10:46 <wctrl[m]> oops apparently my message wasn't sent due to missing registration; Is there any requirements for DVFS with mali bifrost besides opp table on the mediatek SoC? clock rate is always the same for me

10:57 <robmur01> IIRC, some MTK SoCs were fiddly because they have multiple regulators, where the generic OPP code only supports one

10:58 <robmur01> however if you do have the appropriate regulator-coupling trickery and an appropriate OPP table with only one set of voltages then I believe that should work, provided you have all the relevant devfreq stuff enabled in your kernel

10:59 <wctrl[m]> yup, I've enabled regulators and power domains and the gpu is successfully probed, however the clock is always the same (probably programmed by the bootloader)... (full message at <https://matrix.org/oftc/media/v1/media/download/AcBZSq_MYBiOw9dXA6lpqGuboHa_7mHHNbBclXOMCBe-qS-eIf7TjxnMVUa5AxTZ3uCHgXnNVo3Mo6bAR9R5WVlCeYNvCAJgAG1hdHJpeC5vcmcvV0t2QmtqZ3dRU3pUblpFaFhvaVV0ZlJ5>)

11:04 <robmur01> what if you try the userspace governor - can it change OPPs OK manually?

11:04 <wctrl[m]> the SoC is mt6768 (we're not in upstream yet): https://github.com/mt6768-mainline/linux/blob/528af8be627e52952453dd63004a482ab3f413eb/arch/arm64/boot/dts/mediatek/mt6768.dtsi#L704 + https://github.com/mt6768-mainline/linux/blob/528af8be627e52952453dd63004a482ab3f413eb/arch/arm64/boot/dts/mediatek/mt6769z-xiaomi-merlin.dts#L134

11:11 <wctrl[m]> hmm only powersave drops to minimal frequency

11:11 <wctrl[m]> lemme check if it'll heat like before

11:12 <robmur01> yeah, nothing looks particularly wrong there - at this point I'd consider something at the clock driver end to be the most likely suspect, especially if the other governors can't change it as expected either

11:16 <wctrl[m]> hm well the clock changes only with performance/powersave governors, and even on 300mhz it's pretty hot

11:17 <wctrl[m]> maybe I messed up voltages

16:39 <wctrl[m]> hmm yeah sram voltage is bigger than expected (while freq is 300mhz the voltage is for 768mhz), ideas how i can set voltage map between coupled regulators?

19:09 <alyssa> Lol

19:09 <alyssa> oops

19:09 <alyssa> wrong buffer
