function is called when carrier is lost in lieu of a console message.
This is used by the sparc port to switch media types on Sun4m machines
if the appropriate link flags are set by ifconfig (see following commit
message). Should not affect ports that do not use sc_nocarrier().
old config anymore, all devices should use new config by now.
Add structures to handle DMA devices using new config.
Fixed bug that caused unwanted ubareset's on 11/780.
to ignore inbound data sizes less than the threshold. otherwise,
when connected to a video aal0 input the driver gives us a massive
stream of 56 byte mbufs each with one aal0 cell in it and the
system just can't keep up with it, especially if the socket buffer
size is large [it hangs until you turn off the video source].
fixes: when turning off a vc, try and check the freshest copy of the mode
when seeing if we need to enter the "drain" state. also, don't
panic if we get unexpected rx interrupt on a VCI (instead make sure
the VC is off, print a warning, and move on!).
- change rxso into a void handle ... no need to know details at this low
level.
fix:
- forgot to init "vci" during ENOTHER_DRAIN case of RX DMA interrupt
[could cause a vm_fault on native mode connection close depending
on needing to drain out the VC and also the random value of vci]
- more stat counters (rxmbufout -- mbufs, ttrash -- trashed RBD)
- add swsl_size to keep track of size of software slist
- revise when we call en_service
- fix handling of circular lists (was getting full vs empty confused in
extreem cases...)
- native mode atm: remove sbappend code: can't do it here since
socket buffer is protected only by splsoftnet and that doesn't
mask enintr off. forces us to switch to a two level interrupt
scheme. revise call to atm_input to reflect that.
[1] rxslot "cur" pointer wasn't updated if we copied all data and
didn't have any fill. this could cause a service id mismatch
panic under load.
[2] recv of aal0 forgot to include the cell header in the data length
calc [add cell header length to midwayreg.h]
[3] fix control info "chop" for raw mode and aal0
[4] handle rxsb better for native atm connections
(XXX: still working on this ... not complete and needs revision)
Enable reselections as soon as possible after a disconnect - prevents
losing a reselecting device.
Check for and ignore a spurious interrupt during a DMA input (from the
Mach driver).
Turbochannel as well as the IOASIC. It should now work on the 5000/200.
Removed the "aborts" which could leave the disk trashed when the abort
rebooted the system. Fix the data corruption problem by clearing the
FIFO before starting a data transfer.
all attempts to mode select, even if the attempted mode is supported.
Add the ST_Q_UNIMODAL quirk for the HP Colorado T4000s which exhibits
this behavior. (Someone please lob a tactical nuke in that direction.)
From David Rosenthal <dshr@vitria.com> on netbsd-bugs.
* Change MachEmptyWriteBuffer() to wbflush(). Should use TC mi names tc_mb(),
tc_wmb, tc_syncbus() but I'm not sure which each wbflush() should be.
* Add prototyped forward decl for asc_Dumplog() and add an explicit void
return type.
* Remove unused variables.
alpha. At some point in the future, those headers should be provided
on the pmax, but until then, things are #ifdef'd so that the old
headers and definitions are still used. Pass a bus_chipset_tag_t
to the TC bus attach code and to devices, on the alpha.
to the ring (or silo). This eliminates ring overrun with crtscts.
Also handle deferred register changes earlier, and misc. cleanup.
Give credit to: Bill Studenmund and Ian Dall (Thanks!)
While I'm here, convert driver to use <machine/bus.h> and the new PCI
I/O space interface (the new PCI interrupt interface was already in-use).
Also, correct a "corrected" printf.
bits that tell the driver not to expect parity from those targets.
XXX: For now, it is up to MD code to set this mask. Eventually,
XXX: we should identify targets first (without demanding parity)
XXX: and then use a new "SCSI quirk" to set the right bit.
naming conflicts between bus attachments on ports that can have
multiple instances of the LANCE.
Changed struct ifnet to have a pointer to the softc of the underlying
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit. Updated interface to (*if_watchdog)() and (*if_reset)()
to take a struct ifnet *, rather than a unit number.

(and only tested on) Intel Etherexpress PRO. Should work on any i82595 ISA
board which uses an EEPROM for config information; NETBLKID not yet supported.
TODO: change to BUS interface, add multicast support.
Use the i/o handle for the `delay port' exported from the parent
ISA bus, rather than the totally bogus combination of [ioh, 0x84].
Also, fix a bug apparently introduced when the -Wall changes were checked
in which, under most circumstances, would cause a 16-bit WD8013EP to
be mis-identified as an 8-bit WD8003EP.
For the ISA probe, implement a way to keep track of which ISA busses
have been through an ep_isa probe; the static variable that was used
before didn't scale.
In elink_reset(), since some machines may have more than one ISA bus,
implement a way of keeping track of which ISA bus has received an
elink_reset(); The static variable which was used previously didn't
scale.
bus-independent core driver. Tested on all three bus types, including
an isa 3c509 masquerading as an eisa device (use ep* at eisa? slot ? in
your kernel config file to catch this one).
XXX Driver still needs to be converted to <machine/bus.h>
remove their 'integrate' (usually defined to be 'static') keywords.
when lance drivers are split up by attachment, more than one file will
reference the copy/zero functions (i.e. not just the file that pulls in
am7990.c... and eventually inclusion of am7990.c should go away entirely).
chip-independent clock code. 'clock' has been renamed 'mcclock' 'clock'
has been renamed 'mcclock' (since it's a driver for that particular
clock, and since eventually there may be another clock chip driver),
and now attaches via seperate match/attach functions to both TC and ISA.
This removes a whole lot of #ifdefs...
'cflag' for the console. Normally set to TTYDEF_CFLAG, may be
overridden by machine-dependent console attachment code, as necessary.
(Alpha uses it to set cs8 -parenb.) Files including comvar.h now
need to include <sys/termios.h>, because comconscflag is of type
tcflag_t.
tech-kern (?)), to get the IPL_* and IST_* types. pass the machine-dependent
cookie given at attach time on to sub-devices, so they can use it to access
the interrupt functions properly.
the isa_chipset_tag_t type, and to define or prototype:
isa_attach_hook()
isa_intr_establish()
isa_intr_disestablish()
i.e. the machine-dependent functions to be used my MI ISA code.
Remove prototypes for the latter two functions from this file.
the bus is configured, interrupts are handled, etc. machine-dependent
header (machine/eisa/eisa_machdep.h) defines eisa_chipset_tag_t and
eisa_intr_handle_t types, and the following functions:
eisa_attach_hook()
eisa_maxslots()
eisa_intr_map()
eisa_intr_string()
eisa_intr_establish()
eisa_intr_disestablish()
Don't define the interrupt establish/disestablish functions directly
in terms of the ISA functions any more (on some wacked out systems,
there can be a difference).
* Add an ACB_RESET flag, so that a BUS DEVICE RESET can be queued within the
driver.
* If ACB_ABORT or ACB_RESET is set during reselection, schedule a message and
assert ATN.
* Optimize aic_datain_pio(), aic_dataout_pio() and aicintr() somewhat.
* Schedule a timeout only when we select the target, so that commands can't
time out prematurely.
