The max packet length bit mask used for isochronous endpoints should be 0x7FF instead of 0x8FF. 0x8FF will actually clear higher-order bits in the max packet length field. This patch applies to 2.6.34-rc6. Signed-off-by:

When a device is disconnected, xhci_free_virt_device() is called. Ramya found that if the device had streams enabled, and then the driver freed the streams with a call to usb_free_streams(), then about a minute after he had called this, his machine crashed with a Bad DMA error. It turns out that xhci_free_virt_device() would attempt to free the endpoint's stream_info data structure if it wasn't NULL, and the free streams function was not setting it to NULL after freeing it.

Fix mos7720 Kconfig dependencies. When an enabled bool selects a tristate, the tristate becomes =y, even if it should be limited to modular, so limit the bool kconfig option to configs that will build cleanly. Also change the if-block to a simple depends on. drivers/built-in.o: In function `mos7720_release': mos7720.c:(.text+0xad432): undefined reference to `parport_remove_port' drivers/built-in.o: In function `mos7715_parport_init': mos7720.c:(.text+0xae197): undefined reference to `parport_register_port' mos7720.c:(.text+0xae210): undefined reference to `parport_announce_port' drivers/built-in.o:(.data+0x201c8): undefined reference to `parport_ieee1284_read_nibble' drivers/built-in.o:(.data+0x201d0): undefined reference to `parport_ieee1284_read_byte' Signed-off-by:

No functionality added or bugs fixed, just improved code consistency and (hopefully) readability by replacing send_mos_cmd with the register read & write functions that were used for parallel port registers. Also shortens overall file length. Thoroughly tested, with emphasis on regression testing the serial port. Signed-off-by:

Add support for the parallel port on the moschip MCS7715 device. The port registers itself with the parport subsystem as a low-level driver. A separate entry to the kernel configuration is added beneath that for the mos7720, to avoid the need to link with the parport subsystem code for users who don't have or don't want the parallel port. Only compatibility mode is currently supported (no ECP/EPP). Tested with both moschip devices (7720 and 7715) on UP and SMP hosts, including regression testing of serial port, concurrent operation of serial and parallel ports, and various connect / disconnect scenarios.

Daniel Mack authored
For more clearance what the functions actually do, usb_buffer_alloc() is renamed to usb_alloc_coherent() usb_buffer_free() is renamed to usb_free_coherent() They should only be used in code which really needs DMA coherency. All call sites have been changed accordingly, except for staging drivers. Signed-off-by:

It seems unlikely that this entry is needed anymore since the kernel has logic to handle devices that poorly respond to INQUIRY. Since we now have another entry with the same VID/PID but different flags, it's a good time to attempt to clean this up. The original submitter's email no longer works, so we'll keep an eye out for any regression reports. Signed-off-by:

Bulk endpoint streams were added in the USB 3.0 specification. Streams allow a device driver to overload a bulk endpoint so that multiple transfers can be queued at once. The device then decides which transfer it wants to work on first, and can queue part of a transfer before it switches to a new stream. All this switching is invisible to the device driver, which just gets a completion for the URB. Drivers that use streams must be able to handle URBs completing in a different order than they were submitted to the endpoint. This requires adding new API to set up xHCI data structures to support multiple queues ("stream rings") per endpoint. Drivers will allocate a number of stream IDs before enqueueing URBs to the bulk endpoints of the device, and free the stream IDs in their disconnect function. See Documentation/usb/bulk-streams.txt for details. The new mass storage device class, USB Attached SCSI Protocol (UASP), uses these streams API. Signed-off-by: -

Much of the xHCI driver code assumes that endpoints only have one ring. Now an endpoint can have one ring per enabled stream ID, so correct that assumption. Use functions that translate the stream_id field in the URB or the DMA address of a TRB into the correct stream ring. Correct the polling loop to print out all enabled stream rings. Make the URB cancellation routine find the correct stream ring if the URB has stream_id set. Make sure the URB enqueueing routine does the same. Also correct the code that handles stalled/halted endpoints. Check that commands and registers that can take stream IDs handle them properly. That includes ringing an endpoint doorbell, resetting a stalled/halted endpoint, and setting a transfer ring dequeue pointer (since that command can set the dequeue pointer in a stream context or an endpoint context). Correct the transfer event handler to translate a TRB DMA address into the stream ring it was enqueued to. Make the code to allocate and prepare TD structures adds the TD to the right td_list for the stream ring. Make sure the code to give the first TRB in a TD to the hardware manipulates the correct stream ring. When an endpoint stalls, store the stream ID of the stream ring that stalled in the xhci_virt_ep structure. Use that instead of the stream ID in the URB, since an URB may be re-used after it is given back after a non-control endpoint stall. Signed-off-by:
