mt7610uをDKMSに / 2015-05-21 (木)

先日、mt7650u_staモジュールで [External] PLANEXのGW-450DとELECOMのWDC-433SU2MBKを動かす事に成功したので、mediatek_mt7610u_sta_driver_linux-64bitドライバをDKMS化しておく事に。

apt-getでdkmsパッケージをinstallした後、まずはmediatek_mt7610u_sta_driver_linux-64bitフォルダを/usr/src配下にコピー。

yano@T60:~$ sudo apt-get install dkms
yano@T60:~$ cp -pr ~/mediatek_mt7610u_sta_driver_linux-64bit /usr/src/mt7610u-20150318

次に、dkmsの設定ファイル/usr/src/mt7610u-20150318/dkms.confを作成します。

yano@T60:/usr/src$ sudo vi /usr/src/mt7610u-20150318/dkms.conf
PACKAGE_NAME="mt7610u"
PACKAGE_VERSION="20150318"
CLEAN="make clean"
MAKE[0]="make KERNELVER=${kernelver}"
BUILT_MODULE_LOCATION[0]="os/linux"
BUILT_MODULE_NAME[0]="mt7650u_sta"
DEST_MODULE_LOCATION[0]="/kernel/drivers/net/wireless"
AUTOINSTALL="yes"

続いてdkms.confで対象kernel版数を指定できるようMakefileの"$(shell uname -r)"を変数"$KERNELVER"に書き換え、

yano@T60:/usr/src$ diff -u ~/mediatek_mt7610u_sta_driver_linux-64bit/Makefile ./mt7610u-20150318/

最後にdkmsコマンドでadd/installすれば良い。

yano@T60:/usr/src$ sudo dkms add -m mt7610u -v 20150318
