Hey guys, did you know we can check how many tiler memory is used?

cat /sys/kernel/debug/tiler/map/4x1

With this, we could check the minimal free memory (for example, with some heavy 1080p files, or something like that), and reduce the reserved memory by that value. This way, we'd end up with completely safe bigmem values. I see about 41 MB free while recording 1080p on my WIP kernel, but I still need to test it further.

Also, could someone on a bigmem kernel post the output? I wonder how that looks now. And before anyone says, if we still have free tiler memory with a bigmem kernel, then it's performance must be equal or better than a non-bigmem kernel's. There's no way that non-bigmem kernels are smoother (like some people say) just because they waste a lot of RAM (the above commands output lines - empty ones are unused, every line is one MB), it's just a placebo. Nothing gets cached into it, it's not like userspace RAM.

Edit: 4 MB free RAM
[Samsung Galaxy Nexus] dbh369:
Yeah, but isn't the problem in the reboot meaning that useful kmsg would be from the kernel? Or maybe get really crazy and create unique names for both the ramdisk and the kernel? It would be just for test purposes.
[Samsung Galaxy Nexus] osm0sis:
Nah. That wouldn't have any effect. Not how it works unfortunately.
[Samsung Galaxy Nexus] shatteringlass:
I don't mean to repost, but any insight on this, [MENTION=4608636]bsmitty83[/MENTION] & [MENTION=4544860]osm0sis[/MENTION] :confused:
[Samsung Galaxy Nexus] osm0sis:
Definitely appears to be early enough in the boot to be legit. Nothing really jumps at me as causing the emergency remount, but maybe Smitty will see something as he knows more about that sort of thing. :)

How'd you manage to capture this by the way?
[Samsung Galaxy Nexus] shatteringlass:
Honestly? No idea. This reboot loop caught me in my sleep: I woke to the sound of the phone vibing at the bootloader screen, so I pulled the battery to have it boot correctly. Then I used SysLog to grab last_kmesg, which I read this morning.
[Samsung Galaxy Nexus] osm0sis:
Hmm really weird. The battery pull should have removed the last_kmsg for the looped boot from memory; there should have been none at all. :confused:
[Samsung Galaxy Nexus] kerpert:
Hi all, for restore the kernel stock, is enough erase the boot partition and then flash the boot.img inside the ROM?

I'm very undecided if try this kernel, hoping to benefit in a longer life of the battery, but I won't risk to loose any data.

i use the last version of Dirty-URSR :

in normal usage the phone is very smooth but games are very laggy(all my games)

i use [MENTION=2853378]Nephilim[/MENTION] settings
[Samsung Galaxy Nexus] cmoG530:
No dice. :( Reboots during "optimizing apps". Flashed the previous version and all is fine.
[Samsung Galaxy Nexus] osm0sis:
Weird.. News to me. Logs please!
[Samsung Galaxy Nexus] lollipop:
To manage Dirty-VSR kernel should i use trickstermod or synapse ? And what about Nephilim's settings
[Samsung Galaxy Nexus] Hetalk:
Either one is fine. Synapse's got a lot more options, as [MENTION=4544860]osm0sis[/MENTION] has set it up the way it should be. :good:
[MENTION=2853378]Nephilim[/MENTION] settings are based per trickster values. But, you can find and set similar values using synapse as well.

Choice is yours :good:
[Samsung Galaxy Nexus] rajputrajat:
just for information...

is it possible to change screen refresh rate as well as under-volt the screen.. by modifying the kernel source off-course?

or these are not exposed to kernel from firmware..?
[Samsung Galaxy Nexus] osm0sis:
Screen voltage is already exposed to userland. Most tweaking apps should support it, it's part of the massive list like VBUS, etc. El Google will tell you which one.

No idea about the refresh or if that's possible/advisable.
[Samsung Galaxy Nexus] lollipop:
Thanks,where can i find [MENTION=4544860]osm0sis[/MENTION] settings

[Samsung Galaxy Nexus] ILA:
Just do a backup and you won't risk anything. As for restoring the stock kernel, just flash the stock kernel.zip, no need to erase anything. As for boot.img, I think that that's the way to do it ;) OR you can just restore your backup which has the previous kernel in it ;)

Anyone finding it impossible to play webm videos with this kernel? And I'm not talking 1080p videos, even QCIF comes up with "cannot play this video". I know I used to be able to play the very same files on stock 4.3

[Samsung Galaxy Nexus] dezful:
Anyone know how to check suspend_trim using android terminal logcat?
[Samsung Galaxy Nexus] Marco618:
My gnex has been restarting itself lately :(
[Samsung Galaxy Nexus] osm0sis:
Like check if it's running? The counter should go up on the 4th line of /data/trimhelper when a fstrim gets triggered. I'll see if I can figure out how to pipe shell output to the logcat, or maybe the dmesg would be easier, and enable verbose on fstrim. :good:
[Samsung Galaxy Nexus] poo706:
[MENTION=4544860]osm0sis[/MENTION], I just saw this commit: https://github.com/LiquidSmooth-Dev...mmit/c4ed156b6f63a6f3075b724f4c1a208c8b20c354 . Does that mean that LS will be including dirtyv by default?

[poo]
[Samsung Galaxy Nexus] osm0sis:
Hah sick! Yeah, looks like rk's bringing stuff over from here and what I contributed to metalspring's omni-related device repo for building the ramdisk. :D
[Samsung Galaxy Nexus] dezful:
Yes. I'm wondering how to check it if suspend_trim is running. ;)
[Samsung Galaxy Nexus] osm0sis:
It runs if it's enabled. There should be a 1 (Boolean for enabled) on the 3rd line of /data/trimhelper; then you can see if it's triggered fstrim if the 4th line counter goes up. I'll add the dmesg output sometime next week probably, got a bunch of stuff on my to-do since I just got my PC set up again after moving apartments. ;)
[Samsung Galaxy Nexus] WarBorg:
overheating problem

hello, I flashed last night the SuperRam version of this kernel on a CM11 M7 witch previously had franco kernel and as soon as I booted I noticed intense overheating in the upper part of the phone and I think because of that my SIM card started to act crazy losing and regaining signal and it kept asking me for the PIN ... I restored the image I made before installing this kernel and everything seems to be ok now.

Am I the only one with this problem ? did some previous settings from perhaps franco kernel messed up with the dirty V settings, I must say that I did not change any voltages nor in the default kernel, when it had it, nor in franco.

I will try again with dirty V when CM11 M8 is available because I want to clean flash that update to be sure I don't run in any other problems and will let you know if the problem persist.

thank you
[Samsung Galaxy Nexus] ILA:
Yup, the heating is because the phone is actively searching for the network... And because it always prompted you to insert your PIN I think that there was something wrong with the SIM card (HW problem). Have you tried turning off the phone, taking out the SIM, reinserting the SIM and reboot?
[Samsung Galaxy Nexus] rkpeterson:
I havn't had a lot of time lately but yeah I am trying to put it all together so we have the best of the best...

I want to be able to build it all at once and not have to do any conversion or modifying of the boot.script.

Thanks osmOsis for the tips this morning, I had built last night and this morning I got an UCI error whenever I tried to start synapse. Hopefully I got it all now.

if i use Dirty-VSR,how much ram i will have?
[Samsung Galaxy Nexus] pedmond:
759 MB.
[Samsung Galaxy Nexus] lollipop:
First i have 758 mb ,i changed to franco kernel then go back i only find 757mb [MENTION=4544860]osm0sis[/MENTION] please can you tell me why this happen
[Samsung Galaxy Nexus] WarBorg:
yes, I did that and still, after the reboot, I had the same problem, as I mentioned, the moment I restored the backup everything seemed to be back to normal, it is very weird ...

PS I have a maguro device
[Samsung Galaxy Nexus] pattyboi:):
you changed kernels thats why..
[Samsung Galaxy Nexus] lollipop:

[Samsung Galaxy Nexus] michierusama:
Hi guys I miss this thread. I feel weird without phone LOL! well without smartphone...have a good day everyone! I see a lot of progress here.
[Samsung Galaxy Nexus] bsmitty83:
Probably some lingering CPU setting , try wiping cache and dalvik from recovery and see if it cures it . the most mentions of heating issues are caused and solved by this
[Samsung Galaxy Nexus] pattyboi:):
either:

use dirtyV SR

or:

build a custom franco with superram settings
[Samsung Galaxy Nexus] lollipop:
I use dirty-vSR but i found that 2mb gone maybe because of the rom i use carbon rom 01-07-2014
[Samsung Galaxy Nexus] pedmond:
It may be because of the ROM, but let's face it: we're talking about 0.26% of your RAM. Hardly worth mentioning, I would say.
[Samsung Galaxy Nexus] piterdemon:
Can someone share best setting for balance between performance and battery life? Nope I dont want nep setting because him settings make my phone laggy, sorry :p
[Samsung Galaxy Nexus] Wlld1:
Very strange. Can not apply any kernel settings on boot in Trickster or Synapse while screen is off. Phone goes to reboot. Need to keep screen awake while tweakers apply their settings on boot. Aokp or PA f2fs, clean install, all 3 kernels does not matter. Never saw this before.
[Samsung Galaxy Nexus] pianistaPL:
Honestly default DirtyV settings are good, you can just do CPU OC to 1400MHz/1500MHz. You can change governor to Dyninteractive.
[Samsung Galaxy Nexus] Nephilim:
My settings make your phone laggy? How so?

Sent from my Android 4.4.4 Galaxy Nexus
[Samsung Galaxy Nexus] KiD3991:
Its probably personal preference and usage. Like mine, you did mentioned clearly that 1600Mhz wont make much difference but consumes high power but my usage turns out to be the opposite. The difference is minimal but noticeable but the battery consumption is barely noticeable. So its all up to personal usage.
[Samsung Galaxy Nexus] Nephilim:
I get that, I built those settings to use as is or to modify, what I don't get is how they are laggy.

Sent from my Android 4.4.4 Galaxy Nexus
[Samsung Galaxy Nexus] KiD3991:
Well if the user's app does extreme ramping up to max freq every 0.5 seconds, it will surely hit Temp Throttle within a minute or two, and later on runs on low freq, therefore laggy. And if I did not remember wrongly you do set the temp throttle value lower is it? Especially interactive, which implements touchboost, but you already lowered the touchboost freq value, which puzzles me as well come to think of it. I'm still experimenting if Multi-Core power saving does an impact on the Performance VS Battery battle. Mind giving me some tips?
[Samsung Galaxy Nexus] matson36:
one biggest lag happen with my phone is the nomerge 0 setting. I think it costs IO takes longer
[Samsung Galaxy Nexus] Charmacas:
Hey!

I have a question to anyone on this thread. But please write me a private message because we need to keep this thread clean.

Does another ROM really make a difference?

I am actually on PA 4.41 F2FS with micro gapps and the newest DirtyV. I am satisfied but I think it may could be better. Does anyone have real experience?

[Samsung Galaxy Nexus] osm0sis:
I've found MCPS breaks the min freq when enabled at all. Fransisco said at one point that it doesn't work on OMAP so we're probably better off leaving it alone.

[Samsung Galaxy Nexus] namtombout:
Different toolchains, optimizations, cherry picked vs. non cherry picked, bugs etc makes a difference. I really notice the difference in roms when i restore my call log and sms using mybackpro. Some roms are blazing fast in restoring and others arent. I've been using Team EOS nigthlies and this dirty ass kernel and couldnt be happier.

Paradox of choice, you'll never be satisfied with any rom buddy
[Samsung Galaxy Nexus] Nephilim:
Guys, don't be scared to give me recommendations over on my thread and why you think they might work better. I created the thread with the intention of creating optimal settings for our device and I'm not always right. I take all your suggestions and opinions into consideration. There have been many good recommendations given to me that I have added to my settings over the time the thread has existed.

Basically, by all means school me if you can. We all benefit from the best settings. :)

If you really want to f*ck up your overall IO set it to anything other than 0. We experimented with it extensively in the Franco's Dev Team tuning collective, and 2 is fastest feeling with deadline (with front_merges 0 and fifo_batch 0; turns it into a smarter noop), but I/O gets choked and the Play Store freeze/bottleneck gets worse by like 100x. 1 is better but not by enough, so 0 is the only all-around usable option.
[Samsung Galaxy Nexus] piterdemon:
Thanks man, I change my settings to 0 in deadline and finally I got back 20mb+ write speed instead of 4-6mb [emoji481]

[Samsung Galaxy Nexus] matson36:
Thanks for your information and with all the respect I didn't mean to doubt the dev but it just happened to be less laggy when no_merge was 0 with sioplus, zen. Perhaps my phone is kinda broken and weird settings works... :\

I think I will stick to deadline for now. I notice that addrandom was 0 in 6.15 in dirtyv, changing it into 1 works way better.

Thanks for your help! :)

PS: i notice about no_merge 0 is that when I take a lot of screenshot continuously, after 50 or more, the images become empty.
[Samsung Galaxy Nexus] osm0sis:
0 is the best for I/O speed, yes, but we did manage a faster feel with settings that (counterintuitively) cripple I/O by playing with nomerge and deadline. ;)

Add random is useless because we have flash storage. It's meant for rotational (spinning disk hard drive) devices where the jumping R/W heads are a good source of entropy. Start running Synapse, I've explained the block queue scheduler tweaks in it better than I've seen in any other app. That way you'll know what you're adjusting. :)

P.S. Fu*k! Google Play services is holding 100% NLP wakelocks on me again. How could they finally fix that in 4.3 and then regress it for 4.5+ and not notice. 0% deep sleep makes me angry. :mad:
