* Modify the FreeBSD USB kernel code so that it can be compiled directlyhselasky2013-01-301-1/+18
| | | | | | | | | | | | | | | | | | | | | | into the FreeBSD boot loader, typically for non-USB aware BIOSes, EFI systems or embedded platforms. This is also useful for out of the system compilation of the FreeBSD USB stack for various purposes. The USB kernel files can now optionally include a global header file which should include all needed definitions required to compile the FreeBSD USB stack. When the global USB header file is included, no other USB header files will be included by default. Add new file containing the USB stack configuration for the FreeBSD loader build. Replace some __FBSDID()'s by /* $FreeBSD$ */ comments. Now all USB files follow the same style. Use cases: - console in loader via USB - loading kernel via USB Discussed with: Hiroki Sato, hrs @ EuroBSDCon

* This commit adds full support for USB 3.0 devices in host and devicehselasky2010-10-041-0/+6
| | | | | | | | | | | | | | | | mode in the USB core. The patch mostly consists of updating the USB HUB code to support USB 3.0 HUBs. This patch also add some more USB controller methods to support more active-alike USB controllers like the XHCI which needs to be informed about various device state events. USB 3.0 HUBs are not tested yet, due to lack of hardware, but are believed to work. After this update the initial device descriptor is only read twice when we know that the bMaxPacketSize is too small for a single packet transfer of this descriptor. Approved by: thompsa (mentor)

* MFp4 @ 168387thompsa2009-09-281-4/+2
| | | | | | | | | | | | | | | | - clean up USB detach logic. There seems to be some problems detaching multiple USB HUBs connected in series from the root. - after this patch the rule is: 1) Always use device_detach() on the USB HUB first. 2) Never just device_delete_child() on the USB HUB, because that function will traverse to all the device leaves and free them first, and then the USB stack will free the devices twice which doesn't work very well. - make sure the did DMA delay gets set after the timeout has elapsed to make logic more clear. There is no functional difference. Submitted by: Hans Petter Selasky

* Make the newbus subsystem Giant free by adding the new newbus sxlock.attilio2009-08-021-21/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The newbus lock is responsible for protecting newbus internIal structures, device states and devclass flags. It is necessary to hold it when all such datas are accessed. For the other operations, softc locking should ensure enough protection to avoid races. Newbus lock is automatically held when virtual operations on the device and bus are invoked when loading the driver or when the suspend/resume take place. For other 'spourious' operations trying to access/modify the newbus topology, newbus lock needs to be automatically acquired and dropped. For the moment Giant is also acquired in some key point (modules subsystem) in order to avoid problems before the 8.0 release as module handlers could make assumptions about it. This Giant locking should go just after the release happens. Please keep in mind that the public interface can be expanded in order to provide more support, if there are really necessities at some point and also some bugs could arise as long as the patch needs a bit of further testing. Bump __FreeBSD_version in order to reflect the newbus lock introduction. Reviewed by: ed, hps, jhb, imp, mav, scottl No answer by: ariff, thompsa, yongari Tested by: pho, G.

| | | | | | | | | | | | Refactor how we interface with the root HUB. This is achieved by making a direct call from usb2_do_request to the host controller for root hub requests, this call will perform the controller specific register read/writes and return the error code. This cuts out a lot of code in the host controller files and saves one thread per USB bus. Submitted by: Hans Petter Selasky

* MFp4 //depot/projects/usb@159909thompsa2009-04-051-1/+14
| | | | | | | | | | | | | - make usb2_power_mask_t 16-bit - remove "usb2_config_sub" structure from "usb2_config". To compensate for this "usb2_config" has a new field called "usb_mode" which select for which mode the current xfer entry is active. Options are: a) Device mode only b) Host mode only (default-by-zero) c) Both modes. This change was scripted using the following sed script: "s/\.mh\././g". - the standard packet size table in "usb_transfer.c" is now a function, hence the code for the function uses less memory than the table itself.
