When we use the -kernel parameter to start an elf format kernel relying on fdt, we get the following error:
pcieport 0000:00:01.0: of_irq_parse_pci: failed with rc=-22 pcieport 0000:00:01.0: enabling device (0000 -> 0003) pcieport 0000:00:01.0: PME: Signaling with IRQ 19 pcieport 0000:00:01.0: AER: enabled with IRQ 19 pcieport 0000:00:01.1: of_irq_parse_pci: failed with rc=-22 pcieport 0000:00:01.1: enabling device (0000 -> 0003) pcieport 0000:00:01.1: PME: Signaling with IRQ 20 pcieport 0000:00:01.1: AER: enabled with IRQ 20 pcieport 0000:00:01.2: of_irq_parse_pci: failed with rc=-22 pcieport 0000:00:01.2: enabling device (0000 -> 0003) pcieport 0000:00:01.2: PME: Signaling with IRQ 21 pcieport 0000:00:01.2: AER: enabled with IRQ 21 pcieport 0000:00:01.3: of_irq_parse_pci: failed with rc=-22 pcieport 0000:00:01.3: enabling device (0000 -> 0003) pcieport 0000:00:01.3: PME: Signaling with IRQ 22 pcieport 0000:00:01.3: AER: enabled with IRQ 22 pcieport 0000:00:01.4: of_irq_parse_pci: failed with rc=-22 This is because the description of interrupt-cell is missing in the pcie irq map. And there is a lack of a description of the interrupt trigger type. Now it is corrected and the correct interrupt-cell is added in the pcie irq map. Refer to the implementation in arm and add some comments. changes: V2->V3: 1.Delete unnecessary changes 2.Replace some magic numbers with macro definitions V1->V2: 1.Fallback the incorrect modification of pch_pic interrupt-cells and add the interrupt trigger type in the pcie irq map 2.Add macro definitions for the interrupt trigger types of fdt 3.Refer to the implementation in arm and add some comments.
