I am not sure if I understood your comment correctly. Currently, qemu
has a check in `riscv_cpu_do_interrupt` to allow semihosting calls
only in S and M modes. This prevents semihosting calls from U mode.
This patch changes the default behavior of checking `>= PRV_S` for
semihosting and instead replaces it with the usage of
ebreak{m,s,u,vs,vu} properties to allow the user to configure what
modes should allow semihosting calls when `-semihosting` argument is
selected.
Why do you need such fine-grained control? What is the use-case?
