Description Chester Lin 2023-09-14 05:41:59 UTC

There are some kernel modules that need to be included in the initrd of the opensuse installer in order to boot Lenovo X13s, which is an arm64 laptop based on Qualcomm 8cx gen3 CPU.

The machine wouldn't boot without the following modules:

kernel/drivers/clk/qcom/clk-rpmh.ko
kernel/drivers/clk/qcom/dispcc-sc8280xp.ko
kernel/drivers/clk/qcom/gcc-sc8280xp.ko
kernel/drivers/remoteproc/qcom_q6v5.ko
kernel/drivers/remoteproc/qcom_q6v5_pas.ko

Another problem that I haven't figured out is that firmware blobs need to be loaded with the remoteproc drivers [qcom_q6v5 & qcom_q6v5] are not mentioned by driver code via the MODULE_FIRMWARE() macro, which means there's no firmware field in their modinfo. But they are mentioned in the devicetree[1] like this:


&remoteproc_adsp {
	firmware-name = "qcom/sc8280xp/LENOVO/21BX/qcadsp8280.mbn";

	status = "okay";
};

&remoteproc_nsp0 {
	firmware-name = "qcom/sc8280xp/LENOVO/21BX/qccdsp8280.mbn";

	status = "okay";
};

Could installation-images still fetch these two .mbn files into /lib/firmware?

Lenovo does not provide X13s ACPI support for Linux so hardware information is all from devicetree.

pr merged, thanks!

Sorry for reopening this bug.

There are a few more modules that need to be added since the original list is based on JeOS, and I found that the installer needs more modules included for X13s boot since the installer doesn't rely on an additional "root=" part to hold the other kernel modules, which means everything should be included in initrd ->parts/00_lib.
