Hardware support for the Arm Memory Tagging Extension (MTE)

Note: Content on this page is under development. It might not be accurate or outdated.

Please refer to the column “MTE supported” to see if Arm Memory Tagging Extension (MTE) is available on this chipset. MTE was introduced with ARMv8.5 and became mandatory with ARMv9. However, that doesn’t mean that all chipsets supporting ARMv9 and later support MTE.
