v0.2.0 Release: 0.2.0
libliftoff v0.2.0 This is the second libliftoff release. Major changes: - All functions which can fail now return zero on success, and a negative error number on failure. This allows callers to get more information about failures. - liftoff_output_needs_composition and liftoff_layer_needs_composition have been introduced. - libliftoff has migrated to gitlab.freedesktop.org. Full commit history below. Simon Ser (41): Make liftoff_output_apply return an int Make liftoff_device_register_all_planes return an int Stop including stdbool.h from libliftoff.h Make liftoff_layer_set_property return negative errno build: bump version to 0.2.0 Add needs_composition APIs Improve prop value pretty-printing in output_log_layers Make fp16_to_double static Log when no layer has been a plane Log number of candidate planes test: make sure NDEBUG is not defined Log number of layers in output_log_layers Log when a test-only commit fails Print alloc debug logs as a tree Zero-initialize alloc_step and alloc_result Improve alloc debug logging test: introduce liftoff_mock_require_primary_plane Document why the primary plane is a special case build: turn on additional warnings Add newline after function return type Remove test/include/ Log number of atomic test-only commits test/test_prop: add unmatched test case Make plane_get_property static ENOSPC is not fatal for test-only commits Migrate to gitlab.freedesktop.org ci: drop py3-setuptools from Alpine packages ci: add .gitlab-ci.yml Check layers zpos over the primary plane test/alloc: add zpos-2x-reverse test/alloc: add zpos-2x-fail test/alloc: make test data const test/alloc: check test_layer.compat length test/alloc: replace test_layer.zpos with test_prop test/alloc: pass full test_case to run_test test/alloc: drop test_needs_composition logic test/alloc: move zero-fb-id-fail to test data test/alloc: rename composition-zero-fb-id to composition-no-props Ignore invisible layers in layer_intersects test/alloc: add zpos-3x-zero-fb-id test/alloc: add zpos-3x-zero-alpha -
v0.1.0 Release: 0.1.0
libliftoff v0.1.0 This is the first release of libliftoff. libliftoff is still an experimental library, no guarantees are made regarding the stability of its API.
