Hi Qiang,
what you did is good.
The messages shown are giving hints on the setup and are not generally
bad.
If the ioproxy says there's no resource it means that a device/resource
is listed in the device tree but not on the vbus, i.e. this resource is
not available for the VM. uvmm thus disables this node in the device
tree.
The platform_ctl cap message is coming from io, telling us that io
cannot offer the Platform_control API because no cap has been made
available.
Regarding the UART, there's also a hint, and I believe that is also the
reason why no output from Linux is seen. You already noticed as well.
pl011 and linflex are not compatible. What I would propose is that you
add a node in the DT for the pl011, as uvmm can emulate this UART type.
An example can be found in pkg/uvmm/configs/dts/vmm-devices-arm.dtsi.
This file contains two variants of a UART. The pl011 one which I just
mentioned and a virtio-console one. Both will work. You can take the
contents of this file as is, however pay attention to the MMIO ranges
and IRQs used. Choose a free range in the guest physical address space
of your guest (aka a range not used in the device tree) and change the
addresses accordingly. Similar with the interrupts, use one not used
previously.
