From: Marc Zyngier <marc.zyngier@arm.com> To: linux-arm-kernel@lists.infradead.org, kvmarm@lists.cs.columbia.edu, kvm@vger.kernel.org Cc: Andre Przywara <andre.przywara@arm.com>, Dave Martin <Dave.Martin@arm.com> Subject: [PATCH 00/59] KVM: arm64: ARMv8.3 Nested Virtualization support Date: Fri, 21 Jun 2019 10:37:44 +0100 [thread overview] Message-ID: <20190621093843.220980-1-marc.zyngier@arm.com> (raw) I've taken over the maintenance of this series originally written by Jintack and Christoffer. Since then, the series has been substantially reworked, new features (and most probably bugs) have been added, and the whole thing rebased multiple times. If anything breaks, please blame me, and nobody else. As you can tell, this is quite big. It is also remarkably incomplete (we're missing many critical bits for fully emulate EL2), but the idea is to start merging things early in order to reduce the maintenance headache. What we want to achieve is that with NV disabled, there is no performance overhead and no regression. The only thing I intend to merge ASAP is the first patch in the series, because it should have zero effect and is a reasonable cleanup. The series is roughly divided in 4 parts: exception handling, memory virtualization, interrupts and timers. 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[1] containing this and a bit more. Of course, you'll need some userspace. Andre maintains a hacked version of kvmtool[1] 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 ;-).
