[Xen-devel] VLAPIC and Event channel relationship or how to map PIRQ to HVM guest

[Dmitry Rockosov <rockosov@xxxxxxxxx>]

Hello guys,

Could someone help me with VLAPIC and Event channel relationship? I can't find any good design overview for it.

Are they compatible things or not?

Actually I want to map any PIRQ to HVM guest (for example keyboard), and use VLAPIC to deliver virtual interrupt to HVM guest.

But seems like all interrupts from keyboard are working through the Event Channel Upcall Interrupt with vector 243.

Please, help me or point any useful documentation.

Thank you!

Best Regards,

Rockosov Dmitry
