From c0dd94558d0e473aa92254e1c48a47900c911e69 Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Thu, 25 Nov 2021 23:13:05 -0800 Subject: [PATCH] perf pmu-events: Don't lower case MetricExpr This patch changes MetricExpr to be written out in the same case. This enables events in metrics to use modifiers like 'G' which currently yield parse errors when made lower case. To keep tests passing the literal #smt_on is compared in a non-case sensitive way - #SMT_on is present in at least SkylakeX metrics.
