Subject: [Qemu-devel] Kernel mode VGAs?
Date: Tue, 14 Feb 2012 08:12:25 +0100 (CET) [thread overview]
Message-ID: <alpine.LFD.2.02.1202140808540.21607@bbs.intern> (raw)
Hello,
Current QEMU-KVM VGA implementation have the following problem with legacy
OS (e.g. DOS with INT10h calls): Performance is low on accessing A000:0
page and doing bank switching at the 64k page.
Would a kernel mode VGA solve these problems?
How complicated is it?
Is it possible to have only some parts in kernel mode?
Any further ideas or suggestions?
Thnx.
Ciao,
Gerhard
