|
|
Hey all, just a quick question for ya.
I've just upgraded from an athlon TBird 1.3GHz to an Athlon XP 2500+(mobile), but am getting some funky errors ("failed to calculate module dependencies" is the killer). I was wondering, this being a system bootstrapped to --march=athlon-tbird, are there (backwards)compatability issues here? (i.e. --march=athlon-tbird not working properly on an XP)
Thanks everyone!

yes, you will have some issues since it wasnt installed with the -march=athlon-xp flag _________________ http://www.whatsinyourbox.org -- Technology discussion, news, and more. |

ok, cheers. Looks like i gotta wait until i'm back on the uni net before i get it sorted. (dialup at home sucks compared to a full speed 10Mbit/s line)

Erm, may I ask which instructions the TBird supports that the XP doesn't? I mean, you can compile everything with -march=i386 and it would run on anything that supports at least the i386 instruction set. Similarly, you should be able to compile something with -march=athlon-tbird and run it on an XP. If you did it the other way round, compiling for the XP and running on the TBird, you would obviously get into troubles since the XP is newer and supports more instructions (SSE comes to my mind, maybe others). The way he did it, though, shouldn't be a problem at all, apart from maybe not utilising all capabilities of the new processor (but you normally wouldn't notice that). Very strange... |

the thing is that when a new processor comes out, it doesnt just allow for new instructions, but it handles previously used ones differently _________________ http://www.whatsinyourbox.org -- Technology discussion, news, and more. |

justcompile your kernel, and remember to set the processor type to athlonxp, x(3,4,5,6)86. remember to make modules modules_install also. |

ok, update for y'all.
Setting RC_PARALLEL_STARTUP=yes has allowed my modules to load, even though it still fails on calculating the dependencies (shame...)
everything else *seems* to be perfectly functional, except i get LOTS of lines like:
Code: | modprobe: WARNING: /etc/modprobe.conf line 68: ignoring bad line starting with "unset" |
scrolling past on startup, then again on login, then again one, well, pretty much anything
Any ideas?
P.S. ut2k4 runs sweeeetly now |

documentation? I would love to read about this...
I mean if they were going to change 3dnow instruction set would it still be 3dnow?
the only thing that's different between the two procs is sse support in the xp right?? everything else is the same....
