42: A. 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.

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. Add the following lines to /usr/src/linux/drivers/scsi/hosts.c
120: after "#include "hosts.h"":
121:
122: #ifdef CONFIG_SCSI_ADVANSYS
123: #include "advansys.h"
124: #endif
125:
126: and after "static Scsi_Host_Template builtin_scsi_hosts[] =":
127:
128: #ifdef CONFIG_SCSI_ADVANSYS
129: ADVANSYS,
130: #endif
131:
132: 3. Add the following lines to /usr/src/linux/drivers/scsi/Makefile:
133:
134: ifdef CONFIG_SCSI_ADVANSYS
135: SCSI_SRCS := $(SCSI_SRCS) advansys.c
136: SCSI_OBJS := $(SCSI_OBJS) advansys.o
137: else
138: SCSI_MODULE_OBJS := $(SCSI_MODULE_OBJS) advansys.o
139: endif
140:
141: 4. (Optional) If you would like to enable the LILO command line
142: and /etc/lilo.conf 'advansys' option, make the following changes.
143: This option can be used to disable I/O port scanning or to limit
144: I/O port scanning to specific addresses. Refer to the 'Driver
145: LILO Option' section below. Add the following lines to
146: /usr/src/linux/init/main.c in the prototype section:
147:
148: extern void advansys_setup(char *str, int *ints);
149:
150: and add the following lines to the bootsetups[] array.
151:
152: #ifdef CONFIG_SCSI_ADVANSYS
153: { "advansys=", advansys_setup },
154: #endif
155:
156: 5. 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. Add the following line to /usr/src/linux/drivers/scsi/Config.in
187: after "comment 'SCSI low-level drivers'":
188:
189: dep_tristate 'AdvanSys SCSI support' CONFIG_SCSI_ADVANSYS $CONFIG_SCSI
190:
191: 2. Add the following lines to /usr/src/linux/drivers/scsi/hosts.c
192: after "#include "hosts.h"":
193:
194: #ifdef CONFIG_SCSI_ADVANSYS
195: #include "advansys.h"
196: #endif
197:
198: and after "static Scsi_Host_Template builtin_scsi_hosts[] =":
199:
200: #ifdef CONFIG_SCSI_ADVANSYS
201: ADVANSYS,
202: #endif
203:
204: 3. Add the following lines to /usr/src/linux/drivers/scsi/Makefile:
205:
206: ifeq ($(CONFIG_SCSI_ADVANSYS),y)
207: L_OBJS += advansys.o
208: else
209: ifeq ($(CONFIG_SCSI_ADVANSYS),m)
210: M_OBJS += advansys.o
211: endif
212: endif
213:
214: 4. Add the following line to /usr/src/linux/include/linux/proc_fs.h
215: in the enum scsi_directory_inos array:
216:
217: PROC_SCSI_ADVANSYS,
218:
219: 5. (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. In the directory /usr/src/linux run 'make config' to configure
235: the AdvanSys driver, then run 'make vmlinux' or 'make zlilo' to
236: make the kernel. If the AdvanSys driver is not configured, then
237: a loadable module can be built by running 'make modules' and
238: 'make modules_install'. 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

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

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:

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. 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.
