* msm: iommu: Check if device is already attachedStepan Moskovchenko2010-11-301-0/+5
| | | | | | | | | | An IOMMU device can only be attached to one IOMMU domain at any given time. Check whether the device is already attached to a domain before allowing it to be attached to another domain. If so, return busy.

* msm: iommu: Kconfig item for cacheable page tablesStepan Moskovchenko2010-11-301-0/+4
| | | | | | | | | | Add a Kconfig item to allow the IOMMU page tables to be coherent in the L2 cache. This generally reduces IOTLB miss latencies and has been shown to improve multimedia performance.

* msm: iommu: Don't flush page tables if no devices attachedStepan Moskovchenko2010-11-301-6/+9
| | | | | | | | | | | Don't flush the page tables on an IOMMU domain if there are no IOMMU devices attached to the domain. The act of attaching to the domain will cause an implicit flush of those areas if the page tables are configured to not be L2 cacheable.

| | | | | | | | | | | Based on recommendations from chip designers, optimize the Machine ID to translation context mappings for the first 2D core's IOMMU. Remove the "gfx2d0_texv3_smmu" context, as it is no longer needed under the new mapping scheme.

| | | * | | | | ARM: ux500 specific L2 cache codePer Fransson2010-10-261-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The generic version of l2x0_inv_all is only called just after disabling the L2 cache and is surrounded by a spinlock. However, we're not really turning off the L2 cache right now, and the PL310 does not support exclusive accesses (used to implement the spinlock). So, the invalidation needs to be done without the spinlock.

For such buffers the maintainace operations can be speeded up by using the WAY based method.
