Re: [KERNEL][GPL][N7][15 FEB] franco.Kernel - r47

I have found noop and cfq to be good.deadline seems to bugout My WiFi for some reason after testing. I may need to reflash the Kernel.

BTW how do you oc the GPU. Every attempt seems to be met with access denied.
[Nexus 7 Original Development] The Gingerbread Man:
Re: [KERNEL][GPL][N7][15 FEB] franco.Kernel - r47

Personally i prefer ROW (read over write)

as it generally gives me smooth scrolling and I like the idea behind how it works. To find the best one for you will require some googling to find out whats best for your requirements as they all behave different in how they handle data process

I can't see how changing io scheduler can mess up your WiFi as the io scheduler basicly chooses how data requests are handled. WiFi and io scheduler are to my knowledge unrelated and the WiFi drivers them selves are contained within the kernel its self, therefore meaning if they were messed up they would stay messed up until you changed WiFi network or changed the driver to work with the network you have. Reflashing the kernel won't help here. As for over clocking the GPU if you keep getting access denied message which (I can't say iv seen) make sure you are actually rooted then it should work.
[Nexus 7 Original Development] triggerftu:
input and out put of data depending on how it is designated to do. i know. not stupid, know how to use google compared to most people. and if there was something in the flash that didn't complete say maybe a corrupt or settings dealing with the wifi driver, than yes a reflash should work fine. as for being rooted, i am indeed rooted, i've been using CM10.1 and to test this theory used TB, root explorer, and more frequently sixaxis (my OTG cable hasn't arrived yet) all w/o flaw. w/e the case may be i'll reflash the kernel and try again.
[Nexus 7 Original Development] The Gingerbread Man:
Re: [KERNEL][GPL][N7][15 FEB] franco.Kernel - r47

Go for it then reflash and see what happens and report back, why wait?

The last bootloader I flashed was 4.13. I see a 4.18 is out now. What are the benefits of flashing this?

Is malroths's I/O script, universal for both the N7 and GNex? I just downloaded from his sig in each thread (GNex/N7) and they look the same.

Are they incorporated into Franco's kernel by default? I've got 360/3500/6/1/1 for the N7 default, and 351/3500/6/0/0 on the GNex default. The script has:

# deadline tweaks

echo 350 > /sys/block/mmcblk0/queue/iosched/read_expire;

echo 3500 > /sys/block/mmcblk0/queue/iosched/write_expire;

echo 6 > /sys/block/mmcblk0/queue/iosched/writes_starved;

echo 0 > /sys/block/mmcblk0/queue/iosched/front_merges;

echo 0 > /sys/block/mmcblk0/queue/iosched/fifo_batch;

I just updated to 4.2.2 Rasbean Jelly, so I haven't been keeping up with the latest and greatest magic.

Thanks,

RF
[Nexus 7 Original Development] osm0sis:
Not all of the tweaks in the script have been built as the defaults yet.

As for compatibility, "950io-tuna/grouper Deadline/ROW/RABS All-in-1" seems pretty clear that it's universal.

P.S. I wrote it so I know it is. ;) Where the values would differ the value in the script resolves to the correct outcome value on each device automatically.

hey guys wonder if anyone has any info on this that could help me?

i have purchased franco app and am running jb 4.2.2 with franco kernel

i have found this one problem, it happens when using tTorrent downloader and the screen goes to sleep

at that point i cannot get the screen to come back and have to long press power for a full reset restart

has anyone had this happen? thanks

now i have had it freeze on screen on downloading, hmm thats not good

is there a setting that might help?

ps i set screen "stay on" and only use home key then running applications key to go in and out of tTorrent and its holding through the download, if that means anything to anyone.
[Nexus 7 Original Development] osm0sis:
I guess I'll check out Trickster finally (feels like betrayal ;)) to try and confirm. What do you mean fine tune? f.Ku has always allowed you to edit each frequency's UV separately, does Trickster not allow that? If you're talking about picking a frequency, well that's why when you UV correctly you're supposed to set the Min/Max to the same frequency you're testing.
[Nexus 7 Original Development] FitAmp:
Re: [KERNEL][GPL][N7][15 FEB] franco.Kernel - r47

Yeah but it didn't work for me doing everyone separately, I know how to UV correctly just it would never stick. But last time I tried it didn't work, but that was awhile ago, I guess I could give another go :p

Edit: Well I gave it another go, and it even works trying it separately now, how weird.

Edit2: BUT setting the min/max to 1300 then setting voltage to low, would keep your choice for min/max but when I looked at live stats, my device was running 1000. (It like bumped it down due to to low voltage it seems.

Press thanks if I helped ~ Nexus7/ParanoidAndroid/FrancoKernel
[Nexus 7 Original Development] osm0sis:
If your screen goes off the max will reset... Wait, that's the opposite of what you said.

I just tried to UV with Trickster and it wasn't working there either... Must be something else going on here... So weird.
[Nexus 7 Original Development] FitAmp:
Re: [KERNEL][GPL][N7][15 FEB] franco.Kernel - r47

Yeah like my screen didn't even go off, was busy facebooking :p

But I UV 1000mhz by itself and that one worked... Instant reboot.

Something's definitely wrong, like you said.

Press thanks if I helped ~ Nexus7/ParanoidAndroid/FrancoKernel
[Nexus 7 Original Development] osm0sis:
I take it back, it does work in Trickster, and then f.Ku reads the correct value in its dialog. I was being a noob and didn't hit apply in Trickster before. ;)

f.Ku does write to the sysfs files so it looks like it should work, but it doesn't. Trickster even reads that number but somehow it's as though it isn't being applied from f.Ku. I wonder what Trickster does that's different to apply them... :confused:

---------- Post added at 03:37 AM ---------- Previous post was at 03:09 AM ----------

Whatever it is, Trickster didn't require root permissions for it since it didn't leave any info in SuperSU's log, then I Denied it just to make sure. It writes entries in dmesg the same as f.Ku does when it "applies" them, but only some cryptic stuff in aLogcat so I have no idea what commands it performed.

What the ****, now it's not working in either...

---------- Post added at 03:55 AM ---------- Previous post was at 03:45 AM ----------

Okay, my best guess for what's going on is that the UV interface is actually broken on the kernel side and when it crashes it's not due to the voltages, its due to the same buggy code just crapping out over a value it doesn't like, e.g. Using f.Ku to -25 all until you get a negative number will crash.
[Nexus 7 Original Development] fozzie:
Didn't Franco put a minimum threshold in the kernel to ignore 'stupid' values...so although you can set them, they won't do anything? Thought it was something like 600mV? (or maybe I'm thinking of something from the N4 thread...)
[Nexus 7 Original Development] osm0sis:
Nah that was before the last time Franco tried to fix UV here. No lower limit now. Regardless of that though, 650mV should crash 1300MHz but it doesn't. Definitely broken.

Some are having this problem myself included, it seems to be with any torrent client.

Some say its a JB bug but the only victims I have found are all running this kernel.

Not sure on a solution (except not letting device go to sleep)

Im waiting for an updated kernel and not using torrents on tablet until then.
[Nexus 7 Original Development] Erik.Leach:
I have had this problem with BitTorrent with stock kernel as well. The tablet becomes EXTREMELY laggy, and when the screen is off, it doesn't seem to respond. ***HOWEVER, with the screen off, if you press the power button to wake your device, it will eventually come back on. It takes awhile. My N7 tablet's system is simply lagging in the WAKE operation, just like it does with everything else while a Torrent is downloading.

Just pushed r48. Re-merged original hotplug driver and changed just a few lines to make it a little bit lighter. Should give a little extra power now. Also fixed the UV interface, you won't be able to input more than 600mV. Merged a few changes from upstream too. Hotplug options from my app will be gone with this driver change. Also it won't be dual-core minimum by default, will hotplug normally. I plan to re-add the options to change the hotplug parameters sometime in the future.
