* message buffer initialisation:
- change the buffer size to 8192 on all platforms
- don't assume the buffer is always located at physical address 0
- drop the SUN4 hack that left first half of the page unused;
I believe this is no longer necessary, since the msgbuf
data structure is duely sanity-checked before use in initmsgbuf().
structure. While this comes with the cost of having to search the
`vm_physmem' array every time need to find a PV entry corresponing to
some physical address, we gain the flexibility needed to support
arbitrary non-contiguous ranges of physical memory addresses.
Also, eliminate the need to sort the memory address ranges as presented
by the machine's PROM, and the requirement that physical memory starts
at address 0 (when possible).
Move the pointer to the current user trapframe from struct mdproc to struct
pcb (as on arm26). Only tested by compiling kernels on arm32 and
hpcarm (dnard seems to be incomplete anyway). Someone should try running one.
- only load rc.conf if $_rc_conf_loaded is not set
- use case instead of if for various string comparisons
- print the date at the start of the boot as well as at the end
- if $rc_fast_and_loose is set, always run the rc.d scripts in the
current shell rather than in a subshell. this is not on by default
because it's potentially dangerous (a rogue command could terminate
the boot), but it is provided as an optional speedup for people
with slow machines that have an expensive fork
to last time.
It turns out that in fact, sparc64 was *not* working. There is a discussion
within the tech-kern@netbsd.org mail list as of just prior to this date
that contains the details.
Suffice to say that for sparc64 we have to add back in the usage
of BUS_DMA_COHERENT again to the call to bus_dmamap_load_raw. PK
added the usage of bus_dmamap_load_raw- which agrees with the
man page description of it- but now does not match what the
original BusDma author seems to think it's supposed to do.
While we're at it, do a specific set of steps for setting up and,
if necessary, tearing down, mailbox dma mappings.
