montjoie: I made some tests on kernel 5.5 on NanoPi R1 (H3). With sun8i-ce driver, on cbc(aes) with 256 bit keys, I am getting at most about 3.5Mbps with bandwidth controlled iperf3. If I let iperf3 to try and maximize the bandwidth, H3 completely stalls and I have to power cycle it.
<grey-bit>
montjoie: is it reasonable that CE would limit to 3.5Mbps?
<grey-bit>
montjoie: there is also a bug during "rmmod sun8i-ce" getting non-fatal null dereference each and every time.

momtjoie: meanwhile, generic crypto with AH: SHA256 and ESP: AES-CBC-256 on 1.3Ghz H3 goes all the way up to 70Mbps encryption and 50Mbps decryption - utilizing one full core.
<grey-bit>
montjoie: I am not looking for acceleration and is ok with some slowdown, but 20x is a little bit harsh... If that's what CE can really do, then it's truly useless.

and BTW, there is a gcm.ko which successfully loads, but it doesn't cause gcm(aes) to show in /proc/crypto - I am still wondering what it is for..

KotCzarny: booooooooo! i just realized that the boxes of orange pi i brought home were all of opi +2e !!! unless i *need* COMPUTING POWER
<ullbeking>
or a real SATA interface, these serve perfectly as little machines, esp at home
<ullbeking>
am going to try building another cluster when i get more money
<ullbeking>
KotCzarny: in other words, i don't have any OPi Zero Rev. 4 to do those temperate experiments on

any idea if it'd be practical to make a few custom PinePhones? :x

grey-bit the bug with rmmod is fixed and should land in stable
<montjoie>
grey-bit I expect better performance, but on H3 the sun8i-ce is less performant

montjoie: thanks. Do you think that 3.5Mbps on H3 is roughly about what should be expected from this hardware or may be I am doing something wrong here? I can't imagine what Allwinner guys would plan to do with some minuscule throughput......

grey-bit: I am not sure I even understand your question
<[TheBug]>
Are you talking about network throughput?
<[TheBug]>
and if so, via ethernet or wifi
<KotCzarny>
maybe it could be used as an accelerator for arisc

[TheBug]: I am trying to utilize H3 crypto engine for offloading AES-CBC-256 (kernel 5.5). It's maxing out at 3.5Mbps of encryption..
