2010-03-12: kernel 2.6.33 - upstream (feature description)

To download the linux-2.6.33.tar.gz visit: http://www.kernel.org/pub/linux/kernel/v2.6

The upstream kernel 2.6.33 contains the following functionality developed by the Linux on System z development team:

Summary:
cio, dasd: Improved DASD error recovery
Description:
Improved the DASD error recovery procedures used in the early phases of IPL and DASD device initialization.

Summary:
qeth: OSA QDIO Data Connection Isolation
Description:
The 'OSA-Express QDIO data connection isolation' feature (available for OSA-Express2 cards since early 2009) allows an operating system to configure the OSA adapter to prevent any direct package exchange between itself and other operating system instances that share the same OSA adapter.

With kernel 2.6.33, Linux on System z instances can activate QDIO data connection isolation. The configuration of the isolation level is done through sysfs.

Starting with s390-tools 1.8.4 lsqeth indicates connection isolation in qeth attribute 'isolation'.


Summary:
zcrypt: Support for Crypto Express3 (CEX3A, CEX3C)
Description:
Support for Crypto Express3 Accelerator (CEX3A) and Crypto Express3 Coprocessor (CEX3C) - which previously were 'tolerated' as CEX2A/CEX2C, including support for special commands on the secure key path.

z/VM 6.1, 5.4, or 5.3 with the PTF for APAR VM64656 is required for z/VM guest-support.

2010-03-12: "Development Stream" kernel 2.6.33 kerntypes (feature - optional patch)

linux-2.6.33-s390-kerntypes.tar.gz / MD5 ... recommended (2010-03-12)

This patch contains:

Summary:
Kernel types for lcrash dump analysis.
Description:
Add a dummy module that contains all relevant kernel types that the dump analysis tool lcrash needs. The kernel type information is used as input by the lcrash utility when analysing system crash dumps or the live system.

This patch is optional as it is very unlikely to be accepted in upstream kernel, but is recommended for all distributions which are built based on the 'Development stream'.

2010-05-28: "Development Stream" kernel 2.6.34 message catalog (feature - optional patch)

linux-2.6.33-s390-message-catalog.tar.gz / MD5 ... recommended (2010-03-12)

This patch contains:

Summary:
Kernel message catalog.
Description:
Add support for automatic message tags to the printk macro families dev_xyz and pr_xyz. The message tag consists of a component name and a 24 bit hash of the message text. For each message that is documented in the included kernel message catalog a man page can be created with a script (which is included in the patch). The generated man pages contain explanatory text that is intended to help understand the messages.

Note that only s390 specific messages are prepared appropriately and included in the generated message catalog.

This patch is optional as it is very unlikely to be accepted in upstream kernel, but is recommended for all distributions which are built based on the 'Development stream'.
