Crate Addition Request: PCI emulation

[sameo]

Crate Name

pci

Short Description

A PCI host bridge emulation.

Why is this crate relevant to the rust-vmm project?

• Support for using PCI as a dynamic device enumeration bus for rust-vmm guests
• Support for PCI device emulation
• Support for device passthrough, in combination with the vfio crates

Is this PCI or PCIe like CH uses?

Most likely PCI-e if we want it to support modern PCI-e devices passthrough and have them being exposed as such.

Sounds good! +1

Everyone is ok with simply calling it pci? Or do we want to be fancy with vmm-pci ?

[andreeaflorescu]

pci is already taken on crates.io. The other crates are named vm-something. Should we use the same naming convention?

Do we envision multiple pci related crates? And in this case should we create a repository pci-ws (or something like that) which would then contain a single crate called vm-pci (or the name we decide to give it)?

[sameo]

I don't think we need several pci related crates. So I vote for vm-pci.

Hi all,

We'd like to contribute to vm-pci. We want to start with the PCI configuration space abstractions, which would help users of the crate interact with a common interface for accessing the PCI configuration space. It will also be a place for PCI constants (such as IDs related to PCI capabilities defined in the specification).

We're ready to start work here and we'd like to have the crate created so we can post PRs.

https://github.com/rust-vmm/vm-pci I've created the repo.

We still need to setup the CI for the repository, we'll update this issue once this is done.
