[PATCH] add options to udevtrigger to control scanning

[PATCH] add options to udevtrigger to control scanning

[Greg KH]

This patch has been in the gentoo tree for a bit.  It modifies
udevtrigger to allow a little more fine grained control for people who
don't want all of the sysfs tree to be scanned by udevtrigger at
startup.

Patch was originally written by Martin Schlemmer <azarah@gentoo.org> but
was forward-ported by me to the latest version of udev.

When is it useful to have such options. And "no" flags who negate
something from all events sounds pretty odd to me.
The Ubuntu guys use a patch which can filter on values to have control
over what is triggered and what not. If we are going that road, I like
their patch more than this. But in both cases, please explain in which
situations this is really needed?

Thanks,
Kay

Well, either that or force the --scan-class options to be used :)

Do you have a pointer to where this patch is?

People do not want all of their devices probed for at boot time, they
want to load the modules that they know they want, on their own.  So
they don't want all of the modalias files being poked at.

In short, they don't like the "coldplug" functionality for loading
modules and only want udev to handle the device nodes present at boot
time.  I don't blame them for wanting this because with machines that
you know all the hardware, it isn't necessary, and does speed up the
boot process ever so slightly.

And yes, they can use the blacklist functionality from
module-init-tools, except that seems to be broken right now in the
Gentoo releases, and I'm having a hard time figuring out why.  It used
to work...

So this could be reduced to just the one option, --no-scan-bus, as that
is all that Gentoo currently uses.  I think the original author was just
trying to be nice in giving all possible options :)

Would you be more comfortable with just that option being added?  The
filter seems a bit complicated, unless you are able to specify all
modalias files.

thanks,

They could also not create a rule to run modprobe, which looks cleaner
to me and does not require any new code.

But you want modprobe to run when adding a new usb device, or pcmcia
device, so that rule is necessary.  Just not at boot time which causes
the whole pci bus to be scanned, and stupid things like shpchp always to
be loaded :(

Attached;  I sent it to this list a while back as part of my "patches
collection" mail.

The reason we use this is that we try and have an initramfs that works
on every single machine, rather than produce a tailored one for the
machine underneath.

So we take a little more care about what we coldplug and when -- rather
than just probing for everything and hoping for the best.

We better avoid exposing kernel driver implementation details like
'bus', 'class', 'block', if we can. The current udev does not even have
the old BUS= key in the man page, and everything is just SUBSYSTEM(S).
That way, we are hopefully free to move things around in the kernel
without breaking too much in userspace. Also 'block' may be a 'class',
some day, and better not have its own option.

I've added these options to udevtrigger now:
  --subsystem-match=<subsystem>
  --subsystem-nomatch=<subsystem>
  --attr-match=<file[=<value>]>
  --attr-nomatch=<file[=<value>]>

If you only want to populate /dev, this should work fine:
  udevtrigger --attr-matchfiv
It will also skip all class devices which don't have a corresponding
device node.

You can also just skip all devices with a 'modalias' file:
  udevtrigger --attr-nomatch modalias
Or just skip all devices with 'modalias' for pci:
   udevtrigger --attr-nomatch modalias=pci*

By adding "--dry-run --verbose", you can check the filter on the command
line. It's in the git tree now, care to try if that works for you?

Thanks,
Kay

Very nice, I just tried this out and it works fine for me.  Nice thing
is, it sped up my boot time a bunch, as I don't have to wait on
udevtrigger to finish setting up my usb bus (or that's why I'm guessing
it's so much faster, haven't looked into it at all yet.)

thanks for doing this.

Oh, attached is the latest gentoo 50-rules.d file, if you want to update
the udev tree with it (Gentoo now uses the persistant rules file from
the udev package, so our rules file is a lot smaller now.)

thanks,

greg k-h
