[PATCH 0/5] Enable bus master support for rtl8139 network cards on Apple PPC machines
by Mark Cave-Ayland 07 Aug '16

07 Aug '16

This patchset is loosely based on earlier work by BALATON Zoltan <balaton(a)eik.bme.hu> and provides basic infrastructure to allow OpenBIOS to enable PCI device bus mastering. Following on from discussions on the QEMU mailing list, it seems that Apple's OF enables bus mastering for some PCI devices by default, and as a result some buggy drivers forget to explicitly enable it and hence these devices fail under QEMU's emulation. The first 3 patches add the basic support routines while the last 2 patches enable bus mastering for the rtl8139 card on Apple PPC machines which is required for OS X and MorphOS.

[PATCH] ppc: fix ESCC reg properties
by Hervé Poussineau 30 Mar '16

30 Mar '16

I/O offsets were wrong in legacy mode and some were missing in non-legacy mode. This fixes serial port detection in NetBSD, which was ignoring it. This also partly fixes MacOS 9.2, which relies on them to initialize OpenTransport.

Google Summer of Code 2016: Make Mac OS 9 boot successfully with all Apple extensions
by Programmingkid 17 Mar '16

17 Mar '16

=== TITLE === Make all versions of Mac OS 9 boot successfully in QEMU with all Apple extensions '''Summary:''' Short description of the project Mac OS 9.2 does boot in QEMU without extensions, but certain extensions that ship with Mac OS 9.2 need to be disabled or else they will cause booting to fail. We need any issues with OpenBIOS and QEMU fixed so that Mac OS 9 will boot successfully in QEMU. Detailed description of the project. These are the known extensions that cause Mac OS 9.2 to crash: • Apple Audio Extension • Apple Enet • Multiprocessing folder • Open Transport aslm modules • Text Encoding Converter Without them some applications running in Mac OS 9 are severely limited or simply refuse to run. '''Links:''' http://wiki.qemu.org/PowerPC http://www.emaculation.com/forum/viewtopic.php?f=34&t=7047&sid=3044078243e3… '''Details:''' * Skill level: advanced * Language: C, PowerPC assembly * Mentor: None currently * Suggested by: John Arbuckle programmingkidx(a)gmail.com

Just to go past the 'switch-arch' stage, I had to rename sparc32_config.xml to sparc_config.xml. The build system for sparc might need a little fixing.
