* [PATCH] USB: move hardware-specific <linux/usb_*.h> to <linux/usb/*.h>David Brownell2006-06-21
| | | | | | | | | This moves header files for controller-specific platform data from <linux/usb_XXX.h> to <linux/usb/XXX.h> to start reducing some clutter. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [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.

* [PATCH] UHCI: remove hc_inaccessible flagAlan Stern2006-06-21
| | | | | | | | | | | | | This patch (as706) removes the private hc_inaccessible flag from uhci-hcd. 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. The new code allows a complete device reset to resurrect a dead controller (although usbcore doesn't yet implement such a facility).

* [PATCH] UHCI: various updatesDavid Brownell2006-06-21
| | | | | | | | | | | | | | | | | | | | This patch (as705) contains a small set of updates for uhci-hcd written mostly by Dave Brownell: * Root hub suspend messages come out labeled as root hub messages; PCI messages should only come out when the pci device suspends. * Rename the reset() method to better match its init() role * Behave more like the other HCDs by returning -ESHUTDOWN for root-hub suspend/resume errors. * When an URB fails, associate the message with the usb device not the host controller (it still hides endpoint and direction) From: David Brownell <david-b@pacbell.net> Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] USB: negative index in drivers/usb/host/isp116x-hcd.cEric Sesterhenn2006-06-21
| | | | | | | | | | | | | | | | From: Eric Sesterhenn <snakebyte@gmx.de> This fixes coverity Bug #390. 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 (as676) fixes a small bug in uhci-hcd's enqueue routine. When an URB is unlinked or gets an error and the completion handler queues another URB for the same endpoint, the queue shouldn't be allowed to start up again until the handler returns.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of reorienting uhci-hcd away from URBs and toward endpoint queues, this patch (as625) eliminates the driver's main list of URBs. The list wsa used mainly in checking for URB completions; now the driver goes through the list of active endpoints and checks the members of the queues. As a side effect, I had to remove the code that looks for FSBR timeouts. For now, FSBR will remain on so long as any URBs on a full-speed control or bulk queue request it, even if the queue isn't advancing. A later patch can add more intelligent handling. This isn't a huge drawback; it's pretty rare for an URB to get stuck for more than a fraction of a second. (And it will help the people trying to use those insane HP USB devices.)

| * [PATCH] UHCI: use dummy TDsAlan Stern2006-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as624) fixes a hardware race in uhci-hcd by adding a dummy TD to the end of each endpoint's queue. Without the dummy the host controller will effectively turn off the queue when it reaches the end, which happens asynchronously. This leads to a potential problem when new transfer descriptors are added to the end of the queue; they may never get used. With a dummy TD present the controller never turns off the queue; instead it just stops at the dummy and leaves the queue on but inactive. When new TDs are added to the end of the queue, the first new one gets written over the dummy. Thus there's never any question about whether the queue is running or needs to be restarted.

It no longer uses the hcd glue bits with those roles, and depends on the previous patch making the root hub available earlier. Note that on most platforms (boot code properly setting the RWC bit) this gives a partial workaround for the way PCI isn't currently flagging devices that support PME# signals. (Because of odd PCI init sequencing on PPC.) That's because many OHCI controllers support "legacy PCI PM" ... without involving any PCI PM capability.
