76c14cd322 Don't stall the control pipe on error. 2000-02-08 18:46:03 +00:00

c9aa323521 Change the way the HC done method is invoked a little. 2000-01-31 20:13:07 +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.

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.

cc381bcb7c Add usbd_reload_device_desc() to get the device descriptor again from a device. 
Useful if e.g. downloading firmware updates the revision number.

67ad556c60 Get timeout right in the gruesome hack. 2000-01-16 13:34:51 +00:00
augustss
eb7268f16c XXX Add a temporary, gruesome hack. It allows transfers to 
XXX be done using delay() instead of tsleep().
XXX This enables transfers to be made from an interrupt context, which
XXX is needed until some more threads are added to the kernel.
XXX Using this hack (which is rare) causes the kernel to busy-wait
XXX for up to 1 ms at splusb().

c664f35fc5 Let usbd_set_polling() work on a usbd_device_handle instead of 
a usbd_interface_handle.

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

df435c83b2 Add an event mechanism so that a userland process can watch devices come 
and go.

7049e8eb1b Add preliminary (untested) code for detaching the USB host controller 
(needed for CardBus based controllers).

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

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

b1a719a6cc Add a flag in the request to determine if the data copying is done by the 
driver or the usbdi layer.

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

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).

24251055bc Change the way the `struct device' base part of all driver softc are 
declared and accessed to make it more portable.  Idea from Nick Hibma, FreeBSD.
No functional changes.

1aa63c9fab Add some comments. 1999-08-28 10:04:01 +00:00
augustss
1f2661798f Make sure to mark the device as dying already in the (de)activate routine. 
This avoids access to it before the detach routine has blown it away.

f747201099 Move more of the transfer completion processing to HC independent code. 
Fix some problems with transfer abort & timeout.

54adf47f36 Redo the UHCI data toggle handling. 
Make sure data toggles get synchronized on open and
when clearing an endpoint stall.

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.

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.

475ed73e46 Get rid of a bunch of code that was part of an old USBDI proposal, but that 
is unused in our USB stack.

Once upon a time, when I started writing the USB stack for NetBSD, there
was an effort to make a standard for how USB device drivers should interact
with the rest of the USB stack.  This effort had contributors from just
about all Un*x camps (but not Micro$oft :).  I based my design on one of their
early proposals since I thought it would be a good idea if we could all
share device drivers with a minimum effort.  Shortly after I started my work
all the free Un*x people were thrown out of the USBDI work since we did not
pay the USB membership fee.  Well, some time has passed now and the work of
the standardization group is almost public again.  But alas, the new standard
has grown to be a monster!  I do not want to have this as the basis for the
*BSD USB stack; it is far too complicated.
So, since we are not even close to being compilant with the standard, I've
thrown out some old baggage.
