What toolchain and/or version are you using?
I'm using a linaro build of gcc 4.9.
aarch64-linux-gnu-gcc (Linaro GCC 4.9-2015.05) 4.9.3 20150413 (prerelease)
Linaro appear to have removed that release from their repo:
http://releases.linaro.org/components/toolchain/binaries/
So I used this one - which AFAICT is the closest to your version - to cross-build both the kernel with your config, and perf:
aarch64-linux-gnu-gcc (Linaro GCC 4.9-2016.02) 4.9.4 20151028 (prerelease)
Building perf didn't require the patch I sent due to an old gcc bug that apparently finally got fixed recently:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=28901
I then ran the resulting kernel (which still had the extra patch, so commit 0d15341 == c50837 + the patch), and perf:

Then I tried a second time - literally up-arrow, enter - and got the same exact hard hang as I get with the modern compilers the first time:

Right, at least we have one problem reproduced on both sides now.
...here.
It hung before completing that last sentence.
Perhaps the bug is exasperated by toolchain and/or host and target rootfs distribution differences? My juno target runs debian, and I recently upgraded to stretch in order to get a version of gcc that would support autoFDO.
My juno is has a debian-jessie-developer root-fs from http://releases.linaro.org/debian/images/developer-arm64/16.04/ At present I cannot build autofdo - I still have some package issues, but for perf and the kernel I am x-compiling on my ubuntu VM anyway, so the installed compilers have no effect on the perf runs,.
OK, can you try a more modern toolchain please? The one you're using isn't available anymore, AutoFDO requires gcc 5 and higher, and you're not seeing the build failures others see, but most importantly, it should make it easier to reproduce the hard lockup: at least that's the case on the Juno r2.
Thanks,
Kim

OK - tried the linaro 5.3 gcc package - this is the latest recommended compiler from the ARM connected community page for using the Linaro deliverables with Juno:-

Worked fine.
so....I'm back on the funnel / trace amount and core differences. taskset -c 2 -> selects cpu 2 -> A53(0) on both juno-r1 and juno-r2. So why on your system is the funnel for the A72 cluster (cpu 0-1) being activated. if I use taskset -c 0 (or 1) then I get the A57 cluster funnel activated as expected. (2-5 gets the A53 cluster funnel)
This seems to be indicative of some .dts issue on your system / r2. Nothing immediately obvious in the .dts that I can see.
Thanks,

I like to include dmesg | grep gcc because sometimes I myself make sloppy mistakes copying the kernel image around, but OK, I should have said I gave it a lot of time before runs: several minutes.

This seems to be indicative of some .dts issue on your system / r2. Nothing immediately obvious in the .dts that I can see.
Using the device tree compiler to show all the differences, like so:
$ dtc -I dtb -O dts -s juno.dtb > juno.dts $ dtc -I dtb -O dts -s juno-r2.dtb > juno-r2.dts $ diff -u juno.dts juno-r2.dts
We see the cpus have been renumbered such that on r2, taskset -c 2 references an A-72 (it actually happens between r0 and r1, diff r1 r2 is a simple a57->a72 rename), and phandles that coresight components reference also change, e.g., the 0x3d phandle that the etf@20140000 references used to point to the old sysctl@020000, but that node's phandle gets changed to 0x3c. Below is the full diff; is a dts patch for coresight on r1/r2 in order?
I still think there's more to it since you were able to see the inconsistent behaviour between two runs problem on r0.
Thanks,
Kim

Hi Kim,
I'm running r1 - the cs on r1 and r2 are identical - the only difference is the A57 A72 change. So I see cpu 0 and 1 as the A57, and 2-5 as the A53, I would expect the same on r2.

Worked fine.
I like to include dmesg | grep gcc because sometimes I myself make sloppy mistakes copying the kernel image around, but OK, I should have said I gave it a lot of time before runs: several minutes.
so....I'm back on the funnel / trace amount and core differences. taskset -c 2 -> selects cpu 2 -> A53(0) on both juno-r1 and juno-r2. So
why
on your system is the funnel for the A72 cluster (cpu 0-1) being
activated.
if I use taskset -c 0 (or 1) then I get the A57 cluster funnel activated
as
expected. (2-5 gets the A53 cluster funnel)
This seems to be indicative of some .dts issue on your system / r2.
Nothing
immediately obvious in the .dts that I can see.
Using the device tree compiler to show all the differences, like so:
$ dtc -I dtb -O dts -s juno.dtb > juno.dts $ dtc -I dtb -O dts -s juno-r2.dtb > juno-r2.dts $ diff -u juno.dts juno-r2.dts
We see the cpus have been renumbered such that on r2, taskset -c 2 references an A-72 (it actually happens between r0 and r1, diff r1 r2 is a simple a57->a72 rename), and phandles that coresight components reference also change, e.g., the 0x3d phandle that the etf@20140000 references used to point to the old sysctl@020000, but that node's phandle gets changed to 0x3c. Below is the full diff; is a dts patch for coresight on r1/r2 in order?
I still think there's more to it since you were able to see the inconsistent behaviour between two runs problem on r0.
Thanks,
Kim

I'm running r1 - the cs on r1 and r2 are identical - the only difference is the A57 A72 change. So I see cpu 0 and 1 as the A57, and 2-5 as the A53, I would expect the same on r2.
not so, according to this:
https://community.arm.com/dev-platforms/b/documents/posts/faq-how-do-i-chang...
r1 boots off an A57, whereas r2 boots off an A53, leading to different cpu assignments in Linux (cpu0 is the boot cpu).
Either way, if I use taskset -c 0 - for the A53 - I still see the failure, and on first try with gcc4.9-built binaries:

Worked fine.
I like to include dmesg | grep gcc because sometimes I myself make sloppy mistakes copying the kernel image around, but OK, I should have said I gave it a lot of time before runs: several minutes.
so....I'm back on the funnel / trace amount and core differences. taskset -c 2 -> selects cpu 2 -> A53(0) on both juno-r1 and juno-r2. So
why
on your system is the funnel for the A72 cluster (cpu 0-1) being
activated.
if I use taskset -c 0 (or 1) then I get the A57 cluster funnel activated
as
expected. (2-5 gets the A53 cluster funnel)
This seems to be indicative of some .dts issue on your system / r2.
Nothing
immediately obvious in the .dts that I can see.
Using the device tree compiler to show all the differences, like so:
$ dtc -I dtb -O dts -s juno.dtb > juno.dts $ dtc -I dtb -O dts -s juno-r2.dtb > juno-r2.dts $ diff -u juno.dts juno-r2.dts
We see the cpus have been renumbered such that on r2, taskset -c 2 references an A-72 (it actually happens between r0 and r1, diff r1 r2 is a simple a57->a72 rename), and phandles that coresight components reference also change, e.g., the 0x3d phandle that the etf@20140000 references used to point to the old sysctl@020000, but that node's phandle gets changed to 0x3c. Below is the full diff; is a dts patch for coresight on r1/r2 in order?
I still think there's more to it since you were able to see the inconsistent behaviour between two runs problem on r0.
Thanks,
Kim
Hi Kim,
I grabbed a Juno-r2 for an hour while the validation team where looking in the other direction :).....

I'm running r1 - the cs on r1 and r2 are identical - the only difference

the A57 A72 change. So I see cpu 0 and 1 as the A57, and 2-5 as the A53,
I
would expect the same on r2.
not so, according to this:
https://community.arm.com/dev-platforms/b/documents/posts/fa q-how-do-i-change-which-cpus-are-released-out-of-reset-and- which-one-is-the-primary-for-baremetal-development
r1 boots off an A57, whereas r2 boots off an A53, leading to different cpu assignments in Linux (cpu0 is the boot cpu).
Well that's unnecessarily confusing - but confirmed on my R2 too...

All good - at least on this R2.
The only issues I have encountered with this board and kernel are that I get an error on the PCI bus during boot, and the rear network cable does not work - I have to use the front one. Could be a new kernel issue or a h/w fault on my board. Either way CoreSight is working normally

Worked fine.
I like to include dmesg | grep gcc because sometimes I myself make sloppy mistakes copying the kernel image around, but OK, I should have said I gave it a lot of time before runs: several minutes.
so....I'm back on the funnel / trace amount and core differences. taskset -c 2 -> selects cpu 2 -> A53(0) on both juno-r1 and juno-r2.
So
why
on your system is the funnel for the A72 cluster (cpu 0-1) being
activated.
if I use taskset -c 0 (or 1) then I get the A57 cluster funnel
activated
as
expected. (2-5 gets the A53 cluster funnel)
This seems to be indicative of some .dts issue on your system / r2.
Nothing
immediately obvious in the .dts that I can see.
Using the device tree compiler to show all the differences, like so:
$ dtc -I dtb -O dts -s juno.dtb > juno.dts $ dtc -I dtb -O dts -s juno-r2.dtb > juno-r2.dts $ diff -u juno.dts juno-r2.dts
We see the cpus have been renumbered such that on r2, taskset -c 2 references an A-72 (it actually happens between r0 and r1, diff r1 r2 is a simple a57->a72 rename), and phandles that coresight components reference also change, e.g., the 0x3d phandle that the etf@20140000 references used to point to the old sysctl@020000, but that node's phandle gets changed to 0x3c. Below is the full diff; is a dts patch for coresight on r1/r2 in order?
I still think there's more to it since you were able to see the inconsistent behaviour between two runs problem on r0.
Thanks,
Kim

So, running the stuff as usual, gcc 6.x built kernel and perf, as root and as my user login via sudo, various cores
gcc, kernel, and perf versions aren't shown below again. I also don't see sudo being used.

All good - at least on this R2.
Well I _consistently_ get the hard lockup on first try.
One obvious difference is my runs get funnel messages, whereas yours don't. Is that due to my building with DEBUG=5? Can you try building your perf like this then?:
make -C perf NO_LIBDW_DWARF_UNWIND=1 NO_LIBUNWIND=1 NO_LIBBPF=1 NO_LIBELF=1 NO_SDT=1 NO_LOCAL_LIBUNWIND=1 NO_LIBAUDIT=1 NO_LIBCRYPTO=1 NO_GTK2=1 NO_SLANG=1 NO_LIBPYTHON=1 NO_LIBPERL=1 NO_JVMTI=1 DEBUG=5
You continue to not mention trying with a time delay in between your runs. Can you wait several minutes between runs?
Here are the list of differences we should double-check:
- device tree - juno-r2.dtb from commit c508373874 - distro (i.e., libc): Debian 9 stretch:
--- root@juno:~# ldd ./perf linux-vdso.so.1 (0x0000ffff8afe8000) libpthread.so.0 => /lib/aarch64-linux-gnu/libpthread.so.0 (0x0000ffff8afac000) librt.so.1 => /lib/aarch64-linux-gnu/librt.so.1 (0x0000ffff8af95000) libm.so.6 => /lib/aarch64-linux-gnu/libm.so.6 (0x0000ffff8aeea000) libdl.so.2 => /lib/aarch64-linux-gnu/libdl.so.2 (0x0000ffff8aed7000) libc.so.6 => /lib/aarch64-linux-gnu/libc.so.6 (0x0000ffff8ad8d000) /lib/ld-linux-aarch64.so.1 (0x0000aaaab6360000) ---
Can you provide your details?
- firmware (see below log) - kernel config - gcc: I can reproduce with Linaro's 4.9.4:
--- root@juno:~# dmesg | grep gcc [ 0.000000] Linux version 4.11.0-rc1-g0d15341 (kim@dupont) (gcc version 4.9.4 20151028 (prerelease) (Linaro GCC 4.9-2016.02) ) #3 SMP PREEMPT Tue Mar 14 22:41:34 CDT 2017 root@juno:~# strings -a ./perf | grep "GCC" GCC: (Linaro GCC 4.9-2016.02) 4.9.4 20151028 (prerelease) ---
My entire session log, from firmware start, is below. I didn't have any PCI badness and only use the front networking port. IIRC, those can be kernel config related, and since I'm using your kernel config, and not seeing these problems, I'd have to ask to see whether your dmesg matches?
Also, can you confirm the OOM when enabling the sinks prior to perf invocation? If all else fails, can we work on fixing that problem?
Thanks,
Kim

Hi Kim,
This thread is now getting a bit unwieldy with all the inlined extensive logging. Also we are considerably off topic - no longer about perf inject, but more about simply getting the CS infrastructure working in your environment. At this point it appears that google mail is not correctly showing all the previous mail so I cannot all the answers at your questions. I have attached my boot log from the serial terminal for my r2 run. I was using the 'screen' serial terminal monitor with logging enabled. The log is tricky to read in places as the backspaces end up a special characters and repeated incrementing count message appears which stayed stationary in the serial window
It may be worth starting a new mail thread?
Some additional answers inline.

So, running the stuff as usual, gcc 6.x built kernel and perf, as root
and
as my user login via sudo, various cores
gcc, kernel, and perf versions aren't shown below again. I also don't see sudo being used.
gcc & kernel version as per 2nd line of boot log above (well would be if google mail was properly showing it), and see attached boot log .txt file. gcc version 6.2 from the linaro toolchain dir. Perf version is unchanged as previously mentioned. I'm building off the opencsd-perf-4.11-rc1 branch.

All good - at least on this R2.
Well I _consistently_ get the hard lockup on first try.
One obvious difference is my runs get funnel messages, whereas yours don't.
This is due to the fact that the logging messages are appearing on the uart serial terminal. I mainly run in an addtional login terminal I have ssh'd into on the juno box. This separates the perf messages above and the dmesg type driver logging onto separate terminals.
Is that due to my building with DEBUG=5? Can you try building your perf like this then?:
make -C perf NO_LIBDW_DWARF_UNWIND=1 NO_LIBUNWIND=1 NO_LIBBPF=1 NO_LIBELF=1 NO_SDT=1 NO_LOCAL_LIBUNWIND=1 NO_LIBAUDIT=1 NO_LIBCRYPTO=1 NO_GTK2=1 NO_SLANG=1 NO_LIBPYTHON=1 NO_LIBPERL=1 NO_JVMTI=1 DEBUG=5
You continue to not mention trying with a time delay in between your runs. Can you wait several minutes between runs?
If you look at the serial log you will see various time between runs.
Here are the list of differences we should double-check:
- device tree - juno-r2.dtb from commit c508373874
as per the buiild branch in opencsd.
- distro (i.e., libc): Debian 9 stretch:
I'm using a pre-built debian-jessie-developer rootfs from linaro - see previous earlier point in mail thread for location.
root@juno:~# ldd ./perf linux-vdso.so.1 (0x0000ffff8afe8000) libpthread.so.0 => /lib/aarch64-linux-gnu/libpthread.so.0 (0x0000ffff8afac000) librt.so.1 => /lib/aarch64-linux-gnu/librt.so.1 (0x0000ffff8af95000) libm.so.6 => /lib/aarch64-linux-gnu/libm.so.6 (0x0000ffff8aeea000) libdl.so.2 => /lib/aarch64-linux-gnu/libdl.so.2 (0x0000ffff8aed7000) libc.so.6 => /lib/aarch64-linux-gnu/libc.so.6 (0x0000ffff8ad8d000) /lib/ld-linux-aarch64.so.1 (0x0000aaaab6360000)
Can you provide your details?
- firmware (see below log)
See attached log [r2-boot.txt]- one immediate difference is that I use u-boot rather than UEFI.
- kernel config
- gcc: I can reproduce with Linaro's 4.9.4:
root@juno:~# dmesg | grep gcc [ 0.000000] Linux version 4.11.0-rc1-g0d15341 (kim@dupont) (gcc version 4.9.4 20151028 (prerelease) (Linaro GCC 4.9-2016.02) ) #3 SMP PREEMPT Tue Mar 14 22:41:34 CDT 2017 root@juno:~# strings -a ./perf | grep "GCC" GCC: (Linaro GCC 4.9-2016.02) 4.9.4 20151028 (prerelease)
My entire session log, from firmware start, is below. I didn't have any PCI badness and only use the front networking port. IIRC, those can be kernel config related, and since I'm using your kernel config, and not seeing these problems, I'd have to ask to see whether your dmesg matches?
I cannot explain the PCI issue on that r2 board. Not seen it previously in testing - but might be a different board than the one I used last time.
Also, can you confirm the OOM when enabling the sinks prior to perf invocation? If all else fails, can we work on fixing that problem?
I can double check this when I get into the office tomorrow, but I expect it will still be there as I could reproduce on r1 + gcc 4.9. This is worth investigating a some point, but surely secondary to you figuring out why you are hitting a hard crash.
Regards
Mike

I see that was done for the kernel splat for running perf without enabling sinks. I'm going to just say I'd expect perf to run the same way every time, the same way 'ls' runs, no matter what underlying h/w is in use. AFAICT, Coresight is currently the only device that makes perf have this 'unnatural' behaviour. E.g., the fact that sinks have to be turned on outside of perf, only to have perf in turn, turn *off* those same sinks, I consider asymmetric behaviour and poor design in terms of a perf user's expected usage.
Also, can you confirm the OOM when enabling the sinks prior to perf invocation? If all else fails, can we work on fixing that problem?
I can double check this when I get into the office tomorrow, but I expect it will still be there as I could reproduce on r1 + gcc 4.9. This is worth investigating a some point, but surely secondary to you figuring out why you are hitting a hard crash.
OK, I've trimmed out all the nitty gritty details where we were trying to compare setups, mainly because I've reached a point where I can finally run an ETM trace without locking up the machine (without having to buy an SSD for an older operating system's rootfs :).
Recipe for success - at least for this juno R2 user - is:
- Use upstream Linus' ToT as source for kernel (not OpenCSD's tree/branches). This commit (093b995) works for me, built with ubuntu's standard gcc 6.2 cross compiler:

Is this the expected overhead, given the (85 - 82) / 85 = 3.5% success rate of capturing and storing the trace data? I'd expect a lot more than 5MB of trace for the incurred 2.5x execution time (8 seconds in this case). I can't help but imagine those funnel printk's have a negative influence in the area...

That was the initial design, but has now been changed to allow the sink to be specifed on the perf command line. We are in the process of changing the kernel docs to state this, matching the OpenCSD howto docs.
Also, can you confirm the OOM when enabling the sinks prior to perf invocation? If all else fails, can we work on fixing that problem?

The "loss" in this case is a flag indicator that the 64k ETF is wrapping. So there is some data loss, but you do get a full 64k buffer each time. You should get less loss if you use the ETR.

Linaro uses gmail, last I knew. ARM now uses microsoft's cloud, and allows non-web based access to that, so I think there's a bug in the IT dept. policy if they think allowing microsoft access

I'd expect a lot more than 5MB of trace for the incurred 2.5x execution time (8 seconds in this case). I can't help but imagine those funnel printk's have a negative influence in the area...
The "loss" in this case is a flag indicator that the 64k ETF is wrapping. So there is some data loss, but you do get a full 64k buffer each time. You should get less loss if you use the ETR.
combining that with your comment from the other thread:
Don't enable the sink using sysfs, specify the sink on the perf command line and use the up arrow as much as you like.
and searching for etr in the current documentation, I assume you mean I should execute perf like this?:

Two things can happen here:

There lies the problem - in mainline the ETR driver doesn't have support for the perf API. Coincidentally Mike is working on this. The perf-opencsd-4.11-rc1 has an ancient (and inefficient) ETR driver that does support the perf API.

OK. Returning -ENOTSUPP with wording to such effect on dmesg would be more helpful than 'failed to mmap' (although it's admittedly better than a stack trace).
The perf-opencsd-4.11-rc1 has an ancient (and inefficient) ETR driver that does support the perf API.
Odd, because I was told to use ETR for its superior efficiency.

The IP block itself is much better than anything else, that is very true but the current driver implementation isn't. On the flip side what is currently there in perf-opencsd-4.11-rc1 allows people to use the ETR with perf while Mike is working away.
perf-opencsd-4.11-rc1 locks up my machine though:
That is very very odd. I have a Juno R2 coming my way but won't have the opportunity to fire it up until (at least) April 17th.

For the record, I've since found out that this method uses the ETB trace method, and actually produces zero valid trace data in the resulting perf.data file. It turns out that pointing create_gcov to an empty-but-valid samples perf.data file produces an empty-but-valid .gcov file, and, in turn, using that to recompile sort.c with -fauto-profile magically produces a better performing resulting executable.
So I still can't get any sort (pun intended) of trace data out of my debian-based Juno r2.

I've been able to get past the hard-lockup situation when capturing ETM data by upgrading my Juno R2's firmware to the latest (Jan 2017).
However, sadly, I am still unable to replicate the results demonstrated in the AutoFDO instructions. When using host (cross) built tools, I see no improvement in performance:

In trying to eliminate any arch-dependent code in the tools, I discovered perf inject fails when built and run on the Juno target itself.
See the 'failed to process type' message when running inject on native built OpenCSD 4.11 branch perf with OpenCSD master branch libs:

Maybe the problem is with the fact that perf inject does not translate the ETM trace into LBR events? Here is the command that I was using: $ perf inject -i perf.data -o inj.data --itrace=i100usl --strip

Oh, I see this error now. Maybe you can launch gdb on perf-inject and see where this assert is triggered, and add code to handle/discard that opcode.

I haven't done anything to warrant that: I was just trying to follow the AutoFDO instructions from Documentation/trace/coresight.txt:

The following session is using a native-built perf based on the OpenCSD tree's perf-opencsd-4.11 commit e0cf71ef149f:
$ gcc -O3 sort.c -o sort $ taskset -c 2 ./sort Bubble sorting array of 30000 elements 5311 ms $ perf --version perf version 4.10.rc4.ge0cf71 $ perf record -e cs_etm/@20070000.etr/u --per-thread taskset -c 2 ./sort Error: failed to set config "20070000.etr" on event cs_etm/@20070000.etr/u with 13 (Permission denied)

Obviously there are missing keywords like 'sudo' (or '#' prompts instead of '$' prompts) in the instructions.
Even with the inject command provided in the last reply, I still get the error:
$ sudo perf inject -f -i perf.data -o inj.data --itrace=i100usl --strip 0x350 [0x50]: failed to process type: 1
I even went back to try the 4.11-rc1 branch, and get the same error.
That's all with native-built perf: something the instructions seem to imply: e.g., there are no instructions saying when to go in between the host and the target machines.
When trying to do the cross-built perf inject with OpenCSD libraries (also not mentioned in the instructions, nor does inject complain if not built without them), things start to work a bit better in that the "failed to process type: 1" error does not occur.
So it would have been better to have been provided more exact instructions on how to run the AutoFDO example, but now I'm seeing a different problem:
Given this excerpt of my version of sort.c (it has been modified):

I see this gcov generated with the intel-pt trace data:

which makes an improvement:

but the aarch64 version does not - in fact it makes things worse:

Any ideas?

I wonder why the profile you get on aarch64 looks so different than the x86_64. Could you please use the x86_64 profile when optimizing with autoFDO for aarch64? Also could you please use the aarch64 profile to optimize the x86_64 program, and report the execution time numbers?
Also what version of gcc are you using?

This may be a problem in tuning of the aarch64 optimizations in the compiler.
the arch-independent gcov file merely suggests what paths are more or less likely, and I've seen the aarch64 compiler backend honour a likely branch, given a coverage file derived with software instrumentation: on juno r2:
$ gcc -O3 -o sort-O3 sort.c $ taskset -c 2 ./sort-O3 Bubble sorting array of 30000 elements 5303 ms $ gcc -O3 -o sort-O3-profgen -fprofile-generate sort.c $ taskset -c 2 ./sort-O3-profgen 3000 Bubble sorting array of 3000 elements 44 ms $ gcc -O3 -o sort-O3-profopt -fprofile-use sort.c $ taskset -c 2 ./sort-O3-profopt Bubble sorting array of 30000 elements 3884 ms
so it's not that the aarch64 backend isn't doing the right thing wrt branch optimization.

I have to pack my juno now, so I'll have get to that later, but I don't think it'll tell us anything new: the x86 gcov is good whereas the arm one is bad, and they are arch-independent. Your results (from the documentation) also suggest the compiler(s) is/are working properly.
Also what version of gcc are you using?
native target/juno: gcc (Debian 6.3.0-14) 6.3.0 20170415
host/x86: aarch64-linux-gnu-gcc (Ubuntu 6.2.0-5ubuntu12) 6.2.0 20161005

I think you are right, there may be some bug in creating the coverage file from the ETM traces. I will have a look at this.

perf tools: new inject capabilitity for CoreSight traces
Added user space perf functionality to translate CoreSight traces into last branch stack events. To invoke the new functionality, use the perf inject tool with --itrace=il. For example, to translate the ETM trace from perf.data into last branch records in a new inj.data file:
The parameter to 'l' 128 is parsed as recording the last 128 branches from the sampling point. Also note that right now the parameter to 'i' 100us is ignored, and we end up translating all the branches in the trace.

I am not able to reproduce the error on Juno-r0 with the perf.data from Kim. I rebuilt the ETM decoder from master as of today 054c07caa2eb06ae74426b79cb3875bf2569d091 linux perf as indicated at sha e0cf71e.

Now, let's investigate why the coverage samples are different on x86_64 and aarch64.
Here is again the source code for the hot code:
void bubble_sort (int *a, int n) { int i, t, s = 1; while (s) { s = 0; for (i = 1; i < n; i++) { // the condition and the inner loop are hot. if (a[i] < a[i - 1]) { // the code in the "then clause" is colder than the condition, // as most of the elements get sorted over time and do not need to be swapped. t = a[i]; a[i] = a[i - 1]; a[i - 1] = t; s = 1; } } } }
The coverage on aarch64:
6: bubble_sort total:684721 2: 138 4: 1 5: 0 7: 130873 9: 553709
"7:" is the code in the "then clause". This is colder than "9:". "9:" is the code of the innermost loop and the condition "a[i] < a[i-1]".
Looking at the assembler generated by gcc for aarch64, the inner loop is in L3 and L4:
# gcc -O3 sort.c -S -o - [...] bubble_sort: sub w5, w1, #2 add x5, x5, 1 add x5, x0, x5, lsl 2 .p2align 2 .L2: cmp w1, 1 // cold outer loop ble .L1 mov x2, x0 mov w6, 0 .p2align 2 .L4: ldp w4, w3, [x2] // hot inner loop cmp w3, w4 // hot bge .L3 // hot mov w6, 1 // colder code in "then clause" stp w3, w4, [x2] // colder code .L3: add x2, x2, 4 // hot cmp x2, x5 // hot bne .L4 // hot cbnz w6, .L2 // cold outer loop .L1: ret [...]
and here is what GCC generates for x86_64 $ gcc -O3 sort.c -S -o - [...] bubble_sort: .LFB40: .cfi_startproc leal -2(%rsi), %eax leaq 8(%rdi,%rax,4), %r8 .p2align 4,,10 .p2align 3 .L2: cmpl $1, %esi jle .L1 leaq 4(%rdi), %rax xorl %r9d, %r9d .p2align 4,,10 .p2align 3 .L4: movl (%rax), %edx movl -4(%rax), %ecx cmpl %ecx, %edx jge .L3 movl %ecx, (%rax) movl %edx, -4(%rax) movl $1, %r9d .L3: addq $4, %rax cmpq %r8, %rax jne .L4 testl %r9d, %r9d jne .L2 .L1: rep ret [...]
Here is the x86_64 coverage.
6: bubble_sort total:774914 2: 29 4: 195863 5: 195415 7: 93872 8: 93872 9: 195863
It seems to me that the debug info may be more precise on x86_64 than on aarch64, and create_gcov is able to identify in a more precise way which instruction belongs to which basic block in a more fine grain way than on aarch64. For example, "4:" and "9:" have the exact same number of event samples, and the same is true for "7:" and "8:". These may be because some instructions get tagged in the debug info as belonging to different basic blocks.
I'm adding Dehao to the "CC:" list to check my interpretation of what create_gcov does differently on x86_64 than on aarch64.
Thanks, Sebastian

Thanks Kim. I got your perf.data and I will try to see why the perf inject "compiler" crashes on aarch64.
I am not able to reproduce the error on Juno-r0 with the perf.data from Kim. I rebuilt the ETM decoder from master as of today 054c07caa2eb06ae74426b79cb3875bf2569d091 linux perf as indicated at sha e0cf71e.

There is only one LBR event which does not have a branch stack.

Now, let's investigate why the coverage samples are different on x86_64 and aarch64.
Here is again the source code for the hot code:
void bubble_sort (int *a, int n) { int i, t, s = 1; while (s) { s = 0; for (i = 1; i < n; i++) { // the condition and the inner loop are hot. if (a[i] < a[i - 1]) { // the code in the "then clause" is colder than the condition, // as most of the elements get sorted over time and do not need to be swapped. t = a[i]; a[i] = a[i - 1]; a[i - 1] = t; s = 1; } } } }
The coverage on aarch64:
6: bubble_sort total:684721 2: 138 4: 1 5: 0 7: 130873 9: 553709
"7:" is the code in the "then clause". This is colder than "9:". "9:" is the code of the innermost loop and the condition "a[i] < a[i-1]".
Looking at the assembler generated by gcc for aarch64, the inner loop is in L3 and L4:
# gcc -O3 sort.c -S -o - [...] bubble_sort: sub w5, w1, #2 add x5, x5, 1 add x5, x0, x5, lsl 2 .p2align 2 .L2: cmp w1, 1 // cold outer loop ble .L1 mov x2, x0 mov w6, 0 .p2align 2 .L4: ldp w4, w3, [x2] // hot inner loop cmp w3, w4 // hot bge .L3 // hot mov w6, 1 // colder code in "then clause" stp w3, w4, [x2] // colder code .L3: add x2, x2, 4 // hot cmp x2, x5 // hot bne .L4 // hot cbnz w6, .L2 // cold outer loop .L1: ret [...]
and here is what GCC generates for x86_64 $ gcc -O3 sort.c -S -o - [...] bubble_sort: .LFB40: .cfi_startproc leal -2(%rsi), %eax leaq 8(%rdi,%rax,4), %r8 .p2align 4,,10 .p2align 3 .L2: cmpl $1, %esi jle .L1 leaq 4(%rdi), %rax xorl %r9d, %r9d .p2align 4,,10 .p2align 3 .L4: movl (%rax), %edx movl -4(%rax), %ecx cmpl %ecx, %edx jge .L3 movl %ecx, (%rax) movl %edx, -4(%rax) movl $1, %r9d .L3: addq $4, %rax cmpq %r8, %rax jne .L4 testl %r9d, %r9d jne .L2 .L1: rep ret [...]
Here is the x86_64 coverage.
6: bubble_sort total:774914 2: 29 4: 195863 5: 195415 7: 93872 8: 93872 9: 195863
It seems to me that the debug info may be more precise on x86_64 than on aarch64, and create_gcov is able to identify in a more precise way which instruction belongs to which basic block in a more fine grain way than on aarch64. For example, "4:" and "9:" have the exact same number of event samples, and the same is true for "7:" and "8:". These may be because some instructions get tagged in the debug info as belonging to different basic blocks.
I'm adding Dehao to the "CC:" list to check my interpretation of what create_gcov does differently on x86_64 than on aarch64.
Could you copy-paste the code with line number (the one you pasted does not match the profile). Could you also provide the the assembly of the -g1 arm binary so that I can examine the debug info?
Also, it would be helpful if you can use sample_merger to generate the text version of the perf.data file and attach that to the thread too (as well as the full objdump of the bubble_sort function). This will help evaluate if profile is accurate at binary level.
Thanks, Dehao
Thanks, Sebastian

looks like 400888 is not jumping to 40088c, but 4005a0 instead. and 40088c is not even a jump instruction.

Hi,
The OpenCSD decoder outputs executed instruction ranges - which do look very much like the branch stack ranges below. These ranges are inclusive to exclusive addresses.
I'm not familiar with the required from format of the branch stack, but assuming this is a range output by the decoder....
..... 29: 00000000004005a0 -> 00000000004005b0 0 cycles P 0
it means that we traced execution starting at the instruction @ 4005a0 to the instruction _before_ address 4005b0 (i.e. the instruction @ 4005ac if aarch32 / aarch64, or the instruction @ 4005ae if Thumb16).

@29 is the execution of the code @4005a0 @30 executes the bl 4005a0 @31 runs from 40088c to the b.ne 400888 @ 400894 thus looping round again.
So perhaps the interpretation of the output from the decoder in building the branch stack could be the issue here?

I see, in this output, branch_stack is more like "range_list". I think they provides equivalent info, but the profile processing tool can only interpret the branch_stack. So we either need to teach the profile processing tool to understand the range_list, or make the profiler convert range_list to branch_stack.

So perhaps the interpretation of the output from the decoder in building the branch stack could be the issue here?
Mike, I think you are right: my interpretation of the ETM trace was wrong. The ETM trace contains the boundaries of the executed basic blocks, and not the start and end addresses of the branch instructions as in the LBR branch stack. The conversion from the ETM to LBR events is not a 1-to-1 translation as currently implemented. I will submit a patch to fix this in perf inject.
Thanks Kim, Dehao, and Mike for your help on identifying this issue.

Hi Sebastian,
You should be further aware due to the way that the program flow trace works, all branches will result in a trace range, but not all trace ranges end in a branch. The input packets from the decoder [struct ocsd_generic_trace_elem @trc_gen_elem_types.h] contain the trace range as you have seen plus information on the last instruction in that range:- a) if it was a branch or not b) if it was executed (i.e. branch taken or not).
However this additional information is not transferred into the internal cs_etm_packet structure used in cs_etm__update_last_branch_rb()
So unless I have mis-interpreted what is required, to build a correctly formatted last branch record series, this additional information is going to be required - (we don't want none-branch ranges?), meaning an update in the cs-etm-decoder.c code is also required.
Regards
Mike

it means that we traced execution starting at the instruction @ 4005a0 to the instruction _before_ address 4005b0 (i.e. the instruction @ 4005ac if aarch32 / aarch64, or the instruction @ 4005ae if Thumb16).

To my understanding ETM has no overhead on the execution: ETM is a hardware device that was designed for debug purposes to have no overhead. The normal use of the ETM is to be able to inspect an execution trace leading to an error (like a kernel panic.) At the moment of the crash, one can stop the execution and inspect the trace recorded by the ETM.
In the use of the ETM with "perf record", there is an overhead when "perf record" wakes up to record the trace. Copying the content of the trace buffer (ETB) to perf.data has an overhead, that can be mitigated by making perf to wake up less often to record a trace, and by using a small ETB. I have tried an ETB of 1MB and 3MB, and I do not know whether one can configure the ETB to be smaller than 1MB.
I will let the experts Mike and Mathieu comment more on the overhead of the ETM.

Sebastian has properly summarised the situation. ETMs don't introduce overhead since they are HW devices. Depending on the sink being used there may be more or less overhead. Due to their inherent nature ETB and ETF sinks come along with extra processing related to copying traces from the internal memory to the perf ring buffer. That can be mitigated by using an ETR sink in scatter-gather mode. There is currently an implementation on github with another one to be posted to the kernel mailing list soon.

looks like 400888 is not jumping to 40088c, but 4005a0 instead. and 40088c is not even a jump instruction.
