HEAP #7

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
The heap is in flux. We did not leave the code from FPOS in a stable state.

HEAP is normally USERMODE memory management of a linked list(stacked chunks of 
choclate instead of a stack of papers in order).Hence the C is a bit messy.

HEAP must be initialized when the papging unit(VMM) prepares to flip the paging 
bit.From then on, HEAP automagically allocated and frees ram by variable, 
paging unit/heap unit work as one to allocate/free by page(4K chunk) as the OS 
requires it.

A lot of units here on out require RAM(therfore HEAP) to function. Once this 
unit is fixed, we can move on.

I have reworked some of BrokenThorn examples from C at the moment, I am merging 
in FPOS code and parts from the FPC RTL.Code is currently UNSTABLE.
