Simulating seL4 with Renode

Note, this repository is a work-in-progress

The purpose of this repository is to give examples of using the Renode simulator with the seL4 microkernel. This is primarily done by simulating the seL4 test suite, seL4test.

The hope is the work put into these examples will help people using seL4 evaluate whether Renode is appropriate for them.

Note that if you want to run these examples I recommend that you build Renode from source.

RISC-V

Caveats

Test PAGEFAULT0005 does not work, unclear whether the test is wrong or Renode is at this moment. I need to look into it!

Platforms

QEMU RISC-V virt

seL4 currently supports the virtual RISC-V platform that QEMU provides, we can emulate this system using Renode as well:

renode -e "start @qemu-riscv-virt-sel4test.resc" --console

SiFive HiFive Unleashed

renode -e "start @hifive-unleashed-sel4test.resc" --console

Looks like hart switching does not work on Renode (at least from what I can tell) so when the OpenSBI booting hart ID does not match seL4's CONFIG_FIRST_HART_ID, the whole system halts without getting past the hart switching to seL4 and seL4test unfortunately.

Pine64 Star64

TODO

ARM

QEMU ARM virt

renode -e "start @cortex-a53-sel4test.resc" --console

For AArch64 it looks like Renode can successfully start and run sel4test, the main problem right now is that the simulation is extremely slow.
