[perfmon2] How to reset sampling buffer before it overflows?

hi, I am writing my own app using the libpfm 3.10 API (interface v2.x) on a X86 system. I setup a sampling context for the target-process to sample every 1 million insts retired. Traditionally, I should wait for the buffer overflow message and process with the sampling buffer and then restart. Bu

[perfmon2] [libpfm4] how to turn off sampling period randomization

hi all, I am new to libpfm v4. I read the example code "task_smpl.c", which uses random sampling periods, but I didn't find any explicit statement to turn this feature on. So, how to turn off sampling period randomization? I am using the official Linux 2.6.35 kernel. Thanks. 2010-10-20

[perfmon2] Weird sampling result on Xeon E5410 CPU

Hi all, I'm working with a system with Xeon E5410 processors. The Linux kernel version is 2.6.27, and libpfm/pfmon v3.6 (released on 2008-10-13). The pfmon command line I used was: pfmon --smpl-outfile=x --with-header --smpl-module=compact --follow-all --reset-non-smpl-periods --overflow-blo

[perfmon2] Possibility of getting COMPLETE cache access trace using PEBS

Hi all, I am wondering if I can get continuous sampling about every L2$ access with PEBS on Xeon E5410 processor. PEBS feature records the value of general registers on sample points, so I can get the data address trace of L2$ access with disassembly. The naive way is to set the L2$ access event
