Are there any reverse engineering efforts being made for SGX hardware, similar to Nouveau?

Yes!

The 6410 contains Samsung's own GPU, which is derived from the old AMD embedded division that Samsung bought. It has nothing to do with SGX, despite what Luke Leighton might try to have you believe.

It was Qualcomm that bought the Imageon line from AMD(which they use in their Snapdragon line):

I'm sorry, you're right. The Samsung one appears to be from scratch.

I've compared lists of supported extensions on PowerVR and Samsung, they look similar.

I have not yet looked in details but so far it looks like that Samsung's chip is just PowerVR IP-core with some custom bits.

Samsung also produce chips with PowerVR. The 6410 isn't one of them.

yes that was a mistake on my part - the S3C6410 has "FIMD" which samsung would have bought in (they *never* make anything of their own). there are two teams in samsung: their designs overlap, so one team comes out with a SoC whilst the other one is still working on the next one. the S5PC100 (800mhz) had the same "FIMD" 3D engine, but the S5PC110 (1ghz) had that FIMD engine ripped out, to be replaced with a PowerVR SGX engine. exactly why is anybody's guess. but yes, i made the post to which you're referring *before* i had this information.

There is also FSF High Priority Project

I hope those two are not duplicating each other.
