TEST_GEN_PROGS_loongarch = $(TEST_GEN_PROGS_COMMON) is missing.
BTW irqfd_test in TEST_GEN_PROGS_COMMON fails to run on LoongArch, does this
test case pass to run on Riscv?
It appears to. It outputs the vm mode created and then exits with a zero
exit code.
Here is output of irqfd test on LoongArch
[root@kvm-131 kvm]# ./irqfd_test

KVM_IRQFD failed, rc: -1 errno: 11 (Resource temporarily unavailable)
The problem is that kernel irqchip is not created with irqfd_test, and
function kvm_arch_intc_initialized() returns false on LongArch.
/*
* returns true if the virtual interrupt controller is initialized and
* ready to accept virtual IRQ. On some architectures virtual interrupt
* controller is dynamically instantiated and this is not always true.
*/
bool kvm_arch_intc_initialized(struct kvm *kvm);
On LoongArch virtual irqchip is dynamically created by VMM.
