Aug 1, 2000 onl50t: Solaris 2.6 cc ドライバのデバッグ. cc ドライバのデバッグ#04(その6） ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ (http://www-online.kek.jp/~inoue/CAMAC/ onl50t-sol2.6/Desktop/debug-list-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-50T を借用した。 (B). FORCE,CPU-50(UltraSPARC-IIi 300MHz)、に Solaris2.6 のシステムを インストールした。 (C). /etc の下の各設定、および /export/home の作成をやった。 (D). "Solaris2.6 Hardware: 5/98 SMCC Desktop 日本語版 SPARC版"では ディスクレス・クライアントを設定することはできないことを確認した。 (E). CPU-50T に Solaris2.6用の VMEドライバ、FRCvme-2.3.1 をインストール した。 (F). onl50t に ccドライバをインストールした。 (G). サンプル・プログラムを実行した。 (1). cam1、シングル・アクション 24ビット camac read/write の実行 NG. システムはパニックを起こしてリブートしてしまう。 (2). cam3、camac LAM割り込み処理の実行 NG. システムはパニックを起こしてリブートしてしまう。 (3). cam2、ブロック転送 16ビット read/write の実行 ok. 正常に実行できた。 (4). cam2、ブロック転送 24ビット read/write の実行 ok. 正常に実行できた。 (H). クラッシュ時の savecoreファイルを入手してデバッグを始めた。 (I). cam1プログラムのデバッグ、icc_ioctlルーチンを修正した。 ok. cam1プログラムは正常に実行できた。 (J). cam3プログラムのデバッグを始めた。 camac_s()ルーチンの中で "cc->k->dhr = *dat;" を実行したところでエラーになっている。 message構造体をcc_device構造体の中に入れてみたが改善されない。 (K). cam3プログラムは正常に動作できるようになった。 (L). cam3プログラムのデバッグ時に付加したゴミをはずして最終的な動作確認 をやった。 ok. (M). onl50t 上でデバッグしたcamacドライバをfrc7v-cl2 上で動作確認した。 ok. (N). onl50t 上でデバッグしたcamacドライバを onl7v2、スタンドアロン Solaris2.6 上で動作確認した。 ok. (O). onl50t 上でデバッグしたcamacドライバを frc8vt、ディスクレス・サーバ Solaris2.6 上で動作確認した。 ok. (P). onl50t 上でデバッグしたcamacドライバを onl8v1、スタンドアロン Solaris2.6 上で動作確認した。 ok. (Q). onl50t 上でデバッグしたcamacドライバを onl5v4、スタンドアロン Solaris2.6 上で動作確認した。 ok. (R). スタンドアロン Solaris2.6、onl50t 上で、シングルアクションの実行 速度を測定時に、camac_s()コールを連続実行すると不正割り込みが かかってしまった。 (S). camac_s()コールを連続実行しても不正割り込みはかからないように なった。 ok. -------------------- リスト処理 (A). 公開版のcamacドライバ、"FORCE-50T-sol2.6" を使ってリスト処理の テストを始める。 (B). KEKリスト処理で camacシングルアクション read/write、LAM割り込み 処理、DMA camacブロック転送の現状確認をした。 (C). Kineticリスト処理で camacシングルアクション read の現状確認をした。 (D). KEKリスト処理、Kineticリスト処理両方をとおしてソースプログラム上で 明らかに問題と思われる部分を修正した。 (E). KEKリスト処理でシングルアクション read/write が正常に実行できて いることを確認した。 (F). KEKリスト処理で DMA camacブロック転送 read が正常に実行できて いることを確認した。 (2). ここでやるべきこと KEKリスト処理で LAM割り込み処理が正常に実行できるようにする。 (3). 現状確認 (3-1). オリジナルの camtest4int.asm による実行 onl50t[185]% pwd /export/home/onl50t/inoue/CAMAC/Driver/Kit-test/CAMAC-list/FORCE-50T-sol2.6/camlist onl50t[186]% cat camtest4int.asm ;

ARGUMENTS func Kernel function to invoke when the time increment expires. arg Argument to the function. ticks Number of clock ticks to wait before the function is called. DESCRIPTION The timeout() function schedules the specified function to be called after a specified time interval. The exact time interval over which the timeout takes effect cannot be guaranteed, but the value given is a close approximation. The function called by timeout() must adhere to the same restrictions as a driver soft interrupt handler. The timeout() function returns an identifier that may be passed to the untimeout(9F) function to cancel a pending request. timeout() can be called from user or interrupt context. The function called by timeout() is run in interrupt context and must not sleep or call other functions which may sleep. RETURN VALUES Under normal conditions, timeout() returns an integer timeout identifier not equal to zero. If, however, the timeout table is full, the system will panic with the fol- lowing panic message: PANIC: Timeout table overflow CONTEXT timeout() can be called from user or interrupt context.
