127

129	  writer software look at Cdrtools
130	  (<http://cdrtools.sourceforge.net/>)
131	  and for burning a "disk at once": CDRDAO
132	  (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high

184
185	  If you say Y here, no logging output will appear by default, but you
186	  can enable logging by saying Y to "/proc file system support" and
187	  "Sysctl support" below and executing the command
188
189	  echo <bitmask> > /proc/sys/dev/scsi/logging_level
190
191	  where <bitmask> is a four byte value representing the logging type
192	  and logging level for each type of logging selected.
193
194	  There are a number of logging types and you can find them in the
195	  source at <file:drivers/scsi/scsi_logging.h>. The logging levels
196	  are also described in that file and they determine the verbosity of
197	  the logging for each logging type.
198
199	  If you say N here, it may be harder to track down some types of SCSI
200	  problems. If you say Y here your kernel will be somewhat larger, but
201	  there should be no noticeable performance impact as long as you have

1036	  'tags' option as follows (example):
1037	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1038	  4, set queue depth to 16 for target 2 and target 3 on controller 0
1039	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1040
1041	  The normal answer therefore is to go with the default 8 and to use
1042	  a boot command line option for devices that need to use a different
1043	  command queue depth.
1044
1045	  There is no safe option other than using good SCSI devices.

1051	---help---
1052	  This option allows you to specify the maximum number of commands
1053	  that can be queued to any device, when tagged command queuing is
1054	  possible. The default value is 32. Minimum is 2, maximum is 64.
1055	  Modern hard disks are able to support 64 tags and even more, but
1056	  do not seem to be faster when more than 32 tags are being used.
1057
1058	  So, the normal answer here is to go with the default value 32 unless
1059	  you are using very large hard disks with large cache (>= 1 MB) that
1060	  are able to take advantage of more than 32 tagged commands.
1061

1068	---help---
1069	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1070	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1071	  are respectively the maximum data transfer rates in mega-transfers
1072	  per second for each class.  For example, a FAST-20 Wide 16 device is
1073	  able to transfer data at 20 million 16 bit packets per second for a
1074	  total rate of 40 MB/s.
1075
1076	  You may specify 0 if you want to only use asynchronous data
1077	  transfers. This is the safest and slowest option. Otherwise, specify
1078	  a value between 5 and 80, depending on the capability of your SCSI
1079	  controller.  The higher the number, the faster the data transfer.
1080	  Note that 80 should normally be ok since the driver decreases the
1081	  value automatically according to the controller's capabilities.
1082
1083	  Your answer to this question is ignored for controllers with NVRAM,
1084	  since the driver will get this information from the user set-up.  It
1085	  also can be overridden using a boot setup option, as follows
1086	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1087	  for FAST-20 synchronous data transfer (20 mega-transfers per
1088	  second).
1089
1090	  The normal answer therefore is not to go with the default but to
1091	  select the maximum value 80 allowing the driver to use the maximum
1092	  value supported by each controller. If this causes problems with
1093	  your SCSI devices, you should come back and decrease the value.
1094
1095	  There is no safe option other than using good cabling, right
1096	  terminations and SCSI conformant devices.
