[ROM] [ZTE Z7MAX] [Android 5.1.1] CM 12.1 unofficial

[securecrt]

zram is already present in codeaurora kernel, I added the lz4 support (for better compress/uncompress speed) and enabled

The zram code has a lot of upgrade after kernel 3.4, in the codeaurora the code for the MSM89X4 TAG is stopped at 2013-11-20.

The TAG list

But the zram driver has been upgrade much since it has been promoted out of staging. more stable I think. If you can backport that part I think we can get better porformance and gain more stablity while using the zram in the next release.

so far I have tested the zram kernel for several hours now, it looks fine, no reboot or crash issues.

Thanks Paolo! Your last firmware is very stable!
Can you add to firmware auto call recording, the same as in YIOS?

if you want to try the kernel with zram support download and flash this zip (without wipe)

cm12.1_zramkernel.zip
zram is disabled by default but you can enable with trickster mod app

after 24 hours running, the zram kernel looks good, no problem has been found until now.

I added a file to enable the zram : /system/etc/init.d/65zram

#!/system/bin/sh
#
