10.6 Snow Leopard PowerPC Development

[ChrisCharman]

@educovas Quick update:

I have restored internet functionality without depending on an additional third party DNS to TCP application. As i suspected previously, there is an issue with Kerboros. If you update the system using MIT Kerboros Extras it fixes the issue that is blocking network connectivity.

Edit: I have only tested this on a PowerBook G4 and AGP Powermac G5 using Wifi. This version of 10.6.8 may also contain other modifications that have contributed to the fix.

This is amazing news. Thank you for your work on this!

If you could make an installable pkg when you have time for it, that would be very helpful.

I will include in an installer update package along with any other tested AOSP binaries as soon as i can. In the meantime a link to the MIT Kerboros Extras installer package has been added to the WikiPost. If someone else could download and verify that this is indeed what fixed internet connectivity that would be helpful, otherwise i’ll have to see what else i’ve updated recently.

That's awesome! I'll see if I can get it to work here tomorrow.

 

[educovas]

Installed the package here and it did not work, unfortunately. I think it might have been something else that fixed the problem.

 

[educovas]

I think I accidentally found something interesting about the problem with ejecting USB drives. It seems to happen only on drives formatted with the apple partition map scheme, GPT and MBR don't have the problem and can be ejected normally.

Ok but it didn't work until after the Kerboros update - i did also replace all cups binaries (including /sbin) as was done with 10A190 previously. Any other changes will need to be checked later as i'm at work.

I have no idea how kerberos works and what it does so I'll wait for someone else to test.

The current image already includes cups binaries compiled from source so I don't think that helped with this problem.

I’m using alpha 3 still and updated cups binaries myself

Yeah i updated the wiki with the new link and details a while back, i just haven’t had a chance to download it yet.

This is where you got internet working?

 

[ChrisCharman]

This is where you got internet working?

Just recounting most recent changes to the system aside from Kerboros Extras.

We replaced cups on 10A190 if you recall which fixed some bugs which included enabling software update to run.

Kerboros is used for network authentication and there are issues with the included version in the image, it’s possible that a combination of both of these fixed network connectivity.

It’s possible I’ve replaced other files as well as i was building Apple Open Source Projects on the PowerBook a while back but i’ll have to check what was built as it’s all on an external drive.

I'll try to replace those files. It would be good to know what you did with kerberos other than installing that package to see if I can get working internet.

No manual Kerboros configuration was necessary. The installer package handles everything.

 

[educovas]

Oh, ok. We'll have to try all of the changes you made to see what fixes the problem then.

 

[ChrisCharman]

I have now downloaded, modified and updated the last image (alpha 4) and replicated my previous fix (with alpha 3). I have also added a few other updates.

The new alpha 5 image has the following changes:

1. utDNS and the launchdaemon have been removed
2. A number of missed cups binaries and other executables that were still intel only have been replaced with the ones from 10.5.8 in /usr, /sbin, /usr/bin, /usr/sbin, /usr/libexec and /usr/share
3. /usr/include folder restored
4. Various unix permissions errors in kexts and base system binaries corrected
5. Kerboros Extras and configuration files pre-installed as default
6. Intel Kerboros Apps replaced with 10.5.8 versions
7. AppleScript Apps in CoreServices replaced with PowerPC versions
8. System Image size reduced by removing all architectures other than PowerPC from system binaries
9. TextEdit app updated
10. Airport Utility app updated
11. Front Row app updated
12. ATi Radeon drivers updated to include ROM extender
13. NTFS Kext replaced to rectify missing copyright string issue
14. IOAHCIFamily and AppleAHCI kexts replaced with more recent versions from 10.5.8

I’ve also accidentally left interwebppc in the applications folder, and a few user preferences.

*DHCP should function correctly. In order to get internet connection, the IP address, subnet mask and router address might still need to be entered into network preferences on some systems, but otherwise should auto configure. Cloudflare 1.1.1.1, 1.0.0.1 and Google 8.8.8.8 DNS servers can also be added via the network prefpane in System Preferences if required.

This image should continue to work with all GPUs that were supported in 10.5.8, including Nvidia.

To avoid having too many different disk images floating around the web and reduce bandwidth usage for the end user, we will be moving to delta updates provided as packages soon, now that internet access is resolved in 10.6.8 PowerPC.

This image will be made available for download and linked in the wikipost once uploaded.

 

[Jazzzny]

Can you not strip the system binaries? This only makes development harder, as it is no longer possible to easily compare binaries with stock 10.6 to see if they are modifed.

Additionally, I believe that development cannot be sustainably done this way. If your goal is to reduce the number of images floating around, then there should be a centralized way (i.e. master AFP server) where developers can update files, and from which images automatically get built from). Otherwise, development will eventually sprawl into a mess of different images based on different images.

Both excellent points

@Jazzzny A large number of system binaries are already ppc only at this point, but it does make sense to not strip the disk images uploaded for sharing and testing - i will upload a different image to the one previously prepared.

I have been thinking about that a lot in recent weeks, and have just registered a domain and hosting. I’m planning to have a base .dmg hosted there for remote restores (if people would want this) but primarily as a repository for all of the built replacement parts for people to download.

Delta updates can then be provided via update packages, once we have tested and verified on multiple systems.

Please replace the ntfs kext with the fixed one before uploading a new image.

@educovas Good shout! I’d forgotten about that one, i’ll add to the re-image before uploading.

By the way, word of caution to anybody testing on a PowerBook, at least on the machine i was using earlier today it seems that the thermal power management and fan control are not quite right currently. After spending quite some time booted into 10.6.8 images, upon rebooting there was a rapid and noticeable increase in fan speed using 10.5.8 to cool the system down. This was sustained for quite a while.

Another power management related issue is upon shutdown from 10.6.8 followed by immediate boot the system will not power on (occurred on 2 x separate PowerBooks). I believed it to be an issue with the first machine until realising that a cold boot after draining all power resolved the issue until the next shutdown from 10.6.8.

I’ll extend the table and add to the issues in the wiki.

 

[saxfun]

I have to watch carefully the Temps on my a1138 PB then. I Never Had Any Problems with shutdown and rebooting again.

 

[barracuda156]

@ChrisCharman @educovas Please find some way to have updated OpenGL stuff for NVidia systems too (whether as an image, a package or at least a set of files to replace against the delta5).

I can mirror that on macos-powerpc.org too then.

P. S. If you will have space, I encourage mirroring pre-built software from packages there, and then your server will be included into PPCPorts config. It will be better if at least two servers have everything, so that if one is down, there is a backup.

That’s a good idea @barracuda156. I’ll let you know when the site is online.
