Vladimir Kondratyev bedf31ad7e psm(4): Disable KVM switch "jitter" clamping for absolute touchpads. ... r123442 introduced solution for clamping of PS/2 mice jitter when using a KVM. Solution is to buffer mouse packets for 0.050ms if mouse activity has not been seen for more than 0.5 seconds. Then flush that data to driver if no validation errors found or drop the entire queue otherwise. While it works well with relative devices it has issues with absolute ones Depending on history buffering may results in delaying of the touch front edge for 0.050ms that affects gesture processing (tap detection). As absolute touchpads usually are built-in devices we can safely disable bufferization and KVM jitter clamping to avoid such a delays. MFC after: 2 weeks		2021-09-10 00:37:40 +03:00
