Hi All,
I have been working on adding a feature as a proof of concept to
improve the performance of applications like Looking Glass by avoiding
additional memory copies
I can confirm that these patches work as expected. Thank you kindly Alex
for your hard work!

This fixes an issue by adding bounds checking to multi-byte packets
where the PS/2 mouse data stream may become corrupted due to data
being discarded when the PS/2 ringbuffer is full.
Interrupts for Multi-byte responses are postponed until the final
byte has been queued.
These changes fix a bug

Hi All,
I am having some very strange issues with Qemu and memory copy
