[Xen-devel] What "PDX" stands for in xen source code.
Hello, Excuse my very naive questions! What "PDX" stands for in xen source code ? ( as in "PDX_GROUP_COUNT" ) and in this expression "#define PDX_GROUP_COUNT ((1 << L2_PAGETABLE_SHIFT) / (sizeof(*frame_table) & -sizeof(*frame_table)))" , what is the meaning of "(sizeof(*frame_table) & -sizeof(*frame_table))" ? _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
