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

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

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

text.go

Cut the comments back to the genuinely subtle ones

2026-08-01 16:14:12 -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.
