Hmmm. The version of OCed kernel I have installed is 1.4.1 (downloaded on 6/1/2012 from where I forget). I'm confused as to why these new ones are numbered 1.3.0.

UPDATE: Did a little searching and see that the 1.4.1 kernel I have may be from his thread on the HTC Sensation. Interesting that the Sensation kernel would work on my Rezound. Is that supposed to work?
[HTC Rezound] mpguzman04:
So the OP and recent posts, read together, have got me thoroughly confused. Is this a kernel that works on the latest OTA 4.03.605.2 on sense 3.6 with all custom roms?
[HTC Rezound] drkow19:
Yup.
[HTC Rezound] mpguzman04:
And are there any known issues with any of the over clock speeds?
[HTC Rezound] hungsolow:
1.8 runs cool on my phone. I don't recommend CPU control apps tho.
[HTC Rezound] mpguzman04:
Can this OC Kernel coexist with danutzz's TurboPropV4, linked here: http://xdaforums.com/showthread.php?t=1684997
[HTC Rezound] hungsolow:
I use the kernel with the TurboPropV4 mod and everything is solid
[HTC Rezound] Evilmonstertruck:
I was wondering if there was a way to make a stock speed kernel with only one core activated to get better battery life? I ask because I can't get any CPU program to stick at the stock speed. It keeps moving.

Thank you
[HTC Rezound] drkow19:
That's actually a great idea for a kernel. For people who don't use heavy multitasking. But my guess is that would have to wait until HTC releases the ICS kernel source. Be patient, this phone has untapped potential!!!
[HTC Rezound] SebastianFM:
You can disable second CPU core manually in both, stock and my overclocked kernel. Run these commands from Terminal Emulator:

su

stop mpdecision

echo 0 > /sys/devices/system/cpu/cpu1/online
[HTC Rezound] apophis9283:
Will this shut off the second core permanently or just stop it being on all the time?
[HTC Rezound] Newt:
Just so you know man source code is up on HTC.dev have fun... If you already knew my bad lol
[HTC Rezound] SebastianFM:
So you can expect soon new kernel based on HTC source code with modifications such as in my Overclocked kernel for HTC Sensation.
[HTC Rezound] riot1031:
Is it possible that flashing this kernel would make my camera stop working? I'm running ConRom V6, I flashed this kernel plus TurboProp V4 at the same time, and now I don't have any preview when using the camera. The camera still works, but the screen does not show anything in the viewfinder when the camera app is open. I can still see the settings toolbar, and the buttons for gallery and effects, but everything else is black.
[HTC Rezound] JeramyEggs:
Hey Sebastian, I have followed along lurking quietly, and judging from your sensation kernel, you have all of the USB goodies. Would it be possible to launch Linux from my phone, and use a USB keyboard, and mouse? That would be pretty awesome. Also, would it break mhl in the process, or would that fall more into the room we are running? Thanks for all the work you have done here......:):):):):)
[HTC Rezound] Outta:
overclocked GPU? :D
[HTC Rezound] R187J:
Video Fix OC kernel any time soon???

Just wondering cuz I love the overclock just dislike having no internet video. :(

But either way It's a damn good kernel
[HTC Rezound] bik2101:
I think I might be having the same problem! are you on the latest v1.3.0 kernel too?
[HTC Rezound] riot1031:
Yes I am. I dirty flashed ConROM V6, and now my camera works again. It must be something in the kernel doesn't agree with something in this ROM.
[HTC Rezound] bik2101:
seems to be the case. damnit! i love the standby battery life with v1.3.......................

---------- Post added at 11:14 PM ---------- Previous post was at 10:46 PM ----------

just a heads up @riot1031 - the v1.2 works fine with the camera.
[HTC Rezound] riot1031:
I might go back and try 1.2 then. Thanks!
[HTC Rezound] riot1031:
Seems 1.2 works fine on ConROM V6, 1.3 causes the camera preview to not work. I went back and forth between the two last night, and it was definitely the kernel.
[HTC Rezound] chupajr:
Dude, you are the MAN.:good::good: I gotta give you some mad props for doing all this for us when you don't even own a Rezound!!! :highfive:
[HTC Rezound] bik2101:
yup. i can confirm this fact too. i'm on adrenaline 2.0 btw
[HTC Rezound] riot1031:
I can't wait for this!!
[HTC Rezound] SebastianFM:
There is no possibility to connect OTG and MHL at the same time, but you can use Bluetooth mouse and keyboard.

This is HTC kernel designed to work with HTC Sense based ROMs, not AOSP.

Sense 4? Install vinylfreak89's kernel with included ramdisk and video firmware especially for Sense 4 based ROMs, then flash my kernel.
[HTC Rezound] Nic2112:
ConROM is Sense based, not AOSP
[HTC Rezound] bik2101:
Sebastian - you had no problems with the 1.3 kernel affecting camera? Can I ask what rom you're running
[HTC Rezound] SebastianFM:
But I don't have HTC Rezound.
[HTC Rezound] bik2101:
ohhhh.. haha my mistake.
[HTC Rezound] famouscollin:
I'm curious as well is it reversible? If so can you give us those commands as well? And will this work on sense 4 rom? I'm really wanting to see that battery life increase two hours strait on my phone will kill it..

Edit: I have vinyls kernel installed so I'm assumin it will work on my rom.

[HTC Rezound] hgoldner:
So since SebastianFM doesn't have a Rezound; I'm wondering whether anyone else already running the Global firmware with a Global ROM (4.03.605.2) is now running version 1.4 of this kernel.

I know 1.3 runs without a problem on Ineffabilis Deus 1.2, which is based upon the Global leak (because that's my current kernel).
[HTC Rezound] hungsolow:
Sense 4? New governors?
[HTC Rezound] siulmagic:
This kernel support's, any rom, (sense based) because it flashes the raw zimage, it does not replace the ramdisk, so it is compatable with both sense4 and sense3.6. btw can any one nandroid this kernel and upload boot image, cwm6 for some reason wont flash this =/
[HTC Rezound] Po1soNNN:
Turn off signature verification or get a new recovery. cwm has too many problems on our device...
[HTC Rezound] :
I tried but YouTube wouldn't play videos :(, looking forward to trying this kernel by ruuing back to official ota. But we'll see!
[HTC Rezound] siulmagic:
its not that, somehow cmw6 wont let you flash anything, if you have bad zip on your sdcard, its minor nousense but its tolerable.
[HTC Rezound] Deathbyfugu:
So would someone on a 4.03.605.2 based ROM please confirm that this kernel is fully compatible (i.e. boots, camera/camcorder works, etc)? Thanks in advance.
[HTC Rezound] :
My review a few posts ago was for vigor1.1 which is global

After attempting to flash back to the boot.img for Joelz ROM I'm having issues booting. I'm gonna stay away from this kernel for a bit.
[HTC Rezound] mjh68:
Are you running it using a controller or just with the kernel ? I just got a measly 6100, I had 6400 running stock Nils ICS 1.3 kernel..wonder what the difference is ?
[HTC Rezound] Marcismo55:
I haven't. Have you tried toggling Airplane mode maybe?

I wonder if it has anything to do with the modules that were flashed in recovery for this kernel. Maybe restore a backup prior to flashing the kernel and flashing the boot.img form Joelz rom would work.

You're not alone..I only scored 6500 on Joelz's rom. I believe you are suppose to run Antutu on performance governor and after a fresh reboot.
[HTC Rezound] mjh68:
Hmm, Guess I can try the reboot. I did rerun it on performance governor , but did worse only 6069 lol .. I notice with system tuner it shows my second core offline not sure if that has anything to do with it or why it shows offline.
[HTC Rezound] rockingondrums:
In the first couple posts, people said this kernel is only for sense based ROMs, but it's my understanding that all the ROMs currently available (whether with or without Sense) are all based on the same leaked RUU. So if it's all an HTC base, couldn't this kernel work on a de-sensed ROM as well? Kernel source is not available, so most kernels out are essentially the same, right?
[HTC Rezound] WizeGuyDezignz:
After further review, what is everyone's opinion on real world performance and not benchmarks?

I was running Joel's ROM and installed this ROM. Initially my benchmarks were better than before installing it. After using the phone however under normal situations, it seemed more laggy. Mostly in scrolling and stuff. Maybe it's just me, but that's what I'm noticing.
[HTC Rezound] mjh68:
I give up.. after rebooting , performance governor using system tuner.. i got a 5040 ..rofl.. if I keep it up I might score below my droid 1 :eek:
[HTC Rezound] icy1899:
I'm running Joelz ICS original version desense with this kernel. I havent noticed a drastic preformace increase (using CPU Master pro) I also got lower Antutu scores as compared to the stock kernel
[HTC Rezound] icy1899:
Sebastian,

Would it be possible to enable States File for this kernel, using Antutu CPU Master pro on Joelz Original ICS Rom de-sensed, my phone seems to scale to 1134 MHz all the time, I want to see if this is accurate or if the widget is just not reporting correctly.

Thanks and keep up the great work
[HTC Rezound] k2trill:
If the phone works great, runs cooler, has the OPTION to OC, UC etc. and phone/battery up time is even marginally better than STOCK, then WHY THE FUSS ABOUT EFFIN "scores" which are very relative anyway?! No two people have the same apps and processes present and running anyway. What difference do they make?! Ooh yea somethin to tell ur friends about that guess what, DON'T CARE EITHER! smh. Please, for the rest of us, report relative bugs not thread obtrusive scores...
[HTC Rezound] Deathbyfugu:
I agree about the scores but was my device the only one that doesn't have both cores active?
[HTC Rezound] Njenson:
airplane mode... Reboots... reinstall... Still the same problems

Sent from my ADR6425LVW
[HTC Rezound] mjh68:
No, mine doesn't either. Shows 1 core off-line constantly.

---------- Post added at 02:17 PM ---------- Previous post was at 02:13 PM ----------

I understand that about the scores. My point with checking the benchmark was to see if one of my cores was truly offline or just not showing correctly. I figured if I scored at least similar to the stock kernel it might not be showing up correctly. With my scores being lower than my Droid 1 , and significantly less than the stock kernel I am surmizing either the kernel isn't working correctly on my phone or rom.
[HTC Rezound] Deathbyfugu:
+1 those were my exact thoughts.
[HTC Rezound] drynyks:
De-sensed roms are still sense when it comes to which kernels to use. It isn't sense vs de-sensed it is aosp vs sense. We don't have aosp roms yet that I know of. Then there is GB and ICS of course also.
[HTC Rezound] miatamx:
Jowels rom

If you check the software version of Joelz kerenel in about phone. This is the kernel he is using unless i am looking at something wrong.:eek:
[HTC Rezound] Argent36:
Well I haven't flashed this yet - but when I look under About Phone the kernel does list it as 3.0.13-gaf15497-dirty but when I go in to CPU master it doesn't go any faster than 1512 MHz - so I'm guessing Joelz is based upon this but without the OC stuff

*going to flash this now and will report back*

bah crapola - it won't flash - I get Main Version is older! Update Fail!

EDIT: ok fixed my mainvar problem - reflashed this kernel and now I can OC to 1.7 :)
[HTC Rezound] brando56894:

How the hell are you achieving those scores? I have mine maxed out and on the performance gov and 6368 in antutu!

[HTC Rezound] bkhorn:
I went back a couple of pages and couldn't find your post. Were you using 1.3 or 1.4 when you tested it on Vigor360 v1.1?

Thanks,

I was on v 1.4 which is the kernel based on the official ota (.12)
[HTC Rezound] hungsolow:
how bout sharin that CWM6?! :D
[HTC Rezound] drkow19:
Great work Sebastian :good: This kernel is awesome! I'm getting very consistent behavior, consistently fast. This works with Sense 4 roms, except video recording.
[HTC Rezound] SebastianFM:
Video recording isn't a kernel issue. It just requires suitable firmware and ROM. vinylfreak89 posted stock HTC kernel adapted for Sense 4. He included in his package original, unmodified stock kernel, Sense 4 ramdisk and firmware /system/etc/vidc_1080p.fw. Could you check this?
[HTC Rezound] Snuzzo:
No issues here on on SlimROM 1.8 + a modded version of yours (no perflock) I compiled for my own personal use. Everything works fine.
[HTC Rezound] ssb13:
When you installed Ineff 1.2 did you install the HD camera mod?
[HTC Rezound] drkow19:
I did flash his kernel first, but I have never flashed the firmware he posted along with it. Is that why? What are you asking me, I don't understand?
[HTC Rezound] yojoe600:
can you add fast charge to this?
[HTC Rezound] riot1031:
Thanks SebastianFM, this works great on my Rezound running ConROM now!!

One question, is it possible to overclock the cpu, but also undervoltage it to save power? (Kinda noobish question, but I just recently started flashing kernels, usually just stuck with whatever was included in the ROM). I have System Tuner installed, and pushed the CPU up to 1782, just wondering what (if any) values I could try for undervolting. Thanks!
[HTC Rezound] abby_nitewolf:
This does not seem to flash on mine. It gives me code 7 and tells me temp folder does not exist. I'm running ota ics
[HTC Rezound] wrarvoz:
Same thing here. Using twrp it gives an error when trying to flash.
[HTC Rezound] abby_nitewolf:

[HTC Rezound] SebastianFM:
In my kernel only boot-time perflock is enabled to decrease boot time so I don't see any reason to disable it. Am I wrong?

You must flash unsecured boot image first. For compatibility with Sense 3.6 and Sense 4.0 based ROMs my kernel package doesn't contain whole boot image, it uses existing boot image to create new one with replaced kernel.

After reboot default values are restored.
[HTC Rezound] Snuzzo:
You are quite correct. It wasn't a complaint, i LOVE your work and everything you have done up to this point. I like to set to conservative governor and the kernel was still kicking in perflock causing constant high frequency pinging.
[HTC Rezound] scy1192:
Flashed over a perflock disabled sense 4 kernel, seems to be working well. Wasn't stable at 1.8Ghz though, seems fine at 1.7. I want to try USB OTG, but your thread pertains specifically to the Sensation. Anyone have experience with it on the Rez?
[HTC Rezound] Snuzzo:
From my understanding the rom has to have the option enabled in it as well. I foresee it mainly going to be an AOSP thing.

@SebastianFM

Speaking of AOSP, would this also work on CM9 if I flash over the top of Chad's?! Hmmm....

More testing to do.
[HTC Rezound] hungsolow:

[HTC Rezound] wrarvoz:
How do you do this? Where do I find this unsecured boot image that I must flash first. I feel like I missed something, as there is no reference to this in your first post. I'm s-off btw.

[HTC Rezound] SebastianFM:
Why do you think that is perflock related? Could you tell me more about this?

My thread about USB OTG isn't only for HTC Sensation anymore. Sensation and Rezound boards are quite similiar and kernel source code related to it also. I made identical changes in both kernels to enable USB OTG. I'm sure that it will work but someone should check it out. Do you want to be first? :)

I tested my kernel for HTC Sensation with CM9 for HTC Sensation and I found only one issue, SD card mount.

[HTC Rezound] Snuzzo:
Well technically it isn't, there are other means to set governor which be used. Quick easy way is with a cpu control app, which cause the high pinging due to the frequency monitoring in the app(s). Trust me, if it looks like I am trying to come off bad towards you, I'm not. Just trying to help :)
[HTC Rezound] hungsolow:
perflock causes the pinging not the monitoring app...

[HTC Rezound] hungsolow:
Is perflock completely removed in the next update?
[HTC Rezound] SebastianFM:
I still don't see any reason to disable it.
[HTC Rezound] hungsolow:
That's funny because in 99% of the Rezound threads/discussions this is like one of the top 3 reasons (if not THE main reason) everyone in the Rezound forum was waiting on source from HTC. I don't think ANYONE here prefers perflock and having there phone chew through batteries because the processors are pinging the kernels maximum frequency every few seconds regardless of what you have the minimum and maximum frequencies set at. you may want to take a vote, but I think I speak for the masses when I kindly request that you disable perflock...
[HTC Rezound] Snuzzo:
Speaking of which, how did that rom perform for you?
[HTC Rezound] hungsolow:
I messaged you back. it ran cool (temp) for me. I used it for about 4 hours last night :)
[HTC Rezound] Snuzzo:
Told yah its the monitoring app and not the kernel itself. :)

PS never got the reply :/
[HTC Rezound] SebastianFM:
Unfortunatelly I can't test this myself. But it's weird for me. Kernel which I prepared for HTC Sensation has almost identical code and configuration. I haven't any issues. Are you sure about symptoms? Did you try to manually read frequency stats instead of using monitoring app which could cause frequency increase? I looked through whole kernel source code related to perflock and I didn't find anything which could cause this.
[HTC Rezound] hungsolow:
I posted 2 separate videos of my phones.... one is running your kernel and the other running dsb's kernel. you can clearly see that the min. WON'T STICK because of perflock. I've now tried even Joelz kernel (no peflock) and it doesn't ping the high frequency either. I think this is the sole reason all other kernels/kernel devs have removed perflock.

I wouldn't even be mentioning this if this>> "Fixed ACPU and perflock to allow setting different maximum CPU frequency than highest available." weren't in the OP's update/changelog for V1.4. I know 1.4 was released post HTC source release. Perhaps you should clarify what the above means because I took it ti mean perflock removed like everyone else's.
[HTC Rezound] SebastianFM:
I think you don't know what is perflock!

When perflock is enabled CPU frequency is locked on defined frequency (e. g. boot-time perflock) or between defined minimum and maximum frequency (e. g. screen off perflock). That's all. Boot-time perflock locks CPU frequency for 60 seconds to decrease boot time.

I fixed perflock. Look at my changes in source code. When I added highest frequencies to CPU frequency table, kernel booted at 1836 MHz and also perflock locked CPU frequency at 1836 MHz. After small changes in code kernel boots at 1512 MHz and also boot-time perflock locks CPU frequency at 1512 MHz.

Original source code:

arch/arm/mach-msm/acpuclock-8x60.c

for_each_online_cpu(cpu)
max_cpu_khz = select_freq_plan();
...
acpuclk_8x60_set_rate(cpu, max_cpu_khz, SETRATE_INIT);

arch/arm/mach-msm/perflock.c

BUG_ON(cpufreq_frequency_table_cpuinfo(&policy, table));
policy_min = policy.cpuinfo.min_freq;
policy_max = policy.cpuinfo.max_freq;

Modified source code:

for_each_online_cpu(cpu)
acpuclk_8x60_set_rate(cpu, 1512000, SETRATE_INIT);

arch/arm/mach-msm/perflock.c

BUG_ON(cpufreq_frequency_table_cpuinfo(&policy, table));
policy_min = policy.cpuinfo.min_freq;
policy_max = 1512000;
[HTC Rezound] a.mcdear:
No there is definitely something weird with the frequency scaling in this kernel.

For example, I will set it at 192/1782, but then every time the screen turns off and I unlock the phone its at 1512/1512, then immediately resets to 384/1512 and completely ignores my custom setting of 192/1782. If I use something like Profiles in SetCPU and use the widget for monitoring the frequency, I can see that it is still clearly switching itself to 1512/1512 every minute or so for a few seconds, then goes right back to the active profile speed of 192/1782.
[HTC Rezound] SebastianFM:
It's just because something weird is with SetCPU.
[HTC Rezound] a.mcdear:
Even when I remove all settings from setCPU and use only the widget solely as a means for viewing the current frequency but not setting it, I still see weird behavior. When I set the CPU speeds to 192/1782 via Terminal, it still goes back to 384/1512 after turning the screen off once and turning it back on. Even if the screen doesn't go off, it still eventually resets itself to 384/1512 on its own.
[HTC Rezound] hungsolow:
No, there's nothing wrong with SetCPU. I'm using System Tuner Pro anyway as I illustrated in the videos I posted a couple pages back. YOUR kernel is the only one exhibiting this behavior. I really don't see the big deal with leaving "boot time perflock" on because it doesn't bout any faster than anything else anyway. We appreciate your work but leaving perflock in place (however u wanna dress it up) is not helpful. Again, if you bothered to look at the videos I posted you would SEE Wut's goin on. There's no need in my reading all that technical mumbo jumbo because I don't understand it or I'd b building my own kernel. All I can do right now and until I learn more, is report my findings....
