From a1498ab229ca16dfc35331dfb309f8e28b84bb5d Mon Sep 17 00:00:00 2001 From: Michal Wajdeczko Date: Fri, 30 Aug 2024 15:20:59 +0200 Subject: [PATCH] drm/xe/pf: Add thresholds to the VF KLV config MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We are pushing threshold KLV to the GuC immediately during the threshold provisioning, but those configs will be lost during a GT reset. Include threshold KLVs while encoding full VF config buffer to make sure the GuC receives all of the config KLVs.
