into a strange failure mode if we do it with disabled interrupt. When
(re-)enabling interrupts reset transmitter and receiver and clear any
pending state.
not pre-load the chip's Tx buffer, but instead waits for the Tx Ready
interrupt to transmit the first chunk of data.
* On the IOP310, set COM_HW_NO_TXPRELOAD, rather than COM_HW_TXFIFO_DISABLE.
This solves the "UART hangs" problem on the Npwr in a nicer way (i.e. we
get to use the FIFO, whee). The COM_HW_NO_TXPRELOAD happens to match the
Linux 16550 driver's Tx algorithm, and the "UART hang" was never observed
on the Npwr running Linux.
Eventually, we might want to eliminate the COM_HW_NO_TXPRELOAD, and simply
always use its algorithm. But it should be tested on more 16x50 variants
before we do that.
Kudos to Valeriy Ushakov <uwe@netbsd.org> for pointing out this solution
(which also happens to fix the stray UART interrupt issue on the Krups
Javastation), and to Allen Briggs <briggs@netbsd.org> for experimenting
with various methods of fixing this.
Note: The code is written a little more cruftily than it should be. It's also
only tested on the OSB4. I'm not sure it even makes sense to have support for
`native' mode, but I put it in just in case.
are used- didn't make a difference, but hey...
Put in commented out GFF_ID code- for use in future attempts to search
the fabric- this probably has to go thru the management server path.
Don't whine about handles we can't find if these are aborted commands
(we know we can't find the handles because we destroy handles after
a successful mailbox abort- we don't wait for the F/W to decide whether
it wants to return a status IOCB after this happens).
the data transfer. This is mandatory for data out commands (although none are
used for now), and not forbiddend for data in commands. Also record if we
did transfers any data.
May solve kern/16159 by making the probe more robust in face of fake identify.
for the same purpose (ignoring invalid interrupts).
For cards that are not able to stop all interrupts (or we don't know a way
to do that in software, at least) run the clearirq callback even when
ignoring an interrupt because we are not enabled. Otherwise the card would
stop interrupting.
Reserve a driver specific callout handle and an int value in the generic
isic_softc to allow card drivers to implement fancy blinkenlights.
It improves playing/recording quality greatly
and it was almost done by Yosuke Sugahara <penta@fuchu.or.jp>.
Thanks a lot!
Add support of slinear8, slinear16_le, slinear16_be.
pcmcia cards. Now that pcmcia attachements properly handle the activate
callback, this is no longer needed (and is suspect to cause completely
unrelated problems.)
count them when reading the NIC counters - it doubles the count. Read the
NIC counters to prevent counter overflow interrupts, but don't add them to
the interface counters. Don't bother reading the upper counts because they
are just latched when reading the totals.
Fixes final part of PR#11549.
on the following PRO/100 chips:
* i82558 step A4
* i82558 step B0
* i82559 step A0
* i82559S step A
* i82550
* i82550 step C
The interrupt delay is configurable on all microcodable chips. The
maximum "bundle" size (packet count) is configurable on all but the
i82558.
The microcode is enabled by setting IFF_LINK0 on the interface.

the interface was wired to full-duplex mode. Duh.
Also, add OPMODE_TTM to OPMODE_MEDIA_BITS, to insure that it is changed when
we switch between 10 and 100.
to be trying to wriggle out of supporting this well. Instead, use
GID_FT to get a list of Port IDs and then use GPN_ID/GNN_ID to find the
port and node wwn. This should make working on fabrics a bit cleaner and
more stable.
This also caused some cleanup of SNS subcommand canonicalization so that
we can actually check for FS_ACC and FS_RJT, and if we get an FS_RJT,
print out the reason and explanation codes.
We'll keep the old GA_NXT method around if people want to uncomment a
controlling definition in ispvar.h.
This also had us clean up ISPASYNC_FABRICDEV to use a local lportdb argument
and to have the caller explicitly say that a device is at the end of the
fabric list.
The ICH on-board Ethernet and some i82559 chips have a bug which
will cause a PCI protocol violation if the chip receives a CU_RESUME
command as it is entering the IDLE state by deasserting #CLKRUN.
(This is the so-called "resume bug" that we previously had an incomplete
work-around for on ICH chipsets.)
The work-around is to disable Dynamic Standby Mode, such that the
chip will never deasert #CLKRUN. Dynamic Standby Mode is disabled
by clearing a bit in the EEPROM and updating the EEPROM (and EEPROM
checksum).
Unfortunately, the chip will only consult the EEPROM setting after
a PCI bus reset, so a system reboot is required once the EEPROM
has been updated (the EEPROM update only needs to happen once,
and the driver usses a warning instructing the user to reboot the
system once the work-around has been applied).
Issue pointed out by David Brownlee, and code more-or-less lifted
from FreeBSD.
adding "alpha_" / "ALPHA_" prefix to items as appropriate. Rename
CHECKSUM_BOOT_BLOCK() -> ALPHA_BOOT_BLOCK_CKSUM(). Add cgd's copyright

- Clean up a couple of comments.
Set this to dv_xname for scsibus and atapibus.
Set the name of the kernel thread to chan_name instead of controller's
name:channel number (so that we can use this name for controller-specific
threads).
for bus_dmamap_sync calls. They'd been blindly ported from Solaris which
had *one* dma map for the entire control space, so offset was incremented
for the Request, Response and FC Scratch spaces. Tsk. There are three maps
in NetBSD. I should probably make them one anyway.
all function pointers passed in from the adapter driver.
This partly fixes PR 13480, i.e. the FREECOM CD driver works now in pcmcia
adapters.
The remaining issue (timing problems with slow cards and cardbus bridges)
is probably the cause of several other PRs too.

This makes my FreeCOM CD drive work at first attach (PR 13480).
Something is wrong with the detach code; it won't work on second attach
and will panic on second detach - but that has to wait until the kids
took care of some easter eggs.
1. Fix setting of nominal fan speeds with ENVSYS_STREINFO.
2. Treat Winbond 83781D specially because it has a programmable divisor for
FAN3 unlike generic devices.

possible pending interrupt. This should avoid the interrupt loop described
in PR kern/15841.
It is safe to read status here, because if we're not waiting for an interrupt
we have no command pending, so the device should be idle.

Implement detach/(de)activate for PCI cards.
Clean up internal state (free call-descriptors) if a controller is

B-channel and D-channel drivers separately) split the Fritz!PCI card
driver out of the isic driver.
The new device is called "ifpci" and uses the same D-channel driver as the

Make the ISA probe actually (silently) fail if no card is found.

We may revisit this once a general interrupt queuing mechanism is
available and we can avoid calling the pcmcia cards interrupt handler at
an exsessive IPL.
and move them in their proper places.
Move the BRI registry from layer 2 (duh!) to layer 4, so active cards
(which don't have layer 3 or layer 2 in their driver). Remove all remaining
hard coded controller and driver types. Remove any arbitrary hard coded
limits, at least those that show up in the internal API.
This fixes PR 15950.

This fixes a problem that the card would be treated as ESP100 in
ncr53c9x_reset(), but not on couple other places (pointed out by
Andy Doran in private e-mail).

With this change, voices are stopped on suspend, and continue from where they
left off on resume.
ACPI defines two different battery device interfaces: "Control Method"
batteries, in which AML methods are defined in order to get battery
status and set battery alarm thresholds, and a "Smart Battery" device,
which is an SMbus device accessed through the ACPI Embedded Controller
device; this driver knows how to attach to the former sort of device.
As a total kludge, since we haven't wired things up to sysmon/envsys
yet, we report battery status through a once-per-minute kernel printf,
so don't use this driver yet if you want your disk to spin down.
Motivated by and tested on Sony PCG-R505TL laptop, which has
nonfunctional APM.

inserted into comments. I really think that more testing was required,
but Christos was eager.
+ Add in tape block/file position reporting support.
+ Change the prevent/allow ejection code so that if the device
is close the tape can be ejected. This allows robots to eject
the tape even if the tape isn't at BOT.
+ Don't do a null filemark write if we're reading block position. This
was such an abysmal performance killer that it had to go. Assume
that the tape will DTRT and tell you what the tape position really is
including any buffered data. You are depending on the tape to do
the right thing to report position at all, so the risk factors don't
increase appreciably here. BTW- we only do this for logical block
position. For 'hardware' block position, we still flush.
+ Some substantial tweaking in st_interpret_sense. This essentially duplicates
the FreeBSD driver's exception handling code. This is to try and correctly
handle EOM cases. I'm not sure that this is now correct with respect to
the ENABLE EARLY WARNING code- I hadn't gotten around to validating that.
Add in full 32 bit residuals- this can then be available to an update
MTIOCGET in the future.
+ Make sure we handle SKEY_VOLUME_OVERFLOW correctly.
