This includes synchronous/asynchronous transfers, maximum synchronous negotiation rate, wide transfers, disconnection, the host adapter's SCSI ID. For systems that store non-volatile settings in a system specific manner rather than a serial eeprom directly connected to the aic7xxx controller, the .Tn BIOS must be enabled for the driver to access this information. This restriction applies to many chip-down motherboard configurations. .Pp Performance and feature sets vary throughout the aic7xxx product line. The following table provides a comparison of the different chips supported by the .Nm driver. Note that wide and twin channel features, although always supported by a particular chip, may be disabled in a particular motherboard or card design. .Bd -ragged -offset indent .Bl -column "aic7895CX" "MIPSX" "PCI/64X" "MaxSyncX" "MaxWidthX" "SCBsX" "2 3 4 5 6 7 8X" .It Em "Chip" Ta "MIPS" Ta "Bus" Ta "MaxSync" Ta "MaxWidth" Ta "SCBs" Ta "Features" .It "aic7770" Ta "10" Ta "VL" Ta "10MHz" Ta "16Bit" Ta "4" Ta "1" .It "aic7850" Ta "10" Ta "PCI/32" Ta "10MHz" Ta "8Bit" Ta "3" Ta "" .It "aic7860" Ta "10" Ta "PCI/32" Ta "20MHz" Ta "8Bit" Ta "3" Ta "" .It "aic7870" Ta "10" Ta "PCI/32" Ta "10MHz" Ta "16Bit" Ta "16" Ta "" .It "aic7880" Ta "10" Ta "PCI/32" Ta "20MHz" Ta "16Bit" Ta "16" Ta "" .It "aic7890" Ta "20" Ta "PCI/32" Ta "40MHz" Ta "16Bit" Ta "16" Ta "3 4 5 6 7 8" .It "aic7891" Ta "20" Ta "PCI/64" Ta "40MHz" Ta "16Bit" Ta "16" Ta "3 4 5 6 7 8" .It "aic7892" Ta "20" Ta "PCI/64" Ta "80MHz" Ta "16Bit" Ta "16" Ta "3 4 5 6 7 8" .It "aic7895" Ta "15" Ta "PCI/32" Ta "20MHz" Ta "16Bit" Ta "16" Ta "2 3 4 5" .It "aic7895C" Ta "15" Ta "PCI/32" Ta "20MHz" Ta "16Bit" Ta "16" Ta "2 3 4 5 8" .It "aic7896" Ta "20" Ta "PCI/32" Ta "40MHz" Ta "16Bit" Ta "16" Ta "2 3 4 5 6 7 8" .It "aic7897" Ta "20" Ta "PCI/64" Ta "40MHz" Ta "16Bit" Ta "16" Ta "2 3 4 5 6 7 8" .It "aic7899" Ta "20" Ta "PCI/64" Ta "80MHz" Ta "16Bit" Ta "16" Ta "2 3 4 5 6 7 8" .El .Pp .Bl -enum -compact .It Multiplexed Twin Channel Device - One controller servicing two busses. .It Multi-function Twin Channel Device - Two controllers on one chip. .It Command Channel Secondary DMA Engine - Allows scatter gather list and SCB prefetch. .It 64 Byte SCB Support - SCSI CDB is embedded in the SCB to eliminate an extra DMA. .It Block Move Instruction Support - Doubles the speed of certain sequencer operations. .It .Sq Bayonet style Scatter Gather Engine - Improves S/G prefetch performance. .It Queuing Registers - Allows queueing of new transactions without pausing the sequencer. .It Multiple Target IDs - Allows the controller to respond to selection as a target on multiple SCSI IDs. .El .Ed .Sh CONFIGURATION OPTIONS .Pp To allow PCI adapters to use memory mapped I/O if enabled: .Pp -.Cd options AHC_ALLOW_MEMIO +.Cd options AHC_ALLOW_MEMIO=(0 -- disabled, 1 -- enabled) .Bd -ragged -offset indent Memory mapped I/O is more efficient than the alternative, programmed I/O.

The SCB contains all of the information required by the controller to process a transaction. The chip feature table lists the number of SCBs that can be stored in on-chip memory. All chips with model numbers greater than or equal to 7870 allow for the on chip SCB space to be augmented with external SRAM up to a maximum of 255 SCBs. Very few Adaptec controller configurations have external SRAM. .Pp If external SRAM is not available, SCBs are a limited resource. Using the SCBs in a straight forward manner would only allow the driver to handle as many concurrent transactions as there are physical SCBs. To fully utilize the SCSI bus and the devices on it, requires much more concurrency. The solution to this problem is .Em SCB Paging , a concept similar to memory paging. SCB paging takes advantage of the fact that devices usually disconnect from the SCSI bus for long periods of time without talking to the controller. The SCBs for disconnected transactions are only of use to the controller when the transfer is resumed. When the host queues another transaction for the controller to execute, the controller firmware will use a free SCB if one is available. Otherwise, the state of the most recently disconnected (and therefore most likely to stay disconnected) SCB is saved, via dma, to host memory, and the local SCB reused to start the new transaction. This allows the controller to queue up to 255 transactions regardless of the amount of SCB space. Since the local SCB space serves as a cache for disconnected transactions, the more SCB space available, the less host bus traffic consumed saving and restoring SCB data. .Sh SEE ALSO .Xr ahd 4 , .Xr cd 4 , .Xr da 4 , .Xr sa 4 , .Xr scsi 4 .Sh HISTORY The .Nm driver appeared in .Fx 2.0 . .Sh AUTHORS The .Nm driver, the .Tn AIC7xxx sequencer-code assembler, and the firmware running on the aic7xxx chips was written by .An Justin T. Gibbs . .Sh BUGS Some Quantum drives (at least the Empire 2100 and 1080s) will not run on an .Tn AIC7870 Rev B in synchronous mode at 10MHz. Controllers with this problem have a 42 MHz clock crystal on them and run slightly above 10MHz. This confuses the drive and hangs the bus. Setting a maximum synchronous negotiation rate of 8MHz in the .Tn SCSI-Select utility will allow normal operation. .Pp Although the Ultra2 and Ultra160 products have sufficient instruction ram space to support both the initiator and target roles concurrently, this configuration is disabled in favor of allowing the target role to respond on multiple target ids. A method for configuring dual role mode should be provided. .Pp Tagged Queuing is not supported in target mode. .Pp Reselection in target mode fails to function correctly on all high voltage differential boards as shipped by Adaptec. Information on how to modify HVD board to work correctly in target mode is available from Adaptec. diff --git a/sys/dev/aic7xxx/ahc_pci.c b/sys/dev/aic7xxx/ahc_pci.c index 1f9cd33f9e00..8109a6714814 100644 --- a/sys/dev/aic7xxx/ahc_pci.c +++ b/sys/dev/aic7xxx/ahc_pci.c @@ -1,221 +1,221 @@ /*- * FreeBSD, PCI product support functions * * Copyright (c) 1995-2001 Justin T.
