My understanding is that the MMU code is different and unsupported. Anyone ever try it or back-port it to a strictly 32-bit machine?</P><P></P><P>Thanks,</P><P>Paul</P></BODY></HTML> Thu, 27 Sep 2012 16:23:13 GMT https://community.nxp.com/t5/P-Series/HugeTLBFS/m-p/198225#M76 genuap 2012-09-27T16:23:13Z Re: HugeTLBFS https://community.nxp.com/t5/P-Series/HugeTLBFS/m-p/198226#M77 <HTML><HEAD></HEAD><BODY><P>It is not supported if large physical address support is turned off.&nbsp; There should be no problem enabling large physical address support on any mpc85xx/QorIQ chip, even if the chip doesn't support 36-bit physical.&nbsp; It's about Linux's internal data structures, not the hardware.</P></BODY></HTML> Thu, 27 Sep 2012 17:09:57 GMT https://community.nxp.com/t5/P-Series/HugeTLBFS/m-p/198226#M77 scottwood 2012-09-27T17:09:57Z
