This commit was manufactured to restore the state of the 4.1-RELEASE image. Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs. 2000-07-02T11:27:27Z Nick Hibma n_hibma@FreeBSD.org 2000-07-02T11:27:27Z urn:sha1:42656335a4424bb7af2e41d840cac7319d229764 e-mail address 2000-05-07T14:39:59Z Nick Hibma n_hibma@FreeBSD.org 2000-05-07T14:39:59Z urn:sha1:0dd39cc3d0fe7df37139002013c118e2ceafa653 2000-05-07T14:22:47Z Nick Hibma n_hibma@FreeBSD.org 2000-05-07T14:22:47Z urn:sha1:bfaaf3763588905a5f69274d7ffcaefa99e1ce76 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. 1999-11-08T21:06:21Z Nick Hibma n_hibma@FreeBSD.org 1999-11-08T21:06:21Z urn:sha1:24b4921ad1605bc510017d196108e5455b76d59b Pushed-By: phk 1999-10-07T19:26:38Z Nick Hibma n_hibma@FreeBSD.org 1999-10-07T19:26:38Z urn:sha1:8c895d718bc84906595ec78a743085ea713ebd89 - Some cleanup and improvements in the uhci and ohci drivers - Support for plugging and unplugging devices improved - Now available is bulk transport over OHCI controllers - Resume and suspend have been temporarily been disabled again. Proper support for it is available in the uhci.c and ohci.c files but I have not yet spent the brain cycles to use it. - OpenBSD now uses the USB stack as well - Add FreeBSD tags 1999-04-11T20:50:33Z Nick Hibma n_hibma@FreeBSD.org 1999-04-11T20:50:33Z urn:sha1:67aa00a71bb06d52675f0801d00d23cb37e30e06 2) create function usbd_errstr which turns a usbd_status into a sensible error message 3) Change the printf in DPRINTF to logprintf which is a define for log(KERN_DEBUG, x) 1999-01-22T00:51:12Z Nick Hibma n_hibma@FreeBSD.org 1999-01-22T00:51:12Z urn:sha1:235dddd4eaacdb94823b8041ddd5ba5cdd006388 1999-01-10T18:42:54Z Nick Hibma n_hibma@FreeBSD.org 1999-01-10T18:42:54Z urn:sha1:53809e8652486ac0a0a16e945598974c89401ad4
