https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=265974 --- Comment #11 from Mark Johnston --- I do think the deferred advance might still be incorrect on platforms where FreeBSD's atomic_thread_fence_rel() does not provide a store/load barrier, such as POWER. -- You are receiving this mail because: You are the assignee for the bug.
[Bug 265974] SMR has several missing barriers
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=265974 --- Comment #10 from Mark Johnston --- (In reply to Pierre Habouzit from comment #9) dmb st only orders stores, but that's not sufficient to implement a release fence. For what it's worth, LLVM on FreeBSD 14/arm64 compiles atomic_thread_fence(memory_order_release) to a "dmb ish", same as atomic_thread_fence(memory_order_seq_cst). -- You are receiving this mail because: You are the assignee for the bug.

--- Comment #9 from Pierre Habouzit ---
`atomic_thread_fence_rel()` is a `dmb sy` ? I would have expected that to be a
`dmb st` ..
but indeed it shows I'm not familiar with with FreeBSD:
```C
static __inline void
atomic_thread_fence_rel(void)
{
dmb(sy);
}
```
and indeed it makes the deferred advance correct then.
It also means smr_synchronize() has a stronger semantics than I expected
already and makes the smr_poll barrier on entry useless because the
`atomic_load_acq_int()` in smr_poll() already give the semantics I was after on
entry.
I think you might be right that the one on exit of smr_poll() isn't quite
needed. I think I just didn't think it through and just took
`ck_epoch_synchronize_wait` as an example and just was like "it needs one so
smr_scan does too" but trying to come up with a reason why it breaks yields
nothing..
