Changelog: ============ - Relax sanitization checks for "morx"subtables to fix broken AAT shaping of macOS 15.0 version of GeezaPro. - Unicode 16.0.0 support. - Various documentation fixes. - Various build fixes. - Add API to allow HarfBuzz client to set what glyph to use when a Unicode Variation Selector is not supported by the font, which would allow the client to customize what happens in this case, by using a different font for example. - Add a callback to for "hb_face_t"for getting the list of table tags. This is now used to make calling "hb_face_get_table_tags()"work on a faces created by "hb_face_create_for_tables()"(e.g. faces returned by "hb_subset_or_fail()"). - CGJ and Mongolian Variation Selectors are now ignored during glyph positioning, previously they would block both glyph substitution and positioning across them. - Support cairo script as an output format for "hb-view"command line tool. - Drop an optimization that would cause HarfBuzz not apply pair positioning lookup subtables under certain circumstances, for compatibility with other implementations that do apply these subtables. - Subsetting will now fail if source font has no glyphs, so feeding the subsetter invalid data will not silently return an empty face. - If after partially instancing a font no variation data is left (the instance is fully static), don't consider this a failure. - Workaround a Firefox bug in displaying SVGs generated be "hb-view"command line tool under certain circumstances. - Fix bug in macroman mapping for "cmap"table. - Fix difference shaping output when HarfBuzz is built with with "HB_NO_OT_RULESETS_FAST_PATH"enabled. - Various subsetting and instancing fixes. - Various fuzzing fixes. - Add "with_libstdcxx"meson build option. - New API: HB_SCRIPT_GARAY HB_SCRIPT_GURUNG_KHEMA HB_SCRIPT_KIRAT_RAI HB_SCRIPT_OL_ONAL HB_SCRIPT_SUNUWAR HB_SCRIPT_TODHRI HB_SCRIPT_TULU_TIGALARI hb_buffer_set_not_found_variation_selector_glyph() hb_buffer_get_not_found_variation_selector_glyph() hb_get_table_tags_func_t hb_face_set_get_table_tags_func() (From OE-Core rev: 832272063fe58577b9d959d7dbd4f92d9c22670e) Signed-off-by: Wang Mingyu <wangmy@fujitsu.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
Poky
Poky is an integration of various components to form a pre-packaged build system and development environment which is used as a development and validation tool by the Yocto Project. It features support for building customised embedded style device images and custom containers. There are reference demo images ranging from X11/GTK+ to Weston, commandline and more. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK suitable for IDE integration.
Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of BSP layers which extend the systems capabilities in a modular way. Many layers are available and can be found through the layer index.
As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation, the 'meta-yocto' layer which has configuration and hardware support components. These components are all part of the Yocto Project and OpenEmbedded ecosystems.
The Yocto Project has extensive documentation about the system including a reference manual which can be found at https://docs.yoctoproject.org/
OpenEmbedded is the build architecture used by Poky and the Yocto project. For information about OpenEmbedded, see the OpenEmbedded website.

Where to Send Patches
As Poky is an integration repository (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:
OpenEmbedded-Core (files in meta/, meta-selftest/, meta-skeleton/, scripts/):
- Git repository: https://git.openembedded.org/openembedded-core/
- Mailing list: openembedded-core@lists.openembedded.org
BitBake (files in bitbake/):
- Git repository: https://git.openembedded.org/bitbake/
- Mailing list: bitbake-devel@lists.openembedded.org
Documentation (files in documentation/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
- Mailing list: docs@lists.yoctoproject.org
meta-yocto (files in meta-poky/, meta-yocto-bsp/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto
- Mailing list: poky@lists.yoctoproject.org
If in doubt, check the openembedded-core git repository for the content you intend to modify as most files are from there unless clearly one of the above categories. Before sending, be sure the patches apply cleanly to the current git repository branch in question.
