In Topic: Mavericks kernel testing on AMD (formerly Mountain Lion kernel testing on AMD)

for developers:

libbeauty

libbeauty is a very advanced open source tool that has an initial aim:
"Given an input .o file, it can create a .c file that compiles and has the same function as the original .o file. This will later expand to handling binary files."

hi

right now i have no time to perform test like in osx-10.7 kernel days. but sometimes i take a look on whats going on, really impressive!

 

i was wondering about the idea of looking at other BSD kernels sources that already runs on amd cpus, how do they implement tlb caches and all that stuff for amd hardware, since it is already done.

the hard part would be implementing propertly arbitrary opcode emulation (and then specific opcode emulation) this requires knowledge, but seems to be a good programming exercise.

 

i hope not to be wrong, that this ideas are useful. please dont feel bad to correct if im wrong.

i will be back to testing when situation gets better...

 

peace!

I have an idea (and going to implement myself in my own testing): to organize things better, what about a standardized report form?

 

I was thinking about this:

 

- Kernel name and revision;

- Boots (y/n): If doesn't, a screenshot of the verbose output is mandatory;

- Panics (y/n): same as above;

- Artifacts: self-explanatory. Usually screenshots would be inaccurate, so a pic taken with a tablet/mobile phone would do;

- Glitches: programs that malfunction etc: detailed descriptions and screenshots if they apply;

- Crashes: crash reports;

- Miscellaneous: any further info you should add.

 

I think that could help devs to pinpoint issues better.

 

All the best!

the osx kernel port to amd project should be in github or similar, with proper bug track list, source changes, and all that y think everything will be better organized

In Topic: GRUB2 -> Chameleon

the right way.. is chameleon call grub2 in the linux partition
in GUID

this solution is for when chameleon cannot detect grub2

i think it can be useful information for those who has a linux as backup system installed on their hard drive.

GRUB2 will be the main boot loader. it will chain load into Chameleon!

by default, GRUB2 does not detects propertly OSX86. this is a little fix for grub2.
