| | | | | | | | | | | | IPI to a specific CPU by its cpuid. Replace calls to ipi_selected() that constructed a mask for a single CPU with calls to ipi_cpu() instead. This will matter more in the future when we transition from cpumask_t to cpuset_t for CPU masks in which case building a CPU mask is more expensive.

* Add MALLOC_DEBUG_MAXZONES debug malloc(9) option to use multiple umamdf2010-07-281-0/+1
| | | | | | | | | | | | | | | | | | | | | zones for each malloc bucket size. The purpose is to isolate different malloc types into hash classes, so that any buffer overruns or use-after-free will usually only affect memory from malloc types in that hash class. This is purely a debugging tool; by varying the hash function and tracking which hash class was corrupted, the intersection of the hash classes from each instance will point to a single malloc type that is being misused. At this point inspection or memguard(9) can be used to catch the offending code. Add MALLOC_DEBUG_MAXZONES=8 to -current GENERIC configuration files. The suggestion to have this on by default came from Kostik Belousov on -arch. This code is based on work by Ron Steinke at Isilon Systems.

* Very rough first cut at NUMA support for the physical page allocator. Forjhb2010-07-271-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
