MA35D1 打RT_PREEMPT后编译异常

发表于 2023-8-7 10:56

往MA35D1内核5.10.140版本打入RT_PREEMPT实时补丁编译内核报错，出现下面错误：

      drivers/spi/spi-ma35d1-qspi.c: In function ‘nuvoton_spi_probe’:
      ./include/linux/spinlock_types_rt.h:32:2: error: expected expression before ‘{’ token
            32 | { .lock = __RT_SPIN_INITIALIZER(name.lock), \
                  | ^

         973 | nuvoton->slave_txdone.lock = __SPIN_LOCK_UNLOCKED(nuvoton->slave_txdone.lock);

你的 Linux 内核版本是什么？

参考文档里的下面方式修改即可：

修改./driver/spi/spi-ma35d1-spi.c line 905

修改./driver/spi/spi-ma35d1-spi.c line 969

原代碼為

nuvoton->slave_done.lock = __SPIN_LOCK_UNLOCKED(nuvoton->slave_done.lock);

修改為

#ifndef CONFIG_PREEMPT_RT

nuvoton->slave_done.lock = __SPIN_LOCK_UNLOCKED(nuvoton->slave_done.lock);

#else

nuvoton->slave_done.lock = (spinlock_t)__SPIN_LOCK_UNLOCKED(nuvoton->slave_done);

#endif
