Subject: [PATCH 18/28] docs: kvm: convert arm/hyp-abi.txt to ReST
Date: Mon, 10 Feb 2020 07:02:56 +0100 [thread overview]
Message-ID: <f0ecf7be020cb410ee29f506d440b32e549d569a.1581314317.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1581314316.git.mchehab+huawei@kernel.org>
- Add proper markups for titles;
- Adjust whitespaces and blank lines to match ReST
needs;
- Mark literal blocks as such.

Unless specified otherwise, any built-in hypervisor must implement

Set HVBAR/VBAR_EL2 to 'vectors' to enable a hypervisor. 'vectors'

of the architecture. Only implemented by the initial stubs, not by
Linux hypervisors.

Turn HYP/EL2 MMU off, and reset HVBAR/VBAR_EL2 to the initials
stubs' exception vector value. This effectively disables an existing
hypervisor.
