1 BusLogic MultiMaster and FlashPoint SCSI Driver for Linux 2 3 Version 2.0.15 for Linux 2.0 4 Version 2.1.15 for Linux 2.1 5 6 PRODUCTION RELEASE 7 8 17 August 1998 9 10 Leonard N. Zubkoff 11 Dandelion Digital 12 email@example.com 13 14 Copyright 1995-1998 by Leonard N. Zubkoff <firstname.lastname@example.org> 15 16 17 INTRODUCTION 18 19 BusLogic, Inc. designed and manufactured a variety of high performance SCSI 20 host adapters which share a common programming interface across a diverse 21 collection of bus architectures by virtue of their MultiMaster ASIC technology. 22 BusLogic was acquired by Mylex Corporation in February 1996, but the products 23 supported by this driver originated under the BusLogic name and so that name is 24 retained in the source code and documentation. 25 26 This driver supports all present BusLogic MultiMaster Host Adapters, and should 27 support any future MultiMaster designs with little or no modification. More 28 recently, BusLogic introduced the FlashPoint Host Adapters, which are less 29 costly and rely on the host CPU, rather than including an onboard processor. 30 Despite not having an onboard CPU, the FlashPoint Host Adapters perform very 31 well and have very low command latency. BusLogic has recently provided me with 32 the FlashPoint Driver Developer's Kit, which comprises documentation and freely 33 redistributable source code for the FlashPoint SCCB Manager. The SCCB Manager 34 is the library of code that runs on the host CPU and performs functions 35 analogous to the firmware on the MultiMaster Host Adapters. Thanks to their 36 having provided the SCCB Manager, this driver now supports the FlashPoint Host 37 Adapters as well. 38 39 My primary goals in writing this completely new BusLogic driver for Linux are 40 to achieve the full performance that BusLogic SCSI Host Adapters and modern 41 SCSI peripherals are capable of, and to provide a highly robust driver that can 42 be depended upon for high performance mission critical applications. All of 43 the major performance features can be configured from the Linux kernel command 44 line or at module initialization time, allowing individual installations to 45 tune driver performance and error recovery to their particular needs. 46 47 The latest information on Linux support for BusLogic SCSI Host Adapters, as 48 well as the most recent release of this driver and the latest firmware for the 49 BT-948/958/958D, will always be available from my Linux Home Page at URL 50 "http://sourceforge.net/projects/dandelion/". 51 52 Bug reports should be sent via electronic mail to "email@example.com". Please 53 include with the bug report the complete configuration messages reported by the 54 driver and SCSI subsystem at startup, along with any subsequent system messages 55 relevant to SCSI operations, and a detailed description of your system's 56 hardware configuration. 57 58 Mylex has been an excellent company to work with and I highly recommend their 59 products to the Linux community. In November 1995, I was offered the 60 opportunity to become a beta test site for their latest MultiMaster product, 61 the BT-948 PCI Ultra SCSI Host Adapter, and then again for the BT-958 PCI Wide 62 Ultra SCSI Host Adapter in January 1996. This was mutually beneficial since 63 Mylex received a degree and kind of testing that their own testing group cannot 64 readily achieve, and the Linux community has available high performance host 65 adapters that have been well tested with Linux even before being brought to 66 market. This relationship has also given me the opportunity to interact 67 directly with their technical staff, to understand more about the internal 68 workings of their products, and in turn to educate them about the needs and 69 potential of the Linux community. 70 71 More recently, Mylex has reaffirmed the company's interest in supporting the 72 Linux community, and I am now working on a Linux driver for the DAC960 PCI RAID 73 Controllers. Mylex's interest and support is greatly appreciated. 74 75 Unlike some other vendors, if you contact Mylex Technical Support with a 76 problem and are running Linux, they will not tell you that your use of their 77 products is unsupported. Their latest product marketing literature even states 78 "Mylex SCSI host adapters are compatible with all major operating systems 79 including: ... Linux ...". 80 81 Mylex Corporation is located at 34551 Ardenwood Blvd., Fremont, California 82 94555, USA and can be reached at 510/796-6100 or on the World Wide Web at 83 http://www.mylex.com. Mylex HBA Technical Support can be reached by electronic 84 mail at firstname.lastname@example.org, by Voice at 510/608-2400, or by FAX at 510/745-7715. 85 Contact information for offices in Europe and Japan is available on the Web 86 site. 87 88 89 DRIVER FEATURES 90 91 o Configuration Reporting and Testing 92 93 During system initialization, the driver reports extensively on the host 94 adapter hardware configuration, including the synchronous transfer parameters 95 requested and negotiated with each target device. AutoSCSI settings for 96 Synchronous Negotiation, Wide Negotiation, and Disconnect/Reconnect are 97 reported for each target device, as well as the status of Tagged Queuing. 98 If the same setting is in effect for all target devices, then a single word 99 or phrase is used; otherwise, a letter is provided for each target device to 100 indicate the individual status. The following examples 101 should clarify this reporting format: 102 103 Synchronous Negotiation: Ultra 104 105 Synchronous negotiation is enabled for all target devices and the host 106 adapter will attempt to negotiate for 20.0 mega-transfers/second. 107 108 Synchronous Negotiation: Fast 109 110 Synchronous negotiation is enabled for all target devices and the host 111 adapter will attempt to negotiate for 10.0 mega-transfers/second. 112 113 Synchronous Negotiation: Slow 114 115 Synchronous negotiation is enabled for all target devices and the host 116 adapter will attempt to negotiate for 5.0 mega-transfers/second. 117 118 Synchronous Negotiation: Disabled 119 120 Synchronous negotiation is disabled and all target devices are limited to 121 asynchronous operation. 122 123 Synchronous Negotiation: UFSNUUU#UUUUUUUU 124 125 Synchronous negotiation to Ultra speed is enabled for target devices 0 126 and 4 through 15, to Fast speed for target device 1, to Slow speed for 127 target device 2, and is not permitted to target device 3. The host 128 adapter's SCSI ID is represented by the "#". 129 130 The status of Wide Negotiation, Disconnect/Reconnect, and Tagged Queuing 131 are reported as "Enabled", Disabled", or a sequence of "Y" and "N" letters. 132 133 o Performance Features 134 135 BusLogic SCSI Host Adapters directly implement SCSI-2 Tagged Queuing, and so 136 support has been included in the driver to utilize tagged queuing with any 137 target devices that report having the tagged queuing capability. Tagged 138 queuing allows for multiple outstanding commands to be issued to each target 139 device or logical unit, and can improve I/O performance substantially. In 140 addition, BusLogic's Strict Round Robin Mode is used to optimize host adapter 141 performance, and scatter/gather I/O can support as many segments as can be 142 effectively utilized by the Linux I/O subsystem. Control over the use of 143 tagged queuing for each target device as well as individual selection of the 144 tagged queue depth is available through driver options provided on the kernel 145 command line or at module initialization time. By default, the queue depth 146 is determined automatically based on the host adapter's total queue depth and 147 the number, type, speed, and capabilities of the target devices found. In 148 addition, tagged queuing is automatically disabled whenever the host adapter 149 firmware version is known not to implement it correctly, or whenever a tagged 150 queue depth of 1 is selected. Tagged queuing is also disabled for individual 151 target devices if disconnect/reconnect is disabled for that device. 152 153 o Robustness Features 154 155 The driver implements extensive error recovery procedures. When the higher 156 level parts of the SCSI subsystem request that a timed out command be reset, 157 a selection is made between a full host adapter hard reset and SCSI bus reset 158 versus sending a bus device reset message to the individual target device 159 based on the recommendation of the SCSI subsystem. Error recovery strategies 160 are selectable through driver options individually for each target device, 161 and also include sending a bus device reset to the specific target device 162 associated with the command being reset, as well as suppressing error 163 recovery entirely to avoid perturbing an improperly functioning device. If 164 the bus device reset error recovery strategy is selected and sending a bus 165 device reset does not restore correct operation, the next command that is 166 reset will force a full host adapter hard reset and SCSI bus reset. SCSI bus 167 resets caused by other devices and detected by the host adapter are also 168 handled by issuing a soft reset to the host adapter and re-initialization. 169 Finally, if tagged queuing is active and more than one command reset occurs 170 in a 10 minute interval, or if a command reset occurs within the first 10 171 minutes of operation, then tagged queuing will be disabled for that target 172 device. These error recovery options improve overall system robustness by 173 preventing individual errant devices from causing the system as a whole to 174 lock up or crash, and thereby allowing a clean shutdown and restart after the 175 offending component is removed. 176 177 o PCI Configuration Support 178 179 On PCI systems running kernels compiled with PCI BIOS support enabled, this 180 driver will interrogate the PCI configuration space and use the I/O port 181 addresses assigned by the system BIOS, rather than the ISA compatible I/O 182 port addresses. The ISA compatible I/O port address is then disabled by the 183 driver. On PCI systems it is also recommended that the AutoSCSI utility be 184 used to disable the ISA compatible I/O port entirely as it is not necessary. 185 The ISA compatible I/O port is disabled by default on the BT-948/958/958D. 186 187 o /proc File System Support 188 189 Copies of the host adapter configuration information together with updated 190 data transfer and error recovery statistics are available through the 191 /proc/scsi/BusLogic/<N> interface. 192 193 o Shared Interrupts Support 194 195 On systems that support shared interrupts, any number of BusLogic Host 196 Adapters may share the same interrupt request channel. 197 198 199 SUPPORTED HOST ADAPTERS 200 201 The following list comprises the supported BusLogic SCSI Host Adapters as of 202 the date of this document. It is recommended that anyone purchasing a BusLogic 203 Host Adapter not in the following table contact the author beforehand to verify 204 that it is or will be supported. 205 206 FlashPoint Series PCI Host Adapters: 207 208 FlashPoint LT (BT-930) Ultra SCSI-3 209 FlashPoint LT (BT-930R) Ultra SCSI-3 with RAIDPlus 210 FlashPoint LT (BT-920) Ultra SCSI-3 (BT-930 without BIOS) 211 FlashPoint DL (BT-932) Dual Channel Ultra SCSI-3 212 FlashPoint DL (BT-932R) Dual Channel Ultra SCSI-3 with RAIDPlus 213 FlashPoint LW (BT-950) Wide Ultra SCSI-3 214 FlashPoint LW (BT-950R) Wide Ultra SCSI-3 with RAIDPlus 215 FlashPoint DW (BT-952) Dual Channel Wide Ultra SCSI-3 216 FlashPoint DW (BT-952R) Dual Channel Wide Ultra SCSI-3 with RAIDPlus 217 218 MultiMaster "W" Series Host Adapters: 219 220 BT-948 PCI Ultra SCSI-3 221 BT-958 PCI Wide Ultra SCSI-3 222 BT-958D PCI Wide Differential Ultra SCSI-3 223 224 MultiMaster "C" Series Host Adapters: 225 226 BT-946C PCI Fast SCSI-2 227 BT-956C PCI Wide Fast SCSI-2 228 BT-956CD PCI Wide Differential Fast SCSI-2 229 BT-445C VLB Fast SCSI-2 230 BT-747C EISA Fast SCSI-2 231 BT-757C EISA Wide Fast SCSI-2 232 BT-757CD EISA Wide Differential Fast SCSI-2 233 BT-545C ISA Fast SCSI-2 234 BT-540CF ISA Fast SCSI-2 235 236 MultiMaster "S" Series Host Adapters: 237 238 BT-445S VLB Fast SCSI-2 239 BT-747S EISA Fast SCSI-2 240 BT-747D EISA Differential Fast SCSI-2 241 BT-757S EISA Wide Fast SCSI-2 242 BT-757D EISA Wide Differential Fast SCSI-2 243 BT-545S ISA Fast SCSI-2 244 BT-542D ISA Differential Fast SCSI-2 245 BT-742A EISA SCSI-2 (742A revision H) 246 BT-542B ISA SCSI-2 (542B revision H) 247 248 MultiMaster "A" Series Host Adapters: 249 250 BT-742A EISA SCSI-2 (742A revisions A - G) 251 BT-542B ISA SCSI-2 (542B revisions A - G) 252 253 AMI FastDisk Host Adapters that are true BusLogic MultiMaster clones are also 254 supported by this driver. 255 256 BusLogic SCSI Host Adapters are available packaged both as bare boards and as 257 retail kits. The BT- model numbers above refer to the bare board packaging. 258 The retail kit model numbers are found by replacing BT- with KT- in the above 259 list. The retail kit includes the bare board and manual as well as cabling and 260 driver media and documentation that are not provided with bare boards. 261 262 263 FLASHPOINT INSTALLATION NOTES 264 265 o RAIDPlus Support 266 267 FlashPoint Host Adapters now include RAIDPlus, Mylex's bootable software 268 RAID. RAIDPlus is not supported on Linux, and there are no plans to support 269 it. The MD driver in Linux 2.0 provides for concatenation (LINEAR) and 270 striping (RAID-0), and support for mirroring (RAID-1), fixed parity (RAID-4), 271 and distributed parity (RAID-5) is available separately. The built-in Linux 272 RAID support is generally more flexible and is expected to perform better 273 than RAIDPlus, so there is little impetus to include RAIDPlus support in the 274 BusLogic driver. 275 276 o Enabling UltraSCSI Transfers 277 278 FlashPoint Host Adapters ship with their configuration set to "Factory 279 Default" settings that are conservative and do not allow for UltraSCSI speed 280 to be negotiated. This results in fewer problems when these host adapters 281 are installed in systems with cabling or termination that is not sufficient 282 for UltraSCSI operation, or where existing SCSI devices do not properly 283 respond to synchronous transfer negotiation for UltraSCSI speed. AutoSCSI 284 may be used to load "Optimum Performance" settings which allow UltraSCSI 285 speed to be negotiated with all devices, or UltraSCSI speed can be enabled on 286 an individual basis. It is recommended that SCAM be manually disabled after 287 the "Optimum Performance" settings are loaded. 288 289 290 BT-948/958/958D INSTALLATION NOTES 291 292 The BT-948/958/958D PCI Ultra SCSI Host Adapters have some features which may 293 require attention in some circumstances when installing Linux. 294 295 o PCI I/O Port Assignments 296 297 When configured to factory default settings, the BT-948/958/958D will only 298 recognize the PCI I/O port assignments made by the motherboard's PCI BIOS. 299 The BT-948/958/958D will not respond to any of the ISA compatible I/O ports 300 that previous BusLogic SCSI Host Adapters respond to. This driver supports 301 the PCI I/O port assignments, so this is the preferred configuration. 302 However, if the obsolete BusLogic driver must be used for any reason, such as 303 a Linux distribution that does not yet use this driver in its boot kernel, 304 BusLogic has provided an AutoSCSI configuration option to enable a legacy ISA 305 compatible I/O port. 306 307 To enable this backward compatibility option, invoke the AutoSCSI utility via 308 Ctrl-B at system startup and select "Adapter Configuration", "View/Modify 309 Configuration", and then change the "ISA Compatible Port" setting from 310 "Disable" to "Primary" or "Alternate". Once this driver has been installed, 311 the "ISA Compatible Port" option should be set back to "Disable" to avoid 312 possible future I/O port conflicts. The older BT-946C/956C/956CD also have 313 this configuration option, but the factory default setting is "Primary". 314 315 o PCI Slot Scanning Order 316 317 In systems with multiple BusLogic PCI Host Adapters, the order in which the 318 PCI slots are scanned may appear reversed with the BT-948/958/958D as 319 compared to the BT-946C/956C/956CD. For booting from a SCSI disk to work 320 correctly, it is necessary that the host adapter's BIOS and the kernel agree 321 on which disk is the boot device, which requires that they recognize the PCI 322 host adapters in the same order. The motherboard's PCI BIOS provides a 323 standard way of enumerating the PCI host adapters, which is used by the Linux 324 kernel. Some PCI BIOS implementations enumerate the PCI slots in order of 325 increasing bus number and device number, while others do so in the opposite 326 direction. 327 328 Unfortunately, Microsoft decided that Windows 95 would always enumerate the 329 PCI slots in order of increasing bus number and device number regardless of 330 the PCI BIOS enumeration, and requires that their scheme be supported by the 331 host adapter's BIOS to receive Windows 95 certification. Therefore, the 332 factory default settings of the BT-948/958/958D enumerate the host adapters 333 by increasing bus number and device number. To disable this feature, invoke 334 the AutoSCSI utility via Ctrl-B at system startup and select "Adapter 335 Configuration", "View/Modify Configuration", press Ctrl-F10, and then change 336 the "Use Bus And Device # For PCI Scanning Seq." option to OFF. 337 338 This driver will interrogate the setting of the PCI Scanning Sequence option 339 so as to recognize the host adapters in the same order as they are enumerated 340 by the host adapter's BIOS. 341 342 o Enabling UltraSCSI Transfers 343 344 The BT-948/958/958D ship with their configuration set to "Factory Default" 345 settings that are conservative and do not allow for UltraSCSI speed to be 346 negotiated. This results in fewer problems when these host adapters are 347 installed in systems with cabling or termination that is not sufficient for 348 UltraSCSI operation, or where existing SCSI devices do not properly respond 349 to synchronous transfer negotiation for UltraSCSI speed. AutoSCSI may be 350 used to load "Optimum Performance" settings which allow UltraSCSI speed to be 351 negotiated with all devices, or UltraSCSI speed can be enabled on an 352 individual basis. It is recommended that SCAM be manually disabled after the 353 "Optimum Performance" settings are loaded. 354 355 356 DRIVER OPTIONS 357 358 BusLogic Driver Options may be specified either via the Linux Kernel Command 359 Line or via the Loadable Kernel Module Installation Facility. Driver Options 360 for multiple host adapters may be specified either by separating the option 361 strings by a semicolon, or by specifying multiple "BusLogic=" strings on the 362 command line. Individual option specifications for a single host adapter are 363 separated by commas. The Probing and Debugging Options apply to all host 364 adapters whereas the remaining options apply individually only to the 365 selected host adapter. 366 367 The BusLogic Driver Probing Options comprise the following: 368 369 IO:<integer> 370 371 The "IO:" option specifies an ISA I/O Address to be probed for a non-PCI 372 MultiMaster Host Adapter. If neither "IO:" nor "NoProbeISA" options are 373 specified, then the standard list of BusLogic MultiMaster ISA I/O Addresses 374 will be probed (0x330, 0x334, 0x230, 0x234, 0x130, and 0x134). Multiple 375 "IO:" options may be specified to precisely determine the I/O Addresses to 376 be probed, but the probe order will always follow the standard list. 377 378 NoProbe 379 380 The "NoProbe" option disables all probing and therefore no BusLogic Host 381 Adapters will be detected. 382 383 NoProbeISA 384 385 The "NoProbeISA" option disables probing of the standard BusLogic ISA I/O 386 Addresses and therefore only PCI MultiMaster and FlashPoint Host Adapters 387 will be detected. 388 389 NoProbePCI 390 391 The "NoProbePCI" options disables the interrogation of PCI Configuration 392 Space and therefore only ISA Multimaster Host Adapters will be detected, as 393 well as PCI Multimaster Host Adapters that have their ISA Compatible I/O 394 Port set to "Primary" or "Alternate". 395 396 NoSortPCI 397 398 The "NoSortPCI" option forces PCI MultiMaster Host Adapters to be 399 enumerated in the order provided by the PCI BIOS, ignoring any setting of 400 the AutoSCSI "Use Bus And Device # For PCI Scanning Seq." option. 401 402 MultiMasterFirst 403 404 The "MultiMasterFirst" option forces MultiMaster Host Adapters to be probed 405 before FlashPoint Host Adapters. By default, if both FlashPoint and PCI 406 MultiMaster Host Adapters are present, this driver will probe for 407 FlashPoint Host Adapters first unless the BIOS primary disk is controlled 408 by the first PCI MultiMaster Host Adapter, in which case MultiMaster Host 409 Adapters will be probed first. 410 411 FlashPointFirst 412 413 The "FlashPointFirst" option forces FlashPoint Host Adapters to be probed 414 before MultiMaster Host Adapters. 415 416 The BusLogic Driver Tagged Queuing Options allow for explicitly specifying 417 the Queue Depth and whether Tagged Queuing is permitted for each Target 418 Device (assuming that the Target Device supports Tagged Queuing). The Queue 419 Depth is the number of SCSI Commands that are allowed to be concurrently 420 presented for execution (either to the Host Adapter or Target Device). Note 421 that explicitly enabling Tagged Queuing may lead to problems; the option to 422 enable or disable Tagged Queuing is provided primarily to allow disabling 423 Tagged Queuing on Target Devices that do not implement it correctly. The 424 following options are available: 425 426 QueueDepth:<integer> 427 428 The "QueueDepth:" or QD:" option specifies the Queue Depth to use for all 429 Target Devices that support Tagged Queuing, as well as the maximum Queue 430 Depth for devices that do not support Tagged Queuing. If no Queue Depth 431 option is provided, the Queue Depth will be determined automatically based 432 on the Host Adapter's Total Queue Depth and the number, type, speed, and 433 capabilities of the detected Target Devices. For Host Adapters that 434 require ISA Bounce Buffers, the Queue Depth is automatically set by default 435 to BusLogic_TaggedQueueDepthBB or BusLogic_UntaggedQueueDepthBB to avoid 436 excessive preallocation of DMA Bounce Buffer memory. Target Devices that 437 do not support Tagged Queuing always have their Queue Depth set to 438 BusLogic_UntaggedQueueDepth or BusLogic_UntaggedQueueDepthBB, unless a 439 lower Queue Depth option is provided. A Queue Depth of 1 automatically 440 disables Tagged Queuing. 441 442 QueueDepth:[<integer>,<integer>...] 443 444 The "QueueDepth:[...]" or "QD:[...]" option specifies the Queue Depth 445 individually for each Target Device. If an <integer> is omitted, the 446 associated Target Device will have its Queue Depth selected automatically. 447 448 TaggedQueuing:Default 449 450 The "TaggedQueuing:Default" or "TQ:Default" option permits Tagged Queuing 451 based on the firmware version of the BusLogic Host Adapter and based on 452 whether the Queue Depth allows queuing multiple commands. 453 454 TaggedQueuing:Enable 455 456 The "TaggedQueuing:Enable" or "TQ:Enable" option enables Tagged Queuing for 457 all Target Devices on this Host Adapter, overriding any limitation that 458 would otherwise be imposed based on the Host Adapter firmware version. 459 460 TaggedQueuing:Disable 461 462 The "TaggedQueuing:Disable" or "TQ:Disable" option disables Tagged Queuing 463 for all Target Devices on this Host Adapter. 464 465 TaggedQueuing:<Target-Spec> 466 467 The "TaggedQueuing:<Target-Spec>" or "TQ:<Target-Spec>" option controls 468 Tagged Queuing individually for each Target Device. <Target-Spec> is a 469 sequence of "Y", "N", and "X" characters. "Y" enables Tagged Queuing, "N" 470 disables Tagged Queuing, and "X" accepts the default based on the firmware 471 version. The first character refers to Target Device 0, the second to 472 Target Device 1, and so on; if the sequence of "Y", "N", and "X" characters 473 does not cover all the Target Devices, unspecified characters are assumed 474 to be "X". 475 476 The BusLogic Driver Miscellaneous Options comprise the following: 477 478 BusSettleTime:<seconds> 479 480 The "BusSettleTime:" or "BST:" option specifies the Bus Settle Time in 481 seconds. The Bus Settle Time is the amount of time to wait between a Host 482 Adapter Hard Reset which initiates a SCSI Bus Reset and issuing any SCSI 483 Commands. If unspecified, it defaults to BusLogic_DefaultBusSettleTime. 484 485 InhibitTargetInquiry 486 487 The "InhibitTargetInquiry" option inhibits the execution of an Inquire 488 Target Devices or Inquire Installed Devices command on MultiMaster Host 489 Adapters. This may be necessary with some older Target Devices that do not 490 respond correctly when Logical Units above 0 are addressed. 491 492 The BusLogic Driver Debugging Options comprise the following: 493 494 TraceProbe 495 496 The "TraceProbe" option enables tracing of Host Adapter Probing. 497 498 TraceHardwareReset 499 500 The "TraceHardwareReset" option enables tracing of Host Adapter Hardware 501 Reset. 502 503 TraceConfiguration 504 505 The "TraceConfiguration" option enables tracing of Host Adapter 506 Configuration. 507 508 TraceErrors 509 510 The "TraceErrors" option enables tracing of SCSI Commands that return an 511 error from the Target Device. The CDB and Sense Data will be printed for 512 each SCSI Command that fails. 513 514 Debug 515 516 The "Debug" option enables all debugging options. 517 518 The following examples demonstrate setting the Queue Depth for Target Devices 519 1 and 2 on the first host adapter to 7 and 15, the Queue Depth for all Target 520 Devices on the second host adapter to 31, and the Bus Settle Time on the 521 second host adapter to 30 seconds. 522 523 Linux Kernel Command Line: 524 525 linux BusLogic=QueueDepth:[,7,15];QueueDepth:31,BusSettleTime:30 526 527 LILO Linux Boot Loader (in /etc/lilo.conf): 528 529 append = "BusLogic=QueueDepth:[,7,15];QueueDepth:31,BusSettleTime:30" 530 531 INSMOD Loadable Kernel Module Installation Facility: 532 533 insmod BusLogic.o \ 534 'BusLogic="QueueDepth:[,7,15];QueueDepth:31,BusSettleTime:30"' 535 536 NOTE: Module Utilities 2.1.71 or later is required for correct parsing 537 of driver options containing commas. 538 539 540 DRIVER INSTALLATION 541 542 This distribution was prepared for Linux kernel version 2.0.35, but should be 543 compatible with 2.0.4 or any later 2.0 series kernel. 544 545 To install the new BusLogic SCSI driver, you may use the following commands, 546 replacing "/usr/src" with wherever you keep your Linux kernel source tree: 547 548 cd /usr/src 549 tar -xvzf BusLogic-2.0.15.tar.gz 550 mv README.* LICENSE.* BusLogic.[ch] FlashPoint.c linux/drivers/scsi 551 patch -p0 < BusLogic.patch (only for 2.0.33 and below) 552 cd linux 553 make config 554 make zImage 555 556 Then install "arch/x86/boot/zImage" as your standard kernel, run lilo if 557 appropriate, and reboot. 558 559 560 BUSLOGIC ANNOUNCEMENTS MAILING LIST 561 562 The BusLogic Announcements Mailing List provides a forum for informing Linux 563 users of new driver releases and other announcements regarding Linux support 564 for BusLogic SCSI Host Adapters.
