upstream-f2fs-stable-linux-4.14.ymerged
QCACLD-3.0+ Audio-kernel + Data-kernel
Sultan’s SimpleLMK as the default lmk.
Selectively picked Sultan’s patches
Power usage optimizations
Memory management optimizations
Network stack optimizations
Scheduler optimizations
Optimized CPU freq table and energy model for improved battery life
RMNET extensions ported for improved network perf
UFS fixes ported from google
Latest exfat driver merged
Compiled with GCC 13 with DCE enabled
Using zswap + vbswap to replace zram:
- Backported z3fold memory allocator
- Backported zswap changes from mainline
- Samsung zswap hacks forwardported
- Backported z3fold memory allocator
MGLRU Backported from mainline
TL;DR:According to Google’s fleetwide profiling, multi-generational LRU yields an “overall 40% decrease in kswapd [the kernel daemon that manages virtual memory] CPU usage,” an “85% decrease in the number of low-memory kills at the 75th percentile,” and an “18% decrease in app launch times at the 50th percentile.”

FUSE_PASSTHROUGHfor now
- Selectively pick sultan’s changes to kswapd
- Pick sultan’s fixes to vmpressure
[1]:
We have already affined kswapd’s kthreads to the little cluster and since our little cluster has 6 cores, I thought it would be better for each core to have its own thread.

R1:
- Initial build
/ Notice /
- This kernel is an interactivity focused one, which
implies that I am ready to sacrifice some throughput
for improved latency. - This kernel is not meant to be customized by the user.
- Check your fingerprint sensor version before flashing the kernel.
- Device info hw app -> Fingerprint: if it shows FPC then flash
FPC,
- if it shows something else then flash CPO.
- Device info hw app -> Fingerprint: if it shows FPC then flash
FPC,
- Flash correct build according to your fp sensor.
/ Flashing instructions /
- Reboot to recovery
- Flash the the correct kernel build
- Enjoy
