I just released sym-2.1.0 driver, that, according to my personnal QA
plan :-), is the first Beta-release of this major driver version.
People interested in either using or just trying it can found the
reference tarball at the following URL:
ftp://ftp.tux.org/roudier/drivers/portable/sym-2.1.x/sym-2.1.0-20001230.tar.gz
This driver replaces functionnaly both sym53c8xx and ncr53c8xx.
It is in fact the FreeBSD sym driver that got portable and that, for now,
also supports Linux.
The driver reference sources layout is the following:
Common:
sym_conf.h sym_defs.h sym_fw.c sym_fw.h
sym_fw1.h sym_fw2.h sym_hipd.c sym_hipd.h
sym_malloc.c sym_misc.h sym_nvram.c
FreeBSD:
sym_glue.c sym_glue.h
Linux:
sym53c8xx.h sym_glue.c sym_glue.h
All the files can also be clicked/clipped :) individually from the
the following directory:
ftp://ftp.tux.org/roudier/drivers/portable/sym-2.1.x/current/
Given the genealogy of this driver, I have decided to maintain a high
level of compatibility with the sym53c8xx driver under Linux.
But, due to the number of sources files (14 under Linux), the driver
sources will now own a separate directory instead of being dropped in
the huge drivers/scsi/ directory.
The installation procedure supplied in the tarball moves the files to:
/usr/linux/drivers/scsi/sym53c8xx/
As a result, a tiny patch is needed for the related kernel files to
be aware of the new driver files location. And, as I have limited
time, only patches for 2.2.16, 2.2.17 and 2.2.18 are supplied for now.
People who will succeed installing the driver on other Linux kernel
releases, especially recent ones, can send me the corresponding tiny
kernel patch. Btw, this driver does not support Linux-2.0.X kernels.
The major improvements against sym53c8xx driver can be summarized
as follows:
- Don't use the scsi_obsolete interface anymore.
I could word it as 'use the new error handling interface', but the best
advantage, in my opinion, is that driver entry points are not called
recursively as does the old scsi code.
- Support for the entire NCR/SYMBIOS/LSILOGIC 53C[8XX|1010] in a single
driver without significant bloat of the object code.
The driver with all options enabled is about 73K not stripped and 59K
stripped under Linux-2.2.18.
- Refining of a couple of work-arounds that let me claim that the driver
supports the best possible all chips of all revisions, even very early
revisions of recent chips.
I am highly interested in receiving reports, either success or problem,
about this driver version, especially when the driver is tried on non Intel
IA32 platforms.
