* USB: serial: don't call release without attachAlan Stern2009-10-09
| | | | | | | | | | | | | | | | | This patch (as1295) fixes a recently-added bug in the USB serial core. If certain kinds of errors occur during probing, the core may call a serial driver's release method without previously calling the attach method. This causes some drivers (io_ti in particular) to perform an invalid memory access. The patch adds a new flag to keep track of whether or not attach has been called.

| * USB: ehci-dbgp: errata for EHCI debug controller initializationJason Wessel2009-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some EHCI usb debug controllers, the EHCI debug device will fail to be seen after a port reset, after a warm reset. Two options exist to get the device to initialize correctly. Option 1 is to unplug and plug in the device. Option 2 is to use the EHCI port test to get the usb debug device to start talking again. At that point the debug controller port reset will succeed.

| * USB: ehci-dbgp,ehci: Allow early or late use of the dbgp deviceJason Wessel2009-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the EHCI debug port is initialized and in use, the EHCI host controller driver must follow two rules. 1) If the EHCI host driver issues a controller reset, the debug controller driver re-initialization must get called after the reset is completed. 2) The EHCI host driver should ignore any requests to the physical EHCI debug port when the EHCI debug port is in use. The code to check for the debug port was moved from ehci_pci_reinit() to ehci_pci_setup because it must get called prior to ehci_reset() which will clear the debug port registers.

| * USB: ehci-dbgp: stability improvements and external re-initJason Wessel2009-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements several changes: 1) Improve the capability to debug the dbgp driver The dbgp_ehci_status() was added in a number of places to report the critical ehci registers to diagnose the cause of a failure of the ehci-dbgp driver. 2) Capability to survive the host controller initialization The dbgp_external_startup(), dbgp_not_safe, and dbgp_phys_port were added so as to allow the ehci-dbgp to re-initialize after the ehci host controller is reset by the standard host controller driver. This same routine is common for the early startup or re-initialization. This resulted in the need to move some of the initialization code out of the __init section because the ehci driver has the possibility to be loaded later on as a kernel module. 3) Stability improvements for device initialization The device enumeration from 0 to 127 has the possibility to fail the first time after a warm reset on some older EHCI debug controllers. The enumeration will be tried up to 3 times to account for this failure case. The dbg_wait_until_complete() was changed to wait up to 250 ms before failing which only comes into play during device initialization. The maximum delay will never get hit during the course of normal operation of the driver, unless the device got unplugged or there was a ehci controller failure, in which case the dbgp device driver will shut itself down.

| * USB: use kfifo to buffer usb-generic serial writesDavid VomLehn2009-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When do_output_char() attempts to write a carriage return/line feed sequence, it first checks to see how much buffer room is available. If there are at least two characters free, it will write the carriage return/line feed with two calls to tty_put_char(). It calls the tty_operation functions write() for devices that don't support the tty_operations function put_char(). If the USB generic serial device's write URB is not in use, it will return the buffer size when asked how much room is available. The write() of the carriage return will cause it to mark the write URB busy, so the subsequent write() of the line feed will be ignored. This patch uses the kfifo infrastructure to implement a write FIFO that accurately returns the amount of space available in the buffer.

* USB: Parse and store the SuperSpeed endpoint companion descriptors.Sarah Sharp2009-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The USB 3.0 bus specification added an "Endpoint Companion" descriptor that is supposed to follow all SuperSpeed Endpoint descriptors. This descriptor is used to extend the bus protocol to allow more packets to be sent to an endpoint per "microframe". The word microframe was removed from the USB 3.0 specification because the host controller does not send Start Of Frame (SOF) symbols down the USB 3.0 wires. The descriptor defines a bMaxBurst field, which indicates the number of packets of wMaxPacketSize that a SuperSpeed device can send or recieve in a service interval. All non-control endpoints may set this value as high as 16 packets (bMaxBurst = 15). The descriptor also allows isochronous endpoints to further specify that they can send and receive multiple bursts per service interval. The bmAttributes allows them to specify a "Mult" of up to 3 (bmAttributes = 2). Bulk endpoints use bmAttributes to report the number of "Streams" they support. This was an extension of the endpoint pipe concept to allow multiple mass storage device commands to be outstanding for one bulk endpoint at a time. This should allow USB 3.0 mass storage devices to support SCSI command queueing. Bulk endpoints can say they support up to 2^16 (65,536) streams. The information in the endpoint companion descriptor must be stored with the other device, config, interface, and endpoint descriptors because the host controller needs to access them quickly, and we need to install some default values if a SuperSpeed device doesn't provide an endpoint companion descriptor.

* USB: Add SuperSpeed to the list of USB device speeds.Sarah Sharp2009-06-16
| | | | | | | | | | | | | | | | | | | | | | | Modify the USB core to handle the new USB 3.0 speed, "SuperSpeed". This is 5.0 Gbps (wire speed). There are probably more places that check for speed that I've missed. SuperSpeed devices have a 512 byte endpoint 0 max packet size. This shows up as a bMaxPacketSize0 set to 0x09 (see table 9-8 of the USB 3.0 bus spec). xHCI spec says that the xHC can handle intervals up to 2^15 microframes. That might change when real silicon becomes available. Add FIXME note for SuperSpeed isochronous endpoints. They can transmit up to 16 packets in one "burst" before they wait for an acknowledgment of the packets. They can do up to 3 bursts per microframe (determined by the mult value in the endpoint companion descriptor). The xHCI driver doesn't have support for isoc yet, so fix this later.

* USB: usb-serial: replace shutdown with disconnect, releaseAlan Stern2009-06-16
| | | | | | | | | | | | | | | | This patch (as1254) splits up the shutdown method of usb_serial_driver into a disconnect and a release method. The problem is that the usb-serial core was calling shutdown during disconnect handling, but drivers didn't expect it to be called until after all the open file references had been closed. The result was an oops when the close method tried to use memory that had been deallocated by shutdown.

* USB: usb-serial: call port_probe and port_remove at the right timesAlan Stern2009-06-16
| | | | | | | | | | | This patch (as1253) prevents the usb-serial core from calling a driver's port_probe and port_remove methods more than once per port. It also removes some unnecessary try_module_get() calls and adds a missing port_remove method call in a failure path.

* USB: serial: usb_debug,usb_generic_serial: implement sysrq and serial breakJason Wessel2009-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | The usb_debug driver was modified to implement serial break handling by using a "magic" data packet comprised of the sequence: 0x00 0xff 0x01 0xfe 0x00 0xfe 0x01 0xff When the tty layer requests a serial break the usb_debug driver sends the magic packet. On the receiving side the magic packet is thrown away or a sysrq is activated depending on what kernel .config options have been set. The generic serial driver was modified as well as the usb serial headers to generically implement sysrq processing in the same way the non usb uart based drivers implement the sysrq handling. This will allow other usb serial devices to implement sysrq handling as desired. The new usb serial functions are named similarly and implemented similarly to the uart functions as follows: usb_serial_handle_break <-> uart_handle_break usb_serial_handle_sysrq_char <-> uart_handle_sysrq_char Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB: usb_debug, usb_generic_serial: implement multi urb writeJason Wessel2009-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | The usb_debug driver, when used as the console, will always fail to insert the carriage return and new line sequence as well as randomly drop console output. This is a result of only having the single write_urb and that the tty layer will have a lock that prevents the processing of the back to back urb requests. The solution is to allow more than one urb to be outstanding and have a slightly deeper transmit queue. The idea and some code is borrowed from the ftdi_sio usb driver. The generic usb serial driver was modified so as to allow the classic method of 1 write urb, or a multi write urb scheme with N allowed outstanding urbs where N is controlled by max_in_flight_urbs. When max_in_flight_urbs in a "struct usb_serial_driver" is non zero the multi write urb scheme will be used. The size of 4000 was selected for the usb_debug driver so that the driver lowers possibility of losing the queued console messages during the kernel startup.
