From e1415b9418eb22b4a7a1ef4b4aec9dd0a49e3fa7 Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Wed, 25 Mar 2026 12:26:38 -0700 Subject: [PATCH 1/8] platform/x86: ISST: Reset core count to 0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Based on feature revision, number of buckets can be less than the TRL_MAX_BUCKETS. In that case core counts in the remaining buckets can be set to some invalid values. Hence reset core count to 0 for all buckets before assigning correct values.
