dac217c98c Defers starting the macOS audio queue, and attempts to restart it upon packet loss. 
Hopefully forever to vanish permanent audio loss?

b76a5870b3 Moves drawing into the next timer tick after retrace if sync locked. 
... which should mean it occurs within 1/600th of a second of announced retrace, which I assume always will be less than the retrace period. So: does the frame buffer update during retrace.

This should completely eliminate tearing for machines that can be synced to the native output rate.
 2020-02-08 18:07:13 -05:00
Thomas Harte
7c0f3bb237 Gets to slightly adjusting execution speed and matching up respective vertical syncs. 
I probably still need to move the ->draw inline.
 2020-02-08 18:01:48 -05:00

f615d096ca Switch to obtaining refresh periods ephemerally. 
Which simplifies the necessary delegate protocol.

cf9729c74f Takes a first shot at running OpenGL work throughout a frame. 
Rather than en masse at the end. But it seems I've been lazy with my threading. Work to do!
 2020-02-03 21:58:29 -05:00

0f2783075f Moves responsibility for timed updates to CSMachine, which gives the CSHighPrecisionTimer a shot. 2020-02-02 21:39:20 -05:00

Thomas Harte
5c4623e9f7 Adds a sequence-point test for 72Hz mode. 
Which immediately appears to trigger the hsync issue I'm also seeing in manual testing.

52e49439a6 Recreates display link upon a screen change. 
Different screens may have different refresh rates, and I can find no guarantees about how Apple handles that.
 2020-01-26 23:23:33 -05:00
Thomas Harte
6bcdd3177d Ensures that a change of screen issues a reshape. Just in case. 
Thereby resolves display mis-sizing when dragging from a Retina display to a regular one, or vice versa.
 2020-01-26 18:04:25 -05:00

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

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.
 2020-01-23 22:57:51 -05:00
Thomas Harte
7bac439e95 Adds, and comments out, a useful temporary piece of debugging logging. 2020-01-23 22:14:22 -05:00

3c6a00dc3c Breaks a potential deadlock. 2020-01-22 22:10:20 -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.

3aa2c297a2 Adds feedback to the best-effort updater; enables the Cocoa port for audio event requests. 2020-01-20 17:38:25 -05:00
Thomas Harte
290db67f09 Adds a forward route for event flags. Doesn't yet account for extra time expended. 2020-01-20 17:09:01 -05:00
Thomas Harte
4de121142b Adds a flags parameter to the BestEffortUpdater delegate. 
On the Cocoa side, cuts Swift out of the update loop, as that seems merely to add code.
 2020-01-20 16:21:53 -05:00
Thomas Harte
3c760e585a Switches to accepting a bit mask of events to run_until. 2020-01-20 16:08:21 -05:00

1b4b6b0aee Renames: NumberTheory -> Numeric. 2020-01-19 23:14:35 -05:00
Thomas Harte
5391a699a4 Adds the ability for a PCMSegment to maintain 'fuzzy' (i.e. random) bits. Implements an LFSR for bit generation. 
I'm not necessarily happy with the idea of just shoving in a [pseudo-]random number generator in rather than emulating the proper process underneath, but for now I throw my arms up.
 2020-01-19 20:09:11 -05:00

Thomas Harte
91fae86e73 Factors out paging, implements a bit more of the BD500. 
That is, enough seemingly fully to work, if I force the drive to report ready.

Also finally implements KeyNMI.
 2020-01-05 21:57:33 -05:00
Thomas Harte
9f30be1c13 Attempts to implement most of a Jasmin disk interface. 
With one obvious omission: there's no way to start it? The real interface had a dedicated button, but I don't yet know what that button did. Research needed.

c1bae49a92 Standardises on read and write for bus accesses. 
Logic being: name these things for the bus action they model, not the effect they have.
 2020-01-05 13:40:02 -05:00

 2019-06-04 21:41:09 -04:00
Thomas Harte

 2019-06-01 19:31:32 -04:00
Thomas Harte
6d985866ee All proper inputs are now provided to the audio generator.

 2019-04-28 23:11:49 -04:00
Thomas Harte
0298b1b3b7 Implements LINK and UNLINK. 
Also starts excluding opcodes that I can't determine the mapping of from the list of those tested against.

Due to those two things together, the latter incomplete: 627 opcodes outstanding. But only STOP and MOVEP remain on my list of things to implement prior to exceptions.
 2019-04-28 17:12:31 -04:00
