Subject: [PATCH 01/32] perf evsel: Fix incorrect handling of type _TERM_DRV_CFG
Date: Wed, 17 Jan 2018 13:11:51 -0300	[thread overview]
Message-ID: <20180117161222.15611-2-acme@kernel.org> (raw)
In-Reply-To: <20180117161222.15611-1-acme@kernel.org>

From: Mathieu Poirier <mathieu.poirier@linaro.org>

Commit ("d0565132605f perf evsel: Enable type checking for
perf_evsel_config_term types") assumes PERF_EVSEL__CONFIG_TERM_DRV_CFG
isn't used and as such adds a BUG_ON().

Since the enumeration type is used in macro ADD_CONFIG_TERM() the change
break CoreSight trace acquisition.

This patch restores the original code.
