hi @Julien,
Got it. TVM has two runtimes: a C++ runtime (used when OS present and referenced in many of our tutorials) and a C runtime (used when OS not present; referenced in our microTVM tutorials). Support for this arrangement isn't complete yet but would fall under microTVM. See the [µTVM M2 roadmap](https://discuss.tvm.apache.org/t/tvm-microtvm-m2-roadmap/8821) item 11. However, people have used TVM with accelerators and on ARM microcontrollers, so there are essentially two parts to this: 1. Get the TVM C runtime working on RISC-V. I believe @dream-math was working on this. 2. Implement your accelerator in TVM using [Bring-Your-Own-Codegen](https://tvm.apache.org/2020/07/15/how-to-bring-your-own-codegen-to-tvm). There are also some additional work items which we would like to get to at some point to make this process more streamlined and implement runtime optimization such as async execution. However, those aren't strictly required to get things working. Let me know if this answers your questions!
