in the non-MULTIPROCESSOR case (LOCKDEBUG requires it). Scheduler
lock is held upon entry to mi_switch() and cpu_switch(), and
cpu_switch() releases the lock before returning.
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.
