Start of frames may or may not\nalso disappear, causing the device to go into auto-suspend. This \"bus\nstall\" will continue until a control or bulk transfer is queued to a\ndevice under that roothub.\n\nMost drivers will never cause this behavior, because they use multiple\nURBs with multiple packets to keep the bus busy. If you limit the number\nof URBs to one, you may be able to hit this bug.\n\nMake sure the EHCI driver does not schedule full-speed transfers within\nthe IST under an Intel chipset.

We can\u0027t modify the\nbuffer pointers on endpoint rings without issuing and waiting for a stop\nendpoint command. Since URBs can be canceled in interrupt context, we\ncan\u0027t wait on that command. The old code trusted that the host\ncontroller would respond to the command, and would giveback the URBs in\nthe event handler. If the hardware never responds to the stop endpoint\ncommand, the URBs will never be completed, and we might hang the USB\nsubsystem.\n\nImplement a watchdog timer that is spawned whenever a stop endpoint\ncommand is queued. If a stop endpoint command event is found on the\nevent ring during an interrupt, we need to stop the watchdog timer with\ndel_timer(). Since del_timer() can fail if the timer is running and\nwaiting on the xHCI lock, we need a way to signal to the timer that\neverything is fine and it should exit. If we simply clear\nEP_HALT_PENDING, a new stop endpoint command could sneak in and set it\nbefore the watchdog timer can grab the lock.\n\nInstead we use a combination of the EP_HALT_PENDING flag and a counter\nfor the number of pending stop endpoint commands\n(xhci_virt_ep-\u003estop_cmds_pending). If we need to cancel the watchdog\ntimer and del_timer() succeeds, we decrement the number of pending stop\nendpoint commands. If del_timer() fails, we leave the number of pending\nstop endpoint commands alone. In either case, we clear the\nEP_HALT_PENDING flag.\n\nThe timer will decrement the number of pending stop endpoint commands\nonce it obtains the lock. If the timer is the tail end of the last stop\nendpoint command (xhci_virt_ep-\u003estop_cmds_pending \u003d\u003d 0), and the\nendpoint\u0027s command is still pending (EP_HALT_PENDING is set), we assume\nthe host is dying. The watchdog timer will set XHCI_STATE_DYING, try to\nhalt the xHCI host, and give back all pending URBs.\n\nVarious other places in the driver need to check whether the xHCI host\nis dying. If the interrupt handler ever notices, it should immediately\nstop processing events. The URB enqueue function should also return\n-ESHUTDOWN. The URB dequeue function should simply return the value\nof usb_hcd_check_unlink_urb() and the watchdog timer will take care of\ngiving the URB back. When a device is disconnected, the xHCI hardware\nstructures should be freed without issuing a disable slot command (since\nthe hardware probably won\u0027t respond to it anyway). The debugging\npolling loop should stop polling if the host is dying.\n\nWhen a device is disconnected, any pending watchdog timers are killed\nwith del_timer_sync(). It must be synchronous so that the watchdog\ntimer doesn\u0027t attempt to access the freed endpoint structures.\n\nSigned-off-by: Sarah Sharp \u003csarah.a.sharp@linux.intel.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "4f0f0baef017dfd5d62b749716ab980a825e1071", "tree": "74f84a4ddd6ea41c5d359a4ecf1f25fa0a2c7d4d", "parents": [ "678539cfaa090093a9aef185f545f6b17acc445c" ], "author": { "name": "Sarah Sharp", "email": "sarah.a.sharp@linux.intel.com", "time": "Tue Oct 27 10:56:33 2009 -0700" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Fri Dec 11 11:55:17 2009 -0800" }, "message": "USB: xhci: Re-purpose xhci_quiesce().\n\nxhci_quiesce() is basically a no-op right now.

When the stop endpoint command is\nhandled by the event handler, the endpoint ring is assumed to be stopped.\nWhen a stop endpoint command is queued, URB submissions are to not ring\nthe doorbell. The old code would check the number of pending URBs to be\ncanceled, and would not ring the doorbell if it was non-zero.\n\nHowever, the following race condition could occur with the old code:\n\n1. Cancel an URB, add it to the list of URBs to be canceled, queue the stop\n endpoint command, and increment ep-\u003ecancels_pending to 1.\n2. The URB finishes on the HW, and an event is enqueued to the event ring\n (at the same time as 1).\n3. The stop endpoint command finishes, and the endpoint is halted. An\n event is queued to the event ring.\n4. The event handler sees the finished URB, notices it was to be\n canceled, decrements ep-\u003ecancels_pending to 0, and removes it from the to\n be canceled list.\n5. The event handler drops the lock and gives back the URB. The\n completion handler requeues the URB (or a different driver enqueues a new\n URB). This causes the endpoint\u0027s doorbell to be rung, since\n ep-\u003ecancels_pending \u003d\u003d 0. The endpoint is now running.\n6. A second URB is canceled, and it\u0027s added to the canceled list.\n Since ep-\u003ecancels_pending \u003d\u003d 0, a new stop endpoint command is queued, and\n ep-\u003ecancels_pending is incremented to 1.\n7. The event handler then sees the completed stop endpoint command. The\n handler assumes the endpoint is stopped, but it isn\u0027t. It attempts to\n move the dequeue pointer or change TDs to cancel the second URB, while the\n hardware is actively accessing the endpoint ring.\n\nTo eliminate this race condition, a new endpoint state bit is introduced,\nEP_HALT_PENDING. When this bit is set, a stop endpoint command has been\nqueued, and the command handler has not begun to process the URB\ncancellation list yet. The endpoint doorbell should not be rung when this\nis set. Set this when a stop endpoint command is queued, clear it when\nthe handler for that command runs, and check if it\u0027s set before ringing a\ndoorbell. ep-\u003ecancels_pending is eliminated, because it is no longer\nused.\n\nMake sure to ring the doorbell for an endpoint when the stop endpoint\ncommand handler runs, even if the canceled URB list is empty. All\ncanceled URBs could have completed and new URBs could have been enqueued\nwithout the doorbell being rung before the command was handled.\n\nSigned-off-by: Sarah Sharp \u003csarah.a.sharp@linux.intel.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "54ab2b02ef6a454b4cca969f546d0dd43fec7308", "tree": "f2fe9420e0da8dc30d350f04c1ab55c0a8e96cd5", "parents": [ "2d57a95f09cf71c4c642e5be15f8b700d17ee90c" ], "author": { "name": "Felipe Balbi", "email": "felipe.balbi@nokia.com", "time": "Wed Oct 14 11:44:14 2009 +0300" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Fri Dec 11 11:55:16 2009 -0800" }, "message": "USB: host: ehci: introduce omap ehci-hcd driver\n\nthis driver has been sitting in linux-omap tree for quite\nsome time.

In theory a STALL indicates either that the\ndownstream device sent a STALL or that no matching TT buffer could be\nfound. In either case, the transfer is completed and the TT buffer\ndoes not remain busy, so it doesn\u0027t need to be cleared.\n\nAlso, the patch fixes a minor flaw in the code that actually sends the\nClear-TT-Buffer requests.

If the QH isn\u0027t idle then an unlink\ncycle will be initiated, and the proper action will be taken when it\nbecomes idle.\n\nAlso, an unnecessary test is removed from qh_link_async(): That\nroutine is never called if the QH\u0027s state isn\u0027t IDLE.\n\nSigned-off-by: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nCC: David Brownell \u003cdavid-b@pacbell.net\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "74aee796c613f54e9f089170df548c0b3f15af69", "tree": "90e63e4648aa228a51993650d48c997feae77d9c", "parents": [ "63ead6a00d54a645667c141d8aaf0f6ffe1212be" ], "author": { "name": "H Hartley Sweeten", "email": "hartleys@visionengravers.com", "time": "Thu Aug 13 13:18:02 2009 -0400" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Wed Sep 23 06:46:34 2009 -0700" }, "message": "USB: ohci-ep93xx.c: remove unused variable\n\nRemove unused variable in ohci-ep93xx.c.\n\nThis only shows up when CONFIG_PM is enabled.\n\nSigned-off-by: H Hartley Sweeten \u003chsweeten@visionengravers.com\u003e\nCc: Lennert Buytenhek \u003ckernel@wantstofly.org\u003e\nCc: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "3d2b0814f15f94506156943c8148da90b6491453", "tree": "65b44d1dfcfd0daa495f6c8998737a522f150605", "parents": [ "015798b2f166725b1dae2b07b5ffb127ab187be0" ], "author": { "name": "Julia Lawall", "email": "julia@diku.dk", "time": "Wed Aug 12 16:51:09 2009 +0200" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Wed Sep 23 06:46:33 2009 -0700" }, "message": "USB: isp1362: Correct use of ! and \u0026\n\nCorrect priority problem in the use of ! and \u0026.\n\nThe semantic patch that makes this change is as follows:\n(http://www.emn.fr/x-info/coccinelle/)\n\n// \u003csmpl\u003e\n@@ expression E; constant C; @@\n- !E \u0026 C\n+ !(E \u0026 C)\n// \u003c/smpl\u003e\n\nSigned-off-by: Julia Lawall \u003cjulia@diku.dk\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "015798b2f166725b1dae2b07b5ffb127ab187be0", "tree": "8e737d2a85ba93bbe135051c426993f9cc272f2a", "parents": [ "0ffd3b2902e28b13d8379df0f09a55668f330f77" ], "author": { "name": "Jon Hunter", "email": "jon-hunter@ti.com", "time": "Wed Aug 12 11:57:59 2009 -0400" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Wed Sep 23 06:46:33 2009 -0700" }, "message": "USB: EHCI: ensure all watchdog timer events are deleted when suspending usb\n\nThis patch was previously discussed in the following thread:\nhttp://thread.gmane.org/gmane.linux.usb.general/19472/focus\u003d19484\n\nOn the OMAP3 device the usbhost controller is in a separate internal\npower-domain.

And of course they don\u0027t do _any_ QA, since that would\ntake too much time away from their crack-smoking habit.\n\nThe real fix, of course, is for consumers to refuse to buy motherboards\nwhich only have closed-source firmware available.
