Was reading the dmesg listings on your blog. Seems that X-gene 1 doesn't have AES instructions, is that correct?
I'm in the midst of optimizing the CryptoNight hash algorithm for ARMv8. Fortunately the Cortex-A53 in the RK3368 has AES instructions otherwise it would be pretty dismal.
- rwmj 11y agoHow to find out? /proc/cpuinfo says: Features : fp asimd evtstrm The X-gene 1 has a custom core developed by APM (called Potenza). Edit: If you mail me (_source!_) code to rjones redhat com I will run it.
- hyc_symas 11y agoWilldo, when I have something ready to test. Thanks! Here's the rk3368: geekbox@geekbox:/home/software/bitmonero/build$ cat /proc/cpuinfo processor : 0 BogoMIPS : 48.00 Features : fp asimd evtstrm aes pmull sha1 sha2 crc32 CPU implementer : 0x41 CPU architecture: AArch64 CPU variant : 0x0 CPU part : 0xd03 CPU revision : 3 (and so on for the other 7 cores)
