まるしすなうぇぶろぐ(仮): 玄柴/ディスプレイの接続で 紹介いただいている手順を LinkStation LS-VL で検証しようとして、いきなりつまづいた。

CONFIG_FB_CFB_IMAGEBLIT を m に

デフォルトは、Kconfig にかいてあるようなので、 Kconfig を書き換える。こんなんでええの?

yasunari@vl:/mnt/src/linux-2.6.31.8$ cd drivers/video/
yasunari@vl:/mnt/src/linux-2.6.31.8/drivers/video$ mv Kconfig{,.orig}

できた! \^_^/

Makefile の修正

ちょっと寄り道してMakefile を修正。
make modules_install で /lib/modules にコピーされるように。
