-----------------------------------------------------------------------

OProfile 1.0.0 has been released. A major change in this release
is the removal of the legacy opcontrol-based profiler. The legacy
profiling tool has been deprecated since release 0.9.8 when operf
was first introduced. The following components and processor types
that were dependent on opcontrol have also been removed:

   - GUI component (i.e., oprof_start)
   - IBS events removed from AMD processors
   - All Alpha processors, except for EV67 (which *is* supported by operf/ocount)
   - Architecture avr32
   - Architecture ia64
   - Processor model IBM Cell
   - Processor model P.A. Semi PA6T
   - RTC (real time clock mode)

OProfile users still running on any of these affected systems or
needing any of the removed components listed above should not upgrade
to OProfile release 1.0. Alternatively, you can obtain all of the new
features, enhancements, and bug fixes described below and still have
access to opcontrol by doing the following:

	git clone git://git.code.sf.net/p/oprofile/oprofile oprofile
	cd oprofile
	git checkout PRE_RELEASE_1_0

and then build/install as usual.

Incompatibilities with previous release
---------------------------------------

- Sample data collected with previous releases of OProfile are incompatible
  with release 1.0.
- ophelp schema: Major version changed for removal of unit mask 'extra'
  attribute and addition of unit mask 'name'.

-------------------------------------------------------------------------

Other bug fixes and improvements without a filed report (e.g., posted to the list):
---------------
   - Fix behavior and documentation for '--threshold' option
   - Remove hard-coded timeout for JIT dump conversion
   - Update Alpha EV67 CPU support and remove all other Alpha CPU support
   - operf main process improperly killing conversion process
   - Fix up S390 support to work with operf/ocount
   - Link ocount with librt for clock_gettime only when needed
   - Fix 'Invalid argument' running 'opcontrol --start --callgraph=<n>' in
     Timer mode
   - Allow root to remove old jitdump files from /tmp/.oprofile/jitdump
   - Remove opreport warnings for /no-vmlinux, [vdso], [hypervisor_bucket]
     not found
   - Fix event codes for marked architected events (IBM ppc64)
   - Make operf/ocount detect invalid timer mode from opcontrol
   - Reduce overhead of operf waiting for profiled app to end
   - Fix "Unable to open cpu_type file for reading" for IBM POWER7+
   - Allow all native events for IBM POWER8 in POWER7 compat mode
   - Fix spurious "backtraces skipped due to no file mapping" log entries
   - Fix the units for the reported CPU frequency


Known problems and limitations
-------------------------
- When using operf to profile multiple events, the absolute number of
  events recorded may be substantially fewer than expected. This can be
  due to known bug in the Linux kernel's Performance Events Subsystem that
  was fixed sometime between Linux kernel version 3.1 and 3.5.
