Public bug reported: [Impact] Current hisi_sec2 driver only allows 2 threads for accelerator but cpu stress test requires more then 50 threads. We have disabled hisi_sec2 temporarily for 20.04.1. Hisilicon proposes a simple patch on upstream mailing list to enlarge the capability.
[Fix] https://www.mail-archive.com/linux-crypto@vger.kernel.org/msg43093.html [Test] $ lsmod | grep hisi_sec2 # make sure hisi_sec2 loaded $ sudo stress-ng --aggressive --verify --timeout 330 --metrics-brief --tz --times --af-alg 0 $ echo $? [Regression Potential] This driver is only loaded on Hisilicon Hi1620 machines.
