In the Linux kernel, fpstate represents the structure holding these architectural register values when a thread is not actively running on a CPU core. Because saving kilobytes of data on every single context switch introduces massive latency, the kernel must manage this space dynamically. 2. Dynamic vs. Fixed FPU State Allocation

Dynamically allocating an 8 KB buffer mid-context-switch causes unpredictable spikes in latency (jitter).
