Fernando Sahmkow e00d992848 GPUMemoryManager: Improve safety of memory reads. 2020-04-08 12:08:06 -04:00
Fernando Sahmkow 7fcd0fee6d Buffer Cache: Use vAddr instead of physical memory. 2020-04-06 09:23:06 -04:00
Fernando Sahmkow 27cbb75e7c PageTable: move backing addresses to a children class as the CPU page table does not need them. 
This PR aims to reduce the memory usage in the CPU page table by moving
GPU specific parameters into a child class. This saves 1Gb of Memory for
most games.

Lioncash 716fbaef74 video_core/memory_manager: Mark IsBlockContinuous() as a const member function 
Corrects the typo in its name and marks the function as a const member
function, given it doesn't actually modify memory manager state.
 2019-05-09 19:14:36 -04:00
Lioncash d4bcd006b2 video_core/memory_manager: Mark the constructor as explicit 
Prevents implicit converting constructions of the memory manager.
 2019-05-09 19:10:26 -04:00
Lioncash fd12788967 video_core/memory_manager: Default the destructor within the cpp file 
Makes the class less surprising when it comes to forward declaring the
type, and also prevents inlining the destruction code of the class,
given it contains non-trivial types.
 2019-05-09 19:10:13 -04:00
Lioncash 53afe47cec video_core/memory_manager: Amend doxygen comments 
Corrects references to non-existent parameters and corrects typos.
 2019-05-09 19:09:19 -04:00
Lioncash 5235b053b4 video_core/memory_manager: Remove superfluous const from function declarations 
These are able to be omitted from the declaration of functions, since
they don't do anything at the type system level. The definitions of the
functions can retain the use of const though, since they make the
variables immutable in the implementation of the function where they're
used.

Fernando Sahmkow d0082de82a Implement IsBlockContinous

memory.

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.
 2019-04-05 20:30:48 -04:00
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.
 2019-04-05 20:28:44 -04:00
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.
 2019-04-05 20:22:55 -04:00
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.
 2019-04-05 20:18:29 -04:00
bunnei 2117edd0f8 memory_manager: Cleanup FindFreeRegion. 2019-03-20 23:12:28 -04:00
