The hardware does not have separate interrupts per queue. Working interrupt mode driver.* Computes SHA hashes, HMAC. Passes cryptotest.py, cryptocheck tests.* Does AES-CBC, CTR mode, and XTS. cryptotest.py and cryptocheck pass.* Support for "authenc" (AES + HMAC). (SHA1 seems to result in "unaligned" cleartext inputs from cryptocheck -- which the engine cannot handle. SHA2 seems to work fine.)* GCM passes for block-multiple AAD, input lengthsLargely based on ccr(4), part of cxgbe(4).Rough performance averages on AMD Ryzen 1950X (4kB buffer):aesni: SHA1: ~8300 Mb/s SHA256: ~8000 Mb/sccp: ~630 Mb/s SHA256: ~660 Mb/s SHA512: ~700 Mb/scryptosoft: ~1800 Mb/s SHA256: ~1800 Mb/s SHA512: ~2700 Mb/sAs you can see, performance is poor in comparison to aesni(4) and evencryptosoft (due to high setup cost). At a larger buffer size (128kB),throughput is a little better (but still worse than aesni(4)):aesni: SHA1:~10400 Mb/s SHA256: ~9950 Mb/sccp: ~2200 Mb/s SHA256: ~2600 Mb/s SHA512: ~3800 Mb/scryptosoft: ~1750 Mb/s SHA256: ~1800 Mb/s SHA512: ~2700 Mb/sAES performance has a similar story:aesni: 4kB: ~11250 Mb/s 128kB: ~11250 Mb/sccp: ~350 Mb/s 128kB: ~4600 Mb/scryptosoft: ~1750 Mb/s 128kB: ~1700 Mb/sThis driver is EXPERIMENTAL. You should verify cryptographic results ontypical and corner case inputs from your application against a known- goodimplementation.Sponsored by: Dell EMC IsilonDifferential Revision: https://reviews.freebsd.org/D12723 List of files: /freebsd/sys/modules/ccp/Makefile Thu, 18 Jan 2018 23:01:30 +0100 Conrad Meyer <cem@FreeBSD.org>
