Input: vmmouse - remove port reservation

2016-07-11T00:20:03Z

[ Upstream commit 60842ef8128e7bf58c024814cd0dc14319232b6c ] The VMWare EFI BIOS will expose port 0x5658 as an ACPI resource. This causes the port to be reserved by the APCI module as the system comes up, making it unavailable to be reserved again by other drivers, thus preserving this VMWare port for special use in a VMWare guest. This port is designed to be shared among multiple VMWare services, such as the VMMOUSE. Because of this, VMMOUSE should not try to reserve this port on its own. The VMWare non-EFI BIOS does not do this to preserve compatibility with existing/legacy VMs. It is known that there is small chance a VM may be configured such that these ports get reserved by other non-VMWare devices, and if this ever happens, the result is undefined.

Input: vmmouse - fix absolute device registration

2016-02-23T05:49:36Z

[ Upstream commit d4f1b06d685d11ebdaccf11c0db1cb3c78736862 ] We should set device's capabilities first, and then register it, otherwise various handlers already present in the kernel will not be able to connect to the device.

Input: add vmmouse driver

2015-04-14T21:29:03Z

VMMouse enables low-latency mouse-cursor-movements for VMWare and QEMU guests. By removing the guest cursor and using the host as a guest cursor the cursor movement appears instant although in reality there is some lag. To be able to do this, the host's view of the cursor position must exactly match the guest's view and an absolute pointer device is needed. Enter the VMMouse. While the VMMouse driver has historically been an Xorg user-space driver, implementing it as a kernel imput driver enables rootless Xorg and new compositing display servers for VMware guests.
