swiotlb: remove unnecessary swiotlb_sync_single_range_*

2010-05-27T16:12:52+00:00

swiotlb_sync_single_range_for_cpu and swiotlb_sync_single_range_for_device
are unnecessary because swiotlb_sync_single_for_cpu and
swiotlb_sync_single_for_device can be used instead.

swiotlb: Defer swiotlb init printing, export swiotlb_print_info()

2009-11-10T11:32:00+00:00

This enables us to avoid printing swiotlb memory info when we
initialize swiotlb. After swiotlb initialization, we could find
that we don't need swiotlb.

This patch removes the code to print swiotlb memory info in
swiotlb_init() and exports the function to do that.

swiotlb: Add swiotlb_free() function

2009-11-10T11:31:52+00:00

swiotlb_free() function frees all allocated memory for swiotlb.

We need to initialize swiotlb before IOMMU initialization (x86
and powerpc needs to allocate memory from bootmem allocator). If
IOMMU initialization is successful, we need to free swiotlb
resource (don't want to waste 64MB).

swiotlb: use phys_to_dma and dma_to_phys

2009-07-28T05:19:20+00:00

This converts swiotlb to use phys_to_dma and dma_to_phys instead of
swiotlb_phys_to_bus() and swiotlb_bus_to_phys().

swiotlb_phys_to_bus() and swiotlb_bus_to_phys() are not necessary so
this patch also removes them.

swiotlb: change swiotlb_bus_to[phys,virt] prototypes

2009-04-08T14:18:38+00:00

Add a hwdev argument that is needed on some architectures
in order to access a per-device offset that is taken into
account when producing a physical address (also needed to
get from bus address to virtual address because the physical
address is an intermediate step).

Also make swiotlb_bus_to_virt weak so architectures can
override it.

swiotlb: range_needs_mapping should take a physical address.

2009-01-11T03:54:34+00:00

The swiotlb_arch_range_needs_mapping() hook should take a physical
address rather than a virtual address in order to support highmem pages.
