tools: Copy rbtree_augmented.h from the kernel

2015-07-06T01:59:05+00:00

To complete the transitioning to not to share the same files with the
kernel, also moving it from tools/perf/include/linux/ to
tools/include/linux to make the whoke rbtree kit to other tools/ living
codebases.

tools: Move rbtree.h from tools/perf/

2015-07-06T01:54:01+00:00

The previous step, copying the contents minus the rcupdate.h parts, was
done as a minimal fix, now do the move from tools/perf/.

perf tools: Copy rbtree.h from the kernel

2015-07-05T18:05:08+00:00

We were using the include/linux/rbtree.h directly from the kernel,
which broke the build as soon as it started using rcupdate.h, to
avoid dragging the rcu header files into tools/, for which there is
no use so far, grab a copy of rbtree.h.

This is the minimal fix, later patches will copy as well lib/rbtree.c
and move rbtree.h into tools/include/, etc.

tools: Move tools/perf/util/include/linux/{list.h,poison.h} to tools/include

2015-06-02T22:07:29+00:00

This patch moves list.h from tools/perf/util/include/linux/list.h to
tools/include/linux/list.h to enable other libraries use macros in it,
like libbpf which will be introduced by further patches. Since list.h
depend on poison.h, poison.h is also moved.

Both file use relative path, so one '..' is removed for each header to
make them suit for new directory.

MANIFEST is also updated for 'make perf-*-src-pkg'.

perf tools: Move linux/kernel.h to tools/include

2015-06-02T18:27:04+00:00

This patch moves kernel.h from tools/perf/util/include/linux/kernel.h
to tools/include/linux/kernel.h to enable other libraries use macros in
it, like libbpf which will be introduced by further patches.

MANIFEST is also updated for 'make perf-*-src-pkg'.

perf tools: Import rb_erase_init from block/ in the kernel sources

2015-05-27T15:21:44+00:00

I was assuming rb_erase() was setting things up like list_del_init, but
the fact that thread__delete() was being sucessfull is because the last
thing before deleting is to remove the thread from the
machine->dead_threads list, using list_del_init(), that has the same
effect as using rb_erase_init()...

Introduce this function so that we can use it when removing objects from
rb_trees.

Then we will be able to BUG_ON(still on a list) in destructors.

tools: Remove bitops/hweight usage of bits in tools/perf

2015-01-16T20:49:29+00:00

We need to use lib/hweight.c for that, just like we do for lib/rbtree.c,
so tools need to link hweight.o. For now do it directly, but we need to
have a tools/lib/lk.a or .so that collects these goodies...
