This patch (as1400) adds runtime-PM support to usb-storage. It utilizes the SCSI layer's runtime-PM implementation, so its scope is limited. Currently the only effect is that disk-like devices (such as card readers or flash drives) will be autosuspended if they aren't mounted and their device files aren't open. This would apply, for example, to card readers that don't contain a memory card. Unfortunately this won't interact very well with the removable-media polling normally carried out by hal or DeviceKit. Maybe those programs can be changed to use a longer polling interval, or maybe the default autosuspend time for usb-storage should be set to something below 1 second. Signed-off-by:

The patch below on gregkh tree only creates 'lpm' file under ehci->debug_dir, but not removes it when unloading module, USB: EHCI: EHCI 1.1 addendum: preparation which can make loading of ehci-hcd module failed after unloading it. This patch replaces debugfs_remove with debugfs_remove_recursive to remove ehci debugfs dir and files. It does fix the bug above, and may simplify the removing procedure. Also, remove the debug_registers, debug_async and debug_periodic field from ehci_hcd struct since they are useless now. Signed-off-by:

This patch is to add a US Interface, Inc. "Navigator" USB device. Specifically, it's a HAM Radio USB sound modem that also incorporates three pairs of unique FTDI serial ports. The standard Linux FTDI serial driver will only recognize the first two serial ports of an unknown FDTI derived device and this patch adds in recognition to these specific new IDs. Signed-off-by:

This patch (as1410) makes a slight change to the strategy used for choosing a default configuration. Currently we skip configs whose first interface is RNDIS, if the kernel wasn't built with the corresponding driver. This risks losing access to the other interfaces in those configs. In addition, if there is only one config then we will end up not configuring the device at all. This changes the logic; now such configurations will be skipped only if there is at least one other config. Signed-off-by:

This patch adds the product IDs of Huawei's K3765 and K4505 mobile broadband usb modems to option.c. It also adds a quirk to the option probe function so that binding to the device's network interface(class 0xff) is avoided. This is necessary to allow another driver to bind to that, and to avoid programs like wvdial opening a nonfunctioning tty during modem discovery. Signed-off-by:

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. Signed-off-by:

If there is more data in the request than we could fit into a single hardware request, then check when the OutDone event is received if we have more data, and if so, schedule the new data instead of trying to complete the request (and in the case of EP0, sending a 0 packet in the middle of a transfer). Also, move the debug message about the current transfer state before the warning about a bad transfer. Signed-off-by:

Before trying a new setup transaction after getting an EP0 in complete interrupt, check that the driver did not try and send more EP0 IN data before enqueing a new setup transaction. This fixes a bug where we cannot send all of the IN data in one go so split the transfer, but then fail to send all the data as we start waiting for a new OUT transaction Signed-off-by:

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).

The USB documentation suggest that the FIFOs should be reset when a bus reset event happens. Use the s3c_hsotg_init_fifo() to ensure that the FIFO layout is correct and that the FIFOs are flushed before acknowledging the reset. Signed-off-by:

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.

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. This prevents I/O requests aggregation in block layer dramatically decreasing performance. This patch brings an option to accept or ignore mentioned bit a) via specifying module parameter "nofua", or b) through sysfs entry /sys/devices/platform/_UDC_/gadget/gadget-lunX/nofua (_UDC_ is the name of the USB Device Controller driver) Patch is based on the work that was done by Denis Karpov for Maemo 5 platform.

Bring a strict way to get the 'ro' parameter from the user. The patch followed by this one adds another boolean parameter. To be consistent Michał Nazarewicz proposed to use simple_strtol() in both cases (correspondend discussion in LKML [1]). Due to simple_strtol() doesn't return error in a good way and we have a boolean parameter the strict_strtoul() is used. [1] http://lkml.org/lkml/2010/7/14/169Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. In this case some TDs on the ring are not processed and missed. When encounter a Missed Servce Error Event, set the skip flag of the ep, and process the missed TDs until reach the next processed TD, then clear the skip flag. Signed-off-by:
