Apr 13, 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22） ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ (http://www-online.kek.jp/~inoue/CAMAC/onl8v1-sol2.6-serv/ Cli1-CAMAC/debug-step22.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 (T). cam2プログラムを frc8vt、frc7v-cl1上で実行して結果を調べた。 　　　frc8vt上での実行: (1). cv_wait_sig()コールが入っていると、そこで待ち状態が続く。 (2). cv_wait_sig()コールが入っていないと、正常終了する。 　　　frc7v-cl1上での実行: (1). cv_wait_sig()コールが入っていると、そこで待ち状態が続く。 (U). cv_wait_sig() を while文でループさせることで、シグナルを受け取れた (V). DMA 開始前に以前の割り込み信号が残って影響を与えていないことを 確認した。 (W). バーチャル・アドレス・スペースの割り当てを追加して動作させてみたが 症状は変わらない。 (X). cc->bp へのアクセスを camac_b()ルーチンでやらないようにしてみたが 症状は変わらない。 (Y). Soft State Managementルーチンを使ってみたが症状は変わらない。 (Z). minphys のバッファサイズを大きくして試してみたが症状は変わらない。 (2-A). camac_b（）を呼び出す箇所で渡す値をチェックしたが症状は変わらない。 (2-B). クラッシュダンプのチェック。 physio()でエラー。 (2-C). cc_strategy()ルーチンをチェック。 physio()でエラー。 (2-D). cc_strategy()ルーチンのcv_wait() を mutexロックした。変化なし。 (2-E). クラッシュダンプのチェック。　camac_b+0x2d0アドレスでエラー。 0xf60b5080?i camac_b+0x2d0: ld [%l0], %l1 $q (2-F). cc_device構造体へ cc_sys_statusを付加して調べた。 変化なし。 (2-G). cc->cc_sys_status = bp->b_error;　の行をcc_intr()ルーチンへ持って いって動作させた。 ok. cam2、camacブロック転送は正常に実行できた。 (2-H). デバッグ用に付加した部分で実行上必要のない文を削除した。cam3実行 でタイムアウト時にシステムクラッシュが起きた。 (2). ここでやるべきこと cam3のデバッグをやる。 状況確認。 (3). cam3実行時にタイムアウトでシステムクラッシュを起こす状況を確認 cam3、camac割り込み処理を実行する。 frc7v-cl1[61]% cam3 *** Now waiting LAM ...

LAM を待つ。 4. LAM割り込みが発生したら、LAMソースをクリアする。 5. タイムアウトタイム内にLAM割り込みが発生しなかったら タイムアウト処理を行う。 6. 指定回数だけ LAM処理が実行されたら、camacコントローラに対して LAMディセーブルを実行。 の部分がポイントになる。 この内、項目 1 と 4 は camacシングルアクション動作である。 これについて は正常に動作するのを確認しているので、ここでは調査の対象からはずす。 項目 2、3 および 5 を中心に調べる。 1. CAM_EnableLAM(mask) 2. CAM_WaitLAM(timeo) 3. printf("Timeout !! count=%d\n", i + 1); CAM_EnableLAM()ルーチンが実行していることを調べる。 frc7v-cl1[57]% pwd /export/home/frc7v-cl1/inoue/CAMAC/Driver/FORCE-5V-sol2.5 frc7v-cl1[58]% ls Makefile camlib.o cc_common.h README cc cc_config.h cam1* cc.c forlib.c cam1.c cc.c-Apr-7-1999-ok forlib.o cam2* cc.c-bak/ k2917.h cam2.f cc.c-org ktaka/ cam2.nm cc.conf libcamac.a cam3* cc.h out cam3.c cc.h-Apr-5-1999 out1 camlib.c cc.h-org out2 camlib.h cc.new.c* script/ frc7v-cl1[59]% grep CAM_EnableLAM * cam3.c: status += CAM_EnableLAM(mask);

ほとんどのデバイス・ドライバは、コントロールするデバイスの各インスタンス 毎にステート情報を保持している; たとえば、デバイス・コントロール レジスタのソフトコピー、ハードウェアのひとつにアクセスしている間中 保持しなければならない mutex、パーティション・テーブル、あるいは unit構造などである。　これらのユティリティ・ルーチンは、そのような state情報を保持することで、ドライバによって使われるスペースをデバイス ドライバが管理することを意図している。　たとえば、ドライバがひとつの state構造の中に各インスタンスのstateを保持するならば、インスタンスが アタッチ、ディアタッチされることで、これらのルーチンはドライバの 各インスタンス用の別々の構造体をダイナミックにアロケート、ディアロケート するために使うことができる。 ルーチンを使うために、ドライバを書く人は stateポインタを宣言することが 必要である。　state_p はドライブ構造毎にセットでハングする場所で使う。 すべてのものはこのルーチンが管理する。 ddi_soft_state_init() は stateポインタをイニシャライズするために、 あるいは soft state構造体のサイズをセットするために、さらに必要ならば ドライバがそのような構造体に前もって数を割り当てることを許すために、 通常はドライバの _init(9E)ルーチンの中でコールされる。 ddi_soft_state_zalloc() はドライバの attach(9E)ルーチンの中で通常は コールされる。 ルーチンは itemナンバを渡される。　 getminor() について 高橋さんからのメール ---ここから
