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 009856b631 Save and restore a couple ofregisters in the power hook in case BIOS doesn't. 2000-02-22 16:03:42 +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 30f0efb4f2 Add uhci_root_ctrl_done() method. 2000-01-28 00:44:27 +00:00
augustss 4e9e8e52f4 Change the test to check if transfers are done. The old test was broken 
and sometimes reported transfers as done prematurely.
This fix seems to stabilize the Ethernet drivers.
 2000-01-28 00:15:54 +00:00
augustss 57d2439d74 Try to avoid accessing the HC if it is dead. Suggested by mycroft. 2000-01-26 10:04:38 +00:00
augustss b9a4fe55b5 Switch the HSE and HCPE messages. Pointed out my mycroft. 2000-01-25 17:31:05 +00:00
augustss 55c5d10627 Fix typos. 
Never, never, never commit without compiling first.
 2000-01-19 01:16:38 +00:00
augustss fe18229923 Obey the interrupt interval here also. 2000-01-19 01:04:26 +00:00
augustss a97cf3f9ce Fix a buglet in framelist locking. 2000-01-19 01:02:11 +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 ed1996fc7d Be a little more talkative on with UHCIDEBUG on errors. 2000-01-17 01:01:07 +00:00
augustss 2b8a0e9b1c Remove some debug code that was commited by mistake. 2000-01-16 13:14:43 +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 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 6e2f22c70f Turn on the MAXP bit in the controller to allow 64 byte packets at 
the end of a frame.
 1999-12-24 13:56:35 +00:00
augustss 8111aaeef9 Cosmetics and a couple of diagnostic messages. 1999-12-06 21:06:59 +00:00
augustss b15fcce56c Use vertical nscheduling for bulk traffic. It improves bulk thruput a lot. 
From FreeBSD and Nick Hibma.
 1999-12-01 00:42:05 +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 a28e3fec43 Fix PR8666, to verbose diagnostics. 1999-10-23 00:21:01 +00:00

(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 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

 1999-08-19 19:52:38 +00:00
augustss 54adf47f36 Redo the UHCI data toggle handling.

 1999-06-30 06:44:22 +00:00
augustss 3fd5344a95 Add suspend/resume handling to the UHCI driver.
