2014-03-04uas: Urbs must be anchored before submitting themHans de Goede
Otherwise they may complete before they get anchored and thus never get unanchored (as the unanchoring is done by the usb core on completion). This commit also remove the usb_get_urb / usb_put_urb around cmd submission + anchoring, since if done in the proper order this is not necessary.

2014-03-04uas: add dead request listGerd Hoffmann
This patch adds a new list where all requests which are canceled are added to, so we don't loose them. Then, after killing all inflight urbs on bus reset (and disconnect) we'll walk over the list and clean them up. Without this we can end up with aborted requests lingering around in case of status pipe transfer errors.

2014-03-04usbfs: Add support for allocating / freeing streamsHans de Goede
This allows userspace to use bulk-streams, just like in kernel drivers, see Documentation/usb/bulk-streams.txt for details on the in kernel API. This is exported pretty much one on one to userspace. To use streams an app must first make a USBDEVFS_ALLOC_STREAMS ioctl, on success this will return the number of streams available (which may be less then requested). If there are n streams the app can then submit usbdevfs_urb-s with their stream_id member set to 1-n to use a specific stream. IE if USBDEVFS_ALLOC_STREAMS returns 4 then stream_id 1-4 can be used. When the app is done using streams it should call USBDEVFS_FREE_STREAMS Note applications are advised to use libusb rather then using the usbdevfs api directly. The latest version of libusb has support for streams. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>

2014-03-04usbfs: Add support for bulk stream idsHans de Goede
This patch makes it possible to specify a bulk stream id when submitting an urb using the async usbfs API. It overloads the number_of_packets usbdevfs_urb field for this. This is not pretty, but given other constraints it is the best we can do. The reasoning leading to this goes as follows: 1) We want to support bulk streams in the usbfs API 2) We do not want to extend the usbdevfs_urb struct with a new member, as that would mean defining new ioctl numbers for all async API ioctls + adding compat versions for the old ones (times 2 for 32 bit support) 3) 1 + 2 means we need to re-use an existing field 4) number_of_packets is only used for isoc urbs, and streams are bulk only so it is the best (and only) candidate for re-using Note that: 1) This patch only uses number_of_packets as stream_id if the app has actually allocated streams on the ep, so that old apps which may have garbage in there (as it was unused until now in the bulk case), will not break 2) This patch does not add support for allocating / freeing bulk-streams, that is done in a follow up patch Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>

2014-03-04usbfs: Kill urbs on interface before doing a set_interfaceHans de Goede
The usb_set_interface documentation says: * Also, drivers must not change altsettings while urbs are scheduled for * endpoints in that interface; all such urbs must first be completed * (perhaps forced by unlinking). For in kernel drivers we trust the drivers to get this right, but we cannot trust userspace to get this right, so enforce it by killing any urbs still pending on the interface.

2014-03-04xhci: Remove segments from radix tree on failed insert.Sarah Sharp
If we're expanding a stream ring, we want to make sure we can add those ring segments to the radix tree that maps segments to ring pointers. Try the radix tree insert after the new ring segments have been allocated (the last segment in the new ring chunk will point to the first newly allocated segment), but before the new ring segments are linked into the old ring. If insert fails on any one segment, remove each segment from the radix tree, deallocate the new segments, and return. Otherwise, link the new segments into the tree. HdG: Add a check to only update stream mappings in xhci_ring_expansion when the ring is a stream ring.

2014-03-04xhci: For streams the dequeue ptr must be read from the stream ctxHans de Goede
This fixes TR dequeue validation failing on Intel XHCI controllers with the following warning: Mismatch between completed Set TR Deq Ptr command & xHCI internal state. Interestingly enough reading the deq ptr from the ep ctx after a TR Deq Ptr command does work on a Nec XHCI controller, it seems the Nec writes the ptr to both the ep and stream contexts when streams are used.

2014-03-04xhci: Check size rather then number of streams when allocating stream ctxsHans de Goede
Before this a device needing ie 32 stream ctxs would end up with an entry from the small_streams_pool which has 256 bytes entries, where as 32 stream ctxs need 512 bytes.

2014-03-04xhci: Free streams when they are still allocated on a set_interface callHans de Goede
And warn about this, as that would be a driver bug. Like wise drivers should ensure that streams are properly free-ed before a device is reset. So lets warn about that too. This already causes warnings in the form of: [ 96.982398] xhci_hcd 0000:01:00.0: WARN Can't disable streams for endpoint 0x81 , streams are already disabled! [ 96.982400] xhci_hcd 0000:01:00.0: WARN xhci_free_streams() called with non-streams endpoint But it is better to also warn about the actual cause of this later warnings.

2014-03-04xhci: fix usb3 streamsGerd Hoffmann
xhci maintains a radix tree for each stream endpoint because it must be able to map a trb address to the stream ring. Each ring segment must be added to the ring for this to work. Currently xhci sticks only the first segment of each stream ring into the radix tree. Result is that things work initially, but as soon as the first segment is full xhci can't map the trb address from the completion event to the stream ring any more -> BOOM. You'll find this message in the logs: ERROR Transfer event for disabled endpoint or incorrect stream ring This patch adds a helper function to update the radix tree, and a function to remove ring segments from the tree. Both functions loop over the segment list and handles all segments instead of just the first. [Note: Sarah changed this patch to add radix_tree_maybe_preload() and radix_tree_preload_end() calls around the radix tree insert, since we can now insert entries in interrupt context. There are now two helper functions to make the code cleaner, and those functions are moved to make them static.] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>

2014-03-04usb/xhci: Change how we indicate a host supports Link PM.Sarah Sharp
The xHCI driver currently uses a USB core internal field, udev->lpm_capable, to indicate the xHCI driver knows how to calculate the LPM timeout values. If this value is set for the host controller udev, it means Link PM can be enabled for child devices under that host. Change the code so the xHCI driver isn't mucking with USB core internal fields. Instead, indicate the xHCI driver doesn't support Link PM on this host by clearing the U1 and U2 exit latencies in the roothub SuperSpeed Extended Capabilities BOS descriptor. The code to check for the roothub setting U1 and U2 exit latencies to zero will also disable LPM for external devices that do that same. This was already effectively done with commit ae8963adb4ad8c5f2a89ca1d99fb7bb721e7599f "usb: Don't enable LPM if the exit latency is zero." Leave that code in place, so that if a device sets one exit latency value to zero, but the other is set to a valid value, LPM is only enabled for the U1 or U2 state that had the valid value. This is the same behavior the code had before. Also, change messages about missing Link PM information from warning level to info level. Only print a warning about the first device that doesn't support LPM, to avoid log spam. Further, cleanup some unnecessary line breaks to help people to grep for the error messages.
