To simplify the passing of arguments, the --stdio2 code will have to set
all the fields with operations printing to stdout.

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:

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.

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.

Here is a patch series to move the tsl2x7x driver out of staging and
into mainline. Driver was tested using various TSL2X7X devices on a
Raspberry Pi 2.
Datasheet for the TSl2772:

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
The hardware supports 16-bit ALS and proximity readings, however the
datasheet recommends using the I2C auto increment protocol so that the
correct high and low bytes are read even if the integration cycle ends
between reading the lower and upper registers. More information about
this protocol can
The events IIO_EV_INFO_VALUE and IIO_EV_INFO_ENABLE currently have a

separate distinction so this patch changes these to use the
either direction. Directory listing of event sysfs attributes for a

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:

Things like this in _cpp_lex_token (gcc's cc1 program):

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

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.

We pass some more callbacks and all of annotate_browser__write() seems
to be free of TUI code (except for some arrow constants, will fix).
