All releases of OProfile
Release Notes: A new "operf" program is now available which allows non-root users to profile single processes. "operf" can also be used for system-wide profiling, but root authority is required. This capability requires a kernel version of 2.6.31 or greater. This release supports the processors Tilera tile64, Tilera tilepro, Tilera tile-gx, IBM System z10, IBM System z196, Intel Ivy Bridge, ARMv7 Cortex-A5, ARMv7 Cortex-A15, and ARMv7 Cortex-A7.
Release Notes: This release supports the processors MIPS Loongson2, Intel Nehalem, ARM Cortex-A9, MIPS 74K, MIPS 1004K, AMD family12h, AMD family14h, AMD family15h, Intel Westmere, ARMv7 Scorpion, ARMv7 ScorpionMP, and Intel Sandy Bridge, allows additional flags in unitmasks, and enables Qt4 GUI support.
Release Notes: This is strictly a bugfix release. Its main purpose is to fix three regression bugs that occurred in 0.9.5: bug #2845063 (opcontrol could not start daemon in timer mode); improper handling of separate debuginfo files; and XML callgraph output had no symbol-level sample counts. Several other minor bugfixes and updates were made.
Release Notes: This release includes support for several new processor models: ARMv7, AMD family11h, IBM POWER7, Intel Atom, Intel Core i7, and Xeon 55xx (based on Nehalem core). Many other features and bugfixes are included as well. This release also includes a framework for extending the sample data files. Support for AMD Instruction Based Sampling (IBS) has been added, using the new extended feature framework. Additionally, this release supports architected events for for Intel ("arch perfmon") and IBM POWER ("compatibility events").
Release Notes: This release has many new features and fixes. The biggest change with this release is the addition of support for profiling JITed code. Java agents that support Java 1.4 (JVMPI) and later (JVMTI) are included with OProfile.
Release Notes: Thie release contains new processor support for Cell BE, IBM POWER6, AMD Family 10, PA Semi PA6T, ARM11, and ARM MPCore. Other new features include a '--session-dir' option, an '--XML' option for opreport, and enhancement to oparchive for saving debuginfo files.
Release Notes: Additional and revised support for a number of processor implementations (PPC64 Power5+, PPC/e500, Intel Core Duo , Intel Core 2, MIPS 5K, MIPS 20K, MIPS25K, MIPS34K, and AMD64). Also support for use in a Xen environment.
Release Notes: MIPS 24k support was added. Important fixes were made for ARM users, as well as some other minor fixes.
Release Notes: This release adds a differential profile feature, reworked call-graph output, and many other improvements and fixes.
Release Notes: Support for PPC64 and MIPS performance counters has been added. This requires a recent 2.6 kernel. Some critical bugfixes and other improvements have been made.
