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.

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.

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

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.

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.

b514756272 Adds the option to run machines at a multiple of their real speeds. 
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.

a71c5946f0 Ensures proper manipulation of scan_statuses, leading to the correct result out of a CRTMachine. 
Possibly with the exception of the TMS, as I appear to have uncovered an unrelated issue there.

e7fff6e123 Minor step towards correct answers: divide by time_multiplier_. 2020-01-20 22:33:51 -05:00
Thomas Harte
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?

Thomas Harte
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.

Thomas Harte
7bb90c78d9 Resolves out-of-bounds initial condition whenever this loop began with start_line = 2047. 
This, I believe, was the remaining cause of screen flashes.
 2019-02-24 19:50:19 -05:00
Thomas Harte
a6e61ef83b Reverts the clear colour to black. 
The change was related to debugging; it was not intentionally committed.

c775a6c0f8 Introduces but disables a couple of bits of logging that might be helpful again in the future. 2019-02-24 14:30:39 -05:00
Thomas Harte
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.
 2019-02-24 14:29:43 -05:00
Thomas Harte
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.
