[Qemu-devel] GSoC 2015 (Mac OS 9 support) report, week 10

[Alexander Graf]

[Done]
  - Update project log (6.17)
  - Debug OpenBIOS ADB issues since agraf's 26a9dfe patch

[This Week]
  - Update project page (7.7)
  - Fix cuda_adb_req() to expect a 3-byte header instead of a 2-byte one
    - This has a preliminary fix but will need some backwards-compatibility
      changes. Initial patch will go out in the next few days.
  - Try to fix ADB mouse issues
  - Install macbugs on hard disk image via MOL

[Next Week]
  - Enable debugging in MOL
    - The installation is now broken after a failed make. Tried reinstalling
      from Zypper but it couldn't find the config files -- do they have to be
      added manually?
    - The config files are at a different location when you compile manually,
      but I don't remember where everything was :). Just run mol with strace,
      it will tell you where it's looking for things. The current ones should
      be somewhere in /etc.

[Long Term]
  - Continue updating project log
  - Create and send patches
    - [ ] Patch: Boot script loader
    - [ ] ROM node
  - Patch: RTAS node
    - Patch has been sent in and is awaiting review.

For my port of qemu to Quadra 800 emulation, I've split ADB in 3 parts
(controller, mouse, keyboard).  I think I've corrected some issues...

https://github.com/vivier/qemu-m68k/tree/q800-v2.3.0/hw/input

Could you CC: me on patches for this part ?

If you want, I can also send my patches... but not sure it doesn't break
ppc...

That particular issue is fixed - we treat unknown packets as "set device 
address" which is a really dumb default ;).

The main change we needed for ADB to work properly was to switch from a 
2-byte header to a 3-byte header. There will be patches for that too and 
I'm happy to ensure you're on CC when they go out :). Unless you want to 
beat us to it of course...

No, with the experience, I learned to let the student to do my job :) .

I will test them on Quadra 800 to see if it breaks something...

Thanks,
