Thanks Entropy, I've missed your work since I moved from Infuse over here instead of to I777-land. I do have a question, though--I note the only "nonstandard" I/O scheduler you included was BFQ. Do you find sio/vr problematic, or do they just not provide any benefit from your perspective?

I'm considering adding these - I've found that alternate governors/schedulers often cause more problems than they solve.

Thumbs up
Thanks for sharing your kernel with us i9100 users Enthropy. I really like your stability+ battery approach. Will be giving the kernel a good go.

Sorry...this kernel is comparible with jkay brightness profile?

No - And right now, I am unaware of any kernel that is. As much as I like JKay's work, I believe he lacks understanding of how screen brightness works on the I9100 and I777.

Even JKay is unaware of any kernels that support those profiles. See entry 12 in his FAQ.

To implement additional brightness steps, an additional gamma table for each brightness step needs to be implemented - https://github.com/Entropy512/linux_...ld9040_gamma.h

So until FAQ section 12 has clearly defined (and achievable) requirements for compatibility, or JKay declares a specific kernel compatible in FAQ section 12 of his mod, I won't be doing anything. Creating a custom gamma table entry is not easy as it requires a LOT of tweaking and good colorimeter hardware. Supercurio has done it at high brightness levels to my knowledge, but I don't think he's done it for low brightness levels and I don't think he's added extra gamma tables for additional brightness steps.

Edit: I have seen that Speedmod and Redpill do change the table entries for the lowest two brightness settings - however, they don't add any new bins, so the brightness change is achieved even on JKay profiles that don't supposedly require kernel support. e.g. JKay's "dark, requires kernel support" are pointless because the only kernels that actually provide dimmer minimum backlight do so even with his profiles that don't claim to require custom kernels. (And the "super dark" and "dark" profiles will behave the same regardless of kernel.)

What's interesting is hardcore did it for only two of three available panel types. Either two of Samsung's panel types are brighter than others, or hardcore did this without testing on some panel variants and just thought "the numbers are different, I'll change them". I'll look into playing with this as it would be nice to have lower minimum brightness, but it's somewhat low priority as it's easy to simply make things look like **** if you're not careful.

its possible to make your kernel fully compatible with the cmw manager of chainfire
for now some fonctions are desactivate
anyway i m testing it now and all seems to be good

So far so good mate.
Batterylife we will see in a day or two but all in all running fine.

Thanks and go ahead with ur work.

CHEERS ;)

Others have asked me this - if he has compatibility guidelines posted somewhere, I'll take a look at them.

Battery in deep sleep is exceptional, 2% lost in 5 hours with WiFi enabled and emails syncing.
