- Allow BUGCHK and BPT instruction faults in kernel mode if DDB is enabled,
since they are used to invoke the debugger.
- Add a comment about how we'd like to invoke DDB on a trap panic condition,
in a perfect world.
pointer to boot program's bootinfo structure. If the bootinfo magic
matches, save a copy of the bootinfo structure, and use it to determine
booted kernel name, the boot flags, and the location of the kernel symbol
table. If the magic number does not match, revert to the old method
of finding this information (sans symbol table info).
- Add some additonal DDB glue.
was sent to developers, but will eventually become a man page or
something), i noticed a few in various names:
(1) _map and _alloc should take a flags argument, rather than a
'cacheable' boolean.
(2) BUS_BARRIER_* flags should be BUS_SPACE_BARRIER_*.
(3) bus_space_copy_* should be bus_space_copy_region_* for consistency
with other region ops.
Fix all of these (in a backward-compatible way, at least for now). Redefine
internal usees of those names to use the new names. Also, while at it,
clean up the copy functions (remove unnecessary variables) and make sure
that they and other functions conform to the spec.
don't assume that the names/values to be put into defines in assym.h
start with the first .ascii in the assembler file; look for the array
start symbol, instead.
* Move clockvar.h (header file for generic clock code) to sys/dev/dec.
* Move if_le_dec.c with DEC padded LANCE-dma (pmax/pmax, ioasic, vax 3400)
to sys/dev/dec. Remove from sys/dev/tc.
* Declare attribute le_dec_subr in /sys/dev/dec/files.dec,
use if_le_dec.c when it's defined.
* Move IOCTL asic declaration from pmax and Alpha MD machine
files to sys/dev/tc/files.tc.
* move TurboChannel and ioasic if_le attachments from pmax and Alpha machine
config files to /sys/dev/tc/files.tc. Add le_dec_subr attribute.
* Add if_le_dec attribute to if_le_ibus (pmax ds3100 pmax) LANCE attachment.
into the 'argument variables' section.
* define variables for CPP and SIZE, defaulting to cpp and size, respectively.
* kill HOSTED_C*, since it's no longer used.
* use ${SIZE} rather than using 'size' directly, so it can be overridden for
cross-builds.
* generate assym.h via assym.s and an awk script.

present. Decode, but don't bother displaying, the power consumption
information for each PCI slot.
behaviour of splhigh() was changed. The new behaviour raised the level to
IPL_HIGH if it was lower, but left it alone if the same or higher. Apparently
the firmware transfers to NetBSD with all interrupts blocked, or something
else blocks all interrupts (including machine checks) before the code
is really started. This meant that machine checks were blocked during
device probes, leading to false device probes _and_ an unexpected (and
therefore fatal) machine check at the spl0() after autoconfiguration.
(1) it was using 'max', and some functions use a variable
of that name (*sigh*), and
(2) that makes it easier to be a bit trickier, and only call
swpipl if changing the IPL.
compliation without DEBUG and/or DIAGNOSTIC happens without errors.
Note that all such initializations in the Alpha port are marked with "XXX
gcc -Wuninitialized". As far as I'm concerned, the one or two times
-Wuninitialized has saved me from problems are worth the (very minor) cost
involved with the initializations, esp. if it's noted why the
initializations are done. This was prompted by PR#3690, from Ted Lemon.

slightly modified to allow wildcarded offsets.
- Blow away the cf->cf_unit check in sccmatch(); it's bogus.
Remove esp FLUSH when residual bytes are present in FIFO, the ncr53c9x
driver will flush when necessary. Doing the FLUSH here interferes
with DMA-enabled target selection.
It is configured (in config files) as 'awdc'/'awd', but shows up as
'wdc'/'wd', so that a minimal amount of code had to be modified to make
the name change work. This is only intended to be temporary, anyway.
(1) object code can be shared (where the hardware makes that possible), and
(2) so that the file names better describe the systems which use them. (the
pci_swiz* files are for machines whose PCI interfaces require address
"swizzling." Later, there will be probably be other sets, e.g. pci_bwx*
for machines whose chipsets can easily deal with the Alpha BWX extensions
when doing device accesses.)
arguments, so that a device can tell if its memory and I/O spaces are
enabled. The flags are cleared, depending on the contents of devices CSR
registers, in the machine-independent PCI bus code.
define CPU options and FIX_UNALIGNED_VAX_FP as header-generating options.
add pci_swiz_*_common.c when appropriate.
clean up a bit and sort more carefully.
This can be disabled (to save a bit of space) with the NO_KERNEL_RCSIDS
options, which is present but commented out in the ALPHA config file.
In ELF-format kernels, these strings are present in the kernel binary but
are not loaded into memory. (In ECOFF-format kernels, there's no easy way
to keep them from being loaded, so they _are_ loaded into memory.)
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.
For the detailed change history, look at the commit log entries for
the is-newarp branch.
