bunnei a609b6907a Kernel/Memory: Added a function to first a suitable guest address at which to allocate a region of a given size. 7 years ago
Lioncash 33830aa65a svc: Add missing sanitizing checks for MapSharedMemory/UnmapSharedMemory 
Now that the changes clarifying the address spaces has been merged, we
can wrap the checks that the kernel performs when mapping shared memory
(and other forms of memory) into its own helper function and then use
those within MapSharedMemory and UnmapSharedMemory to complete the
sanitizing checks that are supposed to be done.

Lioncash 90f8474fc1 svc: Clarify enum values for AddressSpaceBaseAddr and AddressSpaceSize in svcGetInfo() 
So, one thing that's puzzled me is why the kernel seemed to *not* use
the direct code address ranges in some cases for some service functions.
For example, in svcMapMemory, the full address space width is compared
against for validity, but for svcMapSharedMemory, it compares against
0xFFE00000, 0xFF8000000, and 0x7FF8000000 as upper bounds, and uses
either 0x200000 or 0x8000000 as the lower-bounds as the beginning of the
compared range. Coincidentally, these exact same values are also used in
svcGetInfo, and also when initializing the user address space, so this
is actually retrieving the ASLR extents, not the extents of the address
space in general.

Lioncash 6c6f95d071 svc: Report correct memory-related values within some of the cases in svcGetInfo() 
Previously, these were reporting hardcoded values, but given the regions
can change depending on the requested address spaces, these need to
report the values that the memory manager contains.

Lioncash 7fd598636e memory: Dehardcode the use of a 36-bit address space 
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.

Lioncash 75603b005b process/vm_manager: Amend API to allow reading parameters from NPDM metadata 
Rather than hard-code the address range to be 36-bit, we can derive the
parameters from supplied NPDM metadata if the supplied exectuable
supports it. This is the bare minimum necessary for this to be possible.

The following commits will rework the memory code further to adjust to
this.

Lioncash 7c9644646f
general: Make formatting of logged hex values more straightforward 
This makes the formatting expectations more obvious (e.g. any zero padding specified
is padding that's entirely dedicated to the value being printed, not any pretty-printing
that also gets tacked on).

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.

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.
