Hi Greg, Thanks for the confirmation! I didn't use the APIs before. I think I need a couple of days to code, test and debug it while I have many things at hand at present. :-(

The driver can build(compile) fine. The issue is: the latest Arch Linux release doesn't have a working (virtual) keyboard when it runs as Generation 2 hyper-v guest -- when it runs as a "traditional" Generation 1 hyper-v guest, everything works fine. I hope this patch can temporarily help Arch users if they find the issue and if they can rebuild the kernel. > > BTW, looks most of Linux distros (like RHEL, Ubuntu, SUSE) have > > CONFIG_SERIO_I8042=y, probably because it's the result of > > "make defconfig".
