- Jun 20, 2026 Energy-Optimal Operating Points and the Shape of DVFS Why the lowest voltage a circuit can run at is not the most efficient one, how frequency and voltage must move together, and where the energy minimum sits for a real workload. hardware engineering
- Apr 4, 2026 Thermal Throttling: Duty Cycles, Ratio Capping, and Power Limits How a processor detects that it is too hot or drawing too much, which of several limiters acts first, and what each one does to frequency, voltage, and the workload's timing. hardware engineering
- Jan 2, 2026 Clock Derating and the Roofline That Moves Why the ceiling a kernel is measured against depends on power state and duration, and how sustained clocks change which side of the ridge a kernel occupies. gpu computing
- Dec 30, 2025 Timer Coalescing and the Deferrable Work Budget How a kernel batches timer expiries, how slack and tolerance let a deadline drift, and why a wakeup that can wait is worth more than one that cannot. mobile computing
- Nov 13, 2025 Wake Locks, Reference Counting, and the Cost of a Held CPU Why a wake lock is a counted system resource rather than a flag, what a partial lock actually keeps powered, and how an unbalanced acquire turns into a battery complaint. mobile computing
