Hi all,
After merging the tip tree, today's linux-next build (powerpc64le perf)
failed like this:
make[3]: *** No rule to make target '/home/sfr/next/perf/arch/x86/include/generated/asm/syscalls_64.c', needed by '/home/sfr/next/perf/util/syscalltbl.o'. Stop.
(I build in /home/sfr/next/next with objects in /home/sfr/next/perf.)
Presumably caused by commit
1b700c997500 ("perf tools: Build syscall table .c header from kernel's syscall_64.tbl")
I have reverted that commit for today (which fixes my build problem but
may not be overall correct).

I'll check, should've been caught by a cross compiler build for ppc64le
I have in place :-\
minimal-ubuntu-x-ppc64el: Ok
But maybe not, as this requires audit-libs-devel and that is not present
on that minimal ubuntu x-compiler setup, sigh :-\

Hi acme,
I have a jenkins which builds perf on ppc64le, but it only builds Linus' tree
and linux-next.
Which branch in your tree should I be building in order to catch problems like
this, perf/core ?
https://git.kernel.org/cgit/linux/kernel/git/acme/linux.git/log/?h=perf/core
cheers

yes, please, I use two normally, one for devel stuff, perf/core, and
perf/urgent when sending stuff to the current merge window.
I'll continue trying to get a local, more complete, cross compiler
environment, need to look again at how that multiarch stuff is in
debian...

Right, I'm trying to figure out how to bet fix that, one way would be to
do:
diff --git a/tools/perf/util/Build b/tools/perf/util/Build
index 85a9ab62e23f..7fc4ac304ed6 100644
--- a/tools/perf/util/Build
+++ b/tools/perf/util/Build
@@ -150,7 +150,7 @@ CFLAGS_libstring.o += -Wno-unused-parameter -DETC_PERFCONFIG="BUILD_STR($(ET
CFLAGS_hweight.o += -Wno-unused-parameter -DETC_PERFCONFIG="BUILD_STR($(ETC_PERFCONFIG_SQ))"
CFLAGS_parse-events.o += -Wno-redundant-decls
-$(OUTPUT)util/syscalltbl.o: util/syscalltbl.c arch/x86/entry/syscalls/syscall_64.tbl $(OUTPUT)arch/x86/include/generated/asm/syscalls_64.c FORCE
+$(OUTPUT)util/syscalltbl.o: util/syscalltbl.c FORCE
$(call rule_mkdir)
$(call if_changed_dep,cc_o_c)
--------------------------------------------
Now trying to figure out how to, just for x86 to add a dep for those
files, but a arch specific thing shouldn't be in tools/perf/util/Build
anyway...
In the end I want this syscalltbl.c thing to know about all arches,
to remove the dependency on audit-libs as the way to map syscall ID to
name and vice-versa.
So I'll need all arches to generate that
arch/$(ARCH)/include/generated/asm/syscalls_64.c file, etc. Doing that
by copying from the kernel the files where such info is kept and having
a diff check as part of the perf build process, so that we can get
notified when it drifts while not tying tools/perf/ to anything outside
that can end up breaking the tools/ build when changes happen outside.

Jiri, I think this is enough, i.e. I think we make sure, just like the
kernel, that the archheaders target in tools/perf/arch/*/Makefile is
called before doing all the other build, no?
I.e. when we get to build syscalltbl.o the syscalls_64.c file will be
built already, limited testing seems to agree with this :-)

yep, having arch specific target in generic Build file is wrong
I'll have ppc64le available later today, I'll check on that

it looks ok, you can also now remove the whole syscalltbl.o override
and archheaders needs to be called before the build starts,
which is the case right now

perf build: Remove x86 references from arch-neutral Build
It will already be dealt with generating the syscalltbl.c file in the
x86 arch specific Build files, namely via 'archheaders'.
This fixes the build on !x86 arches, as reported for powerpcle
