Dmesg to a log file and read afterwards.
[Atrix 4G Android Development] ghost_og:
Same here.:D I apologize if I came off condescending in that last post. Not my intent at all. :o

My highlights in red. My deltas were referring to the difference from the prior frequency.

In this instance I'm assuming that using -500 doesn't crash because the DVFS kicks in and automatically adjusts to an acceptable voltage since the change would be:

1050mV <----912MHz

650mV (Delta 400. DVFS changes to acceptable mV = no crash. 1050mV?1150mv?)

????mV (Delta ?? But obviously stable)

????mV (Delta ?? But obviously stable)

My question here would be, what does the DVFS adjust to? The stock value, or the bare minimum needed to be stable? (I put question marks for the final ones since we're not sure what values are being used). That would help to determine why your next test crashes.

For these 2 tests did you only change the one frequency like above? Or did you leave the -500 for 1000MHz and start working your way up?

Thank you for the feedback and suggestions. :) Maybe this is why faux mentioned how much of pain DVFS was to figure out.

*EDIT BELOW*

After hashing this out I realize why my assumption that these would get changed is wrong in this case. Those values wouldn't get adjusted at all because the crash would most likely get triggered by this:

850mv

900mv

950mv

Even though that step is only a difference of 50, it is still -150mv below the stock value, which would most likely be too low for that frequency. So it makes perfect sense why 1050/1150 wouldn't work.
[Atrix 4G Android Development] jokersax11:
The kernel uses a cpcap regulator table. To overclock, higher voltage had to be entered +25mv at a time. I know the system boots at stock voltage then changes to the adjusted values(dont know why or how yet), the boot up dmesg log is in data/var/log/dmesg. Im curious if any voltage under 750 is registered as its not in the table. Unless the table is loaded once during boot and a separate system handles changes. Everyone is super happy at the photon forums so no one cares to get involved in kernel evolution.
[Atrix 4G Android Development] jokersax11:
If anyone reads that log on the atrix could you tell me if the ram is lpddr2 like the photon
[Atrix 4G Android Development] ghost_og:
I went to pull this but I do not have data/var/log/dmesg. In fact when I navigate to /data there is no /var folder at all. Ideas?
[Atrix 4G Android Development] jokersax11:
Use root explorer
[Atrix 4G Android Development] ghost_og:
Sorry, it wasn't that there were no folders in /data, just that /var wasn't one of them.

I found this under /sys/ram/info:

Elpida-50nm:LPDDR2:x16:S4:1GB

Hope that helps.
[Atrix 4G Android Development] jokersax11:
Yes dear lord that helps. I was going nuts as to why i couldnt reach 333 like you guys

Hynix-54nm:LPDDR2:x16:S4:1GB

Thats the photon
[Atrix 4G Android Development] jokersax11:
Btw if it helps with testing the runtime volt table is /sys/devices/system/cpu/cpu0/cpufreq/frequency_voltage_table
[Atrix 4G Android Development] sms2000:
Hi everyone!

I'd ask for help applying this kernel.

What I was there are:

- Atrix 860 from Orange updated to 2.3.4 4.5.2A-74_OLE-33 (Orange Israel, I presume).

- Rooted with BL unlocked and memory fix applied.

- Till this point everything was perfect.

-----------------------------

- I tried to install this kernel [Unified GB Kernel Version 0.2.2r_2 @ 1.45 GHz] and my phone was soft bricked.

- I failed to understand properly what cache I need to clear and why?

- The phone self-rebooted constantly (soft-brick?)

- I had to use RSDLite to back to 2.3.4 original and re-root.

What exactly I did wrong? Not clearing cache (which one)?

Or using wrong kernel?

Thanks.
[Atrix 4G Android Development] turl1:
The Atrix RAM doesn't get OCed though, it might just be that :) I put a 600 clock for the lulz and it still booted; performance was unchanged.

PS: RAM Elpida-50nm:LPDDR2:x16:S4:1GB
[Atrix 4G Android Development] ghost_og:
Just wanted to give a small update on some of the tests I've been trying. I can incrementally get to -500uv for all frequencies starting with 216MHz, stress testing along the way. When I check the above table, the values are being applied.

Strange thing is if I set them all at -500 then apply at once, instant freeze.

If all are at stock, and I drop 1000MHz by -500, instant freeze.

I rebooted and incremented back up to -500 for all frequencies again. I then started adding 100mV to the 1000MHz frequency only:

UV @ -400 and -300 were fine

UV @ -200 caused a crash

This was with all of the lower frequencies still at -500.

So Newbleeto is right, and the voltage threshold doesn't quite work they way we thought it did. It seems in some instances values are being ignored, and in others they're being respected.
[Atrix 4G Android Development] Newbleeto:
I can confirm the gradual increment working versus the sudden change to -500 mV causing an instant crash.

Here are my undervolt values and the screenshot of the table :

Because the table shows both values, I'm not sure the undervolt is being applied. Also, it is very extreme, so I have some doubts.

Anyhow, it does seem the undervolt limits work differently then previously thought. Anyone can make proper sense out of this?
[Atrix 4G Android Development] faux123:
wow, what's with the sudden interest in UV?

I am still out on travels (and no, it's NOT a vacation, though I wish it is).

Anyways, tonight is the first night I actually have time to catch up on the forum posts. As I stated on my tweet and posts before, I recently bought a lapdock from a black Friday sale just for Webtop debugging... so once I get back, I will start to look at the webtop issues and get it out of the way. this problem has been around for a while because I had no way of testing it myself (can't find my cable, so lapdock is my expensive "cable replacement" :p)
[Atrix 4G Android Development] krkeegan:
First, the lapdock is pretty cool, I think you will enjoy having it. Were you able to get a $50 one from ATT?

Second, to offset your investment and to say thank you I sent $20 your way. 14L99032YX320950X

Thanks again, let me know if you need any more debugging help.
[Atrix 4G Android Development] cjrhoades:
Awesome! I just got a $50 lapdock from AT&T's sale but had to revert back to the stock Gingerbread kernel because it kept getting stuck at 1GHz. Hopefully you can fix that now :)
[Atrix 4G Android Development] Gutterball:
Hey faux Your work is great! Quick question though. I'm trying to figure out why some games freeze on your kernels?? 2 games in particular that do are zombie rider and turbo grannies both made by the same company too. If I install darkside lets say without a kernel these games play fine but if I flash your kernels over the top they both freeze.

So I tried a different OC kernel (kholks) at 1.4 ghz and the games didn't freeze and played fine. Do you have any idea why I get this on some games?? And once again thanks for all your work!

[Atrix 4G Android Development] bapaogoreng:
Hi, I've searched this thread for any finger print scanner related problem, but can't found it. So I think I have to mention this...

With version 0.2.2 my finger print scanner has a delay for about 1-2 seconds before it responds to my swipe when unlocking the phone after screen on. This only happens if the phone has been in stand by mode (screen off) for several minutes, when I try to turn off the screen to lock and turn it on again to unlock within a minute or less, the finger print scanner works with no delay.

There's another user who posted the same problem with Clemsyn's kernel which is based on this kernel. I hope I'm not the only one with this problem here.

Anyway, thanks faux for developing this :D
[Atrix 4G Android Development] CaelanT:
That's normal with this kernel. The previous kernel version for whatever reason had no lag on the FP when waking the phone.
[Atrix 4G Android Development] sms2000:
Does it mean the latest kernel is buggy? Any fixes planned?
[Atrix 4G Android Development] bapaogoreng:
Well, you may call it buggy, but I call it "delay" :D

I hope faux will fix this with the next release.
[Atrix 4G Android Development] sms2000:
That's what I mean really.
[Atrix 4G Android Development] faux123:

How can I drop back to the stock kernel without full reflash?

I understand that "INTL mbr_d00 original Kernel Version" requires EXT3 only and my /system is EXT4 after I installed OC kernel.

Is any procedure exists? Or I have to flash the SBF, reapply again "root" and "unlock"? Brrrr....

Thanks.

P.S. I have multiple issues with OC kernels even downclocked to 1GHz. System is unstable, reboots irregulary...
[Atrix 4G Android Development] newalopez:
Faux sorry to bother, but the bug that we can't play PES 2012, NFS Shift, and some more games with this kernel, can you check it? I can only play those games with the INTL stock kernel, even I have something around 40mb more ram with stock.

Other thing, stock kernel doesn't have the delay on fingerprint scan to be ready after screen on.

Let me know what else I can do.
[Atrix 4G Android Development] stewartsoda:
I've been running this for the last 5 hours or so and it seems rock solid. My only comment is it looks like the OC limit set by SetCPU doesn't always stick. If I put it at 1.3 GHz max and watch the "Time in each state" info view the 1.45 GHz count continues to go up, albeit at a reduced rate.

I don't know if this really matters, because with a -75 mV undervolt across the board it still looks rock solid.

I did get stuck in an overheating bootloop when I first booted before UV, though.
[Atrix 4G Android Development] sms2000:
I found that my problems with frequent reboots were easy cured with Factory Reset.

Now the stock Faux kernel works well.

Is there any appropriate procedure to be run before/after kernel update that leaves the phone stable without Factory Reset needed?

Thanks.
[Atrix 4G Android Development] Filipeknot:
Try with webtop2sd! It will use 100% of CPU!
[Atrix 4G Android Development] aaron.a:
i used this for a while with the cm7 pre beta and i had some pretty bad over heating when i maxed the clock and browsed the web, or watched videos.

i crashed the phone several times and would need to wait for it to cool down before i could get past the boot animation. i guess the hardware survived tho.

this is expected behavior when you push the phone that hard right? i mean it got hot enough that you wouldn't want to squeeze it. i'm sticking to underclocking for battery conservation for a while. lol
[Atrix 4G Android Development] Nipit:
Please release soon 0.23 CM7 kernel for beta testing ;)
[Atrix 4G Android Development] Frankzor:
I just tried webtop with webtop2sd on faux123 stock gb kernel version 023 1.4gHz. With zram enabled, I sure don't see RAM filled to the brim on webtop, even with 8 linux apps on. CPU stays clocked on max UNTIL I went down to 5 linux apps. Nice work faux123!

My only gripe is the fact that my atrix soft resets a lot more now lol. Can anyone share the UV settings for OC 1.4 please ? (even though I know each device is unique in this regard) Mine is set to - 50 mV everywhere and it does hang out a lot in webtop, but not in regular Android

@ filipeknot

Can you tell me what linux apps do you run on webtop?
[Atrix 4G Android Development] faux123:
with webtop, the cpu load will be heavier therefore too much under volting may cause instability. I was able to run my phone perfectly at -100 uv across the board without webtop but with webtop I can only do -75 uv across. I am happy with -75 uv across.

remember not all phones are created equal... YMMV
[Atrix 4G Android Development] faux123:
cm7 webtop will be a while. there are lots of hacks involved motorola did to get webtop working with their rom, so the same amount of hacks will need to be done in order to get webtop working on cm7.

Hi there,

Little off topic, i am on CM7 Weekly build, 2011-12-10 and using ur 2.2 stock frequency CM7 kernel. every thing is working fine but every now and then phone freeze and reboots.

I was doing some UV -50,-75,-100,-125 and so on till -200 (this worked fine for Atrix Ba2tF build but not for Weekly build, 2011-12-10 miner under volting cause instability)

I am now using ROM with out any UV and seams to be fine, will post the results and report if any thing odd happens.

P.S: tell me what happens if i am using task killer app and it kills setcpu, would that be the cause of the problem (just a thought)
[Atrix 4G Android Development] newalopez:

[Atrix 4G Android Development] Notorious544d:
By gaming issues, does it also fix the GPU OC which apparently wasn't working properly in previous builds?

Judging by a large increase in 3D Quadrant (750 to 695), I really hope so!

And lastly, will you be considering an option where we can adjust frequency tables?

Thanks for your work!! It's great to see that despite so many device kernels you make, you always come back to Atrix despite it not being as good and powerful as the other devices you own. That's truly respected.

1.45 is quite extreme. And baring in mind that the MAX (safety level) is 1400mV, and 1.45 usually gets UV'ed down to 1300mV, I think even 1.6 won't be possible.

But 1.5Ghz, maybe... ;)

i am having problems since ver 021 with all music apps such as power amp and double twist both being real time. The problem is related to crappy and broken sound.

i installed pure stock kernel today ( rom Dark Side 4.0 ) and the problem is not there either.

could you please take a look at the changes you made as of 021 and or elaborate on the problem i am describing?

thanks

--------

BTW the problem i am describing in previous post also appear in a "child" kernel based on your 022

My previous post must be clarified:

I was checking your changelog and the major changes where implemented in 022. The problem I was describing does not appear in 021 nor in pure stock kernel.

The ROMs used for testing are HomeBase and DarkSide. Both behave the same with the music apps and the various kernel versions mentioned in this post as well in your "child" kernel based on your 022. (crappy/choppy sound as of ver 022)

[Atrix 4G Android Development] Swiftks:
I'd suggest you set all voltage back to normal, uncheck start at boot. Then download stability checker from market. Then take each frequency, 1 at a time, start w/ -25 undervolt with the highest frequency, set your Max and Min to that frequency only, then use the stability test app. If its ok, then move in to -50, and so forth and so on, until you get a reboot; then you know to go back to the voltage step before that, and set it there. Then move on to the next frequency step, and make sure to set Min & Max to that frequency, and test it the same way. Once you have tested every frequency, then select to start at boot.

Forgive me if this has been asked before but I couldn't find any information in this thread.

How do we increase the size of swap/zram partitions? Having zram available has done wonderful things for webtop but I use a lot of tabs when browsing and will eat through the available swap space fairly quickly.
