Nicolas Pitre a211970b42 riscv: improve contended FPU switching ... We can leverage the FPU dirty state as an indicator for preemptively reloading the FPU content when a thread that did use the FPU before being scheduled out is scheduled back in. This avoids the FPU access trap overhead when switching between multiple threads with heavy FPU usage. Signed-off-by: Nicolas Pitre <npitre@baylibre.com>		2023-01-24 15:26:18 +01:00
