How to add kernel parameter?

nguyentuan_k58h — Tue, 28 Apr 2020 03:37:03 GMT

Hi experts,

I want to use the on-chip board Wifi QCA6174 of IMX8M Quad Evk Kit. I'm using yocto to build my distro fsl-imx-xwayland, kernel 4.9.88-2.0.0 (rocko)

Following release notes document "For i.MX 8MQuad, it needs to add kernel parameter
"pci=nomsi" to support Murata 1CQ Wi-Fi". But i didn't find the way to add it.

Can you tell me how I can solve this problem and the steps for using the wlan chip QCA6174? Thank you.

Best regards,

Hi Tuan

this is general linux parameter and one can try to use it in the same way as

described in Table 10. Common kernel boot parameters. QCA6174 is described in

sect.4.12 Wi-Fi QCA6174 Linux Manual in Linux 4.9.88_2.0.0 BSP & Multimedia Codecs Documentation

Best regards
igor
