So, on RHEL/CentOS kernels, there are three new entries in /sys/kernel/debug/x86; ibpb_enabled, ibrs_enabled, and pti_enabled. I don't see these on the Fedora kernel. Are these variables something added by Red Hat to their kernel, something that will be added to Fedora, etc.? They are useful to see exactly what fix(es) are being applied, as well as to have a runtime way to enable/disable them. -- Chris Adams <linux@xxxxxxxxxxx> _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
