Contrary to what the comment says, setting\nthe Halt bit does not cause the QH to be patched later; that decision\n(made in qh_refresh()) depends only on whether the QH is currently\npointing to a valid qTD. Likewise, setting the Halt bit does not\nprevent completions from activating the QH while it is \"stopped\"; they\nare prevented by the fact that qh_completions() temporarily changes\nqh-\u003eqh_state to QH_STATE_COMPLETING.\n\nOn the other hand, there are circumstances in which the QH will be\nreactivated _without_ being patched; this happens after an URB beyond\nthe head of the queue is unlinked. Setting the Halt bit will then\ncause the hardware to see the QH with both the Active and Halt bits\nset, an invalid combination that will prevent the queue from\nadvancing and may even crash some controllers.\n\nApparently the only reason this hasn\u0027t been reported before is that\nunlinking URBs from the middle of a running queue is quite uncommon.\nHowever Test 17, recently added to the usbtest driver, does exactly\nthis, and it confirms the presence of the bug.\n\nIn short, there is no reason to set the Halt bit for an unlinked or\nblocked QH, and there is a very good reason not to set it.

To do that, the driver issues\na Set TR Dequeue Pointer command, which will complete some time later.\n\nTakashi was having issues with USB 1.1 audio devices that stalled, and his\nanalysis of the code was that the old code would not update the xHCI\ndriver\u0027s ring dequeue pointer after the command completes. However, the\ndequeue pointer is set in xhci_find_new_dequeue_state(), just before the\nset command is issued to the hardware.\n\nSetting the dequeue pointer before the Set TR Dequeue Pointer command\ncompletes is a dangerous thing to do, since the xHCI hardware can fail the\ncommand. Instead, store the new dequeue pointer in the xhci_virt_ep\nstructure, and update the ring\u0027s dequeue pointer when the Set TR dequeue\npointer command completes.\n\nWhile we\u0027re at it, make sure we can\u0027t queue another Set TR Dequeue Command\nwhile the first one is still being processed. This just won\u0027t work with\nthe internal xHCI state code.

This touches\nthe driver initialization and shutdown paths, roothub emulation code, and\nport status change event handlers. This is a rather large patch, but it\ncan\u0027t be broken up, or it would break git-bisect.\n\nMake the xHCI driver register its own PCI probe function. This will call\nthe USB core to create the USB 2.0 roothub, and then create the USB 3.0\nroothub. This gets the code for registering a shared roothub out of the\nUSB core, and allows other HCDs later to decide if and how many shared\nroothubs they want to allocate.\n\nMake sure the xHCI\u0027s reset method marks the xHCI host controller\u0027s primary\nroothub as the USB 2.0 roothub. This ensures that the high speed bus will\nbe processed first when the PCI device is resumed, and any USB 3.0 devices\nthat have migrated over to high speed will migrate back after being reset.\nThis ensures that USB persist works with these odd devices.\n\nThe reset method will also mark the xHCI USB2 roothub as having an\nintegrated TT. Like EHCI host controllers with a \"rate matching hub\" the\nxHCI USB 2.0 roothub doesn\u0027t have an OHCI or UHCI companion controller.\nIt doesn\u0027t really have a TT, but we\u0027ll lie and say it has an integrated\nTT. We need to do this because the USB core will reject LS/FS devices\nunder a HS hub without a TT.\n\nOther details:\n-------------\n\nThe roothub emulation code is changed to return the correct number of\nports for the two roothubs. For the USB 3.0 roothub, it only reports the\nUSB 3.0 ports. For the USB 2.0 roothub, it reports all the LS/FS/HS\nports. The code to disable a port now checks the speed of the roothub,\nand refuses to disable SuperSpeed ports under the USB 3.0 roothub.\n\nThe code for initializing a new device context must be changed to set the\nproper roothub port number. Since we\u0027ve split the xHCI host into two\nroothubs, we can\u0027t just use the port number in the ancestor hub. Instead,\nwe loop through the array of hardware port status register speeds and find\nthe Nth port with a similar speed.\n\nThe port status change event handler is updated to figure out whether the\nport that reported the change is a USB 3.0 port, or a non-SuperSpeed port.\nOnce it figures out the port speed, it kicks the proper roothub.\n\nThe function to find a slot ID based on the port index is updated to take\ninto account that the two roothubs will have over-lapping port indexes.\nIt checks that the virtual device with a matching port index is the same\nspeed as the passed in roothub.\n\nThere\u0027s also changes to the driver initialization and shutdown paths:\n\n 1. Make sure that the xhci_hcd pointer is shared across the two\n usb_hcd structures. The xhci_hcd pointer is allocated and the\n registers are mapped in when xhci_pci_setup() is called with the\n primary HCD. When xhci_pci_setup() is called with the non-primary\n HCD, the xhci_hcd pointer is stored.\n\n 2. Make sure to set the sg_tablesize for both usb_hcd structures. Set\n the PCI DMA mask for the non-primary HCD to allow for 64-bit or 32-bit\n DMA. (The PCI DMA mask is set from the primary HCD further down in\n the xhci_pci_setup() function.)\n\n 3. Ensure that the host controller doesn\u0027t start kicking khubd in\n response to port status changes before both usb_hcd structures are\n registered. xhci_run() only starts the xHC running once it has been\n called with the non-primary roothub. Similarly, the xhci_stop()\n function only halts the host controller when it is called with the\n non-primary HCD. Then on the second call, it resets and cleans up the\n MSI-X irqs.\n\nSigned-off-by: Sarah Sharp \u003csarah.a.sharp@linux.intel.com\u003e\n" }, { "commit": "5233630fcdd6f7d415dcbed264031439cab73f9d", "tree": "f877073953835d8989c83ab8473cf2100b64dd84", "parents": [ "20b67cf51fa606442bb343afad0ee1a393a6afb3" ], "author": { "name": "Sarah Sharp", "email": "sarah.a.sharp@linux.intel.com", "time": "Thu Dec 16 10:49:09 2010 -0800" }, "committer": { "name": "Sarah Sharp", "email": "sarah.a.sharp@linux.intel.com", "time": "Sun Mar 13 18:23:38 2011 -0700" }, "message": "xhci: Change xhci_find_slot_id_by_port() API.\n\nxhci_find_slot_id_by_port() tries to map the port index to the slot ID for\nthe USB device.

If an isochronous device is connected to OHCI/EHCI/xHCI port and is active;\n2. Optional PM feature that powers down the internal Bus PLL when the link is\n in low power state is enabled.\n\nWithout AMD PLL quirk, USB isochronous stream may stutter or have breaks\noccasionally, which greatly impair the performance of audio/video streams.\n\nCurrently AMD PLL quirk is implemented in OHCI and EHCI driver, and will be\nadded to xHCI driver too. They are doing similar things actually, so move\nthe quirk code to pci-quirks.c, which has several advantages:\n\n1. Remove duplicate defines and functions in OHCI/EHCI (and xHCI) driver and\n make them cleaner;\n2. AMD chipset information will be probed only once and then stored.\n Currently they\u0027re probed during every OHCI/EHCI initialization, move\n the detect code to pci-quirks.c saves the repeat detect cost;\n3.

This may\n| be observed sometimes with USB-to-serial or USB-to-network devices.\n| The problem is not noticed when only USB mass storage devices are running.\n|2.2 Implication\n| This issue is because of the clearing of the respective Done Map bit on reading the ATL\n| PTD Done Map register when an INT is generated by another PTD completion, but is not\n| found set on that read access. In this situation, the respective Done Map bit will remain\n| reset and no further INT will be asserted so the data transfer corresponding to that USB\n| device will stop.\n|2.3 Workaround\n| An SOF INT can be used instead of an ATL INT with polling on Done bits. A time-out can\n| be implemented and if a certain Done bit is never set, verification of the PTD completion\n| can be done by reading PTD contents (valid bit).\n| This is a proven workaround implemented in software.\n\nRussell King run into this with an USB-to-serial converter.
