Subject: [PATCH v3 0/5] Add support running nested Microsoft Hypervisor
Date: Thu, 3 Nov 2022 13:04:02 +0000 [thread overview]
Message-ID: <cover.1667480257.git.jinankjain@linux.microsoft.com> (raw)
In-Reply-To: <https://lore.kernel.org/linux-hyperv/cover.1667406350.git.jinankjain@linux.microsoft.com/T/#t>
This patch series plans to add support for running nested Microsoft
Hypervisor. In case of nested Microsoft Hypervisor there are few
privileged hypercalls which need to go L0 Hypervisor instead of L1
Hypervisor. This patches series basically identifies such hypercalls and
replace them with nested hypercalls.
Jinank Jain (5):
x86/hyperv: Add support for detecting nested hypervisor
Drivers: hv: Setup synic registers in case of nested root partition
x86/hyperv: Add an interface to do nested hypercalls
Drivers: hv: Enable vmbus driver for nested root partition
x86/hyperv: Change interrupt vector for nested root partition
