Using Mali with an RTOS

Modern graphics drivers are complicated; there is a lot of work to translate a high-level API like OpenGL ES or OpenCL into the low level hardware commands for the GPU. For example, all drivers include at least one compiler to turn shader code and compute kernels into GPU-specific binaries.

The vast majority of the driver stack which converts API calls into GPU specific commands is in user-space; the kernel part is the minimal part needed for secure operation (e.g. scheduling, MMU and address space management, interrupt control).

Hello Peter, 

I have one query related to RT-linux(RTOS), can we use the same Mali GPU driver comes with Linux DDK or we need different DDK for RT-Linux(RTOS)?
