2010-05-28: kernel 2.6.34 - upstream (feature description)

To download the linux-2.6.34.tar.gz visit: http://www.kernel.org/pub/linux/kernel/v2.6

The upstream kernel 2.6.34 contains the following functionality developed by the Linux on System z development team:

Summary:
dasd: Automatic detection of read only DASDs
Description:
In z/VM it is possible to attach a device as read-only. To prevent unintentional write requests and subsequent I/O errors, read-only devices are now detected and the respective Linux block device is set to read-only as well.

Only applicable when running Linux on System z as a VM-guest.


Summary:
kernel: Kernel image compression
Description:
Support for compression of the kernel image file to save disk space.

Summary:
kernel: Deliver z/VM CP special messages to user space
Description:
New kernel device driver (smsgiucv_app) for receiving z/VM CP special messages (SMSG) and delivering these messages to user space as udev events (uevents). The device driver registers with the existing CP special message device driver to only receive messages starting with "APP". The created uevents contain message sender and content as environmental data.

Only applicable when running Linux on System z as a VM-guest.


Summary:
kernel: convert Linux on System z dumps to ELF
Description:
Introduce support for converting Linux on System z dumps into the Executable and Linkable Format (ELF). Previously, Linux on System z dumps were only available in s390-format or LKCD-format.

This enhancement introduces a new restriction for DASD dump devices to 4KB block size (which already is the recommended block size for DASD dump).

Note that zgetdump in s390-tools 1.9.0 can now read and write ELF dumps.


Summary:
qeth: Support for HiperSockets Network Traffic Analyzer (HS NTA)
Description:
HiperSockets Network Traffic Analyzer (also known as "HiperSockets Sniffer") is a feature available on latest z10, designed to trace HiperSockets network traffic for problem isolation and resolution purposes.

z/VM guest support for HS NTA requires z/VM 5.3, z/VM 5.4, or z/VM 6.1 with PTF for APAR VM64694.

Note that lsqeth in s390-tools 1.9.0 indicates HS NTA as "sniffer".

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

linux-2.6.34-s390-kerntypes.tar.gz / MD5 ... recommended (2010-05-28)

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-2.6.34-s390-message-catalog.tar.gz / MD5 ... recommended (2010-05-28)

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'.
