Some games (like Xenoblade Chronicles 2) clear both depth and stencil
buffers while there's a depth-only texture attached (e.g. D16 Unorm).
This commit reads the zeta format of the bound surface on
ConfigureFramebuffers and returns if depth and/or stencil attachments
were set. This is ignored on DrawArrays but on Clear it's used to just
clear those attachments, bypassing an OpenGL error.
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.
std::moveing a local variable in a return statement has the potential to
prevent copy elision from occurring, so this can just be converted into
a regular return.
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.
According to documentation, if the argument of std::exp is zero, one is returned.
However we want the return value to be also zero in this case so no audio is played.
Commercial games assume that this value is 1 but they never set it. On
the other hand nouveau manually sets this register. On
ConfigureFramebuffers we were asserting for what we are actually
implementing (according to envytools).
With shader caches on the horizon, one requirement is to provide visible
feedback for the progress. The shader cache reportedly takes several
minutes to load for large caches that were invalidated, and as such we
should provide a loading screen with progress.
Adds a loading screen widget that will be shown until the first frame of
the game is swapped. This was chosen in case shader caches are not being
used, several games still take more than a few seconds to launch and
could benefit from a loading screen.
