If the initial DEVCONFIG value is divisible by 2, then the correct
setting for that controller is 0. If it's an odd number, then
the correct setting for that controller is 1. For any other
controllers that didn't have an infinite reset problem, then reverse
the above options. If DEVCONFIG was even, then the correct setting
is 1, if not then the correct setting is 0.
Now that you know what the correct setting was for each controller,
we need to encode that into the aic7xxx=stpwlev:0x... variable.
This variable is a bit field encoded variable. Bit 0 is for the first
aic7xxx controller, bit 1 for the next, etc. Put all these bits
together and you get a number. For example, if the third aic7xxx
needed a 1, but the second and first both needed a 0, then the bits
would be 100 in binary. This then translates to 0x04. You would
therefore set aic7xxx=stpwlev:0x04. This is fairly standard binary
to hexadecimal conversions here. If you aren't up to speed on the
binary->hex conversion then send an email to the aic7xxx mailing
list and someone can help you out.
"aic7xxx=tag_info:{{8,8..},{8,8..},..}" - This option is used to disable
or enable Tagged Command Queueing (TCQ) on specific devices. As of
driver version 5.1.11, TCQ is now either on or off by default
according to the setting you choose during the make config process.
In order to en/disable TCQ for certian devices at boot time, a user
may use this boot param. The driver will then parse this message out
and en/disable the specific device entries that are present based upon
the value given. The param line is parsed in the following manner:
{ - first instance indicates the start of this parameter values
second instance is the start of entries for a particular
device entry
} - end the entries for a particular host adapter, or end the entire
set of parameter entries
, - move to next entry. Inside of a set of device entries, this
moves us to the next device on the list. Outside of device
entries, this moves us to the next host adapter
. - Same effect as , but is safe to use with insmod.
x - the number to enter into the array at this position.
0 = Enable tagged queueing on this device and use the default
queue depth
1-254 = Enable tagged queueing on this device and use this
number as the queue depth
255 = Disable tagged queueing on this device.
Note: anything above 32 for an actual queue depth is wasteful
and not recommended.
A few examples of how this can be used:
tag_info:{{8,12,,0,,255,4}}
This line will only effect the first aic7xxx card registered. It
will set scsi id 0 to a queue depth of 8, id 1 to 12, leave id 2
at the default, set id 3 to tagged queueing enabled and use the
default queue depth, id 4 default, id 5 disabled, and id 6 to 4.
Any not specified entries stay at the default value, repeated
commas with no value specified will simply increment to the next id
without changing anything for the missing values.
tag_info:{,,,{,,,255}}
First, second, and third adapters at default values. Fourth
adapter, id 3 is disabled. Notice that leading commas simply
increment what the first number effects, and there are no need
for trailing commas. When you close out an adapter, or the
entire entry, anything not explicitly set stays at the default
value.
A final note on this option. The scanner I used for this isn't
perfect or highly robust. If you mess the line up, the worst that
should happen is that the line will get ignored. If you don't
close out the entire entry with the final bracket, then any other
aic7xxx options after this will get ignored. So, in general, be
sure of what you are entering, and after you have it right, just
add it to the lilo.conf file so there won't be any mistakes. As
a means of checking this parser, the entire tag_info array for
each card is now printed out in the /proc/scsi/aic7xxx/x file. You
can use that to verify that your options were parsed correctly.
Boot command line options may be combined to form the proper set of options
a user might need. For example, the following is valid:
aic7xxx=verbose,extended,irq_trigger:1
The only requirement is that individual options be separated by a comma or
a period on the command line.
Module Loading command options
------------------------------
When loading the aic7xxx driver as a module, the exact same options are
available to the user. However, the syntax to specify the options changes
slightly. For insmod, you need to wrap the aic7xxx= argument in quotes
and replace all ',' with '.'. So, for example, a valid insmod line
would be:
insmod aic7xxx aic7xxx='verbose.irq_trigger:1.extended'
This line should result in the *exact* same behaviour as if you typed
it in at the lilo prompt and the driver was compiled into the kernel
instead of being a module. The reason for the single quote is so that
the shell won't try to interpret anything in the line, such as {.
Insmod assumes any options starting with a letter instead of a number
is a character string (which is what we want) and by switching all of
the commas to periods, insmod won't interpret this as more than one
string and write junk into our binary image. I consider it a bug in
the insmod program that even if you wrap your string in quotes (quotes
that pass the shell mind you and that insmod sees) it still treates
a comma inside of those quotes as starting a new variable, resulting
in memory scribbles if you don't switch the commas to periods.
Kernel Compile options
------------------------------
The various kernel compile time options for this driver are now fairly
well documented in the file Documentation/Configure.help. In order to
see this documentation, you need to use one of the advanced configuration
programs (menuconfig and xconfig). If you are using the "make menuconfig"
method of configuring your kernel, then you would simply highlight the
option in question and hit the ? key. If you are using the "make xconfig"
method of configuring your kernel, then simply click on the help button
next to the option you have questions about. The help information from
the Configure.help file will then get automatically displayed.
/proc support
------------------------------
The /proc support for the AIC7xxx can be found in the /proc/scsi/aic7xxx/
directory. That directory contains a file for each SCSI controller in
the system. Each file presents the current configuration and transfer
statistics (enabled with #define in aic7xxx.c) for each controller.
Thanks to Michael Neuffer for his upper-level SCSI help, and
Matthew Jacob for statistics support.
Debugging the driver
------------------------------
Should you have problems with this driver, and would like some help in
getting them solved, there are a couple debugging items built into
the driver to facilitate getting the needed information from the system.
In general, I need a complete description of the problem, with as many
logs as possible concerning what happens. To help with this, there is
a command option aic7xxx=panic_on_abort. This option, when set, forces
the driver to panic the kernel on the first SCSI abort issued by the
mid level SCSI code. If your system is going to reset loops and you
can't read the screen, then this is what you need. Not only will it
stop the system, but it also prints out a large amount of state
information in the process. Second, if you specify the option
"aic7xxx=verbose:0x1ffff", the system will print out *SOOOO* much
information as it runs that you won't be able to see anything.
However, this can actually be very useful if your machine simply
locks up when trying to boot, since it will pin-point what was last
happening (in regards to the aic7xxx driver) immediately prior to
the lockup. This is really only useful if your machine simply can
not boot up successfully. If you can get your machine to run, then
this will produce far too much information.

config AIC79XX_CMDS_PER_DEVICE
int "Maximum number of TCQ commands per device"
depends on SCSI_AIC79XX
default "32"
---help---
Specify the number of commands you would like to allocate per SCSI
device when Tagged Command Queueing (TCQ) is enabled on that device.
This is an upper bound value for the number of tagged transactions
to be used for any device. The aic7xxx driver will automatically
vary this number based on device behavior. For devices with a
fixed maximum, the driver will eventually lock to this maximum
and display a console message inidicating this value.
Due to resource allocation issues in the Linux SCSI mid-layer, using
a high number of commands per device may result in memory allocation
failures when many devices are attached to the system. For this reason,
the default is set to 32. Higher values may result in higer performance
on some devices. The upper bound is 253. 0 disables tagged queueing.
Per device tag depth can be controlled via the kernel command line
"tag_info" option. See drivers/scsi/aic7xxx/README.aic79xx
