6a6fdc8681 Kill SPLUSBCHECK -- it's not portable, and quite annoying on some 
platforms which otherwise function just fine.

ed9486e158 Bring the coding style into the 80s, i.e., get rid of __P and use 
ANSI prototypes and declarations.

0069eba19b Some cleanup and renaming of the callouts used in USB drivers. 2000-03-24 22:03:28 +00:00

fc96443d15 New callout mechanism with two major improvements over the old 
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

9056664327 Prepare a little for having USB interrupt processing done outside the hard

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.

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

ff6a476e6c Rearrange the code a little so we can decide if we are in process

98b6524413 * Move DMA buffer allocation to HC independent code.

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

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.

011be0080e Add vendor/product/release locators. Added in frustration as my HID 
devices appeared as different devices after some plugging and unplugging. :-)

0d0cc4aa14 Rework the way ukbd attaches itself as the console (again). We now allow 
the code to pick the first USB keyboard instance as the console, ignoring
which USB controller it's on.  Should eventually allow detaching of the
console keyboard.

375d7c32f2 Add a way for machine-dependent code to tell a USB controller that it 
has the console input device.  The USB keyboard driver uses this to
attach the first USB keyboard instance as the console keyboard.

Unfortunately, this must still be deferred to autoconfiguration time,
but there's not much we can do about that right now.
