e.g., compiling i386 on x86_64 using:
$ make -C tools/perf ARCH=i386
fails with:
CC /tmp/pbuild/util/evsel.o
In file included from util/evsel.c:21:0:
util/perf_regs.h:5:23: fatal error: perf_regs.h: No such file or directory
compilation terminated.
Adding V=1 you see that the include argument for the arch is
'-Iarch/i386/include' is wrong. It is supposed to be -Iarch/x86/include
per the redefinition of ARCH in the Makefile.
According to the make manual,
http://www.gnu.org/software/make/manual/make.html#Override-Directive:
"If a variable has been set with a command argument (see Overriding
Variables), then ordinary assignments in the makefile are ignored. If
you want to set the variable in the makefile even though it was set
with a command argument, you can use an override directive ..."
Make it so.

To keep the KVP daemon code free of distro specific details, we invoke an

this script can be based on NM APIs.

As pevent_errno is defined using PEVENT_ERRORS which uses _PE macro
magic, the first errno is bigger than __PEVENT_ERRNO_START by 1. So we

The pevent_strerror() sets @buf to a string that describes the
(libtraceevent-specific) error condition that is passed via @errnum.
This is similar to strerror_r() and does same thing if @errnum has a
standard errno value.
To sync error string with its code, define PEVENT_ERRORS with _PE()
macro and use it as suggested by Steven.

die() and do_warning() calls. If the function returns non-zero value,
the caller can check the return code and do appropriate things.
I chose the error numbers to be negative not to clash with standard
errno, and as usual, 0 for success.

With dynamic pmu allocation there are also dynamically assigned pmu ids.
These ids are used in event->attr.type to describe the pmu to be used
for that event. The information is available in sysfs, e.g:
/sys/bus/event_source/devices/breakpoint/type: 5
/sys/bus/event_source/devices/cpu/type: 4
/sys/bus/event_source/devices/ibs_fetch/type: 6
/sys/bus/event_source/devices/ibs_op/type: 7
/sys/bus/event_source/devices/software/type: 1
/sys/bus/event_source/devices/tracepoint/type: 2
These mappings are needed to know which samples belong to which pmu. If
a pmu is added dynamically like for ibs_fetch or ibs_op the type value
may vary.
Now, when decoding samples from perf.data this information in sysfs
might be no longer available or may have changed. We need to store it in
perf.data. Using the header for this. Now the header information created
with perf report contains an additional section looking like this:
# pmu mappings: ibs_op = 7, ibs_fetch = 6, cpu = 4, breakpoint = 5, tracepoint = 2, software = 1

Name events based on the event description in the perf.data header.

# event : name = ibs_fetch/config=0/, type = 6, config = 0x0, config1 = 0x0, config2 = 0x0, excl_usr = 0, excl_kern = 0, excl_host = 0, excl_guest = 1, precise_ip = 0, id = { 57, 58, 59, 60, 61, 62, 63, 64 }
# Samples: 20K of event 'ibs_op/cnt_ctl=1/GH'

Use command line string provided by the -e option to name events. This
way we get unique events names that also support pmu event syntax
(<pmu_name>/<config>/<modifier>). No need to reconstruct the name
anymore from its attributes. We use the event_desc of the header to
store the name in the perf.data header. Thus it is also available for
perf report.
Implemented by putting the parser in different states to parse events or
configs.
And since event names are now generated from the command line
specification. Update event names in test cases accordingly.

Changeset 0f6a3015:
"perf tools: Support user regs and stack in sample parsing"
uses hweight_long in evsel.c, so we need to drag util/hweight.c
to the python binding.
Ditto for ee8dd3c:
"perf tools: Change strlist to use the new rblist"
where we need to add util/rblist.c.
Now twatch.py works again:

When we use a separate output directory, we add util/ to the include
path for the generated C files. However, this is currently added to the
end of the path, behind /usr/include/slang and /usr/include/gtk-2.0 if
use of the respective libraries is enabled. Thus the '#include
"../perf.h"' in util/parse-events.l can actually include
/usr/include/perf.h if it exists.
Move '-Iutil/' ahead of all the other preprocessor options.

Use same type for ids everywhere.
In case of writing to perf.data the size is u32. In pipe mode it is
limited to header.size (less than u16). Adding a size check here.
Size overflow due to casting shouldn't actually happen in practice, but
during development this may cause type missmatch warninngs/errors,
unifying types avoids this.
