Jun 25, 1999 onl50t: Solaris 2.6 cc ドライバのデバッグ. cc ドライバのデバッグ#01(その4） ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ (http://www-online.kek.jp/~inoue/CAMAC/ onl50t-sol2.6/Desktop/debug-step04.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。 (2). ここでやるべきこと cam3プログラムのデバッグをする(その2)。 kmem_alloc()を使ってみる。 (3). kmem_alloc()の使用 Dynamic Memory Allocation Device drivers must be prepared to simultaneously handle all attached devices that they claim to drive. There should be no driver limit on the number of devices that the driver handles, and all per-device information must be dynamically allocated. void *kmem_alloc(size_t size, int flag); The standard kernel memory allocation routine is kmem_alloc(9F). It is similar to the C library routine malloc(3C), with the addition of the flag argument. The flag argument can be either KM_SLEEP or KM_NOSLEEP, indicating whether the caller is willing to block if the requested size is not available. If KM_NOSLEEP is set, and memory is not available, kmem_alloc(9F) returns NULL. kmem_zalloc(9F) is similar to kmem_alloc(9F), but also clears the contents of the allocated memory. ---------------------------------------------------------------------------- Note. Kernel memory is a limited resource, not pageable, and competes with user applications and the rest of the kernel for physical memory. Drivers that allocate a large amount of kernel memory may cause system performance to degrade. ---------------------------------------------------------------------------- void kmem_free(void *cp, size_t size); Memory allocated by kmem_alloc(9F) or by kmem_zalloc(9F) is returned to the system with kmem_free(9F). This is similar to the C library routine free(3C), with the addition of the size argument. Drivers must keep track of the size of each object they allocate in order to call kmem_free(9F) later. ---- Storage Classes of Driver Data The storage class of data is a guide to whether the driver might need to take explicit steps to control access to the data. There are three types of data storage classes: Automatic (stack) data - Because every thread has a private stack, drivers never need to lock automatic variables. Global and static data - Global and static data can be shared by any number of threads in the driver; the driver might need to lock this type of data at times. Kernel heap data - Any number of threads in the driver might share kernel heap data, such as data allocated by kmem_alloc(9F). If this data is shared, the driver might need to protect it at times. --- Kernel Functions for Drivers kmem_alloc(9F) NAME kmem_alloc, kmem_zalloc, kmem_free - allocate kernel memory SYNOPSIS #include #include void *kmem_alloc(size_t size, int flag); void *kmem_zalloc(size_t size, int flag); void kmem_free(void *buf, size_t size); INTERFACE LEVEL Architecture independent level 1 (DDI/DKI). ARGUMENTS size Number of bytes to allocate. flag Determines whether caller can sleep for memory. Possible flags are KM_SLEEP to allow sleeping until memory is available, or KM_NOSLEEP to return NULL immediately if memory is not available. buf Pointer to allocated memory. DESCRIPTION kmem_alloc() allocates size bytes of kernel memory and returns a pointer to the allocated memory. The allocated memory is at least double-word aligned, so it can hold any C data structure. No greater alignment can be assumed. flag determines whether the caller can sleep for memory. KM_SLEEP allocations may sleep but are guaranteed to succeed. KM_NOSLEEP allocations are guaranteed not to sleep but may fail (return NULL) if no memory is currently avail- able. The initial contents of memory allocated using kmem_alloc() are random garbage. kmem_zalloc() is like kmem_alloc() but returns zero-filled memory. kmem_free() frees previously allocated kernel memory. The buffer address and size must exactly match the original allocation. Memory cannot be returned piecemeal. RETURN VALUES If successful, kmem_alloc() and kmem_zalloc() return a pointer to the allocated memory. If KM_NOSLEEP is set and memory cannot be allocated without sleeping, kmem_alloc() and kmem_zalloc() return NULL. SunOS 5.6 Last change: 20 Jul 1994 1 Kernel Functions for Drivers kmem_alloc(9F) CONTEXT kmem_alloc() and kmem_zalloc() can be called from interrupt context only if the KM_NOSLEEP flag is set. They can be called from user context with any valid flag. kmem_free() can be called from user or interrupt context. SEE ALSO copyout(9F), freerbuf(9F), getrbuf(9F) Writing Device Drivers WARNINGS Memory allocated using kmem_alloc() is not paged. Available memory is therefore limited by the total physical memory on the system. It is also limited by the available kernel vir- tual address space, which is often the more restrictive con- straint on large-memory configurations. Excessive use of kernel memory is likely to affect overall system performance. Overcommitment of kernel memory will cause the system to hang or panic. Misuse of the kernel memory allocator, such as writing past the end of a buffer, using a buffer after freeing it, free- ing a buffer twice, or freeing a null or invalid pointer, will corrupt the kernel heap and may cause the system to corrupt data and/or panic. The initial contents of memory allocated using kmem_alloc() are random garbage. This random garbage may include secure kernel data. Therefore, uninitialized kernel memory should be handled carefully. For example, never copyout(9F) a potentially uninitialized buffer. NOTES kmem_alloc(0, flag) always returns NULL. kmem_free(NULL, 0) is legal. SunOS 5.6 Last change: 20 Jul 1994 2 --- Kernel Functions for Drivers bioinit(9F) NAME bioinit - initialize a buffer structure SYNOPSIS #include #include void bioinit(struct buf *bp); INTERFACE LEVEL Solaris DDI specific (Solaris DDI). ARGUMENTS bp Pointer to the buffer header structure. DESCRIPTION The bioinit() function initializes a buf(9S) structure. A buffer structure contains state information which has to be initialized if the memory for the buffer was allocated using kmem_alloc(9F). This is not necessary for a buffer allo- cated using getrbuf(9F) because getrbuf() will call bioinit() directly. CONTEXT The bioinit() function can be called from any context. EXAMPLES struct buf *bp = kmem_alloc(biosize(), KM_SLEEP); bioinit(bp); /* use buffer */ SEE ALSO biofini(9F), bioreset(9F), biosize(9F), getrbuf(9F), kmem_alloc(9F), buf(9S) Writing Device Drivers SunOS 5.6 Last change: 20 Nov 1996 1 --- Kernel Functions for Drivers biofini(9F) NAME biofini - uninitialize a buffer structure SYNOPSIS #include #include void biofini(struct buf *bp); INTERFACE LEVEL Solaris DDI specific (Solaris DDI). ARGUMENTS bp Pointer to the buffer header structure. DESCRIPTION The biofini() function uninitializes a buf(9S) structure. If a buffer structure has been allocated and initialized using kmem_alloc(9F) and bioinit(9F) it needs to be uninitialized using biofini() before calling kmem_free(9F). It is not necessary to call biofini() before freeing a buffer struc- ture using freerbuf(9F) because freerbuf() will call biofini() directly. CONTEXT The biofini() function can be called from any context. EXAMPLES struct buf *bp = kmem_alloc(biosize(), KM_SLEEP); bioinit(bp); /* use buffer */ biofini(bp); kmem_free(bp, biosize()); SEE ALSO bioinit(9F), bioreset(9F), biosize(9F), freerbuf(9F), kmem_alloc(9F), kmem_free(9F), buf(9S) Writing Device Drivers SunOS 5.6 Last change: 20 Nov 1996 1 --- (4). kmem_alloc()を使用する前に camac_s()ルーチンを細かく見直してみる camac_s()ルーチン中にトレース用の文を追加する。 onl50t[45]% vi cc.c : static int camac_s(int unit, u_short mode, u_short naf, u_short *dat) { register struct cc_device *cc; /* register struct K_REG *k = cc->k; */ : case 0x0010: /* CAMAC write */ /* E.Inoue: from */ cmn_err(CE_NOTE," camac_s: debug step02. --- camac write"); /* E.Inoue: end */ cc->k->csr |= CC_WRITE; /* E.Inoue: from */ cmn_err(CE_NOTE," camac_s: debug step03. --- camac write, cc->k->csr |= CC_W RITE; ok."); /* E.Inoue: end */ cc->k->csr |= CC_GO; /* Go! */ /* E.Inoue: from */ cmn_err(CE_NOTE," camac_s: debug step04. --- camac write, cc->k->csr |= CC_G O; ok."); /* E.Inoue: end */ while ((cc->k->csr & (CC_RDY|CC_ERR)) == 0 && counter < CC_TIMEOUT_SINGL E) counter++; if ((cc->k->csr & CC_RDY) != 0) { if ((mode & CC_BIT16) == 0) { /* E.Inoue: from */ cmn_err(CE_NOTE," camac_s: debug step05. --- camac write, enter (mode & CC_B IT16) == 0) ok."); /* E.Inoue: end */ cc->k->dhr = *dat; /* E.Inoue: from */ cmn_err(CE_NOTE," camac_s: debug step06. --- camac write, cc->k->dhr = *dat; ok."); /* E.Inoue: end */ cc->k->dlr = *(dat + 1); /* E.Inoue: from */ cmn_err(CE_NOTE," camac_s: debug step07. --- camac write, cc->k->dhr = *(dat + 1); ok."); /* E.Inoue: end */ } else { /* E.Inoue: from */ cmn_err(CE_NOTE," camac_s: debug step08. --- camac write, enter (mode & CC_B IT16) != 0) ok."); /* E.Inoue: end */ cc->k->dlr = *dat; /* E.Inoue: from */ cmn_err(CE_NOTE," camac_s: debug step09. --- camac write, cc->k->dlr = *dat; ok."); /* E.Inoue: end */ } } break; default: /* NDT */ /* E.Inoue: from */ cmn_err(CE_NOTE," camac_s: debug step09. --- camac write, enter default "); /* E.Inoue: end */ cc->k->csr |= CC_GO; /* Go! */ break; } /* E.Inoue: from */ cmn_err(CE_NOTE," camac_s: debug step10. --- finish camac write"); /* E.Inoue: end */ while ((cc->k->csr & (CC_DONE | CC_ERR)) == 0 && counter < CC_TIMEOUT_SINGLE ) counter++; cc->camac_qx = cc->k->csr; if (counter >= CC_TIMEOUT_SINGLE) { : "cc.c" 2987 lines, 76954 characters onl50t[46]% make ./script/cc_build.sh [Building for sun4u] rm -f cc.o onl50t[47]% su Password: # csh onl50t# source /.cshrc onl50t# make unload ./script/cc_unload.sh [Removing CAMAC device driver] [Removing CAMAC device driver from system] [Deleting CAMAC device files] onl50t# make load ./script/cc_load.sh [Installing CAMAC device driver] [Adding CAMAC device driver to system] [Configuring CAMAC device driver] [Making CAMAC device files] sun4u onl50t# # onl50t[48]% onl50t[48]% cam3 cam3: cam3 begin cam3: CAM_Open ok. cam3: CSETBR ok. cam3: CSETCR ok. cam3: CGENC ok. cam3: CGENZ ok. cam3: CREMI ok. cam3: nafenalam ok. cam3プログラムはここでフリーズした。 システムはパニックを起こしてリブートしてしまった。 以下はコンソール上のメッセージ。 NOTICE: camac_s: debug step01. --- enter camac_s() NOTICE: camac_s: debug step02. --- camac read NOTICE: camac_s: debug step10. --- finish camac write NOTICE: camac_s: debug step01. --- enter camac_s() NOTICE: camac_s: debug step02. --- camac write NOTICE: camac_s: debug step03. --- camac write, cc->k->csr |= CC_WRITE; ok.

ARGUMENTS userbuf User program source address from which data is transferred. driverbuf Driver destination address to which data is transferred. cn Number of bytes transferred. DESCRIPTION copyin() copies data from a user program source address to a driver buffer. The driver developer must ensure that ade- quate space is allocated for the destination address. Addresses that are word-aligned are moved most efficiently. However, the driver developer is not obligated to ensure alignment. This function automatically finds the most effi- cient move according to address alignment. RETURN VALUES Under normal conditions a 0 is returned indicating a suc- cessful copy. Otherwise, a -1 is returned if one of the following occurs: o paging fault; the driver tried to access a page of memory for which it did not have read or write access o invalid user address, such as a user area or stack area o invalid address that would have resulted in data being copied into the user block If a -1 is returned to the caller, driver entry point rou- tines should return EFAULT.

SunOS 5.6 Last change: 1 May 1996 2 --- Kernel Functions for Drivers ddi_copyin(9F) NAME ddi_copyin - copy data to a driver buffer SYNOPSIS #include #include #include int ddi_copyin(const void *buf, void *driverbuf, size_t cn, int flags); INTERFACE LEVEL Solaris DDI specific (Solaris DDI). ARGUMENTS buf Source address from which data is transferred. driverbuf Driver destination address to which data is transferred. cn Number of bytes transferred. flags Set of flag bits that provide address space infor- mation about buf. DESCRIPTION This routine is designed for use in driver ioctl(9E) rou- tines for drivers that support layered ioctls. ddi_copyin() copies data from a source address to a driver buffer. The driver developer must ensure that adequate space is allo- cated for the destination address. The flags argument is used to determine the address space information about buf. If the FKIOCTL flag is set, this indicates that buf is a kernel address, and ddi_copyin() behaves like bcopy(9F). Otherwise buf is interpreted as a user buffer address, and ddi_copyin() behaves like copyin(9F). Addresses that are word-aligned are moved most efficiently. However, the driver developer is not obliged to ensure alignment. This function automatically finds the most effi- cient move according to address alignment. RETURN VALUES ddi_copyin() returns 0, indicating a successful copy. It returns -1 if one of the following occurs: o paging fault; the driver tried to access a page of memory for which it did not have read or write access SunOS 5.6 Last change: 1 May 1996 1 Kernel Functions for Drivers ddi_copyin(9F) o invalid user address, such as a user area or stack area o invalid address that would have resulted in data being copied into the user block If a -1 is returned to the caller, driver entry point rou- tines should return EFAULT.
