Frame-Buffer Compression Support For Vintage Intel i865 Graphics Revived
Back in April I wrote about patches for enabling FBC on the Intel 865 chipset nearly two decades after that chipset first shipped. Those patches didn't yet hit the mainline Linux kernel but they were revived again this week.
These patches are for enabling frame-buffer compression support on the Intel Extreme 2 Graphics found with the i865 "Springdale" chipset. Frame-buffer compression can yield performance and power efficiency advantages thanks to the reduced bandwidth. Newer generations of Intel graphics hardware have squared away their FBC support for a while but the i865 era support was overlooked until recent patches improving the state pushed it forward enough where it could finally be enabled by default.
