* USB: serial: enabling support for Segway RMP in ftdi_sioJohn G. Rogers2010-08-102-0/+6
| | | | | | | | | | | | | | | | I have added the ProductID=0xe729 VendorID=FTDI_VID=0x0403 which will enable support for the Segway Robotic Mobility Platform (RMP200) in the ftdi_sio kernel module. Currently, users of the Segway RMP200 must use a RUN+="/sbin/modprobe -q ftdi-sio product=0xe729 vendor=0x0403 in a udev rule to get the ftdi_sio module to handle the usb interface and mount it on /dev/ttyXXX. This is not a good solution because some users will have multiple USB to Serial converters which will use the ftdi_sio module.

* USB: s3c-hsotg: Add initial detection and setup for dedicated FIFO modeBen Dooks2010-08-102-2/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the dedicated FIFO mode on newer SoCs such as the S5PV210 partly to improve support and to fix the bug where any non-EP0 IN endpoint requires its own FIFO allocation. To fix this, we ensure that any non-zero IN endpoint is given a TXFIFO using the same allocation method as the periodic case (all our current hardware has enough FIFOs and FIFO memory for a 1:1 mapping) and ensure that the necessary transmission done interrupt is enabled. The default settings from reset for the core point all EPs at FIFO0, used for the control endpoint. However, the controller documentation states that all IN endpoints _must_ have a unique FIFO to avoid any contention during transmission. Note, this leaves us with a large IN FIFO for EP0 (which re-uses the old NPTXFIFO) for an endpoint which cannot shift more than a pair of packets at a time... this is a waste, but it looks like we cannot re-allocate space to the individual IN FIFOs as they are already maxed out (to be confirmed).

| | | | | | | | | | | | | | In shared fifo mode (used on older SoCs) the periodic in fifo beahves much more like a packet buffer, discarding old data when writing new data. Avoid this by ensuring that we do not load new transactions in when there is data sitting already in the FIFO. Note, this may not be an observed bug, we are fixing the case that this may happen.

| | | | | | | | | | | | | | | Fix a problem where we have been underestimating the space available in the IN PTX/NPTX FIFOs by assuming that they where simply word aligned instead of in number-of-words. This means all length calculations need to be multiplied-by-4. Note, we do not change the information about fifo size or start addresses available to userspace as we assume the user can multiply by four easily and is already knows these values are in words.

* USB: s3c-hsotg: Increase TX fifo limitBen Dooks2010-08-101-2/+2
| | | | | | | | | | | | | | | | | | | | Up the FIFO size for the TX to 1024 entries, as this now seems to work with all the cores. This fixes a problem when using large packets on a core with MPS set to 512 can hang due to insufficient space for the writes. The hang arises due to getting the non-periodic FIFO empty IRQ but not being able to satisfy any requests since there is never enough space to write 512 bytes into the buffer. This means we end up with a stream of interrupt requests. It is easier to up the TX FIFO to fill the space we left for it than to try and fix the positions in the code where we should have limited the max-packet size to < TXFIFOSIZE, since the TXFIFOSIZE depends on how the TX FIFOs have been setup.

| | | | | | | | | | | | | | | | | | | | | | | | | MS Windows mounts removable storage in "Removal optimized mode" by default. All the writes to the media are synchronous which is achieved by setting FUA (Force Unit Access) bit in SCSI WRITE(10,12) commands.

| | | | | | | | | | | | | | | | Isochronous endpoint needs a bigger size of transfer ring. Isochronous URB consists of multiple packets, each packet needs a isoc td to carry, and there will be multiple trbs inserted to the ring at one time. One segment is too small for isochronous endpoints, and it will result in room_on_ring() check failure and the URB is failed to enqueue. Allocate bigger ring for isochronous endpoint. 8 segments should be enough. This will be replaced with dynamic ring expansion in the future.

* USB: xHCI: Isochronous transfer implementationAndiry Xu2010-08-102-0/+324
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements isochronous urb enqueue and interrupt handler part. When an isochronous urb is passed to xHCI driver, first check the transfer ring to guarantee there is enough room for the whole urb. Then update the start_frame and interval field of the urb. Always assume URB_ISO_ASAP is set, and never use urb->start_frame as input. The number of isoc TDs is equal to urb->number_of_packets. One isoc TD is consumed every Interval. Each isoc TD consists of an Isoch TRB chained to zero or more Normal TRBs. Call prepare_transfer for each TD to do initialization; then calculate the number of TRBs needed for each TD. If the data required by an isoc TD is physically contiguous (not crosses a page boundary), then only one isoc TRB is needed; otherwise one or more additional normal TRB shall be chained to the isoc TRB by the host. Set TRB_IOC to the last TRB of each isoc TD. Do not ring endpoint doorbell to start xHC procession until all the TDs are inserted to the endpoint transer ring. In irq handler, update urb status and actual_length, increase urb_priv->td_cnt. When all the TDs are completed(td_cnt is equal to urb_priv->length), giveback the urb to usbcore.

* USB: xHCI: Introduce urb_priv structureAndiry Xu2010-08-104-34/+125
| | | | | | | | | | | | | | | | | | | | | | | Add urb_priv data structure to xHCI driver. This structure allows multiple xhci TDs to be linked to one urb, which is essential for isochronous transfer. For non-isochronous urb, only one TD is needed for one urb; for isochronous urb, the TD number for the urb is equal to urb->number_of_packets. The length field of urb_priv indicates the number of TDs in the urb. The td_cnt field indicates the number of TDs already processed by xHC. When td_cnt matches length, the urb can be given back to usbcore. When an urb is dequeued or cancelled, add all the unprocessed TDs to the endpoint's cancelled_td_list. When process a cancelled TD, increase td_cnt field. When td_cnt equals urb_priv->length, giveback the cancelled urb.

| | | | | | | | | | | | | | This patch adds mechanism to process Missed Service Error Event. Sometimes the xHC is unable to process the isoc TDs in time, it will generate Missed Service Error Event.

* USB: EHCI: reorganize isochronous scheduler routineAlan Stern2010-08-101-53/+57
| | | | | | | | | | | | | | | | | | | | | | | | This patch (as1408) rearranges the scheduling code in ehci-hcd, partly to improve its structure, but mainly to change the way it works. Whether or not a transfer exceeds the hardware schedule length will now be determined by looking at the last frame the transfer would use, instead of the first available frame following the end of the transfer. The benefit of this change is that it allows the driver to accept valid URBs which would otherwise be rejected. For example, suppose the schedule length is 1024 frames, the endpoint period is 256 frames, and a four-packet URB is submitted. The four transfers would occupy slots that are 0, 256, 512, and 768 frames past the current frame (plus an extra slop factor). These don't exceed the 1024-frame limit, so the URB should be accepted. But the current code notices that the next available slot would be 1024 frames (plus slop) in the future, which is beyond the limit, and so the URB is rejected unnecessarily.

* USB: EHCI: add missing frame -> microframe conversionAlan Stern2010-08-102-10/+19
| | | | | | | | | | | | | | | | | | | | This patch (as1407) fixes a bug in ehci-hcd's isochronous scheduler. All its calculations should be done in terms of microframes, but for full-speed devices, sched->span is stored in frames. It needs to be converted. This fix is liable to expose problems in other drivers. The old code would accept URBs that should not have been accepted, so drivers have had no reason to avoid submitting URBs that exceeded the maximum schedule length. In an attempt to partially compensate for this, the patch also adjusts the schedule length from a minimum of 256 frames up to a minimum of 512 frames.

* USB: EHCI Debug Port Device Gadgetstephane duverger2010-08-103-0/+464
| | | | | | | | | | | | | | | | | | | | This is a patch that implements an USB EHCI Debug Device using the Gadget API. This patch applies to a 2.6.35-rc3 kernel. The gadget needs a compliant usb controller that forwards the USB_DEVICE_DEBUG_MODE feature to its gadget. The gadget provides two configuration modes, one that only printk() the received data, and one that exposes a serial device to userland (/dev/ttyGSxxx). The gadget has been tested on an IGEPv2 board running a 2.6.35-rc1 kernel. The debug port was fed on the host side by a 2.6.34 kernel.
