From 8cbad670cecaa88cc48115233bc4bc290dadd782 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Herv=C3=A9=20Poussineau?= Date: Tue, 22 Apr 2014 23:00:31 +0200 Subject: [PATCH] i8259: don't abort when trying to use level sensitive irqs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is a guest-triggerable error, as seen when using Xenix 2.3.4. Replace hw_error by LOG_UNIMPL, so that guests can continue. With this patch, I can install and use Xenix 2.3.4a without any problem. I can also start installation of Xenix 2.3.4q, but it fails due to not finding an hard disk. Signed-off-by: Hervé Poussineau Acked-by: Michael S. Tsirkin Signed-off-by: Michael S.
