perf-tools v6.15 tarball not uploaded?

[Michel Lind]

Hi Arnaldo,

I noticed the kernel.org mirrors don't have perf tarballs newer than
6.14.0 - https://mirrors.edge.kernel.org/pub/linux/kernel/tools/perf/

Will they be uploaded soon? Presumably I can just generate the tarball
myself for now from the Git tag.

Thanks,

Thanks! This works great on x86_64, on arm64 it's failing because some
files that are needed to generate unistd_64.h per James' commits
starting Apr 29 are not there.

(I tried copying the files that show up in the error log, but
eventually hit a wall - for the Hyperscale build I'm going to get
around it for now by just generating the file on CentOS Stream 9 and
Stream 10 VMs, but I'll try soldiering on a bit to get this fixed
properly next week)

These are the files I had to add so far for those curious

Humm, the tests are made on x86_64, i.e. the tarball ones that use the
MANIFEST file to create the tarball and then test it...

Lemme try on my rpi5, and I think I hit it before but forget about
following up on it :-(

Yeah, reproduced:

  MKDIR   /tmp/build/perf-6.15.0/libapi/fs/
  CC      /tmp/build/perf-6.15.0/libapi/fs/fs.o

We shouldn't be ever using anything outside tools, but over time we
ended up doing that :-(

And its just arm64 that is getting things from outside tools/

⬢ [acme@toolbx perf-tools]$ head tools/perf/MANIFEST 
COPYING
LICENSES/preferred/GPL-2.0
arch/arm64/tools/gen-sysreg.awk
arch/arm64/tools/syscall_64.tbl

arch/*/include/uapi/asm/bpf_perf_event.h
include/uapi/asm-generic/Kbuild
tools/perf
tools/arch
tools/scripts
⬢ [acme@toolbx perf-tools]$

James, has this appeared on your radar before?

Any idea if this can get addressed soon, and otherwise, what's the best
workaround? e.g. would copying the file generated from a checkout work?

I'm temporarily building 6.15.0 for x86_64 only for CentOS Hyperscale
(limiting it to the "facebook" variant only, until this is resolved)

https://cbs.centos.org/koji/buildinfo?buildID=61023

since some users are reporting a regression in 6.14.0 and want to test
if this is fixed:

"When trying to get a flamegraph using DCPERF_RECORD_PERF=1, the
flamegraph cannot be correctly generated."

Thanks,
