Hi all,
When I read the code and document of perf tool as a newbie,
I feel confused in some places. Then I made some patches here to make
them more clear.
Please help to review them.
Note: The last 3 commits are all about perf-kvm.txt. I splite them
to make the logic more clear.
As option --host and --guest request no input for it, there should
not be a '=' after them in Document. And --output request a filename
as the input, so there should be a '=' after it. This patch remove
the wrong '=' after --guest and --host, and add a '=' after --output
in perf-kvm.txt.
As the buildid is read from /sys/kernel/notes, then if we use perf kvm
buildid-list
with a perf data file captured by perf kvm record with --guestkallsyms and
--guestmodules,
there is no result in output. This patch add a explanation about it and add a
limit
of using perf kvm buildid-list.
In machine__get_kernel_start_addr, the code, which is
using machine-root_dir to build filename, works for both
host and guests initialized from guestmount. So this patch
remove the branch for machine__is_host.

This patch introduces new branch filter PERF_SAMPLE_BRANCH_COND which
will extend the existing perf ABI. Other architectures can provide
this functionality with either HW filtering support (if present) or
with SW filtering of
This patch adds enumeration for all available SW branch filters
in powerpc book3s code and also streamlines the look for the
SW branch filter entries while trying to figure out which all
branch filters can be supported in SW.

This patchset is the re-spin of the original branch stack
sampling
patchset which introduced new PERF_SAMPLE_BRANCH_COND branch filter. This
patchset
also enables SW based branch filtering support for book3s powerpc platforms
which
have PMU HW backed branch stack sampling
This patch enables SW based post processing of BHRB captured branches
to be able to meet more user defined branch filtration criteria in perf
branch stack sampling framework. These changes increase the number of
branch filters and their valid combinations on any powerpc64 server
platform with BHRB

Powerpc kernel now supports SW based branch filters for book3s systems with some
specifc requirements while dealing with HW supported branch filters in order to
achieve overall OR semantics prevailing in perf branch stack sampling framework.
This patch adapts the BHRB branch filter configuration
This patch simply changes the name of the variable from bhrb_filter to
bhrb_hw_filter in order to add one more variable which will track SW
filters in generic powerpc book3s code which will be implemented in the
subsequent patch.

Generic powerpc branch instruction analysis support added in the code
patching library which will help the subsequent patch on SW based
filtering of branch records in perf. This patch also converts and
exports some of the existing local static functions through the header
file to be used else
Enables conditional branch filter support for POWER8
utilizing MMCRA register based filter and also invalidates
any BHRB branch filter combination.

Hi,
This is sixth version of patchset adding drivers for MAXIM 14577 chip.
Some parts (MFD, extcon) were already merged by maintainers so I removed them
from the patchset.
This version of patchset depends on the max14577 MFD core driver:
- mfd: max14577: Add max14577 MFD driver core
Merged
MAX14577 chip is a multi-function device which includes MUIC, charger
and voltage regulator. The driver is located in drivers/mfd.
This patch supports battery charging control of MAX14577 chip and
provides power supply class information to userspace.
