Subject: [PATCH v2 0/4] xen/arm: Prevent Dom0 to be loaded when using dom0less
Date: Thu, 8 Apr 2021 10:48:14 +0100 [thread overview]
Message-ID: <20210408094818.8173-1-luca.fancellu@arm.com> (raw)
This is the v2 of xen/arm: Prevent Dom0 to be loaded when using dom0less
previously pushed.
The aim of this serie is to prevent the creation and run of the domain 0 (Dom0)
when the system configuration to be used is dom0less, that is when the device
tree declares at least one domU and no Dom0.
Changes in v2 are:
- Moving the dom0 creation in a proper function
- Handle the case of having an hardware_domain NULL
- Be sure that the domain id 0 is never allocated
- Modify documentation about dom0less
Luca Fancellu (4):
xen/arm: Move dom0 creation in domain_build.c
xen/arm: Handle cases when hardware_domain is NULL
xen/arm: Reserve domid 0 for Dom0
