C++ (Cpp) GHES_IOREMAP_IRQ_PAGE Examples

Example #1

File: ghes.c Project: AnadoluPanteri/kernel-plus-harmattan

static void ghes_iounmap_irq(void __iomem *vaddr_ptr)
{
	unsigned long vaddr = (unsigned long __force)vaddr_ptr;
	void *base = ghes_ioremap_area->addr;

	BUG_ON(vaddr != (unsigned long)GHES_IOREMAP_IRQ_PAGE(base));
	unmap_kernel_range_noflush(vaddr, PAGE_SIZE);
	__flush_tlb_one(vaddr);
}

Example #2

File: ghes.c Project: AnadoluPanteri/kernel-plus-harmattan

static void __iomem *ghes_ioremap_pfn_irq(u64 pfn)
{
	unsigned long vaddr;

	vaddr = (unsigned long)GHES_IOREMAP_IRQ_PAGE(ghes_ioremap_area->addr);
	ioremap_page_range(vaddr, vaddr + PAGE_SIZE,
			   pfn << PAGE_SHIFT, PAGE_KERNEL);

	return (void __iomem *)vaddr;
}

Example #3
