Booted your kernel and noticed the lack of the the 77sdcardspeedfix in init.d. I was just wonder if this is not needed in you kernels?

LOL my bad I was asking if Netflix will work right out the box with this room or do I need to change the prop build... and I don't know how I missed the full question...

Sent from my LG-P999 using XDA Premium App

You will need to download my AOSP ROM... the netflix update is not part of the kernel, it is a fix to libstagefreight which is part of the ROM framework.

However, because netflix was never optimized for this device, I have heard from users saying that netflix will playback at a faster pace than normal, so it's like watching with fast forward on.... Try my rom and try netflix for yourself and see if you can live with the current limitation or not....

faux can you release a ext4 version of your kernal since the CWM have been updated to support ext4 roms backup and recovery?

so basically we cant backup a rom with an ext4 kernel n then say cm for instance flash a new nightly over it? cuz thats what i did just seeing how recovery would handle it but i also got stuck on lg splash screen but this is what i did when i was in cm i hit power and u know how it gives u power down or reboot or reboot into recovery i did it that way n restored a backup n thats when i got stuck so i pulled batt went into recovery got another backup well basically il make this short i instead hit power and powerd down.. instead of going into recovery that way i went in with power down n vol down n everything worked ext4 backup was good so u mite want to try going into recovery that way worked for me

No, stock CM7. However, I just tried the Trinity kernel and I got the LG logo for a couple seconds and then the phone shuts down with that one.

I've been having the exact same problem. No clue why its doing it. Posted over in the Trinity kernel thread, but nothing has worked so far. Got a suggestion that it might be a hardware defect in the memory, but i'm really hoping thats not the case.

    Here's a kernel build based on CM7 Kernel Source Tree

    Special Shout out to DebauchedSloth for his pull requests and collaboration on this open source project

    Just a statement regarding kernel source: The Kernel Source is of course covered under GPL version 2. Free software does NOT mean no work or time was spent working on it. I have donated a large sum of my free time to hack this kernel. If you use my modified kernel source in its entirety, I kindly ask you to send me a github pull request or PM whenever you find bugs or think you can help improve my kernel hack further. This way the entire community will truly benefit from the spirit of open source. Thank you :cool:

    What is a Kernel? The Kernel is the Foundation in which everything else builds upon in any software system.
    [Car Analogy]: Kernel is like the Engine, Electrical system and the Transmission to a car. The Library, Framework and the Apps [AKA ROM] are the body frame and the rest of the Car.


    ​


    THIS KERNEL is BASED ON CM7 Source Code. So it is COMPATIBLE ONLY WITH CM7 Builds.

    Please DO NOT use any task killers, they DO NOT improve performance nor battery life. They INTERFERE with your phone's stability (more crashes) and App compatibilities (Forced Close).

    ZRAM (aka CompCache aka RAMZSwap)

    ZRAM is an updated version formally known as CompCache and RAMZSwap. It was originally designed for 2.6.38.xx kernels, I have backported to our 2.6.35.xx kernel. ZRAM allows real-time compression of memory objects in RAM thus reducing memory pressure for the Linux kernel and can keep more apps in memory longer (more apps in RAM == better performance, less fetching from slower MMC or SDCard). Compression, however, is not Free. Some CPU cycles are required to do the compress/decompression, so there's a slight penalty for it. The original CompCache / RAMZSwap required a user space binary to control its behavior which adds additional penalty to performance, but the new version ZRAM eliminated the need for a separate dedicated daemon, thus reducing the overhead and increased performance from the old CompCache by 20%. Therefore, with the newer implementation of ZRAM interface, the performance penalty is almost negligible. :D

    Joe's RCU (Optimized for Small SMP systems)

    Joe Korty has created an RCU for small SMP systems (> 32 cores). His approach is to isolate all the Garbage Collection (GC, a slow time consuming but necessary processing) to a single core, thus allowing other cores to ONLY work on real required processing. This will allow the additional cores to complete their assigned tasks as fast as possible (not bogged down by GC) then immediately go back to a suspended state (saving battery).

    Fast No Hz RCU (Optimized for SMP operations)

    Fast NoHz is an optimized version of the traditional Tree RCU. Many new kernels are using the Tickless NoHz design. This RCU is tailored and designed to work with the new NoHz kernel system.

    Brain F*ck Scheduler - (BFS)

    This scheduler is designed to be simple and speedy tailor specifically for user interface type systems such as desktop/smart phone devices where user interaction is MORE important than serving 1 million web requests (CFS, the default scheduler) at the same time (think of nimble desktop workstations vs large corporate servers).

    SLQB - (SLAB allocator with Queue)

    This memory allocator is designed for small number of CPUs system (such as desktop or smart phone devices). This allocator is design to be simple and it is optimized for using order-0 pages as much as possible (order-0 pages are the simplest therefore quickest type of memory in a Linux system to allocate). Not all kernels are using SLQB including CM7 main line...

    Fair Budget Queue (BFQ I/O scheduler)

    This I/O scheduler is an improvement on top of Completely Fair Queue (CFQ). CFQ is fair in terms of time but not in terms of throughput / bandwidth, so BFQ make sure that both time and throughput / bandwidth are balanced across all requests.

    THIS IS ONLY FOR THOSE WHO ARE WILLING to FLASH THIS ON HIS/HER OWN PHONE... IF YOU ARE NOT COMFORTABLE WITH THIS YOU SHOULD NOT FLASH THIS.

    For those who decide to flash, please post the results and/or issues here :D
