Unable to download r126 - keeps timing out. Anyone else having the same problem?

I click on the r126 link on this page (https://cld.pt/dl/download/9bd42194-b8f4-41b0-88a3-05be71b58fc1/Code_Blue_downloads.html) and it just sits there thinking about it.

Really happy with this kernel, running it with purity rom,

Took phone off charge before went to bed, only lost 2%,

Went out but forgot my phone so overall I'm very happy!
[Nexus 5 Original Android Development] eng.stk:
You messed with the sleeping dragon... no so funny now hum? ;p

Download is fine...
[Nexus 5 Original Android Development] Nucleotide:
Haha! :p

Tried again using IE and it's downloading fine now. Chrome continues to time out.

Thanks a gain for your great work. Greatly appreciated as always. :good: :good:

I can also confirm Code Blue + Carbon = Battery Friendly with excellent idle drain.

Screenshots from mostly reading and texting usage, under wifi and 2g, no games, location off, default kernel settings except sound.

1 Carbon update flashing incuded + a couble of reboots in the above usage. :D

Fortunately battery statistics continued normally.

Only concern a little "high" temps ( average about 42-45C ) but the last days the weather is hot in Greece so i dont know if it is environment related "issue" :silly:

I wanted to try your kernel (r126), but it causes my phone to bootloop. I'm on Miui Rom.

I have no problem installing ElementalX or Bricked kernel
[Nexus 5 Original Android Development] ironjon:
Try installing stock kernel first

Sent from my Purified Nexus 5
[Nexus 5 Original Android Development] Surfinette:
That's what I did. I installed code blue kernel over the Miui Rom, which uses stock kernel
[Nexus 5 Original Android Development] unsivil_audio:
Anybody, use Tasker CPU profiles with this? Is the hotplugging the reason we can't control core 2 and 3?

Regardless coming from ElementalX, Carbon Rom + CB Kernel = Amazing battery life. Don't get me wrong ElementalX was great, but his governor was not written with my setup in mind (too many apps running).
[Nexus 5 Original Android Development] senotrius:
Exactly. Not the heat.'something' else.that's what got me confused.I'm trying to find out. Has xposed been known to mess up?I use it primarily for minmin and adblockers.No performance mods.I tried disabling it but no luck. Maybe some of the governor parameters?

Rite now it shows 2265 as max.no prob.but it will soon go back to lower setting. Maybe in a day.
[Nexus 5 Original Android Development] eng.stk:
Read OP: I don't support setups with xposed installed.

You can have something pegging a cpu (happens with some root apps), making load spikes and throttle spikes generated by it.

Throttle is not immediate going up or down, takes some seconds.

It's enough time lapse to go up and down making that behavior on your freqs.

Those exact 2steps are used by temp throttle, can't be a coincidence.

Find the culprit elsewhere, not a kernel issue.

i must flash kernel first than supersu 2.61 or the other way around ?
[Nexus 5 Original Android Development] tmihai20:
No, you must first flash SuperSU 2.61 or newer, then you flash the kernel.

latest purenexus (clean flash) and blu_spark kernel (stock settings), i have two reboots again.. no mods

ps. [MENTION=3873953]eng.stk[/MENTION] i love your kernel but i have the same problems (random reboots) every time, on every rom i have tried.. i don't know how do...
[Nexus 5 Original Android Development] eng.stk:
As in OP, I don't do debug on custom ROMs:

Neverthless, you had no kernel errors but watchdog bites, probably due to timeouts/sync errors on radio support subsystems, which is totally stock in blu_spark.

[MENTION=3873953]eng.stk[/MENTION]

Really loved this. Just switched back to blu_spark after 3 versions of fk.

Aince the update. I noticed a lot improvements and im hoping ill get the same wlan_wakelock as of fk, since most wifi tend to sleep when screen is off which i do not really like to see when im downloading.

Ive also configured it to 1 core when screen is off and 1 core minimum online. Increasing hspeed load to 98 and boost value to 600 mhz to avoid unnecessary power consumption. I am yet to test the performance on games and ita battery drain on high-end graphics.

I will report back once im done testing.

Whats bugging me is your take on minimum cpu always online. Is it more battery friendly if you have 2 cpus always on sharing the load or just 1 cpu and hotplugging the second to turn on once it reaches 90% load? Thanks in advance
[Nexus 5 Original Android Development] bigknowz:
New Device

Please say N6P :victory:
[Nexus 5 Original Android Development] eng.stk:
2 min cores will give you the best battery/perf ratio. Using 1 core will online/offline cores too often making more overhead and thus using more power.

On screenoff 1 core is not enough for some operations and you will not save any battery from having 2 cores.

Nope, no 5x or 6p and probably not the next Nexus either if Google continues the current policy on Nexus line.
[Nexus 5 Original Android Development] phantom146:
Ive already tested two cores and i agree that its suitable on the performance side but upon checking cpu freq table with 2 cores it tends to ramp up a lot down from 600mhz which i set my touch boost going up to 1900mhz and i dont know why. With a cpu load of 4% ive seen the two cores go high and lows with apparently almost no basis while 1 core has lower ramp up speed.

If im correct i guess i have to disable the multicore powersaving right? Any advice on this?

After checking it out just about now, turning off multicore powersaving isnt doing anything good about the ramp-ump :/
[Nexus 5 Original Android Development] eng.stk:
No, you are seeing what a tool shows you.

In 1 sec or half sec there were already 1000 load calcs you don't even see.

All the values have been tuned for years, most stuff you will try to keep battery usage down will make it go up.

Advice: use default values.
[Nexus 5 Original Android Development] phantom146:
Alright will follow your advice and restore it to defaults will report back after a day of usage :) thx for the quick reply!

Is there any know issues with latest SuperSU versions?

I remember last month i had to flash, wipe, reflash, rewipe [...] repeat for an entire night to get the right combination!
[Nexus 5 Original Android Development] alen1901:
Just use 2.62-3. When updating kernel, first flash superSU, then kernel. And it will work without any problems. Bare in mind that you must not have any other superSU installed, if you have you need to flash unSU zip first. Also, android pay will probably not work with superSU 2.62-3.

From my testing, on ARM power aware workqueues just brings down the performance with no visible battery gains.

Same goes for CFS policy (worst even because that would need a full port to 3.4).

Sorry, I saw kernel panic and I thought it was related with the kernel.

NM.

BR.
[Nexus 5 Original Android Development] eng.stk:
Kernel panics can be triggered for several reasons.

Watchdog is a protection when something is asked and the system can't deal with with. After a timeout it reboots.

Wdog bites normally are caused by memory management issues (like apps or framework derping), address sync errors, dereferencing issues, memory leaks, etc.

To know if your running in f2fs if you have terminal emulator

You should be seeing a f2fs somewhere there

Or reboot to twrp

Wipe, advanced wipe, tick data, then repair/change filesystem and you should be able to see there on top if your running ext4 or f2fs

Hi [MENTION=3873953]eng.stk[/MENTION]: out of curiosity, are we "impacted" by this vulnerability? I've read the patch was already available here.

[Nexus 5 Original Android Development] gufoman88:
Maybe not. In the article it say that the vulnerability is only for kernel based on 3.8 and higher. This kernel is based on 3.4. Maybe with some backport we are impacted too. Only eng.stk can give us answer.

Inviato dal mio Nexus 5 utilizzando Tapatalk
[Nexus 5 Original Android Development] eng.stk:
You're welcome ;p

You're probably running ext4 if you don't know.

You can change from ext4 to f2fs, there's an how to in OP.

Like others already said, beware that all your data will be deleted, don't forget to backup if you do it.

But you can continue using ext4 if you're happy with it, don't need to change nothing, just flash kernel.

Our kernel is 3.4 and probably is too old to be impacted by it.

I just checked the patch with the fix and seems like new 5x and 6p are affected by it (kernel 3.10).
[Nexus 5 Original Android Development] drac0:
Indeed, I've been using f2fs from its beginnings all the way to early Code_Blue builds and system-wide boost in performance is just phenomenal! Anyone who says that its similar to ext4 havent even tried f2fs long enough to witness its speed and snappy response. Kudos to our dev for implementing latest f2fs commits! Cheers! :highfive:

And which partitions you have formated to f2fs? Only data and cache? Do you see any difference in transfering data from pc to phone, phone to pc, or in phone from one folder to the other?

[Nexus 5 Original Android Development] eng.stk:
Nope, already talked about it.
[Nexus 5 Original Android Development] drac0:
Only /data and /cache partitions cos you wont get any from /system since f2fs is famous for its i/o and r/w goodies. PC to phone and vice versa is something that depends on much more than file system but from one folder to another of course. Also snappiness its just stupidly fast, launching apps and everything else that is r/w related, there is visible difference. Best seen if you try it for yourself, you wont regret it. And yes everything is working just fine with f2fs, its just file system and quite snappier one! :good:

---------- Post added at 02:21 PM ---------- Previous post was at 01:52 PM ----------

I dont wish to stuff the thread with f2fs anymore, but there is an old trick to convert your /data and /cache partitions from ext4 to f2fs without losing any of your precious internal data. Basically you just,

1. nandroid your /cache and /data partitions,

2. copy your backup to your PC just to be sure,

3. rename your backup files in order to replace ext4 in backup names with f2fs.

4. format your /cache and /data partitions to f2fs

5. restore your renamed backup files,

6. flash latest spark, cos its the kernel that runs f2fs,

7. reboot and profit.

You wont lose anything since you've just restored your f2fs-renamed backup made from ext4 internal data. However I would recommend clean flash after setting up f2fs. Cheers!

Hello [MENTION=3873953]eng.stk[/MENTION], would you consider enabling the back-light dimmer by default? I know i can do so using an app, but it would save the hassle.

Beware that restoring backups from different filesystems can derp stuff, I had issues with this in the past.

Only supported way and which I advise is to use TiBu to backup data and copy stuff to PC/USB, for a clean flash.

You can create profiles with Adiutor and get tasker to set them automatically probably.

Ask around Adiutor usual places.

f2fs makes overall system snappier, scrolling is smoother,long file tranfer is a lit bit faster, less overhead on CPU with I/O operations, better eMMC health and performance on long term.

But it won't be 200% better ofc.
