Subject: [PATCH v6 0/7] enable CAAM's HWRNG as default
Date: Wed, 8 Jan 2020 07:40:40 -0800 [thread overview]
Message-ID: <20200108154047.12526-1-andrew.smirnov@gmail.com> (raw)
Everyone:
This series is a continuation of original [discussion]. I don't know
if what's in the series is enough to use CAAMs HWRNG system wide, but
I am hoping that with enough iterations and feedback it will be.
Changes since [v1]:
- Original hw_random replaced with the one using output of TRNG directly
- SEC4 DRNG IP block exposed via crypto API
- Small fix regarding use of GFP_DMA added to the series
Chagnes since [v2]:
- msleep in polling loop to avoid wasting CPU cycles
- caam_trng_read() bails out early if 'wait' is set to 'false'
- fixed typo in ZII's name
Changes since [v3]:
- DRNG's .cra_name is now "stdrng"
- collected Reviewd-by tag from Lucas
- typo fixes in commit messages of the series
Changes since [v4]:
- Dropped "crypto: caam - RNG4 TRNG errata" and "crypto: caam -
enable prediction resistance in HRWNG" to limit the scope of the
series. Those two patches are not yet ready and can be submitted
separately later.
- Collected Tested-by from Chris
Changes since [v5]:
- Series is converted back to implementing HWRNG using a job ring
as per feedback from Horia.
Feedback is welcome!
Thanks,
Andrey Smirnov
