I have downloaded linux-next and build the perf tool using
# make LIBPFM4=1
to have libpfm4 support built into perf. The build fails:
# make LIBPFM4=1
....
INSTALL libbpf_headers
CC util/pfm.o
util/pfm.c: In function ‘print_libpfm_event’:
util/pfm.c:189:9: error: too many arguments to function ‘print_cb->print_event’
189 | print_cb->print_event(print_state,
| ^~~~~~~~
util/pfm.c:220:25: error: too many arguments to function ‘print_cb->print_event’
220 | print_cb->print_event(print_state,
The build error is caused by commit d9dc8874d6 ("perf pmu-events:
Remove now unused event and metric variables") which changes the
function prototype of
struct print_callbacks {
...
void (*print_event)(...); --> last two parameters removed.
};
but does not adjust the usage of this function prototype in util/pfm.c.
In file util/pfm.c function print_event() is still invoked with 13
parameters instead of 11. The compile fails.
When I adjust the file util/pfm.c as in this patch, the build works file.
Please check this patch for correctness, I have just fixed the compile
issue.
Fixes: d9dc8874d6 ("perf pmu-events: Remove now unused event and metric variables")
