For playing.

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!

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

256f4a6679 Fixes -invalidate: cancel the dispatch source, don't just suspend it, and wait until that is done. 2020-02-02 21:29:22 -05:00

ee16095863 Withdraws advance_to_next; once it has to cope with simultaneous events it stops being faster than advance.
I could possibly try to deal with those at insertion time, but it'd get messy.

f0a6e0f3d5 Splits out the queue management stuff from queue+action.
Temporarily breaks ST video in the endeavour.

0e29c6b0ab On further reflection, I think events should occur after the running period.
I'm testing this now for sanity in 2/4bpp mode.

65309e60c4 Corrects sequence point generation by allowing for hsync_end != end of line. 2020-01-28 20:38:20 -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.

7e8405e68a Makes 72Hz horizontal sync independently relocatable.
... and moves and shortens it, based on my guesswork as to requirements.

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.
