Slightly sluggish with delay after install...

Hi!

It's now about a week ago since i flashed 1.512 GHz OC kernel 3.0.16-g5e58c5e v1.01 for HTC Sensation onto my stock 3.24 and after a couple of days of using it my device has become a bit sluggish or kinda of delayed when i unlock it and want to use it quickly...

So i feel i must ask, must i or should one do a full wipe after a kernal flash?

I did not make a factory restore just wiped dalvik as 4ext suggested at the flash.

My device was VERY fast and responsive at first but after a couple of day not.

I don't know if this is the kernal or them test ROM. :)
[HTC Sensation] Jonny:
Check your governor and power-save settings and if necassary change govenor or uncheck some of the settings
[HTC Sensation] ToddeSwe:
Hi, thanks. Now I'm not that good at this, do you have any suggestions for me? I'm on-demand at the moment, using system tuner to check this. What app do you use to change behaviour?
[HTC Sensation] Jonny:
system tuner pro > boot settings > screen off (something like that)
[HTC Sensation] ToddeSwe:
What values do you use?
[HTC Sensation] ziggy1001:
If it's sluggish after screenoff for awhile then increase screenoff min CPU to 384 some don't like 192
[HTC Sensation] everyday48:
great.thank you.
[HTC Sensation] ToddeSwe:
Thanks that made a big difference :) So 192 is the default value? Im asking because mine was not showing any value used in system tuner.

[HTC Sensation] SebastianFM:
Thanks very much, I'm drinking just now. ;)

The first CPU frequency value should be lower than max frequency.
[HTC Sensation] erto90:
Sebastian have you looked at possibility to use camera's flash at every battery percentage?

Highlighted value should be less than max right?
[HTC Sensation] mat9v:
In a way, yes as it allows CPU to reach higher temp before the frequency is lowered so the result is longer operation @ higher frequency. The cost is higher temp (not nice for your hand) and lowered (hard to quantify) lifespan for your hardware. Here is my thermald.conf (with modified last line as I use 1.7Ghz kernel)

The last line is dependent on what kernel are u using, if overclocked one you can try something like: 1512000 1134000 756000 432000 (for 1.7Ghz)

Sampling values are too high - the heat does not increase so fast (er... I hope thos are not values per second...hehe)
[HTC Sensation] d3vilskid:
He is working on an oc/uv kernel right now that's default at 1.5 overclockable to 1.836
[HTC Sensation] Jonny:

Then for disassembling and editing the zimage, try IDA (Interactive Dissassembler)

[HTC Sensation] amm009uk:
+1 zero issues quite boring:-)
[HTC Sensation] broncogr:
Thread cleaned.

Watch you attitude and stay on topic
[HTC Sensation] PaulGiz:
Just to reiterate:

4.0.3/Sense 3.5/Base 3.12: 1.5 and 1.7 kernels available and working -- specific to your base.

4.0.3/Sense 3.5/Base 3.24: 1.5 (UV) and 1.7 (with or without UV) available and working -- specific to your base.

4.0.3/Sense 3.6/Base 3.25: 1.5 (with or without UV) available and working-- specific to your base. In addition 1.7Ghz kernels for Base 3.24 (with or without UV) are known to work with your base.

Disclaimer: All chipsets are different. Your specific phone may or may not work with any kernel. Always back up a known working setup before experimenting. Always clear cache and dalvik when flashing a kernel.

An incompatible kernel will not break your phone. Some functions may not work (WiFi comes to mind). Mostly you can get instability -- random shutdowns or reboots.

Thanks to Sebastian for his work.

hey sebastian...thank you very much for your work - it's just awesome!

i have a question...from my time with the desire - a developer has made some audiomods in the kerne (http://xdaforums.com/showthread.php?t=801435) is there any chance that this could be also done with this kernel...??
[HTC Sensation] biggunsv:
In case someone interested, just tested 1.5 GHz OC/UV kernel on TripNMiUI v4 B004 - works perfect. This means it should also work on his AOSP and CM9 ROMs, because they all use stock HTC 3.0 kernel.
[HTC Sensation] :
I'm running 1.73 OC kernel on Quattro a3 with no issues. Using system tuner to force CPU online and clock both from 384-1728 on demand does not seem to produce any issues.
[HTC Sensation] q9650:
Actually it is...show-p did it on his gingerbread kernelz afaik :)
[HTC Sensation] matrix_skopje:
how can i know which kernel is the right one for my HTC Sensation XE running Eleganca 2.20 custom rom???

thx in advance
[HTC Sensation] peterjayrolle:
I just flashed the sebastion 1.5ghz kernel to my Sensation and ran the bench test and the speed still says 1.18. How do you guys get it to 1.5 in the bench test??
[HTC Sensation] SebastianFM:
The temperature value is correct, it is always multiplied by 10. I don't know why your phone reboots, maybe 1.728 GHz is too high for your CPU. Have you tried to reduce the max CPU frequency?

I don't know how to increase audio volume in HTC Sensation, audio related kernel source code is different and doesn't contain min and max gain values.

Actually I know this and I wrote about it few pages before. Low battery limit value is really stored inside the kernel, but system or camera app turns off flash when battery is too low. I'll try to decrease this limit in the next release.
[HTC Sensation] ansonchan:
hi sebastion,can i ask is overclocking will harm our hardware?
[HTC Sensation] tangcla:
It's not going to extend the life of your phone, that's for sure. But generally yes, overclocking is going to shorten the lifespan.
[HTC Sensation] JustANotherMe:
any chances to include the new bluez ?
[HTC Sensation] SebastianFM:
Without kernel source code available - no.
[HTC Sensation] ansonchan:
so just for example like sensation and sensation xe have the exactly same hardware but sensation xe is with 1.5ghz by default,isn't it also just overclock by htc with the same hardware with sensation?

[HTC Sensation] Tigermoto:
As long as you have a backup bro, try one. I'm using this one from the first post with no trouble whatsoever on my XE with CoreDroid V4.

With all due respect, remember you are asking for support on a development thread and that's not really what they are for, so if a question doesn't get answered, don't repeat it, 99% of the time someone will troll you out for that in a dev thread.

But......i agree, politeness costs nothing.

Have you asked the Developer of your ROM Steve0007 what he suggests?

I'm not being militant bro, i may get called out for this too.

I would say, as long as you have a working backup, trial and error is good, find one you like. :)

Hope this clears up a few things

Not having the issue anymore. Hope this helps other having the same issue
[HTC Sensation] Dai323:
Im also hearing the 1.7 kernels work fine too. Exactly which 1.5 kernel are you using, as there are more than one?

Also, can we force the other core online with this kernel, or should we leave it off?
[HTC Sensation] mat9v:
@Sebastian: I may have missed something, but in OP you have a screen with 1782Mhz kernel. Where can I download it? Is it ready for a "public consumption"?
[HTC Sensation] beston94:
So these kernels will.make my Ics faster and smoother?
[HTC Sensation] mat9v:
Yes, but @ the cost of bigger battery drain and higher temp. And your CPU `may`not be stable with higher frequency and crash the phone. As they say, results may vary.
[HTC Sensation] Tigermoto:
YMMV of Course mate, but has with mine.

On a separate note, Hi Beston, thought you had got away from me eh?

In the OP my brother, or click Here

This is a direct link to the download of the 1782 OC and UV kernel from the OP

Hope this helps...
[HTC Sensation] beston94:
Thanks a lot! And do I remember you from the coredroid htc hd2 forums? hehe long time I haven't checked ;D

PS: Can I flash these kernels on the virtuous inquisition v3.0.0?
[HTC Sensation] mat9v:
Well, it would if the link and OP did not have the 1728 and not 1782 kernel. See screenshots in OP. Either the files (and links) are named incorrectly or the 1782 kernel is not posted.
[HTC Sensation] wmoore:
Took me a minute to figure this one out :D

Typo - 1.728GHz is correct, 1.782GHz doesn't exist.
[HTC Sensation] Bluewall:
Hey guys !

Correct me if i'm wrong, i'm going to flash the 1.5Ghz UV kernel. Then i underclock it to 1.18Ghz with SetCPU so no bigger battery drain but better battery life since it's UV no ?

Btw, how much mV is it UV?
[HTC Sensation] bobbytomorow:
I'm running Trips CM9 B007, and want to run a 1.512GHz Kernel but what one of these would work best with that ROM?

I'm currently using this kernel:

1.512 GHz OC/UV kernel 3.0.16-g5e58c5e v1.01 for HTC Sensation

It has the phone running a lil warm and has rebooted a few times while benchmarking
[HTC Sensation] mat9v:
Come on men, look @ the OP pictures, the third one has 1782 kernel and if you look @ the scores there is about 3% difference - close to the difference in frequency.
[HTC Sensation] Technane:
does this kernal have the change needed to allow the camera flash to be used lower than 30%?
[HTC Sensation] SebastianFM:
My phone isn't stable at 1.782 GHz. I succesfully finished Antutu Benchmark only few times. I'll include frequencies above 1.728 Ghz in next release, but probably they won't work stable on most phones.

No, I'm waiting for the new HTC kernel to add this fix and other changes.
[HTC Sensation] PaulGiz:
I was very surprised that my phone runs very well @1.728, I had issues at high clocks on GB ROMs. Thanks for continuing with 1.7 for those of us that can run them.
[HTC Sensation] Tigermoto:
I'm quite lucky, my XE has been clocked previously to 1912MHz with a different kernel, but i love the way your kernel runs so smoothly.

Great work SebastianFM
[HTC Sensation] mat9v:
Same here, my phone works quite happily with clock 1.92Ghz @1.3V (but I have to lower max frequency for second core to 1.8Ghz). It's easy to do with a simple script, the only thing to hope for is GPU overclock :)

The idea is the 2nd CPU is only used when needed so obviously a lot of the time it's idle
[HTC Sensation] mat9v:
There is a system binary "mpdecision" that should decide when it is "time" to turn second core online. It mostly works ok, but sometimes the second core is not turned on so some people force it online (in system tuner for example). It costs in power usage so you have to decide.

I have a question about this kernels. I've been trying to install the 3.25 compatible kernel to my sensation running hypernonsense v0.3 and both get me to a bootloop. This is not the first time I flash something on a cellular. I've been doing it since the days of windows mobile, I'm no expert but I do follow directions really good and I see no reasoning for this. The only thing that gets me out of the boot loop is restoring the kernel to stock. Anyone can give me pointers as to what the problem might be. Before flashing the kernel as always recommended I wipe /cache and wipe dalvik cache, is there something else that needs to be done with sebastianfm's kernel?

Note: My recovery is cwm touch recovery. Not sure if this would have anything to do with it.

I also tried the kernels for 3.24 and no luck even when I was on ExtremeSensation Blitz. The only one that boots is the 3.24 compatible 1.72 oc/uv but that one causes crashes and reboots....please help!!!!
[HTC Sensation] mat9v:
What ROM version are U using now and with what firmware (the one for 3.24 right?). Which exactly kernels are U trying (links?). Crashes and reboots are generally caused by too much overclocking / undervolting. You could try the corresponding (for the same base) kernel but without UV (undervolting).
[HTC Sensation] RayHeath:
Sebastian, just want to let you know that the kernel 3.0.16-g9788208 does work great on the 3.25.401.101 based rom with CoreDroid just fine. I´m running it OC´d @ 1.728 GHz on my XE with CoreDroid XE V4.1 Sense3.6 RC3, and it´s running beautifully. Actually this is the best that my battery´s been. Thanks! :)

Actually I´d be curious if you could do one @ 1.9 GHz... I´m sure that it would work with my XE, but probably not on the standard Sensation.

[HTC Sensation] SebastianFM:
I launched AnTuTu Benchmark a lot of times on my HTC Sensation and sometimes I had poor CPU scores, even on the stock kernel.

Finally I found a bug in HTC ROM. The mpdecision daemon doesn't work properly. This daemon decides if enable or disable CPU core 1. Also it enables both cores and sets maximum CPU frequency when recognizes that AnTuTu Benchmark process is running. I checked that the proper voltage isn't set to the CPU and memory in this situation.

In the AnTuTu Benchmark's changelog there are informations that "fixed low scores of CPU benchmark" and "fixed a bug that may be cause unreliable CPU score in some device" but I'm sure that the real reason for low scores is the bug in mpdecision.

If you have sometimes low scores in AnTuTu Benchmark, try to use these command before running benchmark:

adb shell stop mpdecision
adb shell "echo 1 > /sys/devices/system/cpu/cpu1/online"
adb shell "echo 1512000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq"
adb shell "echo 1512000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq"
adb shell "echo 1512000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq"
adb shell "echo 1512000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_min_freq"

When the benchmark is running you can check the current CPU frequency:

adb shell cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
adb shell cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_cur_freq

To restore default settings you can reboot phone or use these commands:

adb shell "echo 1512000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq"
adb shell "echo 384000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq"
adb shell "echo 1512000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq"
adb shell "echo 384000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_min_freq"
adb shell "echo 0 > /sys/devices/system/cpu/cpu1/online"
adb shell start mpdecision

Also if the mpdecision daemon works incorrectly, it could cause lowered performance or stability issues when running other applications.
[HTC Sensation] leeznon:
If I overclock to 1.5 from 1.0 how much worse will my battery be? Do these kernels make your battery last less?
[HTC Sensation] Jonny:
You can always use the UV kernel then use system tuner pro to change the max value back to 1.0 and still have under volt so your battery will last longer ;)
[HTC Sensation] ianoob:
will these changes be included on the next update?
[HTC Sensation] magic_man:
There is nothing to really change in the kernel. The mpdecision program just turns on cpu1. FM is just turning it off and manually setting the frequencies.
[HTC Sensation] ianoob:
Didn't know if he could edit the mpdecision file
[HTC Sensation] mat9v:
Well, you can disable mpdecision completely. Just rename it, its in /system/bin folder. But then you have to force cpu1 to be online always because otherwise it will be permanently offline.

As to the performance in various benchmarks, I tried logging frequency changes with ondemand/interactive governors and I found that with default ondemand governor, cpu1 never stays @max frequency through the benchmarks - that is why benchmarks with "performance" governor yield better results. To force better performance out of ondemand governor you have to play with some values:

echo "40000" > /sys/devices/system/cpu/cpufreq/ondemand/sampling_rate
echo "2" > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor
echo "15" > /sys/devices/system/cpu/cpufreq/ondemand/down_differential
echo "60" > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo "45" > /sys/devices/system/cpu/cpufreq/ondemand/powersave_bias

(this is how I have them set up) but once set correctly, you can have almost "performance" governor performance with only slightly higher power usage.
