When I looked at dmesg, the memory ZONES were divided as below 768MB for ZONE_DMA 256MB for ZONE_HIGHMEM ZONE_NORMAL is not present. Now what does this mean? Is that kernel space entirely mapped to ZONE_DMA? Does user process get only 256MB of physical memory? I am pretty much confused about these zones. Is this particular to only PPC architecture? Kindly clarify Thanks in advance Heramba -- To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
