Some additional ACPI values are defined in Acpi1_0.h and 22 Acpi2_0.h. 23 To make changes to the MADT, it is necessary to update the count for the 24 APIC structure being updated, and to modify table found in Madt.c. 25 26 --*/ 27 28 #ifndef _MADT_H 29 #define _MADT_H 30 31 // 32 // Statements that include other files 33 // 34 #include "AcpiTablePlatform.h" 35 #include <IndustryStandard/Acpi10.h> 36 #include <IndustryStandard/Acpi20.h> 37 #include <IndustryStandard/Acpi30.h> 38 #include "Platform.h" 39 40 // 41 // MADT Definitions 42 // 43 #define EFI_ACPI_OEM_MADT_REVISION 0x00000000 44 // 45 // Multiple APIC Flags are defined in AcpiX.0.h 46 // 47 #define EFI_ACPI_1_0_MULTIPLE_APIC_FLAGS (EFI_ACPI_1_0_PCAT_COMPAT) 48 #define EFI_ACPI_2_0_MULTIPLE_APIC_FLAGS (EFI_ACPI_2_0_PCAT_COMPAT) 49 #define EFI_ACPI_3_0_MULTIPLE_APIC_FLAGS (EFI_ACPI_3_0_PCAT_COMPAT) 50 #define EFI_ACPI_4_0_MULTIPLE_APIC_FLAGS (EFI_ACPI_4_0_PCAT_COMPAT) 51 52 // 53 // Define the number of each table type. 54 // This is where the table layout is modified. 55 // 56 #define EFI_ACPI_PROCESSOR_LOCAL_APIC_COUNT MAX_CPU_NUM 57 #define EFI_ACPI_LOCAL_APIC_NMI_COUNT MAX_CPU_NUM 58 #define EFI_ACPI_IO_APIC_COUNT 1 59 #define EFI_ACPI_INTERRUPT_SOURCE_OVERRIDE_COUNT 2 60 #define EFI_ACPI_NON_MASKABLE_INTERRUPT_SOURCE_COUNT 0 61 #define EFI_ACPI_LOCAL_APIC_ADDRESS_OVERRIDE_COUNT 0 62 #define EFI_ACPI_IO_SAPIC_COUNT 0 63 #define EFI_ACPI_PROCESSOR_LOCAL_SAPIC_COUNT 0 64 #define EFI_ACPI_PLATFORM_INTERRUPT_SOURCES_COUNT 0 65 66 // 67 // MADT structure 68 // 69 // 70 // Ensure proper structure formats 71 // 72 #pragma pack(1) 73 // 74 // ACPI 1.0 Table structure 75 // 76 typedef struct { 77 EFI_ACPI_1_0_MULTIPLE_APIC_DESCRIPTION_TABLE_HEADER Header;
