If you say Y here, no logging output will appear by default, but you can enable logging by saying Y to "/proc file system support" and "Sysctl support" below and executing the command echo <bitmask> > /proc/sys/dev/scsi/logging_level where <bitmask> is a four byte value representing the logging type and logging level for each type of logging selected. There are a number of logging types and you can find them in the source at <file:drivers/scsi/scsi_logging.h>. The logging levels are also described in that file and they determine the verbosity of the logging for each logging type. If you say N here, it may be harder to track down some types of SCSI problems. If you say Y here your kernel will be somewhat larger, but there should be no noticeable performance impact as long as you have logging turned off. config SCSI_SCAN_ASYNC bool "Asynchronous SCSI scanning" depends on SCSI help The SCSI subsystem can probe for devices while the rest of the system continues booting, and even probe devices on different busses in parallel, leading to a significant speed-up.

This option forces a small delay (1.0 usec to be exact) after changing the control register to let things settle out. Enabling this option may result in a big drop in performance but some very old parallel ports (found in 386 vintage machines) will not work properly.

It also supports the subset of LSI53C10XX Ultra-160 controllers that are based on the SYM53C8XX SCRIPTS language. It does not support LSI53C10XX Ultra-320 PCI-X SCSI controllers; you need to use the Fusion MPT driver for that. Please read <file:Documentation/scsi/sym53c8xx_2.rst> for more information. config SCSI_SYM53C8XX_DMA_ADDRESSING_MODE int "DMA addressing mode" depends on SCSI_SYM53C8XX_2 default "1" help This option only applies to PCI-SCSI chips that are PCI DAC capable (875A, 895A, 896, 1010-33, 1010-66, 1000). When set to 0, the driver will program the chip to only perform 32-bit DMA. When set to 1, the chip will be able to perform DMA to addresses up to 1TB. When set to 2, the driver supports the full 64-bit DMA address range, but can only address 16 segments of 4 GB each. This limits the total addressable range to 64 GB. Most machines with less than 4GB of memory should use a setting of 0 for best performance. If your machine has 4GB of memory or more, you should set this option to 1 (the default). The still experimental value 2 (64 bit DMA addressing with 16 x 4GB segments limitation) can be used on systems that require PCI address bits past bit 39 to be set for the addressing of memory using PCI DAC cycles. config SCSI_SYM53C8XX_DEFAULT_TAGS int "Default tagged command queue depth" depends on SCSI_SYM53C8XX_2 default "16" help This is the default value of the command queue depth the driver will announce to the generic SCSI layer for devices that support tagged command queueing. This value can be changed from the boot command line. This is a soft limit that cannot exceed CONFIG_SCSI_SYM53C8XX_MAX_TAGS. config SCSI_SYM53C8XX_MAX_TAGS int "Maximum number of queued commands" depends on SCSI_SYM53C8XX_2 default "64" help This option allows you to specify the maximum number of commands that can be queued to any device, when tagged command queuing is possible. The driver supports up to 256 queued commands per device. This value is used as a compiled-in hard limit. config SCSI_SYM53C8XX_MMIO bool "Use memory mapped IO" depends on SCSI_SYM53C8XX_2 default y help Memory mapped IO is faster than Port IO.

Performance impact is minimal. Trace can be dumped using /sys/bus/class/scsi_host/hostXX/trace. config SCSI_IPR_DUMP bool "enable adapter dump support" depends on SCSI_IPR default y help If you say Y here, the driver will support adapter crash dump. If you enable this support, the iprdump daemon can be used to capture adapter failure analysis information. config SCSI_ZALON tristate "Zalon SCSI support" depends on GSC && SCSI select SCSI_SPI_ATTRS help The Zalon is a GSC/HSC bus interface chip that sits between the PA-RISC processor and the NCR 53c720 SCSI controller on C100, C110, J200, J210 and some D, K & R-class machines. It's also used on the add-in Bluefish, Barracuda & Shrike SCSI cards. Say Y here if you have one of these machines or cards. config SCSI_NCR53C8XX_DEFAULT_TAGS int "default tagged command queue depth" depends on SCSI_ZALON default "8" help "Tagged command queuing" is a feature of SCSI-2 which improves performance: the host adapter can send several SCSI commands to a device's queue even if previous commands haven't finished yet. Because the device is intelligent, it can optimize its operations (like head positioning) based on its own request queue. Some SCSI devices don't implement this properly; if you want to disable this feature, enter 0 or 1 here (it doesn't matter which). The default value is 8 and should be supported by most hard disks. This value can be overridden from the boot command line using the 'tags' option as follows (example): 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to 4, set queue depth to 16 for target 2 and target 3 on controller 0 and set queue depth to 10 for target 0 / lun 2 on controller 1. The normal answer therefore is to go with the default 8 and to use a boot command line option for devices that need to use a different command queue depth. There is no safe option other than using good SCSI devices. config SCSI_NCR53C8XX_MAX_TAGS int "maximum number of queued commands" depends on SCSI_ZALON default "32" help This option allows you to specify the maximum number of commands that can be queued to any device, when tagged command queuing is possible. The default value is 32. Minimum is 2, maximum is 64. Modern hard disks are able to support 64 tags and even more, but do not seem to be faster when more than 32 tags are being used. So, the normal answer here is to go with the default value 32 unless you are using very large hard disks with large cache (>= 1 MB) that are able to take advantage of more than 32 tagged commands. There is no safe option and the default answer is recommended. config SCSI_NCR53C8XX_SYNC int "synchronous transfers frequency in MHz" depends on SCSI_ZALON default "20" help The SCSI Parallel Interface-2 Standard defines 5 classes of transfer rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers are respectively the maximum data transfer rates in mega-transfers per second for each class. For example, a FAST-20 Wide 16 device is able to transfer data at 20 million 16 bit packets per second for a total rate of 40 MB/s. You may specify 0 if you want to only use asynchronous data transfers. This is the safest and slowest option. Otherwise, specify a value between 5 and 80, depending on the capability of your SCSI controller. The higher the number, the faster the data transfer. Note that 80 should normally be ok since the driver decreases the value automatically according to the controller's capabilities. Your answer to this question is ignored for controllers with NVRAM, since the driver will get this information from the user set-up. It also can be overridden using a boot setup option, as follows (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate for FAST-20 synchronous data transfer (20 mega-transfers per second). The normal answer therefore is not to go with the default but to select the maximum value 80 allowing the driver to use the maximum value supported by each controller. If this causes problems with your SCSI devices, you should come back and decrease the value. There is no safe option other than using good cabling, right terminations and SCSI conformant devices. config SCSI_NCR53C8XX_NO_DISCONNECT bool "not allow targets to disconnect" depends on SCSI_ZALON && SCSI_NCR53C8XX_DEFAULT_TAGS=0 help This option is only provided for safety if you suspect some SCSI device of yours to not support properly the target-disconnect feature. In that case, you would say Y here. In general however, to not allow targets to disconnect is not reasonable if there is more than 1 device on a SCSI bus. The normal answer therefore is N. config SCSI_QLOGIC_FAS tristate "Qlogic FAS SCSI support" depends on ISA && SCSI help This is a driver for the ISA, VLB, and PCMCIA versions of the Qlogic FastSCSI! cards as well as any other card based on the FASXX chip (including the Control Concepts SCSI/IDE/SIO/PIO/FDC cards).
