72 context switches to ensure the computations performed by each FPU user
83 treats *all* threads as FPU users when shared FP registers mode is enabled.
145 On the ARM64 (Aarch64) architecture the kernel treats each thread as a FPU
149 FPU user to a non-user thread, and then back to the original FPU user.
151 FPU register usage by ISRs is supported although not recommended. When an
153 current FPU user context is saved in the thread object and the ISR is resumed
155 and potentially requesting FPU usage. Because ISR don't have a persistent
156 register context, there are no provision for saving an ISR's FPU context
166 or FPU user and the thread must be tagged by one of the
