But just reverting the commit breaks AMD IOMMU so this patch also includes some fixes. The above commit adds new two options to x86 IOMMU generic kernel boot options, fullflush and nofullflush. But such change that affects all the IOMMUs needs more discussion (all IOMMU parties need the chance to discuss it): http://lkml.org/lkml/2008/9/19/106 Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Acked-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | x86 has set_bit_string() that does the exact same thing that set_bit_area() in lib/iommu-helper.c does. This patch exports set_bit_area() in lib/iommu-helper.c as iommu_area_reserve(), converts GART, Calgary, and AMD IOMMU to use it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The alloc_coherent implementation for AMD IOMMU currently uses *dev->dma_mask per default.

| | | * AMD IOMMU: avoid unnecessary low zone allocation in alloc_coherentFUJITA Tomonori2008-09-191-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | x86's common alloc_coherent (dma_alloc_coherent in dma-mapping.h) sets up the gfp flag according to the device dma_mask but AMD IOMMU doesn't need it for devices that the IOMMU can do virtual mappings for. This patch avoids unnecessary low zone allocation.

| | | * AMD IOMMU: don't assign preallocated protection domains to devicesJoerg Roedel2008-09-191-5/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In isolation mode the protection domains for the devices are preallocated and preassigned. This is bad if a device should be passed to a virtualization guest because the IOMMU code does not know if it is in use by a driver. This patch changes the code to assign the device to the preallocated domain only if there are dma mapping requests for it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This function determines if the AMD IOMMU implementation is responsible for a given device. So the DMA layer can get this information from the driver. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The API definition for dma_alloc_coherent states that the bus address has to be aligned to the next power of 2 boundary greater than the allocation size. This is violated by AMD IOMMU so far and this patch fixes it. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
| | | * AMD IOMMU: add branch hints to completion wait checksJoerg Roedel2008-09-191-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds branch hints to the cecks if a completion_wait is necessary. The completion_waits in the mapping paths are unlikly because they will only happen on software implementations of AMD IOMMU which don't exists today or with lazy IO/TLB flushing when the allocator wraps around the address space. With lazy IO/TLB flushing the completion_wait in the unmapping path is unlikely too. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IO/TLB flushing on every unmaping operation is the most expensive part in AMD IOMMU code and not strictly necessary. It is sufficient to do the flush before any entries are reused. This is patch implements lazy IO/TLB flushing which does exactly this.
