P1015 Performance Monitoring - is sample driver code available for enabling and displaying the Performance Monitoring data specifically for PCIe/

rhilderman — Thu, 12 Nov 2015 22:24:37 GMT

We are trying to get PCIe utilization using the performance monitoring capabilities on the P1015 processor (we are running VxWorks 6.9). If sample code for enabling and displaying this data can be provided, that would be appreciated.

Thanks,

Randy

You can make use of performance monitor hardware from scratch.

The e500 performance monitor driver exists in the kernel. The core API is in arch/powerpc/perf/core-fsl-emb.c and e500 related stuff is in arch/powerpc/perf/e500-pmu.c.

Bare-board example in CodeWarrior PA:

Have a great day,
