Michael Petlan 8643df6436 perf intel-pt: Add support for emulated ptwrite ... Bugzilla: https://bugzilla.redhat.com/2123231 upstream ======== commit d7015e50a9ed180dcc3947635bb2b5711c37f48b Author: Adrian Hunter <adrian.hunter@intel.com> Date: Mon May 9 18:23:58 2022 +0300 description =========== ptwrite is an Intel x86 instruction that writes arbitrary values into an Intel PT trace. It is not supported on all hardware, so provide an alternative that makes use of TNT packets to convey the payload data. TNT packets encode Taken/Not-taken conditional branch information, so taking branches based on the payload value will encode the value into the TNT packet. Refer to the changes to the documentation file perf-intel-pt.txt in this patch for an example. Signed-off-by: Michael Petlan <mpetlan@redhat.com>		2022-09-21 07:23:04 +02:00
