Note: This page is not actively updated anymore, and thus is not really representative of what has been done and what is remaining. See the TODO-list instead, which is up-to-date.
nouveau : required functionality
Here is the feature matrix for the functionality we need :
"TODO" means we need to figure out that feature and document it (basically find out which code is sent to the card for this feature).
"WIP" means it's in progress.
"N/A" means we don't need it.
"DONE" means... well that it's reversed but not implemented.
"IMP" means... well that it's already fully reversed and implemented.
