Pmctools: PMC Hardware

This wiki page will describe PMC hardware supported by hwpmc(4). This page is currently a stub.

(To be filled in)

• Per-CPU counters.
• Chipset (i.e., motherboard) counters.
• Shared counters (Intel P4-only)

Dependent/Independent counters, examples of these.

(to be described in more detail)

• AMD Athlon XP
• AMD Athlon64 and Opteron
• Intel Pentium Pro, P-II, P-III, Celeron, Pentium-M.
• Intel P4/HTT

I have access to the following hardware.

• [wiki:PmcTools/PmcHardwareIntelCore Intel Core Solo/Duo PMCs]
• Sparc US-II PMCs.
• [wiki:PmcTools/PmcHardwarePowerPcG4 PowerPC G4]

… but for which I need access to hardware.

• Sparc T-1 PMCs. At a first glance, T-1's support needs hwpmc(4) like functionality in the hypervisor.
• Intel P5 PMCs. These CPUs are still sold in embedded devices. Such platforms could benefit from the availability of low-overhead system performance monitoring.
• VIA CPU PMCs. These CPUs popular for embedded work.
