Yes, from my own perspective I understand this well. :-) > > One of the patches made the stated CI20 support actually work, thanks to > > Sarah's guidance, so it must surely be of interest to more than just me. > > The > > You're talking about the cache instruction issue? Yes (ci20-rdhwr.diff). I was also potentially interested in supporting other instructions that related SoCs do not support, at least where those do not support floating point instructions natively, and where L4Re/Fiasco.OC might not be buildable using "soft float" instructions (advice welcome!), but this is a different topic altogether (and one that I am not likely to explore in the near future). > > other patches attempted to support gcc instead of the vendor compiler, > > which I would also think would be desirable (especially given the > > corporate "pass the parcel" game going on with the vendor in question at > > the moment). > > Well, then lets discuss those changes. Thinking back, there was some uncertainty about whether it was appropriate to generate position-independent code when building Fiasco.OC, where I had introduced initialisation of t9 so that global offset table lookups functioned correctly (ci20-gcc-cpload.diff). There was also a trivial patch changing the compiler prefix for Debian (ci20-gcc-debian.diff). You also mentioned the following patch when I experienced problems that had something to do with variable or member initialisation: http://os.inf.tu-dresden.de/pipermail/l4-hackers/2017/008005.html Was this merged upstream in the end? I was rebasing my own large patch against an updated upstream repository, but other matters took priority and I haven't looked at it again. I had been trying to write a few device drivers for the CI20, specifically for GPIO, CPM and I2C, with the latter being unreliable and rather annoying.
