+description = """According to the info in generated dtb, the memory-mapped registers of gicv3-distributor have a base addr, which is `0x0800_0000`.
+And I have checked the validity by reading `gicd_typer`, which means the base addr is right.
+
+But when I want to configure the gicv3-distributor (like changing `gicd_ctlr`), the value is not changed, keeping the default value. The same thing happens on any register of GICD in my machine.
+
+**Even I write to this memory by gdb `set` command, the value is also unchangeable.**
+
+The addr of `gicd_ctlr` should be `0x0800_0000`(offset=0), which should be readable and writable, isn't it?
+
+I try to modify the value of this addr in assembly as soon as the **machine starts, without enabling MMU**. 
+This problem should be easier to reproduce."""
