5e8cefc2ea Ad function to remove a usb task. 2001-01-23 17:04:30 +00:00
augustss
df20cb2972 Change the operation of the USB event thread. Before it only performed 
USB device discovery, now it can also perform (short) tasks for device
drivers that need a process context, but don't have one.
This is not pretty, but better than using busy-wait in an interrupt context.

e8db629494 Add code to use soft interrupt to handle USB interrupt processing. 
Don't enable the code since it doesn't work with the kludgy Ethernet drivers.

34bb7b9a35 Don't try to access a device that is being disconnected when generating 
the detach event.  Fixes (I hope) PR 11713 from itohy@netbsd.org (ITOH Yasufumi).

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

481e8339dc Change the USB event mechanism to include more information about devices 
and drivers.  Partly from FreeBSD.

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.

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.

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.

cdaec29859 A few more purely stylistic changes that I missed in the last round. 1999-11-17 23:00:49 +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

driver or the usbdi layer.

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

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.

04cd1cc8ee Make usbd_errstr() always return a useful error message; it's not like 
the strings are that big.

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

a0803787f7 Add functions to execute asynchronous requests and use these from

our kitty, jumped onto the USB keyboard the machine crashed.]
