Linux Kernel Testing 43: 44: This driver has been tested in the following Linux kernels: v1.2.13, 45: v1.3.57, v2.0.33, v2.1.77. These kernel versions are major releases 46: of Linux or the latest Linux kernel versions available when this version 47: of the driver was released. The driver should also work in earlier 48: versions of the Linux kernel. Beginning with v1.3.58 the AdvanSys driver 49: is included with all Linux kernels. Please refer to sections C, D, and 50: E for instructions on adding or upgrading the AdvanSys driver. 51: 52: B. Adapters Supported by this Driver 53: 54: AdvanSys (Advanced System Products, Inc.) manufactures the following 55: RISC-based, Bus-Mastering, Fast (10 Mhz) and Ultra (20 Mhz) Narrow 56: (8-bit transfer) SCSI Host Adapters for the ISA, EISA, VL, and PCI 57: buses and RISC-based, Bus-Mastering, Ultra (20 Mhz) Wide (16-bit 58: transfer) SCSI Host Adapters for the PCI bus. 59: 60: The CDB counts below indicate the number of SCSI CDB (Command 61: Descriptor Block) requests that can be stored in the RISC chip 62: cache and board LRAM. A CDB is a single SCSI command. The driver 63: detect routine will display the number of CDBs available for each 64: adapter detected. The number of CDBs used by the driver can be 65: lowered in the BIOS by changing the 'Host Queue Size' adapter setting. 66: 67: Connectivity Products: 68: ABP510/5150 - Bus-Master ISA (240 CDB) (Footnote 1) 69: ABP5140 - Bus-Master ISA PnP (16 CDB) (Footnote 1, 3) 70: ABP5142 - Bus-Master ISA PnP with floppy (16 CDB) (Footnote 4) 71: ABP920 - Bus-Master PCI (16 CDB) 72: ABP930 - Bus-Master PCI (16 CDB) (Footnote 5) 73: ABP930U - Bus-Master PCI Ultra (16 CDB) 74: ABP930UA - Bus-Master PCI Ultra (16 CDB) 75: ABP960 - Bus-Master PCI MAC/PC (16 CDB) (Footnote 2) 76: ABP960U - Bus-Master PCI MAC/PC Ultra (16 CDB) (Footnote 2) 77: 78: Single Channel Products: 79: ABP542 - Bus-Master ISA with floppy (240 CDB) 80: ABP742 - Bus-Master EISA (240 CDB) 81: ABP842 - Bus-Master VL (240 CDB) 82: ABP940 - Bus-Master PCI (240 CDB) 83: ABP940U - Bus-Master PCI Ultra (240 CDB) 84: ABP970 - Bus-Master PCI MAC/PC (240 CDB) 85: ABP970U - Bus-Master PCI MAC/PC Ultra (240 CDB) 86: ABP940UW - Bus-Master PCI Ultra-Wide (240 CDB) 87: 88: Multi Channel Products: 89: ABP752 - Dual Channel Bus-Master EISA (240 CDB Per Channel) 90: ABP852 - Dual Channel Bus-Master VL (240 CDB Per Channel) 91: ABP950 - Dual Channel Bus-Master PCI (240 CDB Per Channel) 92: ABP980 - Four Channel Bus-Master PCI (240 CDB Per Channel) 93: ABP980U - Four Channel Bus-Master PCI Ultra (240 CDB Per Channel) 94: 95: Footnotes: 96: 1. This board has been shipped by HP with the 4020i CD-R drive. 97: The board has no BIOS so it cannot control a boot device, but 98: it can control any secondary SCSI device. 99: 2. This board has been sold by Iomega as a Jaz Jet PCI adapter. 100: 3. This board has been sold by SIIG as the i540 SpeedMaster. 101: 4. This board has been sold by SIIG as the i542 SpeedMaster. 102: 5. This board has been sold by SIIG as the Fast SCSI Pro PCI. 103: 104: C. Linux v1.2.X - Directions for Adding the AdvanSys Driver 105: 106: These directions apply to v1.2.13. For versions that follow v1.2.13. 107: but precede v1.3.57 some of the changes for Linux v1.3.X listed 108: below may need to be modified or included. A patch is available 109: for v1.2.13 from the AdvanSys WWW and FTP sites. 110: 111: There are two source files: advansys.h and advansys.c. Copy 112: both of these files to the directory /usr/src/linux/drivers/scsi. 113: 114: 1. Add the following line to /usr/src/linux/arch/i386/config.in 115: after "comment 'SCSI low-level drivers'": 116: 117: bool 'AdvanSys SCSI support' CONFIG_SCSI_ADVANSYS y 118: 119: 2.

If you have the HP 4020i CD-R driver and Linux v1.2.X you should 157: add a fix to the CD-ROM target driver. This fix will allow 158: you to mount CDs with the iso9660 file system. Linux v1.3.X 159: already has this fix. In the file /usr/src/linux/drivers/scsi/sr.c 160: and function get_sectorsize() after the line: 161: 162: if(scsi_CDs[i].sector_size == 0) scsi_CDs[i].sector_size = 2048; 163: 164: add the following line: 165: 166: if(scsi_CDs[i].sector_size == 2340) scsi_CDs[i].sector_size = 2048; 167: 168: 6. In the directory /usr/src/linux run 'make config' to configure 169: the AdvanSys driver, then run 'make vmlinux' or 'make zlilo' to 170: make the kernel. If the AdvanSys driver is not configured, then 171: a loadable module can be built by running 'make modules' and 172: 'make modules_install'. Use 'insmod' and 'rmmod' to install 173: and remove advansys.o. 174: 175: D. Linux v1.3.1 - v1.3.57 - Directions for Adding the AdvanSys Driver 176: 177: These directions apply to v1.3.57. For versions that precede v1.3.57 178: some of these changes may need to be modified or eliminated. A patch 179: is available for v1.3.57 from the AdvanSys WWW and FTP sites. 180: Beginning with v1.3.58 this driver is included with the Linux 181: distribution eliminating the need for making any changes. 182: 183: There are two source files: advansys.h and advansys.c. Copy 184: both of these files to the directory /usr/src/linux/drivers/scsi. 185: 186: 1.

(Optional) If you would like to enable the LILO command line 220: and /etc/lilo.conf 'advansys' option, make the following changes. 221: This option can be used to disable I/O port scanning or to limit 222: I/O port scanning to specific addresses. Refer to the 'Driver 223: LILO Option' section below. Add the following lines to 224: /usr/src/linux/init/main.c in the prototype section: 225: 226: extern void advansys_setup(char *str, int *ints); 227: 228: and add the following lines to the bootsetups[] array. 229: 230: #ifdef CONFIG_SCSI_ADVANSYS 231: { "advansys=", advansys_setup }, 232: #endif 233: 234: 6.

Use 'insmod' and 'rmmod' to install 239: and remove advansys.o. 240: 241: E. Linux v1.3.58 and Newer - Upgrading the AdvanSys Driver 242: 243: To upgrade the AdvanSys driver in a Linux v1.3.58 and newer 244: kernel, first check the version of the current driver. The 245: version is defined by the manifest constant ASC_VERSION at 246: the beginning of advansys.c. The new driver should have a 247: ASC_VERSION value greater than the current version. To install 248: the new driver rename advansys.c and advansys.h in the Linux 249: kernel source tree drivers/scsi directory to different names 250: or save them to a different directory in case you want to revert 251: to the old version of the driver. After the old driver is saved 252: copy the new advansys.c and advansys.h to drivers/scsi, rebuild 253: the kernel, and install the new kernel. No other changes are needed. 254: 255: F. Source Comments 256: 257: 1. Use tab stops set to 4 for the source files. For vi use 'se tabstops=4'. 258: 259: 2. This driver should be maintained in multiple files. But to make 260: it easier to include with Linux and to follow Linux conventions, 261: the whole driver is maintained in the source files advansys.h and 262: advansys.c. In this file logical sections of the driver begin with 263: a comment that contains '---'. The following are the logical sections 264: of the driver below. 265: 266: --- Linux Version 267: --- Linux Include Files 268: --- Driver Options 269: --- Debugging Header 270: --- Asc Library Constants and Macros 271: --- Adv Library Constants and Macros 272: --- Driver Constants and Macros 273: --- Driver Structures 274: --- Driver Data 275: --- Driver Function Prototypes 276: --- Linux 'Scsi_Host_Template' and advansys_setup() Functions 277: --- Loadable Driver Support 278: --- Miscellaneous Driver Functions 279: --- Functions Required by the Asc Library 280: --- Functions Required by the Adv Library 281: --- Tracing and Debugging Functions 282: --- Asc Library Functions 283: --- Adv Library Functions 284: 285: 3. The string 'XXX' is used to flag code that needs to be re-written 286: or that contains a problem that needs to be addressed. 287: 288: 4. I have stripped comments from and reformatted the source for the 289: Asc Library and Adv Library to reduce the size of this file. This 290: source can be found under the following headings. The Asc Library 291: is used to support Narrow Boards. The Adv Library is used to 292: support Wide Boards. 293: 294: --- Asc Library Constants and Macros 295: --- Adv Library Constants and Macros 296: --- Asc Library Functions 297: --- Adv Library Functions 298: 299: G. Driver Compile Time Options and Debugging 300: 301: In this source file the following constants can be defined. They are 302: defined in the source below. Both of these options are enabled by 303: default. 304: 305: 1. ADVANSYS_ASSERT - Enable driver assertions (Def: Enabled) 306: 307: Enabling this option adds assertion logic statements to the 308: driver. If an assertion fails a message will be displayed to 309: the console, but the system will continue to operate. Any 310: assertions encountered should be reported to the person 311: responsible for the driver. Assertion statements may proactively 312: detect problems with the driver and facilitate fixing these 313: problems. Enabling assertions will add a small overhead to the 314: execution of the driver. 315: 316: 2. ADVANSYS_DEBUG - Enable driver debugging (Def: Disabled) 317: 318: Enabling this option adds tracing functions to the driver and 319: the ability to set a driver tracing level at boot time. This 320: option will also export symbols not required outside the driver to 321: the kernel name space. This option is very useful for debugging 322: the driver, but it will add to the size of the driver execution 323: image and add overhead to the execution of the driver. 324: 325: The amount of debugging output can be controlled with the global 326: variable 'asc_dbglvl'. The higher the number the more output. By 327: default the debug level is 0. 328: 329: If the driver is loaded at boot time and the LILO Driver Option 330: is included in the system, the debug level can be changed by 331: specifying a 5th (ASC_NUM_IOPORT_PROBE + 1) I/O Port. The 332: first three hex digits of the pseudo I/O Port must be set to 333: 'deb' and the fourth hex digit specifies the debug level: 0 - F. 334: The following command line will look for an adapter at 0x330 335: and set the debug level to 2. 336: 337: linux advansys=0x330,0,0,0,0xdeb2 338: 339: If the driver is built as a loadable module this variable can be 340: defined when the driver is loaded. The following insmod command 341: will set the debug level to one. 342: 343: insmod advansys.o asc_dbglvl=1 344: 345: Debugging Message Levels: 346: 0: Errors Only 347: 1: High-Level Tracing 348: 2-N: Verbose Tracing 349: 350: I don't know the approved way for turning on printk()s to the 351: console. Here's a program I use to do this. Debug output is 352: logged in /var/adm/messages. 353: 354: main() 355: { 356: syscall(103, 7, 0, 0); 357: } 358: 359: I found that increasing LOG_BUF_LEN to 40960 in kernel/printk.c 360: prevents most level 1 debug messages from being lost. 361: 362: 3. ADVANSYS_STATS - Enable statistics (Def: Enabled >= v1.3.0) 363: 364: Enabling this option adds statistics collection and display 365: through /proc to the driver. The information is useful for 366: monitoring driver and device performance. It will add to the 367: size of the driver execution image and add minor overhead to 368: the execution of the driver. 369: 370: Statistics are maintained on a per adapter basis. Driver entry 371: point call counts and transfer size counts are maintained. 372: Statistics are only available for kernels greater than or equal 373: to v1.3.0 with the CONFIG_PROC_FS (/proc) file system configured. 374: 375: AdvanSys SCSI adapter files have the following path name format: 376: 377: /proc/scsi/advansys/[0-(ASC_NUM_BOARD_SUPPORTED-1)] 378: 379: This information can be displayed with cat. For example: 380: 381: cat /proc/scsi/advansys/0 382: 383: When ADVANSYS_STATS is not defined the AdvanSys /proc files only 384: contain adapter and device configuration information. 385: 386: H. Driver LILO Option 387: 388: If init/main.c is modified as described in the 'Directions for Adding 389: the AdvanSys Driver to Linux' section (B.4.) above, the driver will 390: recognize the 'advansys' LILO command line and /etc/lilo.conf option. 391: This option can be used to either disable I/O port scanning or to limit 392: scanning to 1 - 4 I/O ports. Regardless of the option setting EISA and 393: PCI boards will still be searched for and detected. This option only 394: affects searching for ISA and VL boards. 395: 396: Examples: 397: 1. Eliminate I/O port scanning: 398: boot: linux advansys= 399: or 400: boot: linux advansys=0x0 401: 2. Limit I/O port scanning to one I/O port: 402: boot: linux advansys=0x110 403: 3. Limit I/O port scanning to four I/O ports: 404: boot: linux advansys=0x110,0x210,0x230,0x330 405: 406: For a loadable module the same effect can be achieved by setting 407: the 'asc_iopflag' variable and 'asc_ioport' array when loading 408: the driver, e.g. 409: 410: insmod advansys.o asc_iopflag=1 asc_ioport=0x110,0x330 411: 412: If ADVANSYS_DEBUG is defined a 5th (ASC_NUM_IOPORT_PROBE + 1) 413: I/O Port may be added to specify the driver debug level. Refer to 414: the 'Driver Compile Time Options and Debugging' section above for 415: more information. 416: 417: I. Release History 418: 419: BETA-1.0 (12/23/95): 420: First Release 421: 422: BETA-1.1 (12/28/95): 423: 1. Prevent advansys_detect() from being called twice. 424: 2. Add LILO 0xdeb[0-f] option to set 'asc_dbglvl'. 425: 426: 1.2 (1/12/96): 427: 1. Prevent re-entrancy in the interrupt handler which 428: resulted in the driver hanging Linux. 429: 2.

Add versioning code for the shared interrupt changes. 448: 3. Eliminate problem in asc_rmqueue() with iterating after removing 449: a request. 450: 4. Remove reset request loop problem from the "Known Problems or 451: Issues" section. This problem was isolated and fixed in the 452: mid-level SCSI driver. 453: 454: 1.5 (8/8/96): 455: 1. Add support for ABP-940U (PCI Ultra) adapter. 456: 2. Add support for IRQ sharing by setting the SA_SHIRQ flag for 457: request_irq and supplying a dev_id pointer to both request_irq() 458: and free_irq(). 459: 3. In AscSearchIOPortAddr11() restore a call to check_region() which 460: should be used before I/O port probing. 461: 4. Fix bug in asc_prt_hex() which resulted in the displaying 462: the wrong data. 463: 5. Incorporate miscellaneous Asc Library bug fixes and new microcode. 464: 6. Change driver versioning to be specific to each Linux sub-level. 465: 7. Change statistics gathering to be per adapter instead of global 466: to the driver. 467: 8. Add more information and statistics to the adapter /proc file: 468: /proc/scsi/advansys[0...]. 469: 9. Remove 'cmd_per_lun' from the "Known Problems or Issues" list. 470: This problem has been addressed with the SCSI mid-level changes 471: made in v1.3.89. The advansys_select_queue_depths() function 472: was added for the v1.3.89 changes. 473: 474: 1.6 (9/10/96): 475: 1. Incorporate miscellaneous Asc Library bug fixes and new microcode. 476: 477: 1.7 (9/25/96): 478: 1.

Make changes to handle the new v2.1.0 kernel memory mapping 493: in which a kernel virtual address may not be equivalent to its 494: bus or DMA memory address. 495: 2. Change abort and reset request handling to make it yet even 496: more robust. 497: 3. Try to mitigate request starvation by sending ordered requests 498: to heavily loaded, tag queuing enabled devices. 499: 4. Maintain statistics on request response time. 500: 5. Add request response time statistics and other information to 501: the adapter /proc file: /proc/scsi/advansys[0...]. 502: 503: 1.9 (10/21/96): 504: 1. Add conditionally compiled code (ASC_QUEUE_FLOW_CONTROL) to 505: make use of mid-level SCSI driver device queue depth flow 506: control mechanism. This will eliminate aborts caused by a 507: device being unable to keep up with requests and eliminate 508: repeat busy or QUEUE FULL status returned by a device. 509: 2. Incorporate miscellaneous Asc Library bug fixes. 510: 3. To allow the driver to work in kernels with broken module 511: support set 'cmd_per_lun' if the driver is compiled as a 512: module. This change affects kernels v1.3.89 to present. 513: 4. Remove PCI BIOS address from the driver banner. The PCI BIOS 514: is relocated by the motherboard BIOS and its new address can 515: not be determined by the driver. 516: 5. Add mid-level SCSI queue depth information to the adapter 517: /proc file: /proc/scsi/advansys[0...]. 518: 519: 2.0 (11/14/96): 520: 1. Change allocation of global structures used for device 521: initialization to guarantee they are in DMA-able memory. 522: Previously when the driver was loaded as a module these 523: structures might not have been in DMA-able memory, causing 524: device initialization to fail. 525: 526: 2.1 (12/30/96): 527: 1. In advansys_reset(), if the request is a synchronous reset 528: request, even if the request serial number has changed, then 529: complete the request. 530: 2. Add Asc Library bug fixes including new microcode. 531: 3. Clear inquiry buffer before using it. 532: 4. Correct ifdef typo. 533: 534: 2.2 (1/15/97): 535: 1. Add Asc Library bug fixes including new microcode. 536: 2. Add synchronous data transfer rate information to the 537: adapter /proc file: /proc/scsi/advansys[0...]. 538: 3. Change ADVANSYS_DEBUG to be disabled by default. This 539: will reduce the size of the driver image, eliminate execution 540: overhead, and remove unneeded symbols from the kernel symbol 541: space that were previously added by the driver. 542: 4. Add new compile-time option ADVANSYS_ASSERT for assertion 543: code that used to be defined within ADVANSYS_DEBUG. This 544: option is enabled by default. 545: 546: 2.8 (5/26/97): 547: 1. Change version number to 2.8 to synchronize the Linux driver 548: version numbering with other AdvanSys drivers. 549: 2. Reformat source files without tabs to present the same view 550: of the file to everyone regardless of the editor tab setting 551: being used. 552: 3. Add Asc Library bug fixes. 553: 554: 3.1A (1/8/98): 555: 1. Change version number to 3.1 to indicate that support for 556: Ultra-Wide adapters (ABP-940UW) is included in this release. 557: 2. Add Asc Library (Narrow Board) bug fixes. 558: 3. Report an underrun condition with the host status byte set 559: to DID_UNDERRUN. Currently DID_UNDERRUN is defined to 0 which 560: causes the underrun condition to be ignored. When Linux defines 561: its own DID_UNDERRUN the constant defined in this file can be 562: removed. 563: 4. Add patch to AscWaitTixISRDone(). 564: 5. Add support for up to 16 different AdvanSys host adapter SCSI 565: channels in one system. This allows four cards with four channels 566: to be used in one system. 567: 568: 3.1B (1/9/98): 569: 1. Handle that PCI register base addresses are not always page 570: aligned even though ioremap() requires that the address argument 571: be page aligned. 572: 573: 3.1C (1/10/98): 574: 1. Update latest BIOS version checked for from the /proc file. 575: 2. Don't set microcode SDTR variable at initialization. Instead 576: wait until device capabilities have been detected from an Inquiry 577: command. 578: 579: 3.1D (1/21/98): 580: 1. Improve performance when the driver is compiled as module by 581: allowing up to 64 scatter-gather elements instead of 8. 582: 583: 3.1E (5/1/98): 584: 1. Set time delay in AscWaitTixISRDone() to 1000 ms. 585: 2. Include SMP locking changes. 586: 3. For v2.1.93 and newer kernels use CONFIG_PCI and new PCI BIOS 587: access functions. 588: 4. Update board serial number printing. 589: 5. Try allocating an IRQ both with and without the SA_INTERRUPT 590: flag set to allow IRQ sharing with drivers that do not set 591: the SA_INTERRUPT flag. Also display a more descriptive error 592: message if request_irq() fails. 593: 5. Update to latest Asc and Adv Libraries. 594: 595: J. Known Problems or Issues 596: 597: 1. Remove conditional constants (ASC_QUEUE_FLOW_CONTROL) around 598: the queue depth flow control code when mid-level SCSI changes 599: are included in Linux. 600: 601: K. Credits 602: 603: Nathan Hartwell <[email protected]> provided the directions and 604: basis for the Linux v1.3.X changes which were included in the 605: 1.2 release. 606: 607: Thomas E Zerucha <[email protected]> pointed out a bug 608: in advansys_biosparam() which was fixed in the 1.3 release. 609: 610: Erik Ratcliffe <[email protected]> has done testing of the 611: AdvanSys driver in the Caldera releases. 612: 613: Rik van Riel <[email protected]> provided a patch to 614: AscWaitTixISRDone() which he found necessary to make the 615: driver work with a SCSI-1 disk. 616: 617: Mark Moran <[email protected]> has helped test Ultra-Wide 618: support in the 3.1A driver. 619: 620: L.
