Hi Andrew,
Just noticed the RISC-V 32-bit kvm selftests was not supported currently. Even though I tried to remove the below check for 32-bit, there were still many warning and error messages during compiling. It seems 32-bit KVM selftests was not supported either for ARM/x86. Do we have a plan to support it on risc-v?
Regards, Haibo
