[OLPC-devel] Weekly work summary [7/12]

[Nitin Gupta]

Hi,

This is work done this week:

-- Understand git enough so I don't mess up repo very often :)
-- Real work: Compressed caching:

I'm having a _very_ hard time fixing all things related to vswap. 
Especially, storing and restoring pages that have multiple PTEs pointing 
to them. Many code paths assume there must be block device associated 
with a swap and they OOPS when they deal with vswap. Also, there's a 
problem that vswap once full, can't be reused. Fixing this is taking so 
much time (and is not yet fixed).

So, where is project now?
-- Working on to make storing and restoring anon pages to/from vswap 
stable. This is base of ccaching for anon pages.
-- I know handling filesystem backed pages will have additional issues 
but had no time looking at them for now.

Fixing vswap issues, as above, are taking longer than expected and are 
still not over. So, I don't know what to expect next week.

Once this goes stable, I'll integrate compression structure with it to 
have a functional ccaching for anon pages.

See you next Sunday...hopefully with some good code :)

Cheers,
Nitin Gupta
