Hi all,
I am trying off Target Trace Decoding using arm-cs-trace-disasm.py but it doesn’t show
proper disassembly. There is unexpected warning "could not read first record".
Any pointers on what the issue could be?
Meanwhile I am trying to do trace decoding on aarch64 target and see if that helps.
I have taken simple example mentioned in [1].
.pdf http://events17.linuxfoundation.org/sites/events/files/slides/ELC-E1 6.pdf
#include int coresight_test1(int val);
int main(void) {
int val; val = coresight_test1(10);
printf("val: %d\n", val);
return 0;
}
perf record -e cs_etm/@tmc_etf0/u --filter 'filter0x5a8/0x5e4@/home/root/libcstest.so.1.0' --per-thread ./main
tar czf cs_example.tgz perf.data ~/.debug
Off Target Trace Decoding: “perf report”
tar xf cs_example.tgz
$ rm -rf ~/.debug // remove previous trace data
$ cp -dpR .debug ~/ // copy the current trace data
$ perf report --stdio
linux-xlnx/tools/perf/perf --exec-path= <snip>/linux-xlnx/tools/perf script tools/perf/scripts/python/arm-cs-trace-disasm.py -- -d ${XTOOL_PATH}/aarch64-linux-gnu-objdump -v
I believe the perf script doesn't work with coresight trace decoding as we need a two pass approach for decoding the stream for figuring out the parameters for the queues. James Clark can give you the exact
reason.

No that script is still working, I just tried it on and off target and it's all fine.
I didn't use --exec-path=, I'm not sure why that's in that linked pdf, but it didn't cause the same issue that you see if I added it.
The "could not read first record" errors actually come from the addr2line part of Perf rather than this script. Do you have perf report/annotate working without the script?
I tried perf capture and report on aarch64 target platform (To avoid any possible cross-platform issue) With that perf report seems working but perf annotate is not working. Any suggestions on what could be the issue?
Which features do you have compiled into Perf? If you don't have libelf and some others then annotate won't work:

Or does something like this work:
$ echo "12345" | addr2line -e \ ~/.debug/.build- id/b7/b30ba2c0f618615a8d32d86813718bb2fdb567/debug
fpioconst.c:?
I also just set the path to objdump directly rather than with a variable, but I assume XTOOL_PATH is set? Although I think it must be because you get a different error if objdump is missing.
-d /usr/bin/aarch64-linux-gnu-objdump
