c8532465 - Input: vmmouse - disable vmmouse before entering suspend mode

Wed, 18 May 2022 04:50:03 +0000

Input: vmmouse - disable vmmouse before entering suspend modeCurrently, when trying to suspend and resume with VirtualPS/2 VMMousethere is an error message after resuming: psmouse serio1: vmmouse: Unable to re-enable mouse when reconnecting, err: -6and the mouse will no longer be operable, requiring full rescan to find aanother driver to use for the port.This error is due to QEMU still generating PS2 events which the kernel isnot consuming until resume time, where they interfere with mouseidentification and ultimately resulting in an error gettingVMMOUSE_VERSION_ID.Test scenario:1) start virtual machine with qemu command "vmport=on"2) click suspend botton to enter suspend mode3) resume and observe the error message in the kernel logsLet's fix this by disabling the vmmouse in its reset handler. This willnotify qemu to stop vmmouse and remove the handler.Signed-off-by: Zongmin ZhouReviewed-by: Zack Rusin Link: https://lore.kernel.org/r/20220322021046.1087954-1-zhouzongmin@kylinos.cnSigned-off-by: Dmitry Torokhov List of files: /linux-6.15/drivers/input/mouse/vmmouse.c

60842ef8 - Input: vmmouse - remove port reservation

Fri, 24 Jun 2016 00:37:34 +0000

Input: vmmouse - remove port reservationThe VMWare EFI BIOS will expose port 0x5658 as an ACPI resource. Thiscauses the port to be reserved by the APCI module as the system comes up,making it unavailable to be reserved again by other drivers, thuspreserving this VMWare port for special use in a VMWare guest.This port is designed to be shared among multiple VMWare services, such asthe VMMOUSE. Because of this, VMMOUSE should not try to reserve this porton its own.The VMWare non-EFI BIOS does not do this to preserve compatibility withexisting/legacy VMs. It is known that there is small chance a VM may beconfigured such that these ports get reserved by other non-VMWare devices,and if this ever happens, the result is undefined.Signed-off-by: Sinclair Yeh Reviewed-by: Thomas Hellstrom Cc: # 4.1-Signed-off-by: Dmitry Torokhov List of files: /linux-6.15/drivers/input/mouse/vmmouse.c

8b8be51b - Input: add vmmouse driver

Tue, 14 Apr 2015 17:06:38 +0000

Input: add vmmouse driverVMMouse enables low-latency mouse-cursor-movements for VMWare and QEMUguests. By removing the guest cursor and using the host as a guest cursorthe 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 exactlymatch the guest's view and an absolute pointer device is needed. Enter theVMMouse. While the VMMouse driver has historically been an Xorg user-spacedriver, implementing it as a kernel imput driver enables rootless Xorg andnew compositing display servers for VMware guests.Signed-off-by: Thomas Hellstrom Signed-off-by: Dmitry Torokhov List of files: /linux-6.15/drivers/input/mouse/vmmouse.c
