* Use a different task queue for host controller and peripheral driverIan Dowse2006-10-191-1/+2
| | | | | | | | | | | | | | | tasks. Since the host controllers rely on tasks to process transfer timeouts, if a synchronous transfer from a driver was invoked from a task and timed out, it would never complete because the single task thread was stuck performing the synchronous transfer so couldn't process the timeout. This affected the axe, udav and ural drivers. Problem hardware provided by: guido Notes: svn path=/head/; revision=163493

| | | | | | | | | | | | | USBD_FORCE_SHORT_XFER to ensure that we actually build and execute a transfer. This means that the various alloc_sqtd_chain functions will always construct a transfer, so it is safe to modify the allocated descriptors on return. Previously there were cases where a zero length transfer would cause a NULL dereference. Reported by: bp Notes: svn path=/head/; revision=159024
* Use the limited scatter-gather capabilities of ehci, ohci and uhciIan Dowse2006-05-281-45/+219
| | | | | | | | | | | | | | | | | | host controllers to avoid the need to allocate any multi-page physically contiguous memory blocks. This makes it possible to use USB devices reliably on low-memory systems or when memory is too fragmented for contiguous allocations to succeed. The USB subsystem now uses bus_dmamap_load() directly on the buffers supplied by USB peripheral drivers, so this also avoids having to copy data back and forth before and after transfers. The ehci and ohci controllers support scatter/gather as long as the buffer is contiguous in the virtual address space. For uhci the hardware cannot handle a physical address discontinuity within a USB packet, so it is necessary to copy small memory fragments at times. Notes: svn path=/head/; revision=158998

* It was possible to have two threads concurrently aborting the sameIan Dowse2005-03-191-1/+28
| | | | | | | | | | | | | | | | | | | | | transfer, which lead to panics or page faults. For example if a transfer timed out, another thread could come along and attempt to abort the same transfer while the timeout task was sleeping in the *_abort_xfer() function. Add an "aborting" flag to the private transfer state in each host controller driver and use this to ensure that the abort is only executed once. Also prioritise normal abort requests over timeouts so that the callback is always given a status of USB_CANCELLED even if the timeout-initiated abort began first. The crashes caused by this bug were mainly reported in connection with lpd printing to a USB printer. PR: usb/78208, usb/78986 Notes: svn path=/head/; revision=143847

* Attempt to fix a number of race conditions in the handling ofIan Dowse2004-11-091-16/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | transfer timeouts that typically cause a transfer to be completed twice, resulting in panics and page faults: o A transfer completion interrupt could arrive while an abort_task event was set up, so the transfer would be aborted after it had completed. This is very easy to reproduce. Fix this by setting the transfer status to USBD_TIMEOUT before scheduling the abort_task so that the transfer completion code will ignore it. o The transfer completion code could execute concurrently with the timeout callout, leaving the callout blocked (e.g. waiting for Giant) while the transfer completion code runs. In this case, callout_stop() does not prevent the callout from running, so again the timeout code would run after the transfer was complete. Handle this case by checking the return value from callout_stop(), and ignoring the transfer if the callout could not be removed. o Finally, protect against a timeout callout occurring while a transfer is being aborted by another process. Here we arrange for the timeout processing to ignore the transfer, and use callout_drain() to ensure that the callout has really gone before completing the transfer. This was tested by repeatedly performing USB transfers with a timeout set to approximately the same as the normal transfer completion time. In the PR below, apparently this occurred by accident with a particular printer and the default timeout. PR: kern/71491 Notes: svn path=/head/; revision=137475
