908cdfe4e3 Add scsibus entry points to the cdevsw[]. 1998-10-10 02:00:49 +00:00
thorpej
29d472f53d Garbage-collect the open_target_lu and close_target_lu entry points from 
struct scsipi_adapter; they were not used.

Add a scsipi_ioctl entry point to struct scsipi_adapter.  This will be
used to issue ioctl commands to the host adapters.

Inspired by PR #6090, from Matt Jacob.

fcb0203141 First-cut at code to spin up secondary processors on a multiprocessor 
Alpha system, conditional on MULTIPROCESSOR.

NOTE: This does not yet work completely.  The secondary CPU begins the
boot process, but never makes it into the cpu spinup trampoline.  This
is merely a snapshot of a work-in-progress.

5b01d45ac4 Add a `-b #' option and logic for locating the secondary boot image via 
an absolute block address. It's cheating, as the motivation is support for
the libsa ustar tfs `filesystem' and the solution symmetrical to ufs and
cd9660 would have been to teach installboot about tfs. However, it still
would have been different as you can't mount a tfs with the kernel, and
this option gets possibly useful support for any contiguous format, even
completely raw boot images.

no longer running on the dead proc's vmspace and stack).
