Subject: zdev: Add support for handling I/O configuration data
|
|
From: Peter Oberparleiter <oberpar@linux.ibm.com>
|
|
|
|
Summary: zdev: Add support for handling I/O configuration data
|
|
Description: LPARs that are running in IBM Dynamic Partition Manager (DPM) mode
|
|
can access a firmware-generated I/O configuration data file that
|
|
contains s390-specific information about available I/O devices
|
|
such as qeth device numbers and parameters, and FCP device IDs.
|
|
|
|
This data file is intended to remove the need for users to
|
|
manually enter the corresponding device data during installation.
|
|
|
|
Linux kernels with the corresponding support make the I/O
|
|
configuration data available at the following location:
|
|
|
|
/sys/firmware/sclp_sd/config/data
|
|
|
|
This patch set adds support for handling this data file using the
|
|
chzdev and lszdev tools:
|
|
|
|
- I/O configuration data can be applied using chzdev's --import
|
|
option
|
|
- Initial RAM-Disk scripts automatically apply the
|
|
I/O configuration data to the system configuration
|
|
- lszdev can be used to display the applied auto-configuration
|
|
data
|
|
- chzdev can be used to manually override the
|
|
auto-configuration data
|
|
|
