Does someone use the PERF "Performance Events for Linux", the standard profiling infrastructure on Linux with the sabrelite I.MX6 board?
the PERF is used to analyze the performance of an executed program by monitoring in real time the hardware events (e.g. cpu-cycles, instructions, cache-misses, .... Etc).
By using the SABRE-LITE IMX.6 with the Ubuntu Trusty image (3.14.28 or the updated 3.14.52) i.MX Linux kernel 3.14.52 - Boundary Devices the PERF tools doesn't work, the terminal response is:
root@nitrogen:/home/ubuntu# perf --help
WARNING: perf not found for kernel 3.14.52-6
You may need to install the following packages for this specific kernel:
You may also want to install one of the following packages to keep up to date:
And then when i want to download the specific package, using apt-get or aptitude Linux doesn't find the matched package.
Thanks for help,
