Enable ethernet networking devices #19

Open frno7 opened 5 years ago

frno7 commented 5 years ago

The PlayStation 2 expansion bay and later PlayStation 2 models with built-in hardware support the ethernet networking technology. Device driver starting points are drivers/ps2/smap.c and drivers/ps2/smaprpc.c, that are not quite working in the latest versions of the kernel. These two drivers should probably be combined into a single device driver.

In the meantime, USB network devices can be used as an alternative, but see #17. See also #11 and #18.

The SMAP itself is not faultless. FYI, If you ever manage to make it go fast: https://github.com/ps2dev/ps2sdk/commit/dc918c3e511df53a5cc187015d0eaf5046966bb6#diff-a275d0f23cde1dd3f6c9d427a99f73be It starts to exhibit stability problems once frames start transferring above 7MB/s.

Oh, many thanks @sp193, that was very helpful to learn.

So... How it goes at this forefront?) Do it requires a special IOP module? If yes, is this module united for both FAT and SLIM or there have to be a two (three? - for DTL...) of them? At the first message there is a note that

but there was never even a chance to test it...

Yes, we’d need an IOP module for Ethernet. I’m hoping we could have the same network driver support all PlayStation 2 hardware variants, since that’d be easier for people, to not have to worry about which driver to use.

4.x and 5.x Linux kernels have a lot of generic network subsystem changes, and so some updates are needed to compile the old drivers. Plus, the Sony BIOS isn’t available in these Linux kernels any more.
