Linus Torvalds and Andrew Morton Release Linux Kernel 2.6 Test9 Version Call for Broad Industry Testing of Pre-Production Linux Kernel in Enterprise

Environments and by Independent Software Vendors

    BEAVERTON, Ore., Oct. 27 /PRNewswire/ -- The Open Source Development Labs
 (OSDL), a global consortium of leading technology companies dedicated to
 accelerating the adoption of Linux, today announced the release of a new 2.6
 Linux test kernel version from Linux creator Linus Torvalds and 2.6 kernel
 maintainer Andrew Morton that is ready for enterprise testing.
     The software release -- available on the Web at or -- is called the test9 release version of the Linux 2.6 kernel.
 It is a significant milestone in the development of the final production
 version of the new 2.6 Linux kernel.  OSDL is calling on major Linux
 customers, independent software vendors (ISVs) and leading systems providers
 to target the test9 release version for testing, validation and enhancement to
 prepare for the next production release of Linux.
     "Now is when we want big companies and software vendors to step in and
 hammer on the kernel so we can get their ideas into the final production
 release of 2.6 Linux," said OSDL Fellow Linus Torvalds. "This is their last
 big chance."
     When Torvalds and Morton released the first 2.6 kernel test version in
 July, they established stable APIs, including Posix and thread interfaces.
 OSDL has performed a non-stop series of performance and regression tests on
 the kernel at its data center test Lab facilities in Portland, Oregon and
 Yokohama, Japan.
     The Lab's Linux test infrastructure consists of OSDL's Scalable Test
 Platform (STP) and Patch Lifecycle Manager(PLM) systems, plus a compile
 regression test platform. The Lab publishes testing results online at
     The OSDL testing infrastructure automatically tracks the progress of
 kernel development, checking new patches when they are released. OSDL has
 created a set of database workload tests based on Fair Use implementation of
 key Transaction Processing Council (TPC) tests, and provides source code for
 other test suites, including an updated version of the AIM7 and AIM9 tests.
 All OSDL test code is freely available under an open source license. OSDL is
 continuously performing tests on enterprise hardware configurations and
 publishes those results online at The Lab encourages users
 of the Linux-2.6.0-test9 to take advantage of OSDL test workloads, available
 online at OSDL or on Sourceforge, and to report back on their experiences and
     "The new 2.6 Linux kernel really broadens the markets where Linux can
 replace legacy platforms," said Timothy Witham, OSDL Lab director. "It has key
 new features that allow Linux to scale dramatically up to support 32 or more
 processors and down to run in a wide variety of consumer and industrial
 devices, including hundreds of new low-cost embedded processors."
     Among the major improvements in the new 2.6 kernel compared to the current
 production 2.4 Linux kernel released in January 2001 are:
      1.   Improved scalability.  It has been tested on up to 64-way systems.
           It is ready for production use on 32-way machines.  Added new CPU
           scheduler, memory management and file system code.  Supports up to
           8Gb of memory on IA-32 systems.
      2.   Faster threading.   New Native Posix Thread Library for Linux
           (NPTL) results in test times on 100,000 threads reduced from 15
           minutes to 2 seconds for significantly faster system performance
           under heavy loads.
      3.   Enhanced driver layer.  I/O devices such as disks perform better
           and are easier to manage.  New features include: Logical Volume
           Management (LVM), sysfs, device mapper, reduced lock contention.
      4.   Support for many more embedded device applications.  uClinux
           integration brings new support for low-cost, low-power CPUs without
           memory management units which are commonly used in embedded devices.
      5.   Improved desktop features.  Hot plug devices, including firewire
           and USB, are dramatically improved.  Mouse, video, and sound are
           smoother and perform better.  New Advanced Linux Sound Architecture
           (ALSA) brings professional music-studio quality audio.
