This table is used at ** bspstart() to configure the interrupt name & pin for all devices that ** do not have it already specified. If the device is already ** configured, we leave it alone but sanity check & print a warning if ** we don't know about the pin/line the card gives us. ** ** bus = the bus number of the slot/device in question ** ** slot : ** ** If slot != -1, it indicates a device on the given bus in that slot ** is to use one of the listed interrupt names given an interrupt pin. ** ** If slot == -1, it means devices on this bus can occupy any slot- ** and for pci, this means the particular interrupt pin that the ** device signals is therefore dependent on the particular slot. To ** work from the slot to the interrupt pin, the swizzle table is used. ** Once the bus and interrupt pin is known, the correct interrupt name ** can be pulled from the table. The swizzle table relates the ** interrupt pin from the device to the particular interrupt ** controller interrupt pin- so it is quite reasonable for a device on ** bus 1 signalling interrupt pin 1 to show up at the interrupt ** controller as pin 4- this is why the int pin field varies for ** bridged pci busses. ** ** ** opts = bitmap of options that control the configuration of this ** slot/bus. ** ** pin_routes[] = array of pin & vectors that may serve this slot; ** ** pin = the pin # which delivers an interrupt on this route, A=1, ** B=2, C=3, D=4 ** ** int_name[4] = an array of up to 4 bsp-specific interrupt name ** that can be used by this route. Unused entries should be -1. ** The array is of primary use for slots that can be vectored thru ** multiple interrupt lines over the interrupt pin supplied by the ** record. If more than one entry is present, the most preferable ** should supplied first. ** */ #define NULL_PINMAP {-1,{-1,-1,-1,-1}} #define NULL_INTMAP {-1,-1,-1,{}} static struct _int_map mcp750_intmap[] = { { 0, 16, 0, {{1, {5, 19,-1,-1}}, /* pmc slot */ NULL_PINMAP}}, { 0, 14, 0, {{1, {10,18,-1,-1}}, /* onboard ethernet */ NULL_PINMAP}}, { 1, -1, 0, {{1, {24,-1,-1,-1}}, {2, {25,-1,-1,-1}}, {3, {26,-1,-1,-1}}, {4, {27,-1,-1,-1}}, NULL_PINMAP}}, NULL_INTMAP }; static struct _int_map mtx603_intmap[] = { {0, 14, 0, {{1, {10,16,-1,-1}}, /* onboard ethernet */ NULL_PINMAP}}, {0, 12, 0, {{1, {14,18,-1,-1}}, /* onboard scsi */ NULL_PINMAP}}, {0, 16, 0, {{1, {25,-1,-1,-1}}, /* pci/pmc slot 1 */ {2, {26,-1,-1,-1}}, {3, {27,-1,-1,-1}}, {4, {28,-1,-1,-1}}, NULL_PINMAP}}, {0, 17, 0, {{1, {26,-1,-1,-1}}, /* pci/pmc slot 2 */ {2, {27,-1,-1,-1}}, {3, {28,-1,-1,-1}}, {4, {25,-1,-1,-1}}, NULL_PINMAP}}, {0, 18, 0, {{1, {27,-1,-1,-1}}, /* pci slot 3 */ {2, {28,-1,-1,-1}}, {3, {25,-1,-1,-1}}, {4, {26,-1,-1,-1}}, NULL_PINMAP}}, NULL_INTMAP }; /* * This table represents the standard PCI swizzle defined in the * PCI bus specification.
