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.

In verbose level 2, errors returned by libdw are reported in most cases,
but not when calling dwfl_attach_state.
Since elfutils v 0.160 (2014), dwfl_attach_state sets the error code to
report failure cause. On failure, log the reported error.

This will be useful when making parts of the TUI browser generic enough
to be used for a new stdio mode, available even when the TUI is not
built in, for explicit user decision or when the necessary library devel
files, for the slang library currently, are not available in the build
system.

From: Arnaldo Carvalho de Melo <acme@redhat.com>
This is to pave the way to have more functions shared between TUI, stdio
and the upcoming stdio2 formatting, that will use the __scnprintf
functions used by --tui in a --stdio fashion.
This partially addresses the comments added in cset 30e863bb6f70 ("perf
annotate: Compute IPC and basic block cycles"):
/*
* This should probably be in util/annotate.c to share with the tty
* annotate, but right now we need the per byte offsets arrays,
* which are only here.
*/
The following patches will address the rest.

This is needed to reduce the differences between the TUI mode and the
other annotation UIs, next csets will move that code to the UI-neutral
annotation library. Leaving it in place for now to ease review.

Out of the TUI code, as it has nothing specific to that UI and should be
used in the other output modes as well.

For the TUI, that is interactive, its interesting to have a
configuration that one can go on changing and then when moving from one
symbol annotation to another symbol, the options set while browsing the
first symbol to be kept.
But since we're trying to make this code reusable by a --stdio
formatter, we better have a pointer in struct annotation and in the TUI
case set it to the global, but use something else for other cases, such
as --stdio2.

This is not useful only for the TUI, we'll want to somehow mark the
--stdio2 lines with the most jump sources too.
And moving this will allow us to change some function signatures from
annotate_browser to ui_browser, reducing boilerplate.

to provide symbol statistics, so move it from the TUI and change the
mark_jump_targets() method to struct annotation.

That does all the extended boilerplate the TUI browser did, leaving the

Now the upcoming --stdio2 output mode should just use this one to set
things up.

This is already present in 'perf top', albeit undocumented (will fix),
and is useful to use /proc/kcore instead of vmlinux and then get what is
really in place, not what the kernel starts with, before alternatives,
ftrace .text patching, etc, see the differences:

This should be further streamlined by doing both annotations and
allowing the TUI to toggle initial/current, and show the patched
instructions in a slightly different color.

We've had this in 'perf top' for quite a while, useful if one wishes
to force using /proc/kcore to do annotation using the patched kernel
instead of the ELF image it started from, aka vmlinux.

Just like we have in the histograms browser used as the main screen for
'perf top --tui' and 'perf report --tui', to print the current
annotation to a file with a named composed by the symbol name and the
".annotation" suffix.
Here is one example of pressing 'A' on 'perf top' to live annotate a
kernel function and then press 'P' to dump that annotation, the
resulting file:
# cat _raw_spin_lock_irqsave.annotation
_raw_spin_lock_irqsave() /proc/kcore

Since we already set notes->start to map__rip_2objdump(map, sym->start)
in symbol__annotate2(), no need to calculate that address again in
symbol__calc_lines(), just use notes->start.

We need that to figure out if jumps have targets in a different
function.
E.g. _cpp_lex_token(), in /usr/libexec/gcc/x86_64-redhat-linux/5.3.1/cc1
has a line like this:

From: Arnaldo Carvalho de Melo <acme@redhat.com>
Things like this in _cpp_lex_token (gcc's cc1 program):
cpp_named_operator2name@@Base+0xa72
Point to a place that is after the cpp_named_operator2name boundaries,
i.e. in the ELF symbol table for cc1 cpp_named_operator2name is marked
as being 32-bytes long, but it in fact is much larger than that, so we
seem to need a symbols__find() routine that looks for >= current->start
and < next_symbol->start, possibly just for C++ objects?
For now lets just make some progress by marking jumps to outside the
current function as call like.
Actual navigation will come next, with further understanding of how the
symbol searching and disassembly should be done.

Python None objects are handled just like all the other objects with
respect to their reference counting. Before returning Py_None, its
reference count thus needs to be bumped.

Because they all really check if we can access data structures/visual
constructs where a "jump" instruction targets code in the same function,
i.e. things like:
__pthread_mutex_lock /usr/lib64/libpthread-2.26.so
1.95 │ mov __pthread_force_elision,%ecx
│ ┌──test %ecx,%ecx
0.07 │ ├──je 60
│ │ test $0x300,%esi
│ │↓ jne 60
│ │ or $0x100,%esi
│ │ mov %esi,0x10(%rdi)
│ 42:│ mov %esi,%edx
│ │ lea 0x16(%r8),%rsi
│ │ mov %r8,%rdi
│ │ and $0x80,%edx
│ │ add $0x8,%rsp
│ │→ jmpq __lll_lock_elision
│ │ nop
0.29 │ 60:└─→and $0x80,%esi
0.07 │ mov $0x1,%edi
0.29 │ xor %eax,%eax
2.53 │ lock cmpxchg %edi,(%r8)
And not things like that "jmpq __lll_lock_elision", that instead should behave
like a "call" instruction and "jump" to the disassembly of "___lll_lock_elision".

It'll behave just like a "call" instruction, i.e. press enter or right
arrow over one such line and the browser will navigate to the annotated
disassembly of that function, which when exited, via left arrow or esc,
will come back to the calling function.
Now to support jump to an offset on a different function...

That strchr() in jump__scnprintf() needs to be nuked somehow, as it,
IIRC is already done in jump__parse() and if needed at scnprintf() time,
should be stashed in the struct filled in parse() time.
For now jus defer it to just before where it is used.

These types of jumps were confusing the annotate browser:
entry_SYSCALL_64 /lib/modules/4.16.0-rc5-00086-gdf09348f78dc/build/vmlinux
entry_SYSCALL_64 /lib/modules/4.16.0-rc5-00086-gdf09348f78dc/build/vmlinux
Percent│ffffffff81a00020: swapgs
<SNIP>
│ffffffff81a00128: ↓ jae ffffffff81a00139 <syscall_return_via_sysret+0x53>
<SNIP>
│ffffffff81a00155: → jmpq *0x825d2d(%rip) # ffffffff82225e88 <pv_cpu_ops+0xe8>
I.e. the syscall_return_via_sysret function is actually "inside" the
entry_SYSCALL_64 function, and the offsets in jumps like these (+0x53)
are relative to syscall_return_via_sysret, not to syscall_return_via_sysret.
Or this may be some artifact in how the assembler marks the start and
end of a function and how this ends up in the ELF symtab for vmlinux,
i.e. syscall_return_via_sysret() isn't "inside" entry_SYSCALL_64, but
just right after it.
>From readelf -sw vmlinux:
80267: ffffffff81a00020 315 NOTYPE GLOBAL DEFAULT 1 entry_SYSCALL_64
316: ffffffff81a000e6 0 NOTYPE LOCAL DEFAULT 1 syscall_return_via_sysret
0xffffffff81a00020 + 315 > 0xffffffff81a000e6
So instead of looking for offsets after that last '+' sign, calculate
offsets for jump target addresses that are inside the function being
disassembled from the absolute address, 0xffffffff81a00139 in this case,
subtracting from it the objdump address for the start of the function
being disassembled, entry_SYSCALL_64() in this case.
So, before this patch:
entry_SYSCALL_64 /lib/modules/4.16.0-rc5-00086-gdf09348f78dc/build/vmlinux

With those at least navigating to the right destination, an improvement
for these cases seems to be to be to somehow mark those inner functions,
which in this case could be:
entry_SYSCALL_64 /lib/modules/4.16.0-rc5-00086-gdf09348f78dc/build/vmlinux

This all gets much better viewed if one uses 'perf report --ignore-vmlinux'
forcing the usage of /proc/kcore + /proc/kallsyms, when the above
actually gets down to:
# perf report --ignore-vmlinux
## do '/64', will show the function names containing '64',
## navigate to /entry_SYSCALL_64_after_hwframe.annotation,
## press 'A' to annotate, then 'P' to print that annotation
## to a file
## From another xterm (or see on screen, this 'P' thing is for
## getting rid of those right side scroll bars/spaces):
# cat /entry_SYSCALL_64_after_hwframe.annotation
entry_SYSCALL_64_after_hwframe() /proc/kcore

0.65 → jne swapgs_restore_regs_and_return_to_usermode
I.e. using kallsyms makes the function start/end be done differently
than using what is in the vmlinux ELF symtab and actually the hits
goes to entry_SYSCALL_64_after_hwframe, which is a GLOBAL() after the
start of entry_SYSCALL_64:
ENTRY(entry_SYSCALL_64)
UNWIND_HINT_EMPTY
<SNIP>
pushq $__USER_CS /* pt_regs->cs */
pushq %rcx /* pt_regs->ip */
GLOBAL(entry_SYSCALL_64_after_hwframe)
pushq %rax /* pt_regs->orig_ax */
PUSH_AND_CLEAR_REGS rax=$-ENOSYS
And it goes and ends at:
cmpq $__USER_DS, SS(%rsp) /* SS must match SYSRET */
jne swapgs_restore_regs_and_return_to_usermode
/*
* We win! This label is here just for ease of understanding
* perf profiles. Nothing jumps here.
*/
syscall_return_via_sysret:
/* rcx and r11 are already restored (see code above) */
UNWIND_HINT_EMPTY
POP_REGS pop_rdi=0 skip_r11rcx=1
So perhaps some people should really just play with '--ignore-vmlinux'
to force /proc/kcore + kallsyms.
One idea is to do both, i.e. have a vmlinux annotation and a
kcore+kallsyms one, when possible, and even show the patched location,
etc.
