The Rpi 5 supposedly has the crypto instructions. See below:

(QUOTE from Reddit)

"@hyc

Amazing that they finally quit being cheapskates and decided to pay for the crypto instruction extension that every other ARM producer in the world has included for the past 8 years already. I wonder what changed their minds.

So it’s another Broadcom chip quadcore with only 2MB L3 cache. I.e., only enough cache to run a single RandomX thread. The other cores will be wasted.

These have always been and continue to be worthless junk. For practical use these days you need closer to 4GB RAM per core, and of course 2MB cache per core. This thing only has enough resources to utilize 1 (core."

(END QUOTE)

Although I have been able to compile Xmrig on my Rpi 4, none of your recent crypto builds worked. I finally was able to purchase an Rpi 5 from Adafruit and will try again.

I have several Orange Pi 5 boards mining Verus coin. I'll be able to check the Rpi 5 hashrate in comparison.

Apologies to the quoted Reddit user. The post is 5 months old, and from a MoneroMiniing thread. I have not done a thorough search to verify its validity.

Thanks for the follow up. It's nice to know RPi5 has crypto. I've done testing on RPi4B, definitely no crypto, OPi5 with crypto, and Apple M2 from a VM.
I can't get it to compile on native MacOS. Crypto doesn't work in the VM but that could be a VM issue. I would be surprised if M2 didn't support crypto.

R-PI MAY BE CRIPPLED--

This is an old post from "oink70", who optimized Monkins' Verushash CCminer:

"Oink70 (2 yr. ago on Reddit)

Mining Verus is impossible on any Raspberry device. The Raspberry company did not license all CPU instructions, so the required functions are not available on Raspberry branded devices. As far as I know Raspberry is the only brand that crippled the CPU, so any other ARM device should work."

I picked up your recent interest in coding for ARM processors after reading the CryptoMining-Blog post on VerusCoin (VRSC) mining. I have been able to compile XMrig and tpruvot's CPUminer-Multi on my R-pi. The above CCminer packages (Monkins & Oink70) will not compile.

I am currently mining VerusCoin on a new Orange Pi 5. Verushash and MinotaurX look like good targets for coding, if you are able to find the right functions.

Raspberry Pi 5 is scheduled to hit the market this month, I believe. The CPU runs at 2.4 GHZ.

Hope to see some fresh code to match! --scryptr

Hold off on testing, it won't compile.

I have now have a Raspberry Pi so I have to work through the build issues. More news soon.

Looking for miners with ARM CPUs.

cpuminer-opt-3.23.4, source code only, has initial support for 64 bit AArch64 CPUs with NEON, SHA2 & AES.
It's experimental and untested. It needs testers. See Wiki for details...

Got it, thanks for the answer. I will sort this out.

I don't see anything wrong with the parameters and the reject reason indicates a different problem.
It's a difficulty targetting error. This is either a miner bug or a pool bug. Since yespower has been working for years
a pool bug is likely.

If you let the miner run for a while you should see some accepted shares. You can also use -m as a workaround to increase
the target diff and filter out the lower diff shares that would be rejected.

Hello JayDDee.
Tell me how to specify the value for yespower_params.perslen = strlen(opt_param_key) in the miner;
What if perslen value is not zero? and, for example, equals 80
When specifying only three parameters, .N . r. pers there is always a rejection of the solution in the miner
When mining with the yespower algorithm.

The perslen is derived from the length of the param-key arg. If the coin spec has the length wrong (at least one instance I know of)
if effectively changes the pers string (param-key). Check out the yespower section here... https://github.com/JayDDee/cpuminer-opt/wiki/Supported--Algorithms

If you still have problems post full problem description including command line and miner output.

dual cpu with 64 cores. now I disable auto-affinity and use taskset in Ubuntu, but I haven’t figured out how to do it in Hive OS yet
how repeat for example 0x1111111111111111 for second cpu?

As I stated the mask is repeated over each group of 64 CPUs. What are you trying to do with the mask?
I'd like all the details of your setup including miner console logs, I have no experience with multiple CPUs.

Edit: avoid taskset, it doesn't appear to assign individual threads.

miner does not support affinity mask of more than 64 cores?

Correct. The CLI is limited to 64 bit integers. The 64 bit mask is repeated for CPUs 64 to 127, 128 to 191, etc.
On windows the mask used is the size of a CPU group (CPU groups not supported with prebuilt binaries) and is
repeated accordingly for each group if the group size is less than 64.

I can't think of a practical case where affinity would not be repeating pattern and require all unique bits.

If you have a CPU with more than 64 threads I would be interested in your experience.

repeated accordingly for each group if the group size is less than 64.

I can't think of a practical case where affinity would not be repeating pattern and require all unique bits.

If you have a CPU with more than 64 threads I would be interested in your experience.

miner does not support affinity mask of more than 64 cores?

cpuminer-opt-23.15 released

- Fixed x11gost (sib) algo for all architectures, broken in v3.23.4.
- ARM: Fugue AES optimizations enabled.
- ARM: quark, qubit, x11gost algos optimized with NEON & AES.

This is a major milestone in ARM support bringing NEON up to parity with SSE4.2. The focus now changes to tying up loose ends,
and fixing any bugs. The pace of new releases should return to normal levels after the frequent updates of the past 2 months.

cpuminer-opt23.12

Several bugs fixes and speed improvements for x16r family for all CPU architectures.

----

cpuminer-opt-23.11

This is a release candidate for full AArch64 support, marking the end of the Beta phase.
Fixed hmq1725 & x25x algos, SSE2 & NEON, broken in v3.23.4.
Most CPU-mineable SHA3 algos (X*) upgraded to 2-way SSE2 & NEON.

-x86_64: Fixed scrypt, scryptn2 algos SSE2.
-Fixed sha512256d algo AVX2, SSE2, NEON.
-Fixed a bug in Skein N-way that reduced performance.
-ARM: Skein algo optimized for NEON, SHA2 & SSE2.
-Skein2 algo 2-way optimized for NEON & SSE2.

cpuminer-opt-23.9 released

x86_64: fixed minotaurx crash, broken in 23.7.
ARM: #407 fix compile error due to incorrect type casting for vrev instruction argument.

Previous release:

cpuminer-opt-23.8 released

Errata: Minotaurx crashes on x86_64 since v23.7, it will be fixed in the next release.

The big news is cpuminer-opt is completely divorced from OpenSSL. It's no longer necessary to install it on Linux
and it's no longer necessary to include the libcrypto DLL file in the Windows package.

Hodl algo has been removed as well as ASM code that is no longer used. There are some improvements to AArch64
AES as well. Details and download links are available in the OP.

Update for MacOS ARM: I can't get cpuminer-opt to work on MacOS natively but it works from a Linux VM using UTM.
Performance is excellent, Mac Mini is 4x Orange Pi 5.

cpuminer-opt-23.6 released

Problems with sha256 are fixed. SHA extension are enabled on ARM but has not been tested,
All users should upgrade from v23.5. See OP for details and links.

Also a reminder that Hodl algo will be removed soon.

ARM YOURSELVES!

cpuminer-opt-23.5 is released with support for ARM CPUs.
Consult the Wiki for details, all links are in the first post of this thread.

As Beta software problems are expected with ARM CPUs. Please report them but be patient.
Priority will be given to x86_64 regressions, if any.

Crank those ARMs and start your engines.

Notice of intent to delete Hodl algorithm from cpuminer-opt.

Argon2a is already deleted and I intend to do the same with Hodl. The code is just dead weight and isn't used by any other algo.
I'd like to control bloat considering the inevitable growth resulting from the addition of ARM support.

Oh GG JayDDee, i must order an Pi now and start playing around with it Grin
