 Posted: Mon Dec 08, 2003 10:49 am Post subject: Ricompilazione kernel K7 |
 |
|
Nei miei vari esperimenti di ottimizzazione del kernel ho settato l'opzione specifica per K7 al posto della preimpostata generica 386... Al riavvio ho avuto molti errori nel caricamento dei moduli, del tipo
| Code: |
unresolved symbol _mmx...ecc
|
Riconducendo il termine mmx a processori intel, ho ricompilato rimettendo 386 e tutto è tornato a posto... c'è modo di risolvere il problema? |

prova a dare una pulitina al kernel prima di ricompilarlo
| Code: | # rm -rf /lib/modules/<tuokernel>
# cd /usr/src/linux
# cp .config ~
# make mrproper
# cp ~/.config .
# make oldconfig
# make dep && make clean bzImage modules modules_install |

ripulisce in modo accurato tutte le directory dei sorgenti del kernel. Cancella, se non vado errato, anche il file .config, facendoti partire da una configurazione mooolto di default.
avvia una configurazione automatica mettendo tutto in defualt (o sbaglio?)

in parole povere "make mrproper" ti ripulisce il kernel e te lo fa tornare come se l'avessi appena scompattato, solo che questa operazione ti porta a cancellarti pure il .config
il "make oldconfig" ti evita di dover aprire l'interfaccia grafica (make menuconfig) e poi uscire salvando...
penso comunque che le guide relative al kernel compiling possano dare un po' + di spiegazioni
spero cmq di esserti stato d'aiuto

Ho trovato questo sul forunm:
| Quote: |
Note that 'make mrproper' will remove the .config file -- if you've got a config you want to keep, back it up first, outside /usr/src/linux. And yes, 'make mrproper' includes all that would be done by 'make clean', plus more. It essentially leaves your source tree just like it was when it was first untarred.
As for menuconfig vs. xconfig, menuconfig is fine for me; I wouldn't say it's dreadful at all, though this likely is a matter of taste, and depend on whether you'd rather point and click, or use a terminal or console. Besides, of course, the obvious: you don't need X installed to use menuconfig.
One more note: 'make oldconfig' is also handy, if you've got an older "known good" .config file around, one from an earlier incarnation of the same kernel version, or one from an earlier version of the kernel (e.g., if you're going from 2.4.20 to 2.4.22). Put the old .config in a fresh /usr/src/linux, and 'make oldconfig'; you'll be prompted only for items that have changed or been added since that earlier kernel version. So, after backing up .config, you can make mrproper, oldconfig, dep, then the rest. Should work. |
Io devo cambiare l'opzione relativa al k7 perciò dopo il make mproper e avere riristinato il backup del .config, lancio make menuconfig, cambio l'ozione relativa al k7 e lancio la compilazione...right? |

si, immagino tu ti riferisca al "Processor Type" nel menu del kernel, quindi si
(pensavo ti riferissi semplicemenete a delle flag di compilazione)

Sara' che devi ricompilare anche i moduli (make modules) e installarli (make modules_install) e non solo ricompilare il kernel (make bzImage) ?

Penso proprio di no visto che e' una gif ed e' protetta da brevetto.

Ok, ho risolto eseguendo i seguenti passi:
| Code: |
# rm -rf /lib/modules/<tuokernel>
# cd /usr/src/linux
# cp .config ~
# make mrproper
# cp ~/.config .
# make menuconfig
attivata l'opzione relativa al k7
# make dep && make clean bzImage modules modules_install

forse ho detto delle bagianate (erano voci che ho preso per notizie...). Mi scuso, comunque questo è link. Entro un anno, se non ci sono state rinunce anticipate sui diritti, dovrebbe diventare tutto free.

Non ricordo nemmeno dove l'ho presa... è stato un lungo weekend di studio...
Eppoi quando uno non ricorda la proveniente il copyright non vale vero?
Se è per il formato ho il Gimp che converte
Cmq sta meglio in signature perchè come avatar ci si aspetta una cosetta diversa da uno smiley!
