If you badge the SMC cap, the kernel will only allow smc calls with x0 matching the badge value. In the smc calling convention this is the function ID. On Fri, 7 Mar 2025 at 12:19 pm, Ivan Velickovic via Devel <devel@sel4.systems> wrote:

The kernel implementation allows for fine-grained control over specifically which SMC calls are allowed by a PD, however, I don't think Microkit has implemented that granularity yet. That means you can either forward all SMC calls or none of them.
Can you expand on this? I do not see anything in the seL4 manual or the implementation that suggests any granularity with SMC forwarding.
