loborisさんがリリースしている、Fedora22 のMinimal がどんなものテスト。
以下、備忘録です。Cで、GPIO ピンで光らせる部分まで確認。
・Fedora22_Minimal.img をsdcard に dd。要注意で。
$ sudo dd bs=1m if=./Fedora22_Minimal.img of=/dev/rdisk3
・BOOT パーティションの中は、orange pi pc の用途にあったものにリネーム。
[junkhack@OrangePi ~]$ ll /media/boot/ 合計 10695 -rwxr-xr-x 1 root root 35724 10月 13 14:08 script.bin -rwxr-xr-x 1 root root 10915616 10月 13 14:08 uImage
・SDCard 挿入、起動
・DHCP で起動するので、IP を固定に。以下のようになじみのあるeth0 に名前変更。
[root@opi 13:35:56 network-scripts]# ll ifcfg-* -rw-r--r-- 1 root root 364 Jan 1 1970 ifcfg-LoBoInternet -rw-r--r-- 1 root root 389 Dec 19 13:15 ifcfg-eth0 -rw-r--r-- 1 root root 254 Apr 9 2015 ifcfg-lo [root@opi 13:36:06 network-scripts]#
・中を変更
[root@opi 13:36:07 network-scripts]# cat ifcfg-eth0 TYPE=Ethernet BOOTPROTO=static DEFROUTE=yes PEERDNS=yes PEERROUTES=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_PEERDNS=yes IPV6_PEERROUTES=yes IPV6_FAILURE_FATAL=no NAME=eth0 UUID=c0a09f2a-3229-4901-9689-7deb7e356848 DEVICE=eth0 ONBOOT=yes DOMAIN=junkhack IPADDR=192.168.1.42 NETMASK=255.255.255.0 GATEWAY=192.168.1.1 DNS1=192.168.1.17 DNS2=192.168.1.1 [root@opi 13:36:23 network-scripts]#
・root のプロンプトを変更。好みで。
[root@opi 13:35:08 ~]# tail -n 3 .bash_profile PS1="[\u@opi \t \W]# " export LANG=C [root@opi 13:35:16 ~]#
・タイムゾーン設定
[root@opi 13:34:18 ~]# timedatectl set-timezone Asia/Tokyo
・後方の空きパーティション拡大。スクリプトが同梱されているので。ない場合は、git にあるので参照。
[root@opi 13:37:46 ~]# find / -name fs_resize /usr/local/bin/fs_resize [root@opi 13:37:59 ~]# [root@opi 13:39:25 ~]# fs_resize
リブート
・cpu周波数のツールを入れ、ポリシーを見てみる。interactiveのようです。
[root@opi 13:43:15 ~]# dnf install cpufrequtils
[root@opi 13:51:19 ~]# cpupower frequency-info
analyzing CPU 0:
driver: cpufreq-sunxi
CPUs which run at the same hardware frequency: 0 1 2 3
CPUs which need to have their frequency coordinated by software: 0 1 2 3
maximum transition latency: 2.00 ms.
hardware limits: 480 MHz - 1.54 GHz
available cpufreq governors: conservative, ondemand, userspace, powersave, interactive, performance
current policy: frequency should be within 480 MHz and 1.54 GHz.
The governor "interactive"★ may decide which speed to use
within this range.
current CPU frequency is 480 MHz (asserted by call to hardware).
cpufreq stats: 60.0 MHz:0.00%, 120 MHz:0.00%, 240 MHz:0.00%, 312 MHz:0.00%, 408 MHz:0.00%, 480 MHz:96.37%, 504 MHz:0.00%, 600 MHz:0.00%, 648 MHz:0.00%, 720 MHz:0.00%, 816 MHz:0.01%, 912 MHz:0.00%, 1.01 GHz:0.95%, 1.10 GHz:0.06%, 1.20 GHz:0.21%, 1.34 GHz:0.17%, 1.44 GHz:0.01%, 1.54 GHz:2.21% (173)
[root@opi 13:51:22 ~]#

http://oneofis05users.seesaa.net/article/288446337.html■ Interactive
より速いondemandを、ということで考案された。CPUがアイドル状態から
抜けるとサンプリングを増やして追従を上げる。反応はondemandより良いが、
最大クロックに上げるまでには間を取る。マルチタスクで忙しい仕事とゆっくり
した仕事が交互にあっても、最大最小に切り替え時に一気に上下せず少し間を取って、
中間のクロックを取る。パフォーマンス的にはondemandより良い。
画面オンで早くトップスピードに上げるので、画面オンの時間が短く、それを
繰り返すような使用法ではバッテリー消費が多くなる。
・kernel をあげてみる。上げる前は以下。

[Compile] pins.c
[Link]
[Install]
All Done.
NOTE: To compile programs with wiringBP v2, you need to add:
-lwiringPi
to your compile line(s) To use the Gertboard, MaxDetect, etc.
code (the devLib), you need to also add:
-lwiringPiDev
to your compile line(s).
