 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
augustss b14b78dfc9 Deallocate resources (bus space and interrupts) when detaching from 
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

be necessary, but without some machines don't work.
 1998-12-28 12:56:19 +00:00

Using the bus_dma functions directly is inefficient.
