Sorry for the late reply. I was busy within these days. I've seen you have merged it, I'll test the latest compiled kernel, if I found any issue, I'll reply to this topic. Thank you

Thanks for your help These items are bool, so there is a typo on your changes, it should use "y" instead of "m". I've compiled the kernel with enable these configuration items for testing. With new kernel, hardware acceleration of hash and PRNG are working. About TRNG, I don't have H6 board so I can't test it, but it should work. ==== Tested with Allwinner H5 @ 1.3GHz (NanoPi NEO Plus2) Custom compiled OpenSSL 1.1.1f (enable afalg & devcrypto) Hardware acceleration using devcrypto engine: type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes md5 125.41k 492.89k 1973.08k 7892.65k 34665.81k 69555.54k sha1 130.07k 514.35k 2055.51k 8212.48k 66057.56k 130498.56k sha224 117.82k 493.03k 1927.34k 7808.00k 62761.64k 123442.52k sha256 113.03k 464.36k 1863.77k 7758.51k 61401.77k 128270.34k Hardware acceleration using af-alg engine: md5 122.03k 487.08k 1945.43k 7781.72k 34679.47k 71068.33k sha1 128.31k 523.97k 2096.81k 8388.95k 66704.73k 117396.82k sha224 122.69k 490.47k 1933.57k 7881.05k 61666.65k 122350.25k sha256 124.84k 502.57k 2017.62k 8225.45k 63477.08k 112044.71k Hardware PRNG: # kcapi-rng -b 100000000000 | rngtest -c 1000 rngtest 5 Copyright (c) 2004 by Henrique de Moraes Holschuh This is free software; see the source for copying conditions.

Hi, Linux 5.10 has supported hardware PRNG, SHA, MD% for all sun8i-ce (H3/R40/A64/H5/H6) boards, and supported hardware TRNG on H6. Please consider enable CONFIG_CRYPTO_DEV_SUN8I_CE_HASH, CONFIG_CRYPTO_DEV_SUN8I_CE_PRNG, CONFIG_CRYPTO_DEV_SUN8I_CE_TRNG for hardware offload support. Thanks.
