thorpej fc96443d15 New callout mechanism with two major improvements over the old 
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

augustss eb6e78ce98 Make sure all packets (except the last) have the maximum packet size even 
when using multiple TDs.
 2000-03-20 00:37:00 +00:00
augustss 9762d78a52 Make control transfer of over 8K possible by using a chain of TDs. 2000-03-19 22:24:57 +00:00
tsutsui 6e0e3d609f Replace LE() macro with le32toh()/le32toh(). 2000-03-16 12:40:51 +00:00
augustss 1a9f0619fd Fix thinko in the handling of FORCE_SHORT_XFER so that it actually 
transfers a 0 length package instead on munging the whole transfer.
The aue driver works now.
 2000-03-16 00:41:50 +00:00
augustss 7d05674ba7 Distinguish between device and interface classes. 
(I finally found a document that said that they were different.)
 2000-02-29 21:37:00 +00:00
augustss 9651e60835 Fix typos in my last commit that caused the driver to panic. 
Change some (unrelated) debug messages.
 2000-02-22 22:59:49 +00:00
augustss 9056664327 Prepare a little for having USB interrupt processing done outside the hard 
interrupt level (in a thread or a softintr).
No real soft processing done yet.
 2000-02-22 11:30:54 +00:00
augustss 6393288539 Put some #ifdefs around power and shutdown hooks. 2000-02-01 05:42:52 +00:00
augustss daa36b1b58 Rename TAILMASK to HEADMASK, since it really masks the head pointer. 
From FreeBSD.
 2000-01-31 22:35:13 +00:00
augustss cc46ffeb91 Change where the has table for physical-to-virtual address translation 
is handled.  Partly from FreeBSD.
 2000-01-31 22:09:13 +00:00
augustss ae4bbc4485 Fiddle with over-current protect when turning on port power to make 
things work for some OHCI controllers.
 2000-01-31 20:17:25 +00:00
augustss ef79cf035a Correct error message list. From Nick Hibma. 2000-01-28 13:32:55 +00:00
augustss 119272426a Fix typo. From Nick Hibma. 2000-01-28 10:19:48 +00:00
augustss f0ebd281e5 Add done method for root control transfers. 2000-01-25 12:06:21 +00:00
augustss c3716a6bb9 Add an argument to usbd_open_pipe_intr() to specify the polling interval 
for an interrupt pipe in case we don't what what the descriptor suggests.
 2000-01-19 00:23:58 +00:00
augustss 21863071b1 Move the zeroing of the xfer to the individual methods. 2000-01-18 20:23:42 +00:00
augustss f14036861f Turn xfer allocation into a method in the HC driver. The reason is that 
an HC driver may want to subclass the xfer to have additional private fields.
 2000-01-18 20:11:00 +00:00
augustss 537c04e5ee Add a flag, USBD_FORCE_SHORT_XFER, to transfers. Using this flag will 
force the last packet of a transfer to be smaller than the maximum
packet size.  The only time this matters is if the transfer size is
a multiple of the maximum packet size, in which case a 0 length packet
is sent last.
Some weird devices require this behaviour to determine the end of
a transfer.
 2000-01-16 13:12:05 +00:00
augustss 9e5ce08183 Add framework for doing isoc transfers. The actual scheduling code 
is still missing.
 2000-01-16 10:35:24 +00:00
augustss 1a080201cc Add shutdown hooks to ensure that the host controller is halted when 
a reboot occurs.
 2000-01-16 10:27:51 +00:00
augustss 8111aaeef9 Cosmetics and a couple of diagnostic messages. 1999-12-06 21:06:59 +00:00
augustss b687c3c859 Some more DIAGNOSTIC. 1999-12-01 23:19:11 +00:00
augustss 7b92ed07bd Propagate the USB revision number to the usb driver. 1999-11-20 00:57:08 +00:00
augustss 3386c68b46 Cosmetic changes and some small improvements. From FreeBSD and Nick Hibma. 1999-11-18 23:32:25 +00:00
augustss cdaec29859 A few more purely stylistic changes that I missed in the last round. 1999-11-17 23:00:49 +00:00
augustss 0d2fabdf26 A number of stylistic changes to increase readability (many suggested 
by Nick Hibma):
	use NULL not 0
	declare all local definitions static
	rename s/usbd_request/usbd_xfer/ s/reqh/xfer/
	rename s/r/err/
	use implicit test for no err
	KNF
 1999-11-12 00:34:57 +00:00
augustss 03a522d3c1 Merge in a large batch of changes from Nick Hibma <hibma@skylink.it> so 
the USB stack compiles on FreeBSD again.
 1999-10-13 08:10:55 +00:00
augustss 11403b6ec1 Fix some bugs in USB controller detach code. 1999-10-12 20:02:47 +00:00

the bus.
 1999-10-12 11:21:24 +00:00
augustss fb7795c908 Make sure the HC deactivation is propagated. 1999-09-18 11:25:50 +00:00
augustss 2557320246 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.
 1999-09-15 21:14:03 +00:00
augustss 7049e8eb1b Add preliminary (untested) code for detaching the USB host controller 
(needed for CardBus based controllers).
 1999-09-15 10:25:30 +00:00
augustss ba2c2e2ade * Make sure an aborted pipe is marked as not running. 
* Start queued request in the right order.
* Insert some more DIAGNOSTIC sanity checks.
 1999-09-13 21:33:25 +00:00
augustss bc5da9a8da Make sure timeouts count as interrupt context too. 1999-09-13 19:49:41 +00:00
augustss ff6a476e6c Rearrange the code a little so we can decide if we are in process 
or interrupt context in a reliable way.  Mainly used for DIAGNOSTIC.
 1999-09-13 19:18:17 +00:00
augustss 98b6524413 * Move DMA buffer allocation to HC independent code. 
* Remove (almost) unused definitions USBD_XFER_OUT and USBD_XFER_IN.
 1999-09-11 08:19:26 +00:00
augustss 2aadcb5f47 Change the internal API to allow DMA buffers to be pre-allocated by 
the device driver instead of happening automagically in the HC driver.
This affects both the HC-USBD interface as well as the USBD-device
interface.
This change will allow DMA buffers to be reused e.g. in isochronous
traffic.

Add isochronous support to the UHCI driver (not for OHCI yet).
 1999-09-09 12:26:43 +00:00
augustss 2425433ff6 Change some printf to DPRINTF for consistency. From Nick Hibma, FreeBSD. 1999-09-05 21:22:38 +00:00
augustss f3421bec94 Change the way the direction is extracted from the endpoint descriptor. 
No functional changes to the drivers.  From Nick Hibma, FreeBSD.
 1999-09-04 22:26:11 +00:00
augustss 4c217fdaf8 Merge the soft_{td,ed} with the real {td,ed}. This saves time and space. 
(And fix typo in corresponding uhci change.)
 1999-08-22 23:41:00 +00:00
augustss f747201099 Move more of the transfer completion processing to HC independent code. 
Fix some problems with transfer abort & timeout.
 1999-08-22 20:12:39 +00:00
augustss 54adf47f36 Redo the UHCI data toggle handling. 
Make sure data toggles get synchronized on open and
when clearing an endpoint stall.
 1999-08-17 20:59:04 +00:00
augustss 3016e1ebe0 Make some small changes to make it compile on OpenBSD. 1999-08-17 16:06:20 +00:00
augustss 290c03447b Change the way transfers are dequeued so thet we know that they 
are removed from the queue before being deallocated.
 1999-08-16 20:24:33 +00:00
augustss b23490d39f Implement timeout and abort of requests. 
Compute length of short transfers correctly.
 1999-08-14 08:56:09 +00:00
augustss b177c7a397 Totally redo the way device detach is done. It now uses a kernel event 
thread and the config detach method.
Squish a number of space leaks on detach.
 1999-06-30 06:44:22 +00:00
augustss 2959234be5 Fix a bug in bulk input. Discovered by Joel Chen <jchen@liberate.com>. 1999-06-09 22:57:16 +00:00
wrstuden cd0a68c3f6 Fix use of & when % was appropriate. 1999-06-09 19:40:54 +00:00
