From 0d57b49992200a926c4436eead97ecfc8cc710be Mon Sep 17 00:00:00 2001 From: Beata Michalska Date: Thu, 21 Nov 2019 00:08:43 +0000 Subject: target/arm: Add support for DC CVAP & DC CVADP ins ARMv8.2 introduced support for Data Cache Clean instructions to PoP (point-of-persistence) - DC CVAP and PoDP (point-of-deep-persistence) - DV CVADP. Both specify conceptual points in a memory system where all writes that are to reach them are considered persistent. The support provided considers both to be actually the same so there is no distinction between the two. If none is available (there is no backing store for given memory) both will result in Data Cache Clean up to the point of coherency. Otherwise sync for the specified range shall be performed.
