The struct callchain_node size is 120 bytes, that are never used when
there are no callchains or '-g none' is specified, so conditionally
allocate it, reducing sizeof(struct hist_entry) from 210 bytes to only
96, greatly speeding the non-callchain processing.

We get absolute addresses in the events, but relative ones from the
symbol subsystem, so calculate the absolute address by asking for the
map where the symbol was found, that has the place where the DSO was
actually loaded.
For the core kernel this poses no problems if the kernel is not
relocated by things like kexec, or if we use /proc/kallsyms, but for
modules we were getting really large, negative offsets.

Due to the assumption in perf_session__new that the kernel maps would be
created using the fake PERF_RECORD_MMAP event in a perf.data file 'perf
kmem --stat caller', that doesn't have such event, ends up not being
able to resolve the kernel addresses.
Fix it by calling perf_session__create_kernel_maps() in __cmd_kmem().

Then hist_entry__fprintf will just us the newly introduced
hist_entry__snprintf, add the newline and fprintf it to the supplied
FILE descriptor.
This allows us to remove the use_browser checking in the color_printf
routines, that now got color_snprintf variants too.
The newt TUI browser (and other GUIs that may come in the future) don't
have to worry about stdio specific stuff in the strings they get from
the se->snprintf routines and instead use whatever means to do the
equivalent.
Also the newt TUI browser don't have to use the fmemopen() hack, instead
it can use the se->snprintf routines directly. For now tho use the
hist_entry__snprintf routine to reduce the patch size.

Usually "_text" is enough, but I received reports that its not always

need to apply any relocation to all the symbols in the kernel symtab,
for when, for instance, kexec is being used.

For when we are processing the events and inserting the entries in the
browser.
Experimentation here: naming "ui_something" we may be treading into
creating a TUI/GUI set of routines that can then be implemented in terms
of multiple backends.
Also the time it takes for adding things to the "browser" takes, visually
(I guess I should do some profiling here ;-) ), more time than for
processing the events...
That means we probably need to create a custom hist_entry browser, so
that we reuse the structures we have in place instead of duplicating
them in newt.
But progress was made and at least we can see something while long files
are being loaded, that must be one of UI 101 bullet points :-)

Support for the PMU's BTS features has been upstreamed in
v2.6.32, but we still have the old and disabled ptrace-BTS,
as Linus noticed it not so long ago.
It's buggy: TIF_DEBUGCTLMSR is trampling all over that MSR without
regard for other uses (perf) and doesn't provide the flexibility
needed for perf either.
Its users are ptrace-block-step and ptrace-bts, since ptrace-bts
was never used and ptrace-block-step can be implemented using a
much simpler approach.
So axe all 3000 lines of it. That includes the *locked_memory*()
APIs in mm/mlock.c as well.

when we can optimize it by first calling thread__find_addr_map

The adding of raw event support lead to complete code
refactoring. I hope is became more readable then it was.
The list of changes:
1) The 64bit config field is enough to hold all information we need
to track event details. To achieve it we used *own* enum for
events selection in ESCR register and map this key into proper
value at moment of event enabling.
For the same reason we use 12LSB bits in CCCR register -- to track
which exactly cache trace event was requested. And we cear this bits
at real 'write' moment.
2) There is no per-cpu area reserved for P4 PMU anymore. We
don't need it. All is held by config.
3) Now we may use any available counter, ie we try to grab any
possible counter.
v2:
- Lin Ming reported the lack of ESCR selector in CCCR for cache events
v3:
- Don't loose cache event codes at config unpacking procedure, we may
need it one day so no obscure hack behind our back, better to clear
reserved bits explicitly when needed (thanks Ming for pointing out)
- Lin Ming fixed misplaced opcodes in cache events

It (ab)uses the only tree widget in newt, that is actually a
checkbox tree that we use with just one option ('.'), end result
is usable but we really need to create a custom widget tree so
that we can use the data structures we have (hist_entry rb_tree

footprint by not creating a mirror set of data structures in the
newtCheckboxTree widget.

Callchains have markers inside their capture to tell we
enter a context (kernel, user, ...).
Those are not displayed in the callchains but they are
incidentally an active part of the radix tree where
callchains are stored, just like any other address.
If we have the two following callchains:
addr1 -> addr2 -> user context -> addr3
addr1 -> addr2 -> user context -> addr4
addr1 -> addr2 -> addr 5
This is pretty common if addr1 and addr2 are part of an
interrupt path, addr3 and addr4 are user addresses and
addr5 is a kernel non interrupt path.
This will be stored as follows in the tree:
addr1
addr2
/ \
/ addr5
user context
/ \
addr3 addr4
But we ignore the context markers in the report, hence
the addr3 and addr4 will appear as orphan branches:
|--28.30%-- hrtimer_interrupt
| smp_apic_timer_interrupt
| apic_timer_interrupt
| | <------------- here, no parent!
| | |
| | |--11.11%-- 0x7fae7bccb875
| | |
| | |--11.11%-- 0xffffffffff60013b
| | |
| | |--11.11%-- __pthread_mutex_lock_internal
| | |
| | |--11.11%-- __errno_location
Fix this by removing the context markers when we process the
callchains to the tree.
