My God.. I love this part: |
2 |
|
3 |
Ok, so I had some users complain about mmx2 being showed as enabled |
4 |
in mplayer despite the lack of mmxext in /proc/cpuinfo. Therefore I |
5 |
decided to get upstream help. Here's what we got...: |
6 |
|
7 |
mmx2 = sse |
8 |
sse = mmx2 |
9 |
|
10 |
but in mplayer's configure script: |
11 |
|
12 |
mmx2 = sse's integer logic |
13 |
sse = sse's floating point stuff |
14 |
|
15 |
so mmx2 is NOT a flag for mmx2 support.. it's a flag for integer portion |
16 |
of sse... |
17 |
|
18 |
ok, so at this point I'm confused as to how to approach this. What |
19 |
about AMD? Do they use mmxext for stuff like that.. or sse2 extensions |
20 |
(as someone mentioned). My plan is to have sse USE flag enable mmx2 |
21 |
only (since it's "the best") and disable sse (since it's the same thing |
22 |
but "worse"). However, that only takes care of intel.. what about AMD |
23 |
processors though? They deal with all this stuff differently. |
24 |
Recomendations are welcome at this point.. I'm going to get some asprin... |
