ACPI subsystem includes 3 types of parsers that are created during runtime, each one capable of parsing ACPI tables at different level. ACPIParser is the most basic parser which is essentialy a parser that can't parse anything useful, due to a user request to disable ACPI support in a kernel boot parameter. ACPIStaticParser is a derived class from ACPIParser, which is able to parse only static data (e.g. FADT, HPET, MCFG and other tables), thus making it not able to parse AML (ACPI Machine Language) nor to support handling of hardware events and power management. This type of parser can be created with a kernel boot parameter. ACPIDynamicParser is a derived class from ACPIStaticParser, which includes all the capabilities of the latter, but *should* implement an AML interpretation, (by building the ACPI AML namespace) and handling power & hardware events. Currently the methods to support AML interpretation are not implemented. This type of parser is created automatically during runtime if the user didn't specify a boot parameter related to ACPI initialization. Also, adding strncmp function definition in StdLib.h, to be able to use it in ACPIStaticParser class. |

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 me, for me, based on the things I like.
If you like some of the same things, you are welcome to join the project. It would be great to one day change the above to say "this is a system by us, for us, based on the things we like." :^)
I 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.
