From a5367ecb5353fbf28bfd3979fc4f61ddebec80b1 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Mon, 11 Jul 2022 12:32:05 +0300 Subject: perf tools: Automatically use guest kcore_dir if present When registering a guest machine using machine_pid from the id index, check perf.data for a matching kcore_dir subdirectory and set the kallsyms file name accordingly. If set, use it to find the machine's kernel symbols and object code (from kcore).
