perf probe: Support probing on offline cross-arch binary

2016-09-01T15:41:09+00:00

Support probing on offline cross-architecture binary by adding getting
the target machine arch from ELF and choose correct register string for
the machine.

Here is an example:
  -----
  $ perf probe --vmlinux=./vmlinux-arm --definition 'do_sys_open $params'
  p:probe/do_sys_open do_sys_open+0 dfd=%r5:s32 filename=%r1:u32 flags=%r6:s32 mode=%r3:u16
  -----

Here, we can get probe/do_sys_open from above and append it to to the target
machine's tracing/kprobe_events file in the tracefs mountput, usually
/sys/kernel/debug/tracing/kprobe_events (or /sys/kernel/tracing/kprobe_events).

perf tools: Remove tools/perf/util/include/linux/const.h

2016-07-18T20:53:22+00:00

Not used anymore, remove one more file referencing kernel sources, i.e.
outside of tools/

perf tools: Remove tools/perf/util/include/asm/byteorder.h

2016-07-18T20:52:42+00:00

Not used anymore. This also stops include linux/swab.h directly
from the kernel sources, remove that reference from the MANIFEST.

perf bench: Copy kernel files needed to build mem{cpy,set} x86_64 benchmarks

2016-07-12T18:20:32+00:00

We can't access kernel files directly from tools/, so copy the required
bits, and make sure that we detect when the original files, in the
kernel, gets modified.

perf tools: Move syscall number fallbacks from perf-sys.h to tools/arch/x86/include/asm/

2016-07-12T18:19:54+00:00

And remove the empty tools/arch/x86/include/asm/unistd_{32,64}.h files
introduced by eae7a755ee81 ("perf tools, x86: Build perf on older
user-space as well").

This way we get closer to mirroring the kernel for cases where __NR_
can't be found for some include path/_GNU_SOURCE/whatever scenario.

tools lib: Move bitmap.[ch] from tools/perf/ to tools/{lib,include}/

2016-01-08T15:35:46+00:00

So that lib/find_bit.c doesn't requires anything inside tools/perf/

Need to move the bitmap.[ch] things from tools/perf/ to tools/lib, will
be done in the next patches.

tools: Adopt memdup() from tools/perf, moving it to tools/lib/string.c

2015-11-18T20:51:02+00:00

That will contain more string functions with counterparts, sometimes
verbatim copies, in the kernel.

perf tools: regs_query_register_offset() infrastructure

2015-09-15T12:48:33+00:00

regs_query_register_offset() is a helper function which converts
register name like "%rax" to offset of a register in 'struct pt_regs',
which is required by BPF prologue generator.

PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET indicates an architecture
supports converting name of a register to its offset in 'struct
pt_regs'.

HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET is introduced as the corresponding
CFLAGS of PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET.

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.
