once running 'hailortcli run test.hef" I get following warning message:
[HailoRT] [warning] Requested desc page size (512) is bigger than max on this host (256).

Some hosts doesn’t support certain PCIe descriptor page size.
in order to over come this issue you can do one of the following:

  1. remove the module and the install it back with force_desc_page_size=256
modprobe -r hailo_pci modprobe hailo_pci force_desc_page_size=256
  1. add the below under /etc/modprobe.d/hailo_pci.conf:
options hailo_pci force_desc_page_size=256

Similar error can also be seen while trying to inference using pyhailoRT:
[HailoRT] [error] CHECK_AS_EXPECTED failed - max_desc_page_size given 16384 is bigger than hw max desc page size 4096"

In this case the solution is the same as mentioned in the previous post, just set the max_desc_page_size to the relevant size mentioned in the error (e.g. 4096)
