Simon Ser	3ce2ea9e16	Move allocator stuff into new directory ... Add render/allocator/ and include/render/allocator/ to hold everything allocator-related.	2021-08-25 09:57:20 -04:00
Simon Ser	a38baec1f8	buffer: make enum wlr_buffer_cap public ... Custom backends and renderers need to implement wlr_backend_impl.get_buffer_caps and wlr_renderer_impl.get_render_buffer_caps. They can't if enum wlr_buffer_cap isn't made public.	2021-07-01 16:40:19 -04:00
Simon Ser	38ba5881a0	buffer: replace get_data_ptr with {begin,end}_data_ptr_access ... This new API allows buffer implementations to know when a user is actively accessing the buffer's underlying storage. This is important for the upcoming client-backed wlr_buffer implementation.	2021-06-07 09:22:56 -04:00
Simon Ser	766a24fa77	render/allocator: add wlr_allocator.buffer_caps ... This allows users to know the capabilities of the buffers that will be allocated. The buffer capability is important to know when negotiating buffer formats.	2021-05-31 15:50:13 -04:00
Simon Zeni	a8c91fbac9	render/shm_allocator: make wlr_shm_allocator_create return a wlr_allocator	2021-04-28 20:55:57 +02:00
Simon Ser	24fde77c62	buffer: add format param to get_data_ptr ... Allow wlr_buffer_impl.get_data_ptr to return a format. This allows the Pixman renderer to not care about get_dmabuf/get_shm, and only care about get_data_ptr. This will also help with [1], because client wl_shm buffers can't implement get_shm.

Simon Ser	c6b009ef85	render: introduce shared memory allocator ... It allocates in local main memory via shm_open, and provides a FD to allow sharing with other processes. This is suitable for software rendering under the Wayland and X11 backends.	2021-04-17 09:54:39 +02:00
