Hi, I'm trying to route all the physical interrupts to the guest domain rather than being trapped in the Xen. I would like to know what is the right way to do that?
I know that HCR_IMO bit in the HCR_EL2 register is supposed to be for routing the interrupts to the guest (Routing to EL1 instead of EL2). link to the datasheet: http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0500d/CIHJHAAG.html So, I have tried doing the following in the leave_hypervisor_tail. I run a simple hypercall and do the following lines before return (which is I guess the last point of exit to the guest from hypervisor): --------------------- *current->arch.hcr_el2 &= ~HCR_IMO;* *WRITE_SYSREG(current->arch.hcr_el2, HCR_EL2);* *isb();* *----------------------* *It looks like to be doing it right for all the vcpus but gets stuck after return from leave_hypervisor_tail for the last vcpu.* Any help is appreciated, Thanks, -- Saeed Mirzamohammadi PhD Student Department of Computer Science University of California, Irvine Irvine, CA 92617 sa...@uci.edu <smirz...@uci.edu> http://www.ics.uci.edu/~saeed/ <http://www.ics.uci.edu/~smirzamo/>
