Well, DIAGNOSE 260 is z/VM only and DIAG 500 is KVM only. So there are
currently not really any other reasonable ways besides SCLP.
Correction: Staring at the code again, in detect_physmem_online_ranges()
we will indeed try:
a) sclp_early_read_storage_info()
b) diag260()
So why care to call diag260() in case of DIAGNOSE 500? What about the below?
void detect_physmem_online_ranges(unsigned long max_physmem_end)
{
if (!sclp_early_read_storage_info()) {
physmem_info.info_source = MEM_DETECT_SCLP_STOR_INFO;
} else if (physmem_info.info_source == MEM_DETECT_DIAG500_STOR_LIMIT) {
unsigned long online_end;
if (!sclp_early_get_memsize(&online_end)) {
physmem_info.info_source = MEM_DETECT_SCLP_READ_INFO;
add_physmem_online_range(0, online_end);
}
} else if (!diag260()) {
physmem_info.info_source = MEM_DETECT_DIAG260;
} else if (max_physmem_end) {
add_physmem_online_range(0, max_physmem_end);
}
}
Works for me, thanks!
