1767c08cba Add a capability for pre/post processing on write/read. 2000-04-14 14:21:55 +00:00

a302716de4 Let the parent device of a ucom decide what size the read and write 
buffers should be since it knows about the speed.
Increase the buffer size of uvisor.
XXX The uvisor is still pitifully slow.  There must be a problem somewhere.

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.

7d05674ba7 Distinguish between device and interface classes. 
(I finally found a document that said that they were different.)

a2b1ac707a Split the umodem driver into two parts: the part that emulates a tty over 
two bulk pipes, and the setup and status fiddling goo.
This allows the former part to be shared by other drivers that need to
look like a tty.

97fc004770 Don't complain when umodemstartread() returns USBD_IN_PROGRESS. It's normal. 1999-11-26 09:12:50 +00:00

982eb1b4e6 Preallocate DMA buffers. Fixes problem reported by Hubert Feyrer. 1999-11-16 10:21:11 +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

98b6524413 * Move DMA buffer allocation to HC independent code. 
* Remove (almost) unused definitions USBD_XFER_OUT and USBD_XFER_IN.

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.

aa7264892d Implement a modem driver for the Abstract Control Model, i.e. AT commands. 
It is accessible through the usual tty abstraction.
XXX The driver needs better error handling and a special call device.
XXX It also needs more testing.

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.

diffs from Nick Hibma <n_hibma@freebsd.org>, but with substantial
changes from me.
