RE: [Xen-devel] Injecting physical IRQ (pirq) into hvm guest

["Dong, Eddie" <eddie.dong@xxxxxxxxx>]

Guess you are trying direct hardware assignment for HVM.

How do you translate the vetor to IRQ line?

If the physical IRQ you received is a PCI IRQ, then the guest PIR may be different with machine PIR.

 

thanks, eddie

Subject: [Xen-devel] Injecting physical IRQ (pirq) into hvm guest

Hi Folks,
I want to inject an interrupt into the hvm guest based 
on a physical IRQ (pirq) I receive in Xen hypervisor. I tried calling 
pic_set_irq() function in ../xen/arch/x86/i8259.c but that didn't 
work.

Could someone please help me with this? 

Thanks,
Sanjay
