Power management on laptops can be incompatible with OProfile in 2.4 (bug #554927).
-The utilities op_start, op_stop, op_dump, and op_session have been removed,
-as threatened in the last three releases. opcontrol is the replacement.
+opcontrol has a new way of specifying performance counter events. Instead of:
+opcontrol --ctr0-event=CPU_CLK_UNHALTED --ctr0-count=30000
+the new form looks like :
+The hardware counters are automatically allocated as needed.
+The post-profiling analysis tools have been massively reworked. op_time and
+oprofpp have been replaced by a single tool called opreport. This allows a
+high level of flexibity in selecting which results to profile, for example :
+opreport --symbols --exclude-symbols boring_function --threshold=5% --debug-info \
+ event:DATA_MEM_REFS session:test --merge lib \
+op_to_source has been replaced by a similar tool called opannotate, and the
+gprof output ability of oprofpp is now performed by opgprof.
+Symbols with no samples are no longer output in the results, and the default
+sort order has changed so that higher numbers are at the top. By default,
+short filenames (basename of the file) are shown instead of the full paths.
+Simple demangling is done by default.
+The new code is also significantly faster.
---rtc-value option is disabled if not in RTC mode.
+Handling of sample counts in sections with no symbols such as .plt is now
+more accurate in reporting the source of the sample.
