What's wrong with the current sysfs way of adding new device ids without

added that functionality, so users would not have to constantly update
their kernel. The distros provide userspace tools that enable these ids
to be added and at boot time, everything "just works" properly.
I haven't found a single distro that (a) makes it trivial to add PCI IDs at
install time, and then (b) ensures those PCI IDs remain persistent for each
boot. We are not at all to the "just works" stage yet.
Well, SuSE handles this just fine, but I do notice that RHEL 5 disables
the new_id stuff entirely, so I can see why you might get this
impression :)
So, because of that, I don't really see a need to be adding new device
ids to the -stable tree.
Maybe you are just not seeing all the developers that keep bringing this
up??
This is the second time it has occurred that I know of.
Really, it is just silly to think that one-line PCI IDs patches will cause
any harm at all, and it should be self-evident that there is clear potential
to HELP Linux users. That's why we're all here, right?
I'm not disagreeing that it will help a set of users, or that it will
cause any harm at all. It's just currently outside the scope for what
we defined -stable as, and it will slightly increase the workload that
Chris and I have in keeping up with these patches.
So, if there is an overwhelming majority of people that strongly feel
that this is a good thing, fine, we can try it out.
I'm just trying to point out that the new_id sysfs stuff is there
explicitly for this very reason, as people were demanding that (Dell
being the major company behind it.)
thanks,
