It seems that PA 2.0 is a "linear" extension of PA 1.1. It is possible to run 32 bit binaries (including the kernel) on PA 2.0 machines when the PSW W bit is 0. But, obviously, the TLB and everything related is extended to support the 64 bit physical addres space. So this is somthing for you when you are interrested in some quite low level, machine dependent virtual memory management work. This is nothing you do in an afternoon.

There are some other things like wscons to do, I still didn't get the "energy" and time to dig into the longjmp / __sigreturn14 issue, gdb for hppa / hp700 is broken, some MD pthread bits are missing... and an other developer was looking at the ld.elf_so problem. BTW: Thanks to Jens Konrad. He gave me K100 so I am now able to work on PA7200 support. -- tschüß, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/
