scene: ignore duplicate wlr_scene_output_layout_add_output() calls

2024-02-20T10:04:46+00:00

An assert was added in [1] to avoid tracking the same output multiple times. However, this is cumbersome for compositors [2]: they need to add a special check for this. Additionally, this is inconsistent with wlr_output_layout_add(). [1]: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/4380 [2]: https://github.com/cage-kiosk/cage/pull/315

Define _POSIX_C_SOURCE globally

2024-02-15T14:41:12+00:00

Stop trying to maintain a per-file _POSIX_C_SOURCE. Instead, require POSIX.1-2008 globally. A lot of core source files depend on that already. Some care must be taken on a few select files where we need a bit more than POSIX. Some files need XSI extensions (_XOPEN_SOURCE) and some files need BSD extensions (_DEFAULT_SOURCE). In both cases, these feature test macros imply _POSIX_C_SOURCE. Make sure to not define both these macros and _POSIX_C_SOURCE explicitly to avoid POSIX requirement conflicts (e.g. _POSIX_C_SOURCE says POSIX.1-2001 but _XOPEN_SOURCE says POSIX.1-2008). Additionally, there is one special case in render/vulkan/vulkan.c. That file needs major()/minor(), and these are system-specific. On FreeBSD, _POSIX_C_SOURCE hides system-specific symbols so we need to make sure it's not defined for this file. On Linux, we can explicitly include and ensure that apart from symbols defined there the file only uses POSIX toys.

Add more POSIX compliance macros to fix uClibc support

2024-02-12T16:41:45+00:00

- Add POSIX 1993.09 compliance macro in source files that use "struct timespec"; - Add POSIX 2001.12 compliance macro in source files that use "struct sigaction" and the SA_SIGINFO macro, or the fchmod() function; - Add POSIX 2008.09 compliance macro in source files that use the getline() function. These compliance macros are enough for wlroots to compile with the git-master version of uClibc-ng. Signed-off-by: Paul Cercueil

scene: release shm buffers once uploaded

2024-01-27T12:21:54+00:00

Once a shm buffer is uploaded there's no reason for wlr_scene_buffer to keep it locked any further. Allow the compositor to re-use it.

scene: drop wlr_scene_set_presentation()

2023-12-27T12:41:20+00:00

presentation-time: drop wlr_presentation arg

2023-12-27T12:41:01+00:00

There can only be a single presentation-time global advertised to clients, this it's unnecessary to pass around the wlr_presentation pointer.

wlr_scene: fix transformed outputs backend damage clearing

2023-12-04T12:06:35+00:00

When we cleared the pending backend damage when the output committed, we would not take into account the output transform. It's easiest to fix this by just changing pending_commit_damage to always have transformed coordinates.

wlr_scene: Apply output damage once

2023-12-04T11:58:35+00:00

We would apply it twice if we failed direct scanout. Once when we attempt direct scanout and again when we composite.

wlr_scene: Don't damage whole damage ring when exiting direct scanout

2023-12-03T05:29:05+00:00

Direct scanout damage will just accumulate on the damage ring while in direct scanout and properly damage when we exit anyway. On the flip side since we now manage backend damage submission ourselves, this won't break that either.

wlr_scene: Use wlr_damage_ring_rotate_buffer()

2023-12-03T05:29:05+00:00

Compositors who use _build_state are no longer required to call damage_ring_rotate themselves. This is a minor breaking change.
