Mar 11, 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7） ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ (http://www-online.kek.jp/~inoue/CAMAC/onl8v1-sol2.6-serv/ Cli1-CAMAC/debug-step07.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。 (2). ここでやるべきこと cc_intr() から cv_signal() をコールしているのにcv_wait_sig() が シグナルを受け取れないでいる件について調べる。 (3). cv_wait_sig() の再考察 現在の問題点の一つは、cc_intr() から cv_signal() をコールしているのに cv_wait_sig() がシグナルを受け取れないでいる点である。 cv_wait_sig() の実行をループさせてみる。 cc.cファイルを修正する。 frc7v-cl1[41]% pwd /export/home/frc7v-cl1/inoue/CAMAC/Driver/FORCE-5V-sol2.5 frc7v-cl1[42]% vi cc.c : static u_int cc_intr() { register struct cc_device *cc = &ccdevice[0]; register struct K_REG *k = cc->k; mutex_enter(&cc->mutex); /* start MUTEX */ /* E.Inoue: from */ cmn_err(CE_NOTE," cc_intr: debug step06. --- enter cc_intr()"); /* E.Inoue: end */ /* check K2917 register */ if ((k->csr & CC_LAM) != 0) cc->interrupt |= CC_INT_LAM; if ((k->csr & CC_DONE) != 0) cc->interrupt |= CC_INT_DONE; if ((k->empc & CC_INT_ENABLE) == 0) cc->interrupt |= CC_INT_EMPTY; if ((k->aboc & CC_INT_ENABLE) == 0) cc->interrupt |= CC_INT_ABORT; /* E.Inoue: from */ cmn_err(CE_NOTE," cc_intr: debug step06a. --- cc->interrupt=0x%x", cc->inter rupt); /* E.Inoue: end */ /* free DMA resources */ if (cc->executing_dma_flag != 0) { /* E.Inoue: from */ cmn_err(CE_NOTE," cc_intr: debug step06b. --- cc->executing_dma_flag != 0"); /* E.Inoue: end */ /* change logichouse */ /* ddi_dma_free(cc->handle); */ ddi_dma_unbind_handle(cc->handle); /* end */ biodone(cc->bp); cc->executing_dma_flag = 0; } if (cc->interrupt == 0) { /* reject interrupt, then return */ mutex_exit(&cc->mutex); /* end MUTEX */ /* E.Inoue: from */ cmn_err(CE_NOTE," cc_intr: debug step06c. --- reject interrupt: return cc_in tr()"); /* E.Inoue: end */ return DDI_INTR_UNCLAIMED; } else { /* accept interrupt, then wake up waiting process, then return */ untimeout(cc->timeout_id); cv_signal(&cc->cv); mutex_exit(&cc->mutex); /* end MUTEX */ /* E.Inoue: from */ cmn_err(CE_NOTE," cc_intr: debug step06d. --- accept interrupt: return cc_in tr()"); /* E.Inoue: end */ return DDI_INTR_CLAIMED; } } static int cc_strategy(struct buf *bp) { register struct cc_device *cc = &ccdevice[0]; register struct K_REG *k = cc->k; register u_long dma_addr; register mode = cc->mode; register naf = cc->naf; register int wc = (mode & CC_BIT16) ?
