246b474a25
Removes ONE_BIG_LOCK, having effectively neutered it anyway.
...
Starts work on more explicit API usage validation. Maybe the issue isn't a race condition?

Thomas Harte
525233e10b
Ensures all input data types are parseable in Metal.
...
Though now I need to think a bit more about the best way to compose signal-type conversions, and whether output-type calculations (i.e. gamma, brightness) are applied.

Having learnt a bit more: eliminates Metal attribute tags, switches to more natural expression of structs.
...
Also thereby eliminates the need for a forced alignas(4) on various structs.

Thomas Harte
583f6b1ba2
Modifies BufferingScanTarget to allow has-a relationship.
...
I might switch fully to has-a. Further consideration required.

Thomas Harte
4c9418f59a
Guarantees alignof(4) on all GPU-bound structures.
...
Taken as given: Metal's requirement here is reasonable enough that it'll either be the same as other frameworks, or at least possibly help them down a fast path.

72a8fef989
Switches to much more straightforward Line/LineMetadata storage.
...
Spoiler: covering this whole segment behind producer_mutex_ seems to resolve all output issues, so clearly the existing logic isn't functioning correctly. Making it simpler seems like a pretty obvious way to get to the bottom of that.
2020-07-29 21:49:17 -04:00

This has become the general producer mutex, might as well name it as such.
