=Comment: #0================================================= Emily J. Ratliff <ratliff.com> - 1. Feature Overview: Feature Id: [201167] a. Name of Feature: Linux to add Call Home data b. Feature Description This request is for Red Hat to integrate a kernel patch that implements the sclp_cpi_sysfs interface for s390x. The sclp_cpi sysfs interface allows the association of a set of descriptive data called 'Control Program Identification' (CPI) with an operating system instance (currently LPAR only). This information is not persistent and has to be set once per IPL. CPI data will be visible at the HMC/SE. CPI information is also referred to as 'Call Home data' in some contexts. CPI information could previously be set by loading the sclp_cpi kernel module. This item implements a new CPI interface in sysfs which complements the existing one. The new interface was included in Linux kernel 2.6.25. These sysfs-attributes can be used to specify the CPI information locally: /sys/firmware/cpi/system_name String: arbitrary, user-specified system name (e.g. LPAR12) /sys/firmware/cpi/sysplex_name String: arbitrary, user-specified sysplex name (e.g. SYSPLEX1) /sys/firmware/cpi/system_type String: operating system type identifier - must be 'LINUX ' /sys/firmware/cpi/system_level Hex: operating system version information, should be 0x0000000000aabbcc, where aa=kernel version, bb=kernel patch level, cc=kernel sublevel. Example: Linux kernel 2.6.26 -> 0x000000000002061a Once all attributes are filled, write an arbitrary string to this attribute to finalize the data (i.e. to send it to the SE): /sys/firmware/cpi/system_set Distributor installation/setup tools need to be changed to provide users with the ability: ? to specify whether they want to set this data ? to enter the actual data values (only 'system_name' and 'sysplex_name', since 'system_type' and 'system_level' should be set automaticly by the system) Using a distributor specific mechanism (e.g. init script), this information needs to be passed to the sclp_cpi sysfs interface during IPL, depending on the configuration. 2.

Updating PM score.
Please do not forget to update documentation and/or release notes, as mentioned in eSDT call: More details under: ??? ???Control program identification??? in latest version of Device Drivers, Features, and Commands at: http://www.ibm.com/developerworks/linux/linux390/development_documentation.html
in kernel-2.6.18-138.el5 You can download this test kernel from http://people.redhat.com/dzickus/el5 Please do NOT transition this bugzilla state to VERIFIED until our QE team has sent specific instructions indicating when to do so. However feel free to provide a comment indicating that this fix has been verified.
This enhancement request was evaluated by the full Red Hat Enterprise Linux team for inclusion in a Red Hat Enterprise Linux minor release. As a result of this evaluation, Red Hat has tentatively approved inclusion of this feature in the next Red Hat Enterprise Linux Update minor release. While it is a goal to include this enhancement in the next minor release of Red Hat Enterprise Linux, the enhancement is not yet committed for inclusion in the next minor release pending the next phase of actual code integration and successful Red Hat and partner testing.
Release note added. If any revisions are required, please set the "requires_release_notes" flag to "?" and edit the "Release Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team.

In IBMs feature description I see: Distributor installation/setup tools need to be changed to provide users with the ability: ? to specify whether they want to set this data ? to enter the actual data values (only 'system_name' and 'sysplex_name', since 'system_type' and 'system_level' should be set automaticly by the system) However, I don't see commends reflecting this change was made in Anaconda or init scripts. Has this piece been integrated in?
