On the TC front, more or less what knc1 said, except I'd stay away from multilib/interwork TC, unless you want a wall with an embossed version of your head on it ^^. And the things I mentioned/are commented in my x-tc script if you're using something recent and targetting the K2/3 (kill gcc's ssp: -fno-stack-protector in CFLAGS & CXXFLAGS, kill glibc's fortify: -U_FORTIFY_SOURCE in CPPFLAGS).

Yep those are the flags I managed to glean so far.

There was some talk on a thread somewhere - that I fail to find right now as per - that did have a nice list of compiler optimisations too (with tests for why they were decent choices) they would be a nice addition to a) this thread and b) the project effort as a whole. I'll see if I can find it. I think GM was chatting on it.

At the end of the day the type of people I envision - "Having a go" - at porting something will thank us for ensuring that the maximum amount of stuff-that-can-go-wrong has at least be thought about, documented, or covered. Thinking about it that's exactly what I would like too!

So I will pretty much go with the consensus on best TC - knc has some string and clear ideas about what the possible benefits of such an endeavour could be so I defer to him on the final say on these matters. This kind of input is invaluable in making good decisions, thank you.

So GM recommended TC DL (thanks GM, I really have to get my knowledge of this stuff sorted) Let's see how she goes.

EDIT:

[root@kindle fs]# strace -o /mnt/us/modules/gm-2008-CS.tc insmod /mnt/us/modules/smbfs.ko
insmod: error inserting '/mnt/us/modules/smbfs.ko': -1 Unknown symbol in module

Fail

Hmm Dunno.

I'll try again tomorrow with knc's recommendation when it sufaces : )
see how we go.
