AOSS not entering sleep mode leads to a (apparently significant) increase in S3 power consumption, on trogdor and herobrine it prevents the system from staying suspended, because the embedded controller detect the condition and wakes the sytem up again. Testing is slightly involved, since unfortunately this is not the only issue in v6.2-rcN that impacts AOSS sleep. To reach AOSS sleep you also have to revert this commit: 3a39049f88e4 soc: qcom: rpmhpd: Use highest corner until sync_state And apply something like the diff below (or enable the bwmon driver). On a trogdor device you will see something like this when AOSS doesn't enter sleep mode during system suspend: [ 32.882869] EC detected sleep transition timeout.

Thanks for the report. To be sure the issue doesn't fall through the cracks unnoticed, I'm adding it to regzbot, the Linux kernel regression tracking bot: #regzbot ^introduced a837e5161cfffbb32 #regzbot title meida: venus: firmware: AOSS doesn't seel anymore on at least sc7180 and sc7280 #regzbot ignore-activity This isn't a regression? This issue or a fix for it are already discussed somewhere else? It was fixed already? You want to clarify when the regression started to happen? Or point out I got the title or something else totally wrong? Then just reply and tell me -- ideally while also telling regzbot about it, as explained by the page listed in the footer of this mail. Developers: When fixing the issue, remember to add 'Link:' tags pointing to the report (the parent of this mail). See page linked in footer for details.

A change or fix related to the regression discussed in this thread was posted or applied, but it did not use a Link: tag to point to the report, as Linus and the documentation call for.
