for breaking it!
