Yes. The article says the Linux patch extends topology to recognize a Low Power core class via CPUID, implying software that uses core-count or affinity masks will need to recognize the new LP class to avoid scheduling heavy workloads onto LP cores.

Linux and Windows will use the new CPUID flag (Fn0x80000026, EBX bits 31:28) value 2 to identify Low Power (LP) cores and treat them as a separate core class from existing Performance and Efficiency cores. The patch notes that boost scaling for LP cores will follow the same method AMD already uses for Efficiency cores, so schedulers can prioritize LP cores for minimal-power background and idle work while keeping Zen 6c and full Zen 6 cores for higher-performance tasks.

The epp_boost patch fixes an inefficiency in AMD's P-State driver where brief sleeps by a game thread (for example while waiting on the GPU) are misinterpreted as lower CPU demand, causing cores to downclock and then resume at too-low frequencies. That behavior produces momentary frame time inflation, stutters, and 1% low FPS spikes on Steam Deck and other AMD Linux systems. The patch addresses this by temporarily boosting busy cores to performance mode based on per-core activity checks. Answered

The epp_boost patch samples each core every 10 milliseconds and, if a core is at least 50% busy, temporarily switches that core to performance mode. It reverts the core back to the normal EPP policy once activity drops and remains low for 300 milliseconds. Answered
