Using CRDA in combination with MDEV

Using CRDA in combination with MDEV

[Mike Looijmans]

Has anyone here ever got "crda" to work with mdev (instead of udev)?


I was getting this message again from the wireless card:

cfg80211: Calling CRDA to update world regulatory domain

Now CRDA is the answer to that, and until now, I solved it by simply compiling 
a static rules database into my kernel. Which is apparently frowned upon, so I 
went looking for a more generally accepted solution.

I noticed there's a "crda" package in OE, but it RDEPENDS on udev for no other 
reason than simply because it provides a rules file for that. And I want to 
keep using mdev.

I think it would be better to split this package, and have a "crda-udev" 
package that provides the rules file and the dependency on udev. Alternative 
is to have a PACKAGECONFIG to enable udev support.


Kind regards,

I think the PACKAGECONFIG option would cause fewer surprises (perhaps?). 
Otherwise anyone currently using the crda package with udev will now 
have to change a previously-working build (to add the new crda-udev 
package) so it can continue working. Is it possible to have the 
crda-udev package automatically selected if udev is a distro feature and 
the crda package is part of the image?
