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.

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.

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. Fix problem that prevented ABP-940 cards from being ! 430: recognized on some PCI motherboards. ! 431: 3. Add support for the ABP-5140 PnP ISA card. ! 432: 4. Fix check condition return status. ! 433: 5. Add conditionally compiled code for Linux v1.3.X. ! 434: ! 435: 1.3 (2/23/96): ! 436: 1. Fix problem in advansys_biosparam() that resulted in the ! 437: wrong drive geometry being returned for drives > 1GB with ! 438: extended translation enabled. ! 439: 2. Add additional tracing during device initialization. ! 440: 3. Change code that only applies to ISA PnP adapter. ! 441: 4. Eliminate 'make dep' warning. ! 442: 5. Try to fix problem with handling resets by increasing their ! 443: timeout value. ! 444: ! 445: 1.4 (5/8/96): ! 446: 1. Change definitions to eliminate conflicts with other subsystems. ! 447: 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.

Enable clustering and optimize the setting of the maximum number ! 479: of scatter gather elements for any particular board. Clustering ! 480: increases CPU utilization, but results in a relatively larger ! 481: increase in I/O throughput. ! 482: 2. Improve the performance of the request queuing functions by ! 483: adding a last pointer to the queue structure. ! 484: 3. Correct problems with reset and abort request handling that ! 485: could have hung or crashed Linux. ! 486: 4. Add more information to the adapter /proc file: ! 487: /proc/scsi/advansys[0...]. ! 488: 5. Remove the request timeout issue form the driver issues list. ! 489: 6. Miscellaneous documentation additions and changes. ! 490: ! 491: 1.8 (10/4/96): ! 492: 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.
