2026-08-04 22:12:07 -07:00

main_test.go

Take the rate epoch from the slowest stream's frontier, since reading a bucket claims every stream has delivered through it

main.go

Hold a fatal error on the framebuffer and reboot in five minutes rather than exiting, since init's death drops the kernel's panic screen over the cause

Build i40e into the appliance kernel, whose forbidden list predated the noise pair that needs it

2026-08-05 21:46:15 -07:00

2026-08-04 15:46:12 -07:00

docs/README.md

cabletest docs

Project knowledge that moves and versions with the repo.

General:

goals.md — what cabletest is for and what it must output.
state.md — where things are now: committed vs stashed, the box and what's in it, bringup progress, open items. All current-placement state lives here and only here.
hardware.md — host rules: interface conventions, tuning, how to run.
measurement.md — how to measure correctly; performance results and dead ends.
open-questions.md — the open problems, with their current answers.

Per-device (each directory: device doc + its datasheets):

nics/ — the transport rule, the comparison table, and one directory per NIC: x520, connectx-5, x710, e810.
modules/ — module inventory, media-lies table, the shared IEEE register set, RollBall protocol, cable-length physics, and one directory per module: fs, wiitek, fibergaga.
