Audiolinux V3: Added option for IRQ balancer and UKSMD userspace KSM helper daemon (KSM is a memory-saving de-duplication feature)

The isolated cores script has been improved!
Is now possible to define 1, 2 or more groups of isolated cores. For each you can define the assigned application(s) or irq(s)
The previous Expert menu option 13 'CPU ISOLATED CORES Assign core to irq or application' has been integrated in 18 'ISOLATED CPU CORES configuration'
The configuration file is /opt/configuration/isolated.conf

Fixed option 6 'HQPLAYER Multicore/Cuda configuration' if you are using hqplayer as root
Improved option 13 'REALTIME PRIORITY to standard or extreme' in System menu

To backup/restore your library you should use the option Roon backup in Audio menu
Stability and security could be improved
USER root
You can mount shares from Roon control point
You can backup/restore your library from Roon control point
Added network irq to 9 'AUDIO IRQ monitor' (status menu)
AUDIO CARD status can now display correctly the status of Diretta alsa remote DAC

PROFILES MENU: Fixed Custom2 and Custom3 profiles not applied correctly
Corrected wrong display of physical/virtual cores in hyper-threading option (Expert menu)
All the scripts for isolated cores have been improved and changed substantially.
As a consequence, also the scripts for boot mode and frequency scaling had to be changed
The new system solves also the problem that with some CPU, after disabling hyper-threading, core numbers are not in sequence, preventing proper functioning of core isolation

Version 5.3.0

1) Full system update

2) Kernel 6.3.1-1-cachyos-rt

3) Menu 570

Fixed and improved output of 6 'CLEAN system' in System menu

New rtpriority 1.3 released
Improved option 1 REALTIME MANUAL ASSIGNMENT configuration in Expert menu now is offering 2 options for selecting IRQ with realtime priority:
1 - Automatic -> recommended, this will give priority only to USB bus where the card is connected, after giving the 'address' selected from a list (iSerial). This way with the new rtpriority 1.3 you can be sure that only the IRQ related to your DAC are selected, even if they are changing after a reboot
2 - Manual -> possible values: irq, list of irqs, xhci, ehci, snd

Improved option 19 NETWORK/USB power saving now is using product identity to avoid address change after a are reboot
Temporarily disabled reflector option in Update menu -> 20 UPDATE Archlinux/V3 servers because of upstream bug
