augustss c6ddc6009b Make it compile with USB_DEBUG. 2000-06-01 15:51:26 +00:00
augustss ed9486e158 Bring the coding style into the 80s, i.e., get rid of __P and use 
ANSI prototypes and declarations.
 2000-06-01 14:28:57 +00:00
augustss 18cd73168e Be more careful when setting the alternate interface so we don't end up with 
nothing set at all if it fails.

augustss 30c20f930f Change my email address. 2000-04-27 15:26:44 +00:00

augustss 9609f4caa2 Add a comment. 2000-03-28 09:48:25 +00:00
augustss fc72e72d7d Change (almost) all static to Static. The symbol `Static' can then be defined 
to `' or `static' depending on if you want to debug or not.
 2000-03-27 12:33:53 +00:00
augustss 3fded57690 Rename and move around callout handles to make it more sane. 
Add some DIAGNOSTIC.
Fix buglet in isoc abort on UHCI.
 2000-03-25 18:02:32 +00:00

thorpej 6a6358ed5c Shake out some bugs from the callout changes. 2000-03-23 18:59:10 +00:00
augustss e0d3ede01c Get the status right when a polled transfer times out. 2000-03-08 15:34:10 +00:00
augustss 2dda67d4a2 Fix typo in argument to ratecheck(). 2000-03-02 15:49:29 +00:00
augustss d6c4ac7ff2 Use ratecheck() to limit error messages on disconnect. 
Break out some common functionality.
 2000-03-02 12:37:50 +00:00
augustss 76c14cd322 Don't stall the control pipe on error. 2000-02-08 18:46:03 +00:00
augustss 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.
 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 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.
 2000-01-16 23:11:43 +00:00
augustss 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().
 2000-01-16 13:22:18 +00:00
augustss c664f35fc5 Let usbd_set_polling() work on a usbd_device_handle instead of 
a usbd_interface_handle.
 2000-01-16 09:37:18 +00:00

augustss 77bb4d8ce2 Cosmetic change. 1999-11-26 01:40:01 +00:00

augustss ffb29861c2 Add a few more diagnostics. 1999-11-16 22:19:03 +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

augustss 1e35ed7989 Temporarily disable a DIAGNOSTIC. 1999-10-13 14:28:07 +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 df435c83b2 Add an event mechanism so that a userland process can watch devices come 
and go.
 1999-10-12 11:54:56 +00:00
augustss 5260cadff2 Add a sanity check to the computed actual transfer length. 1999-09-15 21:08:59 +00:00
augustss e54df1b10c Handle the use_polling flag with a lttle more care and only set it if 
we are cold booting.
 1999-09-15 14:17:14 +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 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 b1a719a6cc Add a flag in the request to determine if the data copying is done by the 
driver or the usbdi layer.
 1999-09-12 08:23:42 +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 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.
 1999-09-05 19:32:18 +00:00
augustss 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.
 1999-08-23 22:55:14 +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 b8b1e35ece Some changes from FreeBSD (no functional differences). 1999-08-14 14:49:31 +00:00
