8010b90dc6 First part of the fix for ohci_hash_find_td panic.
Some controllers submit bogus pointers to the Done queue.
ohci_hash_find_td fails to find these in its hash and panics. Instead of
panicing we now assume the whole done queue is lost and let the timeout
code to clean up the mess after us.

935e6be657 Fix a bug in the uhci driver that breaks large bulk IN transfers. The
uhci_check_intr() routine needs to be more careful about deciding when
the end of a transfer has been detected.

This allows me to remove the nasty workaround code from if_aue and if_cue.
Receive performance is now much better for these adapters (500KB/sec
vs. 350KB/sec).

Also removed unused KUE_CUTOFF define from if_kuereg.h.

a6d9a40e81 More USB ethernet tweaks:
- Sync ohci, uhci and usbdi modules with NetBSD in order to obtain the
  following improvements:
        o New USBD_NO_TSLEEP flag can be used in place of UQ_NO_TSLEEP
          quirk. This allows drivers to specify busy waiting only for
          certain transfers (namely control transfers for reading/writing
          registers and stuff).
        o New USBD_FORCE_SHORT_XFER flag can be used to deal with
          devices like the ADMtek Pegasus that sense the end of bulk OUT
          transfers in a special way (if a transfer is exactly a multiple
          of 64 bytes in size, you need to send an extra empty packet
          to terminate the transfer).
        o usbd_open_pipe_intr() now accepts an interval argument which
          can be used to change the rate at which the interrupt callback
          routine is invoked. Specifying USBD_DEFAULT_INTERVAL uses the
          value specified in the device's config data, but drivers can
          override it if needed.
- Change if_aue to use USBD_FORCE_SHORT_XFER for packet transmissions.
- Change if_aue, if_kue and if_cue to use USBD_NO_TSLEEP for all
  control transfers. We no longer force the non-tsleep hack for
  bulk transfers since these are done asynchronously anyway.
- Removed quirk entry fiddling from if_aue and if_kue since we don't
  need it anymore now that we have the USBD_NO_TSLEEP flag.
- Tweak ulpt, uhid, ums and ukbd drivers to use the new arg to
  usbd_open_pipe_intr().
- Add a flag to the softc struct in the ethernet drivers to indicate
  when a device has been detached, and use this flag to perform
  tests to prevent the drivers from trying to do control transfers
  if this is the case. This is necessary because calling if_detach()
  with INET6 enabled will eventually result in a call to the driver's
  ioctl() routine to delete the multicast groups on the interface,
  which will result in attempts to perform control transfers. (It's
  possible this also happens even without INET6 support enabled.) This
  is pointless since we know that if the detach method has been called,
  the hardware has been unplugged.
- Changed watchdog timeout routines to just call the driver init routines
  to initialize the device states without trying to close and re-open the
  pipes. This is partly because we don't want to frob things at interrupt
  context, but also because this doesn't seem to work right and I don't
  want to panic the system just because a USB device may have stopped
  responding.
- Fix aue_rxeof() to be a little smarter about detecting when a double
  transfer is needed. Unfortunately, the design of the chip makes it hard
  to get this exactly right. Hopefully, this will go away once either
  Nick or Lennart finds the bug in the uhci driver that makes this ugly
  hack necessary.
- Also sync usbdevs with NetBSD.

76fd432173 Fix a couple of bugs:
- The busy wait hack in usbdi.c was doing its timeout in microseconds
  instead of milliseconds.
- if_aue.c:aue_intr() is creating a bitmask by and'ing two bits when it
  should be or'ing them.

7b7b87d7ef Change the mechanism by which we detect that the firmware is already
running. It turns out that trying to read the MAC address when there's
no firmware creates a zero length transfer. This apparently doesn't
hurt anything on a UHCI controller, but OHCI controllers generate an
IOERROR, and the device doesn't initialize.

Instead, check the bcdDevice revision code. We know this will be
different when the firmware is running, so if we detect the firmware's
code instead of the bare hardware's code, we skip the firmware load.

4640135aaf Minor enhancement: set the 'dual link LED' bit in the auxmode register
of the Broadcom BCM5201 PHY on the LinkSys USB100TX adapter so that the
link LED correctly (lights up amber for 10mbps link, green for 100mbps
link).

Note that the sticker on the bottom of the adapter says amber for 10
and green for 100, but the appendix in the manual that comes with
the adapter says green for 10 and amber for 100. Given that there doesn't
seem to be any way to make the hardware produce the latter combination,
I think it's safe to say the sticker is right and the manual is wrong.
I'm just shocked, shocked I tell you.

0177987224 Add device driver support for USB ethernet adapters based on the CATC
USB-EL1202A chipset. Between this and the other two drivers, we should
have support for pretty much every USB ethernet adapter on the market.
The only other USB chip that I know of is the SMC USB97C196, and right
now I don't know of any adapters that use it (including the ones made
by SMC :/ ).

Note that the CATC chip supports a nifty feature: read and write combining.
This allows multiple ethernet packets to be transfered in a single USB
bulk in/out transaction. However I'm again having trouble with large
bulk in transfers like I did with the ADMtek chip, which leads me to
believe that our USB stack needs some work before we can really make
use of this feature. When/if things improve, I intend to revisit the
aue and cue drivers. For now, I've lost enough sanity points.

502c509ce0 Apply the same netisr mechanism to transmissions as well. In order to
drive the transmitter, we have to check the interface's send queue in the
TX end of frame handler (i.e. the usb bulk out callback) and push out new
transmissions if the queue has packets in it and the transmitter is
ready. But the txeof handler is also called from a USB callback running
at splusb() too.

Grrr.

a0067d7b89 Attempt to fix a problem with receiving packets on USB ethernet interfaces.
Packets are received inside USB bulk transfer callbacks, which run at
splusb() (actually splbio()). The packet input queues are meant to be
manipulated at splimp(). However the locking apparently breaks down under
certain circumstances and the input queues can get trampled.

There's a similar problem with if_ppp, which is driven by hardware/tty
interrupts from the serial driver, but which must also manipulate the
packet input queues at splimp(). The fix there is to use a netisr, and
that's the fix I used here. (I can hear you groaning back there. Hush up.)

The usb_ethersubr module maintains a single queue of its own. When a
packet is received in the USB callback routine, it's placed on this
queue with usb_ether_input(). This routine also schedules a soft net
interrupt with schednetisr(). The ISR routine then runs later, at
splnet, outside of the USB callback/interrupt context, and passes the
packet to ether_input(), hopefully in a safe manner.

The reason this is implemented as a separate module is that there are
a limited number of NETISRs that we can use, and snarfing one up for
each driver that needs it is wasteful (there will be three once I get
the CATC driver done). It also reduces code duplication to a certain
small extent. Unfortunately, it also needs to be linked in with the
usb.ko module in order for the USB ethernet drivers to share it.

Also removed some uneeded includes from if_aue.c and if_kue.c

in the company list at all. Furthermore, this same vendor ID crops
up in some of the D-Link .INF files. Frankly I don't know what the heck
is going on here, but I need to add 0x66b to usbdevs and call it
something, so here we are.

dd3e57dac6 Be a bit more discriminating when trying to decide when to screen out
certain PHY addresses in aue_miibus_readreg(). Not all adapters based
on the Pegasus chip may have their PHYs wired for the same MII bus
addresses: the logic that I used for my ADMtek eval board might not
apply to other adapters, so make sure to only use it if this is really
an ADMtek eval board (check the vendor/device ID).

This will hopefully make the LinkSys USB100TX adapter work correctly.

6998849dc4 Do not attempt to load the firmware a second time. If you reboot your
machine but leave your KLSI adapter plugged into your USB port, it
may stay powered on and retain its firmware in memory. Trying to load
the firmware again in this case will wedge the chip. Try to detect this
in the kue_load_fw() routine and bail if the firmware is already
loaded and running.

Also, in the probe/match routine, force the revision code to the
hardware default and force a rescan of the quirk database. This is
necessary because the adapter will return a different revision code
if the firmware has been loaded. Without the firmware, the revision
code is 0x002. With the firmware, the revision code is 0x202. This
confuses the quirk mechanism, which won't match a quirk to a device
unless the revision code agrees with the quirk table entry.

This makes probe/attach of these devices somewhat more reliable.

Also add a few comments about the device's operation.

half-duplex only, so there's miibus or ifmedia support. This device
also requires firmware to be loaded into it, however KLSI allows
redistribution of the firmware images (I specifically asked about
this; they said it was ok).

ed63a7aaef This commit adds device driver support for the ADMtek AN986 Pegasus
USB ethernet chip. Adapters that use this chip include the LinkSys
USB100TX. There are a few others, but I'm not certain of their
availability in the U.S. I used an ADMtek eval board for development.
Note that while the ADMtek chip is a 100Mbps device, you can't really
get 100Mbps speeds over USB. Regardless, this driver uses miibus to
allow speed and duplex mode selection as well as autonegotiation.
Building and kldloading the driver as a module is also supported.

Note that in order to make this driver work, I had to make what some
may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer()
function will use tsleep() for synchronous transfers that don't complete
right away. This is a problem since there are times when we need to
do sync transfers from an interrupt context (i.e. when reading registers
from the MAC via the control endpoint), where tsleep() us a no-no.
My hack allows the driver to have the code poll for transfer completion
subject to the xfer->timeout timeout rather that calling tsleep().
This hack is controlled by a quirk entry and is only enabled for the
ADMtek device.

Now, I'm sure there are a few of you out there ready to jump on me
and suggest some other approach that doesn't involve a busy wait. The
only solution that might work is to handle the interrupts in a kernel
thread, where you may have something resembling a process context that
makes it okay to tsleep(). This is lovely, except we don't have any
mechanism like that now, and I'm not about to implement such a thing
myself since it's beyond the scope of driver development. (Translation:
I'll be damned if I know how to do it.) If FreeBSD ever aquires such
a mechanism, I'll be glad to revisit the driver to take advantage of
it. In the meantime, I settled for what I perceived to be the solution
that involved the least amount of code changes. In general, the hit
is pretty light.

Also note that my only USB test box has a UHCI controller: I haven't
I don't have a machine with an OHCI controller available.

Highlights:

- Updated usb_quirks.* to add UQ_NO_TSLEEP quirk for ADMtek part.

c0cdcd0b3e Fix one bug and make one minor enhancement:
- In uhci_intr() check to see if sc->sc_bus.bdev is NULL, and if it is,
  ack any pending interrupts and disable them, then return. It is possible
  for interrupts to be delivered the moment a handler is set up at attach
  time in uhci_pci.c, particularly when attempting to kldload the usb.ko
  module after the system is already up. However the driver isn't ready
  to field interrupts at that time and certain pointers in the softc
  struct aren't initialized yet, and we invariably end up falling off
  the end of one of them. The effect is that kldloading the usb module
  will panic the system in uhci_intr(). This added sanity check stops
  this from happening: I can now kldload the usb.ko module without any
  problems and load/attach other USB drivers after it.

  Of course the uhci driver has no detach method, but that's another
  problem.

- In uhci_run(), set the UHCI_CMD_MAXP bit in the command register to
  allow 64-byte packets to be used for full speed bandwidth reclamation.
  Certain high speed devices (in this case the ADMtek USB ethernet
  adapter) require this bit to be set, otherwise babble errors occur
  at the end of large (between 1100 and 1500 byte) transfers. This
  should not affect other devices, although supposedly it is less efficient
  than the 32-byte setting. Unfortunately, this is a per-bus setting,
  not a per-device setting, so we can't just enable it for certain
  devices on the USB bus.

fe0d408987 Remove the 'ivars' arguement to device_add_child() and
device_add_child_ordered().  'ivars' may now be set using the
device_set_ivars() function.

This makes it easier for us to change how arbitrary data structures are
associated with a device_t.  Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.

Despite my best efforts I've probably forgotten something so let me know
if this breaks anything.  I've been running with this change for months
and its been quite involved actually isolating all the changes from
the rest of the local changes in my tree.

b47337d347 Fix the 'usb0: USB revision unknown, not supported' people have been seeing
by identifying the version in the PCI drivers.

The OHCI driver just presets this to 1.0 as it is not specified in the
PCI registers anywhere. This should be revisited once USB 2.0 is in
wide spread use.

1d7490cce6 In one queue all the TDs (transfer descriptor, packets) for one transfer
are queued.  Traverse the queues vertically and then horizontally.
This means that TDs for one xfer are transmitted back to back until the
first NAK or error condition. Up to now we transmitted a TD per frame
and transmitted the next TD in the next frame.

The old approach is more fair if you have the end of the queue point at
the beginning of the control transfer queue, but also a lot more overhead
due to the fact that the QHs have to be read more often.

The new approach squirts the packets down the line as fast as possible
for one transfer and then does the next one. In the current situation,
with fairly empty USB buses, this is a more sensible approach. We might
have to revisit the scheduler later however.

It speeds up large transfers (Zip drive, Host-To-Host adapters) on UHCI
by a factor of 5 and makes it as fast as OHCI on the bus.

The next problem to solve is the question why the limit is 300kb/s and
not 1000/kb/s (kb == kilobyte).

Cleaning up the code:
- Declare many functions static
- Change variable names to make them more self explanatory
- Change usbd_request_handle -> usbd_xfer_handle
- Syntactical changes
- Remove some unused code
- Other KNF changes

Interrupt context handling
- Change delay to usbd_delay_ms were possible (takes polling mode into
  account)
- Change detection mechanism for interrupt context

Add support for pre-allocation DMA-able memory by device driver

Add preliminary support for isochronous to the UHCI driver (not for OHCI
yet).

usb.c, uhci.c, ohci.c
- Initial attempt at detachable USB host controllers
- Handle the use_polling flag with a lttle more care and only set it if
we are cold booting.

usb.c, uhci.c ohci.c, usbdi.c usbdi_util.c usb_subr.c
- Make sure an aborted pipe is marked as not running.
- Start queued request in the right order.
- Insert some more DIAGNOSTIC sanity checks.
- Remove (almost) unused definitions USBD_XFER_OUT and USBD_XFER_IN.

usb.c, usb_subr.c
- Add an event mechanism so that a userland process can watch devices
  come and go.

ohci.c
- Handle the case when a USB transfer is so long that it crosses two
  page (4K) boundaries.  OHCI cannot do that with a single TD so we make
  a chain.

ulpt.c
- Use a bigger buffer when transferring data.
- Pre-allocate the DMA buffer.  This makes the driver slightly more
  efficient.
- Comment out the GET_DEVICE_ID code, because for some unknown reason it
  causes printing to fail sometimes.

usb.h
- Add a macro to extract the isoc type.
- Add a macro to check whether the routine has been entered after splusb
  and if not, complain.

usbdi.c
- Fix a glitch in dequeueing and aborting requests on interrupt pipes.
- Add a flag in the request to determine if the data copying is done by
  the driver or the usbdi layer.

condition for Short transfers.

Change the scheduling to Depth first. We now transfer as many TD's as

still be verified that this does not lead to starvation in a busy system
(in the case were transfers are added to the beginning of the control
or bulk queues).

0b0f3f6c3d The Qtronix keyboard has a built in PS/2 port for a mouse.
It however posts a bogus button up event once in a while. Whenever
we receive dx=dy=dz=buttons=0 we postpone adding it to the queue for
50msecs with a timeout. If in the meantime something else is posted
the event is ignored.

This avoids the problem Nik Sayer reported. He noticed that X windows
would drop and pick up a window once in a while.

Thanks, Nik, for supplying me with the keyboard to fix the problem!
