Subject: [PATCH 4.16 24/68] perf intel-pt: Fix error recovery from missing TIP packet
Date: Tue, 17 Apr 2018 17:57:37 +0200 [thread overview]
Message-ID: <20180417155750.329344267@linuxfoundation.org> (raw)
In-Reply-To: <20180417155749.341779147@linuxfoundation.org>
4.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: Adrian Hunter <adrian.hunter@intel.com>
commit 1c196a6c771c47a2faa63d38d913e03284f73a16 upstream.
When a TIP packet is expected but there is a different packet, it is an
error. However the unexpected packet might be something important like a
TSC packet, so after the error, it is necessary to continue from there,
rather than the next packet. That is achieved by setting pkt_step to
zero.
