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