2012-05-22perf inject: Fix broken perf inject -bStephane Eranian
perf inject -b was broken. It would not inject any build_id into the stream. Furthermore, it would strip samples from the stream. The reason was a missing initialization of the event attribute structure. The perf_tool.tool.attr() callback was pointing to a simple repipe. But there was no initialization of the internal data structures to keep track of events and event ids. That later caused event id lookups to fail, and sample would get removed. The patch simply adds back the call to perf_event__process_attr() to initialize the evlist structure and now build_ids are again injected.

To match the PERF_RECORD_HEADER_TRACING_DATA record type. This is the same info as the one used for pipe mode whereas the other one is for regular file output. This will help in the later patch to add meta-data infos in pipe mode.

The following union: union { u64 val64; u32 val32[2]; } u; is used on more than one place in perf code and will be used more in upcomming patches. Adding union u64_swap to have it defined globaly so we dont need to redefine it all the time.

2012-05-22perf tools: Carry perf_event_attr bitfield throught different endiansJiri Olsa
When the perf data file is read cross architectures, the perf_event__attr_swap function takes care about endianness of all the struct fields except the bitfield flags. The bitfield flags need to be transformed as well, since the bitfield binary storage differs for both endians. ABI says: Bit-fields are allocated from right to left (least to most significant) on little-endian implementations and from left to right (most to least significant) on big-endian implementations. The above seems to be byte specific, so we need to reverse each byte of the bitfield. 'Internet' also says this might be implementation specific and we probably need proper fix and carry perf_event_attr bitfield flags in separate data file FEAT_ section. Thought this seems to work for now. Note, running following to test perf endianity handling: test 1) - origin system: # perf record -a -- sleep 10 (any perf record will do) # perf report > report.origin # perf archive perf.data - copy the perf.data, report.origin and perf.data.tar.bz2 to a target system and run: # tar xjvf perf.data.tar.bz2 -C ~/.debug # perf report > report.target # diff -u report.origin report.target - the diff should produce no output (besides some white space stuff and possibly different date/TZ output) test 2) - origin system: # perf record -ag -fo /tmp/perf.data -- sleep 1 - mount origin system root to the target system on /mnt/origin - target system: # perf script --symfs /mnt/origin -I -i /mnt/origin/tmp/perf.data \ --kallsyms /mnt/origin/proc/kallsyms - complete perf.data header is displayed Signed-off-by: Jiri Olsa <jolsa@redhat.com> Reviewed-by: David Ahern <dsahern@gmail.com> Tested-by: David Ahern <dsahern@gmail.com> Cc: Corey Ashford <cjashfor@linux.vnet.ibm.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1337151548-2396-3-git-send-email-jolsa@redhat.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2012-05-22sh: intc: Kill off special reservation interface.Paul Mundt
At present reserving the IRLs in the IRQ bitmap in addition to the dropping of the legacy IRQ pre-allocation prevent IRL IRQs from being allocated for the x3proto board. The only reason to permit reservations was to lock down possible hardware vectors prior to dynamic IRQ scanning, but this doesn't matter much given that the hardware controller configuration is sorted before we get around to doing any dynamic IRQ allocation anyways. Beyond that, all of the tables are __init annotated, so quite a bit more work would need to be done to support reconfiguring things like IRL controllers on the fly, much more than would ever make it worth the hassle.

If the file that OUTPUT_MIN_CONFIG exists then ktest.pl will prompt the user and ask them if the OUTPUT_MIN_CONFIG should be used as the starting point for make_min_config instead of MIN_CONFIG. This is usually the case, and to allow the user to do so, which is helpful if the user is creating different min configs based on tests, and they know one is a superset of another test, they can set USE_OUTPUT_MIN_CONFIG to one, which will prevent kest.pl from prompting to use the OUTPUT_MIN_CONFIG and it will just use it. If USE_OUTPUT_MIN_CONIFG is set to zero, then ktest.pl will continue to use MIN_CONFIG instead. The default is that USE_OUTPUT_MIN_CONFIG is undefined.
