Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

---help---
This driver supports all of Adaptec's Fast through Ultra 160 PCI
based SCSI controllers as well as the aic7770 based EISA and VLB
SCSI controllers (the 274x and 284x series). For AAA and ARO based
configurations, only SCSI functionality is provided.
To compile this driver as a module, choose M here: the
module will be called aic7xxx.

---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

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 bus settle delay following all error recovery actions is
dictated by the SCSI layer and is not affected by this value.

This option should only be enabled if you are modifying the firmware
source to the aic7xxx driver and wish to have the generated firmware
include files updated during a normal kernel build. The assembler
for the firmware requires lex and yacc or their equivalents, as well
as the db v1 library. You may have to install additional packages
or modify the assembler Makefile or the files it includes if your
build environment is different than that of the author.
