2008-12-12tracing/function-graph-tracer: add a new .irqentry.text sectionFrederic Weisbecker1-0/+1
Impact: let the function-graph-tracer be aware of the irq entrypoints Add a new .irqentry.text section to store the irq entrypoints functions inside the same section. This way, the tracer will be able to signal an interrupts triggering on output by recognizing these entrypoints. Also, make this section recordable for dynamic tracing.

2008-12-01kernel-doc: handle varargs cleanlyRandy Dunlap1-3/+7
The method for listing varargs in kernel-doc notation is: * @...: these arguments are printed by the @fmt argument but scripts/kernel-doc is confused: it always lists varargs as: ... variable arguments and ignores the @...: line's description, but then prints that line after the list of function parameters as though it's not part of the function parameters. This patch makes kernel-doc print the supplied @... description if it is present; otherwise a boilerplate "variable arguments" is printed.

2008-11-26tracing: add "power-tracer": C/P state tracer to help power optimizationArjan van de Ven1-0/+108
Impact: new "power-tracer" ftrace plugin This patch adds a C/P-state ftrace plugin that will generate detailed statistics about the C/P-states that are being used, so that we can look at detailed decisions that the C/P-state code is making, rather than the too high level "average" that we have today. An example way of using this is: mount -t debugfs none /sys/kernel/debug echo cstate > /sys/kernel/debug/tracing/current_tracer echo 1 > /sys/kernel/debug/tracing/tracing_enabled sleep 1 echo 0 > /sys/kernel/debug/tracing/tracing_enabled cat /sys/kernel/debug/tracing/trace | perl scripts/trace/cstate.pl > out.svg Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-11-26ftrace: adding other non-leaving .text sectionsLiming Wang1-0/+2
Impact: widen the scope of recordmcount.pl Besides .text section, there are three .text sections that won't be freed after kernel booting. They are: .sched.text, .spinlock.text and .kprobes.text, which contain functions we can trace. But the last section ".kprobes.text" is particular, which has been marked as "notrace", we ignore it. Thus we add other two sections. Signed-off-by: Liming Wang <liming.wang@windriver.com> Acked-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-10-29Fix incompatibility with versions of Perl less than 5.6.0Jeremy Huntwork2-13/+14
Fix headers_install.pl and headers_check.pl to be compatible with versions of Perl less than 5.6.0. It has been tested with Perl 5.005_03 and 5.8.8. I realize this may not be an issue for most people, but there will still be some that hit it, I imagine. There are three basic issues: 1. Prior to 5.6.0 open() only used 2 arguments, and the versions of the scripts in 2.6.27.1 use 3. 2. 5.6.0 also introduced the ability to use uninitialized scalar variables as file handles, which the current scripts make use of. 3. Lastly, 5.6.0 also introduced the pragma 'use warnings'. We can use the -w switch and be backwards compatible.

2008-10-29kbuild: tag with git revision when git describe is missingTrent Piepho1-1/+3
setlocalversion used to use an abbreviated git commit sha1 to generate the tag. This was changed in commit d882421f4e08ddf0a94245cdbe516db260aa6f41 "kbuild: change CONFIG_LOCALVERSION_AUTO to use a git-describe-ish format" to use git describe to come up with a tag. Which is nice, but git describe sometimes can't describe the revision. Commit 56b2f0706d82535fd8d85503f2dcc0be40c8e55d ("setlocalversion: do not describe if there is nothing to describe") addressed this, but there is still no tag generated.

2008-10-26fix allmodconfig breakageAl Viro1-2/+1
If you use KCONFIG_ALLCONFIG (even with empty file) you get broken allmodconfig/allyesconfig; CONFIG_MODULES gets turned off, with obvious massive fallout. Breakage had been introduced when conf_set_all_new_symbols() got used for allmodconfig et.al. What happens is that sym_calc_value(modules_sym) done in conf_read_simple() sets SYMBOL_VALID on both modules_sym and MODULES. When we get to conf_set_all_new_symbols(), we set sym->def[S_DEF_USER] on everything, but it has no effect on sym->curr for the symbols that already have SYMBOL_VALID - these are stuck. Solution: use sym_clear_all_valid() in there. Note that it makes reevaluation of modules_sym redundant - sym_clear_all_valid() will do that itself.

2008-10-23ftrace: dynamic ftrace process only text sectionSteven Rostedt1-3/+14
