[Dri-devel] Updated texmem-0-0-2 design document (03-Mar-03)

[Ian R. <id...@us...>]

Not too many updates this time.

There are a few issues that I really want to discuss & work out before 
any coding begins.

1. Felix Kuhling asked, basically, how does a process manage the memory 
blocks that it has claimed.  The issue is that each process "owns" a set 
of memory_blocks that may or may not be full.  How do we manage 
allocations within those blocks?  A related issue is with assigning 
block IDs.  How would we handle a situation where we could allocate an 
object that spans the end of a memory_block with on ID value and the 
start of another memory_block with a different ID value?

2. Issues 3.1 & 3.2.  Basically, what extra data needs to be tracked in 
the memory_block so that we can make decide which blocks to reclaim?

3. Issue 3.11.  Where should the device independent, client-side code 
live?  lib/GL/dri and lib/GL/mesa/src/drv/common are two candidates.

I think if we can resolve these issues, we can reasonably start doing 
some coding.  Thoughts?
