Change Details

Introduce macro for PTE_TO_PA, setting the groundwork for future support of various Arm VMSA extensions. For extensions such a 52-bit VA/PA, this macro will need to be expanded to allow more complex conversions between PTE and PA. Currently PTE_TO_PA is achieved by masking off the upper and lower attributes. Retain this behaviour but replace all instances with the new macro instead. Sponsored by: Arm Ltd

Introduce macro for PTE_TO_PA, setting the groundwork for future support of various Arm VMSA extensions. For extensions such as 52-bit VA/PA (FEAT_LPA2), the representation of an address between a PTE and PA are not equivalent. This macro will allow converting between the different representations. Currently going from PTE to PA is achieved by masking off the upper and lower attributes. Retain this behaviour but replace all instances with the new macro instead. Sponsored by: Arm Ltd
