Sep 24,1998 pollux: Solaris 2.6 cc ドライバのテスト. Solaris2.6 システムのインストール --- VMEドライバのインストール#03 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ (http://www-online.kek.jp/~inoue/CAMAC/ pollux-sol2.6/vme-step01.txt) 高エネルギー加速器研究機構 素粒子原子核研究所 物理、オンライングループ 井上 栄二 (1). 現状確認 (A). 物構研、金谷さんの SPARC CPU-7V の camac システムが動作しない とのこと。 1. camacシングルアクションread/write は正しく実行できる。 2. camac割り込み処理はうまく実行できない。 3. camac DMA read/write はうまく実行できない。 (B). CPUボード、K2917ボード、K3922ボードは正しく動作していることを 確認した。 K2917 は私が使用しているものとは仕様が異なっていたので cc.c を修正して正しく動作するのを確認した。 (C). 上記の(B)で動作確認した CPUボード、K2917ボード、K3922ボードに、 金谷さん所有のシステム・ディスクをつないでサンプル・プログラムを 実行した。 cam1、cam3、cam2 の全て NG。 (D). 金谷さんのシステム・ディスクに英語版 Solaris2.6 をインストール し直した。 (E). /etc の下の各設定、および /export/home の作成をやった。 (2). ここでやるべきこと 7V に Solaris2.6用の VMEドライバ、FRCvme-2.2.2 をインストールする。 (3). FRCvme をインストールする (3-1). pkginfo を実行して、現在インストールされているFRCvme をチェック。 onl7v2# pkginfo -l FRCvme ERROR: information for "FRCvme" was not found onl7v2# onl7v2# df -k Filesystem kbytes used avail capacity Mounted on /dev/dsk/c0t3d0s0 38799 15601 23160 41% / /dev/dsk/c0t3d0s6 586735 383722 202427 66% /usr /proc 0 0 0 0% /proc fd 0 0 0 0% /dev/fd /dev/dsk/c0t3d0s1 25271 4561 20685 19% /var /dev/dsk/c0t3d0s7 7842917 36372 7728116 1% /export/home /dev/dsk/c0t3d0s5 28719 10049 18642 36% /opt swap 239392 16 239376 1% /tmp /vol/dev/dsk/c0t6d0/frcvme 19456 19456 0 100% /cdrom/frcvme kiwifs:/public/sun/Solaris2 8316189 7572713 660315 92% /kekfs/kek onlsun1:/home1/local 1572360 1395728 175064 89% /net/onlsun1/home1/local onlsun1:/home1/cern/95a 1572360 1395728 175064 89% /net/onlsun1/home1/cern/9 5a onl7v2# (3-2). pkgadd を実行して、FRCvme をインストールする。 onl7v2# pkgadd -d /cdrom/frcvme/pkg The following packages are available: 1 FRCctrl sysconfig driver SPARC/CPU-3CE,5CE,5TE,5V,7V,8V,20V,24V (sparc.force) V1.1 2 FRCvme VMEbus Driver CPU-3CE,5CE,5TE,5V,7V,8V,20V,24V Solaris 2.5, 2.6 (sparc.force) V2.2.2 Select package(s) you wish to process (or 'all' to process all packages).
