Yonghua Huang
 

Minor corrections for below :

  1. vRTCT is in SOS or Hypervisor ?

         A: For Pre-launched VM, RTCT is pass-through, for post-launched, vRTCT is built in SOS/DM.

  1. Does Software SRAM support L3 cache?

      A: Yes, both L2 and L3 are supported for Post-launched RTVM and Only L3 is supported in ACRN on platform that Software SRAM is supported.  

 

 

Thanks.
