==== AUFS Kernel only for Porteus ====

Can you add this to the next kernel build

Code: Select all

CONFIG_BTRFS_FS=y
CONFIG_DRM_VBOXVIDEO=m
CONFIG_VBOXGUEST=m

I am using Btrfs for the "changes" persistent.

Thanks.

1. AUFS patch for kernel 5.12-rc2 is not yet ready.
aufs5-standalone.git/include/uapi/linux/aufs_type.h:#define AUFS_VERSION "5.x-rcN-20210222"

(1)tmpfs-idr.patch patching is error.
(2)fs/aufs/vfsub.h is syntax errors at compile.

Note
You can build kernel 5.12-rc2 without AUFS patch and then get OVERLAYFS kernel.


2. The config was updated.

Now AUFS patch full set is ready for kernel 5.11.5.

Thanks.

Kernel 5.11.6

A 5.0 desktop file invoking firefox 86.0.1 with a url results in firefox opening with no open tab.

Added in 15 minutes 12 seconds:
The 5.0 desktop file invoking firefox 86.0.1 with a url works with kernel 5.11.0.

Porteus 5.0 rc2 Xfce

Using kernel 5.11.6 I am unable to compile the ntfs3 driver (requires glibc 2.33) and after upgrading to glibc 2.33 the compilation is successful but 'ntfs3.ko'module cannot be loaded.

Code: Select all

# insmod ntfs3.ko
insmod: ERROR: could not insert module ntfs3.ko: Operation not permitted

Are you using glibc-2.33 to build Kernel 5.11.6?

Using kernel 5.10.5 everything works fine Porteus Kernel Builder (Post by Blaze #80931)

You can try it https://drive.google.com/uc?export=down ... oKDAb2Roo8

Thanks.

And today it works.

Hey, guys, have you tried to build the kernel without the CPU mitigations just to see how much we can improve performance? Here's how: https://linuxreviews.org/HOWTO_make_Lin ... Intel_CPUs

And here are some benchmarks: https://www.phoronix.com/scan.php?page= ... wn-2&num=2

Hey, guys, have you tried to build the kernel without the CPU mitigations just to see how much we can improve performance? Here's how:

my reading of that link is that it's not about building the kernel without mitigations, but simply turning them off using kernel parameters (ie. what we call around here: "cheatcodes") on the boot line..

[fulalas]

You're right! So basically (I'm not on Porteus at the moment):

1- sudo echo 'mitigations=off' >> /etc/sysconfig/grub
2- sudo grub2-mkconfig -o grub.cfg
3- copy this new file to [bootDevice]/boot/grub/grub.cfg (or [bootDevice]/boot/grub2/grub.cfg)
4- reboot

EDIT: nevermind, I'm too busy to pay attention So... Can we edit porteus.cfg and include 'mitigations=off' in one of the APPEND menu entries?

[ncmprhnsbl]

So basically

quite possibly ..(i havn't messed with grub for many years)
or this: https://www.howtoforge.com/tutorial/ker ... eter-edit/ to simply edit the boot line at bootup (e for edit> add parameter to 'linux' line > ctl+x to boot) if that tutorial is still valid :p
