 |
|
Ciao; la mia domanda per molti è sicuramente "banale" ; attualmente sto usando Gentoo senza initramfs sfruttando come base un kernel-config di un mio conoscente.
Purtroppo però, non riesco a capire dove diavolo mettere le cose come "built in" se per esempio dovessi compilare Gentoo su altro computer quindi con caratteristiche hardware diverse.
Poco fa ho messo tutto il possibile riguardo SCSI drivers come built-in ma ... kernel panic ovvero non partiva.
Chiedo umilmente se potete darmi "ragguagli" su come "operare" in modo "metodico".
Grazie ^^

Solitamente senza initramfs devi aggiungere built i vari controller e soprattutto il driver per il file system che usi.
Posta l'errore che ti da e anche l'output di lspci -v

Usando un differente .config da me creato:
All'avvio kernel panic dovuto appunto a "qualcosa" che non è "built-in" e che mi sfugge.
Attualmente sto usando un kernel config che funziona senza initramfs .... appunto "elaborato su una base che mi è stata data da un Gentooista che provai e funziona.
Però il mio è stato un "copiare" senza "consapevolezza" riguardo il perchè funziona.
Se tento io ... tentando di costruire ex-novo un config-file per kernel, qualcosa mi sfugge ed ottengo errore. Purtroppo non riesco da solo a capire cosa.
Scusa la mia ignoranza

Scusa doppio post .....
Forse ho capito :
| Code: |
ci74771ht ~ # zgrep -i ahci /proc/config.gz
CONFIG_SATA_AHCI=y
CONFIG_SATA_AHCI_PLATFORM=y
# CONFIG_AHCI_CEVA is not set
# CONFIG_AHCI_QORIQ is not set
# CONFIG_SATA_ACARD_AHCI is not set
|
E' quello che funziona;
| Code: |
ci74771ht ~ # grep -i ahci /home/cst_config
CONFIG_SATA_AHCI=m
# CONFIG_SATA_AHCI_PLATFORM is not set
CONFIG_SATA_ACARD_AHCI=m
ci74771ht ~ #
|
Questo quello che non funziona.
Può davvero essere colpa di questa imp'ostazione il risultato dei miei fallimenti ?

Piu' che possibile se hai un controller sata.

No ... non è solo quello 
Purtroppo non riesco a risolvere l'arzigogolo
fare un diff fra configurazioni differenti è un "macello".
Attualmente son con questo kernel:
| Code: |
$ uname -a
Linux ci74771ht 4.9.76-gentoo-r1 #1 SMP PREEMPT Tue Apr 3 23:21:40 CEST 2018 x86_64 Intel(R) Core(TM) i7-4771 CPU @ 3.50GHz GenuineIntel GNU/Linux
|
Che funziona bene (e senza initramfs).
Ora scarico le vanilla-sources-4.15.15, quindi con il ".config" di default (che non riesce a partire da solo senza l'ausilio di initramfs).
Non tocco nulla; cosa dovrei fare/guardare/controllare/modificare per far si che esso non debba aver necessità di initramfs ?
Scusate se sono una "seccatuira"

Mi correggo ... ho già cominciato ad inserire qualcosa come "built-in" ... ma il risultato è sempre un "panic":
immagine2
kernel-config (vanilla 4.15.15)
Se c'è un aiuto Grazie infinite.

Puoi anche postare la configurazione delle tue partizioni (il tuo /etc/fstab)?

Certamente

Ok ... la "manna" mi è arrivata dal "cielo" ^^
Ho provato sia partendo dalla mia distro in chroot che partendo dal livecd "gentoo minimal" ... e funziona ^^^^^^^^^^^^^^^^^ 
| Code: |
# make localyesconfig
|
è stato risolutivo ^^
PS: davvero gran bella utility ^^
