I don't know if the Linux Kernel makes use of it but Ofast seems dangerous in my eyes.

This along with other optimizations gets activated:

-ffinite-math-only

Allow optimizations for floating-point arithmetic that assume that arguments and results are not NaNs or +-Infs.

This option is not turned on by any -O option since it can result in incorrect output for programs which depend on an exact implementation of IEEE or ISO rules/specifications for math functions. It may, however, yield faster code for programs that do not require the guarantees of these specifications.

The default is -fno-finite-math-only.

-fno-signed-zeros

Allow optimizations for floating point arithmetic that ignore the signedness of zero. IEEE arithmetic specifies the behavior of distinct +0.0 and −0.0 values, which then prohibits simplification of expressions such as x+0.0 or 0.0*x (even with -ffinite-math-only). This option implies that the sign of a zero result isn't significant.

The default is -fsigned-zeros.

Maybe the Linux Kernel has force disabled this in every file that needs signed fp zeros or NaN/Inf results. Then it would be safe for sure.

But lets be real, has anyone noticed any real speedup by the step from O2 to O3 (on certain code and architectures O3 is slower btw)? Has anyone noticed any real speedup by Linaro (besides memcpy benchmarks)? I am not a huge fan of those optimizations tbh., I mean even the normal GCC ****s up sometime (eg. gcc 4.7 & memtest, quite a lot of linux isos fail the 7th test).
[HTC EVO 3D] helicopter88:
Didn't mean to start a GCC battle here!

I was just asking if he's using Ofast or O3

I know optimization flags can be very dangerous,but so far I've got a small boost in speed(noticeable under heavy load) and not a single crash
[HTC EVO 3D] NamenIos:
Did not want to start one ;) just warning about to much optimizations. O3 should be safe and not produce any instabilities on paper, just bigger executables. With OFast I am not so sure. Linaro had had some bugs leading to unstable binaries in the past iirc, but usually they get noticed and fixed relatively fast in new versions.

Current uptime 26 hours and no reboot and running good, but I had the reboots very seldom even before.

btw. I just noticed foul words get censored, funny. As almost my complete English language socialization happened through tv and movies I swear like a sailor and in the back of my head assume everyone does.
[HTC EVO 3D] 1ackass:
Ermm bigwillyg could you remove the camera driver settings? With the camera driver setting there is a huge zoom lag(when I try to zoom it won't just zoom, until I take the picture) in cm10 :S , but the versions without camera settings had it fixed.
[HTC EVO 3D] Conny:
14,2 no reboots so far. 14,1 and 14 few times a day
[HTC EVO 3D] bigwillyg:
That's odd. Can you get me a log?
[HTC EVO 3D] 00mpollard:
14.2 is great on mwakious Rom :D
[HTC EVO 3D] 1ackass:
there you go ;) -
[HTC EVO 3D] bigwillyg:
When there were no camera settings in aroma it was using sense drivers by default unless it was manually changed in the 99buttered script. Are you choosing the aosp drivers? If so we're you doing that back with the older versions?
[HTC EVO 3D] 1ackass:
I used the aosp cam drivers, but I will choose the sense camera drivers next time.

EDIT.Okey I used the sense camera drivers and it works now! Thanks bigwillyg :)
[HTC EVO 3D] ankabo:
What is the difference between htc and aosp-cam drivers?

Gesendet von meinem Evo 3D GSM mit Tapatalk 2
[HTC EVO 3D] 9m2bal:
Use htc cam driver if you are using sense based rom, and choose aosp cam driver if you are using non-sense (closed to aosp) like cm rom.
[HTC EVO 3D] ankabo:
OK, thanks for answer. So it depends on the used rom and I installed the correct one ;)

Current version offers continuous reboots, used recommended settings and was not able to use my ROM again. Luckily had a backup, but I'm somehow fed up with the reboots I randomly get (especially while calling during data usage) - can anybody recommend a more stable kernel? Anryl maybe?
[HTC EVO 3D] dido_23:
It's my first time to use kernel so what is tha best app to use it with this kernel is that kernel tuner I think ?

And how can I know there is an update for this kernel it use OTA updates anybody can help me with that :)
[HTC EVO 3D] fernavil:
+1 return 14.2 not reboots
[HTC EVO 3D] SecUpwN:
Once you flashed 14.3, you cannot return - even with flashing 14.2, ROM keeps bootlooping. Great sh!t.
[HTC EVO 3D] fernavil:
Now 14.2 no problem, wipe caché + dalvin and flashed
[HTC EVO 3D] bigwillyg:
Actually the sense drivers also work for agrabren's newer cm10 and any room based on it. The aosp drivers are for the roms based on his older cm10 or that state they are using aosp camera drivers.
[HTC EVO 3D] bigwillyg:
Kernel tuner is a great app to use.
[HTC EVO 3D] bigwillyg:
Please thank this post if you are having booting/rebooting issues with 14.3 so I can get a head count.

Do not thank it if you are fine on 14.3.

You would need a Rom that supports it.
[HTC EVO 3D] dido_23:
Thank you for quick reply
[HTC EVO 3D] bigwillyg:
those that are having reboot issues on 14.3, can you please try and get me a log so I can see what is going on? in the mean time I will rebuild the gsm kernel and upload it again just incase something happened.
[HTC EVO 3D] bigwillyg:
I recompiled and uploaded 14.3 again just incase it was a bad build or upload. Please try it again. if you are getting reboots please try to get a log and provide your setup info. also please check any rom scripts in init.d or the qcom.init.post_boot.sh (if any) that may conflict with the kernel.

and if you get any kind of issue with the camera, flash the kernel again and choose the other camera driver.
[HTC EVO 3D] MMarv:
I've been using 14.3 since yesterday and it works great for me. More battery friendly than previous versions, it seems. I have had no reboots by now. Thanks:good:

Merry christmas!
[HTC EVO 3D] pavel54:
There are 2 options on installing rom, on kernel based mpdecision:

"Kernel manages the hotplugging" ------> maybe this causing random reboots.

"Rom ........................."

If you ask why i think that, i was using the rom with kernel and set "rom manages the hot plugging" for 2-3 days (14.2) and there was no random reboots, yesterday i was tried second option and i was had reboots for every 10-15 minutes, maybe i'm wrong and i was missed something but if someone can check that thing too that will be clear,

regards ;)
[HTC EVO 3D] bigwillyg:
If that option is enabled you should manually check to see if mpdecision and thermald have been renamed or deleted from /system/bin
[HTC EVO 3D] jcsy:
Billy,

On OPPA GANGNAM CM10 ROM (18 DEC 2012) with 14.2Butter toast

FIRSTLY

stock kernel = no super user issues

your kernel = super user issues

what I mean by super user issues?

launch any app requiring SU, permission request pop up, allow/deny, allow (remember)

and permission pop up keeps popping up 5-6 times as if it doesnt get the access

also, what happens is that its as though SU doesnt go thru properly;

eg:

Launch Titanium Backup, permission pop up, allow, Titanium says GREEN TICKS OK

more permission pop up, allow, continues thru the application

perform a SU related instruction, such as DISABLE app

no SU error

SECONDLY

data drops

i need further testing but over across for 2 days I flashed this ROM, i got data drops

data icon shows EDGE, or HSPDA or 3G

initial browsing is ok , however after screen off, deep sleep for 30-45 minutes, data drops and the icon remains :D

I've flashed back to stock and FIRST issue seems to have gone away, however I need 1-2 days to see if data drops persists for the SECOND issue
[HTC EVO 3D] bigwillyg:
Can you get me a log?
[HTC EVO 3D] jcsy:
which log and how would you want it from?

alogcat?
[HTC EVO 3D] bigwillyg:
Alogcat would help, you can also find a kernel log at /proc/last_kmesg with a file browser.
[HTC EVO 3D] jcsy:
ill get them 2 u later, now is christmas eve and testing whether data still drops

then both issues will be confirmed :)

if not, it could very well be ROM problem that causes data drops
[HTC EVO 3D] dingnangen:
I found your kernel's minimum screen backlight is brighter than the other such as anryl .why?
[HTC EVO 3D] bigwillyg:
I will double check the brightness level but I'm pretty sure I have it set just like Anryl.
[HTC EVO 3D] dingnangen:
I am using 14.2. ROM is cool v11.
[HTC EVO 3D] 9m2bal:
Latest one is 14.3. You should try it and give feedback.
[HTC EVO 3D] dingnangen:
I try it and the same in 14.3.:confused:
[HTC EVO 3D] 9m2bal:
You can change the backlight brightness (normal/lower/lowest) in Leedroid Tweaks. Under 'Misc' tab if not mistaken.
[HTC EVO 3D] jcsy:
Regarding my data drops and SU issues

data drops happen even with STOCK KERNEL on OPPA GANGNAM CM10 ROM

not sure if you're willing to help in that area, lol

since the ROM was made for CDMA, and nobody seems to report data drops in CDMA there though

regarding SU issues, when I flashed stock kernel over again, and used apps requiring SU permissions, they seem fine

now i flashed BToast again and the issue seems to have gone away

maybe a bad flash or something went wrong there :)
[HTC EVO 3D] SecUpwN:
Is it just me, or is it related to ButteredToast that when booting into Recovery and fixing permissions, sometimes the ROM will continue to bootloop? HINT: Never touch a running system and ALWAYS make a BACKUP before changing anything important!

Can someone send me the link to Anryls kernel, please?
[HTC EVO 3D] bigwillyg:
I have yet to run into that. Did you make any other change?
[HTC EVO 3D] SecUpwN:
Thanks for your quick support. I have PDroid 2.0 on my device as well, not sure whether it's about wrong permissions or caused by ButteredToast. Also I noticed that Trebuchet (the default CM 10 Launcher) conflicts with GO Launcher Ex - I uninstalled Trebuchet, but when repairing permissions via 4EXT, is it possible that some files are given wrong permissions? Really strange thing, cannot even get a logcat of this behaviour as it is spoeadic. Back to default Vanilla kernel now until I know more about what's causing this issue...
[HTC EVO 3D] jcsy:
I'm not sure but yeah, just got a reboot out of a sudden

Data drops are minimal, but still present.

I flashed your kernel exactly 12 hours ago, and 12 hours from this post

No root problems

Just reboot, and data drops.

I used to fix permission in 4ext recovery with this kernel & Yoda's rom. No issue here. Fixing permission takes long time to finish, 10-15 minutes for me. Just make sure the process finish completely before you pull out the battery maybe. I assume you still can enter your recovery, flash your nandroid backup or other new rom.
[HTC EVO 3D] SecUpwN:
Pending for a kernel to stick with for a longer time. From their current development and support states, which one would you chose: ButteredToasT, Anryl or Yoda?

@bigwillyg: Would you please always place the MD5-sum for the current release of your great kernel into the OP? That way I know I grabbed it correctly. Thanks!
[HTC EVO 3D] timbohobbs:
Probably the wrong place to be asking. You should try them all like most of us and decide yourself. If not, start a thread elsewhere and take a poll
[HTC EVO 3D] jcsy:
you could start a thread, like mine for ICS for 3 kernels :D

if you havent seen it, then i guess you came after gingerbread :)

the thread is in my signature.. I havent found the time 2 do it for ICS

and also, i havent found a ROM i've completely been confident about in terms of everything working like how it was on Gingerbread, hence I've also not started

Billy, have you looked at my logs for reboot/data drops in Oppa Gangnam CM10 ROM?

http://db.tt/Z9HmNGsc
[HTC EVO 3D] Conny:
For those with high backlight level:

Use app from market

Backlightfilter

It works great
[HTC EVO 3D] SecUpwN:
Screw that, another reboot! What's causing them? I noticed that they obviously occur when having used my data connection before calling someone. Could you please have a look at the LOG and tell me whether it is an issue in PDroid, the ROM itself or ButteredToasT?
[HTC EVO 3D] helicopter88:
The best bet would be providing dmesg and logcat
[HTC EVO 3D] SecUpwN:
How to CONTINOUSLY collect those? Which app can constantly collect the relevant information each day (without slowing down the system too much) - so that if any problems occur I could pull that relevant file? Recommendations? What does my logfile reveal to you?
[HTC EVO 3D] helicopter88:
logcat and dmesg run constantly,you could make 2 init.d scripts that run

logcat > /sdcard/logcat.log

and the other one

cat /proc/kmsg > /sdcard/dmesg.log

Both logs would tell everything..
[HTC EVO 3D] bigwillyg:
Based on what I have seen so far in that log. I would have to recommend that you show it to the Rom dev. There are a lot of java errors and permissions errors in there. Start by showing him the log and see what he says while I finish looking at it on my end.
[HTC EVO 3D] SecUpwN:
Could you create these for me, please?

Try a clean reinstall of your rom and maybe reflash radio if possible. dont use the gowidgets or gopowermaster, and send me a last_kmesg and logcat like that if it happens again.
