*libata試行メモ [#k0fffe1b]
landisk、usl-5p共にとりあえず動きました。。~
以下そのメモです。
-linux-2.6.21-rc2の差分パッチ -- &ref(linux-2.6.21-rc2-landisk.patch);~
--主要変更点
---arch/sh/boards/landisk/Makefile
---arch/sh/boards/landisk/irq2.c
---arch/sh/boards/landisk/landisk_drv.c
---arch/sh/boards/landisk/psw.c
---arch/sh/boards/landisk/setup2.c
---arch/sh/configs/landisk_defconfig-ata
---drivers/rtc/rtc-rs5c313.c
~
-kernelバイナリ/モジュール -- LANDISK & USL-5P 両対応
-- &ref(zImage-2.6.21-rc2-landisk.tgz);~
-- &ref(lib-2.6.21-rc2-landisk.tgz);~
-landisk-tools
--btnctrl3 … push-switchインタフェース対応
--&ref(landisk-tools-20070307.tgz);~
-.config
--&ref(landisk_defconfig-ata.txt);
-kexecを使ったブートの例~
#pre{{
# kexec --append="mem=64M console=ttySC1,9600 &color(red){root=/dev/sda3};" zImage-2.6.21-rc4-landisk
}}
-libataを使ってみての注意点等
--従来/dev/hda[123]で参照していた箇所が全て/dev/sda[123]へ変わります。/etc/fstab、/etc/lilo.conf 等がその該当箇所です。
--USBストレージのデバイスの割り当てが /dev/sda -> /dev/sdb 等へ変わってしまうかもしれません。
