linux-toradex.git/drivers/misc/sgi-gru, branch v2.6.30-rc8 Linux kernel for Apalis and Colibri modules sgi-xp/sgi-gru: allow modules to load on non-uv systems 2009-04-21T20:41:50+00:00 Robin Holt holt@sgi.com 2009-04-21T19:24:53+00:00 e873cff0fada2b0532ca5104d5b5f5b02aa442b2 For an upcoming distro release, we need to have the xp kernel module loadable even when not on UV equipment. The xpc module will not load. This will allow one set of modules dependent upon xp to work on either UV or non-UV equipment.
