Re: [KERNEL][GPL][N7][30 JAN] franco.Kernel - r42

I suggest using a file manager to delete the game, go to play store and uninstall then reinstall it and download the game again. If it still doesn't work then try on a completely stock rom to see if it works again. Or of course before that check the game settings. If after all that then you have a hardware defect and should exchange your nexus under warranty.
[Nexus 7 Original Development] sotoskawasaki:
so now that cfg is the default scheduler all that tunable options that were for row and 2048 are useless or should be still used? To be honest I dont see any difference...
[Nexus 7 Original Development] joaquinf:
just play with it and see how it compares to row and deadline according to your experience. Now i've set it to cfq/512 and everything seems to be smooth, though i have to spend moar time with it because i switched rom recently so i don't have a reference point yet.

Everything is smooth with paranoid android. I'm really pleased with my current setup :)

[Nexus 7 Original Development] davisac:
CFQ Scheduler

So I tested CFQ the same way as last time (default except for GPU @ 520).

I didn't retest all the other schedulers from r41 so it can't technically be a direct comparison with CFQ but I feel pretty confident it's close. What I did was take a few samples each of Deadline, NOOP and ROW on r42 and compared them to the r41 numbers. They were all within range I would say.

I'll update the charts on the last tab later but for now here are the results:

Full results on Google Docs
[Nexus 7 Original Development] osm0sis:
So cfq kinda kicks ass at 1024? Nice! :)
[Nexus 7 Original Development] joaquinf:
Take a second look, I think that 2048 is the sweetest spot :p
[Nexus 7 Original Development] osm0sis:
In the last test lowest is best, so really we're both wrong and 512 is supersweet except for the lower result from the first test. :p

The tunable options we used were with row but weren't for row scheduler. The tunables are for interactive governor.
[Nexus 7 Original Development] joaquinf:
daamn that's sweet :p
[Nexus 7 Original Development] murdah204:
Re: [KERNEL][GPL][N7][30 JAN] franco.Kernel - r42

[Nexus 7 Original Development] davisac:
These are the latest I think courtesy of the Gingerbread Man:

Using either Franco's app or TricksterMOD just set the values shown here.

ETA: Change g_h_l to 90 and t_l to 80.

Re: [KERNEL][GPL][N7][30 JAN] franco.Kernel - r42

I'm here as well. From the tables it looks like row @512 would be better but its being said cqf @ 512
[Nexus 7 Original Development] osm0sis:
Nah we were just talking about cfq alone. All-around winner still looks like row@512, as you say. :) I'd give deadline@1024 second place if it wasn't for the low fsync off r/w score. deadline is the most understandable/tunable scheduler though.. so I wonder if there's any way we can fix it.. ;)

Re: [KERNEL][GPL][N7][30 JAN] franco.Kernel - r42

Can anyone with Multirom boot Ubuntu, plasma or webos? I wasn't able to with r42. It gave me an error saying it required a exec hard boot kernel.
[Nexus 7 Original Development] NicoGa:
Just a follow up, and an explanation from an other source of why this benchmark is totally worthless:

http://www.anandtech.com/show/6715/...ic-citadel-for-android-devices-we-test-it-out

Better use glbenchmark or basemark ES for graphics.

Concerning the IO schedulers, seeing the variability of the results, and even if it is better than nothing, using only 3 tests for each cases seems a bit low notably for sqlite ...

Anyway thanks a lot for all these discussions and tests, and above all for this amazing kernel (that does not use the LP core!)
[Nexus 7 Original Development] firefox1337:
Guys i have been using franco kernal and love it the most out of all the kernals so far. The problem is when i change the max GPU clock or change the voltages i don't feel like its actually taking effect.

I put the max gpu to 520 ran benchmark and got the exact same score...... is there anyway to check the voltage / clock.

in franco kernal updater the status for gpu and cpu voltages show up as ?

[Nexus 7 Original Development] albundy2010:
What reason do you need overclocking? If its just to get higher benchmarks then you don't need it. Can't speak for Franco but I would bet that is why he is not including it. The device runs just fine at the 1.2/1.3 stock clocks with stock kernel. Will run better at same clocks with a faster custom kernel.

[Nexus 7 Original Development] leelaa:
Ive noticed the cpu is a little cooler, not much gain really, still a slight gain though. I suppose it all depends on what you're default voltages are for you're kernel, maybe?

When i was running moteley the other week, i think i was running 1.3ghz @980mv wich was about -125mv wich did keep my device noticeably cooler when gaming.

[Nexus 7 Original Development] Lozzo:
I know, I know. Replying to my own posts and all that. Anyway. Update..

Still suffered a SOD with the r4 kernel. Flashed it before I went to bed, woke up at 6 and zilch, nada, sod all. Had to hold power button to restart. Upon this, I flashed the stock kernel again, went to work and left it to itself. Just come back now, 6 hours or so later and bam, came awake perfectly.

Obviously there's something I'm missing which is causing me these SODs with the custom kernel. I never tried wiping Dalvik or Cache when I flashed, so I wonder if that might be the issue?

Also, read bits here and there about a "kernel cleaning script" which can be helpful when swapping and changing kernels so must remember to do some research on that. Nowt like reading up on these things and trying them for yourself, it's only way to learn rather than being spoon-fed... :D

For now, I've got a busy day ahead so going to stay stock for now, and resume experiments tomorrow.
[Nexus 7 Original Development] ridearoundsolo:

[Nexus 7 Original Development] jazzespresso:
do we need to clear caches; like dalvik, etc...etc..after we applied this kernel??
[Nexus 7 Original Development] irminsul:
No, don't wipe anything after a kernel flash.

When switching roms: wipe data and cache.

When updating rom: wipe dalvik cache, although this could be discussed, wiping dalvik won't hurt you.

When flashing kernel: don't wipe just flash.

Wiping dalvik after kernel flash only makes your first boot way longer.
[Nexus 7 Original Development] nikosrs4:
the good thing is the N7 has nice colors by default, so it's not so necessary to change them, like it is on gnexus. :)
[Nexus 7 Original Development] osm0sis:
I agree, I think the addition of a contrast control might be nice though, to counteract the IPS washout effect.
[Nexus 7 Original Development] jazzespresso:
thank you!! I was not quite sure about it, so I had to ask. If I understand it correctly, it is just simply flash it..that's all needed.
[Nexus 7 Original Development] Blades:
If there are certain optimizations, wiping dalvik is a good idea. Especially if the new kernel is compiled with a different compiler and has changes to the makefile for further optimization - not just the generic armel defaults.

I wonder when Android will be rebased (for lack of a better word) for armhf.
[Nexus 7 Original Development] irminsul:
Seriously, wiping dalvik doesn't involve the kernel. Here's _thalamus' opinion about this:

And if someone knows how android works and what it's does, it's _thalamus.

Morning all. Having a nice day so far? Good...

Anyway, another update to my SOD problems on the last page.

After getting by with the stock kernel, I flashed r6 again last night but this time, just for the hell of it, I wiped Dalvic and Cache upon flashing. And.

So far...

All good. No SOD overnight, the nexus slept as well as I did and came awake a bit quicker than I did too... :)

Upon rebooting after wiping it went through a "Android is updating. xx out of xx apps" thingamajig, I'm not sure if this is usual after wiping the above on these, I've never seen that on my other Android (albeit 2.3) devices but. Well. There we go. r6 running happily.

The only other thing I had changed in the meantime was WiFi sleep policy, going from "Always sleep" to "Never when plugged in." I'll try playing with that later in case it was that causing the problem.

Cheers!

[Nexus 7 Original Development] farmerbb:
Actually I think I figured out why MultiROM isn't recognizing franco.Kernel as compatible... I grabbed a log file from MultiROM and towards the end of it I see these lines:

[ 6.854698] multirom: CONFIG_KEXEC_HARDBOOT=y not found in /proc/config.gz!

[ 7.155065] multirom: CONFIG_ATAGS_PROC=y not found in /proc/config.gz!

So it looks like the kernel just isn't configured properly for kexec-hardboot. Francisco, can you double check and make sure that these options are set in your config file?
