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.

Disables multisampling, since there's no way it's being helpful.

Split the static analyser functionality so that it's possible just to ask for the set of media implied by a particular file. Extended ConfigurationTarget so that media alone can be pushed to a machine.

Adjusted parameter name to match documentation. I think it's a carry-over from before I was passing the whole event along.

Delegates are all nullable, naturally.

Rewired the existing cause-an-update route from the OpenGLView through the best-effort updater.

Back to asynchronous updates and drawing, to try to improve guarantees on audio latency; experimenting with whether other parts of the approach are fundamentally flawed; added a broad-phase for scheduled updates on the 2600.

Issues appear to be around timing generally. Working on it.

Made sprite placement consistent at least. Not necessarily yet correct.

Fixed error that would prevent an interrupting frame from ever being drawn.

Sought to draw in a standard serial arrangement as and when bandwidth allows it.

Made further attempts to improve synchronisation and interrelated timing between display and machine update.

Attempted to improve deinterlacing, gave the CRT full control over blend mode, switched back to 2000000Mhz audio.

The penny has finally dropped that I can drive the CPU stuff in a manner completely decoupled from the GPU stuff. For much improved parallelisation.

Made an attempt not to interrupt the display link queue too much when emulation is running slowly.

Fixes: drop any processing backlog, try not to allow an Electron document to close mid-draw, perform a frame grab even if the emulated machine is over-processing, really really don't create a CRT until it's safe.

Fixed: of course I can't rely on the pointer to CVTimeStamp not becoming dangling during a queue jump.

Made sure GL context isn't activated until it's locked.

Added the simplest mechanism to decouple emulation from the display link queue.

Attempted to simplify threading, thereby allowing machines to be constructed within a valid GL context, and started adding appropriate GL syncs. Which all oddly drops everything to a negligible FPS. Investigation will follow.

Renamed CSCathodeRayView to CSOpenGLView as it no longer has any CRT-related responsibilities. It just does the GL and manages a serial dispatch queue.

Ensured all delegate and responder delegate messages occur on the same queue.

Requested multisampling, if available, rather than supersampling.

Switched back down to two samples per pixel. Though one might do it. Need to investigate.

Attempted a switch to the real PAL visible area and to something a bit like a real phosphor decay.

There is now a semi-reasonable amount of screen output again.

Onward with carrying this through to the bitter end, this at least results in all the appropriate knowledge and call-ins occuring at the CRT.

Made an attempt to be more rigorous in display generation on the Electron, to make sure I deal with mid-line changes to/from blank line mode. Even if it turns out that they generate pixels.

Started making first moves towards stripping CSCathodeRayView of its responsibilities. If that can be merely an OpenGL view that presents things, things will be a lot more portable.

Attempted further to improve latency; added view adjustment for non-4:3 output aspect ratios. The 4:3 is currently hardcoded, so further work will be required.

Withdrew soft filtering for now; until the sampling frequency is passed on it's not sufficiently rigorous.
2016-01-12 16:42:16 -05:00

Added some very basic filtering in RGB mode.

Output, at last! Though sync is clearly way off.

Some output! Showing that three lines of solid sync isn't smart. But here it is.

Made an attempt to get RGB output mode up and running, and showing at least a box where pixels would be.
2016-01-09 21:32:56 -05:00

Added the option for the CSCathodeRayView to show only a subsection of the full scan area. Zoomed in a little on the 2600. Put in enough piping to give the Electron sight of its ROMs at least.
2016-01-06 23:14:36 -05:00

Okay, so this is the absolute bare minimum about of refactoring and wiring necessary to get the [unimplemented] Electron machine pumping.
