'make htmldocs' has a fatal error when processing libata.xml, as seen below. The string "Example patterns:" (or any string with "example.*:" in it AFAIK) causes some part of the doc generation tool chain to try to produce an <informalexample> block without a beginning <para>, but there is an ending </para> generated, which throws things out of kilter. I don't even know where (what program) this is happening in. I searched in docproc and xmlto and in some XML stylesheets without finding anything. If anyone can give me pointers about this, please do. Until this is fixed, let's just spell "Example" as "Sample" and match up the double quotation marks while there.

As David VomLehn points out, it was possible to receive an interrupt before clearing the free-urb flag which could lead to the urb being incorrectly marked as busy. For the same reason, move tx_bytes accounting so that it will never be negative. Note that the free-flags set and clear operations do not need any additional locking as they are manipulated while USB_SERIAL_WRITE_BUSY is set.

This patch fixes a race condition in two utility routines related to the removal/unlinking of urbs from an anchor. If two threads are concurrently accessing the same anchor, both could end up with the same urb - thinking they are the exclusive owner. Alan Stern pointed out a related issue in usb_unlink_anchored_urbs: "The URB isn't removed from the anchor until it completes (as a by-product of completion, in fact), which might not be for quite some time after the unlink call returns. In the meantime, the subroutine will keep trying to unlink it, over and over again."

Tell the USB core that we can do DMA directly (instead of needing it to memory-map the buffers for PIO). If the xHCI host supports 64-bit addresses, set the DMA mask accordingly. Otherwise indicate the host can handle 32-bit DMA addresses. This improves performance because the USB core doesn't have to spend time remapping buffers in high memory into the 32-bit address range.

To tell the host controller that there are transfers on the endpoint rings, we need to ring the endpoint doorbell. This is a PCI MMIO write, which can be delayed until another register read is queued. The previous code would flush the doorbell write by reading the doorbell register after the write. This may take time, and it's not necessary to force the host controller to know about the transfers right away. Don't flush the doorbell register writes.

由 Sarah Sharp 提交于
The interrupter register set includes a register that says whether interrupts are pending for each event ring (the IP bit). Each MSI-X vector will get its own interrupter set with separate IP bits. The status register includes an "Event Interrupt (EINT)" bit that is set when an IP bit is set in any of the interrupters. When PCI interrupts are used, the EINT bit exactly mirrors the IP bit in the single interrupter set, and it is a waste of time to check both registers when trying to figure out if the xHC interrupted or another device on the shared IRQ line interrupted. Only check the IP bit to reduce register reads. The IP bit is automatically cleared by the xHC when MSI or MSI-X is enabled. It doesn't make sense to read that register to check for shared interrupts (since MSI and MSI-X aren't shared). It also doesn't make sense to write to that register to clear the IP bit, since it is cleared by the hardware. We can tell whether MSI or MSI-X is enabled by looking at the irq number in hcd->irq. If it's -1, we know MSI or MSI-X is enabled. Signed-off-by: NSarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

The xHCI specification suggests that writing the hardware event ring dequeue pointer register too often can be an expensive operation for the xHCI hardware to manage. It suggests minimizing the number of writes to that register. Originally, the driver wrote the event ring dequeue pointer after each event was processed. Depending on how the event ring moderation register is set up and how fast the transfers are completing, there may be several events processed for each interrupt. This patch makes the hardware event ring dequeue pointer be written only once per interrupt. Make the transfer event handler and port status event handler only write the software event ring dequeue pointer. Move the updating of the hardware event ring dequeue pointer into the interrupt function. Move the contents of xhci_set_hc_event_deq() into the interrupt handler. The interrupt handler must clear the event handler busy flag, so it might as well also write the dequeue pointer to the same register. This eliminates two 32-bit PCI reads and two 32-bit PCI writes.

I've been using perf to measure the top symbols while transferring 1GB of data on a USB 3.0 drive with dd. This is using the raw disk with /dev/sdb, with a block size of 1K. During performance testing, the top symbol was xhci_triad_to_transfer_ring(), a function that should return immediately if streams are not enabled for an endpoint. It turned out that the functions to find the endpoint ring was defined in xhci-mem.c and used in xhci-ring.c and xhci-hcd.c. I moved a copy of xhci_triad_to_transfer_ring() and xhci_urb_to_transfer_ring() into xhci-ring.c and declared them static. I also made a static version of xhci_urb_to_transfer_ring() in xhci.c. This improved throughput on a 1GB read of the raw disk with dd from 186MB/s to 195MB/s, and perf reported sampling the xhci_triad_to_transfer_ring() 0.06% of the time, rather than 9.26% of the time.

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.

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.

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.

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.

Moved the serial parameter handling code out of "#ifdef CONFIG_USB_FILE_STORAGE_TEST". This modifies Yann Cantin's commit "USB: Add a serial number parameter to g_file_storage" module as per Alan Stern's request.
