* uhci-hcd: fix list access bugAlan Stern2006-08-31
| | | | | | | | | | When skipping to the last TD of an URB, go to the _last_ entry in the list instead of the _first_ entry (as780). This fixes Bugzilla #6747 and possibly others. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* UHCI: don't stop at an Iso errorAlan Stern2006-08-31
| | | | | | | | | | | Unlike other sorts of endpoint queues, Isochronous queues don't stop when an error is encountered. This patch (as772) fixes the scanning routine in uhci-hcd, to make it keep on going when it finds an Iso error.

* USB: UHCI: Don't test the Short Packet Detect bitAlan Stern2006-08-02
| | | | | | | | | | | | | | | | Apparently some UHCI controllers change the value of the Short Packet Detect (SPD) bit in the TD status word -- presumably when they receive a short packet. This patch (as759) changes uhci-hcd to avoid assuming that the bit is unchanged; in fact, the driver no longer looks at SPD at all. This fixes the second problem reported in Bugzilla #6752.

* [PATCH] USB: ehci: fix bogus alteration of a local variableDavid Brownell2006-07-12
| | | | | | | | | | | | | | | | In a rare and all-but-unused path, the EHCI driver could reuse a variable in a way that'd make trouble. Specifically, if the first root hub port gets an overcurrent event (rare) during a remote wakeup scenario (all but unused in today's Linux, except for folk working with suspend-to-RAM and similar sleep states), that would look like a fatal error which would shut down the controller. Fix by not reusing that variable.

* [PATCH] USB: au1200: EHCI and OHCI fixesDaniel Mack2006-07-12
| | | | | | | | | | | | | | | | | | | | I received an DBAU1200 eval kit from AMD a few days ago and tried to enable the USB2 port, but the current linux-2.6 GIT did not even compile with CONFIG_SOC_1200, CONFIG_SOC_AU1X00, CONFIG_USB_EHCI and CONFIG_USB_OHCI set. Furthermore, in ehci-hcd.c, platform_driver_register() was called with an improper argument of type 'struct device_driver *' which of course ended up in a kernel oops. How could that ever have worked on your machines? Anyway, here's a trivial patch that makes the USB subsystem working on my board for both OHCI and EHCI. It also removes the /* FIXME use "struct platform_driver" */.

* [PATCH] UHCI: Improve FSBR-off timingAlan Stern2006-06-21
| | | | | | | | | | | | This patch (as707) improves the FSBR operation in uhci-hcd by turning it off more quickly when it isn't needed. FSBR puts a noticeable load on a computer's PCI bus, so it should be disabled as soon as possible when it isn't in use. The patch leaves it running for only 10 ms after the last URB stops using it, on the theory that this should be long enough for a driver to submit another URB if it wants keep FSBR going.

It's not needed because it conveys exactly the same information as the generic HCD_FLAG_HW_ACCESSIBLE bit. In its place goes a new flag recording whether the controller is dead.

With the following code ret = ep->branch = balance(isp116x, ep->period, ep->load); if (ret < 0) goto fail; the problem is that ret and balance are of the type int, and ep->branch is u16. so the int balance() returns gets reduced to u16 and then converted to an int again, which removes the sign. Maybe the following little c program can explain it better:
* [PATCH] improved TT scheduling for EHCIDan Streetman2006-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | This updates the EHCI driver by adding an improved scheduler for the transaction translators, found in USB 2.0 hubs and used for low and full speed devices. - adds periodic_tt_usecs() and some helper functions, which does the same thing that "periodic_usecs" does, except on the other side of the TT, i.e. it calculates the low/fullspeed bandwidth usage instead of highspeed. - adds a tt_available() function which is the new implementation of what tt_no_collision() does ... while tt_no_collision() ensures that each TT handles only 1 periodic transfer at a time (a very pessimistic approach) this version instead tracks bandwidth and allows each TT to handle as many transfers as will fit on each TT's downstream bus (closer to best-case). The new scheduler is selected by a config option, marked as EXPERIMENTAL so it can be tested (and more broadly reviewed) for a while until it seems safe to remove the original scheduler.

* [PATCH] UHCI: remove ISO TDs as they are usedAlan Stern2006-06-21
| | | | | | | | | | | | This patch (as690) does the same thing for ISO TDs as as680 did for non-ISO TDs: free them as they are used rather than all at once when an URB is complete. At the same time it fixes a minor buglet (I'm not aware of it ever affecting anyone): An ISO TD should be retired when its frame is over, regardless of whether or not the hardware has marked it inactive.

* [PATCH] UHCI: store the period in the queue headerAlan Stern2006-06-21
| | | | | | | | | | | This patch (as689) stores the period for periodic transfers (interrupt and ISO) in the queue header. This is necessary for proper bandwidth tracking (not yet implemented). It also makes the scheduling of ISO transfers a bit more rigorous, with checks for out-of-bounds frame numbers.

* [PATCH] UHCI: fix race in ISO dequeuingAlan Stern2006-06-21
| | | | | | | | | | | | This patch (as688) fixes a small race in uhci-hcd. Because ISO queues aren't controlled by queue headers, they can't be unlinked. Only individual URBs can. So whenever multiple ISO URBs are dequeued, it's necessary to make sure the hardware is done with each one. We can't assume that dequeuing the first URB will suffice to unlink the entire queue.

* [PATCH] UHCI: use integer-sized frame numbersAlan Stern2006-06-21
| | | | | | | | | | This patch (as687) changes uhci-hcd to keep track of frame numbers as full-sized integers rather than 11-bit values.

* [PATCH] UHCI: Reimplement FSBRAlan Stern2006-06-21
| | | | | | | | | | | | This patch (as683) re-implements Full-Speed Bandwidth Reclamation (FSBR) properly. It keeps track of which endpoint queues have advanced, and when none have advanced for a sufficiently long time, FSBR is turned off. The next TD on each of the non-moving queues is modified to generate an interrupt on completion, so that FSBR can be re-enabled as soon as the hardware starts to make some progress.

| | | | | | | | | | This patch (as682) gets rid of the TD-removal list in uhci-hcd. It is no longer needed because now TDs are not freed until we know the hardware isn't using them.

| | | | | | | | | | | This patch (as680) frees non-isochronous TDs as they are used, rather than all at once when an URB is complete.

| | | | | | | | | | | This patch (as676) fixes a small bug in uhci-hcd's enqueue routine.
