> flushing 32MB of cache on every fork and exec? :/
That's what I was thinking, although the actual situation may be worse.
It appears we may flush the entire cache (32MB I-cache and 32MB D-cache)
on every cpu.
static void cacheflush_h_tmp_function(void *dummy)
{
flush_cache_all_local();
}
void flush_cache_all(void)
{
on_each_cpu(cacheflush_h_tmp_function, NULL, 1, 1);
}
void flush_cache_mm(struct mm_struct *mm)
{
#ifdef CONFIG_SMP
flush_cache_all();
#else
flush_cache_all_local();
#endif
}
