* [PATCH] usb: Patch for USBDEVFS_IOCTL from 32-bit programsPete Zaitcev2005-10-283-14/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dell supplied me with the following test: #include<stdio.h> #include<errno.h> #include<sys/ioctl.h> #include<fcntl.h> #include<linux/usbdevice_fs.h> main(int argc,char*argv[]) { struct usbdevfs_hub_portinfo hubPortInfo = {0}; struct usbdevfs_ioctl command = {0}; command.ifno = 0; command.ioctl_code = USBDEVFS_HUB_PORTINFO; command.data = (void*)&hubPortInfo; int fd, ret; if(argc != 2) { fprintf(stderr,"Usage: %s /proc/bus/usb/<BusNo>/<HubID>\n",argv[0]); fprintf(stderr,"Example: %s /proc/bus/usb/001/001\n",argv[0]); exit(1); } errno = 0; fd = open(argv[1],O_RDWR); if(fd < 0) { perror("open failed:"); exit(errno); } errno = 0; ret = ioctl(fd,USBDEVFS_IOCTL,&command); printf("IOCTL return status:%d\n",ret); if(ret<0) { perror("IOCTL failed:"); close(fd); exit(3); } else { printf("IOCTL passed:Num of ports %d\n",hubPortInfo.nports); close(fd); exit(0); } return 0; } I have verified that it breaks if built in 32 bit mode on x86_64 and that the patch below fixes it.

* [PATCH] add usb transceiver set_suspend() methodJuha Yrj?l?2005-10-282-0/+17
| | | | | | | | | | | | | | When a USB device is put into suspend mode, the current drawn from VBUS has to be less than 500 uA. Some transceivers need to be put into a special power-saving mode to accomplish this, and won't have a separate OTG driver handling that. This adds a suspend method to the "otg_transceiver" struct -- misnamed, it's not only for OTG -- and calls it from the OMAP UDC driver.

* [PATCH] omap_udc dma off-by-one fixDavid Brownell2005-10-281-3/+5
| | | | | | | | | | | | | | The change to make DMA work two bytes at a time omitted an important tweak that affects the file_storage gadget: it needs to recognize when the host writes an odd number of bytes. (The network layer ignores such extra bytes.) This patch resolves that issue by checking the relevant bit and adjusting the rx byte count, so that for example a legal 13 byte request doesn't morph into an illegal 14 byte one any more.

* [PATCH] UHCI: Improve handling of iso TDsAlan Stern2005-10-281-13/+26
| | | | | | | | | | | | | | | | | | | | | The uhci-hcd driver is fairly lax about the way it handles isochronous transfers. This patch (as579) improves it in three respects: TDs for a new URB aren't added to the schedule until all of them have been allocated. This way there's no risk of the controller executing some of them when an allocation fails. TDs for an unlinked URB are removed from the schedule as soon as the URB is unlinked, rather than waiting until the URB is given back. This way there's no risk of the controller still executing a TD after the URB completes. The urb->error_count values are now reported correctly. Although since they aren't used in any drivers except for debug messages in the system log, probably nobody cares.

* [PATCH] USB: Rename hcd->hub_suspend to hcd->bus_suspendAlan Stern2005-10-2818-79/+72
| | | | | | | | | | | | | | | | This patch (as580) is perhaps the only result from the long discussion I had with David about his changes to the root-hub suspend/resume code. It renames the hub_suspend and hub_resume methods in struct usb_hcd to bus_suspend and bus_resume. These are more descriptive names, since the methods really do suspend or resume an entire USB bus, and less likely to be confused with the hub_suspend and hub_resume routines in hub.c. It also takes David's advice about removing the layer of bus glue, where those methods are called. And it implements a related change that David made to the other HCDs but forgot to put into dummy_hcd.

* [PATCH] UHCI: unify BIOS handoff and driver reset codeAlan Stern2005-10-282-112/+106
| | | | | | | | | | | | | | This patch (as574) updates the PCI BIOS usb-handoff code for UHCI controllers, making it work like the reset routines in uhci-hcd. This allows uhci-hcd to drop its own routines in favor of the new ones (code-sharing). Once the patch is merged we can turn the usb-handoff option on permanently, as far as UHCI is concerned.

* [PATCH] USB Storage: HP8200: Another device type detection fixDaniel Drake2005-10-281-6/+6
| | | | | | | | | | | | | | | | | | | | | | There appears to be one more case where the HP8200 CD writer devices are detected as flash readers - when the USB cable is replugged after use, with the power cable still connected. Oddly enough, the identify device command appears to 'fall through' when the devices are in this state, the status register reading exactly the same opcode as the command (0xA1) that was just executed. I think it's safe to label this behaviour as specific to HP8200 devices, I can't get the flash devices to respond like this. This patch should solve the last of the HP8200 issues which have cropped up recently.

* [PATCH] USB: usb_bulk_message() handles interrupts endpointsAlan Stern2005-10-281-4/+20
| | | | | | | | | | | | | | | | | | | | | | | | Because there is no bulk_interrupt_message() routine and no USBDEVFS_INTERRUPT ioctl, people have been forced to abuse the usb_bulk_message() routine and USBDEVFS_BULK by using them for interrupt transfers as well as bulk transfers. This patch (as567) formalizes this practice and adds code to usb_bulk_message() for detecting when the target is really an interrupt endpoint. If it is, the routine submits an interrupt URB (using the default interval) instead of a bulk URB. In theory this should help HCDs that don't like it when people try to mix transfer types, queuing both periodic and non-periodic types for the same endpoint. Not fully tested -- I don't have any programs that use USBDEVFS_BULK for interrupt transfers -- but it compiles okay and normal bulk messages work as well as before.

Previously, only CONFIG_USB_SUSPEND promised those things. (Includes updates to PCI and OMAP bus glue.) - Handle a not-noticed-before special case during resume from one of the swsusp snapshots when using "usb-handoff": the controller isn't left in RESET state.

* [PATCH] root hub updates (greater half)David Brownell2005-10-282-77/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch associates hub suspend and resume logic (including for root hubs) with CONFIG_PM -- instead of CONFIG_USB_SUSPEND as before -- thereby unifying two troublesome versions of suspend logic into just one. It'll be easier to keep things right from now on. - Now usbcore _always_ calls hcd->hub_suspend as needed, instead of only when USB_SUSPEND is enabled: * Those root hub methods are now called from hub suspend/resume; no more skipping between layers during device suspend/resume; * It now handles cases allowed by sysfs or autosuspended root hubs, by forcing the hub interface to resume too. - All devices, including virtual root hubs, now get the same treatment on their resume paths ... including re-activating all their interfaces. Plus it gets rid of those stub copies of usb_{suspend,resume}_device(), and updates the Kconfig to match the new definition of USB_SUSPEND: it provides (a) selective suspend, downstream from hubs; and (b) remote wakeup, upstream from any device configuration which supports it.

* [PATCH] root hub changes (lesser half)David Brownell2005-10-286-21/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch collects various small updates related to root hubs, to shrink later patches which build on them. - For root hub suspend/resume support: * Make the existing usb_hcd_resume_root_hub() routine respect pmcore locking, exporting and using the dpm_runtime_resume() method. * Add a new usb_hcd_suspend_root_hub() to pair with that routine. (Essential to make OHCI autosuspend behave again...) * HC_SUSPENDED by itself only refers to the root hub's downstream ports. So let HCDs see root hub URBs unless the parent device is suspended. - Remove an assertion we no longer need (and now, also don't want). - Generic suspend/resume updates to work better with swsusp. * Ignore the FREEZE vs SUSPEND distinction for hardware; trying to use it breaks the swsusp snapshots it's supposed to help (sigh). * On resume, mark devices as resumed right away, but then do nothing else if the device is marked NOTATTACHED. These changes shouldn't be very noticable by themselves.

* [PATCH] all HCDs provide root hub suspend/resume methodsDavid Brownell2005-10-286-15/+40
| | | | | | | | | | | | | | | | | | | | | This cleans up a small recent FIXME, ensuring that all the HCDs provide root hub suspend/resume methods. It also wraps the calls to those root suspend routines just like on the PCI "USB_SUSPEND not defined" cases, so non-PCI bus glue won't be as tempted to behave very differently. Several of the SOC based OHCI drivers forgot to list those methods; the patch also adds those missing declarations.

* [PATCH] EHCI, split out PCI glueMatt Porter2005-10-283-463/+489
| | | | | | | | | | | | | | | This splits BIOS and PCI specific support out of ehci-hcd.c into ehci-pci.c. It follows the model already used in the OHCI driver so support for non-PCI EHCI controllers can be more easily added.

* [PATCH] one less word in struct deviceDavid Brownell2005-10-282-24/+3
| | | | | | | | | | | | | | | This saves a word from "struct device" ... there's a refcounting mechanism stub that's rather ineffective (the values are never even tested!), which can safely be deleted. With this patch it uses normal device refcounting, so any potential users of the pm_parent mechanism will be more correct. (That mechanism is actually unusable for now though; it does nothing.)

* [PATCH] USB: UHCI: Split apart the physical and logical framelist arraysAlan Stern2005-10-284-28/+44
| | | | | | | | | | | This patch (as563) splits the physical and logical framelist arrays in uhci-hcd into two separate pieces. This will allow slightly better memory utilization, since each piece is no larger than a single page whereas before the whole thing was a little bigger than two pages. It also allows the logical array to be allocated in non-DMA-coherent memory. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] USB: UHCI: Remove unused fields and unneeded tests for NULLAlan Stern2005-10-284-43/+10
| | | | | | | | | | | | | This patch (as562) removes from the uhci-hcd driver a few unused fields and some unnecessary tests against NULL and assignments to NULL. In fact it wasn't until fairly recently that the tests became unnecessary. Before last winter it was possible that the driver's stop() routine would get called even if the start() routine returned an error, but now that can't happen. Hence there's no longer any need to check for partial initialization. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] remove some USB_SUSPEND dependenciesDavid Brownell2005-10-289-11/+12
| | | | | | | | | | | | | | | | | | | | This simplifies some of the PM-related #ifdeffing by recognizing that USB_SUSPEND depends on PM. Also, OHCI drivers were often testing for USB_SUSPEND when they should have tested just PM.
