Hi guys, Do you know if M1 chip implements the EL3 or not? What's the ARM spec for it, ARMV8-A or more precision for the extension version like v8.x-A? PS: I am very curious about the M1 name, where does this name 'M1' comes from?

The RN of macOS 11 beta 6 said that "In macOS 11 and later, the kernel doesn’t load a kext if an equivalent System Extension solution exists. You may continue to use kexts in macOS 10.15 and earlier" The equivalent System Extension is so subjective, how to understand the exact meaning of the 'equivalent' here with a little bit objective syntax? IOW: what's the essential indicator of the 'equivalent' between the sysext and kext?

I have a piece of code which can be build successfully in xcode 10.x version, but today the code build failed after I grade the xcode to 11.1 version, so I want to see if there's xcode version macro can be used in build phase, like this:#if XCODE_SDK_MAJ_VERSION <11 code line 1 code line 2#else code line 2#endifAny comments?
