https://bugzilla.novell.com/show_bug.cgi?id=202133 ------- Comment #35 from matt@genesi-usa.com 2006-10-20 10:17 MST ------- For ppc64 - at least on PowerMac G5's and anything using IBM system controllers (Maple, p185, JS20, JS21, dunno about POWER or anything without the Power Architecture 32/64-bridge) I think memory has been mapped traditionally such that you have 2GB of real memory before PCI space, and then PCI space literally sits before the 4GB barrier minus 256MB. http://www-306.ibm.com/chips/techlib/techlib.nsf/techdocs/B2BBA0230B9B9BF487... Section 12.1 gives the memory map. So a 32-bit physical addresses for PCI/PCIe/whatever will Just Work (tm) for this platform. I could be wrong, like I said, about POWER5 or POWER6 or anything that does not implement the magic 32-bit bridge specification, but I am sure they all do :) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
