b514756272 Adds the option to run machines at a multiple of their real speeds. 
Exposed to SDL users only, for now.

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.

ba516387ba In all these instances, final => override. So no need to repeat myself. 2020-01-23 22:35:39 -05:00

6802318784 Removes audio_queue_.flush() calls; I don't think I really need to block. At least, not usually. 2020-01-23 20:13:16 -05:00

beefb70f75 Adds vertical sync as something that can be run_until. 2020-01-22 22:20:56 -05:00

8404409c0d Causes the Atari 2600 to obey normal flush semantics. 
This stuff is going to become more important with run_until.

9d97a294a7 Corrects the TMS' get_scaled_scan_status. 
I think all platforms are now returning credible numbers.

56448373ae Splits one line into two, for the benefit of step debugging. 2020-01-22 19:32:23 -05:00

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.

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.

Thomas Harte
3c760e585a Switches to accepting a bit mask of events to run_until. 2020-01-20 16:08:21 -05:00

8adb2283b5 Rewrites the best-effort updater to try to get better thread affinity. 2020-01-20 13:38:46 -05:00
Thomas Harte
cb61e84868 Starts building out higher-level run_until functionality. 
Specifically: you can now run until the next set of speaker samples has been delivered.
 2020-01-20 12:12:23 -05:00
Thomas Harte
8349005c4b Adds CRTMachine::run_until, which will run until a condition is true. 
I want to get to being able to say "run until the beam is 60% of the way down", "run until a new packet of audio has been delivered", etc.

 2020-01-19 21:48:07 -05:00

c2bd5be51a This seems to be the proper interpretation of speeds? 2020-01-19 20:42:51 -05:00

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.
