From 3bdbb62fe97537252b22f700009863eeb51aa750 Mon Sep 17 00:00:00 2001 From: Alexandre Bounine Date: Wed, 3 Jul 2013 15:08:58 -0700 Subject: rapidio: add udev notification Add RapidIO-specific modalias generation to enable udev notifications about RapidIO-specific events. The RapidIO modalias string format is shown below: "rapidio:vNNNNdNNNNavNNNNadNNNN" Where: v - Device Vendor ID (16 bit), d - Device ID (16 bit), av - Assembly Vendor ID (16 bit), ad - Assembly ID (16 bit), as they are reported in corresponding Capability Registers (CARs) of each RapidIO device.
