2021-08-20perfmon: fix perf event user page readBenoît Ganne1-45/+76
When mmap()-ing perf event in userspace, we must adhere to the kernel update protocol to read consistent values.

2020-04-22misc: asan: do not poison memory after munmap()Benoît Ganne1-2/+0
It is a bad idea to poison memory after munmap because the address space can be reused (eg. for global data of dlopen()ed object) and ASan model allows access by default. Moreover, access to a stale address space will fault. Type: fix Change-Id: I356de422f255447d9d50a3a71fb0c2eaa790d731 Signed-off-by: Benoît Ganne <bganne@cisco.com>
2019-12-17perfmon: fix per-worker data initializationBenoît Ganne2-9/+14
When perfmon_init is called at initialization time worker threads are not created yet and vec_len(vlib_mains) returns 1. Initialize per-worker data when the number of workers is known, when enabling data collection instead.

2019-03-26perfmon: fix pmc hw indices out-dated when multiple pmcSu Wang1-3/+15
When adding two or more events using a single "set pmc", the pmc hardware indices might be out-dated due to kernel reschdeduling the perf_event hardware counters. E.g. set pmc cpu-cycles cache-misses Solution: Open and enable all the events first, then aquire the indices from the kernel.

2019-01-24perfmon plugin: 2-way parallel stat collectionDave Barach3-143/+228
As a FUD reduction measure, this patch implements 2-way parallel counter collection. Synthetic stat component counter pairs run at the same time. Running two counters (of any kind) at the same time naturally reduces the aggregate time required by an approximate factor-of-2, depending on whether an even or odd number of stats have been requested. I don't completely buy the argument that computing synthetic stats such as instructions-per-clock will be inaccurate if component counter values are collected sequentially. Given uniform traffic pattern, it must make no difference. As the collection interval increases, the difference between serial and parallel component counter collection will approach zero, see also the Central Limit theorem.
