You can add this into the CPUArchState structure, rather than reference via pointer. It
is always present with the cpu.
Neither of these are needed for CONFIG_USER_ONLY.
+void cpu_loongarch_store_stable_timer_config(CPULoongArchState *env,

+ uint64_t now, next;

+ env->CSR_TCFG = value;

+ timer_mod(env->timer, next);
+ }
timer_mod_ns, when you use timer_new_ns.
timer_del when not enabled.
+ env->timer = timer_new_ns(QEMU_CLOCK_VIRTUAL,
+ &loongarch_stable_timer_cb, env);
This would become
timer_init_ns(&env->timer, ...)
