[Kernel][5.1.1][P600] Xluco Kernel - Z1 [17/11]
- Thread starter xluco
- Start date
Neither the ramdisk or anything in the kernel has changed from stock regarding mounting of anything. Try reflashing stock rom with odin.
It seems 0.2 is pretty unstable. Probably best to go back down to 0.1 for the time being.
Is anyone else getting logs full of "unregisterIRListener() is called"?

I did and now it worksGoing to try OC now
Phew, good to hear, would hate to think id bricked someones device
Does this kernel work with the hashcheck 4.4.2 ROM ?
Edit flashed the v2 version and seems to be running great with hashcheck ROM - but the overclock doesn't seem to be working - testing out a 60 MV undervolt now - thanks for the great kernel !!!

Thank you again for the kernel and sharing. I have found that 2.1 is unstable even with increasing the voltage. The 2 GHz mark needed a slight boost in voltage and it works just fine now. I use trickster mod which is a free download by the way.
The maximum voltage is 1387 so setting anything over that won't do anything ill up the limits for the next version but l'm not sure how high to push it
l have to make some changes to the ramdisk to make OC Stick. didn't want to do it in this version in case people found it wasn't stable enough to boot
I did and now it works
Im having the same problem with cant mount cache, which stock rom did you use? scroslers? then I assume just installed the rom and kernel again?
v0.3 in the OP
Long changelog so ill post it in the morning. Lots of fixes and power efficiency tweaks

CleanRom is 4.3 and this kernel is for 4.4.2 so it will not work.

Just flashed this now, everything seems to be good.
Thanks for the update :good:

Yes, I realize that, but scrosler also has stock 4.3 firmware on his site to odin which is what I was talking about, I resolved the issue, twrp 2.7 was the cause.
Just flashed v0.3 and it is great makes this tablet much quicker then stock seems to be as fast as my 8.4 pro with the snapdragon 800 now thank you !!!

I just want to report that 0.3 is stable and fast for me. The only thing that is bothering me, is the lag I am having with nova launcher the first time that i swipe through home screens. I had this with the previous versions too but not with stock kernel. Also if I swipe using the stylus there is no lag at all. Is it maybe because of the digitizer thing that you disabled? Can you make a test version without that commit?

Hi guys,
I compiled a kernel from the SM-P600 Lollipop sources for my personal use and thought I'd share, since there doesn't seem to be much kernel dev going on here. I want to make it clear that I'm not a programmer or developer, I just like to tinker.

Added tonnes of build optimisations (in a much more sensible and stable way than V2), a couple of big filesystem improvements (EXT4 should be much faster now and supports FIDTRIM), I was feeling generous so I added the conservative governor, SIO, ZEN, BFQ and FIOPS schedulers. Disabled verbose debugging saving 70k from the kernel size.
I also gave the OP a quick refresh, the feature list now reflects accurately V3-B1 and onwards, stock kernel has been added to the second post if anyone wants to revert at any point
---------
I've added a few patches to V3-B1 from @UpInTheAir's kernel to do with how HID handles keyboards and mice, let me know if that improves anything10
I've had problems trying to update standard governors like interactive and ondemand though because they are heavily modified (for the big.LITTLE architecture, I'm presuming), but I'll certainly take a look
Edit: just a quick note to say I'm starting on V4 today Using the slightly updated kernel sources (P600ZCUCNE3, as opposed to P600XXUCND3 which the previous versions are based on). I'm going to investigate a simple solution for tweaking the kernel, maybe look into writing a simple app or something8V3-B2

Lots of SLUB improvements, NVIDIA's power efficiency patches and fixes to unaligned access.
I haven't looked at the smartscroll thing or keyboard thing yet so they're still in the same state they were in the last build.
EDIT:
Also a note that turning cores off doesn't save battery, turning cores off and on under load uses more battery than just having them on, you can tweak the governor settings though to keep them at a lower speed more of the time, that would save you more battery than turning individual cores off. It's also a bit more confusing because of the big.LITTLE architecture I think.
I did look into the 'true octa-core' patch thing that was posted in the general section, but the three patches refer to files that don't exist in this kernel, so thats a no go also.
