940e9e037e Adds first_scan to LineMetadata. 
Also reorders `Line` fields to match `Scan` fields, just for visual consistency.
 2020-08-16 08:59:37 -04:00
Thomas Harte
230b9fc9e6 Permits multiple simultaneous scan reading ranges. 
Also updates the OpenGL scan target as per the latest movements of things.
 2020-08-12 22:08:41 -04:00
Thomas Harte
637ec35d6a Adds getters for standard colour-space conversion matrices. 
These are just more details on the meaning of the colour spaces, so I think they belong here.
 2020-08-11 19:58:57 -04:00
Thomas Harte
8fa89baf54 Slightly cleans up Xcode project; reenables kiosk-for-Mac builds. 2020-08-10 21:43:32 -04:00
Thomas Harte
8374a5e579 Adds superficially correct compositeSampleLuminance8Phase8 function. 
Thereby uncovering a minor error in my decoding of colour phase.
 2020-08-10 21:33:59 -04:00
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.
 2020-08-10 19:47:47 -04:00

eadda6a967 Further strips OpenGL from the macOS target. 2020-08-09 22:17:27 -04:00

c1dc42a094 Add comment on latent design aim. 
In the hope that I don't forget why I did this.

Thomas Harte
ced4a75a1a Adds note on the buffering scan target's minor adaptation of data_offset. 2020-08-09 20:44:46 -04:00
Thomas Harte
bdcf266e45 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.
 2020-08-08 17:27:32 -04:00
Thomas Harte
583f6b1ba2 Modifies BufferingScanTarget to allow has-a relationship. 
I might switch fully to has-a. Further consideration required.
 2020-08-07 22:03:27 -04:00
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.
 2020-08-07 21:18:08 -04:00

7b1708f0bc Gets explicit that the delegate_ doesn't need a memory barrier. 2020-07-31 18:21:47 -04:00

Thomas Harte
51ad423eca Resolves off-by-one error in line writing, adds diagnostic one-big-lock option. 2020-07-29 22:45:13 -04:00
Thomas Harte
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
Thomas Harte
02f41ee513 This has become the general producer mutex, might as well name it as such. 2020-07-29 21:34:07 -04:00
Thomas Harte

Albeit still probably overspecified.

Initially via two very codependent classes.

9087bb9b08 Allows audio volume to be set. 2020-03-21 22:00:47 -04:00
Thomas Harte
394ee61c78 Starts a switch to reflectable-style runtime options. 
The Amstrad CPC and ZX80/81 have made the jump so far, subject to caveats. The macOS build is unlikely currently to work properly.
 2020-03-16 23:25:05 -04:00

Thomas Harte
90856a0e7a Adds mixdown/up capability to Speaker. 
To deal with occasions when the host machine just always is either mono or stereo, and the emulated machine must cope.

Thomas Harte
49b8e771b5 Adds the messaging that would allow a Speaker to output stereo, semantically. 2020-02-15 13:40:19 -05:00
Thomas Harte
6bda4034c6 Ensures no input data is dropped when changing output rates. 
I think this 'completely' deals with the problem. At least until someone wants dynamic output buffer sizes or something like that. We'll see.

Exposed to SDL users only, for now.
 2020-01-26 13:25:23 -05:00
Thomas Harte
294e09f275 All these 'override's can be 'final's. 
At least for the purpose of being communicative. I doubt there's much to gain in terms of compiler output — the DiskImageHolder can avoid some virtual lookups but nothing else leaps out.

82e5def7c4 Implements get_scan_status, but for scale being incorrect. 2020-01-20 21:58:34 -05:00
Thomas Harte
d97a073d1b Adds the necessary routine for all machines to be able to respond to get_scan_status. 
They all just as the CRT, as all are currently based on the CRT. Which doesn't currently know the total clock rate it would need to in order properly to scale the answer to the question. Further thought coming.

Thomas Harte
35f1a7ab10 Resolves a potential out-of-bounds array access. 
Risk was: allocation exactly joins end of buffer. In which case the next get_data won't wrap the texture y coordinate since it won't spot an x overage.

Thomas Harte
86a6b04d4a Begins attempts to keep track of display metrics. 
i.e. a system that can both make smart decisions about when to use a lower resolution, and hopefully allow some sort of flywheel-esque horizontal retrace synchronisation. And possibly some raster beam chasing?

bee0d09877 Splits display update and draw functions. 
On the Mac, draw is now called without an update for resizing events, and
anything else requested by AppKit. In all other cases — including from
the SDL version — both are called as if they were still a single function.

6b4f6971de Disables upper limit on frame buffer size. 
Filtering is sufficiently imperfect as to make this justifiable only when performance requires it. So I need a test for that. Marked as TODO.

2f9e825728 Forces the outward-communicated composite angles to have the same precision as the cycle counts. 
While also making a minor improvement to output range. Which is neither here nor there.

2f491b5be1 Reintroduces fragment snapping for composite colour sampling. 
Thereby uncovers some sort of slightly-off recording of scan lines. On the Apple II, individual scans reach the ScanTarget at a density of exactly 0.25 colour cycles per pixel. So that timing information propagates exactly. But the whole lines that are composed via ::announce end up trying to fit 0.250154 colour cycles per pixel. Which creates a phase error as the display progresses from left to right.

This will need to be resolved in order to be able to fix the Apple II's intended colour phase. But, also, it's probably what was wrong with the Oric. And, quite possibly, why the single-step shader didn't work.
