Summary

Having two distinct names for the interrupt headers serves to interfere
with most efforts to converge the interrupt frameworks. Simply rename
all of them to "machine/a_bikeshed_string_for_sed_to_target.h". Another name could be substituted,
but right now simply have a random one for this commit.

So the theory is to continue pushing the various interrupt handling implementations closer together. I suspect the INTRNG team may have thought "intr.h" would distinguish their system as being potentially machine-independent, but I think this simply serves to inhibit merging.

As such a case of choosing "intr.h" versus "intr_machdep.h". I think "machine/intr.h" is better as "machine/" already marks them as potentially having architecture quirks. Ideally their similarity will increase, but this will take a while.

ehem_freebsd_m5p.com added a child revision: D32504: kern/intr: remove "irq" from kernel event API.Sep 9 2022, 9:59 PM

If it is felt __FreeBSD_version should be incremented and then check for header name, I've got that prepared. Simply an issue of need a reviewer to request that be done.

I was under the impression D35559 has the right reviewers, but no action has been observed. This is meant as a precursor to the updated D32504. This can improve several places, but does need someone to okay (and commit to the main tree). Then there are the child commits.

Is there a reviewer in the house for D35559?

Ping for D35559. This will be in the way of most attempts to further merge the interrupt interfaces, so deciding the direction would be helpful.

reviews.freebsd.org, where commits go to die?

ehem_freebsd_m5p.com mentioned this in D39333: intrng: expose lower-level device interface for INTRNG.May 10 2023, 1:09 AM

So, most approaches to getting interrupt subsystems to converge are going to need something along the lines of D35559 at some point. Might it be possible to get a decision/activity on D35559?

My thinking was the shorter name machine/intr.h was better, since being in machine already marks the header as being potentially variable from architecture to architecture. Yet the opposite direction of moving arm(64)'s headers to machine/intr_machdep.h would also work. This really needs a decision as forward progress on convergence might be possible if there was activity here.

If someone is up for forward progress on this trivial issue, I recommend doing: (assuming your remote for FreeBSD-Github is "github")

git fetch github refs/pull/1431/head
git cherry-pick 7f0f39b57d08b14420823e7276c9222f37886468

This will likely need an update as files get renamed or modified on a routine basis. Since the Github branch was last updated 2 months ago, it will need (hopefully minor) adjustment.

This seemed a rather simple, yet high value point. Yet it sat here with no reviews and unable to step forward. Then the garbage of D47002 got approved in 5 seconds. I get the message, no it is not merely people got tired of trying to converge the interrupt systems. Many people simply didn't care and unintentionally made it extremely difficult.
