From: Mark Cave-Ayland
Subject: [Qemu-ppc] [PATCH 00/13] Mac OS 9 compatibility improvements (upstream rework)
Date: Fri, 23 Oct 2015 14:56:25 +0100

This is a rework of Cormac O'Brien's GSoC project to try and boot MacOS 9 under
QEMU, the original version of which was posted to the qemu-devel list at the
end of August 

The patchset consisted of some simple patches from Alex and then a large set of
CUDA changes supplied as a single patch which were the result of Cormac 
MOL with Alex's help to try and further the boot process.

In their previous form, the patches were unsuitable for applying upstream since
while they furthered MacOS 9 boot, they also caused a couple of major 
such as breaking the mouse and causing Darwin/OS X boot to panic on startup.

This reworked patchset fixes these regressions, includes some other clean-ups 
and more importantly now passes all of my OpenBIOS image boot tests with an 
OpenBIOS binary from SVN trunk (separate pull request to be sent shortly).
Whilst OpenBIOS still needs one additional patch to run the MacOS 9 bootloader,
I've uploaded a pre-compiled binary to 
https://www.ilande.co.uk/tmp/openbios-ppc for people interested in testing the 
new MacOS 9 functionality.

Apologies for the delay in sending this out on-list, however due to recent
circumstances I've been without a reliable broadband connection for a couple
of weeks. However given that this is mostly a rework of the previous patchset 
and looks good in testing here, I'd definitely like it to be considered for
application during soft freeze.
