2015-12-17perf cpu_map: Add cpu_map user level eventJiri Olsa4-1/+81
Adding the cpu_map event to pass/store cpu maps as data in a pipe/perf.data. We store maps in 2 formats: - list of cpus - mask of cpus The format that takes less space is selected transparently in the following patch. The interface is made generic, so we could add the cpumap event data into another event in the following patches.

2015-12-17selftests/powerpc: Add script to test HMI functionalityDaniel Axtens1-0/+89
HMIs (Hypervisor Management|Maintenance Interrupts) are a class of interrupt on POWER systems. HMI support has traditionally been exceptionally difficult to test, however Skiboot ships a tool that, with the correct magic numbers, will inject them. This, therefore, is a first pass at a script to inject HMIs and monitor Linux's response. It injects an HMI on each core on every chip in turn It then watches dmesg to see if it's acknowledged by Linux. On a Tuletta, I observed that we see 8 (or sometimes 9 or more) events per injection, regardless of SMT setting, so we wait for 8 before progressing. It sits in a new scripts/ directory in selftests/powerpc, because it's not designed to be run as part of the regular make selftests process. In particular, it is quite possibly going to end up garding lots of your CPUs, so it should only be run if you know how to undo that.
