From 934bf65354227981df15bbc755d33f4ba3443ff2 Mon Sep 17 00:00:00 2001 From: Matt Gingell Date: Mon, 16 Nov 2015 15:26:05 -0800 Subject: [PATCH] KVM: x86: set KVM_REQ_EVENT on local interrupt request from user space Set KVM_REQ_EVENT when a PIC in user space injects a local interrupt. Currently a request is only made when neither the PIC nor the APIC is in the kernel, which is not sufficient in the split IRQ chip case. This addresses a problem in QEMU where interrupts are delayed until another path invokes the event loop.
