Hi Ingo,
Mostly a 'perf annotate' refactoring to allow reusing the TUI formatting routines in a --stdio2 mode for 'perf annotate' that at some point should replace --stdio, leaving that old code deprecated for a while, then ditching it.
That will take a while yet because there is some stuff in the --stdio code that needs to be done in the annotation UI agnostic core to then get used in --tui and --stdio2.
There is also some improvements for issues Linus reported in the TUI annotation code for ASM functions.
Please consider pulling,
- Arnaldo

perf annotate: Use absolute addresses to calculate jump target offsets (2018-03-23 16:46:53 -0300)
---------------------------------------------------------------- perf/core improvements and fixes:
- Move non-TUI specific annotation routines out of the TUI browser so that it can be used in other UIs, and to demonstrate that introduce a 'perf annotate --stdio2' option that will apply those formatting routines to provide a non-interactive annotation mode (Arnaldo Carvalho de Melo)
- Add 'P' hotkey to the annotation TUI, so dump the current annotated symbol to a file, easing report thru e-mail, by getting rid of the spaces + right hand side scrollbar chars (Arnaldo Carvalho de Melo)
- Support --ignore-vmlinux to 'perf report' and 'perf annotate', that was already present in 'perf top', to use /proc/{kcore,kallsyms}, allowing to see what is in fact running (patched stuff, alternatives, ftrace, etc), not the initial state of the kernel (vmlinux) (Arnaldo Carvalho de Melo)
- Support 'jump' instructions to a different function, treating them as 'call' instructions (Arnaldo Carvalho de Melo)
- Fix some jump artifacts when using vmlinux + ASM functions, where the ELF symtab for instance, for entry_SYSCALL_64 includes that and what comes after the 'syscall_return_via_sysret' label, but the objdump -dS prints the jump targets + offsets using the syscall_return_via_sysret address, which was confusing 'perf annotate'. See the cset comments for further info (Arnaldo Carvalho de Melo)
- Report error from dwfl_attach_state() in the unwind code (Martin Vuille)
- Reference Py_None before returning it in the python extension (Petr Machata)

Test results:
The first ones are container (docker) based builds of tools/perf with and without libelf support. Where clang is available, it is also used to build perf with/without libelf.
The objtool and samples/bpf/ builds are disabled now that I'm switching from using the sources in a local volume to fetching them from a http server to build it inside the container, to make it easier to build in a container cluster. Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those may not have all the features built, due to lack of multi-arch devel packages, available and being used so far on just a few, like debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands with a variety of command line event specifications to then intercept the sys_perf_event syscall to check that the perf_event_attr fields are set up as expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/ with a variety of feature sets, exercising the build with an incomplete set of features as well as with a complete one. It is planned to have it run on each of the containers mentioned above, using some container orchestration infrastructure. Get in contact if interested in helping having this in place.
