* Merge recent USB2/EHCI related changes from NetBSD:Ian Dowse2004-11-031-4/+44
| | | | | | | | | | | | | | | | | | | o Reduce the interrupt delay to 2 microframes. o Follow the spec more closely when updating the overlay qTD in the QH. o No need to generate an interrupt at the data part of a control transfer, it's generated by the status transfer. o Make sure to update the data toggle on short transfers. o Turn the printf about needing toggle update into a DPRINTF. o Keep track of what high speed port (if any) a device belongs to so we can set the transaction translator fields for the transfer. o Verbosely refuse to open low/full speed pipes that depend on unimplemented split transaction support. o Fix various typos in comments.

* Next step in making usb more newbus:Warner Losh2004-08-141-26/+14
| | | | | | | | | | | | | | | | o reprobe children when a new driver is added to uhub o fix the usbd_probe_and_attach to set the ivars to a malloc'd area, as well as freeing the ivars on child destruction. o Don't delete children that don't attach. Evidentally, the need to do this is a common misconception. o minor formatting foo that may violate style(9) at the moment, but keeps the diffs against my p4 tree smaller. This does not solve the ugen gobbling things up problem, but the fixes I have for that expose bugs in other parts of the tree... Notes: svn path=/head/; revision=133730

* More USB ethernet tweaks:Bill Paul2000-01-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Sync ohci, uhci and usbdi modules with NetBSD in order to obtain the following improvements: o New USBD_NO_TSLEEP flag can be used in place of UQ_NO_TSLEEP quirk. This allows drivers to specify busy waiting only for certain transfers (namely control transfers for reading/writing registers and stuff). o New USBD_FORCE_SHORT_XFER flag can be used to deal with devices like the ADMtek Pegasus that sense the end of bulk OUT transfers in a special way (if a transfer is exactly a multiple of 64 bytes in size, you need to send an extra empty packet to terminate the transfer). o usbd_open_pipe_intr() now accepts an interval argument which can be used to change the rate at which the interrupt callback routine is invoked. Specifying USBD_DEFAULT_INTERVAL uses the value specified in the device's config data, but drivers can override it if needed. - Change if_aue to use USBD_FORCE_SHORT_XFER for packet transmissions. - Change if_aue, if_kue and if_cue to use USBD_NO_TSLEEP for all control transfers. We no longer force the non-tsleep hack for bulk transfers since these are done asynchronously anyway. - Removed quirk entry fiddling from if_aue and if_kue since we don't need it anymore now that we have the USBD_NO_TSLEEP flag. - Tweak ulpt, uhid, ums and ukbd drivers to use the new arg to usbd_open_pipe_intr(). - Add a flag to the softc struct in the ethernet drivers to indicate when a device has been detached, and use this flag to perform tests to prevent the drivers from trying to do control transfers if this is the case. This is necessary because calling if_detach() with INET6 enabled will eventually result in a call to the driver's ioctl() routine to delete the multicast groups on the interface, which will result in attempts to perform control transfers. (It's possible this also happens even without INET6 support enabled.) This is pointless since we know that if the detach method has been called, the hardware has been unplugged. - Changed watchdog timeout routines to just call the driver init routines to initialize the device states without trying to close and re-open the pipes. This is partly because we don't want to frob things at interrupt context, but also because this doesn't seem to work right and I don't want to panic the system just because a USB device may have stopped responding. - Fix aue_rxeof() to be a little smarter about detecting when a double transfer is needed. Unfortunately, the design of the chip makes it hard to get this exactly right. Hopefully, this will go away once either Nick or Lennart finds the bug in the uhci driver that makes this ugly hack necessary. - Also sync usbdevs with NetBSD. Notes: svn path=/head/; revision=56318

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.
