Bug: cpu freq parse failure

[undefined-moe]

Describe the bug On VMware workstation pro 17.5 (client system Ubuntu 23.10 Kernel 6.7.0-rc3), systeminfo.cpu() failed to parse cpu speed.

node -e "require('systeminformation').cpu().then(console.log)" returns:

refer to https://github.com/sebhildebrandt/systeminformation/blob/5c5efe269eb0eedcb985a3e4be14652e37e75a3b/lib/cpu.js#L735 it parses first occured Model name while in this case that information's in BIOS Model name.

This bug also work in Debian 12 with kernal 6.1.0-17-amd64

Hi @undefined-moe , @Lixuannan , I will have a look at it!

@Lixuannan : can you provide the output of the following on your machine?

lscpu
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
dmidecode –t 4
cat /proc/cpuinfo

[sebhildebrandt]

@undefined-moe ... just to be sure ... your Ubuntu 23.10 is running in VMWare as a client host system (so on an virtual machine), right? On the host itself all is fine? But inside the VMware client we have this behavior?

[undefined-moe]

Can't confirm. I'm just forwarding this bug report from the original issue :(

but it seems that on lots of environments the cpu freq is in BIOS Model name after Model name line.

@undefined-moe @Lixuannan ... should be fixed, can you test this? Version 5.21.23 just released.
