Back in the RHELSA-7 days, we decided to turn off CONFIG_DEVMEM because certain userspace tools which were not sufficiently Arm-aware would crash the kernel. Someone (Applied Micro or Cavium) complained that there was debug value in having it enabled so we enabled it in -debug kernels. With RHEL-8, we missed the addition of STRICT_DEVMEM and it defaulted to =y even though DEVMEM was turned off so it didn't matter. Now we have DEVMEM enabled on RHEL-9 non- debug kernel. If we're going to leave it enabled, we want STRICT_DEVMEM=y so it's not so easy to crash the kernel. But turning DEVMEM on only for the -debug kernel makes the most sense to me. _______________________________________________ kernel mailing list -- kernel@lists.fedoraproject.org To unsubscribe send an email to kernel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/kernel@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
