Hi Ingo,
Please consider pulling, this is on top of my previously submitted acme/perf/urgent, so that we can test Andi's udis86 work on 'perf script'.
This is now test built in several more docker images, including minimal feature cross-compiler builds ones:
# dm minimal-debian-experimental-x-mips64: Ok minimal-debian-experimental-x-mips64el: Ok minimal-debian-experimental-x-mipsel: Ok minimal-ubuntu-x-arm: Ok minimal-ubuntu-x-arm64: Ok minimal-ubuntu-x-ppc64: Ok minimal-ubuntu-x-ppc64el: Ok alldeps-debian: Ok alldeps-mageia: Ok alldeps-rhel7: Ok alldeps-centos: Ok alldeps-opensuse: Ok alldeps-ubuntu: Ok #
Those x-arch cross docker images already allow me to avoid introducing bugs like the powerpc one Sukadev spotted.
I need to figure out how to install more devel packages for things like libelf-devel:arch in debian/ubuntu, I almost got there with 'dpkg --add-architecture arch', but I still need to figure out how to find the list of multilib enabled devel packages to allow me to have devel packages for other arches than the native one...

perf script: Add support for printing assembler (2016-03-29 20:15:16 -0300)
---------------------------------------------------------------- perf/core improvements and fixes:
User visible:
- Add support for printing assembler using the udis86 library (Andi Kleen)
E.g.:
# perf record -e intel_pt// true # perf script -F ip,sym,asm <SNIP> ffffffff8106399d native_write_msr_safe ret ffffffff81013728 pt_config ret $0x5b81 ffffffff810139e0 pt_event_start ret ffffffff810144c3 pt_event_add jnz 0x81014489 ffffffff81014491 pt_event_add ret ffffffff8119df62 event_sched_in.isra.93 jz 0x8119df69 ffffffff8119df78 event_sched_in.isra.93 jz event_sched_in.isra.93+506 ffffffff8119e069 event_sched_in.isra.93 call 0x81c29600 <SNIP>
- Add support for skipping itrace instructions, useful to fast forward processor trace (Intel PT, BTS) to right after initialization code at the start of a workload (Andi Kleen)
- Add support for backtraces in perl 'perf script's (Dima Kogan)
- Add -U/-K (--all-user/--all-kernel) options to 'perf mem' (Jiri Olsa)
- Make -f/--force option documentation consistent across tools (Jiri Olsa)
Infrastructure:
- Add 'perf test' to check for event times (Jiri Olsa)
- 'perf config' cleanups (Taeung Song)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
---------------------------------------------------------------- Andi Kleen (3): perf tools: Add support for skipping itrace instructions perf tools: Add probing for udev86 library perf script: Add support for printing assembler
Dima Kogan (1): perf script perl: Perl scripts now get a backtrace, like the python ones
Jiri Olsa (4): perf mem: Add -U/-K (--all-user/--all-kernel) options perf tools: Make hists__collapse_insert_entry static perf tools: Make -f/--force option documentation consistent across tools perf tests: Add test to check for event times
Taeung Song (3): perf config: Remove duplicated set_buildid_dir calls perf config: Rework buildid_dir_command_config to perf_buildid_config perf config: Rename 'v' to 'home' in set_buildid_dir()
