I hope Ryan gets a developers kit for Panther soon and comes out with XPF 3.X before Fall. New Macs shiiping in August |

I think you're right that this probably won't affect my ability to get the kernel stats. Interesting thing is, Apple hasn't posted the source for Darwin 7's top command. It was in the system_cmds tarball for Darwin 6. But I did find source code for the vm_stat command which looks pretty similar to the way top accessed the stats in Darwin 6. I'll try vm_stat's method in place of tops' method to find out if I can get the same results. |

The change I'm thinking of is mostly that you can't access physical memory naively in the kernel anymore--you have to actually map it in (i.e. use IOMemoryDescriptor properly). There are some places in my drivers where I don't do this, so it will need to get fixed. I don't think this specific issue will affect what you're doing (but there may be others). |

Ryan, Could you elaborate just a little bit on the Panther memory management changes? I've finally got around to start coding up a GUI version of the ram testing utility "memtest" and I had to borrow some code from the Darwin "top" command to determine how much physical ram is free for testing. Since this info is obtained from the kernel, I'm wondering if any coding changes will be needed. Guess I'll go up to the Darwin page and grab the 7.0 top source as well. Just looking for a heads up at this point. Tony |

I've got the developer preview now in fact--I'm at WWDC this week. And I'll get Panther working before it's released if it kills me :-) Let me say that Panther is pretty impressive in a variety of ways. The Exposé feature, in particular, is extremely well implemented. And the new Finder is nice, though it takes a little getting used to. There is one significant change that Panther makes to memory management in the kernel that is going to require me to do some work on the kernel extensions which come with XPostFacto. But that by itself shouldn't be too difficult--the issue is well understood. Once that is done, we'll see if there are any other problems hanging around. But a first glance at the way Panther is laid out does not reveal any obvious problems. |

I agree. The new machines are very compelling, more compelling than the current crop of G4s. I also like the new box's design although I have some concerns about the amount of dust that will collect inside due to all the holes. Hopefully, there are more holes to allow dust to just freely flow through rather than stick around inside. |

My PPC 7600/NewerTechG4-350/RadeonMacEdition runs OS X 10.2.6 real nice, with the help of XPostFacto. But I am sure that no matter what Ryan comes up with, the old faithful is not going to do justice to Panther. So, 7600 to one side, but close at hand for doing things it does well, and G5 right smack dab in front - woohoo !! |
