From 31610434bc3523c0b01a10917a1185096a03c4c8 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Mon, 22 Oct 2007 11:03:39 +1000 Subject: Virtio console driver This is an hvc-based virtio console driver. It's suboptimal becuase hvc expects to have raw access to interrupts and virtio doesn't assume that, so it currently polls. There are two solutions: expose hvc's "kick" interface, or wean off hvc.
