Adding a generic way to use __output_copy function with
specific copy function via DEFINE_PERF_OUTPUT_COPY macro.
Using this to add new __output_copy_user function, that provides
output copy from user pointers. For x86 the copy_from_user_nmi_nochk

- exclude_callchain_kernel to filter out kernel callchain
from the sample dump

Introducing perf_output_skip function to be able to skip data
within the perf ring buffer.
When writing data into perf ring buffer we first reserve needed
place in ring buffer and then copy the actual data.
There's a possibility we won't be able to fill all the reserved
size with data, so we
Adding libunwind to be linked with perf if available. It's required
for the to get dwarf cfi unwinding support.
Also building perf with the dwarf call frame informations by default,
so that we can unwind callchains in perf itself.
Adding LIBUNWIND_DIR Makefile variable allowing user to specify
Adding following info to be parsed out of the event sample:
- user register set
- user stack dump
Both are global and specific to all events within the session.
This info will be used in the unwind patches coming in shortly.
Adding simple output printout (report -D) for both register and
stack
This brings the support for dwarf cfi unwinding on perf post
processing. Call frame informations are retrieved and then passed
to libunwind that requests memory and register content from the
applications.
Adding unwind object to handle the user stack backtrace based
on the user register values
This patch enables perf to use the dwarf unwind code.
It extends the perf record '-g' option with following arguments:
'fp' - provides framepointer based user
stack backtrace
'dwarf[,size]' - provides dwarf (libunwind) based user stack

Introducing PERF_SAMPLE_REGS_USER sample type bit to trigger
the dump of user level registers on sample. Registers we want
to dump are specified by sample_regs_user bitmask.
Only user level registers are dumped at the moment. Meaning the

Hi Linus,

Sorry. My mistake. In this case it seems that sleep functions can
be called from thread_fn, since interrupt line is disabled globally.
And nothing bad will happen if you know that device can be
