The quiet infrastructure was moved out of Makefile.build to accomidate the new syscall table generation scripts in perf. Syscall table generation wanted to also be able to be quiet, so instead of again copying the code to set the quiet variables, the code was moved into Makefile.perf to be used globally. This was not the right solution. It should have been moved even further upwards in the call chain. Makefile.include is imported in many files so this seems like a proper place to put it.

Commit f2868b1a66d4 ("perf tools: Expose quiet/verbose variables in Makefile.perf") moved the quiet infrastructure out of tools/build/Makefile.build and into the top-level Makefile.perf file so that the quiet infrastructure could be used throughout perf and not just in Makefile.build.
Extract out the quiet infrastructure into Makefile.include so that it can be leveraged outside of perf.

Sorry, I overlooked this part and merged a change that touched the common files into the perf tree.
f2868b1a66d4f40f ("perf tools: Expose quiet/verbose variables in Makefile.perf")
Unfortunately, it's already in v6.14-rc1.
Can you explain how it breaks it? Currently bpftool and resolve_btfids don't build quietly so this was an attempt to fix that.
So I think you will need something like this for v6.14. Again, sorry about the trouble.
Thanks, Namhyung

Nack. libbpf and bpftool are synced independently to github and released from there. This change breaks it.
Sorry, I overlooked this part and merged a change that touched the common files into the perf tree.
f2868b1a66d4f40f ("perf tools: Expose quiet/verbose variables in Makefile.perf")
Unfortunately, it's already in v6.14-rc1.
Can you explain how it breaks it? Currently bpftool and resolve_btfids don't build quietly so this was an attempt to fix that.
So I think you will need something like this for v6.14. Again, sorry about the trouble.
Just revert f2868b1a66d4f40f that created this mess.
Why are you opposed to unifying this helpers among the various projects in tools? Can you explain what about this breaks the Github syncing flow and why it cannot be resolved? It doesn't make sense to duplicate "Q=" in every Makefile anybody ever wants to add to tools just because bpf syncing isn't robust.

The quiet infrastructure was moved out of Makefile.build to accomidate the new syscall table generation scripts in perf. Syscall table generation wanted to also be able to be quiet, so instead of again copying the code to set the quiet variables, the code was moved into Makefile.perf to be used globally. This was not the right solution. It should have been moved even further upwards in the call chain. Makefile.include is imported in many files so this seems like a proper place to put it.

Alexei's concern about Github mirrors of bpftool and libbpf isn't valid. Github versions of those projects use their own independent Makefiles anyways, so your change doesn't break that aspect.
But your change *does* break both libbpf's and bpftool's make output *in the kernel repo*. With this patch we basically don't have "quiet" mode anymore:

Thanks, b4 didn't pick this one, probably because you provided the Ack for a previous version of this series, but the patch in it is the same as in v2, so I'm keeping it, ok?
Also since you applied the patches and tested it, can I promote the tag to Tested-by you?
Humm, there is a slight difference, checking that in the e-mails thread...
+ quiet = quiet_ + Q = @
