Detailed Description

Memory handling utility functions used throughout the code.

Function Documentation

page_aligned_alloc()

auto util::memory::page_aligned_alloc ( size_t size ) -> void *

nodiscard

Allocates memory aligned by page size, with a minimum alignment of 4096 bytes. Memory allocated by this function must be freed by calling page_aligned_free(). Returns nullptr if the memory could not be allocated.

page_aligned_free()

page_aligned_free()

void util::memory::page_aligned_free

(

void *

mem

)

Frees page-aligned memory allocated by page_aligned_alloc(). This is a no-op if mem is nullptr.

prefetch()

void util::memory::prefetch

(

const void *

mem

)

Hints the CPU to prefetch the page that the given memory address is on. This function is nonblocking, and may be a no-op depending on the target platform.
