Add movable allocation system. 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. allow retrieving info about a supervisor allocation 2020-04-14T23:24:54+00:00 Jeff Epler jepler@unpythonic.net 2020-03-25T18:40:48+00:00 urn:sha1:094fe05bdd68332fa617df8a98858e324afa15ec Hook up the terminal based on the first display. 2019-01-31T19:42:14+00:00 Scott Shawcroft scott@tannewt.org 2019-01-26T00:59:18+00:00 urn:sha1:1a1dbef992442682413f6103e36440a26bc2dad7 Polish thanks to Dan's feedback 2019-01-10T19:00:40+00:00 Scott Shawcroft scott@tannewt.org 2019-01-10T19:00:40+00:00 urn:sha1:3dd59c3d5fa59f5bea3acc8e55c4d4a5091e66eb Share memory.c and a bit of polish. 2018-08-02T21:35:46+00:00 Scott Shawcroft scott@tannewt.org 2018-08-02T21:35:46+00:00 urn:sha1:5704bc8c93e36ded3e7dc8e46aa836e7a2acee15 Add basic memory allocation outside Python runtime 2018-07-31T12:18:03+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2018-05-24T20:12:18+00:00 urn:sha1:777542c716e07e78439c3c6bbf442722ebaaecc6 This allows for the heap to fill all space but the stack. It also allows us to designate space for memory outside the runtime for things such as USB descriptors, flash cache and main filename. Fixes #754
