FreeBSD-current/mipsが動いた
初めてマトモに起動してるところをみた。
以下、作業記録：
cvsupでcurrentをダウンロードしてくる。
supfileはこんな感じ：
*default host=cvsup.jp.FreeBSD.org *default base=/home/syuu/FreeBSD *default prefix=/home/syuu/FreeBSD/cvsroot *default release=cvs tag=. *default delete use-rel-suffix *default compress src-all
次が重要。
patchを当てなければならない。まだcurrentには全部のコードがマージされてないっぽいのだ。
cd /home/syuu/FreeBSD/cvsroot/src fetch http://people.freebsd.org/~imp/MipsSvn.diff patch -p0 < MipsSvn.diff
ビルドしてみる。今回はgxemulでmaltaをエミュレートしてみることにした。
export MAKEOBJDIRPREFIX=~/FreeBSD/cvsroot/src/obj sudo make WITHOUT_CDDL=1 TARGET_ARCH=mips buildworld sudo make WITHOUT_CDDL=1 TARGET_ARCH=mips KERNCONF=MALTA buildkernel
ディスクイメージを作成。
dd if=/dev/zero of=freebsd-mips.img count=1024 bs=1m sudo mdconfig -a -t vnode -f ./freebsd-mips.img sudo disklabel -w /dev/md0 sudo disklabel -e /dev/md0
aのunusedを4.2BSDに変更して保存。
sudo newfs /dev/md0a sudo mount /dev/md0a /mnt/
ディスクイメージにユーザランドを書き込み。
sudo make WITHOUT_CDDL=1 TARGET_ARCH=mips DESTDIR=/mnt/ installworld sudo umount /mnt
エミュレータを実行。
sudo gxemul -emalta -d freebsd-mips.img /usr/obj/mips/usr/home/asada/FreeBSD/cvsroot/src/sys/MALTA/kernel
何故かカーネルが/usr/obj/mipsにインストールされてしまった。どうして？
ともあれ、何とか起動してくる。

なんだこれ。
でもなんか動いてる。
