在这个程序中,以这种方式执行缓冲区处理并不会显著影响执行时间,而对于某些数据集,可能有消极影响。
In this particular program, doing buffer handling in this way does not affect the execution time significantly, and in some data sets, affects it negatively.
对于垂直方向上的每个空格来说,管理程序都会采用 DMA 方式将自己的缓冲区读到 GPU 的内存中,然后将 GPU 的可视页刷新为与垂直空格信号同步的数据。
Every vertical blank, the hypervisor DMAs this buffer to the GPU memory, and then flips the GPU's visible page to the new data synchronously with the vertical blank signal.
如果采用异步写日志的方式,那么在发生错误时,可能会丢失多条审计记录,因为这些审计记录在被写到磁盘之前都在缓冲区中。
If an error occurs when using asynchronous log writing, multiple audit records may be lost because they are buffered before being written to disk.
