pci: clean up empty lines in .c and .h files

2020-09-01T22:00:07+00:00

Re-commit r299467 having fixed the build:

2016-05-16T09:15:50+00:00

Add a new get_id interface to pci and pcib. This will allow us to both
detect failures, and get different PCI IDs.

For the former the interface returns an int to signal an error. The ID is
returned at a uintptr_t * argument.

For the latter there is a type argument that allows selecting the ID type.
This only specifies a single type, however a MSI type will be added
to handle the need to find the ID the hardware passes to the ARM GICv3
interrupt controller.

A follow up commit will be made to remove pci_get_rid.

Add support for PCIe ARI

2014-04-01T16:02:02+00:00

PCIe Alternate RID Interpretation (ARI) is an optional feature that
allows devices to have up to 256 different functions.  It is
implemented by always setting the PCI slot number to 0 and
re-purposing the 5 bits used to encode the slot number to instead
contain the function number.  Combined with the original 3 bits
allocated for the function number, this allows for 256 functions.

This is enabled by default, but it's expected to be a no-op on currently
supported hardware.  It's a prerequisite for supporting PCI SR-IOV, and
I want the ARI support to go in early to help shake out any bugs in it.
ARI can be disabled by setting the tunable hw.pci.enable_ari=0.
