Hi all,
After merging the perf tree, today's linux-next build (native perf)
failed like this:

Caused by commit
f90a29144887 ("perf test: Remove C test wrapper for attr.py")
This is a native build of perf on ppc64le using
make -C tools/perf -f Makefile.perf NO_BPF_SKEL=1
I have merged the perf tree from next-20241010 for today.

Ok, thanks for the test. I'll drop the series and rebase the branch.

Is this a define issue? I dislike that PPC has a #define
__SANE_USERSPACE_TYPES__, we might be trying to fix something
inherently insane.
The failure at:
```
138 | snprintf(path, PATH_MAX, "%s/event-%d-%llu-%d", dir,
| ~~~^
| |
| long long
unsigned int
| %lu
139 | attr->type, attr->config, fd);
| ~~~~~~~~~~~~
| |
| __u64 {aka long unsigned int}
util/evsel.c:147:41: error: format '%llu' expects argument of type
'long long unsigned int',
but argument 4 has type '__u64' {aka 'long
unsigned int'} [-Werror=format=]
```
is for code moved from here:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/perf/tests/attr.c#n77
```
snprintf(path, PATH_MAX, "%s/event-%d-%llu-%d", dir,
attr->type, attr->config, fd);
```
ie the code is identical, so why does it compile in one file and not in another?
Elsewhere for PPC we carry:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/perf/tests/bp_account.c#n3
```
/*
* Powerpc needs __SANE_USERSPACE_TYPES__ before <linux/types.h> to select
* 'int-ll64.h' and avoid compile warnings when printing __u64 with %llu.
*/
#define __SANE_USERSPACE_TYPES__
```
Given the comment I suspect we need to do similar to fix this.
Stephen, could you test?
Thanks,
Ian

I added that to the start of tools/perf/util/evsel.c and it builds fine.
Thanks
