Maybe these systems have cache coherent northbridges, which is not the case for the AmigaOne and its "famous" ArticiaS northbridge. > You can try asking on #mklinux.

Guess what > systems usually have this type of bridge? Not 4xx/8xx, that's for sure. Hmm, strange. AFAIK the NOT_COHERENT_CACHE config option is available only for the 4xx and 8xx platforms. Wouldn't the config option depend on CONFIG_6XX too, if there are not cache coherent systems with G4 cpus? At least I could not compile in the dma-mapping.c file without modifying the Kconfig file. > Good luck. Thanks! Gerhard -- Analog-/ISDN-Nutzer sparen mit GMX SmartSurfer bis zu 70%!
