The Linux x64 (AMD64/EM64T) Display Driver 550.135 has been enhanced to provide direct framebuffer access for Wayland compositors on more recent kernels. The driver has been enhanced to support the enumeration of modes on hotplugevents via the DRM fbdev API, updates have been made to the kernel module build process to incorporate CONFIG_CC_VERSION_TEXT, and a bug has been resolved.
Linux x64 (AMD64/EM64T) Display Driver 550.135 | Linux 64-bit
Release Highlights
In Linux kernel 6.11, drm_fbdev_generic was renamed to drm_fbdev_ttm.Use drm_fbdev_ttm when present to keep supporting direct framebufferaccess needed for Wayland compositors to present content on newerkernels.
In linux-next commit 446d0f4849b1, output_poll_changed is removedfrom struct drm_mode_config_funcs. Do not implement the functionpointer member when not present to ensure the driver can compile withnewer kernels. The driver now supports enumerating modes on hotplugevents through the DRM fbdev API.
Updated the kernel module build process to use CONFIG_CC_VERSION_TEXTfrom the Linux kernel's Kconfig to detect the compiler used to buildthe kernel. This may help select the correct compiler on systems wherethe kernel was built with a compiler other than the default one.
Fixed a bug that prevented kernel modules linked using precompiledkernel interface files from loading on recent Debian systems.
