perf trace: Beautify fcntl 'cmd' arg · 80f587d5

由 Arnaldo Carvalho de Melo 提交于 9月 03, 2013

This is just for the low hanging fruit 'cmd' arg, a proper beautifier
will as well use arg->mask to ignore the third arg for some of the
cmds.

perf trace: Allow passing parms to arg formatters · 1f115cb7

由 Arnaldo Carvalho de Melo 提交于 9月 03, 2013

So that we can have generic formatters that act upon specific
parameters.

Start using them with a simple string table that assumes entries
will be indexes to a string table, like with the 'which' parm
for the set and getitimer syscalls

perf trace: Put syscall formatter parms into struct · 01533e97

由 Arnaldo Carvalho de Melo 提交于 9月 03, 2013

So that we can add more state to formatters without having to modify
all of them.

Example is to pass a table to a generic string formatter, like for
setitimer 'which' arg.

tools/perf/build: Pass through LDFLAGS to feature tests · aa4acf6c

由 Ingo Molnar 提交于 10月 07, 2013

David Ahern reported that when passing in LDFLAGS=-static then
the feature checks still succeed - causing build failures down
the line because the static libraries are missing.

Solve this by passing through LDFLAGS to the feature-check
Makefile.

tools/perf/build: Harmonize the style of the feature testcases · 20c99e82

由 Ingo Molnar 提交于 10月 07, 2013

The various testcases used different styles, which was not really
visible as long as they hid in feature-tests.mak. Now that they
are out in the open make them prettier.

( Also delete the leftover, empty feature-tests.mak file. )

tools/perf/build: Fix O=/some/dir perf.o type of targets · 1f7c645a

由 Ingo Molnar 提交于 10月 04, 2013

If someone specifies a single target, mixed with O=, the following way:

    hubble:~/tip/tools/perf> make O=/tmp/perf util/stat.o
    BUILD: Doing 'make -j8' parallel build
    gcc  -Wbad-function-cast -Wdeclaration-after-statement -Wformat-security -Wformat-y2k [...]

The build might even fail, if a target depends on other targets:

    hubble:~/tip/tools/perf> make O=/tmp/perf perf.o
    ...
    perf.c: In function ‘handle_options’:
    perf.c:155:21: error: ‘PERF_HTML_PATH’ undeclared (first use in this function)

The correct way to invoke such targets is:

    hubble:~/tip/tools/perf> make O=/tmp/perf /tmp/perf/perf.o
    BUILD: Doing 'make -j8' parallel build
    GEN /tmp/perf/common-cmds.h
    CC /tmp/perf/perf.o

But that's unnecessary typing and it's also easy to mistakenly build into the
source directory.

To fix this remove the generic suffix rules and add redirection to $(OUTPUT)
for the most popular .o targets.

tools/perf/build: Fix non-canonical directory names in O= · b102420b

由 Ingo Molnar 提交于 10月 04, 2013

This was a long-standing bug, relative pathnames like O=dir did not fully
work in the build system:

    $ make O=localdir clean

    SUBDIR Documentation
    ../../scripts/Makefile.include:3: *** O=localdir does not exist.  Stop.
    make[1]: *** [clean] Error 2
    make: *** [clean] Error 2

Fix this by canonizing the directory before passing it to Makefile.perf.

tools/perf/build: Exclude MAKEFLAGS from nested invocation · 684f434c

由 Ingo Molnar 提交于 10月 04, 2013

In case the user specifies MAKEFLAGS as an environment variable,
or uses 'make -jN' explicitly, the options can conflict and result in:

    BUILD: Doing 'make -j8' parallel build
    make[1]: warning: -jN forced in submake: disabling jobserver mode.
    GEN common-cmds.h
    make[1]: *** write jobserver: Bad file descriptor.  Stop.

Make sure we invoke the main makefile in a pristine state.

Users who want to do something non-standard can use the:

  make -f Makefile.perf

method to invoke the makefile.

This is due to GNU make having built-in rules for popular targets such
as *.o. Clear them out so that all targets as passed through to Makefile.perf.
