Now we don't send raw numbers, but we let the IRQController object to figure out the correct IRQ number. This helps in a situation when we have 2 or more IOAPICs, so if IOAPIC 1 is assigned for IRQs 0-23 and IOAPIC 2 is assigned for IRQs 24-47, if an IRQHandler of IRQ 25 invokes disable() for example, it will call his responsible IRQController (IOAPIC 2), and the IRQController will subtract the IRQ number with his assigned offset, and the result is that the second redirection entry in IOAPIC 2 will be masked. |

SerenityOS
Graphical Unix-like operating system for x86 computers.
About
SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.
Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.
I (Andreas) regularly post raw hacking sessions and demos on my YouTube channel.
Sometimes I write about the system on my github.io blog.
I'm also on Patreon and GitHub Sponsors if you would like to show some support that way.
