[KERNEL][03/13/2022] fsociety tribute for Google Pixel 4a [A11-A12/L]

[momojuro]

Hello friends,

New update is up! Thanks to my Telegram testers for their useful feedback and reports.

Changelog

fsociety tribute stable#1.90

Thanks to everyone involved in the following changes:

• Android 12 official support with stock A12 kernel changes
• Merge branch android-msm-sunfish-4.14-android11-qpr3 (July 2021 security patch - thanks to engstk)
• Makefile: Prohibit VLA *
• proc: cmdline: Patch SafetyNet flags (The device passes bootloader SafetyNet check - thanks to sultanxda & kdrag0n)
• PM: sleep: Don't allow s2idle to be used (enforce the default deep sleep mode because s2idle is buggy - thanks to sultanxda)
• clk: qcom: gpucc-sdmmagpie: Undervolt the GPU (thanks to lybxlpsv on Github)
• Revert "defconfig: Enable the BPF JIT compiler" (to fix gaming lag issues) **
• Revert "rcu: Speed up calling of RCU tasks callbacks" (it caused kernel panics)
• Revert "qcacmn: Disable all of qdf_trace when WLAN_DEBUG is disabled"
• Revert "mm: wakeup kswapd for order-0 allocation"
• VFS: use synchronize_rcu_expedited() in namespace_unlock() (statiscally faster filesystem unmounting time)
• qcacld-3.0: Fix regulatory domain country names. (thanks to kdrag0n)
• sched: fair: Tune scheduler capacity margins for sm7150-ab (thanks to KenHV on Github)
• sched/fair: Revert Google's capacity margin hacks (they aren't needed anymore - thanks to sultanxda)
• sched/fair: Allow load bigger task load balance when nr_running is 2
• sched/fair: Optimize test_idle_cores() for !SMT
• sched/fair: Fix unnecessary increase of balance interval
• sched/fair: Trigger asym_packing during idle load balance
• sched/fair: Fix rounding bug for asym packing
• sched/core: Optimize try_to_wake_up() for local wakeups
• sched/core: Fix preempt warning in ttwu
• soc: qcom: watchdog_v2: Fix memory leaks when memory_dump_v2 isn't built (thanks to sultanxda)
• soc: qcom: Remove tracing (thanks to celtare21 on Github)
• UPSTREAM: psi: eliminate kthread_worker from psi trigger scheduling mechanism
• BACKPORT: cgroup: make per-cgroup pressure stall tracking configurable
• arm64/dts: sdmmagpie: Disable per cgroup tracking via psi (for less system overhead and better performance - thanks to Freak07)

* This Linux upstream change makes the kernel more secure and less bloated code wise.

** Enabling the BPJ JIT compiler was supposed to bring better performance, but it had the opposite effect for some games.

In addition to kernel support, what else I would need to mount a samsung t7 formatted with exfat?

Check out this reddit post I found discussing that. The last option they tried out seemed to do the trick.
Good luck! It's the best I can do.

Nothing works out, closest is Paragon software in play store, can browse but cannot play anything.
What exactly does this do in kernel notes?

• exFAT filesystem support

The exFAT drivers are built-in the kernel, but the partition mounting isn't being done by the ROM.

ohh? so frankly just need figure out fsck to mount it right? but that would mean editing system partition right? So in other words a magisk addon would been needed. It ok tho, simple solution is format my drive to fat32.Seems to be working between pc and phone so far.

The easiest and seamless solution would be to format the drive to FAT32 indeed!

I did also come across this
[MOD] EXT4/EXFAT/NTFS support for stock Pie on Pixel 2 (XL) | XDA Forums (xda-developers.com)

mentioned about needing sultanxda kernel, and also about custom magisk? not sure but closest thing to magisk module I seen.

When I was looking for clues to solve your issue, I found that there were workarounds like this one, but only for Android 8.0/9.0. I wouldn't recommend you to try this method on your Pixel 4a.

So how do I install the a12 version without a custom recovery?

So how do I install the a12 version without a custom recovery?

You can install the kernel with a kernel manager/flasher like FKM (Franco Kernel Manager) on A11 and A12.

Speaking of which, #1.99 is coming out this weekend after a month of work with my testers on Telegram!

 

[momojuro]

Hello friends,

Here is today's new update! I would like to thank everyone involved in the following changes, and to my testers from the Telegram group.
There were no security patches for A11, but they were instead for A12 beta 5.

Changelog

• treewide: Silence more verbose logging
• Under-the-hood scheduler improvements
• Memory management updates
• Implement arter97's changes to the msm serial driver which fix a possible runtime power management malfunction
• cpufreq: schedutil: Don't set next_freq to UINT_MAX.

There is a kernel out there for android 10 that supports ttl spoofing?

@momojuro
Thanks for the kernel. Can you please enable the DisplayPort function?

The source code is posted, why don't you build your own kernel with features you deem necessary?
