Subject: x86: Exception handling via task gates broken
Date: Mon, 22 Mar 2010 14:34:45 +0100 [thread overview]
Message-ID: <4BA771F5.5070401@siemens.com> (raw)
Hi,
when switching an x86 hardware task because of some exception, KVM does
not push potential error codes on the stack of the handler task. I guess
not many OSes make use of this slow feature - we found one :). Does
anyone happen to have a fix on his agenda? Otherwise I will look into
this (next week).
