This is because when using PID namespace a process id (ie. VPID) seen from the current namespace differs from the id (ie. PID) seen by kernel. This patch-set does add a translation between VPID and PID. Chunyan Zhang (5): coresight-etm3x: Change the name of the ctxid_val to ctxid_pid coresight-etm4x: Change the name of the ctxid_val to ctxid_pid Coresight: Add an interface for supporting ETM3/4 Context ID tracing coresight-etm3x: Support context-ID tracing when PID namespace is enabled coresight-etm4x: Support context-ID tracing when PID namespace is enabled .../ABI/testing/sysfs-bus-coresight-devices-etm3x | 2 +- .../ABI/testing/sysfs-bus-coresight-devices-etm4x | 2 +- drivers/hwtracing/coresight/coresight-etm.h | 7 ++-- drivers/hwtracing/coresight/coresight-etm3x.c | 28 +++++++++------- drivers/hwtracing/coresight/coresight-etm4x.c | 37 ++++++++++++++-------- drivers/hwtracing/coresight/coresight-etm4x.h | 7 ++-- include/linux/coresight.h | 20 ++++++++++++ 7 files changed, 72 insertions(+), 31 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
