CVS commit: src/sys/arch/hp300



Module Name:    src
Committed By:   thorpej
Date:           Tue Jan 16 07:07:00 UTC 2024

Modified Files:
        src/sys/arch/hp300/dev: dio.c dma.c dmavar.h
        src/sys/arch/hp300/hp300: autoconf.c
        src/sys/arch/hp300/include: intr.h

Log Message:
Fix computation of the appropriate auto-vector interrupt level to use
for the DMA controller by tracking all of the DIO devices that have
"ISRPRI_BIO" interrupt handlers, and finding the highest auto-vector
level among them and informing the DMA controller.

Previously, in a post-flattening world, the DMA controller was always
told to interrupt at lev5, which is fine I guess although definitely not
ideal, but would not work on aaaancient HP320 Rev A DMA boards.  To that
effect, print a warning if a Rev B DMA board ends up at ipl != 3 (we can't
differentiate between a Rev A and a Rev B board).
