| D | kernel_mode_neon.rst | 7 * Use only NEON instructions, or VFP instructions that don't rely on support
19 It is possible to use NEON instructions (and in some cases, VFP instructions) in
20 code that runs in kernel mode. However, for performance reasons, the NEON/VFP
24 may call schedule()], as NEON or VFP instructions will be executed in a
30 The NEON/VFP register file is managed using lazy preserve (on UP systems) and
33 contending for the NEON/VFP unit (or, in the SMP case, when a task migrates to
34 another core). Lazy restore is implemented by disabling the NEON/VFP unit after
35 every context switch, resulting in a trap when subsequently a NEON/VFP
39 Any use of the NEON/VFP unit in kernel mode should not interfere with this, so
40 it is required to do an 'eager' preserve of the NEON/VFP register file, and
