Moving memory contents would not be necessary because displayio can recreate them, but does not hurt. 2020-11-28T16:50:23+00:00 Christian Walther cwalther@gmx.ch 2020-10-11T12:59:33+00:00 urn:sha1:c7404a3ff89c738c002ec63448a58d56330dfcc3 This allows calls to `allocate_memory()` while the VM is running, it will then allocate from the GC heap (unless there is a suitable hole among the supervisor allocations), and when the VM exits and the GC heap is freed, the allocation will be moved to the bottom of the former GC heap and transformed into a proper supervisor allocation. Existing movable allocations will also be moved to defragment the supervisor heap and ensure that the next VM run gets as much memory as possible for the GC heap. By itself this breaks terminalio because it violates the assumption that supervisor_display_move_memory() still has access to an undisturbed heap to copy the tilegrid from. It will work in many cases, but if you're unlucky you will get garbled terminal contents after exiting from the vm run that created the display. This will be fixed in the following commit, which is separate to simplify review. 2020-10-12T22:45:51+00:00 Scott Shawcroft scott@adafruit.com 2020-10-12T22:45:51+00:00 urn:sha1:1eb1434fc968cb05e3cfd69b40434331404ef5df rgbmatrix: update protomatter to 1.0.5 tag 2020-10-12T18:28:20+00:00 Jeff Epler jepler@gmail.com 2020-10-12T18:26:58+00:00 urn:sha1:9696dbfd388aa4c21b686d4566832964c31f8035 If the display is paused, `_PM_swapbuffer_maybe` will never return. So, when brightness is 0, refresh does nothing. This makes it necessary to update the display when unpausing.

The allocated memory was never used, but the GC would have collected it eventually. 2020-09-01T16:00:22+00:00 Jeff Epler jepler@gmail.com 2020-08-31T21:00:41+00:00 urn:sha1:ce603dfebfa9a6ef057110c14c5d5b819eb93069 2020-09-01T16:00:19+00:00 Jeff Epler jepler@gmail.com 2020-09-01T16:00:19+00:00 urn:sha1:dfa90cc11ddf7cd719c448ae9c516bf2b117aa3a 2020-09-01T16:00:07+00:00 Jeff Epler jepler@gmail.com 2020-08-28T16:24:59+00:00 urn:sha1:e01ade3848cf828620ea25ada2b2b829dbe180f3
