Lioncash c13fbe6a41 video_core/memory_manager: Make Read() a const qualified member function 
Given this doesn't actually alter internal state, this can be made a
const member function.

Lioncash 76ef6e5c2b video_core/memory_manager: Make ReadBlock() a const qualifier member function 
Now, since we have a const qualified variant of GetPointer(), we can put
it to use in ReadBlock() to retrieve the source pointer that is passed
into memcpy.

Now block reading may be done from a const context.

Lioncash 34510bcda8 video_core/memory_manager: Add a const qualified variant of GetPointer() 
Allows retrieving read-only pointers from a const context externally.
 2019-04-05 20:25:28 -04:00
Lioncash 085b388a7a video_core/memory_manager: Make FindFreeRegion() a const member function 
This doesn't modify internal state, so it can be made a const member
function.

Lioncash 9dec087fca video_core/memory_manager: Make GpuToCpuAddress() a const member function 
This doesn't modify any internal state, so it can be made a const member
function to allow its use in const contexts.
