C++ (Cpp) sync_icache_aliases Examples

Example #1

File: flush.c Project: 0x7f454c46/linux

static void flush_ptrace_access(struct vm_area_struct *vma, struct page *page,
				unsigned long uaddr, void *kaddr,
				unsigned long len)
{
	if (vma->vm_flags & VM_EXEC)
		sync_icache_aliases(kaddr, len);
}

Example #2

File: flush.c Project: 0x7f454c46/linux

void __sync_icache_dcache(pte_t pte)
{
	struct page *page = pte_page(pte);

	if (!test_and_set_bit(PG_dcache_clean, &page->flags))
		sync_icache_aliases(page_address(page),
				    PAGE_SIZE << compound_order(page));
}

Example #3

File: flush.c Project: 01org/thunderbolt-software-kernel-tree

void __sync_icache_dcache(pte_t pte, unsigned long addr)
{
	struct page *page = pte_page(pte);
