descriptor count gets miscounted on txprobes. The second (and more
important) is that transmit stalls should now be fixed. The problem
was not due to lack of ring resources but dmamaps. When Jason changed
the driver to use pre-allocated maps (instead of the dynamic ones I
used), and when there were no more maps, the driver just gave up instead
of calling tx_intr to free any transmitted but unreclaimed dma maps.
Since there was nothing being transmitted, no transmit interrupts
would fire to restore things (and OACTIVE prevented other transmits
from happenning). So it stayed starved until another interrupt cause
(like a received packet) "woke" it up.
-use of uninitialized variable in attach (mostly harmless)
-removal of dead code in attach()
-fix of interpretation of SIA blocks on >=21142 (serious, caused strange
things with 10Mbit)
egcs won't attempt to optimize inline copies of them into a single
load/store (the RFA is not 4-byte aligned in the DMA area).
Just use memcpy() to copy those fields, now, not our own home-grown.
cursor code. These are unneeded on the Bt485, since the RAMDAC handles
the hardware cursor. They are needed for the Bt463, however, since the
RAMDAC only provides cursor color.
* Improve the midisyn layer a little.
* Add a driver for the Yamaha OPL[23] FM synths.
The opl driver is not finished yet; it sounds pretty awful.
For some strange reason I cannot get any FM sound from my SB64 cards,
but a regular SB16 works fine.
if i drive is responding):
-if the reset succeeds, check some registers to make sure there is really
a drive (and not a chipset which echoes back the last written value)
-explicitely select the master before trying to read the master's status
the 3Com 3c905-TX and 3c905-T4. Fix handling of the MII on the
3c595-MII and 3c597-MII (can't talk to the PHYs on these cards; just
use "manual" for the external MII port).
Fixes kern/4782 (Chris Demetriou).
if_tlvar.h, since the ThunderLAN PHY driver needs to know some things
about it's parent (and since it can only attach to a ThunderLAN chip,
this is the easiest way).
associated with any observed lossage...it was just noticed while reading
ncr_start().
g/c some now-unreachable code produced by the earlier race condition fix.
* Use the new trigger_{in,out}put interface.
* Allow the play and record channels to have different encodings (but the
same sample rate).
* Play u-law and a-law as 16-bit data. (This may not work yet...)

Makes the whole concept useless. This is for default printouts. If you
can build a debug kernel, you know what version you have. This was under
the concept of 'RAS' so that hapless users could tell you microversion
things. But I guess this isn't the right way according to our local
Jesuits. Oh, well. I'll think up something different and hopefully
less objectionable. And yes, NetBSD isn't linux. The developers seem
to be equally bad tempered, but linux is more successful.
Part B:
Field interrupts in OS layer so that (in this OS) bus_dmamap_sync(POSTREAD)
can (formally) ensure that the result queue is stable wrt to buffering
and that for sending a command a bus_dmamap_sync(PREWRITE) is done to
ensure that the device gets a good view of what the mailbox contents
should be.
which contain 'standard' com- and lpt-type ports. Some of these present
as PCI simple-communications/serial or simple-communications/parallel
devices, but many do not. (Additionally, there is no document that I can
find that describes the "specific well-konwn register-level" description
of how the 'standard' devices' config space headers shold work.) Eventually,
some of the devices driven by this code should become simple pci attachments
for the 'lpt' and 'com' drivers, but that requires solid documentation.
the BAR-printing function to print a name for the register, factor out
a common register-bits function which can handle the fact that type 2
headers have a different size than is usual, and actually do something
useful with the rest of the bits in the type 2 header.
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
used in the SMC EtherPower II.
Media control isn't yet supported, due to some MII infrastructure
problems which I hope to address soon. This isn't a huge deal, since
the PHY defaults to auto-negotiate mode.
Also, the device just programs the multicast hash table to accept all
multicast, to avoid a hardware bug that causes the multicast address
filter to lose in 10Mb/s mode. This bug will be fixed in a more sane
way once the media control issues are dealt with.
of last resort when trying to communicate information about
bogus behaviour of PCI devices to the MI autoconfiguration code.
In general, bogus behaviour should be handled by drivers, but there
are some types of bogons which can't be addressed that way. The
only quirk currently defined is one which indicates that the device
is multi-function even though the device's header says otherwise.
(Mmm, Intel 82371FB PCI-to-ISA Bridge (PIIX); you'd think that at least
Intel would have gotten it right...)
of functions on a given device. Also, clean up the #if 0'd
major-debugging-spew code so that it's all one piece, so that
it's a bit prettier, and so that it prints out quirk information.

printing into a function, add a bit more pretty-printing of existing stuff.
Implement pretty-printers for type 1 and type 2 headers. (Right now,
these are just quick stabs based on some on-line bridge docs that I have
handy on my laptop. Mmmm, meetings. I'll check the bits when I get
back within reach of my official docs.)
lots of data, e.g. ~18k on a PCI system with few add-in devices; use
with MSGBUFSIZE=...). Useful to have here so that people who want as
much data about the PCI configuration in a machine can get it without
having to craft their own code. Also, clean up a few of the other
#if 0'd printfs.
* print all configuration space registers. Then, where possible,
interpret them. (That is, PRESENT ALL THE DATA, then interpret it --
don't hide data behind interpretation. Also, when interpreting
fields, try to print out the specific value that's being interpreted.)
* handle different header types.
* allow caller to specify a function which can interpret the
device-dependent header and is responsible for pretty-printing it.
It spews (use 'options MSGBUFSIZE=...' 8-), but when you want the data,
you really want _all_ of it.
Still needs some cleanup and additional code (e.g. interepretation
of PCI-PCI (type 1) and PCI-Cardbus (type 2(?)) bridge headers).
pci_mapreg_info() call. pci_mapreg_map() implies this check,
but code which calls pci_mapreg_info() has to check it explicitly.
Otherwise, if memory space is disabled, the driver does the wrong
thing, and tries to use memory space anyway, potentially resulting
incorrect driver operation and no useful error message.
The graphics device driver passes a "default attribute" for normal text
output to the wscons framework. If the emulation module needs more
attributes (for different "renditions") it can allocate them via a
callback.
For now, only the "sun" emulation makes use of it.
needs some testing, but it seems to produce sound. The driver was written
by me, but since I don't have the hardware the debugging and testing was
done by Andreas Gustafsson <gson@araneus.fi>, Chuck Cranor
<chuck@maria.wustl.edu>, and Phil Nelson <phil@cs.wwu.edu>. Thanks.
ID) when determining if the Vendor ID is invalid. The spec says that
Vendor ID of 0xffff is invalid, so, it doesn't _matter_ what the product
ID is in that case. Treat Vendor ID 0 as invalid because we always have.
and see if anything responds. if nothing (that's attributable to the
PCI IDE controller) responds, then that channel either has no devices on
it or has been disabled (via a non-standard mechanism) by the BIOS. If nothing
responds, don't map the compat.-mode interrupt or attach the wdc to that
channel, because the BIOS is likely to assign that IRQ to a different PCI
device. If that happens, the kernel will panic because that device will
try to map the IRQ level-triggered, but the compat interrupt will have been
mapped edge-triggered. (One possible way around this is to map the compat
interrupt edge-triggered, but it's not clear reading the spec that this
is correct or desirable.)
insert a check to see whether a channel appears to be enabled. Shouldn't
be necessary, according to the spec, but some PC chipsets allow individual
compatibility channels to be disabled. "I hate PCs."

declaration mess is resolved, and until then need to go into MD
files files in places where they play nice with the wdc declaration.
entry (because the same product id is used for the 640B, as well). Note
that a few of the entries (PCI0642, PCI0650A) no longer have data to
be found on the CMD web site, and note that PCI0650A should probably have
its "A" trimmed as well.
in pci/if_tl.c, call config_found() with a print function, instead of
printing ourself a message in if_tl.c if no miibus was found. The print
function is in mii/mii.c (mii_adapter_print()) so that it can be used by any
adapter (idea from the scsi system).
it simple, and allocate one for each transmit and receive descriptor.
In addition to being simpler and faster, this fixes a serious memory leak
in the transmit path.
tested on any other platform other than i386. Use of bus_dma(9) can be
turned by defining TULIP_BUS_DMA_NOTX and TULIP_BUS_DMA_NORX. These allow
one to determine if the problem is in the transmit or receive path.
A problem reported by mycroft is also fixed.
- Fall back on i/o space if mem space isn't available.
- Card reports mem space as prefetchable, but mapping the card into dense
space fails in nasty ways on the Alpha. Force mapping into sparse
space by clearing the BUS_SPACE_MAP_CACHEABLE bit (XXX!).
nullbuf (used to pad packets < ETHER_MIN_SIZE) is used for all tl
interfaces. Allocates only once, and never deallocate it (as we can't say
if another instance of the driver is interface is using it).
i/o-mapped space to always be used), we discover that at least one
ThunderLAN interface can't read the EEPROM properly if memory-mapped
access is used. Kludge around this for now by "prefering" i/o space.
- Do PCI space configuration like the other drivers. In particular,
don't _disable_ the space we're not using because some lame firmware
implementations might not reenable it on warm boot. Also, prefer
memory space always.
- Make match and info-gathering in attach table-driven.
- Rearrange things a bit to be a bit more visually pleasing during boot.
Also, fixup some #include problems.
- Work around a bug in the 82557 that causes the receiver to lock up
in certain conditions by kicking the multicast address filter if we
haven't heard anything come down the wire for some period of time.
- Fix a bug that could cause TxCB descriptor chains to cross page boundaries
on the Alpha.
- Remove some unneeded register masking.
- Fix a bug where too much data was copied from the config template, causing
memory corruption.
- Fix handing of if_timer (it was be cleared too early in some cases).
- Attempt to reduce the chances of receiver overrun by doubling the
number of receive DMA segments, and processing receive interrupts
before transmit interrupts.
- Remove a gratuitous assignment.
- Fix a bug where incoming packets were counted twice.
