Hi all!
Previous week I started to work on SMAP for amd64 and i386. For amd64
many parts are in good state. The codes currently are only compile
tested, at next week I create a VM, and create run-time tests. For
i386 started the work on yesterday.
All of my status can be found on my wiki page.
What's done, but not tested in this week:
* {amd64,i386} trap handler
* amd64 initialization
* {amd64,i386} identification
* {amd64,i386} exceptions
* amd64 pmap changes
* amd64 support.S changes
* amd64 ia32 compat exceptions
* i386 ddb extension
At next week I plan to finish all of amd64 things, and most of i386
things, and begin to test; start to design a proper way to create
kpatch and/or ifunc like things.
