Name:memblock_alloc
Proto:static inline void *__init memblock_alloc(phys_addr_t size, phys_addr_t align)
Type:void
Parameter:
Type | Parameter | Name |
---|---|---|
phys_addr_t | size | |
phys_addr_t | align |
373 | Return memblock_alloc_try_nid(size, align, We are using top down, so it is safe to use 0 here , MEMBLOCK_ALLOC_ACCESSIBLE, NUMA_NO_NODE) |

io_apic_init_mappings | |
__register_nosave_region | gister_nosave_region - Register a region of unsaveable memory.* Register a range of page frames the contents of which should not be saved* during hibernation (to be used in the early initialization code). |
setup_log_buf | |
swiotlb_init_with_tbl | |
setup_command_line | We need to store the untouched command line for future reference.* We also need to store the touched command line since the parameter* parsing is performed in place, and we should allow a component to* store reference of name/value for future reference. |
pcpu_alloc_first_chunk | pcpu_alloc_first_chunk - creates chunks that serve the first chunk*@tmp_addr: the start of the region served*@map_size: size of the region served* This is responsible for creating the chunks that serve the first chunk |
pcpu_alloc_alloc_info | pcpu_alloc_alloc_info - allocate percpu allocation info*@nr_groups: the number of groups*@nr_units: the number of units* Allocate ai which is large enough for @nr_groups groups containing*@nr_units units |
pcpu_setup_first_chunk | pcpu_setup_first_chunk - initialize the first percpu chunk*@ai: pcpu_alloc_info describing how to percpu area is shaped*@base_addr: mapped address* Initialize the first percpu chunk which contains the kernel static* percpu area |
alloc_large_system_hash | allocate a large system hash table from bootmem* - it is assumed that the hash table must contain an exact power-of-2* quantity of entries* - limit is the number of hash buckets, not the total allocation size |
