64-bit ARM CPU core information table

AArch64 cpu core information table

Table shows some information about cpu cores designed by Arm company (as they provide TRM documentation).

AArch32 support explained

AArch32 support column can be hard to understand so let me list used values and try to provide some descriptions.

value name	description
EL0-EL3	AArch32 support on all exception levels
EL0-EL2	AArch32 support on all exception levels except L3 (X-Gene 1/2)
EL0-EL2/3	some cpu core revisions lack EL3 (X-Gene 1/2/3)
NO/EL0-EL3	support level depends on cpu core revision (Cortex-A510)
EL0-EL3?	AArch32 support on all exception levels but needs to be confirmed (usually cores based on Arm Cortex-A designs)
EL0	AArch32 support only in userspace
NO	AArch32 is not supported at all
(empty field)	AArch32 support needs to be checked with documentation

You need AArch32 support at EL1 to run 32-bit KVM guest.

Author info

Table is maintained by Marcin Juszkiewicz — AArch64/Arm developer working at Red Hat as Linaro assignee.
