zram or compcache on mako

What happened to zram or compcache on mako ?

I'm not sure if it's missing on other devices, or if it's missing upstream in CM10.1, but it should be there, no?

Also, it's quite possible that I forgotten how to use it :(

Anyhow, if it's really missing, could you please add it to the next build?

Device: mako

SentinelROM Version: 4.60

Reproduce:

Go to Settings -> Performance -> Memory management -> zRam

Activate it.

This is developed and maintained by the CM team. its a little buggy which is why I included LMT instead.
[Nexus 4 Android Development] pawan1993:
I would think zRAM is activated when the dedicated RAM is close to full so that your internal storage doesn't die from the crazy R/W's that RAM requires. Either way I don't think you'd really need to enable zRAM. The N4 has enough RAM for almost anything it can do.
[Nexus 4 Android Development] horza:
It would be nice if zram and compcache worked that way, but unfortunately, they do not. They don't use storage, and they are activated as kernel modules, and mounted as swap.

I want any of them because I prefer the kernel to push purgeable assets to swap (lzo-compressed ram, not storage), rather than having them actually completely purged from RAM and then read from storage when accessed.
[Nexus 4 Android Development] pawan1993:
Oh I see. So basically it's a user defined portion of RAM that is compressed? If it loads up as kernel modules, have you tried using a different kernel?
[Nexus 4 Android Development] horza:
yes, on all that i compiled, and on all CMs that ever came with it. also on dozens of servers and desktops. And 26% setting that CMs GUI has is just perfect for most devices.
[Nexus 4 Android Development] jedinegotiator:
Sentinel, whatever you have done to make the battery life on this awesome you have done an amazing job. I can literally use my phone all day and be at 60% when I go to bed.

Thanks for the awesome ROM!

Do you plan on making ROMs for the GS4 Google Edition?
[Nexus 4 Android Development] Sentinel196:
Thanks, and yes . Plan to support it.
[Nexus 4 Android Development] nileshgr:
Turns out, cm pie controls aren't buggy at all. It seems sweep2wake and pie controls interfere with each other. Disabled sweep2wake and everything's fine now. #tip

Sentinel196 - build schedule?

Hi Sentinel196 - just a quick question about your build schedule...

Is the order you release your ROM in down to how you build them (ease etc)?

Or is it down to demand (i.e. the most popular devices get built first)?

Just curious.

Still loving the ROM though - running 4.60 with Franco kernel nightly #153 at the moment - amazing battery life - especially in standby (overnight, with no use, but data enabled, I'm getting about 0.5% battery drain per hour!)

Looking forward to 4.70...
[Nexus 4 Android Development] facile12345:
Is it possible to have a screen on battery screenshot ?

the amazing battery life comes with the built in kernel ? It won't be the same with franco ?

Finally why not putting PA pie with shortcut right for notifications and shortcut left for quick settings ?

Thanks for answering
[Nexus 4 Android Development] Sentinel196:
I don't have a nexus 4 so can't provide a screenshot, however most people are getting around 4-5 hours of screen time with this ROM.

I'm not putting in PA features because it's not a PA ROM. If you want those features, flash PA.
[Nexus 4 Android Development] facile12345:
Okay thanks for answering, I meant juste Pa pie, it's better than the lmt one, but whatever.

4.60 Still running strong, also getting really good battery life with air kernel:thumbup:
[Nexus 4 Android Development] Sentinel196:
Glad to hear it. the v4.70 update isn't too far off now. I've just been sorting out some issues with Samsung devices, which has delayed the update a little.
[Nexus 4 Android Development] Sentinel196:
SentinelROM v4.75 is here!

17/06/2013:-

v4.60 -

*Compiled with new Linaro 4.8 toolchain for a additional performance boost.

*Updated to latest Mali graphics drivers for improved performance and stability.

*Updated to latest CM10.1 source (Android 4.2.2)

[NOTE: You must wipe your System and Dalvik caches after upgrading. GAPPS Must be re-installed after updating. Please view the instructions here.
[Nexus 4 Android Development] facile12345:
Is it possible to have all those tweaks, but based on the stock rom which is very fast, stable and stuff ?

I mean a stock custom rom with stock custom kernel :c
[Nexus 4 Android Development] lowrider262:
I used to think the same thing, I always wanted ROMs that were stock based cause I thought they would be more stable. But then after thinking about it I realized that a good portion of the tweaks/mods on the stock based roms are based on cm anyway, and the way I look at it they were built to run on cm ROMs. So in a way its probably a better choice to just run cm or a cm based rom (like this one) for maximum compatibility, resulting in stability. This all just my opinion btw, it may be true or not.

/end rant:p

Could anyone make mirror? D-h drives me nuts. Still cancelling download :banghead:
[Nexus 4 Android Development] KerryWood34:
Thanks that did it. Haven't used CM in a loooooooong time so did not know they had put that in Developer Settings

---------- Post added at 03:41 PM ---------- Previous post was at 03:30 PM ----------

I am uploading to my dropbox right now. I will post a link when it is done.
[Nexus 4 Android Development] mikaole:
never post a dl link for a Rom unless you own it. The devs like to see how many dls are done.
[Nexus 4 Android Development] Ibkevin:
I don't have a credit card or PayPal or I would def donate at least a little something to you. Since I can't do that I will tell you thank you very much! Not only is this ROM really stable but its also extremely smooth on my phone. I say that having tried quite a few of the ROMs available for the nexus 4 too. One of the problems I've had with my nexus 4 is that there are several really great devs building really great ROMs and its hard to decide one to stay on for me lol. That's really more of a good thing than a problem but anyway I'm really enjoy your ROM extensively. It definitely stands out and I thank you. All of us who are not developers and come onto the xda forums are already really lucky to have all you great developers making fantastic ROMs that you're willing to share with us. I humbly thank you for giving us yet another really amazing ROM. It may not be the same as cash Lol, but I give you mad respect and props.:thumbup:
[Nexus 4 Android Development] Sentinel196:
I'd prefer no mirroring please. I'm trying to track my downloads.
[Nexus 4 Android Development] Sentinel196:
I've PM'd you a private download link.
[Nexus 4 Android Development] jarjar124:
The music app is amazing! Only complaint is the playing icon in status bar. Other than that, great ROM!
[Nexus 4 Android Development] Sentinel196:
Thanks!

You can switch off the notification. In the music player, go to settings-Notifications- and switch off "show when playing"

The music player also has widgets if you need quick access to your playback controls, but don't want them in the status menu.
[Nexus 4 Android Development] Jedipottsy:
Downloading now very slowly. D-host and goo.im are very slow for me, assume because I'm in the UK. Sounds like a great rom, haven't used cm much, leaned towards AOKP/xylon with Trinity.
[Nexus 4 Android Development] Sentinel196:
That's strange. Dev-host is lightning fast here in AUS.

Looking forward to your feedback, if you're used to AOKP I think ou'll love this ROM. It's much cleaner than most AOKP ROMs I've tried.
[Nexus 4 Android Development] Zainiak:
here in the us, its super slow (for me at least) and i have a 60mbps down and 15mbps up here

btw, nice sig sentinel :D
[Nexus 4 Android Development] jarjar124:
It finished in 2 minutes me here in us. 25mbs :p
[Nexus 4 Android Development] Sentinel196:
Sorry guys. i didn't realise it was so slow elsewhere.

I have another host which I sometimes use, but they don't allow me to track downloads and have a habit of just deleting my files without any notification, so I prefer to use Dev-host.

Until the ROM is earning me enough in donations to pay for my own file hosting, I can't afford to host the files myself as the bandwidth required is pretty high.

I have a 5GB a month bandwidth limit with my current hosting package, which is nowhere near enough.
[Nexus 4 Android Development] 19deimon90:
Hello, thanks for the rom, is very smooth!

Just a few questions:

1)There is a way to have the compatibility between your kernel stock and the app Touch Control?

2) And a way to change the gamma color like the paranoid color?

3) how works the ota update? I don't see any option to check update.

Thanks.
[Nexus 4 Android Development] Sentinel196:
Hi. I'm glad you like the ROM.

I don't have a Nexus 4 myself, so it's difficult for me to test this. Touch Control requires Sweep2Wake kernel support. You might be better off flashing a different kernel if you find it's not working with mine. My ROM should work with any CM10.1 friendly kernel.

Not without manually hacking the ROM (which you're welcome to do).

The OTA Update software automatically scans my server when you power on the phone to see if an update is available. You can also choose under settings to have it check at different intervals.

If an update is available, you will be prompted to download it and install it. The phone will check the checksum, then reboot and automatically install the updated ROM.
[Nexus 4 Android Development] adityak28:
Hi Sentinel196. Does this release include the fix for the SystemUI memory leak? I think the 13/4 CM build included that fix. Thnx :)
[Nexus 4 Android Development] Sentinel196:
Hi mate. I sync'd the source on the 14th so it should be included. I haven't come across any memory leaks on my other devices on this build.
[Nexus 4 Android Development] adityak28:
Ok. Just installed the ROM and the initial impressions are all good. Will use it for a day and report back :)

Edit: Is the max freq is set to 1188 MHz by default? (I'm unable to upload a screenie from the xda app for some reason..)

[Nexus 4 Android Development] facile12345:
I really think that google has some tweaks that you can't find on AOSP, so tweak it more could be better. there's only AOSP based rom on n4 and they seems for me, less good than the stock one, that already have Very good battery life, perfect stability, perfect smoothness and Really,really bugfree.

I have lot of issues on other roms, I don't know why, So a stock based rom could be welcome for me, even if it have less customisation.
[Nexus 4 Android Development] Droid2drummer:
Yes. CyanogenMod team was and still is "Top Notch" its truly where miracles happen in our devices. In fact Google I'm positive enjoys the work they provide. The head guy of Cm in 2010 was given a big job offer at Samsung and he took it. These guys aren't cooks or "Kangers" they are coders. They are the elite in my opinion and in ma y others. This is not to say kangs and cooks Dont bring good work to the table but cm is the work ...and the miracles of android...
[Nexus 4 Android Development] facile12345:
Surely, but stock is far superior to any. I'd be happy to see all sentinel tweaks on stock.

Sentinel could you create a second version of this rom, stock based and tweaked also ? please please :)
[Nexus 4 Android Development] Palingenesis:
Mirror for latest build? Said too many people downloaded from the original link.
[Nexus 4 Android Development] JmPTaz09:
Me too... :(
[Nexus 4 Android Development] Sentinel196:
I'll upload one ASAP
[Nexus 4 Android Development] Sentinel196:
MIRROR now available on my download page.
[Nexus 4 Android Development] facile12345:
Please answer sentinel, your rom could be a beast if you do the same with stock. :confused:
[Nexus 4 Android Development] Sentinel196:
My ROM is based on cyanogenMod source. I have no plans at this stage to base it on AOSP source.

The first iteration of SentinelROM for nexus 10 was based on AOSP rather than CM and people complained there weren't enough features.

Whatever I do, people will always complain they want something different. the current system seems to please the most people.
[Nexus 4 Android Development] facile12345:
Stock rom is not AOSP.

By the way, I don't complain, I just suggest, sorry if you felt it that way.
[Nexus 4 Android Development] Sentinel196:
I wasn't suggesting you're complaining. Just saying that its hard to please everyone :)

I realise stock ROM isn't pure AOSP, but the source for the stock ROM isn't available, so I can't compile it myself like I can with pure AOSP or CM.

If I were to build from stock ROM it would have to be a cooked ROM, rather than compiled, and a lot of the benefit would be lost.
[Nexus 4 Android Development] facile12345:
Oh okay, it isn't possible to compile from the zip of the rom ? I mean isn't there stock based touchwizz rom and sense in other devices, Those are closed source too ?

Well thanks for answering :)
[Nexus 4 Android Development] Sentinel196:
That's just compiling a zip, but from already compiled apps and source.

With SentinelROM, I compile from pure source code. Big difference :)
[Nexus 4 Android Development] facile12345:
Oh okay ! Thanks.
[Nexus 4 Android Development] JmPTaz09:
Don't worry about the complainers, CM is beast for sure. If you want stock, run stock. If you want a nicely tweaked CM based rom, run Sentinel Rom. :beer:

What build of CM10.1 is SentinelRom 4.75 compiled from?

Thanks....
[Nexus 4 Android Development] Sentinel196:
. It's compiled from source. Not from a build.
[Nexus 4 Android Development] Kc_Nirvana:
Thanks for the answer...

I am very noob so if i say some idiot thing just tell... :D

You compile from source its like the day that you compiled your build have the tweaks solved from Cm of that day right?
[Nexus 4 Android Development] android88:
Yes, but not just "tweaks" - it's also other merges that have been merged in that build for that day...
[Nexus 4 Android Development] Kc_Nirvana:
So...

The right quesetion is what day have you compiled from Cm sentinel196?

Thks...
[Nexus 4 Android Development] Sentinel196:
Have a look under settings- about and look at the date the kernel was compiled. That's when I synced. Its uaually 1 or 2 days before I release the ROM depending on beta testing.
[Nexus 4 Android Development] ozzie1p:
Damn nice job with this rom! I'm surprised it isn't getting more attention, its had the best battery life of any rom I've ran. Thanks for your work.

[Nexus 4 Android Development] smoka206:
If you want a stock ROM why not go with RasBean or maybe go back to stock! I love this ROM it has a very good amount of tweaks and its snappy as hell. Much better than stock for me. And I can barley tell the difference in speed between diffenent ROMs. The N4 is a beast, my GF is on stock non rooted and her phone seems as snappy as mine. Anyways keep up the good work, I love your ROM.
[Nexus 4 Android Development] Sentinel196:
Thank you so much to everyone who has donated to help my friend with Brain Cancer. We have raised a significant amount so far! 9 days of donations to go, so it's not too late to help out if you're keen.

Hey Sentinel. This ROM has been amazing with the battery life and speed.

I was wondering if you plan implementing arrows keys in the navigation bar whenever the keyboard is available. I found having them in PAC was quite a treat when editing whatever I typed, so I would really love to see that kind of feature.

Thank you!

Hello...

I am not asking for an ETA or kind....

Just one question:

The new versions of Sentinel Rom will be build from Cm10.1 stable or stick it in the CM10.1 Nightlies?

Thanks in advance
[Nexus 4 Android Development] Sentinel196:
Please read the OP. SentinelROM is not based on nightlies. it's synced and compiled from CM source. Completely different from a cooked ROM.
[Nexus 4 Android Development] bodom_hc:
tried this rom on my nexus 10 a while ago

wasnt feeling touch screen controls for games, now that i got my MOGA controller thought i try thi out :)

and man i can definitely tell the games run better (while using the same kernel settings) and now im using faux kernel and even better!

keep it up

also normally I ALWAYS USE NOVA launcher, but yours..... so... so kool. im not even using nova atm, if you can install icon packs i would go craxzy lol

any possibilities of allowing icon packs!?
[Nexus 4 Android Development] bodom_hc:
anybody know if its possible to disable the option to REBOOT, POWER OFF, ETC while screen is locked? (reason being incase my phone was stolen) i wan it kept on so i can track it
[Nexus 4 Android Development] Sentinel196:
The phone will always be able to be rebootedand forced into bootloader to be reflashed via hardware keys.
[Nexus 4 Android Development] nileshgr:
For that reason, it's best to use something like Avast which obfuscates itself as another service in running apps section and I believe gets preserved even on factory resets [req root/CM, not sure].
[Nexus 4 Android Development] Sentinel196:
I dont think any software will stop the battery going flat, or someone holding down the power button for 10 seconds.
[Nexus 4 Android Development] nileshgr:
But it locks phone if you send command from web interface (or another number registered as friend). The ultimate way out would be to get into recovery and flash ROM. You can track your phone, it'll survive even factory resets (if you enable Device Admin).
[Nexus 4 Android Development] nileshgr:
Sentinel,

Some security updates have arrived in CM. Waiting for update :)

Also include privacy guard if available? I read that somewhere, but don't know if it is there for public use yet.
[Nexus 4 Android Development] Sentinel196:
I'm on vacation until August 19th. Updates will come after I get back :)
[Nexus 4 Android Development] hookguy:
Hope this continues to get developed, best rom on Nexus 4 by miles, and I've tried a lot of them.

Keep up the good work!
[Nexus 4 Android Development] nileshgr:
I can definitely agree with that. I couldn't find a single good 4.2.2 ROM after this started lagging behind.

Waiting for a smooth 4.3 release from Sentinel.
[Nexus 4 Android Development] Yusei:
He's back.

Don't worry guys.
[Nexus 4 Android Development] chainer22:
Huge fan of this ROM! even with wakelocks caused by the google systemupdateservice bug, i am still getting awesome battery life!

any chance sentinel will release a fix for the 4.3 system update bug that is draining data/battery? :D or will it be straight to 4.3?
[Nexus 4 Android Development] Sentinel196:
