Mar 8, 1999 frc7v-cl1: Server Solaris 2.6、cc ドライバのテスト --- クライアントシステム上での cc ドライバのデバッグ#01(その6） ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ (http://www-online.kek.jp/~inoue/CAMAC/onl8v1-sol2.6-serv/ Cli1-CAMAC/debug-step06.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). 株式会社ロジックハウスの白田様より SPARC CPU-8VT と、VMEドライバ v2.3.1 を借用した。 (B). 株式会社ロジックハウスの白田様より Server Solaris 2.6 のシステム がインストールされているハードディスクを借用した。 (C). 借用したハードディスクのサーバ側のシステム設定を変更して、KEK の FP クラスタ上で立ち上げた。 (D). ファイルを直接修正する方法で、クライアント(その１)側のシステム 設定を変更したがクライアントは立ち上がれなかった。 (E). Solsticeを起動してホストマネージャを使って、frc7v-cl1ディスクレス クライアントの設定をやり直した。 (F). ディスクレス・クライアントのシステム、frc7v-cl1 が起動できること を確認した。 (G). frc7v-cl1 のシステムにVMEドライバ、FRCvme-2.3.1 をインストールし、 その後、frc7v-cl1 のシステム設定をやり直した。 (H). Solsticeを起動してホストマネージャを使って、frc7v-cl2ディスクレス クライアントの設定をやり直した。 (I). ディスクレス・クライアントのシステム、frc7v-cl2 が起動できること を確認した。 (J). frc7v-cl1、クライアントのシステムに ccドライバをインストールした。 (K). frc7v-cl1、クライアントのシステム上でサンプル・プログラムを実行 シングルアクションの 24ビットread/write は ok. LAM割り込み処理は、ok. ブロック転送 read/write は NG. (L). CPU-7Vのボードで FRCvme2.3.1 が正しく動作できることを確認した。 (M). frc8vt、サーバ・システムに ccドライバをインストールした。 (N). frc8vt、サーバ・システム上でンプル・プログラムを実行 シングルアクションの 24ビットread/write は ok. LAM割り込み処理は、ok. ブロック転送 read/write は 16 および 24ビットとも、ok. (O). 株式会社ロジックハウスの高橋様の修正された ccドライバを実行したが 状況に変化はなかった。 (P). 株式会社ロジックハウスの白田様の提案より、デスクレス・クライアント のシステムにローカル・ディスクをつなぎ、マウントした後で ccドライバ を実行したが状況に変化はなかった。 (Q). cam2 プログラムを実行すると、 cc.cプログラム中のどの命令を実行 した時にパニックを起こすのか調べた。 (R). 株式会社ロジックハウスの高橋様の提案より、savecore について調べる。 savecoreコマンドにより、vmcore.x および unix.x ファイルを入手した。 (S). ドライバ・プログラムが DMA完了の待ち状態のままになっているのを 　　　　　 確認 (2). ここでやるべきこと 正常に cam2プログラムが実行できている、frc8vt、サーバシステム上で トレースして、frc7v-cl1 での実行と比べて調べる。 (3). frc7v-cl1 上での実行再確認 割り込み処理ルーチンにトレースのための文を追加してから、実行を再確認 する。　 ロジックハウスの高橋さんからのメール。 >なぜcc_intr()ルーチンが実行されないのでしょう。 >おそらく、DMA転送が終了しないか、DMAが開始されていないなどの理由で >割り込みが発生しないなどの原因ではないでしょうか？ >正常に動作するシステムにてデバッグの表示をさせて比較を取ってみては >如何でしょうか? (3-1). まず、frc7v-cl1上での割り込み処理をトレースする (3-1-1). cc.c を編集、トレース用の文を付加する frc7v-cl1[42]% vi cc.c : static int cc_strategy(struct buf *bp) { register struct cc_device *cc = &ccdevice[0]; register struct K_REG
