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.

allocator: remove backend parameter in allocator_autocreate_with_drm_fd

2024-02-02T21:36:31+00:00

Since we only use the backend capabilities here we can simply pass them in directly. This allows other locations to create an allocator even if they don't have a backend. They can simply specify the caps they want instead.

render/allocator: log message when GBM is disabled

2023-10-06T09:10:31+00:00

When the backend and renderer would need GBM but it's disabled at compile-time, log a message to make this situation easier to debug.

Avoid using memcpy() to copy structs

2023-08-03T14:40:28+00:00

We can just use a regular assignment instead. This is more type-safe since there is no need to provide the struct size. The remaining memcpy() calls perform array copies or copies from void pointers (which may be unaligned).

Use wl_container_of() instead of casts

2023-07-11T18:16:17+00:00

This slightly improves type safety. The culprits were found with: git grep -E '\([a-z0-9_ ]+ \*\)\W?[a-z]'

Use struct initializers instead of memset()

2023-07-07T15:31:11+00:00

This is a bit more type-safe.

allocator: only use DRM auth if we are master

2023-06-19T19:36:17+00:00

Legacy DRM auth will only work if we are DRM master. Keep using an unauthenticated DRM FD if we are not DRM master. This should be enough for GBM. Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3674

render/pixel-format: add support for block-based formats

2023-05-21T20:28:45+00:00

Some formats like sub-sampled YCbCr use a block of bytes to store the color values for more than one pixel. Update our format table to be able to handle such formats.

build: unify naming for HAVE_* defines

2022-12-06T22:39:45+00:00

We sometimes used HAS_, sometimes polluted the LIBINPUT_ namespace, etc.

render/allocator/gbm: use internal_config

2022-12-06T22:39:45+00:00

Removes a project argument.
