This is a very good point, but I think there are much bigger
problems then this to get NT loading on a ROM.
So that's an argument to introduce code which brings us further from the
goal?
This routine is pretty new and that's why it's
not called,
but from what I've read on SSE, prefetching is supposed to be
an ultra-time critical operation
Then inside the kernel it should be inlined, saves a CALL and RET. For use
by drivers it should be declared as __attribute__((dllimport)) in the
headers, saves a JMP. That is, if I buy the "ultra-time critical operation"
which I still do not, without any timing evidence.
When I studied the routine under Windows and I saw
that a
team of over 2 500 hardware and software experts with access
to gigantic user bases, profiling equipment and connections
with developers and Intel made the same decision, it was
gratifying.
How can we claim that ReactOS is an independent implementation when we start
to use "well, I reverse engineered Windows and Microsoft does it the same
way" as a implementation decision rationale? For that matter, why spent time
on ReactOS at all? Obviously, Microsoft with its huge teams knows better
anyway, so we should just stick to Windows.
