Hello,
i'm experimenting Tor setup on very cheap servers from scaleaway.com that run a quad-core ARM Marvell Armada 370/XP servers but have unlimited bandwidth.
Those are Soc platform: http://natisbad.org/NAS2/refs/Marvell_ARMADA_370_SoC.pdf
I saw no information on torproject mailing list about those SOC.
I'm trying to push the limits and i saw that those have a crypto acceleration support: https://www.kernel.org/doc/Documentation/devicetree/bindings/crypto/marvell-...
However with kernel 4.5.7 it does not really work and loading of marvel-cesa gives out error: [6.841862] marvell-cesa: probe of d0090000.crypto failed with error -22
:(
I've only built latest Tor 0.2.9 with -O9 -mcpu=marvell-pj4 -mtune=xscale and the Tor Relay is at https://atlas.torproject.org/#details/82C63C5D61D17557B7C5D0E7FDC545A2B6B6B7... .
Does someone have experienced optimizing and tuning Tor specifically on ARM processors to understand how far those could be optimized?
