https://community.intel.com/t5/Graphics/Intel-FSP-Integration-with-custom-Hypervisor-for-Graphics/m-p/708769#M83820 <P>I am trying to integrate Intel FSP with Type-1 custom Hypervisor. Actually my FSP calling scenario is little different. When Windows guest call "Restart" service, Hypervisor has to call FSP Silicon Initialization API within FSP in order to re-initialize the devices specially Graphics Controller (as manually powering up HD Graphics controller is pity trivial task). I have ported FSP within Hypervisor but as soon as I call it, system gets corrupt which was very much expected. I have couple of questions to ask:</P><P>&nbsp;</P><P>Q-1 There are few FSP calling conditions, about two of them I am not sure enough if they are fulfilling. How can I make sure that following two conditions are meetings? Is there any assembly instruction in order to have a quick check?</P><P>1) System should be in flat 32-bit mode</P><P>2) Code and data selectors should have full 4GB access range.</P><P>&nbsp;</P><P>Q-2 Can anybody tell me how much doable is this task?</P><P>I mean FSP is not meant to be treated like, but i have no other choice other than following FSP approach for Initialization of Graphics subsystem. I tried manual Graphics setting up but I could not power up the graphics controller after reset.</P><P>&nbsp;</P><P>Q-3 Is there any alternative approach I can try for this specific task other than FSP?</P> Thu, 24 Jan 2019 14:38:40 GMT amhamza93 2019-01-24T14:38:40Z https://community.intel.com/t5/Graphics/Intel-FSP-Integration-with-custom-Hypervisor-for-Graphics/m-p/708769#M83820 <P>I am trying to integrate Intel FSP with Type-1 custom Hypervisor.
