[MOD] BlackenedMod v2.0 (Pixel 3a / Pixel 3a XL)

[Giocarro]

So, I took the plunge and installed this script.

So far so good, device is quick but will have to test a bit more before giving a feedback.

Two questions:

1) how can I know whether the script got executed or not?

2) I'm more a performance guy rather than a battery guy, so I'd like to know if editing the script and changing the schedutil "hispeed_load" parameter from 60 to 50 for both clusters does make sense or not.
Is there any other tweak one could apply to gain smooth and stutter-free animations everywhere?

Thanks in advance!

Look in sdcard\logs folder for blackenedmod.log file to see if the script got executed.

1) Check what the guy above me wrote.

2) Changing hispeed_load to a lower value will make the CPU using the "desired" frequency more and close to avoiding using the rest of the frequency steps (which is a thing that's neither good or bad from a power consumption point of view - it depends all on what you prefer on a personal level.)

 

[Giocarro]

On a personal level I prefer higher frequencies to have better smoothness and performance: is hispeed_load the correct setting to tweak or not?

Yes, it is. Try play around with the Schedutil rate_limit tunables also, for better control over the scaling across the frequency range of each cluster.

@xFirefly93 thanks for your suggestion!

Starting from an excellent script I tweaked just two parameters to gain more speed and I think that it is working, sacrificing a bit of battery life obviously:
hispeed_freq = 30
up_rate_limit_us = 222

Now, during night time (with AOD set to always ON) battery drained 11%, which is quite a bit so I guess I'll have to play a bit more to find the right balance between performance while using the device and power consumption when the device is idle.

That said I have one more question for you: do you think that it makes sense to lower the "swappiness" value from 100 to 10 or so, always in the direction of gaining a bit of speed? I think that Bonito and Sargo do suffer just a bit of slow eMMC storage and if I understand swappiness a lower value should make the device read and write a bit less. Is it correct or - maybe - it is not something noticeable at all?

Cheers!

Update!

Note: It is recommended that you reboot your phone after you have applied v1.7 so the customized changes / improvements takes full effect and is fully up & running as intended.

Version v1.7 (Major release):
- Finally fixed the battery life issues that a few may have experienced while having BlackenedMod up and running
- Included a simple guide on what you've to do for getting the alternative min & max frequencies working as intended
- Disabled power efficient workqueues once and for all (the overhead cost doesn't justify the notable performance loss)
- Re-configured my Schedutil profile from scratch so it works like a bulldozing charm together with the changes below
- Increased Schedutil up_rate_limit to 1000us (reduces any overhead caused by all over the board frequency scaling)
- Unlocked & enabled the 300Mhz freq for the big cluster
- Slightly underclocked the big cluster max frequency for better battery life power and for a better user experience
- Carefully adjusted the min LITTLE cluster freq a little for compensating for the new big cluster min & max frequencies
- Reverted commit sync interval to default 5 seconds again
- Some additional minor fixes and adjustments here and there

If you optionally want to donate a beer or five as a way to show your appreciation for all the dedicated hours and work that I am putting into this mod on a daily rate - then this link is the way to go!

Enjoy!

I've noticed even before this update if i try setting any big or lil cluster lowered to 300mhz it would start making crackling noises in games. Is it ok just to revert back to regular cpu frequency without messing with all the new updates?

Ofc, it is

Alrite thx. It did fix it tho ?

 

[Giocarro]

Thanks @xFirefly93 for the new update!

Installed 1.7 release, so far so good.

Still wondering whether I should twek a couple of parameters to spice up performance a bit; specifically I'd lower a bit these settings:
- hispeed_freq
- up_rate_limit_us
- swappiness

I know that the script aims to be balanced, but I always care to tune toward performance rather than battery.

Isn't the current releases version great enough on the performance for your needs? You need even more?

This script is perfect for 99% of people, but I'm a bit demanding and my bench test is always the side menu of Play Store: still have to find a way to get it perfectly smooth, other than setting everything to *performance*.

Now that I think about it, I might try to set up some kind of per-app profile and boost just Play Store... ^__^

If you want to, I can send a user customized version of v1.7 to you over at Telegram?

 

[Giocarro]

That would be too kind of you!

But wouldn't it make sense to share it here, maybe under a different name, like "SpeedDemonMod" profile?

^__^

We'll see what I may come up with for you at Monday the next week

Note: It is recommended that you reboot your phone after you have applied v1.8 so the customized changes / improvements takes full effect and is fully up & running as intended.

Version v1.8 (Minor release):
- Re-wrote and "patched up" the whole script from scratch
- Removed all the modified frequency stuff for now (needs a few more adjustments before they will be added again)
- Re-enabled power efficient workqueues (=PEWQ) again
- Fully enabled laptop_mode (slightly improves battery life)
- Disabled fsync per default (improves IO performance)
- Cleaned up a few crucial typos both here as well as there

I don't know what was causing my battery drain on 1.7 but it would go from a hundred and then go down by 2% until it reached 89 which would then start draining by 1% but now the battery draining normally plus it give in accubattery its giving me better battery life.

How much better compared to when running without BM?
