First of all, sorry about copying the whole message again in
my reply.
Second, rev. 1.22 of ppi.c already contains the check for
bus alloc failing. Thanks for the patch though.
On the shareable flag. It doesn't hurt to add it. And if it
makes it work for you, just leave it there, it's a good
idea. I won't add it for the general case, as with ISA
hardware it more often breaks than that it is valid
solution.
On the header files: The best solution would be to copy
those to /usr/include/sys/dev/ppbus during make world where
they belong (like the /sys/dev/usb ones), but I can't be
bothered at the moment.
Thanks for the PR!
Nick
