A Dkernel_mode_neon.rst7 * Use only NEON instructions, or VFP instructions that don't rely on support
20 code that runs in kernel mode. However, for performance reasons, the NEON/VFP

30 The NEON/VFP register file is managed using lazy preserve (on UP systems) and
35 every context switch, resulting in a trap when subsequently a NEON/VFP
40 it is required to do an 'eager' preserve of the NEON/VFP register file, and
41 enable the NEON/VFP unit explicitly so no exceptions are generated on first
56 * NEON/VFP code is not allowed in interrupt context;
57 * NEON/VFP code is not allowed to sleep;
58 * NEON/VFP code is executed with preemption disabled.
