* core: memory: Updates for new VMM.bunnei2020-04-171-14/+1
|
* core: memory: Move to Core::Memory namespace.bunnei2020-04-171-2/+2
| | | | - helpful to disambiguate Kernel::Memory namespace.
* Memory: Address Feedback.Fernando Sahmkow2020-04-081-0/+68

* Buffer Cache: Use vAddr instead of physical memory.Fernando Sahmkow2020-04-061-0/+10
|
* core/memory: Create a special MapMemoryRegion for physical memory.Markus Wick2020-01-181-1/+15
| | | | This allows us to create a fastmem arena within the memory.cpp helpers.
* core/memory; Migrate over SetCurrentPageTable() to the Memory classLioncash2019-11-271-4/+7
| | | | | | | Now that literally every other API function is converted over to the Memory class, we can just move the file-local page table into the Memory implementation class, finally getting rid of global state within the memory code.
* core/memory: Migrate over Write{8, 16, 32, 64, Block} to the Memory classLioncash2019-11-271-9/+88
| | | | | | | | | The Write functions are used slightly less than the Read functions, which make these a bit nicer to move over. The only adjustments we really need to make here are to Dynarmic's exclusive monitor instance. We need to keep a reference to the currently active memory instance to perform exclusive read/write operations.
* core/memory: Migrate over Read{8, 16, 32, 64, Block} to the Memory classLioncash2019-11-271-7/+78
| | | | | | | | | | | | | | With all of the trivial parts of the memory interface moved over, we can get right into moving over the bits that are used. Note that this does require the use of GetInstance from the global system instance to be used within hle_ipc.cpp and the gdbstub. This is fine for the time being, as they both already rely on the global system instance in other functions. These will be removed in a change directed at both of these respectively. For now, it's sufficient, as it still accomplishes the goal of de-globalizing the memory code.
* core/memory: Migrate over ZeroBlock() and CopyBlock() to the Memory classLioncash2019-11-271-2/+51
| | | | | These currently aren't used anywhere in the codebase, so these are very trivial to move over to the Memory class.
* core/memory: Migrate over RasterizerMarkRegionCached() to the Memory classLioncash2019-11-271-5/+10
| | | | | This is only used within the accelerated rasterizer in two places, so this is also a very trivial migration.
* core/memory: Migrate over ReadCString() to the Memory classLioncash2019-11-271-2/+17
| | | | | This only had one usage spot, so this is fairly straightforward to convert over.
* core/memory: Migrate over GetPointer()Lioncash2019-11-271-2/+20
| | | | | With all of the interfaces ready for migration, it's trivial to migrate over GetPointer().
* core/memory: Migrate over address checking functions to the new Memory classLioncash2019-11-271-3/+21
| | | | | | | | | A fairly straightforward migration. These member functions can just be mostly moved verbatim with minor changes. We already have the necessary plumbing in places that they're used. IsKernelVirtualAddress() can remain a non-member function, since it doesn't rely on class state in any form.
* core/memory: Migrate over memory mapping functions to the new Memory classLioncash2019-11-271-0/+59
| | | | | | Migrates all of the direct mapping facilities over to the new memory class. In the process, this also obsoletes the need for memory_setup.h, so we can remove it entirely from the project.
* core/memory: Introduce skeleton of Memory classLioncash2019-11-271-0/+21
| | | | | | | | | Currently, the main memory management code is one of the remaining places where we have global state. The next series of changes will aim to rectify this. This change simply introduces the main skeleton of the class that will contain all the necessary state.
* memory: Remove unused PageTable forward declarationLioncash2019-07-061-4/+0
| | | | This isn't used by anything in the header file, so it can be removed.
* core/memory: Remove unused FlushMode enumLioncash2019-05-071-9/+0
| | | | | Recent changes to memory-related code resulted in this being unused, so we can remove it.
* core/cpu_core_manager: Create threads separately from initialization.Lioncash2019-04-121-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our initialization process is a little wonky than one would expect when it comes to code flow. We initialize the CPU last, as opposed to hardware, where the CPU obviously needs to be first, otherwise nothing else would work, and we have code that adds checks to get around this. For example, in the page table setting code, we check to see if the system is turned on before we even notify the CPU instances of a page table switch. This results in dead code (at the moment), because the only time a page table switch will occur is when the system is *not* running, preventing the emulated CPU instances from being notified of a page table switch in a convenient manner (technically the code path could be taken, but we don't emulate the process creation svc handlers yet). This moves the threads creation into its own member function of the core manager and restores a little order (and predictability) to our initialization process. Previously, in the multi-threaded cases, we'd kick off several threads before even the main kernel process was created and ready to execute (gross!). Now the initialization process is like so: Initialization: 1. Timers 2. CPU 3. Kernel 4. Filesystem stuff (kind of gross, but can be amended trivially) 5. Applet stuff (ditto in terms of being kind of gross) 6. Main process (will be moved into the loading step in a following change) 7. Telemetry (this should be initialized last in the future). 8. Services (4 and 5 should ideally be alongside this). 9. GDB (gross. Uses namespace scope state. Needs to be refactored into a class or booted altogether). 10. Renderer 11. GPU (will also have its threads created in a separate step in a following change). Which... isn't *ideal* per-se, however getting rid of the wonky intertwining of CPU state initialization out of this mix gets rid of most of the footguns when it comes to our initialization process.

|\ | | | | core/memory: Minor simplifications to page table management
| * core/memory: Remove GetCurrentPageTable()Lioncash2019-04-071-2/+1
| | | | | | | | | | Now that nothing actually touches the internal page table aside from the memory subsystem itself, we can remove the accessor to it.

* core/memory: Remove unnecessary includesLioncash2019-03-211-3/+0
| | | | | | | In 93da8e0abfcdcc6e3cb5488a0db12373429f1377, the page table construct was moved to the common library (which utilized these inclusions). Since the move, nothing requires these headers to be included within the memory header.

* memory: Dehardcode the use of fixed memory range constantsLioncash2018-09-251-30/+1
| | | | | | | | The locations of these can actually vary depending on the address space layout, so we shouldn't be using these when determining where to map memory or be using them as offsets for calculations. This keeps all the memory ranges flexible and malleable based off of the virtual memory manager instance state.
* memory: Dehardcode the use of a 36-bit address spaceLioncash2018-09-251-11/+21
| | | | | Given games can also request a 32-bit or 39-bit address space, we shouldn't be hardcoding the address space range as 36-bit.
