Arm® Mali™ Timeline Events are supported on Linux from DDK version r43p0. This topic details some more system requirements to support Mali Timeline Events.
Enabling support for the Mali Timeline requires the following actions:
Manually set the environment variable MALI_GPU_RENDERSTAGES_ENABLE=1
Compile the driver with instrumentation and profiling support, and ensure the Perfetto traced daemon is running.
To start profiling, configure the environment variable before starting the target application. As it starts, the driver checks the variable to see if it needs to start a profiling session and publish information to the Perfetto daemon.
