Guess, this is trivial question but probably useful to know.
void free_initmem(void)
{
#ifdef CONFIG_HAVE_TCM
extern char __tcm_start, __tcm_end;
totalram_pages += free_area(__phys_to_pfn(__pa(&__tcm_start)),
__phys_to_pfn(__pa(&__tcm_end)),
"TCM link");
#endif
#ifndef CONFIG_HOTPLUG_CPU
if (!machine_is_integrator() && !machine_is_cintegrator())
totalram_pages += free_area(__phys_to_pfn(__pa(__init_begin)),
__phys_to_pfn(__pa(__init_end)),
"init");
#endif
}
Here i don't see any printk information for specifying how much memory is freed.
Other architectures do have this printk e.g kernel/arch/ia64/mm/init.c +169
While checking this excellent answer[1] given by rene i found that arm
is missing this or may be i am missing something probably this information
i can find it somewhere else also.
Intention was to add __devinit in my probe function and out of
curiosity how much
i am saving.
