 |
|
Hi,
I tried to build a Kernel with my own configuration. After a while every thing seems to work correct. But I found a difference between my Kernel and the Kernel used by the systemrescuecd from sysresccd.org (both Kernel-2.6.36-x86_64).
When I type lspci -v in a shell on my system I get:
| Code: |
00:1c.0 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 1 (rev 03) (prog-if 00 [Normal decode])
Flags: bus master, fast devsel, latency 0
Bus: primary=00, secondary=02, subordinate=02, sec-latency=0
I/O behind bridge: 00003000-00003fff
Memory behind bridge: f6100000-f61fffff
Prefetchable memory behind bridge: 00000000c0000000-00000000c01fffff

with the syresccd I get:
| Code: |

Kernel driver in use: pcieport
Kernel modules: shpchp
|
I wondered about the difference "Kernel modules: shpchp". I also included this driver in my Kernel but it doesn't use it. I searched the web and this forum but can't find any solution. What am I doing wrong?

Thank you for your help |

modprobe shpchp ? You have it enabled in your .config (it's the driver for PCI/PCIe hotplug,
which you probably will never even need). |

I have tried modprobe shpchp, but it doesn't work, because I've built this driver into the Kernel. So I tried building it as a module and now I get it displayed with lspci -v.
But why haven't lspci shown shpchp before? |
