where the console is, because that is correct if, for example, you
boot with the diag/norm switch set for diagnostics and the EEPROM
is set for keyboard/display.
* Update arch/mips/mips/cpu_exec.c to include MI exec_elf.h header,
and to use the MI interface exec_elf_makecmds().
* Replace arch/mips/mips/elf.c (Ted Lemon's elf code) with
a version of Christos's MI elf exec code, munged to support demand paging
and mips shared libraries.
Show proper inquiry data when version >= 1, not <= 1 (SCSI-2 devices
now display their inquiry infor).
Correct transfer length passed to dk_unbusy (b_resid hasn't been
updated yet).
* Eliminate the #ifdef DS5000 and kernel config option DS5000 altogether.
option DS5000 was a hangover from 4.4bsd/pmax; it's never been clear
if it means "support for DS5000/200" or "support for any TC machine".
This implictly fixes pr 1828.
* Use the "tc.h" and NTC generated by config for a "tc? at mainbus"
where appropriate, intsead of #ifdef DS5000.
* Canonicalize the spelling of kernel options that enable support
for particular models. Use
DS5000_25 for the Personal Decstation aka MAXINE aka KN02-ca
DS5000_100 for the 5000/1xx series aka KMIN aka KN02-ba
DS5000_200 for the 5000/200 aka 3MAX aka KN02
DS500_240 for the 5000/240 aka 3MAXPLUS aka KN03
and change DS_5000_xxx to DS5000_xxx everywhere.
* Wrap the interrupt handlers for each model in the appropriate #ifdef,
instead of wrapping all of them with "#ifdef DS5000".
* Wrap the TC autoconfig for each model in the appropriate #ifdef.
* Eliminate the #ifdef DS5000 and kernel config option DS5000 altogether.

#define so that ifr_mtu accesses that. MTU shouldn't be overloaded
with ifr_metric, if only for clarity. Adding an MTU field to the
union hurts nothing (in fact, does not actually _change_ generated
code), and does improve clarity.
works) for my machines and now-nonexistent test machines. Clean up
options in existing config files so that they're more consistent. Add
more units of various pseudo-devices to several.
For these CPU's, you have to use the ptest operation to search the mmu
tables in order to decide whether it is a real bus error or just a
page fault or write protection violation.
Our old code assumed user space always when calling ptest, and
erroneously assumed the BUSERR bit in the ptest output (mmusr
register) is the only indication for bus errors to check.
In fact, we have to follow a multistage decision tree to decide. 68060
CPUs are much easier to handle correctly.
Since linux binaries are (mostly) always compiled with gcc, look for
the gcc signature in the .comment section header: "\0 GCC: (GNU) ".
I've changed the probe order in kern/exec_elf.c to probe for linux ELF
binaries first and fall back to SVR4 binaries. This makes statically
linked binaries work for both linux and svr4. Note that gcc-compiled
svr4 binaries, still contain the operating system signature first and
then the GCC signature, so there is no conflict. Yes this is a hack.
and free some space by calling m_reclaim(). Also, log the "mb_map full"
error message (at most) every 60-seconds. The old code would log it
once over the lifetime of the system, but that's not a useful diagnostic.
(More useful is the new behaviour, which roughly indicates how often
periods of heavy load occur, without spamming the console and system
logs with messages.)
Right now, this code just panic()s (same as kmem_malloc() used to do
before, but different message), but in the future it should be modified
to try to reclaim wasted memory.
automatic array rather than an array allocated with alloca().
(This was the only use of alloca() in the kernel, and it wasn't
necessary or consistent with the way other functions in this file
work.)
This is a bit of a hack, as-is, since there's a lot of code that's
outright duplicated between the various files and because it doesn't
support detection of a network device as the root device. The
latter's not a problem yet, because NetBSD/Alpha can't load the kernel
from the network to begin with.
structure and 'aux', right before ca_attach is called for the
newly-attached device. This allows the alpha port to do root device
autodetection without modifying every bus and device driver which could
be in the 'boot path.' In the long run, it may make sense to make
this machine-independent.
an extended header is present i.e. don't assume an extended header as
however unlikely there could be a podule that doesn't have one.
Calculate an absolute address for the podule's interrupt mask rather
than leaving it relative to the base address of the podule.
If the interrupt status pointers are not present or are zero then
used the default bits as specified in the podule specification to
determine if the podule is interrupting.

Fill out the ih_maskaddr and ih_maskbits fields in the interrupt handler

if the handler should be called.

back on timer 1 interrupts if none is specified.
Only set up timer 1 is the driver is using timer 1 interrupts.
Don't claim the interrupt but allow them to be passed on to other
handlers.
Fixed the handling of IPL_NONE.
Debugged support for interrupt chaining.
Fill out the intrnames array with the name of the interrupt handler
currently at the head of the chain.
Guarded several sanity checks with #ifdef DIAGNOSTIC.
