yep that's fine. The downside of them being modules is that to use NX 842 with zswap - which requires configuration to all be done at boot time (currently, I have patches pending to change that) - the initramfs has to be rebuilt with the NX 842 modules. But that's not a big deal, just creating a dracut.d conf file and rerunning dracut. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1454687 Title: add NX 842 hw compression patches To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1454687/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
