NAME
libpfm_intel_ivb_unc - support for Intel Ivy Bridge uncore PMU SYNOPSIS
#include <perfmon/pfmlib.h> PMU name: ivb_unc_cbo0, ivb_unc_cbo1, ivb_unc_cbo2, ivb_unc_cbo3 PMU desc: Intel Ivy Bridge C-box uncore DESCRIPTION
The library supports the Intel Ivy Bridge client part (model 58) uncore PMU. The support is currently limited to the Coherency Box, so called C-Box for up to 4 physical cores. Each physical core has an associated C-Box which it uses to communictate with the L3 cache. The C-boxes all support the same set of events. However, Core 0 C-box (snb_unc_cbo0) supports an additional uncore clock ticks event: UNC_CLOCKTICKS. MODIFIERS
The following modifiers are supported on Intel Ivy Bridge C-Box uncore PMU: i Invert the meaning of the event. The counter will now count cycles in which the event is not occurring. This is a boolean modifier e Enable edge detection, i.e., count only when there is a state transition from no occurrence of the event to at least one occurrence. This modifier must be combined with a counter mask modifier (m) with a value greater or equal to one. This is a boolean modifier. c Set the counter mask value. The mask acts as a threshold. The counter will count the number of cycles in which the number of occur- rences of the event is greater or equal to the threshold. This is an integer modifier with values in the range [0:255]. Both the UNC_CBO_CACHE_LOOKUP and UNC_CBO_XSNP_RESPONSE requires two umasks to be valid. For UNC_CBO_CACHE_LOOKUP the first umask must be one of the MESI state umasks, the second has to be one of the filters. For UNC_CBO_XSNP_RESPONSE the first umask must be one of the snoop types, the second has to be one of the filters. AUTHORS

NAME
libpfm_intel_x86_arch - support for Intel X86 architectural PMU SYNOPSIS
#include <perfmon/pfmlib.h> PMU name: ix86arch PMU desc: Intel X86 architectural PMU DESCRIPTION
The library supports any processor implementing the Intel architectural PMU. This is a minimal PMU with a variable number of counters but predefined set of events. It is implemented in all recent processors starting with Intel Core Duo/Core Solo. It acts as a default PMU support in case the library is run on a very recent processor for which the specific support has not yet been implemented. MODIFIERS
The following modifiers are supported on Intel architectural PMU: u Measure at user level which includes privilege levels 1, 2, 3. This corresponds to PFM_PLM3. This is a boolean modifier. k Measure at kernel level which includes privilege level 0. This corresponds to PFM_PLM0. This is a boolean modifier. i Invert the meaning of the event. The counter will now count cycles in which the event is not occurring. This is a boolean modifier e Enable edge detection, i.e., count only when there is a state transition. This is a boolean modifier. c Set the counter mask value. The mask acts as a threshold. The counter will count the number of cycles in which the number of occur- rences of the event is greater or equal to the threshold. This is an integer modifier with values in the range [0:255]. t Measure on both threads at the same time assuming hyper-threading is enabled. This modifier requires at least version 3 of the architectural PMU. This is a boolean modifier. AUTHORS
