Linux Patches Updated For Experimental Arm Morello That Combines Arm + CHERI ISA
Arm today sent out their third iteration of their Linux kernel patches for adding Arm Morello platform support to the kernel: an experimental extension of Armv8.2-A paired with the CHERI v7 ISA.
Arm Morello is a research program with the UK government for a new security architecture based on CHERI (Capability Hardware Enhanced RISC Instructions). The recent flow of Morello platform patches have been rebasing against newer versions of the kernel Git state and addressing review comments. These patches under review for mainlining are just around the DeviceTree support for this developer platform and not any kernel-user ABI changes or other architectural modifications for Morello with its combined ARM+CHERI ISA.
