[Linux-streams] LiS-2.12

Hello everybody,

LiS-2.12 has emerged from the land of Beta testing and is now available
on the Gcom FTP site.  Just connect your browser to http://www.gcom.com
and select Linux-->LiS to get to the LiS documentation.  Click the
Download button to get a copy.

The documentation goes into some detail about what is new in LiS-2.12.
The main thing is that it now uses all the CPUs aggressively on 2.4
kernels.  There is a queue runner process for each CPU.

LiS-2.12 also has more insulation between STREAMS drivers and kernel
functions.

Also, the base major number for STREAMS drivers has been moved to 240
for all kernel versions.  Hopefully the kernel guys will fix the 8-bit
major number problem for 2.6 and then we can get a permanent block of
majors assigned to LiS.

Driver writers will need to recompile in the context of LiS-2.12 include
files.  The resulting driver binaries can then be used on either 2.2 or
2.4 kernels provided that the drivers use the LiS abstractions of kernel
functions rather than calling kernel routines directly.

Some people have reported difficulties with SuSE 7.1 due to
incompatibilities between kernel configuration files and the kernel
binary that comes as the default kernel.  So if you are installing LiS
on that distribution be on the alert for problems.  You might have to
hack the LiS config.in file by hand to get some of the options such as
SMP and Mod-versions set correctly.
