particular, make sure that all the SIASTAT_ANS bits are in the right state
so we don't do something inane.
Still doesn't actually bring the link up properly, but at least it negotiates
most of the time, and does it a little faster.
1) Do not call tlp_sia_update_link() in Nway mode, and do not look at SIASTAT
in any other place that nway_status(), where we first check that it's valid.
In other places, look at IFM_ACTIVE after having call nway_status().
2) Eliminate stupid MII_MEDIACHG calls, and arrange for nway_service() to
update status on every call.
3) Nuke the synchronous case of nway_auto() from orbit.
4) Do not call nway_statchg() when using manual configuration; tlp_sia_set()
does everything we need.
1) Set OPMODE_TTM in the default tsti_opmode, so that nway_status doesn't
blow up and report the wrong media type when statically configured. (This
code is a hack.)
2) Do not set IFM_ACTIVE (i.e. ignore SIASTAT_LS*) when in auto-negotiation
mode and negotiation has not completed (per 21143 manual).
3) Do not clear auto-negotiation mode; otherwise the chip will not
renegotiate on a link failure.
With these changes, 10/100 selection is more stable, and auto-negotiation
comes up with the right status and detects link, but the link does not work
unless it's hardwired. More work is needed.
transmit and receive descriptor rings is limited to 256 descriptors.
So, set the if_snd queue length to 256 to let the upper layers queue
lots of packets, and let the driver handle up to 32 of them at a time.
(We should probably make this change to most Ethernet drivers, since
it actually saves some resources.)
* Increase the number of Tx DMA segments from 8 to 16.
* Clean up the way we count "how many times did I get a packet with N
DMA segments".
* Add a missing htole32() in wm_tx_cksum().
* Don't set both RS and RPS in the last Tx descriptor of a packet; just
use RS.
* Add some more information to the watchdog message.
so that they're more useful for arbitrary types of external storage:
* Add an "mbuf *" argument to (*ext_free)(). If non-NULL, (*ext_free)()
is expected to free the mbuf itself. This allows (*ext_free)() to use
the mbuf for bookkeeping (e.g. deferring the work to a helper thread).
If the "mbuf *" argument is NULL, we are assumed to be in a context
which is safe for performing the destructor operation *now*.
* Adjust MEXTREMOVE() and MFREE() routines for above change.
* Update "ade" and "ti" drivers for new semantics.
It is unclear if this realy is needed and if, on which type of cards. I
haven't run accross a card that needs it yet. This may have been just
a copy & pasto from the ISAC interrupt handler carried over to IPAC.
Remove the clear-the-irq-after-enabling it dance (which had bad side
effects on some cards). Instead disble the ISAC receiver when we have
interrupts disabled. Adjust the interrupt handler to properly deal with
subtle differences of the ISAC implementation in IPAC chips.
if error occurs after status is collected) race condition
when using the status byte to detect completed commands (a command descriptor
could be recycled before the device disconnected), and make the
interrupt routine handling completed commands more efficient (no need to
scan target * lun * tag array any more).
there may be tagged commands still running when we queue a request sense
command.
Solve this by using 2 DSA entry per LUN
- Now that we have the command DSA before select, we can load T/L/Q in
SCRATCHC. This makes the selection timeout handler simpler.
- Avoid a race condition when setting the free flag in the cmd ring (see
comment in the script)
- don't forget to update the ID in the head of LUN table after a sync/wide
negotiation. This fixes the command timeout at the first data command
after negotiation (the bus reset handler did update the ID properly,
so subsequent commands were OK).
- for DMA interrupts, clear fifo if it's not empty. Leaving the fifo dirty
would prevent subsequent interrupts from coming in.
- Various improvements in debug messages
- misc cleanups.
scheduler slot. This costs a few more instructions but divide the size of the
scheduler ring by 2, saving 1k of onboard RAM (a bus with 15 devices would
overflow the on-board RAM by 128 bytes).
- Add support for DT transfers (aka Ultra/160) in esiop
Note that DT transfers are not enabled for 53c1010-33 rev 0 yet; if I trust
FreeBSD it has a bug which prevent them to do DT properly.
From the same source there may be issues with some revs of 53c1010-66.
So check for version 3, not 4 when looking for DT support.
This should be safe as these bits are reserved for older devices, they
should be set to 0 when not supported.
taken from OpenBSD. Test hardware kindly provided by Intel. This still needs
management bits, and doesn't support older controllers, but that shouldn't
be hard to fix.
after the selection timeout is posted but the number executed isn't
reliable. So wait for MSG_OUT rigth after the select so that the state of
the script when the interruption is handled is known.
For this add another indirecton: the DSA in the LUN table points to
a table of DSA indexed by the tag number when tagged command is in use.
For non tagged command, the LUN DSA still points to the tables describing the
xfer directly.
yet.
If is restricted to SIOP which implement the load/store instruction, and
has 10 scratch registers (basically, 825 and newer, possibly 770).
It implements a different interface between host and script, using a real
ring for command starts, and improved support for reconnect which will allow
256 tag per device. It uses interrupt on the fly to signal complete command,
which allows several commands to be serviced per interrupt and doesn't require
the script to stop to signal command completion.
3 bits are lun address modifiers.
Remove code that (incorrectly) thought it was asking the f/w to only
PLOGI if not already PLOGI'd. The current f/w documentation tells us
that we have this backwards.
"true" at the appropriate times for non-PCMCIA interfaces. This
means that the ENETRESET path in cs_ioctl() now runs, thus fixing
multicast (and IPv6) on my Shark. Yay.
* Simplify cs_hash_index(): Rather than taking the bottom 6 bits of
a big-endian CRC32 and reversing them, just take the top 6 bits of
a little-endian CRC32.
So to disable them all better use 0xff instead of 0x00 as mask. Noted
by Matthias Drochner.
Move some initialization unrelated to interrupts back to its place at
attach time.
WI_RID_SCAN_APS in previous commit works for Intel Pro/Wirelss 2011
with firmware 2.51.1.
It seems that the firmware automatically updated after the card runs on
Windows 2000 with 2011_2011B_CD_3.0 in Intel web site.
* Pull in dev/mii/files.mii from conf/files, rather than playing
the magic "files include order" dance in N machine-dependent
configuration definitions.
The card is Type 1 CF card and it doesn't have firmware in.
So we need to download the firmware image into the card before
touching it.
XXX downloading code should be written in generic (bus independent),
but I don't have enough information for now.

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.

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 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.

Set the name of the kernel thread to chan_name instead of controller's
