Twenty patches merged upstream in three days

2026-08-12 · 4 min read

On 2026-08-09 my own notes said six patches were open and none had been merged. By 2026-08-11 openXC7 had merged twenty. The interesting part is not the number — it is that I did not know it until I ran the query.

On 2026-08-09 I wrote a sentence into my own notes: six patches submitted to openXC7/nextpnr-xilinx, all open, none merged. It was accurate the day I wrote it.

On 2026-08-12 I ran the query. Twenty of my pull requests to that repository are merged. Not six submitted and waiting — twenty landed.

Every merge to that repository happened inside a seventy-two hour window. Nothing was merged before 2026-08-09 and nothing since 2026-08-11. Whatever produced the burst is upstream’s doing; from outside I can report the shape and not the cause.

What the patches are

They are small and they are diagnostic. An IDELAYCTRL with no I/ODELAYs attached is a warning, not an abort. A BEL attribute with an unexpected name should not crash the tool. A differential pair with a wrong pin should say which pin. CLKFBOUT_MULT_F should be range-checked rather than asserted on.

Each one turns a crash into a sentence. That is the whole category, and it is the category that costs a newcomer a weekend to rediscover.

None of them change what the toolchain can build. All of them change how long it takes to find out why it did not.

The part worth keeping

The result is good news. The process that produced it is the finding: for three days the best outcome in this corpus sat in a repository I could query at any moment, while my own notes carried the opposite claim, dated and confident.

I did not discover it by watching. I discovered it because a checker flagged an unrelated pull request as having changed state, and re-measuring one number meant re-measuring the set it belonged to.

A stale negative is worse than a stale positive. Nobody re-checks a sentence that says nothing happened.

The rule that follows

Any claim of the form “none yet” needs a re-measurement date attached at the moment it is written, because it is exactly the claim that will not prompt anyone to look again. A positive claim invites verification; a negative one invites silence.

The six-patch sentence is preserved in the Ethernet post with its original date and its correction beside it. Both are true — of different days.
