Root [STOCK][LINARO 4.9.3] Volt Uno v3.3

[bg4m3r]

The newer UNO kernels however never worked with swap.

Just curious how you determined this? I was just thinking, with needing the delay, maybe that's the issue with the newer versions?

I tried manually enabling swap and got insta-crashes. I also seem to be getting random reboots with swap on 3 and 3.1, I'm not sure what is causing it

I'm just running swap on stock kernel using what features it has... Running well enough.

If someone can grab /proc/last_kmsg after a reboot caused by swap on the latest version it will help get swap fixed.

The following pastebin link is the /proc/last_kmsg log I got trying to use swap on volt uno 3.1 (voltunov3-1.img)

I have been busy with work but I also started to get random reboots I ended up switching back to the stock kernel but I have a feeling I'll be flashing back to Uno but I do see a performance gane with swap enable

You guys made me think it was something I was doing wrong with the Uno kernel regarding swap lol

 

[dvdavid888]

Sorry about that I haven't had any free time (work and kid's)as soon as I get some free time I would like to tinker with swap maybe try to get it going

It used to work fine...
It's got to be that we're on zv6 and it's a zv5 kernel.

 

[dvdavid888]

I had swap working perfectly at one time also

It never worked for me with Uno 3.1 or earlier on zv6, zv5, etc. Stock was it

Well, good and bad news. Bad news is there's no crash in that log. Good news is that there may still be a clue. Log shoes the kernel was compiled with Linaro GCC 2015.03 - Cortex-A15. This is an issue because the 8926 doesn't use krait/A15, it uses a cortex-A7. The kernel will be compiled with instructions our cpu doesn't understand. Whoshotjr2006 needs to switch to A7.

He hasn't done anything with this in a long while... Might be up to someone else to do it. I'd give it a try if I had the slightest clue as to where to start.

I can give it a go in a few hours

If you are going to try a compile, could you add in "binfmt_misc" support? I wanted to mess around with the linux deploy app that apparently has a compiled qemu and some scripts that make use of binfmt to run x86 and x64 apps on arm. I know it will probably slow as molasses but something cool to try.

Looks like I can. Fingers crossed it doesn't break anything.

@spock1104 On IRC? I'm on freenode under the same username right now at ##LG_VOLT

For a good starting point, I wrote up a guide on a different phone: [LINARO] AWEstruck v1.04 12/14/14 | [3.4.107] v1.05b6 5/30/15

 

[spock1104]

I built but ended up in a boot loop, I'll give it another try tomorrow

 

[whoshotjr2006]

The last time i compiled this, it was generally accepted that the linaro cortex a15 gcc branch held all the optimizations already for the a7. Things may have changed since that time as i have not kept up on the project, but its what all our sister devices were using so i went with it.

I used a modified defconfig for building the kernel, the answer is probably in that.

 

[spock1104]

Yeah the A7 vs A15 is a shot in the dark right now, it's the only inconsistency that stood out in the log. A last_kmsg with a kernel panic logged will be ideal for troubleshooting

I figured out my boot loop, I apparently can't optimize the build (yet). Working test build for now: http://www.mediafire.com/download/jbaz45cehrd1fl3/uno_49.zip

 

[spock1104]

so here's the thing, to really optimize CONFIG_CC_OPTIMIZE_FOR_SIZE needs to be unset, but when I do I'm stuck at the LG logo

spock1104 So the build you just linked us to is OK for testing I don't mind reboots or a boot loop just dont want to fry my phone and buy the way thank you for all the hard work you do. my ZTE Awe is still running like a chap

Yes, the one I posted is OK. Used Linaro 4.9.4 to build, with Os optimization.

Yeah Spock has been at this for some time lol. The Awe had more roms than pimps have rims!!
