It also depends on what you consider "a page." For example, if you consider a page a single mapping, depending upon the specific chip, the BATs can be used to create large "pages' ranging in size from 128K to 4G in size. In terms of what are considered to be normal "pages," it's CPU- dependent.

Thanks for the reply. The maximum pages for the processor are taken from which document. Does the ABI for PowerPC mentions the maximum page size ? Which document is that ? Regards Deepak Bhatia This message posted from opensolaris.org

I think what you might have meant to ask is what is the requirement for a executables alignment so that if the memory management on a PowerPC supports larger pages it is guaranteed to be aligned and thus directly able to be paged. Is so, the answer is 64K. This is according to the ABI. This m
