L2 cache misses in Samsung Exynos 4 Quad using Streamline
Is it possible to measure PL310 events using the DS-5 Streamline? The target device is Samsung Galaxy S3 with Exynos 4 Quad SoC and Cortex A9 cores. The device runs Android.

Yes, this should work fine when using a recent version of gator.
I'd recommend to use gator v17, shipped in DS-5 5.17.1 (latest), which can be downloaded here: ARM Development Studio 5
After installing DS-5, gator can be found here: <DS-5_install_path>/arm/gator
Then, you will have to re-build the gator driver and daemon by following these instructions.
The PL310 counters have to added in the Streamline Configuration Window.
I hope this helps.
