Kernel 2.6 based: October 2005 stream

 

Overview: "October 2005 stream": Archive

          *** This archive-page is superseded ***

The recommended downloads from this page were tested with the following levels of open source kernel, tool-chain, utilities, and debug tools - which can be used to build Linux on System z9 and zSeries distributions:

  • kernel 2.6.13
    • including kerntypes and OCO module tape_3590
  • tool-chain:
    • binutils 2.15.94.0.2.2
    • gcc 4.0.2
    • glibc 2.3.5
  • utilities:
    • s390-tools 1.5.1
  • debug tools:
    • gdb 6.3
    • strace 4.5.12
    • lkcdutils as of LKCD version 6.0.0 (CVS HEAD)

2005-12-09 Upgrade:

  • s390-tools 1.5.1 with bug fixes replaces s390-tools 1.5.0

2005-10-14 Introducing the "October 2005 stream":

The "October 2005 stream" uses mostly up-stream code and requires comparatively few and small patches from developerWorks, and contains:

  • applicable features and bug-fixes provided for the "April 2004 stream"
  • kernel 2.6.13 features, of which - from the Linux on System z9 and zSeries perspective - the following items are of special interest:
    • Improved kernel machine check handling
    • Optimization of the s390 debug feature
    • Adjustment of CPU accounting
    • Kernel-support for user space access to CP commands (via vmcp in s390-tools 1.5)
    • The infrastructure for execute-in-place in memory management, virtual file system layer, and block device layer is provided in kernel 2.6.13 (and no longer needs to be added per separate patch as in the "April 2004 stream"). EXT2 now exploits the execute-in-place infrastructure.
    • DASD support for write barriers
  • Hardware Support for IBM System z9 features (refer to IBM U.S. Hardware Announcement Letter 105-241):
    • Linux support for OSA-Express2 OSN - Open Systems Adapter for NCP (CDLC support)
    • Linux support for N-Port-ID Virtualization (NPIV)
    • Linux support for (FCP) Program-directed re-IPL
    • Linux support for Configurable Crypto Express2 Accelerator (CEX2A support, PCIXCC fast path)
  • Virtual Server
    • Support for z/VM 5.2 new 64-bit dump format (refer to IBM U.S. Software Announcement Letter 205-168) via enhanced vmconvert (in s390-tools 1.5.0)
    • vmcp: new kernel module allowing user space access to CP commands (via s390-tools 1.5.0 new component vmcp)
  • Other:
    • zfcp debug and tracing improvements
    • zfcp performance statistics
  • s390-tools 1.5.0
    • vmconvert: now supports new 64-bit z/VM 5.2 dump format
    • vmcp: new tool allowing user space access to CP commands
    • zfcpdbf: new perl script to filter ZFCP debug data
    • zfcpdump: upgraded to recent kernel-level
    • DASD tools: usability enhancements
  • HBA API library 1.3.0
    • new SAN discovery and zfcp configuration tool san_disc
