2.5.在lcm porting过程中，这些参数都定义在lcm_drv.h文件中的LCM_DSI_PARAMS结构体中，随着平台的发展，或许有所不同，但是基本原理都是一致的，如何配置clk的大小，请先根据自己的帧率、像素格式、porch值、屏的分辨率、data lane对数等计算出data_rate，然后计算出clk。这种模式是不需要带有显存的。VBPD(vertical back porch)： 表示在一帧图像开始时，垂直同步信号以后的无效的行数，对应驱动中的upper_margin；

MTK如何正确客制化写屏寄存器接口的方法

[DESCRIPTION]现在LCM功能越来越多，有些功能需要通过写寄存器的方式进行实时控制。这样就需要在lcm driver中额外客制化一个接口进行控制，但是由于对平台机制了解不够，导致客制化后，系统会发生低概率的HWT&SWT重启问题。[SOLUTION] 平台本身就有一个写寄存器接口可以参考（primary_display_setbacklight）。这里简单实现一个开关CABC(动态背光节

下面代码怎么优化 def update_running_state_to_restore(self): # Get audits that should be stashed. need_stash_audits = self.get_need_rollback_audits() need_suspend_audits = [] need_rollback_audits = [] for audit in need_stash_audits: self.record_audit_init_state(audit) if audit.goal.name in ['saving_energy', 'power_limit']: need_rollback_audits.append(audit) else: need_suspend_audits.append(audit) LOG.info("Audits need suspend are: %s", need_suspend_audits) LOG.info("Audits need rollback are: %s", need_rollback_audits) # The drs audits should be stopped in a timely manner, # so need to handle the drs audits first. for audit in need_suspend_audits: if audit.state == objects.audit.State.ONGOING: LOG.info("Suspend non-dpm audit: %s", audit.uuid) audit.state = objects.audit.State.SUSPENDED audit.save() for audit in need_rollback_audits: LOG.info("Begin to roll back audit: %s", audit.uuid) self.dc_client.rollback_audit(self.context, audit.uuid) # Confirm that the audit is rolled back completely self.confirm_audit_rolled_back(audit) disabled_nodes = self.get_watcher_disabled_nodes() LOG.info("Audits have all been updated, disabled nodes by watcher: %s", disabled_nodes) self.running_state.stash_audits = self.stash_audits self.running_state.watcher_disabled_nodes = disabled_nodes
07-12
这段代码可以进行一些优化。首先，可以使用列表推导式来简化对need_stash_audits的计算。 ```python need_stash_audits = [audit for audit in self.get_need_rollback_audits()] ``` 接下来，可以使用两个列表推导式来替代for循环和if语句，将需要回滚和需要暂停的审计分别提取出来。 ```python need_rollback_audits = [audit for audit in need_stash_audits if audit.goal.name in ['saving_energy', 'power_limit']] need_suspend_audits = [audit for audit in need_stash_audits if audit not in need_rollback_audits] ``` 然后，可以使用列表推导式和条件表达式来简化循环中的if语句。这样可以减少代码行数并提高可读性。 ```python for audit in need_suspend_audits: LOG.info("Suspend non-dpm audit: %s", audit.uuid) audit.state = objects.audit.State.SUSPENDED if audit.state == objects.audit.State.ONGOING else audit.state audit.save() for audit in need_rollback_audits: LOG.info("Begin to roll back audit: %s", audit.uuid) self.dc_client.rollback_audit(self.context, audit.uuid) self.confirm_audit_rolled_back(audit) ``` 最后，注意到在代码的最后几行中，通过赋值操作更新了`self.running_state`的两个属性。可以将这两个属性的赋值操作放在代码的开头，以便更早地更新状态。 ```python self.running_state.stash_audits = self.stash_audits self.running_state.watcher_disabled_nodes = self.get_watcher_disabled_nodes() LOG.info("Audits have all been updated, disabled nodes by watcher: %s", self.running_state.watcher_disabled_nodes) ``` 通过这些优化，可以使代码更简洁、可读性更高，并且提高执行效率。
