Thanks, I've been looking into updating these. > o Change CONFIG_ACPI_NFIT=y to CONFIG_ACPI_NFIT=m. > o Enable CONFIG_SCHED_SMT for hyperthreading processors. > o Enable CONFIG_ARM64_LSE_ATOMICS for v8.1 processors. > o Enable a number of ACPI options likely to be available on servers. > o CONFIG_ACPI_APEI selects PSTORE, so remove the arm64 specific setting. ACPI_APEI breaks HP m400, the xgene moonshot: https://bugzilla.redhat.com/show_bug.cgi?id=1574718 The rest of options are generally fine. Wish more of these were modules tho. If we ok with telling M400 users to setting kernel command line of ghes.disable=1, we can enable APEI as well. > 0001-arm64-Use-default-of-CONFIG_ACPI_NFIT-m.patch > 0002-arm64-Updates-for-ACPI-servers.patch > > > -- System Information: > Debian Release: buster/sid > APT prefers testing > APT policy: (500, 'testing') > Architecture: arm64 (aarch64) > > Kernel: Linux 4.16.12 (SMP w/224 CPU cores) Cheeky.
