RK3368 04/2017 True Octacore Firmware

[Shomari]

... the little core frequencies in the 'regular' overclocked builds were explained in here somewhere, and on 4PDA. With the little cluster left stock enabled as factory set, it acts differently upon the power regulator, and it's difficult to raise the frequencies above 1512 (or whatever I set it to, but it actually can go a bit higher than 1200, if anyone were to push it) while the big cluster is at 1608. That's an issue only with the builds with the fixed power menu, but it's still a significant overclock for both clusters and provides significant performance boosts.

In short, the power regulator needs to be able 'to see' the Little cluster in order to control the power states. When I bypass the cluster structure to enable the cpu hack, I disable the Little cluster and trick the system into seeing only 8 cores in one big. cluster, in effect leaving it 'blind' in terms of controlling the power states. As you would guess, there's no documentation for doing such a thing in any part of this process, so it's no small effort to port the entire power management over to the 'true octacore' structure, for what I consider to be small gain.

The 'true octacore' builds are different. All cores run at 1608 and I tuned the mechanism very carefully to ensure both stability and performance over the last 7 months. I stopped caring about the power menu bug mostly for the same reason I started the project in the first place - it's a TV box. The ability to reboot and use the power menu is not crucial - to me.

I wish the bug wasn't there, because it's still a bug, but I don't have the time/effort right not to chase it down again.

OK. I check for AnTuTu 6.3.3 and will test it again. Aptoide has only 6.1. I don't wanna use a google account for testing. So I didn't check there.

Ha ha ha silly Ugoos users.

Yeah you got it, you offer your normal android box version and I offer a ATV version. So for both taste a solution.

I will send you a link tomorrow, now its time for other things.

[Shomari]

See, but I think we should do a 'joint' version, too. I'm telling you, we can get an Android TV version with some might good performance.

Plus, what about a Marshmallow version? People keep asking...

AnTuTu Video Tester on my full firmware 'true octacore' build. And Bonsai @ 1080p

[Shomari]

If anybody installs the full 'true octacore' firmware, and can run anTuTu 6.3.3, I'm curious what results you're getting. Especially if it's anything under 47,000.

Just curiosity...

By the way, cOOLio Geekbench won't run on any of my firmware builds do to segfaults, it'll crash before completing when it gets to the 76% point, where all cores are punched. It's a limitation in the app but also the limits of the a53, it was never intended by ARM that it be ran with eight cores in a single cluster. So we're lucky we even get this much fun out of it..

Top single core performance result with RK3368 in the list is mine though, and single core is what really matters. You can actually see, if you know where to look, where I started with my builds using Geekbench, and how far up I've raised the performance through looking at the results.

Even with anTuTu, my Z4 I use for testing scores 34K from stock. All software changes and it's now 14K better. We're still going though..

HI ,

Can you please explain why Ugoos Users are silly ???

U use Ugoos Roms too , u only modifiy them , isnˋt that true ??? !!!

So without Ugoos your Box will be on STockBullshitFW . So we silly ???

good night

...whoa, I don't think he meant it all that seriously. Either way, no need to start a fight over a (probably misinterpreted) joke.

I'd rather just keep it fun and interesting.

[Shomari]

here's a full Z4 port in two variations. One is the true octacore kind: http://ge.tt/9MIlMgj2

The second is the overclocked kind but with the power menu fix, big cores running at 1608 max but with separate clusters: http://ge.tt/7GKnMgj2

You won't lose any data flashing the images in the archives provided. For each variation flash both the kernel and resource in the archive.

These files are targeted for the Z4, all your components will function correctly.

These will also work for devices with AP6330 wireless chips.

Link to full update (since I haven't updated OP it keeps getting buried)

https://mega.nz/#!bNwFDBjS!4mfrgm8C6...q2X8Wy1h2u3YC0

AP6330 support in quoted links above. Images in archive are intended for use with full firmware. You can mix and match with other firmware if you'd like, but stability and performance are not guaranteed, and I can't/won't debug issues arising from mixing and matching with other firmwares. The combinations would be endless, and the issues and environments too difficult to reproduce. It's time intensive enough to debug issues within my own very familiar builds at times. I'm sure you understand..

Flashed the resource image. Flashed successfully, first boot went to screen with penguins on top and E: failed to mount /external_sd (No such device) below that Formatting /data....
then green screen. Next boot stopped at Formatting /data...

Shomari,

Flashed resource image again and still the same result. Let it sit for awhile but still not booting.

Hi Shomari ,

a Joke , how can you know that Shomari , you are not him , or ???

It is "silly" to say UgoosUsers are silly . I never want to start a fight .

He profits from Ugoos , without Ugoos his Box is ... , and what will Ugoos say to that ???

nice Day

[trebor]

This to work on Zidoo x6? something to do this week end and possible Z68 ?
Thanks

I don't know, neither do you. The same way you seemingly urge caution - or flat out dismissal and doubt - about my assertion that it was a joke, a quip made in harmless jest, is the same way I say don't be so quick to bring your guns to the saloon for a shootout at high noon. *Figures of speech. This is a plain text forum where we communicate in words. A flawed medium in many ways.

But I can interpret from the available context, and general disposition of his typical posts that it's not very likely to be intended as malicious or inflammatory.

You can disagree.

I simply said I'd rather chill, but in different terms.

I don't speak for that poster or any other, so no, I'm not 'him'. I simply reminded everyone that text doesn't always convey sarcasm, wit, humor effectively. This is especially true with non native speakers.

I have nothing else to say about it.

Suit yourself.

Shomari,

I'll post something for you in a couple days as soon as I get a little time. I have some ideas.

[gefattern]

Hi Shomari ,

i know that you not speak for him , i asked him , you answered ,

and "suit yourself" is not sarcasm ???

we will see

suit ....
