Intel developer Vipin Anand on Friday sent out the latest patches for the Intel i915 Linux DRM kernel driver to enable HDR display support.
This HDR support is contingent upon the Gen9 graphics being on a motherboard with a supported LSPCON ASIC. The "Level Shifter and Protocol Converter" chip found integrated into various motherboards/laptops can allow for HDR signaling over HDMI but to now hasn't been supported under Linux.
Intel Gen9 graphics will soon support HDR on Linux
