How to become AMD partner

We are looking for becoming AMD partner. Although I've found information for partners at AMD site, there is no form in order to formally request a partner agreement.

Our company is developing a cloud gaming platform and we are looking for an agreement with AMD in order to have direct link with product designer at GPUs level for a Cloud Gaming service, access to development roadmap in order to plan our next technological iterations and / or ask for development support at driver level.

How do we proceed?

Thanks in advance
