[i9300][2014/jun/08][TW ROMs] Yank555.lu kernel v4.2a-beta3

[xSpeced]

Hey yank, I understand that your goal with the kernel is the "just work". But it would be nice to see a optional feature to overclock GPU to note 2 level.
Something like 533 on the GPU

I would only include it if, as I did it for the old mali drivers, there is no need for user voltage raising (full voltage table in the kernel). I don't have the time atm to redo this, it's a bit of work, so if nobody else has done it, I won't go there for now.

hello yank

I Used your kernal in my device N9005 It's a wonderful, and I tried to flash your kernel in my device I9300 with temasek rom V41 but Did not work,

Can you tell me what Kernal I can use for my Device or what's the problem

[yank555]

You need to use latest OMNI beta on temasek's builds.

But the i9300 kernels certainly need a little refreshing, have been focusing more on the n9005 lately...

frandom is a simpler (thus faster) random number generator that is based on the RC4 algorithm. It's helpful in places where randomness is not that sensitive, ie, games, drawing of ui, securely wiping hard drives. It still uses some entropy from the kernel in order to seed itself. Anyway, I doubt it will make a significant difference for daily use, and simlinking /dev/frandom to /dev/random will compromise the security for ssl and other sensitive operations.

ArchiDroid uses /dev/erandom both for urandom and random, and erandom uses no entropy at all.

@Yank is right with entropy - dalvik uses it's own source. However kernel entropy is very low and actually Android for some reason consumes it faster than it's regenerating, that's why I implemented HAVEGED entropy generator in my ROM (in addition to frandom).

Passive entropy never goes below 1000 in my case, set up like this :

Because you bumped write_wakeup_threshold to 2k .

Yep, and it's passive, so no CPU load increase and no entropy quality loss

Hello Yank, there is a new sammy rom (XXUGNA5), maybe is there something to adjust to your kernel ? (anyway latest running perfect so far...)

At best, ramfs, but unlikely that would make a difference.
