I tried 4a on Deck's ROM. Works smooth now, but is no faster than the stock kernel without the dual CPU. My SmartBench scores are usually around 2060 but this is what I don't understand. ONE time when I ran SmartBench, the multithreaded (multi-core) fractal test finished in less than 2 seconds: really fast. That time I got a 2770. Best I've ever gotten. Ran it again and the same multi-core test ran at least twice as long and the score dropped to 2060: about what I normally get.

It looks to me like dual core might be running but it is sporadic. Sometimes it runs/helps. But most of the time it doesn't. At least now (with 4a), I don't see the massive slowdown in graphics. Everything looks normal. I'm just not seeing any speed increase except for that one anomaly.

[HTC EVO 3D] jkcpsal:
Hey freeza loving the kernel, probably more so for the ciq removal but the dual cores is just icing since battery life doesn't seem to take a big hit. One thing that would be cool especially with the frequent updates would be if you could get them in kernel manager. Not sure if its been asked or what it takes but its slick.
[HTC EVO 3D] freeza:
Have been considering this, but since it is simply a modification of HTC's kernel, I'm not sure. BUT once they release kernel sources, all that may change. :)
[HTC EVO 3D] Rydah:
Should this work fine with the stock unmodified odexed ROM?
[HTC EVO 3D] freeza:
Yeah, it should work fine.
[HTC EVO 3D] laie1472:
Sup freeza?? Hope all is good man. A just flashed zip/update 4 and everything went cool. Running smooth and I notice a huge performance boost on app loadind,wifi connecting,sync,boot time,mobile dl and up, mms sent quicker,text msg definitely sent qiucker,scrolling is way smoother,transitions are buttery, overall man this kernel is off the chain. Thanks.

Wifi issue with 4a?

I just put the 4a kernel on and everything seems ok except that my wifi won't fully connect. It sits there are obtaining an IP address. Is this happening for anyone else?
[HTC EVO 3D] phatmanxxl:
Not me, it connected right away after boot.
[HTC EVO 3D] oldjackbob:
I put the 4A kernel through its paces this afternoon and evening, recording a mountain bike ride on MyTracks while listening to tunes on Cloudskipper, and only burned through 12% battery over 1 hour 43 minutes' time. That equates to well over 14 hours battery life at that burn rate. What other phone can boast of that kind of battery life while recording a GPS route and listening to tunes? :cool: And my cpu loading was apparently very low...the vast majority of cpu time was spent at 192 mhz (nearly 3/4 of the total time), according to the SetCPU Time in State pie chart, and nearly half of the remaining time was spent at only 384 mhz. So hardly any time at all was spent at 1134 and 1188 mhz. I've got SetCPU set at 95% up threshold, a Powersave bias of 32, a Sampling rate of 20000 microseconds, screen-on of 192/1188 ondemand, screen-off of 192/432 ondemand.

The powersave bias of 32 and the 95% up threshold means that I rarely actually visit the upper limits of the speed settings, so I hardly ever reach any clock speed over 384 mhz screen-off or 1134 screen-on. I've always had my phone set up with those SetCPU parameters, so I'm actually quite gentle on the clock, but the capacity is always there if really needed. And it's really impressively fast. Running a single-core kernel I can get a best of 2156 on Quadrant, and very smooth graphics on Smartbench. Running the 4a dual-core kernel my benchmark results are statistically identical to the single-core kernel...2126 on Quadrant, and again very smooth graphics on Smartbench.

Forgot to mention, I'm running SteelROM 2.02 (for some reason SteelRom 2.1 and 2.2 really bog down on the benchmarks, at least for me...I need to focus on trying to find out why over the weekend).

So to answer someone's question regarding what benefit the dual-core kernel offers, I'm still not sure, but it doesn't appear to exact any extra price in battery drain and my cpu is just loafing along under load so I'm a happy camper. :cool:
[HTC EVO 3D] Tiffany84:
Running 4a with Myn's warm 2.3 and so far it's running great. Thanks Freeza.

[HTC EVO 3D] Tiffany84:
It's not officially available yet. But the thread is on rootzwiki. U can use svn to build a nightly. It's running really good too.
[HTC EVO 3D] aalopez10:
Yea thanks just check he's Twitter n got my svn set up, now gonna try it out n test it with this kernel
[HTC EVO 3D] toneman1984:
Omfg this kernel paired with synergy running on performance mode is the fastest I've seen my 3VO. Strangely enough, my easiest benchmark is the developer page for the 3VO forums. On the og EVO this page always ran slow. Even on the 3VO this page was laggy. Even when scoring 3000+ on quadrant this page was laggy. After flashing this kernel It is no longer laggy. Thankyou op. You are awesome. I just scored 3000 with quadrant. I did the ext4 /data optimization on synergy which I think speeds things up too.
[HTC EVO 3D] mikeyxda:
You must be using one of the Synergy 2.3.3 ROM's with an OC kernel, right?

[HTC EVO 3D] twcrosno:
Has anyone had an issue using ROM Manager or Titanium backup after flashing any of these kernels? I flashed #3 yesterday and I couldn't backup anything with ROM Manager or restore. I installed Titanium and it stated I wasn't backed up. I was on CMYLXGO 8-29 when this happened, so I flashed back to SYNERGY and I was able to use ROM Manager. Sorry if someone posted this already.
[HTC EVO 3D] pstevep:
titanium works fine.. just made a back up to test.. i dont use rom manager so i cant test it.. but it shouldnt really affect it, and i havent heard anyone else complaining about it not allowing backups.. and with all the flashwhores around here, im fairly certain some would be making some..
[HTC EVO 3D] twcrosno:
Yeah, I look through the posts and I did not see anyone else with this issue. My 3Vo seems to have a mind of it's own at times. I'll chalk it up as a fluke. Thanks pstevep!!
[HTC EVO 3D] htownrep247:
Where is the link for svn on that rootzwiki page? I can't seem find where it is on there.
[HTC EVO 3D] malicon:
running 4a on XRON3VO RSL2 ODEX (with virtuous) since it was posted yesterday and performance and battery seem great so far. Watching a bit of CPU activity in system panel seems like frequency rarely gets to max speed.
[HTC EVO 3D] Product F(RED):
Is perflock disabled in this kernel since it's a modified stock kernel? Because I'm on ViperROM and his battery script won't work if perflock is present.

Hey Freeza do you mind if I use your kernal in my ROM Im trying to make? Purrrrty Pweeeeeeeeeeeeeeeeeeease!!:)
[HTC EVO 3D] nonpointtruth:
Freeza, would you recommend using this kernel with your SP1 update? I've noticed lots of lag, plus my benchmarks don't even scratch 2000.
[HTC EVO 3D] guitardoc64:
Update 4 didn't work for me. Slowed everything down and made my EVO act more like my Hero.

Sent from my s-off Shooter!
[HTC EVO 3D] freeza:
Of course, no permission necessary. Feel free. :)

SP1 includes the second kernel from the OP (with CIQ removal)

So yeah, any of the Dual Cores would work, but if it is giving negative results, the second one is fine.

Try 3a?
[HTC EVO 3D] guitardoc64:
Not yet. I'm using my own version of xhausx's rooted stock, (most bloatware removed)btw. I'll give that one a try. The update stock CIQ removed has so far worked best.

Sent from my s-off Shooter!
[HTC EVO 3D] guitardoc64:
Ok Freeza, update 3 works. I'll run it a while and let you know how it works over time. I'm so missing overclocking HTC needs to get off their asses and release the source.

Sent from my s-off Shooter!
[HTC EVO 3D] Joey121215:
Freeza, I'm having a bug with 4a, I switched back to stock for now, hoping for a fix. But anyway, ever since I installed this kernel, I'll randomly lose contact with sprint towers and texts will stop sending/receiving properly. I would be able to fix this by making a call. Once I flashed the stock kernel back I received a bunch of missed texts. I'm on stock odexed.
[HTC EVO 3D] d0cx:
I have 4a installed and, while it runs great, I don't see much of a difference.
[HTC EVO 3D] guitardoc64:
3a worked ok, but I noticed some lag. Back to the stock update CIQ removed.

[HTC EVO 3D] Riff76:
my phone kicks with 4a. Battery life good as long as there is a good signal. It will drain the battery pretty fast if you're in a service dead zone.
[HTC EVO 3D] fowenati:
Few things:

How does dropping the second cores speed implement dual core support? Is there another script that tells the OS to utilize both cores equally? I'm guessing that it doesn't and the dual core support is mainly just for battery life, rather than performance.

Also, is the kernel for 2.3.3 or 2.3.4 ?
[HTC EVO 3D] EVOme:
I have 4a running. Will see how it behaves over the next few days. Thanks!!
[HTC EVO 3D] b.huss2:
i've tried every option, and although dual core support sounds really cool, i can't see any real improvement on performance. the only thing i can see is a dramatic decrease in benchmarks, not just linpack and quadrant but every benchmark tool i've tried (and i tried a bunch). now i know benchmarks don't mean everything so don't flame on me but i gotta believe that it means something. imo the best kernel for 2.3.4 right now is the stock "update2 " without the dual core support. great performance and you don't have to avoid benchmarks like the plague.

Edit: i meant the update link, not update2. Before dual core support was implemented.
[HTC EVO 3D] toneman1984:
What are the differences in your quadrant scores between those two kernels?
[HTC EVO 3D] toneman1984:
Nope no overclocking on 2.3.4
[HTC EVO 3D] b.huss2:
With the first 2 zips, I get normal benchmarks. with quadrant its around 2000-2300. Any update with dual core support drops ALL benchmarks. Quadrant specifically goes down to around 1200-1400. Yea, I was shocked at the 1200!
[HTC EVO 3D] ianoob:
I tried 4a with Shogun odex, quadrant of ~2600 before and ~2200 after... Before system panel would show 1st core peg before 2nd kicked in, now running cooler and in tandem. Worth it to me.
[HTC EVO 3D] freeza:
Expect kernel updates across the board tonight. With new information from TrevE, I can finally remove htc ipc server from ramdisk without worrying about any ill effects. :)

I'm getting different results myself using the dual core kernels with the stock rom.

Stock kernel + stock rom I was getting ~1800 consistently, with the 100% dual core modded stock + stock rom I'm getting a bit above 2000 with no changes at all (literally right after flashing).

Decided to stick with the dual core in the end.

[HTC EVO 3D] freeza:
init.d support are initialization scripts support (on boot), no dual core support. The second core activates when it wants to. :P

Dual Core just activates the second core at all times.
[HTC EVO 3D] huytrang90:

[HTC EVO 3D] freeza:
It shouldn't degrade performance at all. But for people who love quadrant scores, it may decrease them just a tad. For some reason, the second core doesn't play nice with that app.

Hello everybody. Noob to Kernel flashing here, so I apologize if I'm asking anything thats incredibly unknowledgeable here. I'm curious as the portion I bolded above. What exactly is meant by that, or what does/should it mean to me?

And does this imply that stock kernels do not fully support dual core? I've read up on that subject and there's a lot of conflicting information out there about it.

Thanks for your patience ;)
[HTC EVO 3D] Coriolis3ffect:
Will this kernal work with Eternity 1.4.1 and will dual core eventually cause the processor to burn out completely?
[HTC EVO 3D] :
It's a ghetto attempt to make your phone synchronous. Yes, the stock kernel does support dual core, but the SoC is asynchronous, and these modified kernels try to make it synchronous, which it will never be, truly of course. Cayniarb already chimed in on this, and he stated that running these types of kernels is unhealthy for the SoC, which makes sense. IMO stay away from them.
[HTC EVO 3D] Scott:

I think if you were an early adopter you got a bad file. The one posted there know works for sure. I will mirror on my DB: http://dl.dropbox.com/u/31360541/Evo_3D/StockKernel2.08.651.2.zip

Let me know if it works for you Kaos.

Thats the one I just downloaded and it works! The first one was a diff file. I swear to this! Or I hosed something up but even if I did that I wouldn't have got as far in the boot processes as I did. Meaning, if I was flashing the wrong kernel then the phone should have soft bricked but it wasnt.

Does this post make any sense at all? :confused:
