Title: [21.04 FEAT] NVMe IPL Load Normal support - kernel Status in Ubuntu on IBM z Systems: Fix Released Status in linux package in Ubuntu: Fix Released Bug description: Re-IPL for NVMe is currently done by using diag 308 with the "Load Clear" subcode, which means that all memory will be cleared. This can increase re-IPL duration considerably on very large machines. For list-directed IPL like NVMe or FCP IPL, a "Load Normal" subcode was introduced with z14. The "Load Normal" diag 308 subcode allows to re-IPL without clearing memory. This feature adds kernel and s390-tools support for a new "clear" sysfs attribute in /sys/firmware/reipl/nvme, which can be set to either "0" or "1" to disable or enable re-IPL with memory clearing. The default value is "0", which disables memory clearing. Feature request for kernel contribution. Target kernel >= 5.9. Therefore a backport need to be provided To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1887921/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
