Phoronix reports Intel's ubiquitous Gen9 graphics, which has been used for all pre-Ice Lake chips since 2015, will soon get HDR support on the Linux platform. The site says Intel's Linux update will add HDR support for Kaby Lake or newer chips, on motherboards with an LSPCON chip from Megachips America (MCA). Uers with a LSPCON chip from Parade Technologies, which is used on some motherboards, are out of luck.
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.
