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. Low risk for other platform. ** Affects: linux (Ubuntu) Importance: Undecided Assignee: Ike Panhc (ikepanhc) Status: In Progress ** Affects: linux (Ubuntu Focal) Importance: Undecided Assignee: Ike Panhc (ikepanhc) Status: In Progress ** Affects: linux (Ubuntu Groovy) Importance: Undecided Assignee: Ike Panhc (ikepanhc) Status: In Progress ** Also affects: linux (Ubuntu Groovy) Importance: Undecided Assignee: Ike Panhc (ikepanhc) Status: In Progress ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Focal) Status: New => In Progress ** Changed in: linux (Ubuntu Focal) Assignee: (unassigned) => Ike Panhc (ikepanhc) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1890222 Title: Enlarge hisi_sec2 capability To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1890222/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
