litmus2008.git/kernel/Kconfig.instrumentation, branch master [ARCHIVE] Old LITMUS^RT 2008 version (for reference). Tiny clean-up of OPROFILE/KPROBES configuration 2007-12-06T17:41:12+00:00 Linus Torvalds torvalds@woody.linux-foundation.org 2007-12-06T17:41:12+00:00 3743d33edf4e49376384822c57c4ee5cdf2d32f8 Make the Kconfig.instrumentation file a bit easier on the eyes, and use the new ARCH_SUPPORTS_OPROFILE for x86[-64].

Fix oprofile configuration breakage 2007-12-06T17:37:03+00:00 Ralf Baechle ralf@linux-mips.org 2007-12-06T16:53:19+00:00 00a5825332769706eb2e276c101dd20269a53992 The cleanup 09cadedbdc01f1a4bea1f427d4fb4642eaa19da9 broke the oprofile configuration for MIPS by allowing oprofile support to be built for kernel models where oprofile doesn't have a chance in hell to work. Just a dependecy list on a number of architectures is - surprise - broken and should as per past discussions probably in most considered to be broken in most cases. So I introduce a dependency for the oprofile configuration on ARCH_SUPPORTS_OPROFILE. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

uml: add !UML dependencies 2007-12-03T16:13:17+00:00 Al Viro viro@zeniv.linux.org.uk 2007-12-01T20:16:29+00:00 b00296fb781acfafa93687000cdef72b8922bb40 The previous commit ("uml: keep UML Kconfig in sync with x86") is not enough, unfortunately.

Linux Kernel Markers 2007-10-19T18:53:54+00:00 Mathieu Desnoyers mathieu.desnoyers@polymtl.ca 2007-10-19T06:41:06+00:00 8256e47cdc8923e9959eb1d7f95d80da538add80 The marker activation functions sits in kernel/marker.c. A hash table is used to keep track of the registered probes and armed markers, so the markers within a newly loaded module that should be active can be activated at module load time. marker_query has been removed. marker_get_first, marker_get_next and marker_release should be used as iterators on the markers.

Combine instrumentation menus in kernel/Kconfig.instrumentation 2007-10-19T18:53:54+00:00 Mathieu Desnoyers mathieu.desnoyers@polymtl.ca 2007-10-19T06:41:05+00:00 09cadedbdc01f1a4bea1f427d4fb4642eaa19da9 Quoting Randy: "It seems sad that this patch sources Kconfig.marker, a 7-line file, 20-something times. Yes, you (we) don't want to put those 7 lines into 20-something different files, so sourcing is the right thing.
