The pre-compiled library(megaide_lib.o) is included. 
The object of the megaide driver is created by linking this library.
I believe that the source of the exhibited portion is
a portion except the algorithm of RAID.
These are efforts and the results of Atul and Manoj.

However, since the library of binary distribution is included,
I think that the kernel version which operates will be limited.
If there is the solution method of this problem,
please let me know.

Then the driver is not available under the terms of the GPL.... 
(and not compatible with the kernel license so inclusion is not possible)

And therefore should not any reference to the GPL in the other files. I
think this should be all or nothing.

Hi Haruo,
the library will stay closed source. The header files are only meant to make
it easier to compile for different kernel versions.

Thanks

Is it that the source code of megaide_lib.o should be opened?

I was told by people on another list that if any part is closed the
entire package will not be included in the kernel tree. So yes
negaide.lib.o should be open sourced or LSI should provide drivers to
linux users as well as any other platform that uses their hardware.

Correct.  Drivers must be 100% open source, or they are not included in 
Linux.

This is dictated by the GNU General Public License, under which all 
kernel code is licensed.

new driver

[Ken Schneider]

I have been sent the sources for the LSI LOGIC, Inc. Ultra ATA100 IDE raid 
controller as found on the mainboard of the HP ML330 computer. I requested 
information concerning the inclusion of the code into the kernel tree and 
have been informed that the source is open and can be included as stated in 
all of the .c and .h files.
Example:

 */

Having this code included will make the life of many people much easier in 
being able to use the raid function of the controller.

I have been able (with the help of people on the SuSE mailing list) to get the 
module compiled for the 2.4 kernel. As the 2.6 tree and compilation 
procedures have changed I can no longer get the module to compile, I am not a 
programmer as I know just enough about C to be dangerous.

Copies of the correspondence and the sources are available either from me or 
tech support at LSI Logic Corp. 

Any help in this matter would be appreciated. I am also willing to be a guinea 
pig for any testing of the module.

We're generally not including software raid as LLDD.  We'd be interested in
both drivers for the underlying ide controller (if not yet support by linux)
and a tool to setup the tables for device mapper.

btw, where is the source for the driver you're talking about?

and for 2.4 as ataraid driver; writing one is like a few hours of work
at most so do send a pointer to the source :)

Just to echo the others...

You need to add two drivers:

1) low-level hardware driver for this LSI hardware
2) software RAID driver

They are distinct and separate, when you're talking about software RAID.
