SMP: Introduce spin_lock_irqsave() and spin_unlock_irqrestore() These APIs are simplified version of enter_critical_section() and leave_critical_section() to protect data (e.g. registers) in SMP mode. By using these APIs inside drivers, performace will be improved. Signed-off-by: Masayuki Ishikawa <Masayuki.Ishikawa@jp.sony.com> Approved-by: Gregory Nutt <gnutt@nuttx.org> |
