SR2 work great for me under Froyo..only this latest RC11 does not work
[LG Optimus 2x] tablighs:
I was just quoting what spica said. :)

Have you tried RC9 before? Because it is the first kernel spica made from official 20L sources. SR2 was released prior to that.

I personally think that anything released from now onwards will not be compatible with froyo anymore unless spica made an effort to make it work on both froyo and gingerbread.

Cheers!
[LG Optimus 2x] kosi2801:
Installed PP9, RC11, PP9 again (after initial testing). Coming from RC9 + stock ROM, Busybox installed.

init.d (and therefore also the ramzswap) is still not working/active. Running UV -50mV, OC 1.4GHz with System Tuner as working stable with previous RC9. No lockup so far after ~12h of usage. Battery usage seems a bit better to me compared to RC9.

Keeping RC11 although init.d still not working.
[LG Optimus 2x] feav:
spica,

Why did you use num_devices=4 in systweaks script? I've found this instruction: http://code.google.com/p/compcache/wiki/Scalability

Maybe we should use num_devices=2?
[LG Optimus 2x] Kenks:
supported kernels

spica, you mentioned before there will be 3 type of kernel.

without O/C, without voodoo,

without O/C, with voodoo,

both O/C and voodoo support.

Did you give up from this or release in next time ?
[LG Optimus 2x] Lo_RaT_PeNaT:

yep, would love to see a non oc/uv version too
[LG Optimus 2x] abwyatt:
Great work again Spica1234! Absolutely stable and great battery power performance. Then again, that was the case for me with HP11 rc2 :D

I agree with your later observation that the zRAM 'feels' slower than the previous CompCache.
[LG Optimus 2x] spica1234:
Ok i ll release RC11-R with faster observed Compcache with 2 versions one with OC/UV and one W/O OC/UV:) Give me sometime today to fix it.

For most commonly asked question about no init.d(which infact is unrelated with kernel), follow these steps in respective order that will solve init.d not working along with swap:0 issue:

-backup all your user apps through titanium backup

-reboot in recovery

-nandroid backup

-wipe data/cache

-format system throught mount option in recovery

-wipe dalvik-cache

-install stock rom/rom with which problem you face

-install RC11

-install pp9

-reboot

-after it starts for the first time download busybox,install latest busybox version

-reboot and check whether init.d/swap works? Zipalign won't work cause to zipaligned it needs binary zipalign which isn't shipped with rom

-if everything does work than restore your previous data apps only w/o data with titanium back

-reboot

Thank you Marry Xmas and advanced HAPPY NEW YEAR to everyone:)!
[LG Optimus 2x] abwyatt:
You are absolutely marvelous the way you respond to your users!

HAPPY NEW YEAR ! (in advance :)
[LG Optimus 2x] psionic2k:
Hi spica,

thanks for your help.

I had to reinstall RC11 as last step as the PP9 overwrites the systweaks script. But after that swap is working :).

Thank you for your great work. Have a great new year.

@Spica

Is it too much to ask for a strong vibrator version? Thanks :)
[LG Optimus 2x] baltac:
@spica1234:Today I've upgraded to last official FW and rooted an LG P920.

While doing some test, I've seen using terminal emulator, that it natively support for swap file and the free -m command tell me that the RAM size was about 410Mb, and the swap file was about 120Mb.

Maybe there's a proportion to be observed between the amount of RAM and swap file size, because the service is efficient.

To test it, I've installed the backup of all my apps + data that I own in my P990, and despite having several applications open at once, this did not affect the fluidity and responsiveness of the system.

Perhaps you already know all these things (I'm following your thread, only since 3 days ...), but you may look how the LG P920's kernel works, to understand how the cache is managed.

I hope this is useful for your work. :)
[LG Optimus 2x] kosi2801:
Had RC11 running stable for some time now. Today I drove ~200km with	Bluetooth to car and GPS. Locked up twice a few minutes after Bluetooth connected. Rebooted once after ~4min in GPSTest.

Sadly back to RC9 after all..
[LG Optimus 2x] SuperSkill:
As I now can post :)

Happy new year Spica(and all of you fellows here), AMAZING kernelwork youre doing, been using since start. I guess we still should flash kernel before powerpacks?? Keep up, we need people like you, thanks alot.

HAPPY NEW YEAR EVERYONE:

NEW Revolutionary HP RC11-R is out: for more changelogs and download details reffer first page. It's with OC/UV eventhough I've modified cpufreq driver so that 2nd core cpufreq steppings move in slide with 1st core. Now you can see 2ns core activated in notime and with scaling same frequency alike first cpu. and when unneeded it suspends 2nd core in notime.
[LG Optimus 2x] hakankarani:
Thanks mate downloading now. Can we change bpp in Rc11R cant find the file..
[LG Optimus 2x] spica1234:
yeah ofcourse I alwas forget that thing to add.

add this line below in the beginning of bpp file. in /system/etc/init.d

aftr /system/bin/sh

for 24bit 16 million colors,

echo 24 > /sys/devices/virtual/graphics/fb0/bits_per_pixel

for 32 use echo 32

permissible fb supported values are 16,24,32,48,64

more higher bpp conserve more memory resources

at value 48 you can drastically notice more saturated vivid red/green/blue colors as I've patched tegra framebuffer for pseudo support you will notice black is more black red is more saturated red and same applied to blue and green in specially HD images and HD videos:)
[LG Optimus 2x] spica1234:
don't forget to change permission of bpp file aftr edit to 0755 rwx-r-x-r-x :)

and aftr that reboot to take effect:)
[LG Optimus 2x] spica1234:

[LG Optimus 2x] pgmunzi:
Hi, with rc11-r the second cpu never goes sleep and i have 60mA of battery consuming, with rc11 i have only 2mA of battery usage

Inviato dal mio LG-P990 usando Tapatalk
[LG Optimus 2x] ilos:
how did you see that ?
[LG Optimus 2x] spica1234:
It goes off when the task load drops:)

it suspends in notime and activates in no time. So when you check it it quickly activatesand when you observs w/o doing any activity it quickly suspends.

When you watch through system tuner pro click on system instead of cpu now wait for some seconnds than click on cpu and you'll find 2nd core off:)

V20l with rc11, 26 hours of battery life from 90%-18% and system uptime of 35 uptime with no locks or crashes so far, starting to look like I will stick with this for a while :-)

Thanks for that Spica!
[LG Optimus 2x] spica1234:
Welcome :)
[LG Optimus 2x] kosi2801:
Followed these instructions word by word (used rebuilt V20o ROM), but init.d is still not working :(

I know, this thread is not directly related to this problem but I'm pretty much out of ideas what I could try further. What puzzles me more is, that the used ROM itself already states, that init.d should be enabled :confused: Yet, no sign of anything being executed in init.d and no swap visible via 'free -m '. Setting it up manually works, but not automatically during startup.

Searches in the forum also did not turn up anything useful for me. Has anyone some more hints for me, how I could enable processing of init.d?
[LG Optimus 2x] markop90:
Huge difference between rc 11 and 11-r...phone is much more fast and reactive! Maybe because of reverting to compcache! Thank you Spica!
[LG Optimus 2x] spica1234:
Welcome yes compcache and because of my modification for 2nd core cpufreq scaling support sync with 1st core:)
[LG Optimus 2x] K Dotty:
I tried to flash this on my friends phone and now when the phone boots, an lg logo appears with a blue loading bar beneath it. The bar freezes, reboots and the process happens again. I hav no experience with LGs at all so im not sure what went wrong.

Its running stock froyo and the latest recovery available in Rom Manager

Any suggestions?
[LG Optimus 2x] spica1234:
Sorry for that but kernel since rc8 is not compatible with froyo. Download SR1/2 versions from 1st page :) that will solve the issue:)
[LG Optimus 2x] K Dotty:
I flashed it and wiped dalvik cache but i still have the same problem :confused:

If i flashed a stock gb rom - rebooted- then flash the kernel, will that work?
[LG Optimus 2x] wapz:
Which stock rom, v20l? How did you flash it?
[LG Optimus 2x] wapz:
But rc11r is so fast i already see both at 1.0ghz when i click the cpu tab, and they go back to 300mhz directly after :-)

Also, I always believed Tegra2 is unable by hardware to scale frequencies on both cpu's independently from each other, e.g., one cpu at 300mhz and one at 600, does that also mean that also one cpu shouldn't be able to be disabled?

If it was, why would nVidia not have enabled it by default? That wouldn't make any sense, right?
[LG Optimus 2x] abwyatt:
Perfect!!!!! :D
[LG Optimus 2x] Striatum_bdr:
Works very good indeed, even my bug concerning toggle between data and wifi seems gone.

Great!
[LG Optimus 2x] martinesko36:
Hey Spica, great work. I have got an issue with rc11-r and PP9 - when i first installed the kernel and rebooted, the phone was pretty smooth. I OC to 1.4ghz and tried to swipe in the folders of Go Launcher EX - really smooth, never before happened, no lag(that was the only place where it was laggy). Then i installed PP9, and then reinstalled RC11-R and OC to 1.4GHZ and swiping between apps in folders, was not so smooth like without PP9.

And scrolling is the same on 1ghz and 1.4 ghz - before when i overclocked i can see the difference, but now no. If you can't think of something, then please tell me how to remove PP9. Thanks.
[LG Optimus 2x] sephiroth76:
Thanks spica for the new kernel.

Installed RC11-R without PP9 and so far so good but the response of script manager and root explorer seems to be slower than before...oh..and one more things...the cache file seems to be EXT4,it's that normal?
[LG Optimus 2x] wapz:
Here as well.
[LG Optimus 2x] McGiverGim:
Thanks Spica for your hard work. Istalled R11-R over v20o and all seems working ok (including swap).

Regards!
[LG Optimus 2x] Dzhedaj:
Finally some usable kernel after SR2 :)

The phone really feels snappier and with less slowdowns. It shows very obviously in Market, it's never been so fast.

Thanks spica!
[LG Optimus 2x] spica1234:
Welcome. Now with RC11-R , if you want to install PP then first install PP and then RC11-R.

Yes i should have named it SR3 during my initial testing because it was rock stable but my standard for SR releases are very high that's why we have only 2 SR versions till now:)

Actually I've worked very hard for RC11-R only 3 hours but mainly worked on stability ,2nd core performance w/o affecting battery and optimized PMU(Power Management Unit)

Now you can see real difference in dual-core in responsiveness and performance along with lowest standby battery consumption (~1-2 mA)

Actually in previous stock cpu drivers 2nd core was activating very late and 2nd core was forgetting its min and max freq thus failing to scaling in sync with 1st core and thus prematurely it was being off in realtime workload needs:) That's why i modified cpufreq driver so that 2nd core remembers its min and max freq independantly and sync when 1st cpu changes. It quickly sync with1st core during work-load and quickly suspends when task load drops. I've took special care that this behaviour improves battery life instead of drainage:)
[LG Optimus 2x] Stefan Gündhör:
Perfect timing for a good kernel, will be integrated in my gueste2x v2.2 final :) Thx!
[LG Optimus 2x] Dzhedaj:
So what does PP do in addition to RC11-R kernel?

Any advantages of using/not using PP?
[LG Optimus 2x] Ferrum Master:
Spica, I still didn't understand the stuff behind 48bits... why it works? Does it work like a post filter in frame buffer(just like Bravia does on TV's with their powerful xilinx cpu or on Xperia phones), but the the memory footprint should not increase, just cpu power is used I dunno how GPU is affected here tough if the rendering is done by it.

There is a definetly some sort of like FRC filter trick as used on modern cheap panels... ain't it?
[LG Optimus 2x] spica1234:
Yes Kernel is a basic core package and PP works on RamDisk. It modifies ramdisk and tunes it for performance of hp kernel:)

Ramdisk+Kernel = Boot.img through which phone boots and operates:)
[LG Optimus 2x] Dzhedaj:
So PP should not be used together with Supercharger?
[LG Optimus 2x] alktlr:
It would be nice with a giveMeRC11R_only.zip for v2.1 while we patiently waits for v2.2 final :)
[LG Optimus 2x] carburano:
Great work spica... Django is flying with rc11r

Inviato con il P990 DjangoManouche!
[LG Optimus 2x] spica1234:
Alright as you've seen on pc/laptop 8bit/16bit/32bit.

Colors are combinations of offset of RGB(RED GREEN AND BLUE) colors.

16Bit=256k colors(mixture of 256RGB offsetted colors)

24Bit=16 Millions colors (mixture of 16Millions RGB offsetted colors)

alright now how it works:

Our nVidia kernel tegra framebuffer graphic driver can support upto 128bits. What we change is that bits_per_pixel tegra framebuffer. OS/System(Android) supports 24BPP and LCD Controllers (our LCD) supports 18bits. So when we use 16 bits per pixel 2bits of lcd controllers are not being used only 16bit instead of lcd pannels capacity 18 bit.

So how come 32bits works. When we set tegra fb bits per pixel 32bits. Kernel sets it to 32bits. OS resample its matrix in downsampling of 24 bits and lcd controls downsampling it by matrix in 18bit.

More simple example.

Suppose sound card supports 44khz output. Now suppose you're watching movie in a software as an xample powwerdvd which output its stream in 92khz. And media example cd of movie yourewatching is in 48 khz. So how it works. Powerdvd resample 48khz dvd media content in 92khz doing upsampling matrix. And sound card converts 92khz to hw default 44khz by downsampling matrix. But you obviously notice the difference:)

So inshort to notice more colors/saturation/vividness you need content which has more colors/definitions. Like HD images/HD videos:)
[LG Optimus 2x] spica1234:
Welcome bro:)
[LG Optimus 2x] spica1234:
You can use it. But you may not notice what performance effects come from what. First try using w/o it then use with charger and to judge from both/from one you're getting performance and battery. If combination is giving good performance then use it:) I've not tried anything except pp and hp so i have no experience:). PP is specially optimized for HP krnls:)
[LG Optimus 2x] spica1234:
Yes.

Follow these steps:

-Install stock ROM

-Install HP PerformancePack V9 ,right after it

-Install Horse Power Kernel RC11-R, right after PerformancePack

-Reboot, you're now ready for successful boot:)
[LG Optimus 2x] Ferrum Master:
Spica, you remembered me of my old pain with Audigy 2 ZS, it converted everything 44.1->48khz at its hardware codecs, and sounded like crap :D. Auch...

So we are talking about dithering methods. FRC cheats itself by switching between two closest colors in supported 18bit color map of the panel to image full 24bit+ color scale... I suppose it must be the same method, otherwise we couldn't produce more colors on LCD as it is possible by our given color address space ie 6bit per channel. I dunno how our panel works. Its firmware isn't accessible. I suppose someone has a datasheet also for it?

So setting up the bit depth in OS, sets less aggressive dithering from the original source, so more color space data is being set to the panel controller, witch does it tasks further... I hope I did get the right idea...

[LG Optimus 2x] wapz:
Just had my first hang, it locked up for 10 seconds and rebooted directly afterwards. Hypnos v1.0 (v20m based) with matching baseband.
[LG Optimus 2x] Kenks:

[LG Optimus 2x] abwyatt:
Try Hypnos v2.0 SR1. No locks or reboots here.

I did have occasional locks with UV of 50 mV especially with Hypnos v1.0. Hypnos v2.0 has been more stable for me with HP. Have been running with UV of 25 mV and OCed to 1.2 GHz for my everyday ROM with no locks or reboots. Will try to push it again to UV 50 mV soon :D
[LG Optimus 2x] markop90:
changes are on display, not on photos
[LG Optimus 2x] abwyatt:
I am consistently getting about 22 mA in idle which is reasonable I think for my location. I always think the 2 mA reading is spurious. The only time I ever see it is after disconnecting from the charger and it seems to get 'stuck' there for awhile. Not sure if that is to do with Battery Monitor Widget that I use or the kernels, but I have observed that with every different GB ROM/kernel that I have tried.

Keep in mind that battery usage/drain is always subject to lots of variables which makes any comparison between phones and locations questionable. For example, distance to mobile cell towers plays a big role on determining power drain. We can observe this objectively by measuring the mA drain when traveling to different locations while keeping everything else constant. I often see big differences between the locations that I travel to. The only thing that we can really do is compare our own before and after situations from the same location.
