我有运行 Debian Wheezy 的 VMware 虚拟机。我编译了自己的内核3.14。我注意到dmesg
充斥着消息pci BAR 7: can't assign io (size 0x1000)
。
我不知道这些消息意味着什么。虚拟机似乎运行正常,我没有看到任何问题。尽管如此,我还是对这些错误消息感到困扰,如果我能摆脱它们,我会很高兴。
有人可以解释一下吗
1)这些消息的含义是什么
2)我怎样才能摆脱它们

实际上,dmesg 包含超过 550 行与 PCI 相关的(调试)日志。我已经粘贴了相关部分这里
我怎样才能摆脱这些日志?
它们没有用,只是淹没了我的日志
答案1
在我看来,尽管您是在虚拟机中运行,但您似乎遇到了与 PCI 总线数据吞吐量的内存分配相关的错误。虽然我不熟悉 VMWare,但我怀疑可能存在 PCI 模拟或内存分配相关的设置,您可以调整来修复它。
本文末尾引用的论坛主题表明,可以通过禁用 ACPI 来解决类似的问题,但我不能保证所述主题的准确性。
我怀疑(尽管我没有任何信息支持这一点,所以请持保留态度)它可能与您正在模拟的架构有关。如果您正在模拟 32 位 x86,我可能建议尝试模拟同一软件的 64 位版本,并测试它是否也出现在那里。
至于删除日志,我相信可以使用 轻松完成dmesg -C
,或者(如果您想自动化)设置一个 cron 任务来每小时执行上述任务。

答案2
它与 PCI 总线数据吞吐量的内存分配有关。请通过 vSphere Client 启用 vSwitch 中的流量调整选项。
我已经尝试过这个并且对我来说效果很好。
