lshw中无人认领的设备

Question

我在我的计算机中添加了一个带有 2 个 USB3 端口和 2 个 sata3 端口的 PCI Express 控制卡。（http://www.ldlc.be/fiche/PB00121886.html）。

USB 端口工作正常，但插入 sata 端口的 HDD 未出现在设备中。

我运行了 lshw，这里是关于 pci 卡的结果：

*-pci:1

似乎 Unclaimed IDE 是罪魁祸首，它无人认领是因为系统找不到驱动程序。我如何才能找到使该 ide 部分工作所需的驱动程序？

到目前为止，我对 PEX 8604 的谷歌搜索几乎没有返回任何关于 linux 驱动程序的信息。

Answer 1

我找到了解决办法。该设备无人认领，因为内核无法正确识别该设备。

使用内核 3.5，该设备列出如下：

*-ide UNCLAIMED
               description: IDE interface
               product: ASM1061 SATA IDE Controller
               vendor: ASMedia Technology Inc.

               version: 01
               width: 32 bits
               clock: 33MHz
               capabilities: ide msi pm pciexpress cap_list
               configuration: latency=0
               resources: ioport:7000(size=8) ioport:7400(size=4) ioport:7800(size=8) ioport:7c00(size=4) ioport:8000(size=16) memory:d6100000-d6100

但它仍然无人认领。

在搜索设备 [1b21:0611] 时，我在内核邮件列表中发现了一篇关于它的帖子。它告诉内核没有将设备正确识别为 ahci 设备，并向内核提出补丁。

我将补丁应用到内核 3.5 的源代码并重新编译，它现在可以工作了。有关信息，该补丁包含在 3.6 及更高版本的内核中。
