[PATCH v2 0/1] MR1342: ntdll: Use an acquire/release pair on the IOSB status.
by Zebediah Figura (＠zfigura) 14 Nov '22

14 Nov '22

Based on a patch by Jinoh Kang: https://gitlab.winehq.org/wine/wine/-/merge_requests/155 This patch simplifies the comment somewhat; I don't see it as necessary to fully explain the concept of memory barriers and acquire/release everywhere that they are used. In my opinion, it's necessary and also sufficient to explain why these specific places need an acquire/release pair, what that pair is protecting, and to cross-reference the parts of the pair with each other. I've also removed the IOSB aliasing patches. Personally I think that there's no harm in making our code more endianness-conscious, for things like Winelib, but on the other hand Windows never supported big-endian, and we've resisted adding support for architectures Windows doesn't support (and see also [1]). Since it's not clear to me they're desirable, and they're orthogonal to the purpose of this patch set, I've removed them; they can be submitted later if there is a favourable consensus.

Windows really spawns two threads for each stream? Sheesh. Yes. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1311#note_15679

I don't think we need to check it here anymore with the latest version. Deselected streams will never have pending read requests (or they will shortly complete it after deselection, with either error or a last sample). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1311#note_15680

Yeah, starting / stopping threads dynamically didn't seem like a good idea and it's easier to check the correctness with all stream threads started on open / stopped on close. So instead I keep the thread running but only emit read requests to selected streams. When a stream is deselected, eventually dynamically, it will either fail its read request with `NS_E_NO_MORE_SAMPLES`, or returns a last sample if that happened before, but will then stop receiving read requests. When a stream is selected again, a read request will be emitted and it will resume reading. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1311#note_15678
