Sort of (the patch has the intended effect, but for its size very
many rough edges).
I guess we need to amend the original parameter, once_mapping_mfns, like
this,
/* xen_once_mapping_mfns: memory mapping mfn bumbers once. */
unsigned int xen_once_mapping_mfns;
size_param("once_mapping_mfns", xen_once_mapping_mfns);
static void xen_once_mapping_mfns_setup(void)
{
if ( once_mapping_mfns < 64 )
xen_once_mapping_mfns = 64;
else if ( once_mapping_mfns > 1024 )
xen_once_mapping_mfns = 1024;
else
xen_once_mapping_mfns = once_mapping_mfns;
}
Or what is your expected rule?
Thanks
Tiejun
