Simon Ser	58d4cfaca3	render/allocator/drm_dumb: drop finish_buffer() ... Simplify things a bit.	2 years ago
Simon Ser	c659792d7b	render/allocator/drm_dumb: fix error handling ... In the CREATE_DUMB error code-path, we'd only free() the buffer, however it's already inserted in the alloc->buffers list at this point. Instead, make sure finish_buffer() is safe to call (by populating drm_fd) and call that function.	2 years ago
Simon Ser	3e7ea8715b	render/allocator/drm_dumb: get format info before allocating ... Simplifies error handling a bit.	2 years ago
Simon Ser	d81f68d2b4	render/allocator/drm_dumb: check modifier list ... Check that the modifier list passed as input contains either INVALID or LINEAR. We don't support others.	2 years ago
Simon Ser	5ef8a18a29	render/allocator/drm_dumb: advertise LINEAR instead of INVALID modifier ... INVALID means that the modifier is implicit. However dumb buffers are guaranteed to be LINEAR, so let's just advertise this. Fixes cursors with the DRM backend: cursor planes usually only support LINEAR.	2 years ago
Simon Ser	39b68ea47a	buffer: extract interface to separate header ... Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3389	3 years ago
Simon Zeni	02a1ae169e	render/allocator: make wlr_allocator part of the public API	3 years ago
Simon Ser	4e7a8707cc	buffer: add data_ptr access flags ... This allows callers to specify the operations they'll perform on the returned data pointer. The motivations for this are: - The upcoming Linux MAP_NOSIGBUS flag may only be usable on read-only mappings. - gbm_bo_map with GBM_BO_TRANSFER_READ hurts performance.	3 years ago
Simon Ser	d9d8fc1ab9	render/allocator: re-open GBM FD ... Using the same DRM file description for the DRM backend and for the GBM allocator will result in GEM handle ref'counting issues [1]. Re-open the DRM FD to fix these issues. [1]: https://gitlab.freedesktop.org/mesa/drm/-/merge_requests/110	3 years ago
Simon Ser	3ce2ea9e16	Move allocator stuff into new directory ... Add render/allocator/ and include/render/allocator/ to hold everything allocator-related.	3 years ago
