Hi Rajendra, After applying 2,3 and 4/5 patches on linaro-integration v5.8-rc2 I see below messages on db845: qcom-venus aa00000.video-codec: dev_pm_opp_set_rate: failed to find current OPP for freq 533000097 (-34) ^^^ This one is new. qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x30000 ^^^ and this message is annoying, can we make it pr_debug in rpmh?How annoyingly often do you see this message?I haven't gig deeply but on every driver pm_runtime_suspend (after applying Rajendra's patches). And I guess it comes after a call to dev_pm_opp_set_rate(dev, 0).
Or it might be when the driver is switching off opp_pmdomain.
IMO this is too often.quoted
Usually, this is an indication of bad system state either on remote processors in the SoC or in Linux itself. On a smooth sailing build you should not see this 'warning'.quoted
Would you be fine with moving this message to a pr_debug? Its currently a pr_info_ratelimited()I would rather not, moving this out of sight will mask a lot serious issues that otherwise bring attention to the developers. --Lina
