The zonelists are initialized in 'build_all_zonelists()' called by 'start_kernel()'. But prior to that point there is allot of other code that determines the various zones and holes a key function is free_area_init_node(). But that function will also reference prior initialization in 'setup_arch()' which may take you all the way back to bootloader to kernel interface. Nodes have zones, and zones define what the memory is appropriate for, DMA or lowmem, Normal memory or High memory for 32 bit. For 64 bit there are fewer zones just primarily 32 bit DMA and normal 64 bit. Zones are further divided into free areas of 2^n consecutive pages. Slabs are typically pages carved up into smaller units of allocations. There are several kernel books but outdated, but nevertheless good starting points, just search for 'Kernel Internals' BR, Mario. -----Original Message----- From: linux-newbie-owner@xxxxxxxxxxxxxxx [mailto:linux-newbie-owner@xxxxxxxxxxxxxxx] On Behalf Of ishare Sent: Thursday, March 07, 2013 3:35 PM To: linux-newbie@xxxxxxxxxxxxxxx Subject: memory zone and slab when does the memory zonelist initialized in kernel ? what is the difference between zonelists and slab for memory manage . are there some man docs or sites helpful to understand this ? thanks! -- To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs -- To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
