Includes software library files providing API's for Please refer to INSTALL file for package installation instructions. This software package is maintained, updated and developed on Note that proper operation of these APIs depends on availability and PID API compile time option has been removed and the APIs are always available. To manage Intel(R) RDT in an OS compatible way. Presence of these interfaces and allows to select the preferred one throughĪs the result, existing tools like 'pqos' or 'rdtset' can also be used Recommended that CPUID enumeration should be used wherever possible.įrom software version v1.0.0 the library adds option to use Intel(R) RDT viaĪvailable OS interfaces (perf and resctrl on Linux). Specific MSR’s to discover hardware capabilities, however it is This brand string is read from CPUID and compared to a table (model-specific) implementation exists) it can be detected via brand Supported on a particular SKU (but instead a non-architectural In a limited number of special cases where CAT is not architecturally Implementations, presence of the technologies is detected via the MSR access is arranged via a standard operating system driver: Model Specific Registers (MSR) on a hardware thread basis. In principle, the software programs the technologies via Intel(R) Resource Director Technology (Intel(R) RDT) including:Ĭache Monitoring Technology (CMT), Memory Bandwidth Monitoring (MBM),Ĭache Allocation Technology (CAT), Code and Data Prioritization (CDP) This software package provides basic support for
