Name: ms_irq_routing_table +; +; Type: Structure Array +; +; Description: The information below is used for two purposes: +; 1. PCI IRQ routing during POST +; 2. Runtime dynamic IRQ routing (using Int 1A functions +; B10E / B10F) +; +; The IRQ routing table should contain one entry for each +; on-board PCI device or PCI slot. Chipset devices such as host +; bridges and ISA bridges do not need an entry. A generic BIOS +; can contain a few unused entries that BCP can use when adapting +; a generic BIOS to a customized BIOS for a motherboard containing +; on board devices such as PCI IDE, PCI SCSI, or PCI Network chips. +; BCP can also use a blank entry if a motherboard OEM decides to +; put an extra +; PCI slot on their board. +; +; The rth_pci_device_limit byte should be set to the total number +; of entries that are present including any blank entries. +; +; The rth_pci_device_count byte should be set to the number of +; non-blank entries (entries that are actually used in this BIOS). +; +; The rth_pci_dedicated_irqs word is a bitmask of IRQs that are +; dedicated to the PCI bus. (Bit 0 = IRQ 0, ..., Bit 15 = IRQ +; 15) In most cases this word will be set to all 0's. This +; word may be used in systems that implement IRQ routing with +; jumpers. +; +; The fields in each table entry are discussed below: +; +; - PCI Bus Number: Most boards contain only a single PCI bus, +; so this byte should usually be set to 0. If a board has +; multiple PCI busses, then this byte should be set to indicate +; which bus the device or slot is on. +; +; - Dev Num: This field should be set to a slot's or device's +; address on the PCI bus shifted left by three bits (the device +; number should be in bits 7:3 and bits 2:0 should be 000). +; +; - Int A Pin, Chipset Reg: This field should be set to the +; chipset register number that controls this slot's (or device's) +; Int A Pin. The value in this field is basically arbitrary, +; the value is returned by the function rth_pci_get_irq_reg. +; Slots and devices that share the same chipset interrupt signal +; should have the same value for this field. +; For example: +; if Slot 1's Int A pin and Slot 2's Int B pin are both connected +; to the same chipset interrupt signal, then the Chipset Reg +; value for Slot 1 Int A should match Slot 2 Int B. The core +; BIOS (and configuration software) need this information to +; know how IRQs are shared between slots. If a slot or device +; has nothing connected to its Int A pin, then this field should +; be set to 0. If a slot or device has its Int A pin hardwired +; directly to an IRQ, then set this field to 0Fxh (where x is +; 0-F for IRQ 0 - IRQ 15). This is useful if a motherboard has +; a PCI IDE chip that has its Int A pin hardwired to IRQ 14. +; +; - Int A Pin, Bitmap of IRQs Routeable to Pin: This field should +; be set to indicate which IRQs the chipset is capable of routing +; to the slot's (or device's) Int A pin. If the value for Chipset +; Reg (see above) was set to 0, then set all bits in this field +; to 0 also. If the value for Chipset Reg was set to 0Fxh to +; indicate a hardwired connection to a certain IRQ, then only one +; bit corresponding to that IRQ should be set in this field. +; +; - Int B,C,D Pin, Chipset Reg: These fields work exactly like +; the Chipset Reg field for Int A Pin (see above). +; +; - Int B,C,D Pin, Bitmap of IRQs Routeable to Pin: These fields +; work exactly like the corresponding field for Int A Pin (see above). +; +; - Physical Slot Number: This field should be set to the slot +; number of a PCI slot as it appears to the end user. Numbers +; like 1, 2, 3, 4 should be used. On board PCI devices such as +; PCI IDE chips should have this field set to 0 to indicate that +; the device is not a removable card that is plugged into a slot. +; Configuration software can use this value to translate a PCI +; device number (0 - 1F) to a value that is meaningful to an end +; user. +; +; - Reserved Byte: Always set to 0. +; +; Notes: +; +;---------------------------------------------------------------------------- +;<AMI_THDR_END> + +ALIGN 16 + +ms_irq_routing_table LABEL BYTE +; MS IRQ routing table header. this header is followed by all PCI slot entries. +; MSIRQ_HEADER <> + db '$PIR' ; signature + db 0, 1 ;version (low byte = minor, high byte = major) + dw size(MSIRQ_HEADER) + (OFFSET Irq_table_empty_entries - \ + OFFSET rth_pci_irq_routing_table) ;length of routing table including header and slots + db 0 ;PCI IRQ Router bus# (to be updated during runtime) + db 0 ;PCI IRQ Router dev#(7:3), func#(2:0), to be updated during runtime. + dw 0 ;bitmap of IRQs used exclusively for PCI + dd 0 ;VendorID, DeviceID of compatible IRQ router (low word = VendorID, high word = DeviceID) + dd 0 ;MiniPort Data + db 11 dup(0); reserved bytes (set to 0) + db 0 ;checksum (to be updated during runtime) + +rth_pci_irq_routing_table LABEL BYTE + include oempir.inc +pci_irq_entry <> + +Irq_table_empty_entries LABEL BYTE +; PCI IRQ routing entries defined after this label are not included. + + PUBLIC IRQ_Table_end +IRQ_Table_end LABEL BYTE + +PCIDATA_SEG ENDS +end + + +;********************************************************************** +;********************************************************************** +;** ** +;** (C)Copyright 1985-2010, American Megatrends, Inc. ** +;** ** +;** All Rights Reserved. ** +;** ** +;** 5555 Oakbrook Pkwy, Suite 200, Norcross, GA 30093 ** +;** ** +;** Phone: (770)-246-8600 ** +;** ** +;********************************************************************** +;********************************************************************** diff --git a/Core/EM/CSM/PciInfo.asm b/Core/EM/CSM/PciInfo.asm new file mode 100644 index 0000000..0662e0a --- /dev/null +++ b/Core/EM/CSM/PciInfo.asm @@ -0,0 +1,83 @@ +;********************************************************************** +;********************************************************************** +;** ** +;** (C)Copyright 1985-2010, American Megatrends, Inc. ** +;** ** +;** All Rights Reserved. ** +;** ** +;** 5555 Oakbrook Pkwy, Suite 200, Norcross, GA 30093 ** +;** ** +;** Phone: (770)-246-8600 ** +;** ** +;********************************************************************** +;********************************************************************** + +;********************************************************************** +; $Header: /Alaska/SOURCE/Modules/CSM/Generic/Core/PciInfo.asm 6 1/12/10 11:46a Olegi $ +; +; $Revision: 6 $ +; +; $Date: 1/12/10 11:46a $ +;********************************************************************** +;********************************************************************** +; Revision History +; ---------------- +; $Log: /Alaska/SOURCE/Modules/CSM/Generic/Core/PciInfo.asm $ +; +; 6 1/12/10 11:46a Olegi +; Copyright message updated. +; +; 5 4/27/07 5:13p Olegi +; CSM.CHM file preparation. +; +; 4 8/24/06 3:05p Felixp +; 1. x64 support +; 2.
