class wlauto.instrumentation.pmu_logger.CciPmuLogger(device, **kwargs)[source]¶

description = "\n This instrument allows collecting CCI counter data.\n\n It relies on the pmu_logger.ko kernel driver, the source for which is\n included with Workload Automation (see inside ``wlauto/external`` directory).\n You will need to build this against your specific kernel. Once compiled, it needs\n to be placed in the dependencies directory (usually ``~/.workload_uatomation/dependencies``).\n\n .. note:: When compling pmu_logger.ko for a new hardware platform, you may need to\n modify CCI_BASE inside pmu_logger.c to contain the base address of where\n CCI is mapped in memory on your device.\n\n This instrument relies on ``trace-cmd`` instrument to also be enabled. You should enable\n at least ``'bprint'`` trace event.\n\n "¶
