With this in mind, we can burst the minimum number of buffers. Rewrite descriptors with atomics 2025-07-18T00:50:40+00:00 Ian McIntyre me@mciantyre.dev 2025-07-18T00:50:40+00:00 urn:sha1:6498f85de3078ad7c3206c22c690ecb3d0fa71bb The memory ordering ensures that operations to normal memory are synchronized with operations on device memory, at runtime. I've seen this play out in the transmit path: writes to the transmit buffer's flags weren't reaching memory by the time the MAC was checking, resulting in missing packets. Moving the fence works, but it's better to use atomics.

First commit 2023-11-26T20:11:27+00:00 Ian McIntyre ianpmcintyre@gmail.com 2023-10-22T22:23:56+00:00 urn:sha1:c7e5123f6604fbb9ca510f01af9b60e777bf57b4 A prototype of an i.MX RT ENET driver. There's design decisions I'm thinking of changing. Nevertheless, the smoltcp support seems to be working; an 1170EVK can act as a DHCP client and a TCP loopback server.
