In addition to the default, external, EDID, and internal displays,
there's also a null display provided as well, which as the name
suggests, does nothing but discard all commands given to it. This is
provided for completeness.
Opening a display isn't really a thing to warn about. It's an expected
thing, so this can be a debug log. This also alters the string to
indicate the display name better.
Opening "Default" display reads a little nicer compared to Opening
display Default.
This quite literally functions as a basic setter. No other error
checking or anything (since there's nothing to really check against).
With this, it completes the pm:bm interface in terms of functionality.
This appears to be a vestigial API function that's only kept around for
compatibility's sake, given the function only returns a success error
code and exits.
Since that's the case, we can remove the stubbed notification from the
log, since doing nothing is technically the correct behavior in this
case.
Looking into the implementation of the C++ standard facilities that seem
to be within all modules, it appears that they use 7 as a break reason
to indicate an uncaught C++ exception.
This was primarily found via the third last function called within
Horizon's equivalent of libcxxabi's demangling_terminate_handler(),
which passes the value 0x80000007 to svcBreak.
This is a function that definitely doesn't always have a non-modifying
behavior across all implementations, so this should be made non-const.
This gets rid of the need to mark data members as mutable to work around
the fact mutating data members needs to occur.
These values are not equivalent, based off RE. The internal value is put
into a lookup table with the following values:
[3, 0, 1, 2, 4]
So the values absolutely do not map 1:1 like the comment was indicating.
Avoids entangling the IPC buffer appending with the actual operation of
converting the scaling values over. This also inserts the proper error
handling for invalid scaling values.
This appears to only check if the scaling mode can actually be
handled, rather than actually setting the scaling mode for the layer.
This implements the same error handling performed on the passed in
values.
Within the actual service, it makes no distinguishing between docked and
undocked modes. This will always return the constants values reporting
1280x720 as the dimensions.
This IPC command is simply a stub inside the actual service itself, and
just returns a successful error code regardless of input. This is likely
only retained in the service interface to not break older code that relied
upon it succeeding in some way.
In many cases, we didn't bother to log out any of the popped data
members. This logs them out to the console within the logging call to
provide more contextual information.
Internally within the vi services, this is essentially all that
OpenDefaultDisplay does, so it's trivial to just do the same, and
forward the default display string into the function.
