PCIE1 is disabled in plugin manager on NX module?

Mar 04, 2024

In tegra194-plugin-manager-p3668.dtsi, I see:


		fragement-tegra-pcie-c4-dis {
ids = ">=3449-0000-000";
override@0 {
target = <&{/pcie@14160000}>;
_overlay_ {
status = "disabled";
};
};
};

But in tegra194-p3668-common.dtsi:


	pcie@14160000 {
status = "okay";

nvidia,pex-wake = <&tegra_main_gpio TEGRA194_MAIN_GPIO(L, 2)
GPIO_ACTIVE_HIGH>;
vddio-pex-ctl-supply = <&p3668_spmic_sd3>;
nvidia,disable-aspm-states = <0xf>;
nvidia,enable-power-down;
nvidia,max-speed =
;

num-lanes =

;
phys = <&p2u_11>;
phy-names = "pcie-p2u-0";
};


It seems the two are conflict with each other, which one will have higher priority? Or they work at different stage? Such as PCIE1 is disabled at CBoot stage, but enabled latter?


Thanks.
