Freebsd kernel compile
………………………..
compile kernel
1
編譯前檢查
檢查是否有完整的 FreeBSD source tree
2
產生並編輯新的kernel設定檔
#cd /usr/src/sys/amd64/conf
#cp GENERIC kernel2
#vi kernel2
編輯內容視需求修改
3
重建kernel後重開機
#cd /usr/src
#make buildkernel KERNCONF=kernel2
建立完後會出現完成訊息
————————————————————–
>>> Kernel build for kernel2 completed on Fri Nov 23 17:08:10 CST 2012
————————————————————–
#make installkernel KERNCONF=kernel2
#reboot
4
檢查是否編輯完成
#uname -a
FreeBSD systw 9.0-RELEASE FreeBSD 9.0-RELEASE #0: Fri Nov 23 16:58:02 CST 2012 root@systw:/usr/obj/usr/src/sys/kernel2 amd64
訊息出現kernel2,表示是使用新改的kernel開機
ps:
新的kernel會複製到 /boot/kernel/kernel
舊的kernel則移至 /boot/kernel.old/kernel
ps:
amd64是系統架構
其他架構還有
alpha
i386
pc98
sparc64
ps:
The kernel does not boot解決方案
1 在開機選擇中,選擇 Escape to a loader prompt
2 在prompt mode下輸入
unload kernel
boot /boot/kernel.old/kernel
ps:
列出各設備詳細資訊
pciconf -lv
ps:
pciconf — diagnostic utility for the PCI bus
SYNOPSIS
pciconf -l [-bcv]
pciconf -a selector
pciconf -r [-b | -h] selector addr[:addr2]
pciconf -w [-b | -h] selector addr value
