freebsd/sys/dev/usb/usbdi.h
Nick Hibma 3241be7550 Synchronisation with NetBSD as of 1999/11/16: 
Cleaning up the code:
- Declare many functions static
- Change variable names to make them more self explanatory
- Change usbd_request_handle -> usbd_xfer_handle
- Syntactical changes
- Remove some unused code
- Other KNF changes

Interrupt context handling
- Change delay to usbd_delay_ms were possible (takes polling mode into
  account)
- Change detection mechanism for interrupt context

Add support for pre-allocation DMA-able memory by device driver

Add preliminary support for isochronous to the UHCI driver (not for OHCI
yet).

usb.c, uhci.c, ohci.c
- Initial attempt at detachable USB host controllers
- Handle the use_polling flag with a lttle more care and only set it if
we are cold booting.

usb.c, uhci.c ohci.c, usbdi.c usbdi_util.c usb_subr.c
- Make sure an aborted pipe is marked as not running.
- Start queued request in the right order.
- Insert some more DIAGNOSTIC sanity checks.
- Remove (almost) unused definitions USBD_XFER_OUT and USBD_XFER_IN.

usb.c, usb_subr.c
- Add an event mechanism so that a userland process can watch devices
  come and go.

ohci.c
- 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.

ulpt.c
- Use a bigger buffer when transferring data.
- Pre-allocate the DMA buffer.  This makes the driver slightly more
  efficient.
- Comment out the GET_DEVICE_ID code, because for some unknown reason it
  causes printing to fail sometimes.

usb.h
- Add a macro to extract the isoc type.
- Add a macro to check whether the routine has been entered after splusb
  and if not, complain.

usbdi.c
- Fix a glitch in dequeueing and aborting requests on interrupt pipes.
- Add a flag in the request to determine if the data copying is done by
  the driver or the usbdi layer.
