12 | * This header file is used by the iSeries virtual I/O device | ||
13 | * drivers. It defines the interfaces to the common functions | ||
14 | * (implemented in drivers/char/viopath.h) as well as defining | ||
15 | * common functions and structures. Currently (at the time I | ||
16 | * wrote this comment) the iSeries virtual I/O device drivers | ||
17 | * that use this are | ||
18 | * drivers/block/viodasd.c | ||
19 | * drivers/char/viocons.c | ||
20 | * drivers/char/viotape.c | ||
21 | * drivers/cdrom/viocd.c | ||
22 | * | ||
23 | * The iSeries virtual ethernet support (veth.c) uses a whole | ||
24 | * different set of functions. | ||
