SRM v0.7.2-1

SRM (0.7.2-1)

New Environment Variables

• SRM_FORCE_LEGACY_CURSOR: Allows forcing the use of legacy DRM cursor IOCTLs.
• SRM_DISABLE_CURSOR: Allows disabling cursor planes for all drivers.
• SRM_ENABLE_WRITEBACK_CONNECTORS: Allows toggling the writeback DRM client capability.

Internal Changes

• Legacy cursor IOCTLs are now used by default, even when using the atomic API, unless SRM_FORCE_LEGACY_CURSOR is set to 0. This is because legacy IOCTLs are asynchronous and provide a much smoother experience.
• Cursor planes are now disabled by default for NVIDIA proprietary drivers unless SRM_NVIDIA_CURSOR is set to 1. This is because updating cursors occasionally causes screen stuttering.

Dependencies

• Specify the minimum required version of all dependencies.

SRM v0.7.1-1

SRM (0.7.1-1)

Bug Fixes

• Resolved segmentation fault occurring on certain EGL implementations when obtaining a GBM EGLDisplay through eglGetDisplay(). This was fixed by using eglGetPlatformDisplay() instead. Credits to @burgerindividual .

Downloads

• Added link to Fedora package. Credits to @Conan-Kudo .

Dependencies

• Updated EGL dependency to version 1.5 or higher.

SRM v0.7.0-1

SRM (0.7.0-1)

API Additions

• Added srmConnectorSetCustomScanoutBuffer() function to override the primary plane framebuffer for specific frames.
• Introduced srmFormatGetAlphaSubstitute() function to retrieve the translucent or opaque version of DRM formats.

Examples

• Added srm-direct-scanout example.

Internal Changes

• Integrated legacy plane supported formats into SRMPlane with DRM_FORMAT_MOD_INVALID.
• Implemented internal EGL Image creation for CPU buffers allocated through OpenGL.
• Incorporated an internal reference counter to SRMBuffer.

Environment

• Added SRM_DISABLE_CUSTOM_SCANOUT env to enforce disabling srmConnectorSetCustomScanoutBuffer().

SRM v0.6.3-1

SRM (0.6.3-1)

Bug Fixes

• Fallback to using implicit framebuffer modifiers in all rendering modes if drmModeAddFB2WithModifiers() fails. Thanks to @RogerDavenport for reporting the issue.

SRM v0.6.2-1

SRM (0.6.2-1)

Bug Fixes

• Fixed incorrect default linear gamma table calculation in atomic API.
• Added mutex to prevent racing conditions with external threads when updating the atomic changes flags.

SRM v0.6.1-1

SRM (0.6.1-1)

Performance

• New PRIME rendering mode introduced to enhance performance on multi-GPU setups with limited common DMA formats/modifiers.
• Integrated GPUs are now designated as the default allocator device (primary device), promoting lower power consumption and improved performance.

Bug Fixes

• Added small validation tests to ensure proper selection of main-memory buffer allocation APIs, preventing texture glitches on drivers that do not fully support GBM APIs.

Environment

• All rendering modes now default to double buffering, with optional support for triple buffering. The single buffering option has been deprecated.

Examples

• Added link to example that uses Skia as renderer.

SRM v0.6.0-1

SRM (0.6.0-1)

New APIs

• Introduced srmConnectorSetContentType() and srmConnectorGetContentType() functions to optimize display hardware for the type of content being displayed.

Bug Fixes

• Ensured connector properties are re-synchronized after session switching to resolve issues with cursor visibility, position, and other related errors.

Internal Changes

• Replaced custom connector name IDs with connector_type_id (e.g., HDMI-A-1, HDMI-A-2, etc.).
• Maintained a copy of gamma tables in the legacy API to ensure proper restoration during session switching.

SRM v0.5.7-1

SRM (0.5.7-1)

Bug Fixes

• Fix bug when using the atomic API that prevents cursor planes from being displayed when the first commit fails.

SRM v0.5.6-2

SRM (0.5.6-2)

Building

• Add DRM headers dependency to all examples to resolve issues locating the drm_fourcc.h header, thanks to @EBADBEEF.
• Remove unnecessary header include checks in meson.build.

SRM v0.5.6-1

SRM (0.5.6-1)

Bug Fixes

• Implemented GL and EGL extension checks to prevent SRMBuffers creation when conditions to use them are not met.
• Replaced the device used to retrieve the OpenGL texture ID of a framebuffer used in DUMB mode, resolving segfaults with nvidia-drm drivers. Special thanks to @dranull and @JaanDev for reporting and testing.

Environment

• Added the SRM_DEVICES_BLACKLIST environment variable for disabling specific DRM devices.
• By default, disabled cursor planes on Nvidia proprietary drivers, which were causing significant FPS drops when updated. Also, added the SRM_NVIDIA_CURSOR environment variable to enable it if desired.

Documentation

• Added Nvidia drivers section on the Environment page with recommended configurations.
