  1. ACRN project update
  1. “ACRN GVT-d Introduction and Tutorial” by ZHAO, Yakui
Download foil from ACRN Presentation->ACRN_TCM->WW21’20
Description: ACRN GVT-d overview Architecture Introduction and Tutorial, we will talk about what is GVT-d, the design in ACRN and demonstrate how to enable it in ACRN.
  1. All: Community open discussion.
Q1: GVT-g and GVT-d are both supported on ACRN, you can choose/config either GVT-g for multi-display/VM, or GVT-d for one display/VM with better graphic performance, based on your real user scenario.
Q2: After config/passthru GPU to one UOS, if the UOS is shut down, we don’t recommend returning the GPU(i915 driver) back to SOS, but resume the UOS quickly.
Q3: Solen memory for GTV-d, reserved specific memory range(64M) for UOS and built EPT to map memory addresses.
Q4: Performance comparison of GVT-d and GVT-g:  there is extra performance overhead with GVT-g, but GVT-d is almost the same performance as native.
Q5: gvt-d, is there any dependency on specific OS drivers (either in windows or Linux) ? or just native GPU drivers ?  No specific dependency, just use native GPU driver.
