I need to ask you for advice. I have reviewed the ufs_mem_hc of many
devices and found that all of them use QCOM_ICC_TAG_ALWAYS for their
interconnects cpu path. Why do I need to use QCOM_ICC_TAG_ACTIVE_ONLY here?

The required-opps here corresponds to opp-200000000 in the opp_table
below. Similarly, I referred to sm8550.dtsi, whose required-opps also
corresponds to the opp table.

I have reviewed the ufs_mem_hc of many devices and found that all of them use QCOM_ICC_TAG_ALWAYS for their interconnects cpu path. Why do I need to use QCOM_ICC_TAG_ACTIVE_ONLY here? QCOM_ICC_TAG_ACTIVE_ONLY instructs RPMh to shut off the interconnect path when the CPUs go offline (without OS intervention) to save power and bus bandwidth. It's the natural choice for paths that directly connect hardware to the CPU, as nothing else should be accessing these ports. Currently, many platforms do not set that, because nobody cared enough to point it out :( One day when we lay some more groundwork on the suspend side, I'll send a treewide fixup. >> >>> + interconnect-names = "ufs-ddr", >>> + "cpu-ufs"; >>> + >>> + power-domains = <&gcc UFS_PHY_GDSC>; >>> + required-opps = <&rpmhpd_opp_nom>; >> >> this contradicts the levels in the OPP table: > The required-opps here corresponds to opp-200000000 in the opp_table below. Similarly, I referred to sm8550.dtsi, whose required-opps also corresponds to the opp table. What I'm saying is, specifying required-opps of NOM here will make VDD_CX always stay at >= NOM, because the vote is max()-ed Konrad
