 Posted: Tue Jul 19, 2005 10:03 am Post subject: MMX or not MMX, that's a question of mine |
 |
|
Is my system less than optimized?
I do have problems with playing media. This PIII/600MHz stumbles on stuff that my Win P133MHz handles ok. And this outcome is valid for not only this file or filetype.

MMX2 supported but disabled

I see "MMX supported but disabled". And I also see the flags. Should the USE variable contain 'mmx' (it doesn't now)? |

what does
| Code: | | # cat /proc/cpuinfo |
say?
| Quote: | CPUflags: MMX: 0 MMX2: 0 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 0

i think that are the flags with which mplayer is compiled atm.
look at cpuinfo and add the supportet flags to /etc/make.conf
then check with
| Code: | | # emerge -va --newuse world |
whats changed...

add "mmx" to your /etc/make.conf USE-Section.
recompile all stuff where it makes a sence...
| Code: | | # emerge -va --newuse world |
then check performance again...

Thanks I will.
A bit reluctant at this very point as I have some 100 packages left on a
But looking forward to try
This of course raises another question, perhaps not fitting in this part of the fora, but:
Will | Code: | | # emerge -va --newuse world |
modify only packages that need to be updated?
Off to read some man pages ... |

| Code: | | # emerge -va --newuse world |
will reemerge all packages for which the use flags have changed since last compile...
for all packages to update you have to type
| Code: | | # emerge -uDva world |

Thanks for all the aid. If it helped, it was marginal.
Seems like xorg was the only package that was affected by mmx

There is a MMX2 as well, but I can't see a USE variable by that name. How can I enable that? |

A small table of currently available use variables and a short description of each
^^^^<- I think thats why....
i simply use:
/usr/portage/profiles/use.desc
/usr/portage/profiles/use.local.desc
to search for USE-Flags and the descriptions...

Thanks very much for that clarification.
Seems only mplayer make use of mmxext in the whole world, but I have no time to recompile that at the moment. Back next week (I happen to be the project manager of www.amigbg.com).
Totem and Xine works pretty much the same as before |
