2011-01-14xHCI: replace dev_dbg() with xhci_dbg()Andiry Xu
dev_dbg() is used to print ordinary transfer messages in xhci-ring.c. System log messages will be flushed if CONFIG_USB_DEBUG is set. Replace the dev_dbg() with xhci_dbg(). Signed-off-by: Andiry Xu <andiry.xu@amd.com> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>
2011-01-14xHCI: fix cycle bit set in giveback_first_trb()Andiry Xu
giveback_first_trb() controls the cycle bit set of the start_trb, to ensure that the start_trb is written last and the host controller will receive a whole td at a time. However, if the ring is wrapped and cycle bit is toggled to zero, then giveback_first_trb() will be of no effect. In this case, set the cycle bit of start_trb to 1 at the beginning and clear it in giveback_first_trb().

2011-01-14xhci: Use GFP_NOIO during device reset.Sarah Sharp
When xhci_discover_or_reset_device() is called after a host controller power loss, the virtual device may need to be reallocated. Make sure xhci_alloc_dev() uses GFP_NOIO. This avoid causing a deadlock by allowing the kernel to flush pending I/O while reallocating memory for a virtual device for a USB mass storage device that's holding the backing store for dirty memory buffers. This patch should be queued for the 2.6.37 stable tree. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Cc: stable@kernel.org
2011-01-14usb: Realloc xHCI structures after a hub is verified.Sarah Sharp
When there's an xHCI host power loss after a suspend from memory, the USB core attempts to reset and verify the USB devices that are attached to the system. The xHCI driver has to reallocate those devices, since the hardware lost all knowledge of them during the power loss. When a hub is plugged in, and the host loses power, the xHCI hardware structures are not updated to say the device is a hub. This is usually done in hub_configure() when the USB hub is detected. That function is skipped during a reset and verify by the USB core, since the core restores the old configuration and alternate settings, and the hub driver has no idea this happened. This bug makes the xHCI host controller reject the enumeration of low speed devices under the resumed hub. Therefore, make the USB core re-setup the internal xHCI hub device information by calling update_hub_device() when hub_activate() is called for a hub reset resume. After a host power loss, all devices under the roothub get a reset-resume or a disconnect. This patch should be queued for the 2.6.37 stable tree.

2011-01-14xHCI: synchronize irq in xhci_suspend()Andiry Xu
Synchronize the interrupts instead of free them in xhci_suspend(). This will prevent a double free when the host is suspended and then the card removed. Set the flag hcd->msix_enabled when using MSI-X, and check the flag in suspend_common(). MSI-X synchronization will be handled by xhci_suspend(), and MSI/INTx will be synchronized in suspend_common(). This patch should be queued for the 2.6.37 stable tree.

2011-01-14xhci: Resume bus on any port status change.Sarah Sharp
The original code that resumed the USB bus on a port status change would only do so when there was a device connected to the port. If a device was just disconnected, the event would be queued for khubd, but khubd wouldn't run. That would leave the connect status change (CSC) bit set. If a USB device was plugged into that same port, the xHCI host controller would set the current connect status (CCS) bit. But since the CSC bit was already set, it would not generate an interrupt for a port status change event. That would mean the user could "Safely Remove" a device, have the bus suspend, disconnect the device, re-plug it in, and then the device would never be enumerated. Plugging in a different device on another port would cause the bus to resume, and khubd would notice the re-connected device. Running lsusb would also resume the bus, leading users to report the problem "went away" when using diagnostic tools. The solution is to resume the bus when a port status change event is received, regardless of the port status. Thank you very much to Maddog for helping me track down this Heisenbug. This patch should be queued for the 2.6.37 stable tree.

2011-01-08hwmon: (applesmc) Dynamic creation of fan filesHenrik Rydberg
With the dynamic temperature group in place, the setup of fans can be simplified. This patch sets up the fans dynamically, removing a hundred lines of code. Signed-off-by: Henrik Rydberg <rydberg@euromail.se> Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com>
2011-01-08hwmon: (applesmc) Extract all features genericallyHenrik Rydberg
With temperature keys being determined automatically, the dmi match data is only used to assign features that can easily be detected from the smc. This patch removes the dmi match data altogether, and reduces the match table to the main machine models.

2011-01-08hwmon: (applesmc) Handle new temperature formatHenrik Rydberg
The recent Macbooks have temperature registers of a new type. This patch adds the logic to handle them. Signed-off-by: Henrik Rydberg <rydberg@euromail.se> Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com>
2011-01-08hwmon: (applesmc) Dynamic creation of temperature filesHenrik Rydberg
The current driver creates temperature files based on a list of temperature keys given per device. Apart from slow adaption to new machine models, the number of sensors also depends on the number of processors. This patch looks up the temperature keys dynamically, thereby supporting all models.

2011-01-08hwmon: (applesmc) Introduce a register lookup tableHenrik Rydberg
One main problem with the current driver is the inability to quickly search for supported keys, resulting in detailed feature maps per machine model which are cumbersome to maintain. This patch adds a register lookup table, which enables binary search for supported keys. The lookup also reduces the io frequency, so the original mutex is replaced by locks around the actual io.

2011-01-08hwmon: (applesmc) Relax the severity of device init failureHenrik Rydberg
The device init is used to reset the accelerometer. Failure to reset is not severe enough to stop loading the module or to resume from hibernation. This patch relaxes failure to a warning and drops output in case of success.
