This commit was manufactured to restore the state of the 4.6.2-RELEASE image. Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs. 2000-10-31T23:23:30Z Nick Hibma n_hibma@FreeBSD.org 2000-10-31T23:23:30Z urn:sha1:c5eb68505f7d993f7c693ba2690280efbe2f0f6f 2000-07-02T11:44:00Z Nick Hibma n_hibma@FreeBSD.org 2000-07-02T11:44:00Z urn:sha1:2282bcf521d487f9f824f8637de3e4e191fffe16 2000-05-07T14:22:47Z Nick Hibma n_hibma@FreeBSD.org 2000-05-07T14:22:47Z urn:sha1:bfaaf3763588905a5f69274d7ffcaefa99e1ce76 2000-01-20T07:38:33Z Bill Paul wpaul@FreeBSD.org 2000-01-20T07:38:33Z urn:sha1:a6d9a40e8163f779fb153df81631a6ab9f441bb4 - 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. 1999-11-21T17:25:30Z Nick Hibma n_hibma@FreeBSD.org 1999-11-21T17:25:30Z urn:sha1:88ea580e343e33a62cd5847bf1c379064f6c5421 when moused was still running when the mouse was detached. Convert uhid to use make_dev while I am there. Ugen still needs to be converted. 1999-11-17T22:33:51Z Nick Hibma n_hibma@FreeBSD.org 1999-11-17T22:33:51Z urn:sha1:3241be755096a340cd6ba126b6d88e362ad03b71 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. 1999-11-08T23:58:33Z Nick Hibma n_hibma@FreeBSD.org 1999-11-08T23:58:33Z urn:sha1:0b0f3f6c3d53f48cf165b02ec19a85ed73a13c90 It however posts a bogus button up event once in a while. Whenever we receive dx=dy=dz=buttons=0 we postpone adding it to the queue for 50msecs with a timeout. If in the meantime something else is posted the event is ignored. This avoids the problem Nik Sayer reported. He noticed that X windows would drop and pick up a window once in a while. Thanks, Nik, for supplying me with the keyboard to fix the problem! 1999-11-08T07:44:01Z Poul-Henning Kamp phk@FreeBSD.org 1999-11-08T07:44:01Z urn:sha1:44d1184e81b347d864ad05c21b5c56b1a2f27376 Nagged about by: msmith 1999-11-08T07:10:48Z Peter Wemm peter@FreeBSD.org 1999-11-08T07:10:48Z urn:sha1:bda20b64e4cecefbaa90ecea08a7897a6d351362 (presently broken) DEV_DRIVER_MODULE().
