You could use the command 'pkill zygote' in a root terminal in sfdroid, this will restart sfdroid and your connection should be fully working.

Have you tried accesing the /storage folder as root?

You can access the Android storage within SailfishOS and even sftp in '/data/media/0/'. No need for 'root' privileges. Over sftp I can just drag&drop files within the filemanager (Gnome/Linux).

I've had the same problem, then i switched to 2.0.1.1 and now works fine. Maybe you have first to install the old version and then do an OTA upgrade.

Not that I would have a solution to your problem, but you indeed do have a 'java.lang.NullPointerException:' when starting 'sfdroid.sh'. My start sequence on 'SailfishOS 2.0.4.14' would look like this...

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview

Small kernel update...

Kernel v8

Changelog:

Code:

- Reverted fast charge back to first version due to slow charging



- Added msm_mpdecision aka "bricked hotplug" cpu hotplug governor

MSM_mpdecision is a highly customizable hotplug governor:

Code:

Check /sys/kernel/msm_mpdecision/conf/ for the configuration.



startdelay = time until mpdecision starts doing it's magic (20000)

delay = time between checks (70)

pause = if something else plugs in the cpu, fall asleep for 10000ms (10 secs)

scroff_single_core = if the screen is off, don't plug in cpu1/2/3. Additionally: Unplug all cpus except cpu0 when screen is turned off (1)

enabled = enable(1) or disable(0) mpdecision. This does not affect scroff_single_core!

min_cpus = min cpus to be online, cannot be < 1. Default: 1

max_cpus = max cpus to be online, cannot be > 4. (if you set it to 2 and min_cpus to 1 you will basically have a dualcore) Default: 4

idle_freq = a value against that will be checked if a core +/- is requested. (486000)

If cpu0 is below that value and a core up of another cpu is requested, nothing will happen.

If any other cpu is above that value and a core down of that cpu is requested, nothing will happen. (otherwise it would now put down that cpu even though it is still working, which isn't what we want)



Hot plug thresholds (aka now it gets 'complicated')

This small formula calculates which value will be used: (number_of_cpus_online - 1) * 2

The result of this formula will be the nwns_threshold where a new cpu is hotplugged.

The result of this formula + 1 will be the nwns_threshold where a cpu is unplugged.



nwns_threshold_x = runqueue threshold, if this is reached cpuX will be hot/unplugged

twts_threshold_x = time threshold, this amount of time must have passed for the related action to be taken (hot/unplug)



Example:

One cpu is online.

(1 - 1) * 2 = 0 ergo:

nwns_threshold_0 = cpu1 will be hotplugged at this value

((1 - 1) * 2) + 1 = 1

nwns_threshold_1 = cpu0 will be unplugged at this value

Since we can't unplug cpu0 this is '0'.



Two cpus are online.

(2 - 1) * 2 = 2 ergo:

nwns_threshold_2 = cpu2 will be hotplugged at this value

((2 - 1) * 2) + 1 = 3

nwns_threshold_3 = cpu1 will be unplugged at this value



etc...



The default values are:

NwNs_Threshold: 12, 0, 25, 20, 32, 28, 0, 35

TwTs_Threshold: 140, 0, 140, 190, 140, 190, 0, 190

Where the position and function of the number equals the result of the above explained formula.



(all times are in ms)

So, for example by setting "nwns_threshold_4" to a high value (e.g. 90) only the first 2 cores of the cpu will be used at averge load/usage. Core 3 and 4 will only come up under very high load.

Don't forget to disable stock mpdecision hotplug governor, when using an alternate hotplug governor!

Kernel can be downloaded here.

Do you use okboard or only the stock keyboard?

You can access the files and folders of sfdroid normally like it used to be on an android only device.

sdcard for example can be found at /storage/sdcard0. Maybe you need root priviliges to access the folders.

I use the stock keyboard, but I think your question might've been directed at the other guy. :) I helped him out with his EAP thing after quoting his post.

There is a bug in okboard, that causes the transparency issue. Only solutions are use another browser like Webcat or Webpirate or don't use okboard.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview

During my testing of the new features in the 'mautz' kernels, I started to write a script that generates some basic battery 'poll data'. The last couple of days, the script has evolved and grown, and I guess it's time to share it with you.

The script does basically log the current power consumption with a given interval and (now) generates a report at the end. The report includes some useful information about the current phone settings, allowing you to compare different testing situations easily.

The first version is ready now and is compatible with the 'mautz' kernel_v8, but should also run with the default kernel, besides the fact that some files, the script is checking, are not present. You will have two files, the 'script-routine' and a 'starter', that allows you to launch the routine with individual options. The source code can be found here... https://github.com/minimec/powerstats/tree/master

The report file would look like this... report file
A 'gnuplot' of the file would look like this... gnuplot file

I recommend to download and decompress the '.tar' file with the following commands on the phone, but you can also download the file here...

Code:

curl -L -o powerstats_v1.tar.gz https://www.dropbox.com/s/2wt7hd69la4j116/powerstats_v1.tar.gz?dl=0

tar -pxvzf powerstats_v1.tar.gz

You will get a 'powerstats' file and a hidden '.powerstats-routine' in your '/home/nemo' folder. A 'powerstats-report' folder will be created during first run.

You can get an overview of the options with './powerstats -h'. If you launch the starter with './powerstats', the routine will run with default settings. The 'starter' approach allows you to close the terminal right after launch...

A good first test might be...

Code:

./powerstats -i 2 -m 1 -n 1 -p 40 -t first-try

Code:

[nemo@pris ~]$ ./powerstats --help            

Script to measure current power consumption

on devices running SailfishOS.

 

EXAMPLE:

./powerstats -i 1 -m 30 -n 1 -p 50 -t gps-moving 

 

options:

-h, --help                        show brief help

-s, --stop                        abort script

-i, --interval=INTERVAL        specify interval (default = 2)

-m, --minutes=MINUTES                specify measure time in minutes (default=60)

-n, --notification=NOTIFICATION        set '1' for notification (default=0)

-p, --processlog=PROCESSLOG        specify limit in mV for process logging (default=60)

-t, --title=TITLE                specify a title for output file (default=idle)

[nemo@pris ~]$

I would love and I hope to see some shared reports, that would allow us to compare the Neus5-SailfishOS experience with different OS versions and settings.

I stay tuned for questions and new ideas from your side.

Thank you!! I'll try your script in the next days, at the moment i'm fighting with a new kernel :-D

EDIT:

Just downloaded your tool and tested it with your 'first run' suggestion. Very nice!!!

This gives a much more detailed output than SystemDataScope in terms of Power consumption.

Thank you, awesome!

Yeah.. I did see your first positive notes on 2.0.5.6 and do not read any rants by other users like 'mautz' or 'BluesLee'. So I might upgrade at least my testing image quiet soon.

That looks like a pretty nifty tool. On my side I cannot tell you whether my 'process triggering' is really accurate, and yet it seems to do the trick.

I did a new 'powerstats' analysis. I wanted to know the impact of the 'sailorgram -deamon' on battery life. I did 3x times the same walk, once with 4G/'sailorgram on', then 3G/'sailorgram on', then 4G/'sailorgram off'. In between I made a ~7-10min. pause at home. The result was stunning... I don't not run the 'sailorgram -daemon' permanently anymore, but only connect from time to time... (The high peaks is where I turn the phone on to switch from 4G to 3G and back). ;) See the results

This is my SystemDataScope output, seems that your script is a little bit CPU hungry ;)
http://up.picr.de/27595821pc.jpg

Is it possible to let the sort command run less often?

Concerning your Sailorgram observations...in my opinion SFOS isn't a very battery friendly OS. Everything causes battery drain, nearly every application causes too much CPU load when the phone is put to sleep, even the message app...

If you have a good 4G reception in your area you could leave 4G always on, i didn't notice a difference between leaving the phone in 4G mode or using 3G and only turn 4G on for mobile data usage.

At the moment i have to charge the Nexus every 2 days with my normal usage of the phone. I'm thinking of putting a battery of the LG G2 into the nexus, to get some extra juice...

I honestly don't understand that SystemDataScope output at all. I am reading that the CPU was running at ~25% during the whole test. That seems strange. The 'powerstats-routine' process would show up in 'top' with about '0.3%CPU/0.1%MEM' usage on my phone, with peaks of '0.6%-0.9%CPU', when logging an active process.

The 'sort' command is part of the 'logging active process' implementation. You can easily get get rid of it by setting option '-p' to a high number, like '10000', or by changing the default value for the variable 'PROCESSLOG' in the 'powerstats' starter file. I will implement an option to disable process logging in the next version.

As for 'sailorgram': I was just realizing, that my power consumption would jump to a higher level, whenever I was moving outside the range of a known wifi connection. So now I found out, that the permanent 4G/3G connection of the 'sailorgram daemon' is causing this.

My developer/computer skills are not good enough to be able to confirm your observation, but the Jolla1 phone is very good, when it comes to power consumption, even when running tons of apps in the background. At least I would say so...

@mautz, I'm ordering a new mid frame housing for my N5 in red, as well as a couple of LG G2 batteries to do this same hardware mod. I wanted a backup mid frame in case I screw something up. :p

May I ask what voltages, clock speeds, gpu settings, governor and hotplug driver combination you're using to get ~2 days of usage?

Thanks!

@mautz: Would it be possible to make a kernel without that 300Hz timer rate? Is that even used in your kernels? A quick search showed me, that it should be a kernel setting.

Quote:

I disabled the 300HZ timer rate for the kernel in 1.9 and make the kernel tickless, meaning that timer changes dynamically.

Quote:

yes, there's a small power consumption trade-off...

Quote:

I would say idle battery life is quite a bit worse on the 5x but its definitely worth it like you said. Prior to March update I would lose maybe half a percent an hour and now the 5x loses around 1 - 1.5 percent an hour.

Quote:

Idle battery life affects getting through the day and not everyone lives by a charger all the time.. I used to get through the day on a single charge and now I need to charge in the evening as do others in my family with the same phone.

2nd UPDATE

We are definitely running with 300Hz with the mautz kernels! You can check that in the kernel config file in /proc/config.gz. Search for 'CONFIG_HZ'!

@mautz: So I guess it's worth a try to switch back to 100Hz. ;)

This is absolutely true for me as well. In 2.0.1.11 it was fairly good on those earlier CM builds. Immediately upon going to the later 12.1 builds and on to 2.0.2.x/2.0.4.x, the drain increase is dramatic. Sometimes as high as 1% per minute with the screen on. I commented on it in this thread and others, but it seemed to be a known issue that most were OK with as we couldn't really pin it down. I'm almost certain @minimec is on the right track with the 300Hz timer rate.

I'd like to see if we can solve it with that change!

The picture guide at the top of that post is most helpful, and that's the route I'm planning to take once all the parts come in.

Edit: I spent less than $8USD on the genuine LG G2 battery, and about $30 for the red front housing/midframe INCLUDING a new LCD, all in one piece. Both of these purchases were from eBay, domestic sellers. I did this because my existing LCD has some bad light bleed and I figured I'd just take care of everything all at once. I'll take photos of my process and put a guide together as I go, just for the sake of clarity.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview

At the moment i'm using zzmoove governor, but still testing others. But 2 days sounds much, but it's still bad. I barely use the phone during the day, with a stock installation and default kernel i get 1 1/2 days. So basically every hotplugging governor that puts the unused cores to sleep when the phone is suspended, will do the trick for me. My old Jolla 1 lasted 5 days with one charge...

I 'm trying to build a new kernel with some backported features from newer CM kernels, but at the moment the Nexus reboots directly when put to sleep or during boot or in the first few seconds after start...hard to debug :D

At this moment I'd be thrilled with over one day of battery without the 1% drain per minute with the screen on (web browsing, etc.) on Sailfish. I LOVE the OS, and the battery was pretty good in the older runs of 2.0.1.11, what changed is what's ruining the battery life I think.

We'll see what happens, but I'd be interested to see how removing the 300Hz timer thing would impact battery life. Also interested to see what you come up with regarding the backported features!

Edit: I just thought about it. The Jolla 1 used a 2100mAh Li-ion cell, where the Nexus 5 uses a 2300mAh Li-Po cell. I doubt the battery chemistry could be causing this issue, and the capacity is a little more... Oh well, we'll figure it out eventually!

I got some good and some bad news...

I've got SFOS booting with cm14.1 kernel, but it's not fully working. Lipstick is crashing on start, reboots and everything is fine. Wifi is not working, Telephon app does not start...maybe this problems could be solved...i'll first try a kernel based on CM13...

I digged a little further. Looks that on older Android versions the 'Kernel Tick Clock' was set to 100Hz. I would really love to test a kernel with these 'old' settings.

There is a long discussion here about that change. I would like to quote some posts of the discussion...

2nd UPDATE

We are definitely running with 300Hz with the mautz kernels! You can check that in the kernel config file in /proc/config.gz. Search for 'CONFIG_HZ'!

@mautz: So I guess it's worth a try to switch back to 100Hz. ;)

I'm in agreement here. We'll see what mautz has in store for us coming up. Maybe we can build a test kernel with the 100Hz timer instead, see if that makes a difference - which I'm almost positive it will.

Excellent find, @minimec! And great work @mautz! I'm starting to get excited. :D

So I set up that cross compile build environment and wanted to build a 100Hz kernel.

I tried with the 'gcc-arm-linux-gnueabi' toolchain from the ubuntu repos, but also with 'android-ndk-r13b' and 'arm-eabi-4.8'. I followed different build instructions and also tried the 'make_defconfig.sh' script, found in the 'mautz' kernel sources...

After the most painful and frustrating two hours in my whole Linux career, I had to take a break, otherwise ... https://www.youtube.com/watch?v=JtEkUmYecnk&feature=youtu.be&t=589

I can make the defconfig and run 'make menuconfig', but the building process would always fail with different error messages, depending the toolchain I use...

@mautz: Believe me... I tried... ;) Maybe you can explain me (us) your 'kernel compile work-flow' and kernel build environment. It would help me rebuild my broken ego... ;)

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview

Download Kernel v8 with CONFIG_HZ=100

@minimec

I use the linaro toolchain to build the kernel(linaro 4.9.4 with Cortex A15 optimizations) and the Makefiles contain some specific linaro optimizations flags, that could have caused the errors you have encountered. Since v8 of the kernel you have to compile it with the 'make CONFIG_NO_ERROR_ON_MISMATCH=y' option or else you'll get an error at the end of compiling.

Thank you so much. I really hope that that 100Hz will improve battery life.

Also THX for your explanations regarding Kernel cross compilation. I will give it a new try. My idea was to enable zram maybe. That would again increase power consumption a little bit, but might help 'sfdroid' users.

Again... THX for your amazing work.

Do we have a kernel package of the default installation for fallback
purposes if something goes wrong after days, weeks?

What happens if you flash the original 2.0.1.11 over it again to recover from a broken kernel, will that also wipe your data and settings?

I could easily build one, grab the original source and use the original config to build one. I could upload a build of the original kernel.

@maximillian1st

A new flash will wipe your data. But you could tar your home directory and restore it afterwards...

News from the 100Hz front.

I had my phone over 8 hours in stand-by mode (idle) over night and lost 8% battery power.

I guess we can say that this is an improvement... I am pretty happy with these results.

Settings:
I was on 'msm-mpdecision' hotplug managment, slight undervolt, 'conservative' as governor.

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview

I can confirm these observations, a great deal less power drain at idle. Still seeing the massive drain with screen on time, though. AIDA, top, lighthouse, nothing shows any crazy usage. I thought maybe it was doing something goofy with the GPU clock when web browsing and the like, so I stuck it at 100MHz for testing. Same results.

I don't really expect to get more than a day and a half total, but the screen on drain is very frustrating.

Still testing, still digging. :)

I do believe 100Hz timer is the right direction, though. Great work guys!

Re: SailfishOS 2.0 Nexus 5 CM12.1 Alpha1 | Sfdroid Pre-Alpha/Early Preview

Do you guys use multirom at all? I had read that it wasn't the preferred method a while back, so I typically do a native install. Are there any side effects or drawbacks to using multirom for sailfish alongside other OS'es?
