drm: re-send HDR metadata blob on modeset (#250) 
After a VT switch or sleep/resume, the kernel discards all DRM property
blobs. restoreAfterVT() rebuilds the atomic commit with the in-memory
HDR metadata, but prepareConnector() skips blob creation because
STATE.committed (the "what changed" bitmask) was cleared after the last
pre-sleep commit.

During a modeset the kernel state is fully reset, so all properties must
be re-sent regardless of the committed flags. Add a data.modeset guard
to bypass the committed check, matching how max_bpc, colorspace, and VRR
are already handled unconditionally.

The existing has_value() check prevents false positives: non-HDR
modesets (resolution changes etc.) don't populate data.hdrMetadata, so
the block is still skipped.

Aquamarine

Aquamarine is a very light linux rendering backend library. It provides basic abstractions for an application to render on a Wayland session (in a window) or a native DRM session.

It is agnostic of the rendering API (Vulkan/OpenGL) and designed to be lightweight, performant, and minimal.

Aquamarine provides no bindings for other languages. It is C++-only.

Stability

Aquamarine depends on the ABI stability of the stdlib implementation of your compiler. Sover bumps will be done only for aquamarine ABI breaks, not stdlib.

Building

cmake --no-warn-unused-cli -DCMAKE_BUILD_TYPE:STRING=Release -DCMAKE_INSTALL_PREFIX:PATH=/usr -S . -B ./build
cmake --build ./build --config Release --target all -j`nproc 2>/dev/null || getconf _NPROCESSORS_CONF`

TODOs

  • Wayland backend
  • DRM backend (DRM / KMS / libinput)
  • Virtual backend (aka. Headless)
  • Hardware plane support
