tweewide: Fix most Shebang lines

2021-06-03T06:23:27+00:00

commit c25ce589dca10d64dde139ae093abc258a32869c upstream.

Change every shebang which does not need an argument to use /usr/bin/env.
This is needed as not every distro has everything under /usr/bin,
sometimes not even bash.

perf tools: Fix python extension build

2016-02-29T14:18:25+00:00

The util/python-ext-sources file contains source files required to build
the python extension relative to $(srctree)/tools/perf,

Such a file path $(FILE).c is handed over to the python extension build
system, which builds the final object in the
$(PYTHON_EXTBUILD)/tmp/$(FILE).o path.

After the build is done all files from $(PYTHON_EXTBUILD)lib/ are
carried as the result binaries.

Above system fails when we add source file relative to ../lib, which we
do for:

  ../lib/bitmap.c
  ../lib/find_bit.c
  ../lib/hweight.c
  ../lib/rbtree.c

All above objects will be built like:

  $(PYTHON_EXTBUILD)/tmp/../lib/bitmap.c
  $(PYTHON_EXTBUILD)/tmp/../lib/find_bit.c
  $(PYTHON_EXTBUILD)/tmp/../lib/hweight.c
  $(PYTHON_EXTBUILD)/tmp/../lib/rbtree.c

which accidentally happens to be final library path:

  $(PYTHON_EXTBUILD)/lib/

Changing setup.py to pass full paths of source files to Extension build
class and thus keep all built objects under $(PYTHON_EXTBUILD)tmp
directory.

tools lib api: Rename libapikfs.a to libapi.a

2015-02-12T20:55:18+00:00

Renaming libapikfs.a to libapi.a, because it's not just 'fs' specific
library now.

tools/: Convert to new topic libraries

2013-12-16T19:03:27+00:00

Move debugfs.* to api/fs/. We have a common tools/lib/api/ place where
the Makefile lives and then we place the headers in subdirs.

For example, all the fs-related stuff goes to tools/lib/api/fs/ from
which we get libapikfs.a (acme got almost the naming he wanted :-)) and
we link it into the tools which need it - in this case perf and
tools/vm/page-types.

acme:

"Looking at the implementation, I think some tools can even link
directly to the .o files, avoiding the .a file altogether.

But that is just an optimization/finer granularity tools/lib/
cherrypicking that toolers can make use of."

Fixup documentation cleaning target while at it.

perf tools: Introduce tools/lib/lk library

2013-03-15T16:06:00+00:00

This introduces the tools/lib/lk library, that will gradually have the
routines that now are used in tools/perf/ and other tools and that can
be shared.

Start by carving out debugfs routines for general use.

perf python: Properly link with libtraceevent

2012-10-20T00:43:08+00:00

Namhyung Kim reported that the build fails with:

  GEN python/perf.so
  gcc: error: python_ext_build/tmp//../../libtraceevent.a: No such file or directory
  error: command 'gcc' failed with exit status 1
  cp: cannot stat `python_ext_build/lib/perf.so': No such file or directory
  make: *** [python/perf.so] Error 1

We need to propagate the TE_PATH variable to the setup.py file.

perf tools: Fix build dependency of perf python extension

2012-02-13T20:01:25+00:00

The perf python extention (perf.so) file lacks its dependencies in the
Makefile so that it cannot be refreshed if one of source files it depends
is changed. Fix it by putting them in a separate file and processing it in
both of Makefile and setup.py.
