linux-toradex.git/drivers/usb, branch v2.6.23.12 Linux kernel for Apalis and Colibri modules USB: fix up EHCI startup synchronization 2007-12-14T17:50:53+00:00 David Brownell david-b@pacbell.net 2007-11-28T22:50:03+00:00 d57b4ae3d48871e50eef320a12bd3698a67f4eed patch 1cb52658b4f5b10a9e91f8e1c21ca2bcc1b9a3ca in mainline. A recent patch added software synchronization during EHCI startup, so ports aren't switched away from the companion controllers after resets have started. This patch adds a short delay letting hardware finish that port switching before any new resets begin ... so both ends of that hardware race window are closed.

USB: mutual exclusion for EHCI init and port resets 2007-11-16T17:30:22+00:00 Alan Stern stern@rowland.harvard.edu 2007-10-12T22:19:14+00:00 34f84ffa2b3fa5af7e2cd27d0569ded38786396a patch 32fe01985aa2cb2562f6fc171e526e279abe10db in mainline. This patch (as999) fixes a problem that sometimes shows up when host controller driver modules are loaded in the wrong order. If ehci-hcd happens to initialize an EHCI controller while the companion OHCI or UHCI controller is in the middle of a port reset, the reset can fail and the companion may get very confused. The patch adds an rw-semaphore and uses it to keep EHCI initialization and port resets mutually exclusive.

usb-gadget-ether: prevent oops caused by error interrupt race 2007-11-16T17:30:22+00:00 Benedikt Spranger bene@linutronix.de 2007-10-12T22:18:59+00:00 bdef0ae05e53c9681bdb3367ca1d461e8c2277f5 patch 5395353e0c8272fe73ac914acd7e4add0da2bef0 in mainline. Fix a longstanding race in the Ethernet gadget driver, which can cause an oops on device disconnect. The fix is just to make the TX path check whether its freelist is empty. That check is otherwise not necessary, since the queue is always stopped when that list empties (and restarted when request completion puts an entry back on that freelist). The race window starts when the network code decides to transmit a packet, and ends when hard_start_xmit() grabs the freelist lock. When disconnect() is called inside that window, it shuts down the TX queue and breaks the otherwise-solid assumption that packets are never sent through a TX queue that's stopped.

USB: remove USB_QUIRK_NO_AUTOSUSPEND 2007-11-16T17:30:22+00:00 Alan Stern stern@rowland.harvard.edu 2007-10-12T22:18:49+00:00 9b525df252728a6900fb03f6bec436aba35e03bf patch a691efa9888e71232dfb4088fb8a8304ffc7b0f9 in mainline. This patch (as995) cleans up the remains of the former NO_AUTOSUSPEND quirk. Since autosuspend is disabled by default, we will let userspace worry about which devices can safely be suspended. Thus the lengthy series of quirk entries is no longer needed, and neither is the quirk ID. I suppose someone might eventually run across a hub that can't be suspended; let's ignore the possibility for now. The patch also cleans up the hasty way in which autosuspend gets disabled. Setting udev->autosuspend_delay to -1 wasn't quite right, because the value is always supposed to be a multiple of HZ. It's better to leave the delay value alone and set autosuspend_disabled, which is what the quirk routine used to do.
