Thanks!!

There a lots of people that only can use non undervolted kernels. Other developers dont mind sensitive voltage CPU users.

Thank-you for remind us!
[HD2 Android SD Development] Blades:
Oh you're killing me Hasta.. :) Is this disabled overclock a matter of Kconfig settings?

do we need to do anything with startup.txt, I thought I saw a note about changes in memory addressing.

another thing.. are the ipv6 related network settings/options/flags in Kconfig necessary?

edit: ok.. I got oc enabled. 1305mhz works at 1.4V.. heh :o no stir fried phone at that voltage.. yay
[HD2 Android SD Development] Blades:
are you sure about that? seems like lights.qsd8k.so is the name to choose.. unless, there is a reason for renaming it to the name above..
[HD2 Android SD Development] elitishtc:
what to say..

Just thanks for all good working over there

The only concern for me is battery . . . . i dont want to live this kernel but...
[HD2 Android SD Development] sxypapi:
so far so good. battery is good.good internet connection, no drops,smooth as butter, thanks for ur work,its always appreciated :D
[HD2 Android SD Development] Beefheart:
Terrible battery life on R8 for me in comparison to 7.7. Can't get standby below 60mh where as 7.7 was on average between 5 and 7mh.

Back to 7.7 for the time being.
[HD2 Android SD Development] hastarin:
That's a joke right? Because anyone that took a few minutes to read my FAQ wouldn't have that problem.

Sent from my HTC HD2
[HD2 Android SD Development] hastarin:
It's just a build option and since I know you can build your own kernel you're free to ignore my advice and overclock, etc

No change to startup.txt is necessary.

No idea they come from the default config.

Sent from my HTC HD2
[HD2 Android SD Development] Blades:
no disrespect hasta.. :) I just like it for the warmth. wifi mac assign works nicely. I'm going to see if the kernel slims down with ipv6 stuff removed.
[HD2 Android SD Development] asphaltkiller:
V8 kernel is great even for battery consumption getting between 4 and 8ma in sleep

Absolutely no lag no sod no data drops so far (tested on shubcraft 2.0 and andromeda 1.3)

I can confirm that axi undervolted kernels are useless!

I m just missing overclocking for some games like reckless racing

Thank you for hastarin you made good choices!
[HD2 Android SD Development] Beefheart:
No, it simply doesn't give me the battery life of 7.7 on my build of Bangsters 1.5. This is despite renaming the lights.so file to lights.qsd8k.so as dictated in the build.prop file and all other aspects of my build is the same as what I had running on 7.7. I have tried the other advice in the FAQ too.

By the way, this isn't a dig at your kernel which is the best out there in my view and I have been using it for some time. As I said, a terrible battery life for me which isn't indicating everyone is going to have the same issue. I say this as you seemed a bit defensive there which is perhaps understandable. Perhaps if I started again with a fresh Bangsters build the issue would go away.
[HD2 Android SD Development] iGoOsE76:

been running it since the AM and it's been like you described...
[HD2 Android SD Development] clio94:
The new battery driver makes the difference.Before my battery was close the phone in 15-20%.Especially when playing angry birds.Now it reaches 0%.The first time i am playing angry birds with 1% battery. :p
[HD2 Android SD Development] jzibit17:
Ive been reading different post and im confused about MAC-address... First i don't have that command line under my start up txt and i want to install the 7.8 kernel. Before adding the command line i want to know whats the patch is for. Is it for people who cant connect to wifi or people who own two hd2 and are using the same build & kernel under the same router? Pls clarify for me :) thanks
[HD2 Android SD Development] the_scotsman:
Hastarin says in the OP that underclocking with SetCPU doesn't work in V8...I don't think it's needed anyway. I only lost 5% or so last night when I was in bed. NO different than when I used to underclock it to 245 with screen off :)
[HD2 Android SD Development] pablo71:
Current at 62ma no matter what i do? Why?

So confused why many report 5-7ma current draws with wifi or data on. No matter what I do pull over 60ma? Tried lots of things. Going into airplane mode before booting, applying lights fix correctly, different setcpu settings, using correct tun.ko and bsm__.ko modules.... Very happy android user with major appreciation for all devs work, just hope someone knows how to help curb my power consumption and maybe other users can benefit too. Thanks for all the help.

[HD2 Android SD Development] JonSolo:
This is a great kernel. Cannot tell honestly about battery without a few days use...nor do I believe anyone really can till you put it through the ringer a bit. (just an opinion)

Also the Wifi set mac address works great...all of my HD2's are on wifi live now, which is awesome.

Last but definitely not least...no data drops since the upgrade!!!!

[HD2 Android SD Development] captainhakan:
your last kernel r8 is far better then all other previous versions. i don't understand exactly what made the huge diffence but please keep it this way hastarin :)
[HD2 Android SD Development] Cerv3r:
My battery seems to be dying fast with r8
[HD2 Android SD Development] tinuz97:
Just copy the root folder that is in the package from hastarin,untouched,IN the Android folder on the SD card,do this with a computer....put the SD card back in the phone,boot.....tadaa! Auto copy to the system folder.Works great,no need for rootexplorer.
[HD2 Android SD Development] mwebb76:
Pablo71, Pagnell,

QUIT WHINING AND TURN OFF YOUR GPS. FFS LEARN TO SEARCH.
[HD2 Android SD Development] slbenz:
Hastarin, your new v8 seems to be using the same standby use as your 7.6 for me. 7.7 gave me problems with standby use until I changed my WM ROM from Energy Stock Sense 2.5 to Energy Reference, then the standby use was the same as 7.7 and now 8. So all of your kernels are giving 5mA standby use as an FYI. Also using 2.15 radio. Great work as always.
[HD2 Android SD Development] the_scotsman:
V8 seems to be fantastic!

Battery use is the same as previous versions, and I have UNINSTALLED SetCPU for the first time ;)
[HD2 Android SD Development] hastarin:
First thanks to everyone that's responded. I'm also very pleased with r8 myself. Like someone said, maybe it's placebo, maybe it's the video driver changes, but it just seems smoother/faster despite no overclock.

None taken. Sorry if it seemed that way. I've been suffering from insomnia the last few days, and that post was written after 4hrs sleep. I've since got another 3. :p Let me know how you go with removing ipv6 I have a feeling I'd tried it previously with no luck.

My problem is that every release someone makes a claim like this. They inevitably tweak/change something, reboot 3 times, or whatever, and then find that magically it then has low drain like everyone else is seeing!

So you're telling me you're using EBL with a 3 second timeout and still seeing the high drain in standby?

Read the original patch authors details here:

http://xdaforums.com/showthread.php?t=819819

In short it's so you can get a "real" MAC address (by copying what you have under WM). It's needed for households with more than one MAC address and for those that may need to provide their MAC to their work, etc

NOTE: I haven't bothered with the BT address myself.

Umm, no where do I recommend turning GPS off. Though I have read of issues with GPS on certain builds.

Again, did you read my FAQ and are your running EBL with a 3 second timeout?

If so and you're still getting high drain have you run System Panel Lite to see if you have a process using more CPU time than it should?
[HD2 Android SD Development] mwebb76:
I never said you recommended it, but it's a common problem with all HD2 Android builds and it affects your kernel too. (Or did, at least in the 7.5-7.6 era. I've not tried it on 7.7 or 8 because I've solved the problem by not leaving GPS on.) 60ma battery drain in standby is an indicator of the problem, and at least one of the posters I replied to mentioned exactly that.

I'm suggesting people do some basic search and troubleshooting themselves, rather than moan about your kernel. I don't know that you've helped yourself by smacking the suggestion down - I think you've probably set yourself up for another couple of dozen posts about battery drain from people who insist on leaving GPS on all the time.
[HD2 Android SD Development] apallohadas:
I've also uninstalled SetCPU for the first time. Oddly enough that seemed to completely smooth things out for me.

I'll say it again... Good work!

For all the new guys asking repetitive questions:

I know that searching can be a pain in the rear, so give this a try when that fails, start reading the thread back to front. Sometimes someone else will have just asked that same question because the build was recently updated.

Good luck fellas.
[HD2 Android SD Development] trangoul:
indeed brother :D
[HD2 Android SD Development] Cerv3r:
Yes but the problem is that I want to limit the phone when the screen is off to 245.. It saves me a lot of battery when playing music
[HD2 Android SD Development] kahiro:
thanks hastarin for another great kernel! this is by far the best on my device. been using yours since the very first version and this is the only one i can say flawless. with previous version data is very unpredictable but so far no drops for the last 10 hrs. well there were long pauses (5-20secs) but it automatically restart so i can live with that. thanks again.

since you're not taking donations i'll double my monthly contribution to worldvision.com.au this month :D
[HD2 Android SD Development] Blades:
Well, it worked. Kernel went down to 2.56 MB. I -think- this kernel may also be built with the useless tuner drivers removed. I too, am going on little sleep, and I cannot remember. Commented out all ipv6 and inet6 associated entries. There's probably a little bit more to whittle down without any consequence... but its time to punch out and get my 3 hours of sleep in.
[HD2 Android SD Development] fi3ry_icy:
errm, so the R8 release totally renders SetCpu useless becoz it blocks all over/underclocking from occuring? i'll have to go back to R7 to save my battery juice.. :(
[HD2 Android SD Development] the_scotsman:
Why do you have to go back?

You should at least try it...myself and several others have stated that battery use with this one (without SetCPU) is the same as previous versions with SetCPU running.
[HD2 Android SD Development] jmmmmm:
I too will confirm battery usage is just as good as 7.7. Very low on standby.
[HD2 Android SD Development] hastarin:
Well I'm one of those people and I don't get that drain, hence why I say a high drain from leaving GPS on is probably an issue with only certain builds.

I have only ONCE seen high sleep drain on my phone. As much as I hate answering the same questions over and over and over and ..... I also don't want to mislead people.

You might think it does but I think you'll find it's a "placebo" affect. The CPU only speeds up when it needs to.

I am taking them now, but just as happy to see the money go to them. :)

I'm still managing to get the smd_tty loop here, so that's definitely a priority for me to look into atm, along with the extended battery support.
[HD2 Android SD Development] sorodrigo:
done an excellent job

wait the version for my extended battery

Greetings

:D:D:rolleyes:
[HD2 Android SD Development] hastarin:
Thanks for the feedback. I don't know of any reason our phones would need the ipv6. I'll see about doing the same for testing myself.
[HD2 Android SD Development] gumataotao:
So far so good. Great job Hastarin :) The only problem I have is now what do I put into the empty slot on my home screen where set cpu widget was lol.
[HD2 Android SD Development] hastarin:
CIFS/NFS support - is anyone actually using it?

If you're an average user you probably don't even know what they are, so if you're one of them feel free to ignore this.

But if you use CIFS/NFS read on.

First, I'm considering dropping support for NFS in my next release.

So if you're actually using the NFS support in my kernel please let me know ASAP!

Based on how many responses I'll decide if I'm going to keep it as a module, or drop it completely.

I'm also planning to move the CIFS support to a module. If a build doesn't have enough free space (297KB) in their system.ext2 then the user will have to switch to one that does (the one I'm using does) or live without the CIFS support.
[HD2 Android SD Development] will3k14:
Thanks a lot for these Kernel's thwy are quite awesome. Keep up the good work.
[HD2 Android SD Development] songokussm:
the bad:

something is wrong with the video driver in r8. my quadrant score is 436. Normally its 1700+ my G1's quadrant score is 335.

During the test i get 2 - 7 fps.

if i switch back to 7.6 i get 40+ fps.

the good:

amazing battery life and very stable.

2h 49m and im at 98% battery life with general usage.
[HD2 Android SD Development] the_scotsman:
Quadrant is completely unreliable...please don't base your opinions on it...try games you normally play...if they still perform the same, then you have no problem.
[HD2 Android SD Development] sterz85:
on the desire HD build, youtube works but when i switch to HD the video starts skipping

would this be related to the kernel or just the build itself?
[HD2 Android SD Development] the_scotsman:
That's a known issue with the HD builds.
[HD2 Android SD Development] monyozt:
replacing haret.exe and zimage to v8, my phone stuck @ HTC logo while boot on android
[HD2 Android SD Development] the_scotsman:
Pull the battery out and run it again...it will work maybe after 1 or 2 tries :)
[HD2 Android SD Development] Macelangelo77:
There was a file lights.qsd8kso.so in the folder, so that's why I renamed it likewise. I'll check on the Mdeejay FroyoHD 3.7 thread. Thanks for noticing.

Sincerely,

Mac
[HD2 Android SD Development] Macelangelo77:
Anyone using the Wifi MAC-patch and confirm it's working? I've had no luck so far with Mdeejay FroyoHD v3.7 and there's really not much too it, expect for entering the correct address in startup.txt (see link above), so I can't figure out what went wrong.

Sincerely,

Mac

2.14 radio vs. 2.12 radio

I noticed a couple of people are now using 2.14. Has anyone upgraded to 2.14 from 2.12 and noticed any changes, good or bad, from the uprade? Thanks.
[HD2 Android SD Development] mfish123:
Feedback on kernel #3

I'm running Mattc 1.8 (clean install with apps and data restored with titanium back up) with kernel #3. Prior to this, I tried Mattc 1.8 with the non-evo kernel (kernel that comes with the build) and had issues with it that I had with Mattc 1.7. I then tried Mattc's evo kernel (releasesed 09/19) with his 1.8 sense build and saw immediate improvements. I'm on Chuckydroid rom and radio 2.12.50_02.

Hastarin - your kernel is top dog. All the same things that work with Mattc Evo kernel work in yours, but yours is faster (higher quadrant score and more responsive to my inputs). Also, I think battery drain may be better - I'm 5ma with screen off. I use similar setcpu settings to you and use juice defender.

My only gripe is the camera flash delay but you're aware of that.

*****Also, a couple of times I received an incoming call and when I slid the slider to answer the screen locked up, call went to voicemail, and showed as a missed call. After it stopped ringing the phone became responsive again. I had min cpu speed set at 245. i've increased it to 576 to see if that helps - working so far but haven't had a lot of incoming calls to test with it.******

G-sensor seems better - I played teeter to test it and it was accurate although when I calibrate it one of the bubbles just stays at the end of the tube after done calibrating. Auto rotate which I really don't use is very slow to respond - when web browsing it takes a good 10 seconds for screen orientation to change.

I don't get stuttering with music or videos. Bluetooth, GPS, Wifi, and Wifi tethering. No more hard freeze when re-enabling 3G. No SOD's, no lag, no being lazy to wake up, no having to hit end button and then unlocking screen to get out of a freeze. Data is fast (2500 kps d/l on 3.5g).

I'm very happy. Keep up the great work. I hope this feedback is useful.
[HD2 Android SD Development] hastarin:
I see know reason why changing the kernel should cause that. I guess it must be something peculiar to the build.

Camera flash delay is something all the EVO kernels have AFAIK.

The lock screen issue isn't something I have but I don't get that many calls. I'll try to remember to call myself a few times today when the phone is asleep. Maybe give it a second or two before sliding. When the phone first wakes up load will jump, and CPU will jump to whatever max it can based on your SetCPU profile, so it may be unrepsonsive for a bit, similar to when you first boot.

I have noticed some touchscreen issues lately but they were due to CPU and/or I/O maxxing out. I've bought System Panel to see if I can track the offending processes down.

To everyone else I haven't quoted, thanks for the feedback, and to those with WiFi problems double check you've updated the modules correctly, then toggle Airplane mode on/off, then try WiFi.
[HD2 Android SD Development] aussiebum:
Hmm, I can start up Wifi and connect to a unsecured network, but earlier this morning I was having trouble connecting to my own home WPA-secured network - it was doing a Connect-Disconnect-Connect-Disconnect issue that I'd seen previously when Wifi firmware was out of date and I was trying Michy's r11 kernel.

I am using the latest (aug 31st) wifi firmware now though and wifi module is definitely updated to what you attached in your package.

Will try connecting to my home WPA network again after work.

This is on Darkstone's HD2Froyo 2.1, modified to use PPP using your #3 kernel.
[HD2 Android SD Development] mfish123:
Thanks for looking into that for me. I just upgraded my radio to 2.14.50.04 and voice quality is still good. Signal strength improved from -83db to -63db. Hopefully it won't be at the expense of battery life.
[HD2 Android SD Development] fatrix1:
Thank you very much

[HD2 Android SD Development] lippa:
#3 release, no echo. Working perfect! Thanks!
[HD2 Android SD Development] hastarin:
I really can't see why this would happen. I have not changed anything with regards to WiFi (over the kernel that came with the Desire HD Beta 2) and am using it on my home network (WPA-PSK) just fine.

The new modules should have a timestamp of (22-08-2010 19:22) in your /system/lib/modules folder. If they don't perhaps something has gone wrong with updating them and you need to try an alternative method to update them.
[HD2 Android SD Development] ridikolous:
radio 2.14 has high battery drain but good signal. with radio 2.10 i was on standby at 3ma now im at 54 mA. imma give it a couple of days to let it cycle thru.
[HD2 Android SD Development] lippa:
What app do you measure this with?
[HD2 Android SD Development] aussiebum:
Hmm, the modules that came with #3 that I installed have a timestamp of 22-09-2010 19:41.

Do you mind attaching the modules you have onto a post so I can compare? I can't use any of the d/l services from work. Thanks
[HD2 Android SD Development] aussiebum:
Current Widget? It's awesome. On a side note, 54ma standby drain sounds like you just need to restart-launch Android again with keypad lights on.
[HD2 Android SD Development] hastarin:
Sorry I'd just woken up when I posted that. 19:41 is correct. :o
[HD2 Android SD Development] aussiebum:
Thanks for the confirmation :) It's weird why it didn't want to connect then... well guess I'll find out when I get home whether flicking airplane mode helped. If not will also try #2.

otherwise pretty awesome kernel. bluetooth doesn't work for me either atm, but I guess just need to poke around a bit to fix that.
[HD2 Android SD Development] noellenchris:
Figured I'd give this a try #3, but echo is still there and exactly the same. Seems like it gets worse if I move the phone. If the phone is laying flat seems to be better. Tried disabling the gsensor but no change. Don't know why, but oh well, hopefully it will be fixed soon.
[HD2 Android SD Development] zoth:
Great Kernel

Using it right now everything is great as my SIG. Thanks a lot.:)
[HD2 Android SD Development] hastarin:
Have those with the echo problem tried any other EVO based kernel (such as those mattc has used in his latest builds)?

I'll try to put up a version of my kernel minus the gain changes (ie put them back to the same as git) later today.
[HD2 Android SD Development] noellenchris:
since the evo kernels came out, I thought others had this issue too, but later learned only some had this issue. Seemed like those running sense builds don't notice. I've ran gauner1986, Cass, LeTama's. I'll check with Cass, and see if I can try his. He runs CM6 and I don't think he has any mic problems. Thanks for trying to help.
[HD2 Android SD Development] Beefheart:
Politely **** off. Firstly, I'm not whining and secondly you really should't assume people are so stupid as to have the GPS turned on if they're having issues with battery life.

Hope this helps.

Yes mate. However, now I have gone back to 7.7 I'm still getting a 60ma+ drain in standby no matter what I do so it must be an issue with my build. So I'm going to start with a fresh one today with R8. I'm sure that will solve the issue.

Like I said, I wasn't being derogatory to your kernel.
[HD2 Android SD Development] siksy:
have no compass :(

I've the same problem (hastarin r8)..Tried with GScript Lite with no success:(

Any help? How to make a compass alive :(
[HD2 Android SD Development] xda-member:
This kernel is great...works fine under Meedejay Revolution Evo 2.2...

Battery consumption is the same as 7.7..I get around 5-7am in standby..

Quadrant speed has decreased but not that bad cuz everything is running flawlessly !

Well done, keep going.
[HD2 Android SD Development] white-energy:
I hope you can continue to 7.8

the 8 is just horrible.. its a powerhungry B***h
[HD2 Android SD Development] Svendrae:
Hello,

v8 is awesome, great speed, very stable and a long battery life on my HD2 with MDJ FroYo HD3.7.
[HD2 Android SD Development] vegaman:
Interesting, for a while now I've used tasker to automatically turn GPS on when I start programs that need it, and off again when I quit them. So this isn't really necessary to reduce battery usage?

I'm actually yet to try r8, reluctant to move away from my overclock lol. I'll probably try it soon though.
[HD2 Android SD Development] Showtime7:
I'm having great results with r8... Before I could only download if I was in HSPA range. Now both HSPA and Edge works and the HSPA is fast! Everything else works as it should, this along with MDJ's evo build is a near perfect combination.
[HD2 Android SD Development] mda4man:
I like this kernel only problem is once fully charged the battery gets quite hot...never use to happen so my only guess is the new battery driver (which as it goes works almost perfectly extept for this problem). Can anyone else confirm if there getting this?

Hastarin this driver does stop charging at 100? I remember this was a problem with the old driver a long time ago which caused the battery to heat up
[HD2 Android SD Development] JamesRC:
Hastarin, with perflock, do the governors in SetCPU take effect?
[HD2 Android SD Development] securecrt:
the answer is no
