Domain Creation And Runtime¶
Kernel command line arguments¶
XenProd~kernel_cmd_line_args~1
Description: Xen shall pass kernel command line arguments to a domain via a device tree.
Rationale:
Comments: Device tree is a data structure and language for describing hardware which is readable by an operating system [1].

XenMkt~run_arm64_domains~1
- Needs:
XenSwdgn
Ramdisk¶
XenProd~ramdisk~1
Description: Xen shall provide the address of an initial ramdisk to a domain via a device tree.
Rationale:
Comments: The initial ramdisk is contained in memory.

Memory¶
XenProd~memory~1
Description: Xen shall create a domain with the amount of memory specified in a device tree.

vCPUs¶
XenProd~vcpus~1
Description: A domain shall have a configurable number of virtual CPUs (1 to 128).

Credit2 CPU pool scheduler¶
XenProd~credit2_cpu_pool_scheduler~1
Description: Xen shall have a credit2 scheduler where a physical cpu can be shared between more than one virtual cpu.

XenMkt~run_arm64_domains~1
XenMkt~multiple_schedulers~1
- Needs:
XenSwdgn
NUL CPU pool scheduler¶
XenProd~nul_cpu_pool_scheduler~1
Description: Xen shall have a nul scheduler where the domain virtual cpu is always running on its dedicated physical cpu.
Rationale:
Comments: A NUL CPU pool scheduler maps a virtual cpu to a unique physical cpu.
