And I am not familiar with VMbus :-) > IIRC, for every mouse event, the Hyper-V host sends > a 7-byte "input_report", which in Linux VM is handled > by the Linux HID API hid_input_report() and nothing else is done. > In FreeBSD, I'm not sure what the equivalent API is? intr_handler callback sends input report body to upper layers. See e.g. iic= hid driver: https://github.com/freebsd/freebsd-src/blob/main/sys/dev/iicbus/iichid.c#L5= 83. The callback is registered with intr_setup method https://github.com/freebsd/freebsd-src/blob/main/sys/dev/hid/hid_if.m#L50. > I suppose the format of the 7 bytes from the Hyper-V host > should comply with the HID spec for mouse As it is not a boot protocol which takes only 3 bytes, it should be prescri= bed in HID report descriptor. I think it lies in one of the Linux header files. > I guess Wei (whu) on our team can help on this, and also review the 2 kbd= patches. That would be great! Thanks! If someone familiar with VMbus would write dri= ver capable to just print these 7 bytes, I would easily connect it to our HID A= PI. --=20 You are receiving this mail because: You are the assignee for the bug.=
