Add a parser for the ACPI SRAT table for amd64 and i386. It sets PCPU(domain) for each CPU and populates a mem_affinity array suitable for the NUMA support in the physical memory allocator. Reviewed by: alc

sys/x86: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Add more fine-grained kernel options for NUMA support. VM_NUMA_ALLOC is used to enable use of domain-aware memory allocation in the virtual memory system. DEVICE_NUMA is used to enable affinity reporting for devices such as bus_get_domain(). MAXMEMDOM must still be set to a value greater than for any NUMA support to be effective. Note that 'cpuset -gd' always works if MAXMEMDOM is enabled and the system supports NUMA. Reviewed by: kib Differential Revision: https://reviews.freebsd.org/D5782

- Remove 'struct vmmeter' from 'struct pcpu', leaving only global vmmeter in place. To do per-cpu stats, convert all fields that previously were maintained in the vmmeters that sit in pcpus to counter(9). - Since some vmmeter stats may be touched at very early stages of boot, before we have set up UMA and we can do counter_u64_alloc(), provide an early counter mechanism: o Leave one spare uint64_t in struct pcpu, named pc_early_dummy_counter. o Point counter(9) fields of vmmeter to pcpu[0].pc_early_dummy_counter, so that at early stages of boot, before counters are allocated we already point to a counter that can be safely written to. o For sparc64 that required a whole dummy pcpu[MAXCPU] array. Further related changes: - Don't include vmmeter.h into pcpu.h. - vm.stats.vm.v_swappgsout and vm.stats.vm.v_swappgsin changed to 64-bit, to match kernel representation. - struct vmmeter hidden under _KERNEL, and only vmstat(1) is an exclusion.

x86/acpica/srat.c: Add API for parsing proximity tables The SLIT and SRAT ACPI tables needs to be parsed on arm64 as well, on systems that use UEFI/ACPI firmware and support NUMA. To do this, we need to move most of the logic of x86/acpica/srat.c to dev/acpica and provide an API that architectures can use to parse and configure ACPI NUMA information. This commit adds the API in srat.c as a first step, without making any functional changes. We will move the common code to sys/dev/acpica as the next step. The functions added are: * int acpi_pxm_init(int ncpus, vm_paddr_t maxphys) - to allocate and initialize data structures used * void acpi_pxm_parse_tables(void) - parse SRAT/SLIT, save the cpu and memory proximity information * void acpi_pxm_set_mem_locality(void) - use the saved data to set memory locality * void acpi_pxm_set_cpu_locality(void) - use the saved data to set cpu locality * void acpi_pxm_free(void) - free data structures allocated by init On arm64, we do not have an cpu APIC id that can be used as index to store CPU data, we need to use the Processor Uid. To help with this, define internal functions cpu_add, cpu_find, cpu_get_info to store and get CPU proximity information.

Add initial memory locality cost awareness to the VM, and include a basic ACPI SLIT table parser. For now this just exports the map via sysctl; it'll eventually be useful to userland when there's more useful NUMA support in -HEAD. * Add an optional mem_locality map; * add a mapping function taking from/to domain and returning the relative cost, or -1 if it's not available; * Add a very basic SLIT parser to x86 ACPI.
