Abstract
The present disclosure relates to methods and apparatus for graphics processing. Aspects of the disclosure are directed to a method for accessing secure memory ranges. In some examples, the method includes reserving a first memory address range within a 32-bit address range for non-secure memory. In some examples, the method includes reserving a second memory address range within a 64-bit address range and outside the 32-bit address range for secure memory. In some examples, the method includes receiving, by a 64-bit kernel, a first command from a 32-bit application for accessing the secure memory. In some examples, the method includes preparing, by the 64-bit kernel, a 64-bit memory access command based on the first command. In some examples, the method includes transmitting, by the 64-bit kernel, the 64-bit memory access command to a graphics processing unit (GPU).
