No problems

I haven't had any problems with Hastarin r8 so far. My batter life has gotten a lil bit better, quadrant score dropped, but everything seems to scroll smoother. I'm using Mdeejay's rEVOlution. I haven't even had not one data drop yet, (Hoping I won't get one!:D) Keep up the good work Hasta. I'll continue to use r8 for now!
[HD2 Android SD Development] vessk0:
With this kernel, I finally have a stable WI-FI / data connection, which is the best for me. I wait only for overclock version soon. :)
[HD2 Android SD Development] siksy:
Everything is working fine (Mdeejay's rEVOlution 2.3 + hastarin r8) but where is the compass?
[HD2 Android SD Development] JonSolo:
Battery does seem a little worse than 7.6 (skipped 7.7).

But for the most part (corn warning, corn warning, corn warning) r8 is Gr8 (end of corn warning). :p

[HD2 Android SD Development] hastarin:
Sorry, the information I've posted is from Rajko (the guy that got compass working) and I have no more information than that. My compass is working on my build. I honestly can't remember if I actually deleted the file or not though.

On Sense builds at least, unless an app requests an exact fix of your location (assuming you have the "Use wireless networks" setting disabled, and at least one of either phone/wifi turned on) the GPS will only be powered on when it's needed. I haven't used CM6/MIUI so can't comment on those.

Honestly r8 seems smoother to me. The overclock makes VERY little difference.

r8 Benchmarks (for what little they're actually worth):

Quadrant 1612

Linpack ~33.5

Neocore ~30.8

Compare those to extreme overclocking here:

http://xdaforums.com/showpost.php?p=8720613&postcount=1258

You'll note that in Neocore (perhaps the best example of what a game might be) the difference is less than 1fps!

Personally I don't think <1fps is worth the risk of damaging my CPU! ;)

The driver in 7.7 stopped when the battery was taking less than 5ma and recalibrates that as 100%

The new driver is quite complicated and I haven't made sense of it all yet. It's using the same algorithms from the Ace (Desire HD) kernel so it should be fine. Mine definitely turns off when it reaches 100%

Shh. Yes. ;)

Are you positive you're running r8, using "mac.address=", and updated the modules? It definitely works for me. I guess it might be build related, though I can't imagine how.
[HD2 Android SD Development] elite_gamer04:
So many conflicting reports of Battery :( haha.

One quick question, currently using HyperDroid 1.7 which is running RMNET by default obviously - if I want to use this new R8 version does that mean I also switch to PPP?
[HD2 Android SD Development] hastarin:
Yes, though the majority are saying it's fine. :) I just know my current widget log still shows 7-9ma drain in sleep. So really, the difference, presuming there must be some due to no undervolt, is extremely minor! Whatever the difference it's not worth potential instability from undervolting.

You'll have to switch the build to PPP first. Search the build thread for information on how to do that. Or, from what I've read, you can donate to pongster and he'll send you his special version that includes a script to switch to PPP and other tweaks.
[HD2 Android SD Development] noellenchris:
BATTERY DRAIN ISSUES?

ok, Hastarin's kernel will not cause 60mAH battery drain in standby.

If you discover such drain do this.

1. use an app to view what is using the CPU

2. kill whatever is using the cpu except acore

Most likely you'll find something using cpu in standby or a hung app. I know for me, I had these issues and it was caused by email.apk it kept using about 50% cpu and if I killed it, and went to standby I only had about 5mAH drain. I eventually upgraded email.apk as a new cm6 nightly came out.

You may find a similar culprit as the evil battery drain king in you cpu user list. So troubleshoot your build as we all have something different going on at any point and time.

If other report low drain in standby then it's not the kernel, it's something you have running....not hastarin's fault....:)
[HD2 Android SD Development] elite_gamer04:
Thanks for the quick reply Hastarin, the HastarinEVOKernelPatch folder included in the Donation build has alot more files then the standard R8 download - libbluedroid.so, build.prop etc

Wondering if/why they are there? I've found the PPP script (includes a file that goes into Root) and I'm assuming after that simply copy across R8 Files, but still lost what those extra files/folders are for.
[HD2 Android SD Development] Macelangelo77:
I'm running R8, I'm sure. I'm using "wifi.mac=" as you advised earlier. I updated all the modules. I even made a fresh install yesterday, after which I replaced the modules again. So, I have:

set cmdline "bt.mac=00:11:22:33:44:55 wifi.mac=00:23:76:cb:5b:47"

Have you implemented v1 ("mac.address=") or v2 ("wifi.mac=") of the patch? I'll try mac.address, to see whether that works...

Edit: tried mac.address, no luck either. I'll ask over at Mdjeeday's thread to see whether there's something in his build that prevents the change.

Sincerely,

Mac

volume too loud while phone call

Hi,

someone else a problem with too loud noise while phone call?

Although I switch to the lowest volume level, its too loud.

Is there a solution for this problem ?:confused::confused:
[HD2 Android SD Development] northern247:
I had a complaint that the Mic pick up is way too loud too picking up every little bit of background noise :(
[HD2 Android SD Development] noellenchris:
try searching for default.acdb on xda , you have to rename the default.acdb files on your build, I'm pretty sure it's for cm6 builds. I forget the folders. I posted the directions a few times...so just search and you'll find your answers...:)
[HD2 Android SD Development] Agoattamer:
Here is the thread that noellenchris talked about. It fixxed the issue for me when running froyostone3.1 and hastarin r7_7 and r8

http://xdaforums.com/showthread.php?t=805002&highlight=default.acdb
[HD2 Android SD Development] hastarin:
v1 in r7.7, v2 in r8

I'd suggest trying:

set cmdline "bt.mac=00:11:22:33:44:55 wifi.mac=00:23:76:CB:5B:47"

I have no idea if it's case sensitive but noticed I have used capitals in mine.

No idea, you'll have to ask pongster. I haven't even seen that build.
[HD2 Android SD Development] LordDeath:
I just upgraded from r7.7 to r8 and this introduced a new problem:

While listening to music (Winamp) or podcasts (Google Listen) the sounds stops for a short period every time I wake up the device from standby. This did not happen with r7.7.

I am still using the default.acdb file because otherwise the sound is too quiet.
[HD2 Android SD Development] eyanlaya:
Did anyone notice that the light sensor is not working???? Mine is not working...
[HD2 Android SD Development] plotzkella:
Mine is working flawlessly... :)
[HD2 Android SD Development] eyanlaya:
Oh ok it's working now... but until i wake it up after changing the setting... haizzz... paise...
[HD2 Android SD Development] d3l1:
Well after one day of usage the battery drain in standby is at a constant 9mA and my data connection doesn't crash like before, but sometimes it says I'm connected but browsing gives me a "network error". No need for airplane mode though. Had no time to test mac-hack or the music stuttering issue.
[HD2 Android SD Development] curiousGeorge:
My FPS with v7.7 at 998mhz were 25.14, and overclocked to 1.15Ghz FPS went way up to 30.11.

With new 8, fps is limited to 25.01. I understand why overclocking can pose problems -- but why not let the user decide? If it defaults to 998mhz, there's no harm in supporting up to 1.15Ghz if the user wants it. "No benefit in day-to-day use"? Don't you play any games? :)
[HD2 Android SD Development] ChrisM001:
New hastarin r.8 doesn't work stable in any of my builds:

- random reboots in Darkstone's HD2Froyo V3

- force close/wait messages an lags in Froyostone 3.1/3.2

Moreover music stuttering after startup, not working pppd-fix.

I'm going back to 7.7 for now.
[HD2 Android SD Development] Sp33dlink:
This biuld worse in battery consumption than 7.7 on my device!

My drain in usage is way higher than normal (around 300mA)

My drain in standby is higher than 7.7 (9mA instead of 3-5mA)

EBL doesnt help me with the 60mA bug.

Im using the 3sec delay...

bit disappointed but looking forward :)
[HD2 Android SD Development] hewlett777:
Same problems here, first new zimages I've bothered using in a few months so its nice to have the button blacklights working and auto dim, but no notification leds and poor battery performance.

Might drain the battery, charge on 'off' and see if that helps, appreciating the effort all the same :)
[HD2 Android SD Development] jmmmmm:
Did you give it some time to settle down or did you do the "load, boot, check battery" drill? This almost always results in seeing a higher drain than previous. Give it some time, charge the battery fully and let it set in the standby state for a while. This always works for me. After a few hours it settles into the single digit mA on standby.
[HD2 Android SD Development] vivoniq:
I really want to like this...

...but it's not working for me.

I'm SO grateful to Hastarin but for me this build eats my battery and is not as responsive as 7.7. In particular coming back from screen-off.

I also loved previous releases with a clocked and non-clocked version; for me the clocked version worked every time.
[HD2 Android SD Development] Sp33dlink:
now theres a 6mA... i will test it some more hours...
[HD2 Android SD Development] jjblaster3:
remove perflock

hello.. thanks for the awesome kernel, r8 is gr8..

i was jus wondering if you could remove perflock (In the r8 version) for the ability to underclock..

this is because at 998mhz using all governors(we can "slightly" exclude powersave) the temp of the battery gets rily high when charging..

also battery drain on normal usage with interactive is quite high, and switching to conservative gives abit of lag (powersave is not an option as the slowness dominates here)

i used to run it at 652mhz (interactive) on previous versions and none of the above used to bother me..

hope you will consider this..thanks
[HD2 Android SD Development] khanem:
r8 screwed my connection. back to 7.7.
[HD2 Android SD Development] clio94:
I also see this.Battery drain from 4-6ma now is 7-9ma.But the battery closes the phone at 0% instead of 15-20% before

Also i dont have 60ma bug.
[HD2 Android SD Development] sxypapi:
very stable, but it eats my battery like the cookie monster eats a cookie,lol

no biggie,just ill go back to 7.7, still hastarin thanks for ur work always :D
[HD2 Android SD Development] pablo71:
your passion that people know how to read is admirable. If had read my entire post you'd have seen I figured out what I needed to do and added that for the rest of the community to search read and benefit from. seems these builds and kernels like some time and reboots to settle in, aside from gps or sync being on full time. And I am getting excellent power consumption from this r8 kernel.
[HD2 Android SD Development] supermantxz24:
with the r8 kernel everything is great except for one thing i am using froyostone sense v 3.2 my mms are fine like i can send mms and recieve mms but sometimes it wont let me type my mms to send it. is anyone else having this problem. lastnight it was doing it alot but today i havnt had any issues yet.

[HD2 Android SD Development] motoman234:

[HD2 Android SD Development] vegaman:
Thanks for the info :)

I'll try r8 with a sense build today and see how leaving GPS on goes
[HD2 Android SD Development] curiousGeorge:
Any software-rendered application (not GPU/RAM/IO limited) can see up to a 15% increase in performance with the overclock. The increase of "less than 1fps!" is due to the graphics chip bottleneck in which CPU performance is not an issue anyway. For all other purposes, the overclock is very useful. Also, when maintaining proper temperature ranges, overclocking a CPU has a very minimal effect on its longevity -- your phone will be in the garbage long before the CPU will die.

A similar argument can be raised in favor of undervolting -- reducing heat and power consumption can have a very significant effect on battery life. People in here (including myself, now that I've tested) can report greater battery draw with r8. All things equal, a kernel at the same speed (998MHz) that draws significantly higher voltage will drain the battery faster. There's a great wikipedia article about voltage and power draw -- it's not a linear function; it's much more potent.
[HD2 Android SD Development] hastarin:
OK this is getting old. The difference in standby from 7.7 is 2mA (7-9 vs 5-7).

Our battery is 1230mAh. It is 0% at 500mAh. That gives us 730mAh of useable battery. You do the math for how much difference that extra 2mA drain makes!

No sane person can argue that undervolting and overclocking at the same time leads to greater stability. I want as stable a kernel as possible for troubleshooting the remaining issues we have (like data dropouts).

I will consider releasing a kernel that is undervolted, overclocked, etc when the various issues with the kernel are fixed. Until then please either respect my decision or build your own kernel and start your own thread to support it.

I won't be posting again about this. :rolleyes:
[HD2 Android SD Development] Gary.M:
Hastarin which build is the one you call "mdeejay Froyo Sense v2.0 Clean"

I can only see a v1.1 clean in the "Froyo Sense Series" thread.

Thanks....
[HD2 Android SD Development] dubie76:
Just to report that I used r8 with froyostone and have been getting call drops and data issues. I will be dropping back to 7.7. Dont know if anyone else is having anything similar.
[HD2 Android SD Development] hastarin:
AFAIK That's the closest to it as he hasn't released the 2.0 to the general public yet. I need to update my sig, I've just updated to 2.1 now too.
[HD2 Android SD Development] eenbox:
Ok - gettin irritated now...

shubcraft 2.0 with packed kernel ElBartoMe (not sure what the name is) - echo in calls;

hastarin 7.7 AXI - drops in data and iffy WIFI and black-outs; battery life not the best; GPS required;

hastarin r8 - unbelievable black-outs (no return from wake-up)

hastarin 7.7 alt (no AXI simple hastarin 7.7) - data drops, black outs continued - changed on Tmobile ROM every possible setting -= no changes... unbelievable...
[HD2 Android SD Development] dj_ghosie:
Very nice update indeed! First noticeable difference is the booting up. I'm using darkstone's desire sense built. The bootup screen used to be sluggish 'quietly brilliant' squabbling but now it's as smooth as the window booting. Generally it seems smoother too.

As for the improvement, is it possible to tweak the charging pattern? When charging from almost dead, the percentage goes up very quickly but gradually shows down as it reaches higher percentage...

Overall great improvement, thanks!
[HD2 Android SD Development] apallohadas:
Your blackouts are from the auto-brightness probably. I've been using r8 with 2 different builds now (phireMod and HD2Froyo) and the first thing you have to do it kill that auto-brightness setting. Oh, and some builds require you to hit the call key to wake it up.
[HD2 Android SD Development] eenbox:
I'll try with green button instead... auto-brightness is turned-off in both Android and WinMo...
[HD2 Android SD Development] hastarin:
I can't see why you'd get black outs without using auto brightness. Try putting the screen under a light bulb when it happens. If it suddenly shows up then auto brightness isn't disabled for whatever reason.

Why would you tweak it? That's how the battery charges.

When it's almost flat it takes current easily, but as it approaches full it will take less and less charge.
[HD2 Android SD Development] eenbox:
Sorry for the negativity - I do not think that black-outs have anything to do with Android, kernel, etc - it's simply this Windows Mobile crap... I disabled rotation and auto-brightness too and it just drove me nuts - black outs one after another... it finally calmed down ... BTW I love hastarin r8 - battery is kicking into 6mA easily (stand-by of course)!!! Great job mate!

UPDATE: aaaand it was of short life - dunno if I jinxed it or what I did BUT: SODs like crazy again; besides SODs I now have reported echo's in phone conversations - so just another problem to deal with.

I am not sure why but 2.08 radio (2.10ROM) and 2.10 radio (2.13ROM) are simply not playing along with any hastarin kernels... sigh
[HD2 Android SD Development] motoman234:
That really sucks, I know how annoying that can be. Maybe it has something to do with the ROM or radio your using? I've tried r8 on quite a few different builds and have not experienced one blackout or SOD. Then again I haven't had SOD in well over a month. Try my setup in my sig if you can't figure anything else out.
[HD2 Android SD Development] hastarin:
I've had a look in to this.

As best I can tell, it is related to the differences in the display driver (msm_fb).

Hopefully one of the core devs will be able to take a look at it and fix it, though I'm sure it won't be as high a priority as some of the other issues. ;)
[HD2 Android SD Development] atticus182:
I have the same 'issue' but I really can't be bothered, it's just minor skips and only when you wake your phone up :)

R8 is running fine hastarin! Great battery life and smooth animations, chapeau :D

Are you guys working on extended battery support for r8 already ?

[HD2 Android SD Development] Macelangelo77:
I've tried just about everything, capitals, lower case, command line options from v1 and v2, but I can't get it to work with mDeejays v3.7 with r8. Apparently Hastarin has it working but the build he uses is not released to the public. I haven't had any response whether someone with mDeejays v3.7 has it working. From what I understand, it might be something in the build is preventing the patch from working. I don't know what build your using, but give it a try. It might help to find out why it's not working for me ;)

Is this still required in startup.txt?

set cmdline "rel_path=Android nand_boot=0"

I dont think it was in the original file in shubcraft 2.0 when i downloaded and updated it, but i used my old startup.txt with that line still in there. I had a thought that maybe thats why its taking alot longer to boot and gain signal in newer releases for me, on both sets
