GearLock-Package [xanmod][zen-kernel][GoogleLTS][codename:sakura] Kernel 5.4.x for Android-x86 5.4.140

The scheduler is a topic of keen interest for the desktop user; the scheduling algorithm partially determines the responsiveness of the Linux desktop as a whole. Con Kolivas maintains a series of scheduler patch sets that he has tuned considerably over the years for his own use, focusing primarily on latency reduction for a better desktop experience. In early October 2016, Kolivas updated the design of his popular desktop scheduler patch set, which he renamed MuQSS. It is an update (and a name change) from his previous scheduler, BFS, and it is designed to address scalability concerns that BFS had with an increasing number of CPUs.

The ONLY option you are likely to need is "ant_sel". The penny-pinchers at some laptop vendors,

mostly HP, decided to save a few cents to install only one antenna. That would not have been a

problem as the driver contains the logic necessary to handle this case; however, the idiots

failed to correrctly encode that information in the devices ROM. Accordingly, the driver follow

the ROM setting and uses the WRONG antenna. Effectively, the device has NO usable antennas.

Can you add EXTMOD=realtek to your grub bootloader ?
It's not missing, it just that there is some problem......

Click to expand...

• Upstream Kernel to 5.4.30 (which fix Realtek Ethernet problem)
• Change fom TCP Cubic to TCP BBR Congestion Control
• Turn on Preemptible tree-based hierarchical RCU
• Turn on Budget Fair Queue (BFQ I/O sheduler) as default.
  (And a little change accord to zen-kernel)

Because there are many positive reports about xanmod Kernel in 5.6 so I decide to use it in the 5.4 branch

Click to expand...

• Upstream to 5.4.32 (need commit 3fcd53b1d859799686a08785afb8990566c31cfa to fix Ethernet).
• BBR TCP Congestion Control + CAKE Queue Management Algorithm is now default without using sysctl.

I. Introduction and Features
This kernel........... is like a trial since there's a lot of thing need to be done. I made this kernel with hoping that more hardware can be supported in Darkmatter. Hope that you guys can run this kernel and have the best experience you got

Some small features :
- Based on Mauro Rossi's kernel-5.4_si_ylng branch
- Added zen patches from zen-kernel (MuQSS CPU Scheduler compile on non GoogleLTS version) (depricated)
- Added xanmod patches starting from 1.2.1 (https://xanmod.org/)
- Added support for Realtek rtl8723de wireless chipset with ant_sel=2 (read Troubleshoot part for more info)
- Added Realtek rtl8821ce support wireless chipset support.
- Replace stock r8188e wifi module with another module from aircrack-ng

** Some info about MuQSS (Multiple Queue Skiplist Scheduler)

Source :https://lwn.net/Articles/720227/
WARNING : Please do not use it if you have problem with CPU (like TSC_DEADLINE) or else it may got CPU bug, use GoolgeLTS version instead. (temporary deprecated)

Update : Starting from version 1.2.1 I will switch to xanmod patches, read more about it https://xanmod.org/

II. Download
Up there

III. Troubleshoot
1. As lwfinger stated that :



So try this method can help you not only change antenna in rtl8723de, but also some Realtek wifi card like rtl8723be
Open terminal and type this :
Bash:
su (if you use Terminal Emulator or Termux) rmmod <your_wifi_card> modprobe <your_wifi_card> ant_sel=<antenna_number> <your_wifi_card> is your wifi card name, like rtl8723de <antenna_number> there are 3 number you can use : 0, 1 or 2
IV. Changelog :
- v1.0 (28/03/2020)
+ Initial Release.

V. Bugs :
- Not all device is supported, even if it listed in the kernel..........
