Trying to make systemTracer write a CogImage

Ok, I'm writing the image header as with the extra words.  But my image is kind of not living.  It seems the Display is not waking up.

When I open my new image with a cog vm, I get an image that does not break, but comes up with a window in black. I sent a SIGUSR1 to the vm Process and get the following.

Most recent primitives
relinquishProcessorForMicroseconds:
relinquishProcessorForMicroseconds:
...
(more relinquishProcessorForMicroseconds:)


Now, looking at the primitives called, It seems the idle process is living but not giving any place to the other processes...  any ideas?  Does cog do something different with processes at system startup?

Of course not :)  It's a Squeak VM with a JIT.

 

Thanks!

Ok, I've managed to get the cause of the process failing :).

I'm having a primitive failure in

VirtualMachine class>setGCBiasToGrowGCLimit: 2002796048: a(n) VirtualMachine class

when trying to startup the vm, and therefore the ui process is never set up :/.  But I do not know why it should be failing :(.  I'm still debugging.

And this is because I have to put in 0 the index of the cache in named primitives literal :).

Still not working, but better than yesterday :).

And now it works! :D  I was setting wrongly the endiannes flag in the vm header, and the floats were not well read.

Next step, polish and publish new SystemTracer :).

Brilliant!  Well done for pushing through.  Now you're the expert!!

The good thing is that he is learning a lot about the VM but at the same time delivering something useful for the community.
