SRM v0.8.0-1

SRM (0.8.0-1)

Bug Fixes

• Fixed buffer allocation issues, particularly on NVIDIA proprietary drivers, which resulted in black textures.
• Corrected framebuffer rendering order in proprietary NVIDIA drivers.
• Resolved partial buffer updates by implementing fences.
• Fixed bug preventing the use of DRM framebuffers with explicit modifiers.

API Additions

• srmDeviceMakeCurrent: Makes the EGL display and context associated with a device current for the calling thread, or creates a new shared one if it doesn't exist.
• srmDeviceSyncWait: Forces pending rendering commands to finish using fences, with glFinish() as a fallback.
• srmBufferGetEGLImage: Retrieves an EGLImage of an SRMBuffer for a specific SRMDevice.
• srmBufferCreateGLTextureWrapper: Creates SRMBuffers from existing OpenGL textures.
• srmConnectorGetFramebufferID: Retrieves the ID of the currently bound OpenGL framebuffer.
• srmConnectorGetContext: Retrieves the EGLContext associated with the connector's rendering thread.
• srmSaveContext: Saves the current EGL context.
• srmRestoreContext: Restores the context previously saved with srmSaveContext().

Internal Changes

• All rendering modes now use renderbuffers instead of EGLSurfaces to prevent buffer ordering issues.
• Fences are used to synchronize buffer updates and access, providing better performance and ensuring no partial updates occur.
• IN_FENCE_FD and sync files are now used when available to wait for rendering commands to finish instead of using glFinish(), improving performance.

Thanks @renhiyama, @kingdomkind, and @Fox2Code for your invaluable help!

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.

-- Eduardo Hopperdietzel [email protected] Wed, 10 Jul 2024 12:44:04 -0400

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.

-- Eduardo Hopperdietzel [email protected] Mon, 08 Jul 2024 00:13:05 -0400

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.
