Macro Definition Documentation

◆ MODULE_ACPI_HIDS

#define MODULE_ACPI_HIDS ( ... )

Value:

static const char* _moduleAcpiHids __attribute__((section(".module_acpi_hids"), used)) = \

__VA_ARGS__

Macro to define what ACPI HIDs a module can handle.

To define what ACPI HIDs a module can handle we define a separate section in the module's binary called .module_acpi_hids this section stores a concatenated string of all ACPI HIDs the module can handle. We dont need terminators for each string as their length is fixed depending on their prefix, we do have a null-terminator at the end of the entire list though.

Example:

MODULE_ACPI_HIDS("PNP0C0A", "PNP0C0B", "ACPI0003");

MODULE_ACPI_HIDS

#define MODULE_ACPI_HIDS(...)

Macro to define what ACPI HIDs a module can handle.

Definition module.h:76

Parameters

...	A variable amount of ACPI HIDs as string literals.

Function Documentation

◆ module_event()

uint64_t module_event ( module_event_t * event )

Propagates a module event to all registered modules.

If the event is a load or unload event, then the event's hid field will be matched against all modules' HIDs, if a match is found that module or modules will be loaded/unloaded.

Parameters

event The event to propagate.

Returns: On success, 0. On failure, ERR and errno is set.

Definition at line 13 of file module.c.

◆ module_init()

void module_init ( void )

Initializes the module system.
