我刚刚“完成”了我的新申请。当我用我的低成本平板电脑(有很多可用内存)测试它时,一切似乎都很好。但是如果我有时在我的 HTC 手机上运行它,我会在日志窗口中看到一条消息:

11-04 22:11:34.570: D/memalloc(16419): /dev/pmem: Unmapping buffer base:0x527a0000 size:6144000 offset:4608000

我很难找到对此消息的解释。谁能解释一下?

最佳答案

找到这个:

The pmem driver is used to manage large (1-16+MB) physically contiguous regions of memory shared between userspace and kernel drivers (dsp, gpu, etc). It was written specifically to deal with hardware limitations of the MSM7201A, but could be used for other chipsets as well. For now, you're safe to turn it off on x86.
