2007-07-12USB: usb/dma doc updatesDavid Brownell2-20/+43
This patch updates some of the documentation about DMA buffer management for USB, and ways to avoid extra copying. Our understanding of the issues has improved over time. - Most drivers should *avoid* the dma-coherent allocators. There are a few exceptions (like the HID driver). - Some methods are currently commented out; it seems folk writing USB drivers aren't doing performance tuning at that level yet. - Just avoid highmem; there's no good way to pass an "I can do highmem DMA" capability through a driver stack. This is easy, everything already avoids highmem. But it'd be nice if x86_32 systems with much physical memory could use it directly with network adapters and mass storage devices. (Patch, anyone?)

Fix an oops that happens in relation with applying work arounds for buggy ftdi_sio devices.

USB_IAD: Adds support for USB Interface Association Descriptors. This patch adds support to the USB host stack for parsing, storing, and displaying Interface Association Descriptors. In /proc/bus/usb/devices lines starting with A: show the fields in an IAD. In sysfs if an interface on a USB device is referenced by an IAD the following files will be added to the sysfs directory for that interface: iad_bFirstInterface, iad_bInterfaceCount, iad_bFunctionClass, and iad_bFunctionSubClass, iad_bFunctionProtocol Signed-off-by: Craig W.

2007-07-12USB: Fix off-by-1 error in the scatter-gather libraryAlan Stern1-4/+3
The loop in usb_sg_wait() is structured in a way that makes it hard to tell, when the loop exits, whether or not the last URB submission succeeded. This patch (as928) changes it from a "for" loop to a "while" loop and keeps "i" always equal to the number of successful submissions. This fixes an off-by-one error which can show up when the first URB submission fails. The patch also removes a couple of lines that initialize fields which don't need to be initialized.

2007-07-12USB: Don't resume root hub if the controller is suspendedAlan Stern4-6/+11
Root hubs can't be resumed if their parent controller device is still suspended. This patch (as925) adds a check for that condition in hcd_bus_resume() and prevents it from being treated as a fatal controller failure. ehci-hcd is updated to add the corresponding test. Unnecessary debugging messages are removed from uhci-hcd and dummy-hcd. The error return code from dummy-hcd is changed to -ESHUTDOWN, the same as the others. ohci-hcd doesn't need any changes. Suspend handling in the non-PCI host drivers is somewhat hit-and-miss. This patch shouldn't have any effect on them.

2007-07-12USB: Remove usages of dev->power.power_stateAlan Stern2-15/+1

2007-07-12USB: usblp: add dynamic URBs, fix racesPete Zaitcev1-242/+376
This patch's main bulk aims to make usblp the premier driver for code pillaging once again. The code is as streamlined as possible and is bug-free as possible. The usb-skeleton performs the same function, but is somewhat abstract. The usblp is usb-skeleton which is actually used by many. Since I combed a few small bugs away, this also fixes the small races we had in usblp for a while. For example, now it's possible for several threads to make write(2) calls (sounds silly, but consider a printer for paper record, where every line of text is self-contained and thus it's all right to have them interleaved). Also gone are issues with interrupts using barriers dangerously. This patch makes use of Oliver's anchor, and so it must trail the anchor patch on the way to Linus.

2007-07-12USB: Add URB_FREE_BUFFER flag and the logic behind itMarcel Holtmann2-0/+4
USB: Add URB_FREE_BUFFER flag for freeing the transfer buffer In some cases it is not needed that the driver keeps track of the transfer buffer of an URB. It can be simply freed along with the URB itself when the reference count goes down to zero. The new flag URB_FREE_BUFFER enables this behavior.

2007-07-12USB: sierra: cleanup the startup and shutdown pathGreg Kroah-Hartman1-89/+41
This removes the ugly code that was copied from the keyspan driver and allocates the in urbs in a much shorter code path that can be understood easier. Also turned off the interrupt urb when no port was open as it's not nice to keep the bus busy for no good reason at all (this should be a power savings.) All in all, this saved over 40 lines of code and cleaned things up better. Cc: Kevin Lloyd <linux@sierrawireless.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-07-12USB: sierra: remove incorrect usage of the urb status fieldGreg Kroah-Hartman1-114/+107
You can't rely on the fact that the status really is correct like it was. Also simplified the write path and now we allocate the urb and data on the fly, instead of trying to do that really odd timeout check which I am guessing doesn't really work properly. This should speed up the device by keeping the hardware queue full easier. As a benefit, this reduces the size of the driver.
