Hiroshi DOYU 69d3a84a64 omap iommu: simple virtual address space management ... This patch provides a device drivers, which has a omap iommu, with address mapping APIs between device virtual address(iommu), physical address and MPU virtual address. There are 4 possible patterns for iommu virtual address(iova/da) mapping. |iova/ mapping iommu_ page | da pa va (d)-(p)-(v) function type --------------------------------------------------------------------------- 1 | c c c 1 - 1 - 1 _kmap() / _kunmap() s 2 | c c,a c 1 - 1 - 1 _kmalloc()/ _kfree() s 3 | c d c 1 - n - 1 _vmap() / _vunmap() s 4 | c d,a c 1 - n - 1 _vmalloc()/ _vfree() n* 'iova': device iommu virtual address 'da': alias of 'iova' 'pa': physical address 'va': mpu virtual address 'c': contiguous memory area 'd': dicontiguous memory area 'a': anonymous memory allocation '()': optional feature 'n': a normal page(4KB) size is used. 's': multiple iommu superpage(16MB, 1MB, 64KB, 4KB) size is used. '*': not yet, but feasible. Signed-off-by: Hiroshi DOYU <Hiroshi.DOYU@nokia.com>		2009-05-19 08:23:49 +03:00
