MerryMage 67a70bd9e1 ARM_Interface: Implement PageTableChanged 8 years ago
MerryMage 4e5eb2044a memory: Remove GetCurrentPageTablePointers 8 years ago
MerryMage c02bbb7030 memory: Add GetCurrentPageTable/SetCurrentPageTable 
Don't expose Memory::current_page_table as a global.

B3n30 813837c5cf Merge pull request #2842 from Subv/switchable_page_table 
Kernel/Memory: Give each process its own page table and allow switching the current page table upon reschedule

Subv f18a176b60 Kernel/Memory: Make IsValidPhysicalAddress not go through the current process' virtual memory mapping. 8 years ago
Subv 214150f00c Kernel/Memory: Changed GetPhysicalPointer so that it doesn't go through the current process' page table to obtain a pointer. 8 years ago
Subv 6d2734a074 Kernel/Memory: Give each Process its own page table. 
The loader is in charge of setting the newly created process's page table as the main one during the loading process.

danzel 8266064796 Use recursive_mutex instead of mutex to fix #2902 8 years ago
James Rowe 61442d6afb Merge pull request #2839 from Subv/global_kernel_lock 
Kernel/HLE: Use a mutex  to synchronize access to the HLE kernel state between the cpu thread and any other possible threads that might touch the kernel (network thread, etc).

Subv f484927ed0 Kernel/Memory: Acquire the global HLE lock when a memory read/write operation falls outside of the fast path, for it might perform an MMIO operation. 8 years ago
Weiyi Wang 045d0b5bbd Merge pull request #2799 from yuriks/virtual-cached-range-flush 
Add address conversion functions returning optional, Add function to flush virtual region from rasterizer cache
 8 years ago
Yuri Kunde Schlesner d553135748 Memory: Add function to flush a virtual range from the rasterizer cache 
This is slightly more ergonomic to use, correctly handles virtual
regions which are disjoint in physical addressing space, and checks only
regions which can be cached by the rasterizer.

Yuri Kunde Schlesner f2a5a77e27 Memory: Fix crash when unmapping a VMA covering cached surfaces 
Unmapping pages tries to flush any cached GPU surfaces touching that
region. When a cached page is invalidated, GetPointerFromVMA() is used
to restore the original pagetable pointer. However, since that VMA has
already been deleted, this hits an UNREACHABLE case in that function.

Now when this happens, just set the page type to Unmapped and continue,
which arrives at the correct end result.

Yuri Kunde Schlesner 6ae0086b39 Memory: Add TryVirtualToPhysicalAddress, returning a boost::optional 8 years ago
Yuri Kunde Schlesner 326e7c7020 Memory: Make PhysicalToVirtualAddress return a boost::optional 
And fix a few places in the code to take advantage of that.

Yuri Kunde Schlesner d3db770cad Memory: Add constants for the n3DS additional RAM 
This is 4MB of extra, separate memory that was added on the New 3DS.

bunnei 4798b1d04d Revert "Memory: Always flush whole pages from surface cache" 8 years ago
Yuri Kunde Schlesner f2b9be9bd3 Memory: Always flush whole pages from surface cache 
This prevents individual writes touching a cached page, but which don't
overlap the surface, from constantly hitting the surface cache lookup.

James Rowe bbe57a66ca Expose page table to dynarmic for optimized reads and writes to the JIT 9 years ago
wwylele 3f87d70f0e memory: fix IsValidVirtualAddress for RasterizerCachedMemory 
RasterizerCachedMemory doesn't has pointer but should be considered as valid
 9 years ago
Yuri Kunde Schlesner 84fbbe2629 Use negative priorities to avoid special-casing the self-include 9 years ago
Emmanuel Gil Peyrot ebdae19fd2 Remove empty newlines in #include blocks. 
This makes clang-format useful on those.

Also add a bunch of forgotten transitive includes, which otherwise
prevented compilation.

Emmanuel Gil Peyrot dc8479928c Sources: Run clang-format on everything. 9 years ago
wwylele b2df959733 Memory: add ReadCString function 9 years ago
Subv 0aef634a54 Memory: Handle RasterizerCachedMemory and RasterizerCachedSpecial page types in the memory block manipulation functions. 9 years ago

Gareth Poole be217bca70 Fixed spelling errors 10 years ago
Lioncash 9cf1cfe3fd memory: Get rid of pointer casts 10 years ago
Yuri Kunde Schlesner 74d4bc0af1 Kernel: Add more infrastructure to support different memory layouts 
This adds some structures necessary to support multiple memory regions
in the future. It also adds support for different system memory types
and the new linear heap mapping at 0x30000000.

Yuri Kunde Schlesner e2c7954be5 Memory: Move address type conversion routines to memory.cpp/h 
These helpers aren't really part of the kernel, and mem_map.cpp/h is
going to be moved there next.

Emmanuel Gil Peyrot 2d044a67c9 Common: Cleanup memory and misc includes. 10 years ago
Yuri Kunde Schlesner 0a60aa75c2 Kernel: Add VMManager to manage process address spaces 
This enables more dynamic management of the process address space,
compared to just directly configuring the page table for major areas.

This will serve as the foundation upon which the rest of the Kernel
memory management functions will be built.

Yuri Kunde Schlesner 52158c1b8d Memory: Read SharedPage directly from Memory::Read 10 years ago
Yuri Kunde Schlesner ec514b16a6 Memory: Read ConfigMem directly from Memory::Read 10 years ago
Yuri Kunde Schlesner 7ada357b2d Memmap: Re-organize memory function in two files 
memory.cpp/h contains definitions related to acessing memory and
configuring the address space
mem_map.cpp/h contains higher-level definitions related to configuring
the address space accoording to the kernel and allocating memory.
