Hi Stephane,
I've tried out this kernel patch and ran into a minor error. There's a
config option under Hardware Performance Monitoring support called "Enable
perfmon statistics reporting via debugfs"
If I turn this on, I get a link-time error, because of the following lines
in perfmon/perfmon_priv.h
#ifdef CONFIG_PERFMON_DEBUG_FS
int prfm_init_debugfs(void);
#else
static inline int pfm_init_debugfs(void)
{
return 0;
}
#endif
Should the config option be removed so that it can't be enabled (for now) ?
