|
lshw on my Dell laptop is showing different results between being run from sysresccd and from my own kernel configuration. Version of lshw is B.02.16 in both cases.
From my own configuration it's missing version: 6.10.9 and serial : xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xxxx and it only displays one cpu but none of the logical cpu. | lshw -class cpu from my own kernel configuration: | *-cpu
description: CPU

Which is the kernel option I have to enable to get the full display for cpu? Any help is much appreciated.

cat /proc/cpuinfo might be more informative.

Probably the msr or cpuid driver. |

It doesn't show the difference as seen with lshw. Here it is from my own configuration: cat /proc/cpuinfo and this is the difference.

Both are enabled | grep -E 'MSI|CPUID' .config: | CONFIG_GENERIC_MSI_IRQ=y
CONFIG_GENERIC_MSI_IRQ_DOMAIN=y
CONFIG_X86_CPUID=y
CONFIG_PCI_MSI=y
CONFIG_PCI_MSI_IRQ_DOMAIN=y
# CONFIG_MSI_LAPTOP is not set
# CONFIG_MSI_WMI is not set |
But there must be a reason why lshw shows it so diffetently. |

Uuh, misreading 
| grep MSR .config: | CONFIG_X86_DEBUGCTLMSR=y
CONFIG_X86_MSR=y
CONFIG_SCSI_ARCMSR=y |
The CONFIG_SCSI_ARCMSR was not enabled. But enabling it didn't help.
Some more ideas? Kernel .config is here.
(Think I'd better change the subject to "kernel config for i7-3740QM") |
