Assistance with DPDK on Windows

Hi Team ,
I am currently working with DPDK on Windows and have followed the setup instructions provided in the official guide: https://doc.dpdk.org/guides-25.07/windows_gsg/index.html.
I have a couple of queries:

  1.
Is it possible to execute or use dpdk-devbind.py on Windows to verify the device binding status?
  2.
On Windows, the build generates .dll files (e.g., rte_net_driver.dll) instead of .so files (e.g., librte_net_driver.so in Linux). How can we use or execute these .dll files in the same way we use .so files when running DPDK applications?

Kindly provide your guidance on these points.
Thank you for your time and support.
Best regards,
Thenveer Poolakkanni

No. Please use Device Manager for now.

The application must link the needed libraries and PMDs when building. 
These files must be in PATH or in the working directory when running the 
application. Loading additional PMDs with "-d" EAL option is not yet 
implemented. If you have a custom PMD you have to build it as a part of 
DPDK and link to your application.


P. S. Questions like these belong to users@dpdk.org. Keeping in dev@ to 
avoid breaking threads.

This question is probably showing a lack of documentation.
Please can we have this gap solved with a patch?
