Dennis;
Right forum but this listserver is geared to Mainframe programmers. The
last place I saw any information was in the AIX "How write device driver".
I thought that this was on AIX 3.2 specific machine. Subsequent releases of
the manuals were not availble at the time was doing work in that area. I
think you can find a little detail on IBM's FTP server and some source
code as well. P-Series assembler is rather a bit of specialized coding,
I'd suggest writing everything in C first and , them examine the assembler
listing if you have specific doubts about what being performed on behalf of
the compiler. Usually C compilers are very efficient at machine code
generation , "it just so damm ugly" to read without a COFF guide.
Good luck.

Hi AIX gurus,
Developing an AIX driver, I need to split incoming frames headers and data
into separate buffers. Each frame consists of a 32 bytes header and 2 KB
data. Each exchange may consist of several frames. I want to direct the N
headers to a driver buffer and concatenate user's data to one larger
user's buffer. The question is how should I set the dio and d_iovec
structures for the d_map_list function call.
Thanks by advance.
Denis
