Porteus Kernel Builder

Here is a place for your projects which are not officially supported by the Porteus Team. For example: your own kernel patched with extra features; desktops not included in the standard ISO like Gnome; base modules that are different than the standard ISO, etc...

APorteus XFCE 64bit Kernel 5.12-rc3 boot
with cheatcode "mitigations=off".

[Boot time & Benchmark]
Boot time: by command "systemd-analyze"
Startup finished in 6.720s (kernel) + 2.089s (userspace) = 8.810s
graphical.target reached after 1.944s in userspace

Benchmark: by /usr/bin/hardinfo (System Profiler and Benchmark)

----------------------------------------
without cheatcode "mitigations=off"

[Boot time & Benchmark]
Startup finished in 9.785s (kernel) + 3.255s (userspace) = 13.041s

babam, it looks like as SELinux :bad: (about LSM)
and you are right and these options are must be disabled.
In the next build I will disable it. Not bad if neko will do this too.

Thanks.

CONFIG_DRM_VBOXVIDEO=m
CONFIG_VBOXGUEST=m
by default?

Yes

Because I use Btrfs for persistent (partition / container file).

You can try a partition or container file formatted to Btrfs and then use it as persistent (changes cheatcode)
Sorry, my English is bad.

@babam

The pre-prepared CONFIG applies to the majority of Porteus users.
Individual CONFIG changes are not included
to prevent the kernel size from becoming too large,
so please follow the steps below to make your own changes before compiling.

1. Prepare the latest KERNEL BUILDER usage environment
Ex: APorteus-XFCE_ru-v21.03.20-x86_64.iso : This ISO can be used as "Kernel Builder"
ArchLinux packages manager for Porteus (Post by neko #81802)

2. Kernel Build
<GUI>
menu ---> "Kernel Builder"
"Kernel Builder Directory" : /buildDIR/
"Kernel Version" : 5.11.8
"64Bit" : select
"download : check ON
"expand & AUFS patch" : select
push "OK" button.
&
push "OK" button of confirm window.

<CUI>

Code: Select all

% su
# cd /buildDIR/v5.11.8/64/linux-5.11.8
# make menuconfig
..
(your own modification)
..
#
<GUI>
menu ---> "Kernel Builder"
"Kernel Builder Directory" : /buildDIR/
"Kernel Version" : 5.11.8
"64Bit" : select
"compile" : check ON
"Create FW" : check ON
push "OK" button.
&
push "OK" button of confirm window.


Thanks.

Have this VirtualBox error in kernel 5.11.8 and 5.12-rc3:

Code: Select all

The VirtualBox Linux kernel driver is either not loaded or not set up
correctly. Please try setting it up again by executing

'/sbin/vboxconfig'

as root.

If your system has EFI Secure Boot enabled you may also need to sign 
the kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) before
you can load them. Please see your Linux system's documentation for
more information.

where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED
(-1908) - The support driver is not installed. On linux, open returned
ENOENT. 
Any ideas !?

@AcnapyxoB, how exactly did you build this vbox module?
