Created attachment 330941 [details] fix EPT cache attributes Description of patch: hardcode UC for mmio of assigned devices in ept table similarly to what was done for p2m. Upstream Status: Accepted (in a different form) This patch differs from upstram since it is a simplification, upstream uses a more invasive change to allow finer grain control through the MTRR/PAT registers, more flexible but not needed for the current use cases for VTd.
