From ebf39d29b985b0c0f75c2e752781a9a80daadc0e Mon Sep 17 00:00:00 2001 From: Leo Yan Date: Wed, 15 Mar 2023 22:51:05 +0800 Subject: perf hist: Add 'kvm_info' field in histograms entry __hists__add_entry() creates a temporary entry and compare it with existed histograms entries, if any existed entry equals to the temporary entry it skips to allocation to avoid duplication. The problem for support KVM event in histograms is it doesn't contain any info to identify KVM event and can be used for comparison entries. This patch adds 'kvm_info' field in the histograms entry which contains the KVM event's key, this identifier will be used for comparison histograms entries in later change.
