Re: [Qemu-devel] [vfio-users] [PATCH v2 1/3] input: add qemu_input_qcode_to_linux + qemu_input_linux_to_qcode

[Jonathan Scruggs]

Hi Gerd,

Would there be a way to add repeating keys back in that doesn't cause issues? Maybe slow down the repeat cycle? Or is this strictly a issue with how the actual event drivers or the buffers work and would need changing to that on the host side? In my mind it seams fairly straightforward in just forwarding these events to the VM.

Would it be different if the keyboard was using the PS/2 versus the USB interface on the guest? I have a USB controller added for the guest but the keyboard and mouse are on PS/2 interfaces.

A second thought. What if you made the keyboard and mouse USB only, then on the guest, make sure the USB controller is using Message Signal-Based interrupts. On Windows, the controller was set to the old style Line-Based. The slow downs could be caused by a lake in speed with he interrupts and USB polling speed.

Would you be able to tell me how to make the keyboard/mouse USB only and enable repeat keys, so I can investigate this option? If it works like this then a good set of instructions will need to be done to enable all this and solve an issue. :-) Also, I would need to know the cases where the slow downs happen to test.

What do you think?

-Jon

Support used to be there, but the constant flow of key repeat events in
case you hold down a key longer (like you do with shift or ctrl in some
games) made things unstable so I turned that off.

The mouse emulated by qemu has only three buttons.

cheers,
