Kernel 2.4 based

There are currently three recommended kernel 2.4 "streams" available on developerWorks.

1. "June 2003 stream"
   The "June 2003 stream" has the most functionality of all kernel 2.4 streams. It introduces support for several new hardware features of the IBM z990 systems and consists of:
   • kernel 2.4.21 (with integrated "Order-2 allocation relief" patch and separate "On-demand timer" patch)
   • OCO modules: none
     • tape_3590 OCO module replaced by open source 3590 tape device driver discipline in May 2006.
     • lcs, qdio, qeth, and z90crypt provided as part of kernel-patch.
     • No special OCO modules required for "On-demand timer" and "Order-2 allocation relief".
   • tool-chain: binutils 2.14.90.0.4, gcc 3.3, glibc 2.3.2
   • utilities: modutils 2.4.7, s390-tools 1.2.4
   • debug tools: gdb 5.3, strace 4.4
2. "May 2002 stream" (superseded by "June 2003 stream")
   The "May 2002 stream" introduced support for new hardware features of the IBM z900 and z800 systems and consists of:
   • kernel 2.4.19 (with integrated "Order-2 allocation relief" patch and separate "On-demand timer" patch)
   • OCO modules: qeth, tape_3590_mod
     • z90crypt, lcs, and qdio provided as part of kernel-patch.
     • No special OCO modules required for "On-demand timer" and "Order-2 allocation relief".
   • tool-chain: binutils 2.12.90.0.15, gcc 3.2, glibc 2.2.5
   • utilities: modutils 2.4.7, s390-tools 1.1.7
   • debug tools: gdb 5.3 or 5.2.1, strace 4.4
3. "August 2001 stream"
   The "August 2001 stream" consists of:
   • kernel 2.4.7 or kernel 2.4.17 (both with separate "On-demand timer" and "Order-2 allocation relief" patches)
   • OCO modules: qdio, qeth, tape_3590_mod
     • z90crypt, lcs provided as part of kernel-patch.
     • Special OCO modules required for "On-demand timer".
     • No special OCO modules required for "Order-2 allocation relief".
   • tool-chain: binutils 2.11.90.0.27, gcc 2.95.3, glibc 2.2.4
   • utilities: modutils 2.4.7, s390-tools 1.0.6
   • debug tools: gdb 5.0, strace 4.2
