How can I verify if the memory mapped is coherent on both cores. My memory partitioning is given below
Core Base Address Size Core 0 0x0000,0000 0x1000,0000 --> CONFIG_PHYSICAL_START = bootm_low = Base Address Core 1 0x1000,0000 0x0C00,0000 --> CONFIG_PHYSICAL_START = bootm_low = Base Address Shared Mem 0x1C00,0000 0x0400,0000 Regards, Farrukh Arshad -----Original Message----- From: Scott Wood [mailto:scottw...@freescale.com] Sent: Tuesday, January 03, 2012 10:10 PM To: Arshad, Farrukh Cc: linuxppc-dev@lists.ozlabs.org Subject: Re: Problem in getting shared memory access on P1022RDK On 01/03/2012 03:42 AM, Arshad, Farrukh wrote: > Adding more to it, > > > > When I write from Core 1 on the shared memory region it is visible at > Core 0 and it can read what I have written from Core 1 but when I > write from Core 0 on this shared memory it is not visible on Core 1. Is the memory mapped coherent on both cores? -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
