How to specify the device is described above. If is not specified, PAGE_SIZE is used as alignment. PCI-PCI bridge can be specified, if resource windows need to be expanded. To specify the alignment for several instances of a device, the PCI vendor, device, subvendor, and subdevice may be - specified, e.g., 4096@pci:8086:9c22:103c:198f + specified, e.g., 12@pci:8086:9c22:103c:198f + for the 4096 alignment. ecrc= Enable/disable PCIe ECRC (transaction layer end-to-end CRC checking). bios: Use BIOS/firmware settings. This is the the default. off: Turn ECRC off on: Turn ECRC on. hpiosize=nn[KMG] The fixed amount of bus space which is reserved for hotplug bridge's IO window. Default size is 256 bytes. hpmemsize=nn[KMG] The fixed amount of bus space which is reserved for hotplug bridge's memory window. Default size is 2 megabytes. hpbussize=nn The minimum amount of additional bus numbers
