Name:pcpu_chunk_relocate - put chunk in the appropriate chunk slot*@chunk: chunk of interest*@oslot: the previous slot it was on* This function is called after an allocation or free changed @chunk

Type:void

Name | Describe |
---|---|
pcpu_alloc_area | pcpu_alloc_area - allocates an area from a pcpu_chunk*@chunk: chunk of interest*@alloc_bits: size of request in allocation units*@align: alignment of area (max PAGE_SIZE)*@start: bit_off to start searching* This function takes in a @start offset to begin |
pcpu_free_area | pcpu_free_area - frees the corresponding offset*@chunk: chunk of interest*@off: addr offset into chunk* This function determines the size of an allocation to free using* the boundary bitmap and clears the allocation map. |
pcpu_alloc | pcpu_alloc - the percpu allocator*@size: size of area to allocate in bytes*@align: alignment of area (max PAGE_SIZE)*@reserved: allocate from the reserved chunk if available*@gfp: allocation flags* Allocate percpu area of @size bytes aligned at @align |
pcpu_balance_workfn | Balance work is used to populate or destroy chunks asynchronously. We* try to keep the number of populated free pages between* PCPU_EMPTY_POP_PAGES_LOW and HIGH for atomic allocations and at most one* empty chunk. |
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 |
