Control: reassign -1 wireless-regdb

Thanks for this detailed and informative bug report. I think the udev
rule belongs to wireless-regdb, as the rule isn't really useful without
the regulatory db, and I don't think we want to make iw Recommend
wireless-regdb. If wireless-regdb adopts the rule then it should at
least Recommend iw, which I think makes sense.

I'm reassigning this bug to wireless-regdb, but I'm open for further
discussion.

Cheers,

Paride


Is there any progress on this? Now that debian begins stabilizing bookworm
release, there is no setregdomain mechanism included.

Fedora has a nice udev script which - if no country is set explicitly - sets
the regulatory domain from the configured time zone:

https://src.fedoraproject.org/rpms/wireless-regdb/blob/rawhide/f/setregdomain

If there should not be a hard dependency on iw, this might need a separate check
or a warning...

Best regards,
Georg

Bug#804857: linux: New feature: enable CONFIG_NO_HZ_FULL and CONFIG_RCU_NOCB_CPU/CONFIG_RCU_NOCB_CPU_NONE

[Georg Müller]

But for other configurations it is worse:

config NO_HZ_FULL
bool "Full dynticks system (tickless)"
...
 This is implemented at the expense of some overhead in user <-> kernel
 transitions: syscalls, exceptions and interrupts. Even when it's
 dynamically off.

 Say N.




Upstream commit 176b8906 changed the description regarding NO_HZ_FULL:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=176b8906c399a170886ea4bad5b24763c6713d61
