Hallo Alexander,
Now I think that it is closer to what I need for golang runtime, at least it works here. Could you take a look?
I just ported current set of patches to 20.11. please, take a look at https://github.com/tor-m6/genode.git branch 20.11 main implementation of mmap part temporary in 1 file and 1 patch anon_mmap.cchttp://anon_mmap.cc/ from https://github.com/tor-m6/genode/commit/cf79a564e1b004fef5660e84d01d6c290674... and genode files minor modifications https://github.com/tor-m6/genode/commit/41b57fd06516c9b33b4b06e1f91cb134a3da...
I'm going to take a look at your changes and probably will get back to you with some Golang related questions in general (it might take one or two days).
Regards Josef
