Example Code for MPtable

This source is to do a propper mptable setup on M57SLI.

Setup the registers 0x7c-0x84 with the IRQ Values you want to have: 

 /*I/O APICs:    APIC ID Version State           Address*/
       {
               device_t dev;
               struct resource *res;
               uint32_t dword;
               dev = dev_find_slot(bus_mcp55[0], PCI_DEVFN(sbdn+ 0x1,0));
               if (dev) {
                       res = find_resource(dev, PCI_BASE_ADDRESS_1);
                       if (res) {
                               smp_write_ioapic(mc, apicid_mcp55, 0x11, res->base);
                       }
                       dword = 0xc643c643;
                       pci_write_config32(dev, 0x7c, dword);
                       dword = 0x8da01009;
                       pci_write_config32(dev, 0x80, dword);
                       dword = 0x200018d2;
                       pci_write_config32(dev, 0x84, dword);
               }
       }

According to the Registers 0x7c-0x84 do the IRQ setup: 

 #define PCI_INT(bus, dev, fn, pin)                                      \
       smp_write_intsrc(mc, mp_INT, MP_IRQ_TRIGGER_LEVEL|MP_IRQ_POLARITY_LOW,\
                        bus_mcp55[bus], (((dev)<<2)|(fn)), apicid_mcp55, (pin))

       PCI_INT(0,sbdn+1,1, 10); /* SMBus */
       PCI_INT(0,sbdn+2,0, 22); /* USB */
       PCI_INT(0,sbdn+2,1, 23); /* USB */
       PCI_INT(0,sbdn+4,0, 21); /* IDE */
       PCI_INT(0,sbdn+5,0, 20); /* SATA */
       PCI_INT(0,sbdn+5,1, 21); /* SATA */
       PCI_INT(0,sbdn+5,2, 22); /* SATA */
       PCI_INT(0,sbdn+6,1, 23); /* HD Audio */
       PCI_INT(0,sbdn+8,0, 20); /* GBit Ethernet */
       PCI_INT(1,0x0a,0, 18);   /* Firewire */

       /* The PCIe slots, each on its own bus */
       k = 1;
       for(i=0; i<=3; i++){
               for(j=7; j>=2; j--){
                       if(k>3) k=0;
                       PCI_INT(j,0,i, 16+k);
                       k++;
               }
               k--;
       }

       /* On bus 1: the PCI bus slots...  */
       k=2;
       for(i=0; i<=3; i++){
               for(j=6; j<=10; j++){
                       if(k>3) k=0;
                       PCI_INT(1,j,i, 16+k);
                       k++;
               }
       }

Example ACPI static IRQ routing

For this the registers 0x7c-0x84 need to be set so that this static routing will work. 

                       /* PCI Routing Table */
                       Name (_PRT, Package () {
                               Package (0x04) { 0x0001FFFF, 0x01, 0x00, 0x0A }, /* 0x1 - 00:01.1 - IRQ 10 - SMBus */
                               Package (0x04) { 0x0002FFFF, 0x00, 0x00, 0x16 }, /* 0x2 - 00:02.0 - IRQ 22 - USB */
                               Package (0x04) { 0x0002FFFF, 0x01, 0x00, 0x17 }, /* 0x2 - 00:01.1 - IRQ 23 - USB */
                               Package (0x04) { 0x0004FFFF, 0x00, 0x00, 0x15 }, /* 0x4 - 00:04.0 - IRQ 21 - IDE */
                               Package (0x04) { 0x0005FFFF, 0x00, 0x00, 0x14 }, /* 0x5 - 00:05.0 - IRQ 20 - SATA */
                               Package (0x04) { 0x0005FFFF, 0x01, 0x00, 0x15 }, /* 0x5 - 00:05.1 - IRQ 21 - SATA */
                               Package (0x04) { 0x0005FFFF, 0x02, 0x00, 0x16 }, /* 0x5 - 00:05.2 - IRQ 22 - SATA */
                               Package (0x04) { 0x0006FFFF, 0x01, 0x00, 0x17 }, /* 0x6 - 00:06.1 - IRQ 23 - HD Audio */
                               Package (0x04) { 0x0008FFFF, 0x00, 0x00, 0x14 }, /* 0x8 - 00:08.0 - IRQ 20 - GBit Ethernet */
                       })

                         Device (PEBA) /* PCI-E Bridge A */
                       {
                               Name (_ADR, 0x000A0000)
                               Name (_UID, 0x00)
                               Name (_BBN, 0x02)
                               Name (_Prt, Package () {
                                       Package (0x04) { 0x0000FFFF, 0x00, 0x00, 0x12 },
                                       Package (0x04) { 0x0000FFFF, 0x01, 0x00, 0x13 },
                                       Package (0x04) { 0x0000FFFF, 0x02, 0x00, 0x10 },
                                       Package (0x04) { 0x0000FFFF, 0x03, 0x00, 0x11 },
                                       })
                       }

Bridge B-F needs also to get a routing setting, but not listed here.
