Subject: [Qemu-devel] memory usage and ioports
Date: Mon, 19 Nov 2007 15:20:16 +0000 [thread overview]
Message-ID: <20071119152016.GE6331@implementation.uk.xensource.com> (raw)
Hi,
Qemu currently uses 6 65k tables of pointers for handling ioports, which
makes 3MB on 64bit machines. There's a comment that says "XXX: use a two
level table to limit memory usage". But wouldn't it be more simple and
effective to just allocate them through mmap() and when a NULL pointer
is read, call the default handlers?
Samuel
