DESCRIPTION:
- This is the Linux low-level SCSI driver for Adaptec AHA-1520/1522
- SCSI host adapters.
+ This is the Linux low-level SCSI driver for Adaptec AHA-1520/1522 SCSI
+ host adapters.
- PER-DEFINE CONFIGURABLE OPTIONS:
+ CONFIGURATION ARGUMENTS:
- AUTOCONF : use configuration the controller reports (only 152x)
- IRQ : override interrupt channel (9,10,11 or 12) (default 11)
- SCSI_ID : override scsiid of AIC-6260 (0-7) (default 7)
- RECONNECT : override target dis-/reconnection/multiple outstanding commands (default on)
- PARITY : override parity check (default on)
- SKIP_BIOSTEST : Don't test for BIOS signature (AHA-1510 or disabled BIOS)
- PORTBASE : Force port base. Don't try to probe
+ IOPORT base io address (0x340/0x140)
+ IRQ interrupt level (9-12; default 11)
+ SCSI_ID scsi id of controller (0-7; default 7)
+ RECONNECT allow targets to disconnect from the bus (0/1; default 1 [on])
+ PARITY enable parity checking (0/1; default 1 [on])
+ SYNCHRONOUS enable synchronous transfers (0/1; default 0 [off])
+ (NOT WORKING YET)
+ DELAY: bus reset delay (default 100)
+ EXT_TRANS: enable extended translation (0/1: default 0 [off])
+ (see NOTES below)
+
+ COMPILE TIME CONFIGURATION (put into AHA152X in drivers/scsi/Makefile):
+
+ -DAUTOCONF
+ use configuration the controller reports (AHA-152x only)
+
+ -DSKIP_BIOSTEST
+ Don't test for BIOS signature (AHA-1510 or disabled BIOS)
+
+ -DSETUP0="{ IOPORT, IRQ, SCSI_ID, RECONNECT, PARITY, SYNCHRONOUS, DELAY, EXT_TRANS }"
+ override for the first controller
+
+ -DSETUP1="{ IOPORT, IRQ, SCSI_ID, RECONNECT, PARITY, SYNCHRONOUS, DELAY, EXT_TRANS }"
+ override for the second controller
LILO COMMAND LINE OPTIONS:
- aha152x=<PORTBASE>[,<IRQ>[,<SCSI-ID>[,<RECONNECT>[,<PARITY>]]]]
+ aha152x=<IOPORT>[,<IRQ>[,<SCSI-ID>[,<RECONNECT>[,<PARITY>[,<SYNCHRONOUS>[,<DELAY> [,<EXT_TRANS]]]]]]]
The normal configuration can be overridden by specifying a command line.
When you do this, the BIOS test is skipped. Entered values have to be
- valid (known). Don't use values that aren't support under normal operation.
- If you think that you need other values: contact me.
+ valid (known). Don't use values that aren't supported under normal
+ operation. If you think that you need other values: contact me.
+ For two controllers use the aha152x statement twice.
+
+
+ SYMBOLS FOR MODULE CONFIGURATION:
+
+ aha152x=IOPORT,IRQ,SCSI_ID,RECONNECT,PARITY,SYNCHRONOUS,DELAY,EXT_TRANS
+ configuration override of first controller
+
+
+ aha152x1=IOPORT,IRQ,SCSI_ID,RECONNECT,PARITY,SYNCHRONOUS,DELAY,EXT_TRANS
+ configuration override of second controller
+
+
+ NOTES ON EXT_TRANS:
+
+ SCSI uses block numbers to address blocks/sectors on a device.
+ The BIOS uses a cylinder/head/sector addressing scheme (C/H/S)
+ scheme instead. DOS expects a BIOS or driver that understands this
+ C/H/S addressing.
+
+ The number of cylinders/heads/sectors is called geometry and is required
+ as base for requests in C/H/S adressing. SCSI only knows about the
+ total capacity of disks in blocks (sectors).
+
+ Therefore the SCSI BIOS/DOS driver has to calculate a logical/virtual
+ geometry just to be able to support that addressing scheme. The geometry
+ returned by the SCSI BIOS is a pure calculation and has nothing to
+ do with the real/physical geometry of the disk (which is usually
+ irrelevant anyway).
+
+ Basically this has no impact at all on Linux, because it also uses block
+ instead of C/H/S addressing. Unfortunately C/H/S addressing is also used
+ in the partition table and therefore every operating system has to know
+ the right geometry to be able to interpret it.
+
+ Moreover there are certain limitations to the C/H/S addressing scheme,
+ namely the address space is limited to upto 255 heads, upto 63 sectors
+ and a maximum of 1023 cylinders.
+
+ The AHA-1522 BIOS calculates the geometry by fixing the number of heads
+ to 64, the number of sectors to 32 and by calculating the number of
+ cylinders by dividing the capacity reported by the disk by 64*32 (1 MB).
+ This is considered to be the default translation.
+
+ With respect to the limit of 1023 cylinders using C/H/S you can only
+ address the first GB of your disk in the partition table. Therefore
+ BIOSes of some newer controllers based on the AIC-6260/6360 support
+ extended translation. This means that the BIOS uses 255 for heads,
+ 63 for sectors and then divides the capacity of the disk by 255*63
+ (about 8 MB), as soon it sees a disk greater than 1 GB. That results
+ in a maximum of about 8 GB adressable diskspace in the partition table
+ (but there are already bigger disks out there today).
+
+ To make it even more complicated the translation mode might/might
+ not be configurable in certain BIOS setups.
+
+ This driver does some more or less failsafe guessing to get the
+ geometry right in most cases:
+
+ - for disks<1GB: use default translation (C/32/64)
+ - for disks>1GB:
+ - take current geometry from the partition table
+ (using scsicam_bios_param and accept only `valid' geometries,
+ ie. either (C/32/64) or (C/63/255)). This can be extended
+ translation even if it's not enabled in the driver.
+ - if that fails, take extended translation if enabled by override,
+ kernel or module parameter, otherwise take default translation and
+ ask the user for verification. This might on not yet partitioned
+ disks or
