Fixes a crash which could occur in platforms which do not support
buffer_storage, and EFB2RAM is enabled (which indirectly uses the
attributeless buffer).
While the code is namespaced out properly, the files weren't separated
into their own directory. This moves the files so that introducing a general
interface is easier in the future for supporting other architectures.
Lowest hanging fruit I could find with a profiler.
Not sure this stuff actually needs to be done, but assuming it is, why
not do it quickly? 10x faster, goes from 1% CPU to 0.09%.
Yes, this commit is only to blame OSX and Mali. Through the former supports unsynchronized mappings, the latter supports *no* way to stream dynamic data at all. Let's try to make bad news, as they ignore friendly feature requests. Maybe we just need to make more noise...
Some locales use non-breaking spaces as separators, so getting the
encoding right is important. If DolphinWX gets a string that isn't
valid UTF-8, it flat out won't display the string.
This enables shaders to be compiled while the game is starting, instead
of blocking startup. If a shader is needed before it is compiled,
emulation will block.
As these are stored in a map, operator< will become a hot function when
doing lookups, which happen every frame. std::tie generated a rather
large function here with quite a few branches.
We would want to improve the granularity here in the future, but for
now, this should avoid any performance loss from switching to the
VideoCommon shader cache.
This saves us from having to call GetPath when the same file is being
read over and over. (GetPath is more expensive than GetOffset due to
it iterating through parts of the file system and creating strings.)
The original reason I wanted to do this was so that we can replace
the Android-specific code with this in the future, but of course,
just deduplicating between DolphinWX and DolphinQt2 is nice too.
Fixes:
- DolphinQt2 showing the wrong size for split WBFS disc images.
- DolphinQt2 being case sensitive when checking if a file is a DOL/ELF.
- DolphinQt2 not detecting when a Wii banner has become available
after the game list cache was created.
Removes:
- DolphinWX's ability to load PNGs as custom banners. But it was
already rather broken (see https://bugs.dolphin-emu.org/issues/10365
and https://bugs.dolphin-emu.org/issues/10366). The reason I removed
this was because PNG decoding relied on wx code and we don't have any
good non-wx/Qt code for loading PNG files right now (let's not use
SOIL), but we should be able to use libpng directly to implement PNG
loading in the future.
- DolphinQt2's ability to ignore a cached game if the last modified
time differs. We currently don't have a non-wx/Qt way to get the time.
