Hello,

I have a problem running the ./zynqmp_demo.
My setup:
Ubuntu 20.04
systemc-2.3.3
petalinux 2021.2
xilinx-zcu102-v2021.2-final.bsp
qemu-devicetrees/LATEST/MULTI_ARCH/zcu102-arm.cosim.dtb

All works well apart from when the QEMU session it disconnects at the following;

Any ideas what might be causing this?

[edgarigl]

Hi Aron,

Have you possibly edited the zynqmp_demo.cc file? I don't recognize the top.simple_target_socket_1 socket.
If you've added it intentionally, you'll need to implement the b_transport functions for it so it can receive traffic.

Best regards,
Edgar

[edgarigl]

Hi,

Francisco just mentioned to me that this could be related to accesses to Zynq PS ports that are not connected (tied off).
I wonder what address that could be. We should probably change our tie off could to print debug messages when receiving transactions...

Best regards,
Edgar

[albaEDA]

@edgarigl

Thanks for the swift reply, the only thing I have modified with zynqmp_demo.cc is moving from systemc-2.3.2 -> systemc-2.3.3.

To give a bit of background, the following works fine for me;
Ubuntu 18.04
systemc-2.3.3
petalinux 2020.2
xilinx-zcu102-v2021.2-final.bsp
qemu-devicetrees/LATEST/MULTI_ARCH/zcu102-arm.cosim.dtb

but when I move to ubuntu 20.04 and compile with petalinux 2020.2 it fails to create a workspace, i tried xilinx-zcu102-v2020.2-final.bsp, this compiles but as soon as zynqmp_demo connect to the port it causes a segmentation error on QEMU (unknown why).

I did a bit of digging and it seems like someone else is having the same issue on the forums:
https://support.xilinx.com/s/question/0D52E000070qcyUSAQ/hello-i-am-running-cosimulation-for-zynqmp-zcu102-bsp-starting-kernel-has-been-interrupted-see-below-qemusystemaarch64-amba0cosim0-disconnected-clk4564465595-nsthank-you?language=en_US

They didn't give any environment details but I'm guessing it could be Ubuntu 20.04 / Petalinux 2021.2?

Anyway, some debug messages would be great I tried stepping through the execution with GDB but ended up down a rabbit hole. Do you have any debug switches to make the output any more vebrose?

Thanks for your time

[franciscoIglesias]

Hi Aron,

Could you try connecting the zynq.s_axi_hpm_lpd similar to zynq.s_axi_hpm_fpd[0]?

//
// In zynqmp_demo.cc
//
-#define NR_MASTERS	1 + NR_DEMODMA
+#define NR_MASTERS	2 + NR_DEMODMA
...
                zynq.s_axi_hpm_fpd[0]->bind(*(bus.t_sk[0]));
+               zynq.s_axi_hpm_lpd->bind(*(bus.t_sk[1]));

Below gives me the impression that an access to the hpm_lpd area is being made (and if the socket is not connect to the 'bus' above will happen):

[    0.000000] irq-xilinx: /amba_pl@0/interrupt-controller@80020000: num_irq=32, sw_irq=0, edge=0x1

Best regards,
Francisco Iglesias

[albaEDA]

@franciscoIglesias

Hey Francisco,

Making those changes I see the following systemc runtime error on zynqmp_demo

Error: (E109) complete binding failed: port not bound: port 'top.bus.target_socket_5_port_0' (sc_port)

Maybe the DMA binding needs moved around?

Thanks

[franciscoIglesias]

Hi Aron,

Yes that's right (sorry for missing that!), the DMA needs to be connected on the target sockets following hpm_lpd (2+i) as below:

-                       dma[i]->init_socket.bind(*(bus.t_sk[1 + i]));
+                       dma[i]->init_socket.bind(*(bus.t_sk[2 + i]));

Best regards,
Francisco Iglesias

[albaEDA]

So I changed it to
zynq.s_axi_hpm_lpd->bind(*(bus.t_sk[5]));
instead as I didn't want to edit the DMA code incase it was used elsewhere and now it it runs to:

[franciscoIglesias]

Hi Aron,

Above happens because there is no model connected at the target address of the accesses (transactions) on the interconnect (bus).

Best regards,
Francisco Iglesias

[albaEDA]

Hey @franciscoIglesias

So would that mean adding something like?
bus.memmap(0x0LL, 0xffffffff - 1, ADDRMODE_RELATIVE, -1, *(zynq.s_axi_hpc_fpd[0]));

Is there a way to add an empty model? Could you also shed some light on why I don't see the same issues on Ubuntu 18.04 / Petalinux 20.02?

Thanks for your time

[franciscoIglesias]

Hi Aron,

You can follow the debugdev (debugdev.h and debugdev.cc ) for how to create and connect a relatively simple model.

If petalinux 20.02 runs I think it is because the kernel (or kernel dtb) is not configured to use above driver (the kernel driver tries to access a model of the interrupt controller at above position).

Best regards,
Francisco Iglesias

If petalinux 20.02 runs I think it is because the kernel (or kernel dtb) is not configured to use above driver (the kernel driver tries to access a model of the interrupt controller at above position).

I thought more about this and decided to check the device tree and I think you are right, if I make the change to remove the following:
https://github.com/Xilinx/qemu-devicetrees/blob/0499324af1178057c3730b0989c8fb5c5bbc4cf8/zynqmp-pl-remoteport.dtsi#L41-L46
It works without any modification, I think I was using an older version of the qemu-device tree and assumed nothing had changed. Thanks for the pointer! How can we highlight / fix this for anyone who stumbles across this?

Thank you for your time!
