I haven't had a single wake up issue since setting hot plug suspend mode to 'hotplug suspend' over twenty four hours use now :good:

BTW I'm also getting nice results using alucard/slim/slim/alucard - the way I assess its usefulness is by running usemon to watch the graphs of each individual core activity plus real life feel and battery consumption, what I see is smooth constant frequencies on cores 1 and 4 (alucard) and spikey on cores 2 and 3. now to my mind this is good because it means device is very responsive when needed (course 2 and 3) but battery conserved with alucard in 1 and 4 with consistent low frequencies. Watching battery consumption is good for me comparatively with same sort of usage. Now please don't shoot, I am not an expert by any means and my assumptions are based on what I can see and feel rather than any technical knowledge and I could be completely wrong, don't know, but it seems to work good for me :). The only other changes I made from default is io fiops and read ahead ext 2560.

About the Bluetooth stutter: I found settings in Poweramp yesterday : /settings/audio/advanced tweaks and whilst stutter occurred I set audio buffer size to 750 which stopped the stutter without having to kill Poweramp however i still got some crackle so I set audio thread priority to normal which stopped the crackle and everything sounded nice. I have not tested thoroughly but no stutter for about an hour constant listening screen off and also screen on and multi tasking.

Hopefully Kantjers recent findings for settings in slim code will finally put this matter to bed though ;)

[MENTION=3678806]soza971[/MENTION] I am getting great results with alucard/slim/slim/alucard

I have also just switched to Kantjers settings on post #7 with the above changes to governors (Kantjer uses alucard/alucard/slim/slim) I'm not sure if there is that much difference in performance with different governors in different cores, it's probably just personal preference. I like slim in core 1 and 2 because the device feels very fluid and when I look at the stats they look nice.

I also switch mc_sched=0 because that is better for Bluetooth audio.

I also keep fsync on

Question regarding Bluetooth drama..

Did you ever uncheck the Auto OOM in Alucard?

If you do, you'll need to reboot.. But this will reset the oom/lmk values stock.. Which (as I discovered a few days ago) seems to be another major difference between Alucard and Googy..

Hangouts vs SMS

what is more efficient or more better than the other?

Not how the programs work but rather the network connectivity and OS resources that goes into construction and display of the messages.. Any ideas?

Thinking about Googy going to a Windows phone.. They don't have hangouts.. IPhone has their messages app which is tcp and sms integrated..

Thanks in advance.

Hangouts needs Google Cloud Messaging (GCM) so wakes the phone too much for me (plus I don't use hangout's, everyone I need is on Whatsapp)

[Galaxy S 4 i9505 Android Development] Swizzy88:
Has anyone done any testing with number of cores vs. Frequency?

Since lower frequency means lower voltage i figured the battery savings would be quite noticeable but they werent as far as i can tell. Has anyone tested just running 2 cores at maximum frequency and compared battery performance?

Is there a formula i can use to work out if 2x1.9ghz uses more power than 4x1ghz?
[Galaxy S 4 i9505 Android Development] FPSUsername:
For me would be:

2x1.9GHz = 2 x 1150mv (1890MHz) = 2250mv

4x1GHz = 4 x 925mv (1026MHz) = 3700mv

(note that this means the ammount of mv used when cores will be running on max speed and I use alculards voltages, which are lowered).

It is better to turn off cores instead of slowing them down. When you slow down the cores the phone will become slow.
[Galaxy S 4 i9505 Android Development] __NBH__:
That is what I was thinking but 4 cores at 1ghz will complete the task faster than 2 at 1.9ghz ( only very slightly though) and would use more power.

I did a test with KT kernel using low frequencies but all 4 cores active, the phone was laggy and didn't save any battery. It's better to try and do as much with one core then turn on another if required which is why the up threshold for governors is something like 70 or 80 percent.

[Galaxy S 4 i9505 Android Development] s3icc0:
Hi I think this is the proper thread to discuss:

I was thinking to tweak the Alucard hotplug parameters and I am not aware about all the parameters:

hotplug_freq_x_1 - the frequency at which the other (instead of x the # of the core) core is hotplugged in - turned on (probably based on the frequency of the previous core or core 0)

hotplug_freq_y_0 - the frequency at which the other (instead of y the #-1 of the core) core is hotplugged out - turned off (again probably based on the frequency of previous core or core 0)

hotplug_load_x_1 - the % of load of the core (instead of x the # of the core) the frequency for the core is scaled up

hotplug_load_y_0 - the % of load of the core (instead of y the #-1 of the core) the frequency for the core is scaled down

hotplug_rq_x_1 - treshold run queue length for core x to turn on (not sure what the UINT means)

hotplug_rq_y_0 - treshold run queue length for core y-1 to turn off (not sure what the UINT means)

the rest is clear, but I am still not sure about these parameters. - what the are related to and for some I completely don't understand (like the run queue - for which I googled but now I don't know why there is on and off parameter).

Summarized:

hotplug on frequency is related to core-1 (previous core with lower number)?

hotplug off frequency is related to core+1 (following core with higher number)?

hotplug load on % is related to core-1 (previous core with lower number) or to itself.

hotplug load off % is related to core+1 (following core with higher number) or to itself.

hotplug rq on - what the heck? :)

hotplug rq off - what the heck? :)

hope someone understands my question - really tried to google hard for answer but not successfully
[Galaxy S 4 i9505 Android Development] Jsilver73:
Yes, I think this is definitely the right place to discuss such matters so we can all learn to tweak Alucard kernel better :). Unfortunately what you are taking about is right over my head ATM although I am keen to learn and really hope there are others here who can help ;)
[Galaxy S 4 i9505 Android Development] s3icc0:
And here some parameters I am using - these should be helpful on all 3 types of kernel (I am using default frequencies and voltages):

cpu_down_rate=2

changed from 5 to 2 to scale down faster

cortexbrain_read_ahead_kb=256

more read - ahead … better for bigger files - I do a lot of photos and coying from/to sd cards

internal_iosched=row
sd_iosched=row
internal_iosched_sleep=row
sd_iosched_sleep=row

Read Over Write scheduler … personally love it as usually I do more read things with the phone and I don't feel any loss of speed when using camera or copying files, it is also safer then CFQ e.g.

gpsregion=Europe

changed to Europe as I am from Europe … change to what suits you

init_d=on

enabled to allow init.d scripts

logger=on

enabled to allow all the system and kernel logs for debugging

pwm_value=50

I don't like too much haptic feedback … and it saves a little battery (at least I hope so)

force_fast_charge=1

I love the fast charging from USB and with latest kernel version it does not disable access to Internal SD … so why not :)

Dyn_fsync_active=0

dynamic fsync disabled - (I was facing some lost of data in the pass and I don't personally trust this function)
[Galaxy S 4 i9505 Android Development] wyzli:
Ok I'll wait :)

Thanks
[Galaxy S 4 i9505 Android Development] kantjer:
My thoughts.

hotplug_freq tells extra CPU cores when to scale up or down based on the frequency of the lower numbered CPU (like you mentioned)

hotplug_load tells extra CPU cores when to scale up or down based on the load of the own CPU

hotplug rq tells extra CPU cores when and how many to scale up or down based on the length of the run queue (processes waiting to be serviced by the CPU), only the "uint" is not clear to me (I understand it can only hold positive values but thee it stops for me)
[Galaxy S 4 i9505 Android Development] s3icc0:
Similar thoughts ...

About hotplug run queue length I found it is the time reserved for each process in the queue ... which makes sence when you have only one value for each core (so cpu 1 is set for 100ms -> not enough -> cpu 2 200ms (longer time not to waste energy required to power it on) -> not enough -> cpu 3 400ms) (maybe not miliseconds but cycles, what I know). But then when you look into stweaks and on the description it really looks like it is the number of processes in the queue (uint for unit-integer?)

Anyway it will be really helpful to explain each parameter to users in the OP so they know what will happen when they tweak some ...
[Galaxy S 4 i9505 Android Development] Jsilver73:
