Running Average Power Limit Energy Reporting CVE . . . - Intel Intel recommends using the FIT Microcode Update mechanism described in the Microcode Update Guidance to apply the latest microcode update This mitigation implementation alters the internal RAPL energy reporting calculation algorithm and filters the energy information as compared to the previous legacy power reporting method
Running Average Power Limit (RAPL) – Exigence Running Average Power Limit is a feature introduced by Intel in their Sandy Bridge processors, which provides a way to monitor and control the energy consumption of various components within the processor package It allows for real-time measurement and enforcement of power limits, helping to optimise power usage and thermal management
RAPL analysis tests on a laptop - Intel Communities I am testing the RAPL feature a laptop in a way to try to read some CPU consumption values and I need someone to help me getting some answers Well, I am running a RAPL sample code simultaneously with a total battery power consumption code and I am getting the following values: ##RAPL: Package energy before: 5743 516907J
Mitigating the last L1 terminal fault vulnerabilities . . . The required microcode is the same microcode that addresses CVE-2018-3639 and CVE-2018-3640 The last 8700K microcode is Rev 0x96 (see picture as well) So all the pieces should fall into place, yet they don't
RAPL, SGX and energy filtering - Influences on power . . . Intel has reacted directly with a microcode update that results in distorting the RAPL signal when SGX is enabled in the system Alternative to that the user may also set a register in the processor to activate the so called energy filtering even when SGX is disabled
