Not here, I'll check after a call:

perf cs-etm: Update record event to use new Trace ID protocol

Trace IDs are now dynamically allocated.

I'm removing this series from perf-tools-next, please address this issue
and send a v9.

I can reproduce this building failure. I am curious for how to verify
building for patch wise, the link [1] gives me some hints and below
command works for me:

$ git rebase -i --exec "make -C tools/perf clean && \
make -C tools/perf VF=1 DEBUG=1 CORESIGHT=1 && \
make -C tools/perf clean && \
make -C tools/perf VF=1 DEBUG=1" HEAD~3

Looks like perf-tools-next has some changes that has not reflected elsewhere. The ts_source patches are queued there, which is causing
the above build failure.

Mike,

Are you able to rebase your patches on perf-tools-next branch ?

Kind regards
Suzuki


Thanks,
Leo
