* MFC r277136:Hans Petter Selasky2015-02-051-0/+40
| | | | | | | | | | | | | Resolve a special case deadlock: When two or more threads are simultaneously detaching kernel drivers on the same USB device we can get stuck in the "usb_wait_pending_ref_locked()" function because the conditions needed for allowing detach are not met. While at it ensure that "flag_iserror" is only written when "priv_mtx" is locked, which is protecting it. Notes: svn path=/stable/9/; revision=278291

| | | | | | | | | | | | | | Resolve a deadlock setting the USB configuration index from userspace on USB HUBs by moving the code into the USB explore threads. The deadlock happens because child devices of the USB HUB don't have the expected reference count when called from outside the explore thread. Only the HUB device itself, which the IOCTL interface locks, gets the correct reference count. Approved by: re, marius @ Notes: svn path=/stable/9/; revision=267350

| | | | | | | | | | | | | | | | | - Move scratch data from the USB bus structure to the USB device structure so that simultaneous access cannot happen. Protect scratch area using the enumeration lock. - Reduce stack usage in usbd_transfer_setup() by moving some big stack members to the scratch area. This saves around 200 bytes of stack. - Fix a whitespace. - Protect control requests using the USB device enumeration lock. - Make sure all callers of usbd_enum_lock() check the return value. - Remove the control transfer specific lock. - Bump the FreeBSD version number, hence external USB modules may need to be recompiled due to a USB device structure change.

| | | | | | | | | | | | | | | | | | | 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.

* MFp4 @ 168387Andrew Thompson2009-09-281-4/+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 Notes: svn path=/head/; revision=197553

* Make the newbus subsystem Giant free by adding the new newbus sxlock.Attilio Rao2009-08-021-21/+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.

| | | | | | | | | | | | | | | | - 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.
