Subject: [PATCH v2 0/5] Add support running nested Microsoft Hypervisor
Date: Wed, 2 Nov 2022 16:35:57 +0000 [thread overview]
Message-ID: <cover.1667406350.git.jinankjain@linux.microsoft.com> (raw)
In-Reply-To: <https://lore.kernel.org/linux-hyperv/cover.1667394408.git.jinankjain@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):
mshv: Add support for detecting nested hypervisor
hv: Setup synic registers in case of nested root partition
hv: Add an interface to do nested hypercalls
hv: Enable vmbus driver for nested root partition
hv, mshv : Change interrupt vector for nested root partition
