Hi,
I'm trying to factor the IRQ Table generation a bit, since the current way to write an IRQ Table plain sucks. This means
* gather all information before actually generating the table * gather information in a readable and adjustable way.
I juggled with the Arima Hdama irq table, since this one seems to work. (See attachment)
Currently I have a couple of defines that are hardcoded into the file. This should maybe be moved to the motherboard configuration files. (At least I would move them and the IRQ_SLOT_COUNT together)
#define IRQ_ROUTER_BUS 1 #define IRQ_ROUTER_DEVFN PCI_DEVFN(4,3) #define IRQ_ROUTER_VENDOR 0x1022 #define IRQ_ROUTER_DEVICE 0x746b #define AVAILABLE_IRQS 0xdef8
Then I substituted the longish irq table entries with a macro IRQ_SLOT which takes the following arguments: * slot number * bus,dev,fn * 4* irq link line id
Example: /* PCI Slot 1 */ IRQ_SLOT (1, 3,1,0, 2,3,4,1 ), /* Let Linux know about bus 1 */ IRQ_SLOT (0, 1,4,3, 0,0,0,0 ),
If there are no objections, I am going to make this change in the code. Who else is having IRQ Table trouble here?
