The NVMe PCI driver is both a client, provider and orchestrator It may be typical for a driver to be both a provider and a client).įor example, in the NVMe Target Copy Offload implementation: In many cases there could be overlap between these three types (i.e., Orchestrator - A driver which orchestrates the flow of data between Memory or doorbell registers to other drivers.Ĭlient - A driver which makes use of a resource by setting up a Provider - A driver which provides or publishes P2P resources like In a given P2P implementation there may be three or more different However, PCI BARs are not typically cache coherent so there areĪ few corner case gotchas with these pages so developers need toīe careful about what they do with them. Memory that is used for P2P transactions needs to be backed by struct The second issue is that to make use of existing interfaces in Linux, Hierarchy will be routable, but it does not require routing Same PCI bridge, as such devices are all in the same PCI hierarchyĭomain, and the spec guarantees that all transactions within the Only supports doing P2P when the endpoints involved are all behind the Therefore, as of this writing, the kernel Simple way to determine if a given Root Complex supports this or not. Transactions between hierarchy domains, and in PCIe, each Root Portĭefines a separate hierarchy domain. One of the biggest issues is that PCI doesn’t require forwarding Make P2P transactions tricky to do in a perfectly safe way. However, there are a number of issues that

Submitting patches: the essential guide to getting your code into the kernel.

A guide to the Kernel Development Process.

There is also some architectures that combine P2P with Server-client. I would consider P2P a good choice because the average internet connection is getting better and better, in the future P2P latency might not be a problem at all.Īlso much about P2P depends on the specific implementation.

If the server has problems, everyone does.

Costs you money to run the servers: definitely not suitable for a free game (unless you let the players set up a dedicated server, but that might be a security problem).

A player's internet connection never affects another's game.

Lower Latency: If the server has a solid connection the latency can be extremely low.

Cheating can be avoided easily (compared to P2P).

If implemented well, scales extremely well (if the work can be distributed across multiple servers).

Easy to implement: It's as straightforward as it gets.

Additionally, the ISP may prevent port forwarding, and it increases the barrier to entry.

May require port forwarding: P2P over the Internet requires port-forwarding, and not everyone is technically-inclined enough to do that.

Latency is usually much greater (although it can be better when joining an internet game with multiple people from a LAN network for example).

A client's internet connection can influence the game for others too.

It's very hard to prevent cheating in such a system, unless you designate an authoritative peer (which will hinder any benefits of scaling well from P2P).

Hard to implement: much harder to create a solid P2P architecture, than a server-client.

More Stable: It can never happen that the server is having problems and no-one can play (implementation dependent).

Very good for data distribution: Suits games where user-created content is dynamically synced (e.g.

Scales very well (up to a certain point when the average client just can't handle the bandwidth).

No need for a central server: this makes it much cheaper, and more viable for low-budget indie games.
