| Thread-topic: | [PATCH] Fix context switch to idle domain |
Don't change ivt table and vhpt table when switching to idle domain, or else we have to restore region registers too. Actually this change can also improve performance a bit, since idle domain can inherit most of prev's environment. Without this change, we kept seeing vhpt fault when running host SMP with multiple domains. Signed-off-by Kevin Tian <kevin.tian@xxxxxxxxx> Thanks, Kevin
