2017Q2 Intel Graphics Stack Recipe
Download Links
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.
The 2017Q2 highlights are:
Frame-buffer compression (FBC) has been enabled for SkyLake and newer platforms which will reduce power consumption at the same time lowering memory bandwidth in screen refreshes.
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
Adding audio to Display Port (DP) Multi-stream Transport Capabilities (MST) displays.
FBC enabled by default for SkyLake and newer platforms.
GeminiLake graphics support for development platform.
