@fever_wits raise your concerns and potential contributions here and hopefully someone like minded will have a conversation, other than that look at past support for the board, and ping their attention here...

I don't know these boards at all, please take as an idea of experimentation, ordinarily you would have to look for differences in both the kernel (drivers) and dtb/dtsi (nodes), and where the opp tables are located. Best of luck!

Hello all, in that context it possible to extend the opp points up to 1800 Mhz in the table. The original idea was to incorporate "turbo mode" so that the changes can be made in user space by choice. I don't know how stable that might be overall, perhaps its now time to introduce those options for h616/8 boards. EDIT: If remembered correctly the GPU tables were available as patch, recently removed, perhaps I'm wrong, haven't as of now checked.

Oh well it was open source, would have liked to have had some discussions at the time to optimise though!

Hello All, Good to see all the progress. I wrote and tested the dvfs code for zero2, however did not have enough time spare to optimize as would have liked. Was a bit surprised that it was also adopted by others including the Vendor. There are two ways to incorporate dvfs, the xlate method which I decided to eventually adapt, and v2 opp points. xlate is as example. v2 you can use in tri-state, which avoids the driver patching. I haven't had interest to examine the h618 soc, however am assuming that variants should be addressed as it is supposed to be h616 similar.

Hello, Yes indeed all have found the same as @Gunjan Gupta. Particularly zero2 display engine, sun4i merge conflicts with megous patches were frustrating and had to work around that. Haven't been able to follow much lately, as probably already noted here, zero3 would be more attractive for today's applications. Although the soc is similar between boards, there are fundamental differences between board layouts, pmic etc wifi chip, I think. Haven't really paid much attention - so stand to be corrected .. more clarity at linux-sunxi. Guess, there would be some catches just copying over from zero2. Good luck!

Hello All, hope someone is fairing better with this. No real success in trying incremental steps. Adjusting regulators does not improve the situation at this point, was also entertaining the remote possibility of a floating pin. Am still trying a few ideas when have a moment.

Interesting - - - ran out of time, will have a look again tomorrow. https://github.com/orangepi-xunlong/linux-orangepi/tree/orange-pi-6.1-sun50iw9/drivers/net/wireless/uwe5622 Orange OS uses a "-DOTT_UWE" https://github.com/orangepi-xunlong/linux-orangepi/blob/3495b5ee0594566c9fed930b96b1cae90600412e/drivers/net/wireless/uwe5622/tty-sdio/Makefile#L4C1-L4C23

My initial thoughts were power issue, as alluded above, and had noted comparing orangepi-linux, mmc1 aliases present in dts. Both the dcdca (vdd-cpu) and dcdcc (vdd-sys-gpu) regulators are set higher than the manual recommends (orangpi-linux). Busy testing the above, as for the driver very much not an expert there.

Right thanks, @mantouboji appreciated, checking possible issues with cpufreq and ths. will dig in a bit over weekend to help.

@mantouboji could you please let me know if sun50i_cpufreq_nvmem is loading? dmesg | grep cpu*

That looks correct and what I would have tested.

Refer as above

Hello all, @Gunjan Gupta thank you for your tireless work on all things Armbian. I know we had brief discussion about 'trying wifi' for zero2, the main issues before were modules not compiling. Has any device tree specific work been done for the modern kernels? (Not that I last seen). The latest WIP Sunxi PR might be the time to start testing this, I will try to set some time aside this coming weekend, when going through the PR to test. I do have other pr's in staging for zero2, but cant promise any result. Best, Alistair
