Apply your CSV field map to the capture from Inspect. Offsets refer to PCI config space, not BAR memory.

Guest snapshots belong to this browser. Google sign-in creates a separate local workspace; it does not upload or sync captures.
FROM THE BENCH TO AN ANSWER
Bring a capture.
Leave with context.
You already have the raw data. The workbench makes it easier to understand, compare and hand off.
1. Capture one device on Linux
Find its address with lspci -D, then capture the config space for that device:
sudo lspci -s 0000:01:00.0 -xxxReplace the address with your device’s address. Extended capabilities require a supported 4 KiB capture (-xxxx). Some devices react poorly to config reads; use an existing dump or check your device documentation first. See the lspci manual ↗.
2. Paste, decode, compare
Paste the hex rows for one device. Missing bytes remain unknown. To investigate a change, compare a known-good capture with one taken after the problem appears. Compare the same device and capture method.
3. Share the evidence
Export a Markdown report or JSON for your issue tracker. Reports include observed values, offsets and limitations. A capture cannot establish root cause, prove DMA performance or reveal a vendor-specific LTSSM state.
What works today?
PCI IDs, header type, command/status, BAR values, PCIe link capability/status, selected error flags, byte-by-byte comparisons, CSV config-space field maps and local snapshots. No agent, live register access, hardware writes, cloud storage or subscription billing is included in this preview.
THE PROBLEM WORTH PAYING TO SOLVE
Stop rebuilding the story
every time a board fails.
A hex decoder helps once. A trusted baseline, a repeatable regression and evidence your whole team can use help on every release. That’s the product we’re building toward.
01 / BRING-UP
Know where you started.
Keep the working state next to the board and firmware version that produced it.
02 / REGRESSION
Catch what changed.
Compare the next build against an agreed baseline, with expected differences separated from surprises.
03 / HANDOFF
Send evidence, not guesses.
Give the firmware engineer, driver team or supplier one clear report to investigate.
START FREE. SHAPE WHAT COMES NEXT.
