2012-11-12USB: report submission of active URBsAlan Stern1-0/+2
This patch (as1633) changes slightly the way usbcore handled submissions of URBs that are already active. It will now return -EBUSY rather than -EINVAL, and it will call WARN_ONCE to draw people's attention to the bug.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next USB gadget patches from Felipe: "usb: gadget: patches for v3.8 renesas_usbhs implements ->pullup() method, switches over to devm_request_irq(), adds support for DMA Engine and got a few miscelaneous cleanups. The NCM gadget got an endianness fix and the Ethernet gadget a frame size fix. We're finally removing the g_file_storage gadget and sticking to g_mass_storage and the new tcm_usb_gadget gadgets since that was a huge duplicaton of effort anyway. While removing g_file_storage, we also had to fix a bunch of defconfigs which were still pointing to the old gadget. There's a big series getting us closer to being able to introduce our configfs interface. The series converts functions into loadable modules which will, eventually, be registered to the configfs interface. Other than that there's the usual typo fixes and miscelaneous cleanups all over the place."

The first 4 bytes are US_BULK_CB_SIGN which is correct. After that we see the TAG which is 0x5e. The cdb is 0x00 in this example. In order to correct this, I change the example to a READ_10 command which is 0x28 so it is not just a zero somewhere in the stream.

2011-08-23usb: Introduce DesignWare USB3 DRD DriverFelipe Balbi1-0/+53
The DesignWare USB3 is a highly configurable IP Core which can be instantiated as Dual-Role Device (DRD), Peripheral Only and Host Only (XHCI) configurations. Several other parameters can be configured like amount of FIFO space, amount of TX and RX endpoints, amount of Host Interrupters, etc. The current driver has been validated with a virtual model of version 1.73a of that core and with an FPGA burned with version 1.83a of the DRD core. We have support for PCIe bus, which is used on FPGA prototyping, and for the OMAP5, more adaptation (or glue) layers can be easily added and the driver is half prepared to handle any possible configuration the HW engineer has chosen considering we have the information on one of the GHWPARAMS registers to do runtime checking of certain features. More runtime checks can, and should, be added in order to make this driver even more flexible with regards to number of endpoints, FIFO sizes, transfer types, etc. While this supports only the device side, for now, we will add support for Host side (xHCI - see the updated series Sebastian has sent [1]) and OTG after we have it all stabilized.

2011-07-09USB: EHCI: Allow users to override 80% max periodic bandwidthKirill Smelkov1-0/+2
There are cases, when 80% max isochronous bandwidth is too limiting. For example I have two USB video capture cards which stream uncompressed video, and to stream full NTSC + PAL videos we'd need NTSC 640x480 YUV422 @30fps ~17.6 MB/s PAL 720x576 YUV422 @25fps ~19.7 MB/s isoc bandwidth. Now, due to limited alt settings in capture devices NTSC one ends up streaming with max_pkt_size=2688 and PAL with max_pkt_size=2892, both with interval=1. In terms of microframe time allocation this gives NTSC ~53us PAL ~57us and together ~110us > 100us == 80% of 125us uframe time. So those two devices can't work together simultaneously because the'd over allocate isochronous bandwidth. 80% seemed a bit arbitrary to me, and I've tried to raise it to 90% and both devices started to work together, so I though sometimes it would be a good idea for users to override hardcoded default of max 80% isoc bandwidth. After all, isn't it a user who should decide how to load the bus? If I can live with 10% or even 5% bulk bandwidth that should be ok. I'm a USB newcomer, but that 80% set in stone by USB 2.0 specification seems to be chosen pretty arbitrary to me, just to serve as a reasonable default. NOTE 1 ~~~~~~ for two streams with max_pkt_size=3072 (worst case) both time allocation would be 60us+60us=120us which is 96% periodic bandwidth leaving 4% for bulk and control. Alan Stern suggested that bulk then would be problematic (less than 300*8 bittimes left per microframe), but I think that is still enough for control traffic. NOTE 2 ~~~~~~ Sarah Sharp expressed concern that maxing out periodic bandwidth could lead to vendor-specific hardware bugs on host controllers, because > It's entirely possible that you'll run into > vendor-specific bugs if you try to pack the schedule with isochronous > transfers. I don't think any hardware designer would seriously test or > validate their hardware with a schedule that is basically a violation of > the USB bus spec (more than 80% for periodic transfers).

NOTE 3 ~~~~~~ This feature is off by default. I mean max periodic bandwidth is set to 100us/uframe by default exactly as it was before the patch. So only those of us who need the extreme settings are taking the risk - normal users who do not alter uframe_periodic_max sysfs attribute should not see any change at all. NOTE 4 ~~~~~~ I've tried to update documentation in Documentation/ABI/ thoroughly, but only "TBD" was put into Documentation/usb/ehci.txt -- the text there seems to be outdated and much needing refreshing, before it could be amended.

2011-06-17USB: Fix up URB error codes to reflect implementation.Sarah Sharp1-1/+8
Documentation/usb/error-codes.txt mentions that urb->status can be set to -EXDEV, if the isochronous transfer was not fully completed. However, in practice, EHCI, UHCI, and OHCI all only set -EXDEV in the individual frame status, never in the URB status. Those host controller actually always pass in a zero status to usb_hcd_giveback_urb, and rely on the core to set the appropriate status value. The xHCI driver ran into issues with the uvcvideo driver when it tried to set -EXDEV in urb->status, because the driver refused to submit URBs, and the userspace camera application's video froze.

This patch (as1459) updates the documentation for the pre_reset method in struct usb_driver. When a driver is notified of an impending reset, it must cancel all outstanding I/O and not start any new I/O until it has been notified that the reset is complete. As far as I know, most existing drivers that implement pre_reset do this now. The major exceptions appear to be the SpeedTouch and CDC-WDM drivers.

This patch (as1428) converts USB over to the new runtime-PM core autosuspend framework.

One expresses the delay time in seconds and the other in milliseconds, but otherwise they do the same thing. The old attribute can be deprecated and then removed eventually.

2010-08-04Documentation: update broken web addresses.Justin P. Mattock3-8/+4
Below you will find an updated version from the original series bunching all patches into one big patch updating broken web addresses that are located in Documentation/* Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult, the best way to deal with these is to use web.archive.org to locate these addresses that are outdated. Now there are also some addresses pointing to .spec files some are located, but some(after searching on the companies site)where still no where to be found. In this case I just changed the address to the company site this way the users can contact the company and they can locate them for the users. Signed-off-by: Justin P.

2010-05-21USB: usbserial: mos7720: add support for parallel port on moschip 7715Mike Dunn1-0/+16
Add support for the parallel port on the moschip MCS7715 device. The port registers itself with the parport subsystem as a low-level driver. A separate entry to the kernel configuration is added beneath that for the mos7720, to avoid the need to link with the parport subsystem code for users who don't have or don't want the parallel port. Only compatibility mode is currently supported (no ECP/EPP). Tested with both moschip devices (7720 and 7715) on UP and SMP hosts, including regression testing of serial port, concurrent operation of serial and parallel ports, and various connect / disconnect scenarios.

For more clearance what the functions actually do, usb_buffer_alloc() is renamed to usb_alloc_coherent() usb_buffer_free() is renamed to usb_free_coherent() They should only be used in code which really needs DMA coherency.

2010-05-21USB: Support for allocating USB 3.0 streams.Sarah Sharp1-0/+78
Bulk endpoint streams were added in the USB 3.0 specification. Streams allow a device driver to overload a bulk endpoint so that multiple transfers can be queued at once. The device then decides which transfer it wants to work on first, and can queue part of a transfer before it switches to a new stream. All this switching is invisible to the device driver, which just gets a completion for the URB. Drivers that use streams must be able to handle URBs completing in a different order than they were submitted to the endpoint. This requires adding new API to set up xHCI data structures to support multiple queues ("stream rings") per endpoint. Drivers will allocate a number of stream IDs before enqueueing URBs to the bulk endpoints of the device, and free the stream IDs in their disconnect function. See Documentation/usb/bulk-streams.txt for details. The new mass storage device class, USB Attached SCSI Protocol (UASP), uses these streams API.

2010-05-21USB: deprecate the power/level sysfs attributeAlan Stern1-8/+11
This patch (as1367) deprecates USB's power/level sysfs attribute in favor of the power/control attribute provided by the runtime PM core. The two attributes do the same thing. It would be nice to replace power/level with a symlink to power/control, but at the moment sysfs doesn't offer any way to do so.
