- Make data_abort_address() return the whole affected range, rather than
just one end.
- Don't rely on pmap_confess(). Instead, for LDM/STM, behave as if two faults
had occurred, one at each end of the range.
- Separate out fault handling into do_fault(), and call it from
data_abort_handler() (twice) and prefetch_abort_handler().
1: Cleanup of syscall() -- treat the arguments as an array of register_t
throughout. This saves a few casts, and generally makes seeing what's
going on easier.
2: Be a little more careful in the handling of data aborts on kernel
addresses: don't use the kernel's map unless the access was actually from
a kernel mode. This is how the arm32 data abort handler behaves.
- Use UVMHIST for debugging messages, rather than printf
- Rely on the caller of pmap_enter to tell us how to manipulate referenced/
modified bits in the kernel pmap.
[ Suggested by chs -- may need work on the rest of the kernel. ]
- Split third-stage initialisation out of pmap_create() into pmap_init2().
- Bug fix: when relocating pv_table, fix up all references to it as well.
- Bug fix: in pv_release(), if pulling up a pv_entry to the head of the
list, correct the reference from its pmap.
just get pmap_fault to shove them back in. Crude, but effective. Fix inspired
by Chuck Silvers.
This breaks pmap_confess, but it probably deserves to die.
XXX if you have libc after citrus locale import, please recompile libc,
and your applications that use mbstate_t (rather rare). really sorry
for the mess.

By default, they aren't used, since most cards seem to put the non-OS-dependent
stuff in the main chunk directory. i-cubed cards are a notable exception.
Issue Service_PreReset to get the hardware to a sane state.
Use *ShutDown to log off fileservers.
Use the correct arguments to Cache_Control.
Using Service_PreReset seems to have rendered the Podule_ReadID trick
unnecessary, so g/c it.

the command line, so we don't need to tokenize it first.
This makes it less than clear what file type BBBB should have, so let's not
make an issue of it.
rather than assigning to the whole field, set or clear individual flags,
which implies that the B_BUSY and B_INVAL flags will remain set.
this allows us to make the assertion in brelse() that B_BUSY is set,
which is the purpose of all this.
the UPC driver needs to know whether the system's got an IOEB in it.
The way this is implemented is a mess -- I need to get my mind round
autoconfiguration again.

* All of pmap_init is now deferred to the first call of pmap_create. This
allows us to allocate stuff dynamically using malloc.
* pv_table (which is needed before malloc is available) is temporarily
allocated using pmap_steal_memory in pmap_bootstrap, and then
re-allocated using malloc in pmap_create, with the old allocation being
given back to UVM. This should save some memory on small machines, but
the malloc overhead probably soaks it up.

to specify a minimum power-of-two alignment of the region.
How we ever got along without this for so long is beyond me.

Largely from Bill Sommerfeld, with some minor bug fixes and
machine-dependent code hacking from me.
as used on later arm26 system (A5000, A4, A3010, A3020, A4000).
What we have got:
...
upc0 at iobus0 base 0x010000: config state bb 87 1c 00 00
fdc at upc0 offset 0x3f4 not configured
wdc0 at upc0 offset 0x1f0
lpt0 at upc0 offset 0x278
com0 at upc0 offset 0x3f8: ns8250 or ns16450, no fifo
...
What we haven't got:
- FDC support (found, but not configured).
- Clearing lpt interrupts on arm26 systems (needs help from IOEB).
- A upc(4) manual page.
- More than minimal testing (my A3020s don't have root devices).
- A proper probe routine (arm26 can't use one anyway).
driver and make it MI):
Set the ByteSwap bit on big-endian hosts, so we can use 16-bit transfers to get
at packets whatever.
Treat Tx/Rx headers as arrays of four bytes rather than as 32-bit words.
Transmit and receive buffer sizes aren't an intrinsic property of the card,
so they belong in if_ea.c rather than if_eareg.h.
Correct some comments in if_ea.c
that the ROM page registers on the podules are likely to end up pointing at
the page with the ECID in it, so NetBSD can recognise the podules.
This is necessary for my i-cubed EtherLan cards, at least.
- Get the Ethernet address from the card's description string, rather than
relying on RISC OS to set it.
- Don't mention this is a SEEQ8005 -- that's all an "ea" can be.
- Use format_bytes to display the amount of buffer RAM.
* put #includes of opt headers and headers to get protos used by
net/netisr_dispatch.h in net/netisr.h (if !defined(_LOCORE)) (rather than
in netisr_dispatch.h itself, and potentially nowhere, respectively).
* require netisr.h to be included before netisr_dispatch.h.
* minor additional cleanup of both netisr.h and netisr_dispatch.h.
* clean up uses to remove now-unnecessary header file inclusions, and
local prototypes of the fns.
* convert netisr dispatch implementations which didn't use
netisr_dispatch.h (pc532) to use it.
- for sizeof(void *) == 8 arch, this is mandatory. MHLEN is too small
already (less than 80) and there are chances for unwanted packet loss due
to m_pullup restriction.
- for other cases, the change should avoid allocating clusters in most cases
(even when you have IPv4 IPsec tunnel, or IPv6 with moderate amount of
extension header)
portmasters: if your arch chokes with the change (high memory usage or
whatever), please backout the change for your arch.
