Depending on how the alloc/free behaviour is in the code to be ported, a
simple provisional
allocator could be added (temporarily), i.e. create a larger area of
contiguous memory and hand out
pieces of it.
So, I need to have a provision which will allocate one page at a time (or
multiple pages) and then
give away segments of the page to each kmalloc call.
You can't allocate one page at a time for this. You need to allocate one big
chunk of contiguous memory.
If you allocate only one page at a time, you can't guarantee that they are
contiguous. Maybe someone allocated a page just next to yours.
Having something like that will ease the process a lot in the coming months,
but will be some work
for now. Is that what everyone thinks would be the way to go?
I think writing code to get DRM to run on Haiku is exactly what you should be
doing during the summer? It's expected that it starts with low level code like
this, and then build up over time to more high level problems.
