[Qemu-devel] [patch] TOC support for raw cdrom block devices

[Josh Elsasser]

The current raw block drvice code fakes a TOC with one track covering
the entire disc.  With this patch it attempts to read the TOC from a
cdrom device and make that information available to the ide driver
when the guest issues an ATAPI READ TOC/PMA/ATIP type 0 (read TOC)
command.

There is only support for reading the TOC on the BSDs, MacOS X, and
Linux, Win32 and other OSes will still fake one large data track.  All
tracks are reported as data, no attempt was made to support audio
tracks.  The ATAPI READ TOC/PMA/ATIP type 2 (read full TOC) command is
unchanged, I did not have a way of testing it.

The purpose of this patch, in case anyone was wondering, was to get
the BeOS R5 CD booting in qemu.
