*	Add HPET timer for small accurate delays	Damien Zammit	2024-02-08	1	-0/+23
\| \| \| \| \| \| \|	TESTED: This works in qemu correctly TESTED: This works on an AMD board with ACPI v2.0 correctly Message-ID: <20240207050158.1640853-3-damien@zamaudio.com>
*	ACPI: Support XSDT (ACPI >= v2.0)	Damien Zammit	2024-02-01	1	-2/+16
\| \| \| \| \| \| \| \| \|	This enables gnumach to additionally parse the XSDT table if the revision of ACPI is 2. TESTED: Still works on qemu (ACPI v1.0) TESTED: Works on a x86 board with XSDT (ACPI v2.0) Message-ID: <20240131021218.1335821-1-damien@zamaudio.com>

\| \| \| \| \|	GCC already provides this so we don't need to have our own. Message-Id: <Y5+02FVA6jf4GPgA@mars>

*	smp: Add APIC finder and parser	Almudena Garcia	2020-09-19	1	-0/+163
	To find the processors, It's necessary to find the APIC (MADT) table This table is found inside ACPI tables. This set of functions find the MADT table, and parse it to find the APIC structures and register it in the kernel. acpi_parse_apic.h: ACPI structures and function prototypes. acpi_parse_apic.c: ACPI/APIC function definitions.
