| | | | | | | | | | | | | | | | | | | | | | On multi-platform kernels, the Amiga joystick driver may be initialized when running on Amiga only. Else it may crash later. Fortunately this driver is almost always compiled as a module (to avoid conflicts with the mouse driver), so it needs an explicit insmod to trigger a crash.

| * Input: wacom - create inputs when wireless connectChris Bagwell2012-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a tablet connect or disconnect is detected, schedule work queue to register or unregister related input devices. When a wireless tablet connects, it reports same USB PID used if tablet is connected with USB cable. Use this to update features values, set input capabilities, and then register device. From there, the Pen and Touch interfaces will reuse the existing tablet's IRQ routines. Its possible that 1 receiver is shared with 2 tablets with different PID (small and medium Bamboo for example) so the input is unregister at disconnect to better support this case.

| * Input: wacom - wireless monitor frameworkChris Bagwell2012-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 3rd gen Bamboo Pen & Touch and Intuos5 tablets support an optional wireless module. When its receiver is plugged into USB, it presents 3 interfaces: 0) Monitor 1) Pen and 2) Touch. The exact capabilities of the Pen and Touch interfaces can not be determined until a tablet connection is established and reported over the Monitor interface. This patch detects this wireless receiver and enables interrupt packets to be processed for the Monitor interface. Processing the data in packets will be left to another patch. Since it doesn't make sense to create an input device for the Monitor interface, it is not created. Creation of Pen and Touch input device is also delayed until monitor packets can be processed.

The older hardware performs much better in relative mode; thus relative mode related code are preserved. Part of the code is based on the work done by Oskari Saarenmaa <os@ohmu.fi>, which was used to support the clickpad found on ASUS UX21/31 Ultrabook. On the other hand, the FSP found on UX21/31 doesn't have hardware capability register other than PnP ID, which means that we'll have to figure out an alternative approach to identify such pad correctly; otherwise, blindly adding INPUT_PROP_BUTTONPAD property may compatability issues amongst existing FSPs.

But now they are actually 20 bit. So the fix is simplicity itself. I've tested with 300 devices and all user-mode utils work just fine. I have also mechanically added 10,000 to the ida (so devices are /dev/osd10000, /dev/osd10001 ...) and was able to mkfs an exofs filesystem and access osds from user-mode. All the open-osd user-mode code uses the same library to access devices through their symbolic names in /dev/osdX so I'd say it's pretty safe. (Well tested) This patch is very important because some of the systems that will be deploying the 3.2 pnfs-objects code are larger than 64 OSDs and will stop to work properly when reaching that number.

Adding empty body defitions in the !CONFIG_PCI case, which is what this patch does, breaks the parisc compile because the functions become doubly defined. It took us a while to spot this, because we don't actually build !CONFIG_PCI very often (only if someone is brave enough to test the snake/asp machines). Since the note in the commit log says this is to fix a CONFIG_GENERIC_IOMAP issue (which it does because CONFIG_GENERIC_IOMAP supplies pci_iounmap only if CONFIG_PCI is set), there should actually have been a condition upon this. This should make sure no other architecture's !CONFIG_PCI compile breaks in the same way as parisc. The fix had to be updated to take account of the GENERIC_PCI_IOMAP separation.

This patch works around this issue by masking out the HO bit in the performance counter control register when SVM is not enabled. The GO bit is not touched because it is only set when the user wants to count in guest-mode only. So when SVM is disabled the counter should not run at all and the not-counting is the intended behaviour.

The corresponding registers are then read-only. If the user tries it nonetheless, error out with EINVAL instead of silently doing nothing.

Make the driver detect the latter mode, and expose the different modes in sysfs as per pwm_enable, so that the user can switch between them. The interpretation of the pwm_enable attribute for the F75387 is adjusted to be a superset of those values used for similar Fintek chips which do not support automatic duty mode, with 2 mapping to automatic speed mode, and moving automatic duty mode to the new value 4. Toggling the duty mode via pwm_enable is currently denied for the F75387, as the chip then simply reinterprets the fan configuration register values according to the new mode, switching between RPM and PWM units, which makes this a dangerous operation. This patch introduces a new pwm mode into the driver. This is necessary because the new mode (automatic pwm mode, 4) may already be enabled by the BIOS, and the driver should not break existing functionality. This was seen on at least one board.
