program_metadata: Avoid reference binding to misaligned address
|
| | |
| |
| |
| |
| |
| | |
Avoids a reference binding to a misaligned addresses. Unpacking one
requires unpacking the other, otherwise there'll be a misaligned address
on the leftover one.

* Wrong alignment in u64 LOG_DEBUG -> memcpy.
* Huge shift exponent in stride calculation for linear buffer, unused result -> skipped.
* Large shift in buffer cache if word = 0, skip checking for set bits.
Non of those were critical, so this should not change any behavior.
At least with the assumption, that the last one used masking behavior, which always yield continuous_bits = 0.

Sets a default size of 0x1FE00000 bytes (510 MiB) for the system_resource_size when a NPDM is not present.

|
| |
Same behavior, minus unnecessary inclusions where not necessary.

- We need this for homebrew process initialization.

This implements svcMapPhysicalMemory/svcUnmapPhysicalMemory for Yuzu,
which can be used to map memory at a desired address by games since
3.0.0.
It also properly parses SystemResourceSize from NPDM, and makes
information available via svcGetInfo.
This is needed for games like Super Smash Bros. and Diablo 3 -- this
PR's implementation does not run into the "ASCII reads" issue mentioned
in the comments of #2626, which was caused by the following bugs in
Yuzu's memory management that this PR also addresses:
* Yuzu's memory coalescing does not properly merge blocks. This results
in a polluted address space/svcQueryMemory results that would be
impossible to replicate on hardware, which can lead to game code making
the wrong assumptions about memory layout.
* This implements better merging for AllocatedMemoryBlocks.
* Yuzu's implementation of svcMirrorMemory unprotected the entire
virtual memory range containing the range being mirrored. This could
lead to games attempting to map data at that unprotected
range/attempting to access that range after yuzu improperly unmapped
it.
* This PR fixes it by simply calling ReprotectRange instead of
Reprotect.

Needed for KIP loading as KIPs do not have an NPDM but do have the essential parts of the data within.

BitField has been trivially copyable since
e99a14862841841d74be8d0ea9426c2d23546b5e, so we can eliminate these
TODO comments and use ReadObject() directly instead of memcpying the
data.

Provides extra information that makes it easier to tell if an executable
being run is using a 36-bit address space or a 39-bit address space.
While we don't support AArch32 executables yet, this also puts in
distinguishing information for the 32-bit address space types as well.

While we're at it, we can also toss out the leftover capability parsing
from Citra.

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.

Several classes have a lot of non-trivial members within them, or don't
but likely should have the destructor defaulted in the cpp file for
future-proofing/being more friendly to forward declarations.
Leaving the destructor unspecified allows the compiler to inline the
destruction code all over the place, which is generally undesirable from
a code bloat perspective.

Cuts down on include dependencies, resulting in less files that need to
be rebuilt when certain things are changed.

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).
