A. Linux Kernels Supported by this Driver
This driver has been tested in the following Linux kernels: v2.2.18
v2.4.0. The driver is supported on v2.2 and v2.4 kernels and on x86,
alpha, and PowerPC platforms.
B. Adapters Supported by this Driver
AdvanSys (Advanced System Products, Inc.) manufactures the following
RISC-based, Bus-Mastering, Fast (10 Mhz) and Ultra (20 Mhz) Narrow
(8-bit transfer) SCSI Host Adapters for the ISA, EISA, VL, and PCI
buses and RISC-based, Bus-Mastering, Ultra (20 Mhz) Wide (16-bit
transfer) SCSI Host Adapters for the PCI bus.
The CDB counts below indicate the number of SCSI CDB (Command
Descriptor Block) requests that can be stored in the RISC chip
cache and board LRAM. A CDB is a single SCSI command. The driver
detect routine will display the number of CDBs available for each
adapter detected. The number of CDBs used by the driver can be
lowered in the BIOS by changing the 'Host Queue Size' adapter setting.

C. Linux source files modified by AdvanSys Driver
This section for historical purposes documents the changes
originally made to the Linux kernel source to add the advansys
driver. As Linux has changed some of these files have also
been modified.
1. linux/arch/i386/config.in:
bool 'AdvanSys SCSI support' CONFIG_SCSI_ADVANSYS y
2. linux/drivers/scsi/hosts.c:
#ifdef CONFIG_SCSI_ADVANSYS
#include "advansys.h"
#endif
and after "static Scsi_Host_Template builtin_scsi_hosts[] =":
#ifdef CONFIG_SCSI_ADVANSYS
ADVANSYS,
#endif
3. linux/drivers/scsi/Makefile:
ifdef CONFIG_SCSI_ADVANSYS
SCSI_SRCS := $(SCSI_SRCS) advansys.c
SCSI_OBJS := $(SCSI_OBJS) advansys.o
else
SCSI_MODULE_OBJS := $(SCSI_MODULE_OBJS) advansys.o
endif
4. linux/init/main.c:
extern void advansys_setup(char *str, int *ints);
and add the following lines to the bootsetups[] array.
#ifdef CONFIG_SCSI_ADVANSYS
{ "advansys=", advansys_setup },
#endif
D. Source Comments
1. Use tab stops set to 4 for the source files. For vi use 'se tabstops=4'.
2. This driver should be maintained in multiple files. But to make
it easier to include with Linux and to follow Linux conventions,
the whole driver is maintained in the source files advansys.h and
advansys.c. In this file logical sections of the driver begin with
a comment that contains '---'. The following are the logical sections
of the driver below.
--- Linux Version
--- Linux Include File
--- Driver Options
--- Debugging Header
--- Asc Library Constants and Macros
--- Adv Library Constants and Macros
--- Driver Constants and Macros
--- Driver Structures
--- Driver Data
--- Driver Function Prototypes
--- Linux 'Scsi_Host_Template' and advansys_setup() Functions
--- Loadable Driver Support
--- Miscellaneous Driver Functions
--- Functions Required by the Asc Library
--- Functions Required by the Adv Library
--- Tracing and Debugging Functions
--- Asc Library Functions
--- Adv Library Functions
3. The string 'XXX' is used to flag code that needs to be re-written
or that contains a problem that needs to be addressed.
4. I have stripped comments from and reformatted the source for the
Asc Library and Adv Library to reduce the size of this file. This
source can be found under the following headings. The Asc Library
is used to support Narrow Boards. The Adv Library is used to
support Wide Boards.
--- Asc Library Constants and Macros
--- Adv Library Constants and Macros
--- Asc Library Functions
--- Adv Library Functions
E. Driver Compile Time Options and Debugging
In this source file the following constants can be defined. They are
defined in the source below. Both of these options are enabled by
default.
1. ADVANSYS_ASSERT - Enable driver assertions (Def: Enabled)
Enabling this option adds assertion logic statements to the
driver. If an assertion fails a message will be displayed to
the console, but the system will continue to operate. Any
assertions encountered should be reported to the person
responsible for the driver. Assertion statements may proactively
detect problems with the driver and facilitate fixing these
problems. Enabling assertions will add a small overhead to the
execution of the driver.
2. ADVANSYS_DEBUG - Enable driver debugging (Def: Disabled)
Enabling this option adds tracing functions to the driver and
the ability to set a driver tracing level at boot time. This
option will also export symbols not required outside the driver to
the kernel name space. This option is very useful for debugging
the driver, but it will add to the size of the driver execution
image and add overhead to the execution of the driver.
The amount of debugging output can be controlled with the global
variable 'asc_dbglvl'. The higher the number the more output. By
default the debug level is 0.
If the driver is loaded at boot time and the LILO Driver Option
is included in the system, the debug level can be changed by
specifying a 5th (ASC_NUM_IOPORT_PROBE + 1) I/O Port. The
first three hex digits of the pseudo I/O Port must be set to
'deb' and the fourth hex digit specifies the debug level: 0 - F.
The following command line will look for an adapter at 0x330
and set the debug level to 2.
linux advansys=0x330,0,0,0,0xdeb2
If the driver is built as a loadable module this variable can be
defined when the driver is loaded. The following insmod command
will set the debug level to one.
insmod advansys.o asc_dbglvl=1
Debugging Message Levels:
0: Errors Only
1: High-Level Tracing
2-N: Verbose Tracing
To enable debug output to console, please make sure that:
a. System and kernel logging is enabled (syslogd, klogd running).
b. Kernel messages are routed to console output. Check
/etc/syslog.conf for an entry similar to this:
kern.* /dev/console
c. klogd is started with the appropriate -c parameter
(e.g. klogd -c 8)
This will cause printk() messages to be be displayed on the
current console. Refer to the klogd(8) and syslogd(8) man pages
for details.
Alternatively you can enable printk() to console with this
program. However, this is not the 'official' way to do this.
Debug output is logged in /var/log/messages.
main()
{
syscall(103, 7, 0, 0);
}
Increasing LOG_BUF_LEN in kernel/printk.c to something like
40960 allows more debug messages to be buffered in the kernel
and written to the console or log file.
3. ADVANSYS_STATS - Enable statistics (Def: Enabled >= v1.3.0)
Enabling this option adds statistics collection and display
through /proc to the driver. The information is useful for
monitoring driver and device performance. It will add to the
size of the driver execution image and add minor overhead to
the execution of the driver.
Statistics are maintained on a per adapter basis. Driver entry
point call counts and transfer size counts are maintained.
Statistics are only available for kernels greater than or equal
to v1.3.0 with the CONFIG_PROC_FS (/proc) file system configured.
AdvanSys SCSI adapter files have the following path name format:
/proc/scsi/advansys/[0-(ASC_NUM_BOARD_SUPPORTED-1)]
This information can be displayed with cat. For example:
cat /proc/scsi/advansys/0
When ADVANSYS_STATS is not defined the AdvanSys /proc files only
contain adapter and device configuration information.
F. Driver LILO Option
If init/main.c is modified as described in the 'Directions for Adding
the AdvanSys Driver to Linux' section (B.4.) above, the driver will
recognize the 'advansys' LILO command line and /etc/lilo.conf option.
This option can be used to either disable I/O port scanning or to limit
scanning to 1 - 4 I/O ports. Regardless of the option setting EISA and
PCI boards will still be searched for and detected. This option only
affects searching for ISA and VL boards.
Examples:
1. Eliminate I/O port scanning:
boot: linux advansys=
or
boot: linux advansys=0x0
2. Limit I/O port scanning to one I/O port:
boot: linux advansys=0x110
3. Limit I/O port scanning to four I/O ports:
boot: linux advansys=0x110,0x210,0x230,0x330
For a loadable module the same effect can be achieved by setting
the 'asc_iopflag' variable and 'asc_ioport' array when loading
the driver, e.g.
insmod advansys.o asc_iopflag=1 asc_ioport=0x110,0x330
If ADVANSYS_DEBUG is defined a 5th (ASC_NUM_IOPORT_PROBE + 1)
I/O Port may be added to specify the driver debug level. Refer to
the 'Driver Compile Time Options and Debugging' section above for
more information.
G. Tests to run before releasing new driver
1. In the supported kernels verify there are no warning or compile
errors when the kernel is built as both a driver and as a module
and with the following options:
ADVANSYS_DEBUG - enabled and disabled
CONFIG_SMP - enabled and disabled
CONFIG_PROC_FS - enabled and disabled
2. Run tests on an x86, alpha, and PowerPC with at least one narrow
card and one wide card attached to a hard disk and CD-ROM drive:
fdisk, mkfs, fsck, bonnie, copy/compare test from the
CD-ROM to the hard drive.
H. Release History
BETA-1.0 (12/23/95):
First Release
BETA-1.1 (12/28/95):
1. Prevent advansys_detect() from being called twice.
2. Add LILO 0xdeb[0-f] option to set 'asc_dbglvl'.
1.2 (1/12/96):
1. Prevent re-entrancy in the interrupt handler which
resulted in the driver hanging Linux.
2. Fix problem that prevented ABP-940 cards from being
recognized on some PCI motherboards.
3. Add support for the ABP-5140 PnP ISA card.
4. Fix check condition return status.
5. Add conditionally compiled code for Linux v1.3.X.
1.3 (2/23/96):
1. Fix problem in advansys_biosparam() that resulted in the
wrong drive geometry being returned for drives > 1GB with
extended translation enabled.
2. Add additional tracing during device initialization.
3. Change code that only applies to ISA PnP adapter.
4. Eliminate 'make dep' warning.
5. Try to fix problem with handling resets by increasing their
timeout value.
1.4 (5/8/96):
1. Change definitions to eliminate conflicts with other subsystems.
2. Add versioning code for the shared interrupt changes.
3. Eliminate problem in asc_rmqueue() with iterating after removing
a request.
4. Remove reset request loop problem from the "Known Problems or
Issues" section. This problem was isolated and fixed in the
mid-level SCSI driver.
1.5 (8/8/96):
1. Add support for ABP-940U (PCI Ultra) adapter.
2. Add support for IRQ sharing by setting the SA_SHIRQ flag for
request_irq and supplying a dev_id pointer to both request_irq()
and free_irq().
3. In AscSearchIOPortAddr11() restore a call to check_region() which
should be used before I/O port probing.
4. Fix bug in asc_prt_hex() which resulted in the displaying
the wrong data.
5. Incorporate miscellaneous Asc Library bug fixes and new microcode.
6. Change driver versioning to be specific to each Linux sub-level.
7. Change statistics gathering to be per adapter instead of global
to the driver.
8. Add more information and statistics to the adapter /proc file:
/proc/scsi/advansys[0...].
9. Remove 'cmd_per_lun' from the "Known Problems or Issues" list.
This problem has been addressed with the SCSI mid-level changes
made in v1.3.89. The advansys_select_queue_depths() function
was added for the v1.3.89 changes.
1.6 (9/10/96):
1. Incorporate miscellaneous Asc Library bug fixes and new microcode.
1.7 (9/25/96):
1. Enable clustering and optimize the setting of the maximum number
of scatter gather elements for any particular board. Clustering
increases CPU utilization, but results in a relatively larger
increase in I/O throughput.
2. Improve the performance of the request queuing functions by
adding a last pointer to the queue structure.
3. Correct problems with reset and abort request handling that
could have hung or crashed Linux.
4. Add more information to the adapter /proc file:
/proc/scsi/advansys[0...].
5. Remove the request timeout issue form the driver issues list.
6. Miscellaneous documentation additions and changes.
1.8 (10/4/96):
1. Make changes to handle the new v2.1.0 kernel memory mapping
in which a kernel virtual address may not be equivalent to its
bus or DMA memory address.
2. Change abort and reset request handling to make it yet even
more robust.
3. Try to mitigate request starvation by sending ordered requests
to heavily loaded, tag queuing enabled devices.
4. Maintain statistics on request response time.
5. Add request response time statistics and other information to
the adapter /proc file: /proc/scsi/advansys[0...].
1.9 (10/21/96):
1. Add conditionally compiled code (ASC_QUEUE_FLOW_CONTROL) to
make use of mid-level SCSI driver device queue depth flow
control mechanism. This will eliminate aborts caused by a
device being unable to keep up with requests and eliminate
repeat busy or QUEUE FULL status returned by a device.
2. Incorporate miscellaneous Asc Library bug fixes.
3. To allow the driver to work in kernels with broken module
support set 'cmd_per_lun' if the driver is compiled as a
module. This change affects kernels v1.3.89 to present.
4. Remove PCI BIOS address from the driver banner. The PCI BIOS
is relocated by the motherboard BIOS and its new address can
not be determined by the driver.
5. Add mid-level SCSI queue depth information to the adapter
/proc file: /proc/scsi/advansys[0...].
2.0 (11/14/96):
1. Change allocation of global structures used for device
initialization to guarantee they are in DMA-able memory.
Previously when the driver was loaded as a module these
structures might not have been in DMA-able memory, causing
device initialization to fail.
2.1 (12/30/96):
1. In advansys_reset(), if the request is a synchronous reset
request, even if the request serial number has changed, then
complete the request.
2. Add Asc Library bug fixes including new microcode.
3. Clear inquiry buffer before using it.
4. Correct ifdef typo.
2.2 (1/15/97):
1. Add Asc Library bug fixes including new microcode.
2. Add synchronous data transfer rate information to the
adapter /proc file: /proc/scsi/advansys[0...].
3. Change ADVANSYS_DEBUG to be disabled by default. This
will reduce the size of the driver image, eliminate execution
overhead, and remove unneeded symbols from the kernel symbol
space that were previously added by the driver.
4. Add new compile-time option ADVANSYS_ASSERT for assertion
code that used to be defined within ADVANSYS_DEBUG. This
option is enabled by default.
2.8 (5/26/97):
1. Change version number to 2.8 to synchronize the Linux driver
version numbering with other AdvanSys drivers.
2. Reformat source files without tabs to present the same view
of the file to everyone regardless of the editor tab setting
being used.
3. Add Asc Library bug fixes.
3.1A (1/8/98):
1. Change version number to 3.1 to indicate that support for
Ultra-Wide adapters (ABP-940UW) is included in this release.
2. Add Asc Library (Narrow Board) bug fixes.
3. Report an underrun condition with the host status byte set
to DID_UNDERRUN. Currently DID_UNDERRUN is defined to 0 which
causes the underrun condition to be ignored. When Linux defines
its own DID_UNDERRUN the constant defined in this file can be
removed.
4. Add patch to AscWaitTixISRDone().
5. Add support for up to 16 different AdvanSys host adapter SCSI
channels in one system. This allows four cards with four channels
to be used in one system.
3.1B (1/9/98):
1. Handle that PCI register base addresses are not always page
aligned even though ioremap() requires that the address argument
be page aligned.
3.1C (1/10/98):
1. Update latest BIOS version checked for from the /proc file.
2. Don't set microcode SDTR variable at initialization. Instead
wait until device capabilities have been detected from an Inquiry
command.
3.1D (1/21/98):
1. Improve performance when the driver is compiled as module by
allowing up to 64 scatter-gather elements instead of 8.
3.1E (5/1/98):
1. Set time delay in AscWaitTixISRDone() to 1000 ms.
2. Include SMP locking changes.
3. For v2.1.93 and newer kernels use CONFIG_PCI and new PCI BIOS
access functions.
4. Update board serial number printing.
5. Try allocating an IRQ both with and without the SA_INTERRUPT
flag set to allow IRQ sharing with drivers that do not set
the SA_INTERRUPT flag. Also display a more descriptive error
message if request_irq() fails.
6. Update to latest Asc and Adv Libraries.
3.2A (7/22/99):
1. Update Adv Library to 4.16 which includes support for
the ASC38C0800 (Ultra2/LVD) IC.
3.2B (8/23/99):
1. Correct PCI compile time option for v2.1.93 and greater
kernels, advansys_info() string, and debug compile time
option.
2. Correct DvcSleepMilliSecond() for v2.1.0 and greater
kernels. This caused an LVD detection/BIST problem problem
among other things.
3. Sort PCI cards by PCI Bus, Slot, Function ascending order
to be consistent with the BIOS.
4. Update to Asc Library S121 and Adv Library 5.2.
3.2C (8/24/99):
1. Correct PCI card detection bug introduced in 3.2B that
prevented PCI cards from being detected in kernels older
than v2.1.93.
3.2D (8/26/99):
1. Correct /proc device synchronous speed information display.
Also when re-negotiation is pending for a target device
note this condition with an * and footnote.
2. Correct initialization problem with Ultra-Wide cards that
have a pre-3.2 BIOS. A microcode variable changed locations
in 3.2 and greater BIOSes which caused WDTR to be attempted
erroneously with drives that don't support WDTR.
3.2E (8/30/99):
1. Fix compile error caused by v2.3.13 PCI structure change.
2. Remove field from ASCEEP_CONFIG that resulted in an EEPROM
checksum error for ISA cards.
3. Remove ASC_QUEUE_FLOW_CONTROL conditional code. The mid-level
SCSI changes that it depended on were never included in Linux.
3.2F (9/3/99):
1. Handle new initial function code added in v2.3.16 for all
driver versions.
3.2G (9/8/99):
1. Fix PCI board detection in v2.3.13 and greater kernels.
2. Fix comiple errors in v2.3.X with debugging enabled.
3.2H (9/13/99):
1. Add 64-bit address, long support for Alpha and UltraSPARC.
The driver has been verified to work on an Alpha system.
2. Add partial byte order handling support for Power PC and
other big-endian platforms. This support has not yet been
completed or verified.
3. For wide boards replace block zeroing of request and
scatter-gather structures with individual field initialization
to improve performance.
4. Correct and clarify ROM BIOS version detection.
3.2I (10/8/99):
1. Update to Adv Library 5.4.
2. Add v2.3.19 underrun reporting to asc_isr_callback() and
adv_isr_callback(). Remove DID_UNDERRUN constant and other
no longer needed code that previously documented the lack
of underrun handling.
3.2J (10/14/99):
1. Eliminate compile errors for v2.0 and earlier kernels.
3.2K (11/15/99):
1. Correct debug compile error in asc_prt_adv_scsi_req_q().
2. Update Adv Library to 5.5.
3. Add ifdef handling for /proc changes added in v2.3.28.
4. Increase Wide board scatter-gather list maximum length to
255 when the driver is compiled into the kernel.
3.2L (11/18/99):
1. Fix bug in adv_get_sglist() that caused an assertion failure
at line 7475. The reqp->sgblkp pointer must be initialized
to NULL in adv_get_sglist().
3.2M (11/29/99):
1. Really fix bug in adv_get_sglist().
2. Incorporate v2.3.29 changes into driver.
3.2N (4/1/00):
1. Add CONFIG_ISA ifdef code.
2. Include advansys_interrupts_enabled name change patch.
3. For >= v2.3.28 use new SCSI error handling with new function
advansys_eh_bus_reset(). Don't include an abort function
because of base library limitations.
4. For >= v2.3.28 use per board lock instead of io_request_lock.
5. For >= v2.3.28 eliminate advansys_command() and
advansys_command_done().
6. Add some changes for PowerPC (Big Endian) support, but it isn't
working yet.
7. Fix "nonexistent resource free" problem that occurred on a module
unload for boards with an I/O space >= 255. The 'n_io_port' field
is only one byte and can not be used to hold an ioport length more
than 255.
3.3A (4/4/00):
1. Update to Adv Library 5.8.
2. For wide cards add support for CDBs up to 16 bytes.
3. Eliminate warnings when CONFIG_PROC_FS is not defined.
3.3B (5/1/00):
1. Support for PowerPC (Big Endian) wide cards. Narrow cards
still need work.
2. Change bitfields to shift and mask access for endian
portability.
3.3C (10/13/00):
1. Update for latest 2.4 kernel.
2. Test ABP-480 CardBus support in 2.4 kernel - works!
3. Update to Asc Library S123.
4. Update to Adv Library 5.12.
3.3D (11/22/00):
1. Update for latest 2.4 kernel.
2. Create patches for 2.2 and 2.4 kernels.
3.3E (1/9/01):
1. Now that 2.4 is released remove ifdef code for kernel versions
less than 2.2. The driver is now only supported in kernels 2.2,
2.4, and greater.
2. Add code to release and acquire the io_request_lock in
the driver entrypoint functions: advansys_detect and
advansys_queuecommand. In kernel 2.4 the SCSI mid-level driver
still holds the io_request_lock on entry to SCSI low-level drivers.
This was supposed to be removed before 2.4 was released but never
happened. When the mid-level SCSI driver is changed all references
to the io_request_lock should be removed from the driver.
3. Simplify error handling by removing advansys_abort(),
AscAbortSRB(), AscResetDevice(). SCSI bus reset requests are
now handled by resetting the SCSI bus and fully re-initializing
the chip. This simple method of error recovery has proven to work
most reliably after attempts at different methods. Also now only
support the "new" error handling method and remove the obsolete
error handling interface.
4. Fix debug build errors.
3.3F (1/24/01):
1. Merge with ConnectCom version from Andy Kellner which
updates Adv Library to 5.14.
2. Make PowerPC (Big Endian) work for narrow cards and
fix problems writing EEPROM for wide cards.
3. Remove interrupts_enabled assertion function.
3.3G (2/16/01):
1. Return an error from narrow boards if passed a 16 byte
CDB. The wide board can already handle 16 byte CDBs.
I. Known Problems/Fix List (XXX)
1. Need to add memory mapping workaround. Test the memory mapping.
If it doesn't work revert to I/O port access. Can a test be done
safely?
2. Handle an interrupt not working. Keep an interrupt counter in
the interrupt handler. In the timeout function if the interrupt
has not occurred then print a message and run in polled mode.
3. Allow bus type scanning order to be changed.
4. Need to add support for target mode commands, cf. CAM XPT.
J. Credits (Chronological Order)
Bob Frey <bfrey@turbolinux.com.cn> wrote the AdvanSys SCSI driver
and maintained it up to 3.3F. He continues to answer questions
and help maintain the driver.
Nathan Hartwell <mage@cdc3.cdc.net> provided the directions and
basis for the Linux v1.3.X changes which were included in the
1.2 release.
Thomas E Zerucha <zerucha@shell.portal.com> pointed out a bug
in advansys_biosparam() which was fixed in the 1.3 release.
Erik Ratcliffe <erik@caldera.com> has done testing of the
AdvanSys driver in the Caldera releases.
Rik van Riel <H.H.vanRiel@fys.ruu.nl> provided a patch to
AscWaitTixISRDone() which he found necessary to make the
driver work with a SCSI-1 disk.
Mark Moran <mmoran@mmoran.com> has helped test Ultra-Wide
support in the 3.1A driver.
Doug Gilbert <dgilbert@interlog.com> has made changes and
suggestions to improve the driver and done a lot of testing.
Ken Mort <ken@mort.net> reported a DEBUG compile bug fixed
in 3.2K.
Tom Rini <trini@kernel.crashing.org> provided the CONFIG_ISA
patch and helped with PowerPC wide and narrow board support.
Philip Blundell <philip.blundell@pobox.com> provided an
advansys_interrupts_enabled patch.
Dave Jones <dave@denial.force9.co.uk> reported the compiler
warnings generated when CONFIG_PROC_FS was not defined in
the 3.2M driver.
Jerry Quinn <jlquinn@us.ibm.com> fixed PowerPC support (endian
problems) for wide cards.
Bryan Henderson <bryanh@giraffe-data.com> helped debug narrow
card error handling.
Manuel Veloso <veloso@pobox.com> worked hard on PowerPC narrow
board support and fixed a bug in AscGetEEPConfig().
Arnaldo Carvalho de Melo <acme@conectiva.com.br> made
save_flags/restore_flags changes.
Andy Kellner <AKellner@connectcom.net> continues the Advansys SCSI
driver development for ConnectCom (Version > 3.3F).
