v_caddr_t with extreme prejudice. Here the bogons were originally
the same as for c_caddr_t (half-baked K&R support), but rev.1.95
changed one wrong cast and one harmless cast to 2 wrong casts,
and rev.1.96 only fixed the originally wrong cast.
c_caddr_t with extreme prejudice. Here the original casts to
caddr_t were to support K&R compilers (or missing prototypes),
but the relevant source files require an ANSI compiler.
Auto Detection Mode. This leaves MSP3400C owners still unsupported.
Thanks to Gerd Knorr <kraxel@cs.tu-berlin.de> for providing some early
assistance and sample code in the linux bttv driver.
Nicolas Souchu <nsouch@freebsd.org> ported the msp_read/write/reset
functions to smbus/iicbus.
METEOR_INPUT_DEV2 now selects a composite camera on the SVIDEO port.
For true SVIDEO, use METEOR_INPUT_DEV_SVIDEO.
If you get a monochrome image from the SVIDEO port, you have
seleted the wrong input type.

in addition to Compaq and Olicom. (I don't actually have a card that
reports the TI vendor/device ID, but it appears that some Racore adapters
work this way, and failing to account for it when we have the ID listed
in the supported devices list is a bug.)

we have to flip on all bits in the table for multicast mode.

The previous code just ignored the invalid map register, but this gave
surprising results because of the way pci_map_port() associated the map
register offset supplied with a map entry in the map array.
to look up cookies properly, at least for standard controllers.
Cookies are used so that we don't have to pass around lots of args.
All of the dmainit functions use the unit number so it is essential
that we pass them a cookie with the correct unit number.
This may break working configurations if there are bugs in the
dmainit functions like the ones I just fixed for VIA chipsets.
Broken in: rev 1.4 of ide_pci.c and rev.1.139 of wd.c.
Prefetch/postwrite was enabled for the wrong controller. (VIA
is bitwise big endian and we confused ourself by shifting left
instead of right.)

Instead of initializing UDMA mode, we turned it off and made sure that
it stays off by turning on the "UDMA enable by SET FEATURES" disable.
The damage was limited by bugs in cookie lookup, and suitable
initialization by some BIOSes. The cookie list has slaves before
masters, and the unit number is ignored when cookies are looked up,
so cookie lookup always finds cookies for slaves and the bug only
clobbers slaves, so the bug was harmless for common configurations
with no slaves or only non-UDMA slaves. UDMA initialization for
masters actually worked if the BIOS turns on the UDMA mode bit and
turns off the "UDMA enable by SET FEATURES" disable.
- In wb_rxeof(), if the received packet is less than MINCLSIZE bytes,
copy it to an mbuf chain so as to be more frugal in our use of mbuf
clusters.
- The Winbond chip, like the ASIX, wants the 'TX interrupt request'
bit set in the _first_ fragment of a transmitted frame, not the
last. (At least the Winbond manual states this unambiguously; too
bad I wasn't paying attention when I read it the first time.)
- Turn off the transmit threshold mechanism (initialize the threshold
to 0). This effectively puts the chip in 'store and forward' mode
which seems to cut down on transmit errors a little. It may also
reduce transmit performace a bit, but I'm willing to do that if it
means better reliability.
- Normally, the driver allocates an mbuf cluster for each receive
descriptor. This is because we have to be prepared to accomodate up to
1500 bytes (a cluster buffer can hold up to 2K). However, using up a
whole cluster buffer for a tiny packet is a bit of a waste. Also,
it seems to me that sometimes mbufs will linger in the kernel for
a while after being passed out of the driver, which means we might
drain the mbuf cluster pool. The cluster pool is smaller than the
mbuf pool in general, so we do the following: if the packet is less
that MINCLSIZE bytes, then we copy it into a small mbuf chain and
leave the mbuf cluster in place for another go-round. This saves
mbuf clusters in some cases while still allowing them to be used
for heavy traffic exchanges with lots of full-sized frames.
- The transmit descriptor has a bit in the control word which allows
the driver to request that a 'TX OK' interrupt be generated when
a frame has been completed. Sometimes, a frame can be fragmented
across several descriptors. The manual for the real DEC 21140A says
that if this happens, the 'TX interrupt request' bit is only valid
in the descriptor of the last fragment. With the ASIX chip, it seems
the 'TX interrupt request' bit is only valid in the descriptor of
the _first_ fragment. Actually, the manual contains conflicting
information, but I think it's supposed to be the first fragment.
To play it safe, set the bit in both the first and last fragment to
be sure that we get a TX OK interrupt. Without this fix, the driver
can sometimes be late in releasing mbufs from the transmit queue
after transmission.
if option CY_PCI_FASTINTR is configured and mapping the irq to a
fastintr is possible. Unfortunately, this has to be optional because
pci_map_int_right() doesn't handle the INTR_EXCL flag right --
INTR_EXCL is honoured even if the interrupt needs to be non-exclusive
for other devices to work.
using the new pci_map_int_right() variant of pci_map_int(). Fast
interrupts work for PCI devices if and only if they are exclusive.
(The PCI interrupt mux doesn't support fast interrupts and can't
support a mixture of fast and slow interrupts even in principle.)
Don't assume that intrmask_t == unsigned in pci_map_int().

on the ASIX AX88140A chip. Update /sys/conf/files, RELNOTES.TXT,
/sys/i388/i386/userconfig.c, sysinstall/devices.c, GENERIC and LINT
accordingly.
For now, the only board that I know of that uses this chip is the
Alfa Inc. GFC2204. (Its predecessor, the GFC2202, was a DEC tulip card.)
Thanks again to Ulf for obtaining the board for me. If anyone runs
across another, please feel free to update the man page and/or the
release notes. (The same applies for the other drivers.)
FreeBSD should now have support for all of the DEC tulip workalike
chipsets currently on the market (Macronix, Lite-On, Winbond, ASIX).
And unless I'm mistaken, it should also have support for all PCI fast
ethernet chipsets in general (except maybe the SMC FEAST chip, which
nobody seems to ever use, including SMC). Now if only we could convince
3Com, Intel or whoever to cough up some documentation for gigabit
ethernet hardware.
Also updated RELNOTEX.TXT to mention that the SVEC PN102TX is supported
by the Macronix driver (assuming you actually have an SVEC PN102TX with
a Macronix chip on it; I tried to order a PN102TX once and got a box
labeled 'Hawking Technology PN102TX' that had a VIA Rhine board inside
it).
and mx_setcfg() so that we can read the internal MII registers on the
MX98713 chip correctly. With these changes, media autoselection now
works correctly on the original 98713. All Macronix chips should now
be properly supported (unless there's a surprise waiting in the 98725).
Thanks to Ulf Zimmermann for providing a 98713 board.
isolated to revision 33 PNIC chips is also present in revision 32 chips.
Cards with rev. 32 chips include the LinkSys LNE100TX and the Matrox
FastNIC 10/100. This accounts for all the cards that I have to test
with.
(I was never able to personally trip the bug on this chip rev, but today
one of the guys in the lab did it with the software they're working on
for their cellular IP project, which uses BPF and promiscuous mode
extensively.)
This commit enables the promiscuous mode software workaround code for
both revison 32 and revision 33 chips. It's possible all of the PNIC
chips suffer from this bug, but these are the only two revs where I
know for a fact it exists.
