Some drivers redefine MAXPHYS to be 512KiB. Some use their own local MAXPHYS which is usually 128KiB. Some look at MAXPHYS to figure out other things; the details escape me. There's one driver which actually uses 100*MAXPHYS for something, but I didn't check the details. Lots of them were non-CAM drivers AFAICT. -- Gary JennejohnReceived on Mon Mar 22 2010 - 10:40:22 UTC
