| H A D | vmparam.h | diff 210550 Tue Jul 27 18:34:40 MDT 2010 jhb Very rough first cut at NUMA support for the physical page allocator. For now it uses a very dumb first-touch allocation policy. This will change in the future. - Each architecture indicates the maximum number of supported memory domains via a new VM_NDOMAIN parameter in <machine/vmparam.h>. - Each cpu now has a PCPU_GET(domain) member to indicate the memory domain a CPU belongs to. Domain values are dense and numbered from 0. - When a platform supports multiple domains, the default freelist (VM_FREELIST_DEFAULT) is split up into N freelists, one for each domain. The MD code is required to populate an array of mem_affinity structures. Each entry in the array defines a range of memory (start and end) and a domain for the range. Multiple entries may be present for a single domain. The list is terminated by an entry where all fields are zero. This array of structures is used to split up phys_avail[] regions that fall in VM_FREELIST_DEFAULT into per-domain freelists. - Each memory domain has a separate lookup-array of freelists that is used when fulfulling a physical memory allocation. Right now the per-domain freelists are listed in a round-robin order for each domain. In the future a table such as the ACPI SLIT table may be used to order the per-domain lookup lists based on the penalty for each memory domain relative to a specific domain. The lookup lists may be examined via a new vm.phys.lookup_lists sysctl. - The first-touch policy is implemented by using PCPU_GET(domain) to pick a lookup list when allocating memory.
