[DEVs only] EXT4 system/data/cache partition for x10 - XPERIA X10 Android Development

I have been going through many things ,
REQUIRES UNLOCKED BOOTLOADER
And finally made this ,
This is a flash able zip which requires cwm4 recovery and a rom which supports ext4 partition after that
Otherwise the partition gets removed
Since we don't have many roms with Ext4
I'll just include this zip
I just heard someone wanted a good dev who would make something good , other than barebones

This should be interesting . Apparently EXT4 provides a significant boost in speed right?

---

Quick question. With a rooted X10 I can format system/data/cache anytime I want to install a new ROM. So my question is....why cannot (with a locked bootloader) format it to ext4? Is there something stopping the filesystem from booting when formatted in ext4?
The reason I ask is other devices can do this with only a rooted device and no BL unlock.
EDIT: and yes it is supposed to provide a boost in OS speed. Mainly in multicore phones but should help with ours as well.

Yeaah it does It would be great if we could get this working on our phones...

EXT3 and EXT4 both are journaling FS. That's where the speed came in. It doesn't boost the OS but it made the storage performance better. Thus resulting in a faster system.

Good show! My current phone is ext4 now and it definitely does boost speed
Awesome work

---

Yes but whatever the reasons you have, never do this on your SD card as it will result in memory wear.
Anyways, nice job here spaarc.

This would never really work correctly right now
This needs to be included in the original updater-script as well

---

the sdcard needs to be of a higher class (class 6 and above) to actually gain some performance benefits.... else it will all lag..
btw we can get multiboot based on this...
EDIT:
based on the update.zip u posted...
Code:
ui_print("-Formatting Data");
format("ext4", "EMMC", "/dev/block/mmcblk0p26");
ui_print("-Formatting System");
format("ext4", "EMMC", "/dev/block/mmcblk0p25");
ui_print("-Writing System");
mount("ext4", "EMMC", "/dev/block/mmcblk0p25", "/system");
package_extract_dir("system", "/system");
show_progress(0.400000, 0);
ui_print("-Formatting Cache");
assert(unmount("/cache"), ui_print("/cache unmounted"));
format("ext4", "EMMC", "/dev/block/mmcblk0p27");
u do realize that ppl dont have 25+ partitions on SDCARD right?
also the init.rc files will have to be changed... cause the init*.rc files mount the /system /data & /cache as MTD

That's why I had to write "Devs only"
But every one comes in
This is still alpha and needs to be corrected

Can you start converting your ROM to updater-script and update-binary
Can u get CWM4 Recovery running ?
That would allow to run it right now

yes i can
wait we need to get a few things ready before...
here is wht we need:
1) willing testers, who are ready to repartition SDCARD (may render SDCARD unusable later on!!!!)
2) a CLEAN ROM (no tweaks/etc) [we can add them later]
3) ramdisk which we will use (i can help out with that)
4) bootmenu (i already have most of it ready)

likewise - as said before i have a sacrificial card, but it's a good c6, so perhaps when you need a higher class card tested let me know!!
