SPARC vs. the MPSAFE TTY layer

[Ed Schouten]

Hello SPARC hackers,

Last week I sent this message to some of the FreeBSD lists, to discuss
my work on the new TTY layer I'm working on. The entire message is
available at:

There are actually two things which should be of interest to the SPARC
people:

- The Sun4V console driver does not compile anymore. It needs some work
  to get it back to a usable state. I don't own a Sun4V machine, which
  means I can't fix it.

- The SPARC64 ofw_console(4) driver has been ported, but for some reason
  there doesn't seem to be such a device on my U5. I don't have the U5
  anymore (I temporarily borrowed the U5 at the office). I would really
  like it if someone would test this driver on his/her hardware.

- Syscons already works on sparc64. uart(4) should also work, but I
  didn't really test it thoroughly.

I would really appreciate it if people would be willing to test my
MPSAFE TTY patchset. It would be nice if I could integrate this in a
couple of months. Thanks!
