(please CC me, I'm not subscribed) Hi, I'm wondering whether it'd make sense for the Debian kernel to be built with CONFIG_PREEMPT_DYNAMIC=y. Sorry if I have missed existing discussion on that topic but I haven't found any. Context: I'm maintaining a fork of the Debian linux kernel (thank you so much for your amazing work!) with a couple of patches and config options on top so that the Debian kernel can work on the imx8mq, imx8mplus, bananapi a311d and ls1028 SoM for the MNT Reform open source laptop. A user suggested that we also enable PREEMPT_DYNAMIC for our custom kernel builds: https://source.mnt.re/reform/reform-debian-packages/-/merge_requests/18 I do not have enough insight to make this choice and was wondering whether it would make sense for the Debian kernel to be built with that option enabled? And if not: why is it not done? As far as I understand its documentation, the option is meant for distros to enable it so that users can choose at boot-time instead of at compile time preempt=none, voluntary or full. Thanks! cheers, josch
