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

["Yu, Ke" <ke.yu@xxxxxxxxx>]

To inject a irq into HVM guest, should call pic_set_irq twice like this:
pic_set_irq(pic, irq, 0);
pic_set_irq(pic, irq, 1);

Calling it one time won't work. Is it the reason for your case?

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
