Subject: [Qemu-devel] [PULL 5/6] xhci: relax link check
Date: Fri, 12 May 2017 14:21:57 +0200 [thread overview]
Message-ID: <20170512122158.32032-6-kraxel@redhat.com> (raw)
In-Reply-To: <20170512122158.32032-1-kraxel@redhat.com>
From: Ladi Prosek <lprosek@redhat.com>
The strict td link limit added by commit "05f43d4 xhci: limit the
number of link trbs we are willing to process" causes problems with
Windows guests. Let's raise the limit.
This change is analogous to:
commit ab6b1105a2259c7072905887f71caa850ce63190
