[KERNEL][Z1] [5.0-5.1][F2FS]Advanced-Kernel v19.0[03/26/2017]

[olokos]

@sharonliu just changed all partitions on the phone to F2FS including /system and it won't go past the kernel bootlogo :/ Went back to ext4 for /system
PS Are you going to include MultiROM TWRP at last?

 

[lavenbut]

How can i enable lz4 algorithm

Post 73 he only mentions data and cache partition support, so probably not system too [emoji14]

True, but it shouldn't be that hard to also get it to work on /system, I think.

Z2's MultiROM TWRP at last or venkat kamesh's are not working. When reboot into Second ROM, cause of the bootloop.
I modified stock fstab(data and cache) to f2fs using cm12.1 fstab. Does anybody know how to edit fstab System File?
Below is v14 fstab mount flag.

V14's zram is lzo as default. If zram works fine and stable, v15 will set lz4 as default.

V14's zram is lzo as default. If zram works fine and stable, v15 will set lz4 as default.

I don't know it too, but I would try this:

Anyway I read that it's useless to use f2fs for system (it's faster only when files are changing, reading the same files is a bit faster on ext4).

I have some random reboot with v14. No problems with v13

Everything seems to be fine with me. Has anyone here had the same issue ? If the kernel crashed (freeze and rebooted),
please fetch last_kmsg file after the crash reboot and post in the thread.

su -c cat /proc/last_kmsg > /sdcard/last_kmsg

 

[phhuang]

I got reboot issue on v13 but much stable with v14

 

[lavenbut]

No reboot, no issues, waiting next version for lz4

 

[olokos]

@sharonliu just sent you a PM with last_klog after one of reboots and I had about 5 of them just today, no idea why.
TWRP doesn't have anything to do with booting roms AFAIK, so could you please release or PM me v14 kernel with MultiROM TWRP? I tried to build it myself, but failed terribly and wasted tons of time.
Thanks.

 

[sharonliu]

to be included in v15.0 changeLog:

it will be released soon

v15.0 changeLog:

Waitting u upload file. Excited

 

[SuperLamic]

@sharonliu didn't you forget to upload v15 for Z1 (not compact, compact is there)?

 

[hitesh1792]

I guess the upload may have failed and he did'nt notice that and after that went to sleep! ..dude wake up we need the update! ..

[hitesh1792]

@sharonliu can you suggest me tempreature setting for the 3phase msm_thermal u added in the v.15 or i should leave it the default setting as it is?
