Development is begining to provide support for ARM 64 bit CPUs using the aarch64 architecture.
**Don't download yet, watch for the release announcement**
This is provided as source code only and may be built on native Linux or following the existing procedure subject to the modifications detailed below.

The miner compiles and runs on Raspberry Pi 4B, and compiles for all version of armv8 with our without AES or SHA2 or both.
What works:
* All algorithms ecept Verthash should be working, Hodl is untested and unknown.
* Allium ,Lyra2z & Lyraz330, Argon2d are fully optimzed for NEON, Allium also for AES.

* Unoptimized: Sha256dt, sha256t, Blake2s.
* Yespower, Yescrypt, Scrypt are working for with slow sha256.

* Other algos are not optimized for ARM and not tested.
* stratum+ssl and stratum+tcp are working, GBT is untested.
* CPU and SW feature detection and reporting is working, algo features in progress, CPU brand not yet implemented.
* CPU temperature and clock frequency is working.

Known problems:
* No detection of CPU model, default info displayed.
* No detection of ARM minor version number.
* No detection of ARM architecture minor version number.
* NEON may not be displayed in algo features for some algos that may support it.
* Algos may show support for NEON even if it's disabled or not yet implemented.
* AES & SHA2 are enabled but untested.
* There is no working version of Verthash on ARM, even pure compiled C code. The same code compiled for x86_64 works.
* Sha256 & Sha512 Parallel N-way are disabled. They work on X86_64.
* AES & SHA2 are enabled but untested.* Sha256 & Sha512 Parallel N-way are disabled. They work on X86_64.
* Sha256dt, Sha256t, Sha256d unoptimized.
* Scryptn2 optimzations disabled due to Sha256 issues.
* X17, MinotaurX are partially optimized.
* Blake256, Blake512, Blake2s, Blake2b N-way parallel hash not working, using liner when possible, unoptimzed otherwise.
* Blake256, Blake512, Blake2s, Blake2b N-way parallel hash not working, using linear when possible, unoptimzed otherwise.
* Simd: Multiple issues with NEON, using unoptimized.
* Luffa: NEON not working, using unoptimized
* Fugue: Multiple issues with NEON & AES, using unoptimized.
* SWIFFTX: Multiple issues with NEON,using unoptimized.
* Remaining algos are not yet optimized for NEON but should work unoptimized.
Goal for next release:
* get as many algos as practical working even if optimizations need to be disabled,
* address some of the disabled optimizations,
* enable SHA2, and AES for Groestl & Echo, untested.
