Great kernel, but as in ver 3.3 cpu hotplugging didnt work in last slimkat. If i use zzmoove, it disables one core but didnt ever reach more than 800mhz, even with running benchmark in background. If using other governor cpu goes to max, but both cores stay online all the time. Maybe it has something to do with rom, but with nextkernel all running fine. I remember it runs with agni kernel 3.3 too, but after i tested some other kernel and switched back (or maybe with a newer rom upgrade...didnt see that as fast) no correct hotplug anymore.idea? thx.

[Galaxy Tab 2 7" Android Development] iroshan:
Just want to clarify. When I flash modified twrp will it always format as f2fs? Even when tosuing nightlies? Or do I have to format system using your tool? Thanks. Can't wait to try this.
[Galaxy Tab 2 7" Android Development] psndna88:
if before formatting it was ext4, it will format to ext4 only

if before formatting it was f2fs, it will format to f2fs only

so u need to use formatter tools as required to break the trend ;)

[Galaxy Tab 2 7" Android Development] iroshan:
I think I managed to convert to f2fs.:)

First I flashed modified twrp.

Then all the formatter zips.

Then omnirom zip.

Next was gapps_core.

Then agni kernel.

Then supersu zip.

Then titanium flashble zip.

Then I fixed permissions.

I was able boot and now restoring backups.

Any way to find out the file system on each partition?

I didn't modified the updater binary.
[Galaxy Tab 2 7" Android Development] psndna88:
good ;)

terminal command:

su

mount | grep f2fs

if u didnt modify the updater-script and not put # before format line and unmount first system unmount line, ur /system is still ext4.

[Galaxy Tab 2 7" Android Development] iroshan:
This is the result. Cache and preload is f2fs. Yea...:P

root@espressorf:/ # mount | grep f2fs

/dev/block/platform/omap/omap_hsmmc.1/by-name/CACHE /cache f2fs rw,seclabel,nosuid,nodev,noatime,nodiratime,background_gc=off,user_xattr,active_logs=6 0 0

Well .I will format system again and flash the Rom.

# before format and unmount. :) simple enough.
[Galaxy Tab 2 7" Android Development] psndna88:
dont forget to Mount system and data in twrp manually before any zip flash thats because those updater scripts do not use the correct universal Mounting commands for system or data as we had only ext4 support before

this command should be used in updater-script to mount system

run_program("/sbin/busybox", "mount", "/system");

INSTEAD OF

mount("ext4", "EMMC", "/dev/block/mmcblk0p9", "/system");

Does f2fs increase system performance??
[Galaxy Tab 2 7" Android Development] nihilista:
Tested again, but again no hotplug with interactive governor, zzmoove did hotplug but stays between 180-600 while benchmarking....never reaches 1200mhz (wgat i set as max).

Edit: Watched with cpuspy, with zzmoove seems ok, but no oc possible, with some other governors no hotplug, with hotplug governor hotplugging and oc seems to work.
[Galaxy Tab 2 7" Android Development] psndna88:
it does increase write speed significantly, and snappiness is seen.

what i have experienced by formating my internal storage to f2fs is that previously when copying large files (>4gb) with usb mtp, almost always transfer stopped and error shown was "device has stopped" or somwthing like that , now after clean format its fine.

interactive gov doesn't have hotplugging support from begining !!

zzmoove has some scaling up issues and i have mentioned it to one of the devs contributing to it.

hotplug governor seems to work well untill it freezes the device and reboots.

I know, but normally if you set a non-hotplugging governor kernel did it for itself. Used next kernel for a long time and it did. Hotplug governor never has problems on next kernel, on your kernel i got one reboot, but after that it rusn fine till now.

Edit2: Ok, forgot to install latest slimkernel before upgrading, so now internal sd is back....and rngd now works...so command back ;)
[Galaxy Tab 2 7" Android Development] jazzespresso:
thank you for respond. if you check [ROM][Official][4.4.2] SlimKat Stable 3.0 thread, they dont suggest any custom kernel, so it is up in the air, that's why I asked here what we can use, just to be safe side..
[Galaxy Tab 2 7" Android Development] psndna88:
This is safe as it retains its original prior flashed kernel's files and only modifies them as needed for AGNi kernel functioning.

so this relieves me from updating the ramfs for every rom's changes

but had to make lot of effort initially.

just that user needs to flash directly over the rom so that the rom's kernel is modified (trouble free)
