2008-07-22USB: use reset_resume when normal resume failsAlan Stern1-2/+5
This patch (as1109b) makes USB-Persist more resilient to errors. With the current code, if a normal resume fails, it's an unrecoverable error. With the patch, if a normal resume fails (and if the device is enabled for USB-Persist) then a reset-resume is tried. This fixes the problem reported in Bugzilla #10977.

2008-07-22usb gadget: use new serial coreDavid Brownell1-9/+26
Teach "gadget serial" to use the new abstracted (and bugfixed) TTY glue, and remove all the orignal tangled-up code. Update the documentation accordingly. This is a net object code shrink and cleanup; it should make it a lot easier to see how the TTY glue should accomodate updates to the TTY layer, be bugfixed, etc. Notable behavior changes include: it can now support getty even when there's no USB connection; it fits properly into the mdev/udev world; and RX handling is better (throttling works, and low latency). Configurations with scripts setting up the /dev/ttygserial device node (with "experimental" major number) may want to change that to be a symlink pointing to the /dev/ttyGS0 file, as a migration aid; else, just switch entirely over to mdev/udev.

2008-04-25USB: check serial-number string after device resetAlan Stern1-4/+4
This patch (as1048) extends the descriptor checking after a device is reset. Now the SerialNumber string descriptor is compared to its old value, in addition to the device and configuration descriptors. As a consequence, the kmalloc() call in usb_string() is now on the error-handling pathway for usb-storage. Hence its allocation type is changed to GFO_NOIO.

2008-04-25USB: remove CONFIG_USB_PERSIST settingAlan Stern1-16/+19
This patch (as1047) removes the USB_PERSIST Kconfig option, enabling it permanently. It also prevents the power/persist attribute from being created for hub devices; there's no point in having it since USB-PERSIST is always turned on for hubs.

2007-07-13USB: usb/dma doc updatesDavid Brownell1-15/+37
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?)

2007-07-13USB: add power/persist device attributeAlan Stern1-13/+25
This patch (as920) adds an extra level of protection to the USB-Persist facility. Now it will apply by default only to hubs; for all other devices the user must enable it explicitly by setting the power/persist device attribute. The disconnect_all_children() routine in hub.c has been removed and its code placed inline. This is the way it was originally as part of hub_pre_reset(); the revised usage in hub_reset_resume() is sufficiently different that the code can no longer be shared. Likewise, mark_children_for_reset() is now inline as part of hub_reset_resume(). The end result looks much cleaner than before. The sysfs interface is updated to add the new attribute file, and there are corresponding documentation updates.

2007-07-13USB: add USB-Persist facilityAlan Stern1-0/+144
This patch (as886) adds the controversial USB-persist facility, allowing USB devices to persist across a power loss during system suspend. The facility is controlled by a new Kconfig option (with appropriate warnings about the potential dangers); when the option is off the behavior will remain the same as it is now. But when the option is on, people will be able to use suspend-to-disk and keep their USB filesystems intact -- something particularly valuable for small machines where the root filesystem is on a USB device!

2007-02-08USB: add binary API to usbmonPete Zaitcev1-2/+150
This patch adds a new, "binary" API in addition to the old, text API usbmon had before. The new API allows for less CPU use, and it allows to capture all data from a packet where old API only captured 32 bytes at most. There are some limitations and conditions to this, e.g. in case someone constructs a URB with 1GB of data, it's not likely to be captured, because even the huge buffers of the new reader are finite. Nonetheless, I expect this new capability to capture all data for all real life scenarios. The downside is, a special user mode application is required where cat(1) worked before. I have sample code at http://people.redhat.com/zaitcev/linux/ and Paolo Abeni is working on patching libpcap. This patch was initially written by Paolo and later I tweaked it, and we had a little back-and-forth. So this is a jointly authored patch, but I am submitting this I am responsible for the bugs.

2006-09-27USB: Dealias -110 code (more complete)Pete Zaitcev1-7/+4
The purpose of this patch is to split off the case when a device does not reply on the lower level (which is reported by HC hardware), and a case when the device accepted the request, but does not reply at upper level. This redefinition allows to diagnose issues easier, without asking the user if the -110 happened "immediately". The usbmon splits such cases already thanks to its timestamp, but it's not always available. I adjusted all drivers which I found affected (by searching for "urb"). Out of tree drivers may suffer a little bit, but I do not expect much breakage. At worst they may print a few messages.
