You mean that we need to install an extra application just to keep your kernel manager updated?

Why the HKM can't get updated like all other apps in store?
[Nexus 4 General] spider623:
My best bet it's not his app
[Nexus 4 General] acejavelin:
Works well, kind of slow but this is probably because of the update source... Would be nice to be able to pick an alternate update source or mirror, I see an option in settings but you have to know the server and path (?)

One other small thing, you can't "back" out of the app, pressing back just stays at the main screen. you can of course go Home or switch tasks to something else.
[Nexus 4 General] hellsgod:
No, to keep the kernel updated ;)

hells
[Nexus 4 General] themike10452:
First: The update source is something related to the host where the app checks for updates, which is managed by hellsgod. I created this switch just in case anything unexpected happens so we can switch easily to another update source. Or maybe later created a dedicated source for beta/unstable releases ...

Second: The back button thingy is there to prevent you from killing the main activity of the app, thus corrupting its work. You can always use home + clear from recents. I will make a change concerning this part.

This app updates the kernel and not HKM, HKM receives updates from PS just like any other app. I created hellsCore U2D so that hammerhead users can benefit from it, seeing that HKM will not fully support nexus 5. In the future HKM and HU2D will be 2 cooperative apps to provide you the best tweaking/updating services ;)

Hi, i found one bug in your aplication.

I tested in miui device mako installing the kernel but seems the APP download the N5 version

I open the zip file and check the update script

#updater-script by show-p1984

set_progress(0.01);

ui_print("-Checking Model ID");
assert(getprop("ro.product.device") == "hammerhead" || getprop("ro.build.product") == "hammerhead" || getprop("ro.product.board") == "hammerhead");
ui_print("-Success!");
ui_print("-Model ID - Nexus 5 (hammerhead)");
ui_print("-Ok to proceed");

Can you point to n4 miui compatible kernel?
[Nexus 4 General] [zozi]:
The miui rom have 4.4.2 base i flash your kernel b58 and now i dosent have wifi... :( i have tried before and i have te same error no wifi thats why i download from the update app :( i cant solve this :(
[Nexus 4 General] hellsgod:
If there is a flashable zip around for this problem (mostly called wifi fix) then you can use my kernel. I won't make a 3rd kernel for mako, just because the guys from miui won't update the base...

Hi,

I'm on b57. When I take pictures, most of of the time camera will freeze, then blank black screen, and few seconds later phone will reboot into Google logo screen.

Any kernel settings to fix this behavior?

thanks,
[Nexus 4 General] hellsgod:
I've added some camera fixes some time ago, but even this couldn't fix this issue. I've read about that issue on my kernel and on some others. This can even happen on stock kernel. I don't have a fix for that atm. My test device doesn't have that problem, so its really hard for me to get it fixed, sorry.

hells
[Nexus 4 General] ch-vox:
unfortunately, this happened to me with your kernel. that was THE point that made me go back to stock.

with stock, I've never had this (really problematic to me) issue.

I often use Nexus 4 camera almost everyday, and this only issue is really not compatible with my usage.
[Nexus 4 General] hellsgod:
I haven't had any commits for the camera and it happened. Then I added some commits and it still happens. For the moment I don't have a fix. I even don't have a hint where I should look. I'm only getting reports. But reports won't fix that problem. Maybe a log would give me a hint in the right direction. Because it doesn't happen on my device, I can't get a log from mine.

I've uploaded b59 in the test folder on dev-host. You'll not be able to download it through the app, because its an experimental build. We don't have a flag for it, so to prevent users from accidentally flashing a test build, you'll only find it on dev host in the test folder: dev-host If you'd like to know what's in it, you have to check my git. I don't have a cam fix, just fyi ;)

Let me know what you think about it, if we're on track or not :)

[Nexus 4 General] Matrixie:
The whole Nexus 4 camera bug is really very strange. It seems that each user experiences it differently. Personally I find Hell's gives me a much more stable system (camera-wise), I get about 1/3 the amount of crashes stock kernel gave me.

Gradually over time they seem to get more frequent, then when I clear data and cache of the camera app they get less frequent again.

This Google groups thread shows just how varied the issue is for everyone:

http://code.google.com/p/android/issues/detail?id=67113

Fingers crossed Android L will finally address this issue.
[Nexus 4 General] Lazy Rich:
I think we are back on track now :D

After b57 and b58 felt worse for me, this one is as smooth as b56 was.

Anything else we should test?

[Nexus 4 General] hellsgod:
I think it was the aggressive scheduler battery saving value of "sched_mc = 2" which caused some hiccups. Since its broken and really messed up since ages, I've removed it. I've added some power efficiency patches from nvidia, which maybe doing a better job than shed_mc. So more smoothness but still some battery saving. An interesting part will be what that all means for battery life :)

I don't know. Lets see how b59-v3 behaves. You can flash it like a regular build, so you don't have to wait for the final one ;)

Here's the changelog in text form:

Changes since b58:

-merged some patches from nvidia for a better power efficiency (could save some battery)

-arm: lib: Using hard-float (maybe some little performance gain)

-reverted the arm topology (to merge a newer version of it)

-merged new arm topology (more efficiency)

-added a sysfsinterface to enable and disable gentle fair sleepers (disabled by default - maybe improves UI smoothness)

-added a sysfsinterface to enable and disable arch power (disabled by default - could give some more efficiency by screen on, but drains more battery in standby)

-removed sched_mc (because its broken since forever and nobody really cares to fix it)

-cpufreq: hellsactive: removed unused boostpulse interface

-cpufreq: hellsactive: the governor now jumps only to two phase freq if cur_freq >= hispeed_freq to avoid unnecessarly jumps from min_freq (could save some battery)

-scheduler patches from upstream, some backports from faux (could improve battery under heavy load)

-mm: Adjust dirty writeback for IO boost (maybe drains some more battery, but could improve IO)

-fs: dcache: set vfs_cache_pressure 40% (maybe some little more IO boost)

-some new compiler voodoo (could improve overall performance, smoothness, efficiency...)

-some other little things here and there but not so important to mention...

As you see, there is a reason I did these experimental builds. Many changes ;)
