…improved PrntScr hotkey handling + Added Vendor Specific Message with code 151 (0x97) to ApplePS2Device used to request Trackpad resets from Keypad controller. - VoodooPS2Keyboard now requests a Trackpad reset too when the 3-finger salute (Ctrl+Alt+Del) is pressed on the Keypad. + Fix: Added an extra kDP_Enable command request on VoodooPS2SynapticsTouchPad when waking from sleep. This should auto-enable reluctant Synaptics touchpads on wake. + Added handling code for resetTouchpad IOkit messages on VoodooPS2SynapticsTouchPad, to actually reset and re-enable the device on request. - Bumped module version to 2.1.6 TL;DR: This commit tries to fix some Synaptics touchpad devices not working after waking from sleep. If that doesnt work automatically after a couple of seconds, press Ctrl+Alt+Del to issue a device reset. This can be done at any time. Dev note: It may be a good idea to implement the the reset message handling on any other touchpad driver too, this should give users a keyboard combo command to try to recover from non-working scenarios, before giving up and rebooting. (+1 squashed commit) Squashed commits: [3e7fb81] Remapped Touchpad reset to PrntScr and cleaned up special hotkey handling - Ctrl+Alt+PrntScrn key combo is now used to trigger Touchpad resets. This should fix collisions with Ctrl+Alt+Del on VMs/RDPs. - Cleaned and improved special hotkey handling on VoodooPS2Keyboard.cpp around the PrntScr/SysRq key. - VoodooPS2Keyboard now detect and correctly maps the SysRq key or the Alt+PrntScrn key combo, instead of just ignoring it. + VoodooPS2Keyboard now detects modifiers pressed on any side of the keyboard when handling special PrntScr hotkeys. - The keyboard module is now more verbose to the IOLog when built with DEBUG configurations. + Keyboard and Touchpad "Enabled" states are now synced up when using the Windows/Logo+PrntSrc keyboard combo. Both of them are disabled, or both enabled. + Pressing Shift+PrntSrc now sends a SysRq key instead, useful for VMs and RDPs, specially Linux-based ones. - Devs: Added inline method checkModifierStateAny(UInt16) to VoodooPS2Keyboard.h. This should allow a more flexible way to check if a modifier key is present without taking into account other modifier keys. The current list of supported hotkeys by VoodooPS2Keyboard are as follows: Supported Voodoo PrntScr Key combinations: - PrntScr: Enable/Disable touchpad - Windows+PrntScr: Enable/Disable touchpad+keyboard - Ctrl+Alt+PrntScr: Reset and enable touchpad - Shift+PrntScr: Send SysRq scancode to the kernel
-- Removed touchpad reset signal dispatching code from VoodooPS2Keyboard.cpp. This change complements the previous commit.
