linux - Which perf events can use PEBS? - Stack Overflow I want to understand which events can have the precise modifier on my CPU (Sandy Bridge) Intel Software Developer's Manual (Table 18-32 PEBS Performance Events for Intel Microarchitecture Code N
performance - Good resources on how to program PEBS (Precise event . . . So I was looking to program these PEBS counters on my own Has anybody had experience manipulating the PEBS counters ? Specifically I was looking for good sources to see how to program them I have gone through the Intel documentation and understood the steps But I wanted to understand some sample programs I have gone through the below github
x86 - How can I measure IPC using PEBS? - Stack Overflow PEBS is a sampling mechanism that Intel CPUs provide for sampling performance monitors Is it possible to use PEBS to measure a process's IPC? How does PEBS determine when to sample?
Using PEBS PMU in QEMU to sample exact addr of memory operation 1 I'm trying to use PEBS PMU in QEMU to sample exact addr of memory operation, I met a similar problem which is mentioned 3 years ago in this link and I quote the text part below I tried to use perf_event_open () to track all the store instructions to get their access address
x86-64 linear address for PEBS from Linux userspace? Is it possible to use the Haswell CPU feature PEBS (Precise Event Based Sampling) directly from a Linux userspace process instead of using a kernel interface? I have succeeded in accessing performance counters from userspace using the RDPMC instruction and only using the kernel for WRMSR
Using linux perf and PEBS to sample memory accesses in a program I've been trying to use the linux perf tool to sample the memory accesses in my program Specifically, I'm using the perf mem command to instrument the loads in the program: perf mem -t load rec
linux - PEBS records much less memory-access samples than actually . . . I have been trying to log memory accesses that are made by a program using Perf and PEBS counters My intention was to log all of the memory accesses made by a program (I chose programs from SpecCPU2006) By tweaking certain parameters, I seem to record much more samples than there actually is for the program
