Date: Thu, 24 Apr 2008 11:03:24 -0400 From: Mathieu Desnoyers <mathieu.desnoyers@...ymtl.ca> To: akpm@...ux-foundation.org, Ingo Molnar <mingo@...e.hu>, linux-kernel@...r.kernel.org Subject: [patch 00/37] Linux Kernel Markers instrumentation for sched-devel.git Hi Ingo, Here is a rather large patchset applying kernel instrumentation to sched-devel.git. It includes, mainly : - x86 NMI-safe traps. - Optimized Markers, using Immediate Values, with nops/jump patching optimization. - ftrace sched and wakeup tracer port to the markers. - The archtecture independent instrumentation found in LTTng. Please see the individual patches for more details. A diffstat is appended at the bottom of this email. They apply in the following order on to of current sched-devel.git : stringify-support-commas.patch # x86_64-page-fault-nmi-safe.patch change-alpha-active-count-bit.patch change-avr32-active-count-bit.patch x86-nmi-safe-int3-and-page-fault.patch # kprobes-use-mutex-for-insn-pages.patch kprobes-dont-use-kprobes-mutex-in-arch-code.patch kprobes-declare-kprobes-mutex-static.patch fix-sched-devel-text-poke.patch text-edit-lock-architecture-independent-code.patch text-edit-lock-kprobes-architecture-independent-support.patch # # Immediate Values (basic) add-all-cpus-option-to-stop-machine-run.patch immediate-values-architecture-independent-code.patch immediate-values-kconfig-menu-in-embedded.patch immediate-values-x86-optimization.patch add-text-poke-and-sync-core-to-powerpc.patch immediate-values-powerpc-optimization.patch immediate-values-documentation.patch immediate-values-support-init.patch # Immediate Values (NMI-safe) immediate-values-move-kprobes-x86-restore-interrupt-to-kdebug-h.patch add-discard-section-to-x86.patch immediate-values-x86-optimization-nmi-mce-support.patch immediate-values-powerpc-optimization-nmi-mce-support.patch immediate-values-use-arch-nmi-mce-support.patch # Immediate Values (jump patching) immediate-values-jump.patch # scheduler-profiling-use-immediate-values.patch # make-marker_debug-static.patch # in -mm markers-remove-extra-format-argument.patch markers-define-non-optimized-marker.patch linux-kernel-markers-immediate-values.patch markers-use-imv-jump.patch # port-ftrace-to-markers.patch # # Instrumentation, architecture independent lttng-instrumentation-fs.patch lttng-instrumentation-ipc.patch lttng-instrumentation-kernel.patch lttng-instrumentation-mm.patch lttng-instrumentation-net.patch The overall diffstat : a/kernel/marker.c | 2 arch/x86/kernel/traps_32.c | 3 include/asm-generic/vmlinux.lds.h | 8 include/asm-powerpc/immediate.h | 4 include/asm-x86/immediate.h | 54 -
