2013-10-12USB: EHCI: use consistent NO_FRAME valueAlan Stern2-6/+7
ehci-hcd is inconsistent in the sentinel values it uses to indicate that no frame number has been assigned for a periodic transfer. Some places it uses NO_FRAME (defined as 65535), other places it uses -1, and elsewhere it uses 9999. This patch defines a value for NO_FRAME which can fit in a 16-bit signed integer, and changes the code to use it everywhere.

2013-10-12USB: EHCI: change toggle only upon successful resetAlan Stern1-1/+1
ehci-hcd uses a value of 0 in an endpoint's toggle flag to indicate that the endpoint has been reset (and therefore the Data Toggle bit needs to be cleared in the endpoint's QH overlay region). The toggle flag should be set to 0 only when ehci_endpoint_reset() succeeds. This patch moves the usb_settoggle() call into the appropriate branch of the "if" statement.

2013-10-12USB: EHCI: No SSPLIT allowed in uframe 7Alan Stern1-0/+4
The scheduling code in ehci-hcd contains an error. For full-speed isochronous-OUT transfers, the EHCI spec forbids scheduling Start-Split transactions in H-microframe 7, but the driver allows it anyway. This patch adds a check to prevent it.

2013-10-12USB: EHCI: compute full-speed bandwidth usage correctlyAlan Stern1-1/+1
Although the bandwidth statistics maintained by ehci-hcd show up only in the /sys/kernel/debug/usb/devices file, they ought to be calculated correctly. The calculation for full-speed isochronous endpoints is wrong; it mistakenly yields bytes per microframe instead of bytes per frame. The "interval" value, which is in frames, should not be converted to microframes. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-10-12USB: EHCI: check the right uframes for CSPLITAlan Stern1-1/+1
The check_intr_schedule() routine in ehci-hcd looks at the wrong microframes when checking to see if a full-speed or low-speed interrupt endpoint will fit in the periodic schedule. If the Start-Split transaction is scheduled for microframe N then the Complete-Split transactions get scheduled for microframes N+2, N+3, and N+4. However the code considers N+1, N+2, and N+3 instead. This patch fixes the limits on the "for" loop and also improves the use of whitespace.

2013-10-12USB: NS_TO_US should round upAlan Stern1-3/+2
Host controller drivers use the NS_TO_US macro to convert transaction times, which are computed in nanoseconds, to microseconds for scheduling. Periodic scheduling requires worst-case estimates, but the macro does its conversion using round-to-nearest. This patch changes it to use round-up, giving a correct worst-case value.

2013-10-12usb-anchor: Delay usb_wait_anchor_empty_timeout wake up till completion is doneHans de Goede3-2/+48
usb_wait_anchor_empty_timeout() should wait till the completion handler has run. Both the zd1211rw driver and the uas driver (in its task mgmt) depend on the completion handler having completed when usb_wait_anchor_empty_timeout() returns, as they read state set by the completion handler after an usb_wait_anchor_empty_timeout() call. But __usb_hcd_giveback_urb() calls usb_unanchor_urb before calling the completion handler. This is necessary as the completion handler may re-submit and re-anchor the urb. But this introduces a race where the state these drivers want to read has not been set yet by the completion handler (this race is easily triggered with the uas task mgmt code). I've considered adding an anchor_count to struct urb, which would be incremented on anchor and decremented on unanchor, and then only actually do the anchor / unanchor on 0 -> 1 and 1 -> 0 transtions, combined with moving the unanchor call in hcd_giveback_urb to after calling the completion handler. But this will only work if urb's are only re-anchored to the same anchor as they were anchored to before the completion handler ran. And at least one driver re-anchors to another anchor from the completion handler (rtlwifi). So I have come up with this patch instead, which adds the ability to suspend wakeups of usb_wait_anchor_empty_timeout() waiters to the usb_anchor functionality, and uses this in __usb_hcd_giveback_urb() to delay wake-ups until the completion handler has run.

2013-10-06usb: wusbcore: add support for isoc out transfersThomas Pugliese2-102/+406
This patch adds support for isochronous out transfers to the HWA. The primary changes are: 1. Add a isoc_pack_desc_urb field to struct wa_seg. This urb is used to send the isochronous packet info message to the HWA which describes the isoc data segment(s) that will be sent as the payload of the transfer request. 2. Use the URB iso_frame_desc field to populate the isochronous packet info message and data segments sent to the HWA. 3. After the data is sent and transfer result is returned from the HWA, read the isoc packet status message from the HWA. The contents of the isoc packet status message are used to set the iso_frame_desc status and actual_length fields in the original isoc URB. This feature required the addition of a some state tracking variables in struct wahc so the dti_urb knows what type of packet it expects to receive next.
