Module Name: src Committed By: macallan Date: Fri Jul 12 08:43:08 UTC 2024
Modified Files: src/sys/arch/hppa/conf: files.hppa Added Files: src/sys/arch/hppa/dev: hyperfb.c Log Message: first shot at a native driver for HCRX cards this will give you a fully working wsdisplay in 8bit colour living in the overlay planes, X/wsfb will also work. No acceleration or cursor sprite support yet.
