When using the Statistical Profiling Extension (SPE) support in Streamline, there are some more system requirements.
Use Linux kernel 4.16 or later. To confirm that support is available, check for the path /sys/bus/event_source/devices/arm_spe_XX.
Disable kernel page table isolation for the target. To ensure that kernel page table isolation is disabled, boot the device with the command-line argument kpti=off.
For kernel versions 4.20 and later, apply the patch at http://lkml.iu.edu/hypermail/linux/kernel/1903.3/06760.html, or upgrade to a kernel version greater than or equal to 5.1-RC5.
For more information about SPE, see Configure SPE counters in the Arm Streamline User Guide.
