Linux Forums
The Linux discussion forums are the place for developers, administrators, and users to ask questions, get answers, and share knowledge about the Linux operating system and related technologies. Whatever your hardware -- x86, Power-based, or mainframe -- the developerWorks Linux community welcomes you. Our discussion forums
work best when people follow these community guidelines.

Advance Toolchain for Linux on POWER
The Advance Toolchain is a collection of free-software application development products specifically tailored to make early use of IBM hardware features. It includes GCC (GNU Compiler Collection), GLIBC (GNU C Libraries), GNU binary utilities, GDB ( GNU debugger), and the performance analysis tools (QProfile and Valgrind) in a self contained Toochain. The Advance Toolchain duplicates the function of packages already delivered by Linux distributors but provides additional features for the POWER6 and now POWER7 family of processors as indicated in the Advance Toolchain Release Notes 'Features' section.
The Advance Toolchain is built by and available from the University of Illinois at ftp://linuxpatch.ncsa.uiuc.edu/toolchain.

Chiphopper Tool Use
The Chiphopper offering has expanded access to its tools to include customers and non-participating ISVs. These tools can help maintain single source for C and C++ code on mutiple Linux platforms. They can be useful to run prior to doing a port to a new IBM system running Linux, or during a consolidation exercise onto a larger Linux system.The tools come from two sources -- the Linux Foundation as part of Linux Standard Base (LSB) certification for applications, and also from the IBM Chiphopper team. The LSB tools check for use of standard APIs, and the Chiphopper tool checks for coding to differences in hardware platforms that could cause portability problems. This forum is designed to help people using these tools exchange information about the tools and interpreting their output to achieve more efficient Linux portability. The external web site is http://www-128.ibm.com/developerworks/linux/chiphopper/

Energy Management for System x Blueprint Forum
Forum for discussions of and reporting issues related to the available IBM Energy Management Blueprints located on IBM's Information Center for Linux.
- The IBM Blueprint for monitoring and controlling power consumption on Linux describes how to monitor and control power use on System X servers that have the relevant hardware features--specifically, systems that support either Intel's Enhanced Speed Step (EIST) or AMD's PowerNow, and have power meter hardware installed.
- The CPUFreq Blueprint describes how to use the Linux CPUFreq subsystem on RHEL5.3 to exploit the processor performance state (P-state) feature that is commonly available to newer processors. This feature can be configured to statically alter the processor operating frequency or dynamically scale the frequency to the current processor usage, so that less power is consumed without performance loss.
