well, what games do not work for you?

Archangel1235 · March 10, 2020, 7:10am

any help from Khadas team will be appreciated

playstation2 emulator

Archangel1235 · March 10, 2020, 8:54am

Ps2 emulator will struggle even in Snapdragon 845

Electr1 · March 11, 2020, 10:36am

What a coincidence !
I thought I was the only person who wanted to play video games on a professional Android/Linux development board.

There is EMUELEC that works pretty well on VIM3

superceleron · March 11, 2020, 3:00pm

you guys can’t achieve it by messing with the DT(been there done that long long a go)… all Amlogic cpu freq are locked in the hw blob…
Unless you guys can get the unlocked blobs from amlogic, you stuck!
Max you can do is play with mem clocks and timings…

EMUELEC still can’t run PSP GOD OF WAR smoothly

So, is there a possibility of RK3588 overclocking?

Archangel1235 · March 11, 2020, 3:32pm

Where did you get that info…?

superceleron · March 11, 2020, 5:12pm

let say a bird said it to me…
anyway… if you search hard enough you will find that info, since is public from other older chips.

Archangel1235 · March 11, 2020, 5:27pm

Only one forum says that…

Can anyone from Khadas confirm this…?

Spikerguy · March 11, 2020, 9:47pm

If @superceleron have said it that means its true.

As he works closely with Amlogic and I would believe him it.

Archangel1235 · March 12, 2020, 5:54am

Bummer Thanks

Would be helful if khadas team can get that bin file

Electr1 · March 12, 2020, 2:44pm

It seems that the blob for overclocking was obtained by the company Hardkernel in overclocking the Amlogic S905 in one of their SBC’s. Khadas could try to communicate with Amlogic to get the required files.

links to where I got the info,

xlazom00 · March 17, 2020, 11:27pm

I added two freq 2.3 and 2.4GHz to dtsi
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/arch/arm64/boot/dts/amlogic/meson-g12b-a311d.dtsi?h=v5.5.9#n144

and nothing show up in cpufreq-info
So are there any options to enable overclocking ?

Archangel1235 · March 18, 2020, 8:43am

this is not the file to edited…

you will have to edit the file " kvim3_linux.dts"

also note while changing the freq I think voltage should be left unchanged as max voltage to A311D cpu is 1.03 volts

As of now all these attempts yields no result.

xlazom00 · March 18, 2020, 9:48am

I want to use mainline kernel

Electr1 · May 19, 2020, 9:48am

hi,
I uncompiled the .dts file for the A311D,

what do i do now ?

Can anyone at khadas help,
@Gouwa @tsangyoujun can you guys help us with overclocking
