From 8352756ffa72668773d6904bc76dfc0bf2619e5a Mon Sep 17 00:00:00 2001 From: Ajay Joshi Date: Mon, 14 Oct 2024 13:18:57 +0100 Subject: [PATCH] hw/cxl: Fix background completion percentage calculation The current completion percentage calculation does not account for the relative time since the start of the background activity, this leads to showing incorrect start percentage vs what has actually been completed. This patch calculates the percentage based on the actual elapsed time since the start of the operation.
