STACK DESCRIPTION
This is a stack of individual graphics projects that have been tested together to generate a proven recipe against different hardware and software configurations. The notes highlight the most important features and bug fixes and also list all known issues.
UPCOMING PLATFORMS
GeminiLake is the newer platform under development. In addition to the new features and fixed bugs noted in the section bellow, GeminiLake brings more fixes and workarounds.
HIGHLIGHTED NEW FEATURES OR FIXED BUGS
Kernel
Support for bigger memory limits in x86 hardware (128PiB of virtual address space, 4PiB of physical address space)
A new unwinder that provides better kernel traces and a smaller kernel size
Cgroups "thread mode" that allows resource distribution across the threads of a group of processes
Support for the zstd compression algorithm has been added to Btrfs and Squashfs
Support for zero-copy of data from user memory to sockets
Better asynchronous buffered I/O support
Support for Heterogeneous Memory Management that will be needed in future GPUs
3D DRIVER - MESA
New features introduced at 17.3.0 and present on 17.3.2 that affect Intel drivers:
ibtxc_dxtn is now integrated into Mesa. GL_EXT_texture_compression_s3tc and GL_ANGLE_texture_compression_dxt are now always enabled on drivers that support them
GL_ARB_indirect_parameters on i965/gen7+
GL_ARB_polygon_offset_clamp on i965, nv50, nvc0, r600, radeonsi, llvmpipe, swr
GL_ARB_transform_feedback_overflow_query on radeonsi
GL_ARB_texture_filter_anisotropic on i965, nv50, nvc0, r600, radeonsi
GL_EXT_memory_object on radeonsi
GL_EXT_memory_object_fd on radeonsi
EGL_ANDROID_native_fence_sync on radeonsi with a future kernel (possibly 4.15)
EGL_IMG_context_priority on i965

MEDIA - LIBVA AND INTEL-VAAPI-DRIVER
LIBVA 2.0.0
No major changes since October 2017
Note libva 2.0.0 is not compatible with the old version of libva, but for most users, what you need to do is to rebuild your VA-API based application against libva 2.0.0.
LIBVA-INTEL-DRIVER-2.0.0
